Clavicle Fracture: Rehabilitation and Recovery Times

Clavicle fracture

Introduction to Clavicle Fracture

The clavicle, commonly known as the “collarbone,” is a long, thin bone that connects the sternum to the scapula, forming part of the shoulder girdle. Clavicle fractures are among the most common bone injuries, accounting for approximately 2-5% of all fractures in adults and up to 10-15% in children. They are particularly frequent in athletes and young people following high-energy trauma, but can occur at any age. This article aims to provide a comprehensive overview of clavicle fracture, from its causes and symptoms to diagnosis, available treatments and the rehabilitation pathway, emphasizing the importance of a multidisciplinary approach for optimal recovery.

Anatomy of the Clavicle

The clavicle is a paired bone, shaped like an italic “S,” located horizontally at the base of the neck, above the first rib. It is the only bone that directly connects the upper limb to the trunk, playing a crucial role in shoulder stability and mobility. From an anatomical perspective, three main portions can be distinguished:

• Medial (sternal) end: Articulates with the manubrium of the sternum forming the sternoclavicular joint. This is a relatively robust joint, supported by strong ligaments.
• Body (diaphysis): This is the central part of the clavicle, thinner and curved, and is the most common site of fracture. It presents an anterior curvature in its medial portion and a posterior curvature in the lateral portion.
• Lateral (acromial) end: Articulates with the acromion of the scapula, forming the acromioclavicular joint. This joint is stabilized by acromioclavicular and coracoclavicular ligaments (trapezoid and conoid), which are fundamental for scapular suspension.

The clavicle acts as a strut, keeping the scapula and upper limb away from the thorax, allowing a wide range of shoulder movements. It also protects important underlying neurovascular structures, such as the brachial plexus and subclavian vessels. Its superficial position makes it vulnerable to direct and indirect trauma.

Causes and Mechanism

Clavicle fractures are almost always the result of trauma, which can be direct or indirect. Understanding the mechanism of trauma is fundamental for diagnosis and treatment planning.

• Fall onto the shoulder: This is the most frequent mechanism and responsible for the majority of clavicular fractures. The impact force is transmitted directly to the shoulder, compressing the clavicle against the chest and causing breakage. Common examples include bicycle falls, incidents during contact sports (rugby, American football), falls from height, or accidental slips. The clavicle, acting as a strut, absorbs the impact energy and fractures at its weakest point, usually the middle third.
• Fall onto outstretched hand: Less common than direct fall onto the shoulder, but still significant. In this scenario, the individual falls forward trying to cushion the impact with the hand. The force is transmitted along the upper limb (hand, wrist, forearm, arm) to the shoulder and clavicle, which fractures due to compression or bending. This mechanism is often associated with wrist or elbow fractures.
• Direct trauma: A direct and violent blow to the clavicle can cause a fracture. This can occur in road accidents (e.g., impact of the chest against the steering wheel or seatbelt), combat sports, or falls where a heavy object directly hits the clavicular region. The nature of the fracture in these cases can be more complex, with multiple bone fragments or associated soft tissue injuries.
• Higher-risk sports: Some sports significantly increase the risk of clavicle fractures due to the nature of their activities and the high probability of falls or impacts. These include:
  • Cycling: Falls from bicycle are a very common cause.
  • Rugby, soccer, ice hockey: Contact sports with high energy and risk of collisions.
  • Martial arts: Falls and throwing techniques.
  • Horseback riding: Falls from horses.
  • Skiing and snowboarding: High-speed falls.
  • Motorcycling: Road accidents.
• Less common causes: In rare cases, clavicle fractures can be pathological (due to osteoporosis, tumors, or other conditions that weaken the bone) or stress-related (due to repetitive stresses, typical of athletes performing overhead movements). In newborns, a clavicle fracture can occur during childbirth, especially in cases of shoulder dystocia.

Understanding the injury mechanism is crucial for the doctor to evaluate not only the fracture itself, but also to suspect any associated injuries, such as thoracic trauma (pneumothorax, rib fractures) or neurovascular injuries, which although rare, can be serious.

Classification

The classification of clavicle fractures is essential for guiding therapeutic decisions and estimating prognosis. The most widely accepted classification is Allman’s, which divides fractures based on their anatomical location.

Besides location, other factors considered in classification include degree of displacement (displacement of fragments), comminution (presence of multiple fragments), bone shortening, and presence of skin injuries (open fractures). These characteristics directly influence the choice between conservative and surgical treatment.

Symptoms

Clavicle fracture presents with a set of characteristic signs and symptoms that appear immediately after trauma. Their intensity can vary based on the severity of the fracture and the presence of any associated injuries.

• Acute pain in the clavicle after trauma: This is the most obvious and constant symptom. The pain is localized in the clavicular region and intensifies with any attempt to move the arm or shoulder. It can be described as sharp or throbbing.
• Swelling and bruising in the clavicular region: Inflammation and bleeding of soft tissues surrounding the fracture cause swelling (edema) and the appearance of a bruise (ecchymosis) that may also extend to the chest or arm.
• Visible deformity: In displaced fractures, particularly those of the middle third, a palpable or visible prominence is often present. This is due to displacement of bone fragments, with the medial fragment tending to be elevated by traction of the sternocleidomastoid muscle and the lateral fragment falling inferiorly due to the weight of the arm and lack of support.
• Inability or difficulty raising the arm due to pain: Pain and shoulder instability make any active movement of the upper limb extremely difficult and painful, particularly elevation or abduction.
• Antalgic posture: The patient spontaneously assumes a position that minimizes pain. Typically, they support the arm of the affected side with the contralateral hand, keeping it adducted to the body and slightly flexed at the elbow. This reduces tension on the shoulder muscles and the fractured clavicle.
• Drooping shoulder: Due to loss of structural support provided by the clavicle, the shoulder on the affected side appears lowered and shifted forward and medially compared to the healthy side. This is particularly evident in displaced fractures of the middle and lateral third.
• Crepitus on palpation (do not actively seek): If you try to gently move the shoulder or palpate the fracture area, you may feel a “grinding” or “rubbing” sensation (crepitus) due to contact between bone fragments. It is important not to actively seek this sign to avoid causing further pain or damage.
• Neurovascular compression: Although rare, in cases of very displaced fractures or with sharp fragments, injury to nerves (brachial plexus) or blood vessels (subclavian artery and vein) that pass under the clavicle can occur. Symptoms include numbness, tingling, weakness in the hand or arm, pallor, or coldness of the limb.
• Pulmonary injuries: In fractures of the medial third or in high-energy trauma, a bone fragment can perforate the pleura or lung, causing pneumothorax (air in the pleural space) or hemothorax (blood). Symptoms include breathing difficulties, chest pain, and cough.

The presence of one or more of these symptoms after shoulder trauma should always lead to consulting a doctor for immediate evaluation.

Diagnosis

The diagnosis of a clavicle fracture is based on careful history taking, thorough clinical examination, and the use of imaging techniques. The goal is to confirm the fracture, evaluate its severity, and identify any associated injuries.

• History: The doctor gathers information about the mechanism of trauma (how the accident occurred), pain intensity, presence of associated symptoms, and the patient’s clinical history.
• Clinical examination:
  • Inspection: The clavicular region is observed to detect swelling, bruising, visible deformities (prominence or depression), and the patient’s antalgic posture. Skin integrity is also assessed to exclude open fractures.
  • Palpation: The clavicle is gently palpated to identify the point of maximum pain, any crepitus, and the presence of displaced bone fragments.
  • Neurovascular assessment: It is essential to exclude injuries to nerves and blood vessels. The radial and ulnar pulse are checked to assess limb perfusion, skin sensation (to exclude nerve injuries), and finger and wrist motility. The presence of possible associated pneumothorax is also evaluated by listening to respiratory sounds and palpating the chest.
  • Shoulder evaluation: A general shoulder assessment is performed to exclude other concomitant injuries, such as dislocations or scapular fractures.
• Radiography: This is the first-choice examination for diagnosing clavicle fracture.
  • Anteroposterior (AP) projection: Provides a general view of the clavicle and allows identification of most fractures.
  • Additional projections: Oblique projections (e.g. 30° cephalic) or specific ones for the acromioclavicular joint are often performed to better visualize the location, fracture type, degree of displacement (fragment displacement), and possible bone shortening.
  • Radiography is fundamental for distinguishing between middle, lateral, and medial third fractures and for assessing stability.
• CT scan (Computed Tomography): Not always necessary, but indicated in doubtful or complex cases:
  • In medial third fractures, where radiography may be less clear due to overlapping thoracic structures.
  • For more detailed evaluation of displacement, comminution, and shortening, useful for surgical planning.
  • To exclude associated injuries to deep structures, such as blood vessels, nerves, or lungs, especially in high-energy trauma.
  • In case of suspected nonunion or malunion.
• Magnetic Resonance Imaging (MRI): Rarely used for initial diagnosis of clavicle fracture, but can be useful for evaluating associated soft tissue injuries (ligaments, muscles) or to exclude preexisting pathologies.

Accurate diagnosis is the first step in establishing the most appropriate and personalized treatment plan for the patient.

Conservative Treatment

Conservative treatment is the predominant therapeutic choice for most clavicle fractures, particularly for those of the middle third that are undisplaced or minimally displaced. The goal is to promote bone healing while maintaining good alignment and minimizing pain.

Indications:

• Middle third fractures that are undisplaced or minimally displaced (shortening less than 1.5-2 cm).
• Medial third fractures, which are generally stable.
• Stable lateral third fractures (Type I and some Type II according to Neer).
• Patients with contraindications to surgery.

Immobilization:

• Figure-of-eight brace or arm sling: These devices are used to immobilize the shoulder and clavicle for a variable period, generally from 3 to 6 weeks in adults and less in children.
  • The figure-of-eight brace wraps around the shoulders and crosses on the back, keeping the shoulders retracted. The idea is to reduce clavicular shortening and favor fragment alignment. However, its effectiveness in maintaining reduction is debated and may be less comfortable.
  • The arm sling supports the arm and elbow, reducing the weight of the upper limb on the clavicle and relieving pain. It is often considered more comfortable and, in many studies, has proven equally effective as the figure-of-eight brace for healing and functional outcome.
• The choice of brace depends on the doctor’s and patient’s preference, and the specific type of fracture.
• During the immobilization period, movement of the elbow, wrist and fingers is allowed and encouraged from the beginning to prevent joint stiffness and muscle atrophy.

Medications:

• Analgesics (acetaminophen, NSAIDs – Non-Steroidal Anti-Inflammatory Drugs) are prescribed for pain control, especially in the first weeks after trauma. It is important to follow the doctor’s instructions for using these medications.
• Local cryotherapy (ice packs) can be applied to the clavicular region to reduce swelling and pain, especially in the first days.

Healing and follow-up:

• Bone healing is the fracture healing process. In adults, this process generally requires 6-12 weeks, while in children, thanks to greater regenerative capacity of bone, times are shorter (3-6 weeks).
• During the healing period, the patient undergoes periodic radiographic controls to monitor the healing process and fragment alignment.
• A bone prominence (fracture callus) is a normal consequence of the healing process and tends to remodel over time, reducing in size, although a slight prominence may persist, especially in displaced fractures treated conservatively. This usually does not compromise functionality.
• It is essential to follow the doctor’s and physical therapist’s instructions scrupulously to ensure optimal healing and prevent complications.

Surgical Treatment

Surgical treatment of clavicle fracture, known as osteosynthesis, aims to restore bone anatomy, stabilize fragments, and allow early mobilization, especially in selected cases where conservative treatment might not lead to a satisfactory functional outcome.

Indications:

Indications for surgical intervention have become broader in recent years, based on evidence showing better functional outcomes in specific scenarios. Main indications include:

• Displaced fracture with significant shortening: Generally, clavicular shortening greater than 1.5-2 cm is an indication for surgery, as it can lead to chronic pain, shoulder weakness, and altered biomechanics.
• Open fracture: When bone protrudes from the skin, there is a high risk of infection and surgery is necessary for wound cleaning and fracture stabilization.
• Fracture with vascular or nerve risk: If bone fragments threaten or have already damaged the brachial plexus or subclavian vessels, urgent intervention is necessary to decompress and repair structures.
• Displaced and unstable lateral third fracture: These fractures, especially those involving the coracoclavicular ligaments, have a high risk of nonunion and poor functional outcomes with conservative treatment. Surgery aims to restore acromioclavicular joint stability.
• Bilateral fractures: Fracture of both clavicles can severely compromise respiratory function and self-care ability, making intervention necessary for at least one side.
• Polytrauma: In patients with multiple serious injuries, clavicular stabilization can be part of a broader approach to improve pain management and early mobilization.
• High functional demands: Professional athletes or individuals with jobs requiring excellent shoulder functionality can benefit from surgery for faster and more complete return to activity.
• Nonunion: Failed healing of the fracture after an adequate period of conservative treatment.
• Symptomatic malunion: Fracture healing in a non-anatomical position that causes pain or functional limitation.

Surgical technique:

The procedure is performed under general anesthesia. The surgeon makes a skin incision over the clavicle to access the fracture site.

• Reduction and fixation with plate and screws: This is the most common and versatile technique. The surgeon realigns the bone fragments (reduction) and fixes them with a metal plate (usually titanium) and screws. The plate is positioned on the superior or anteroinferior surface of the clavicle, depending on fracture configuration and surgeon preference. Modern plates are precontoured to fit the clavicular curvature and can be locking plates, offering more robust fixation.
• Intramedullary nail fixation: Less common than plating, this technique involves inserting a metal nail inside the medullary canal of the clavicle. It is a less invasive technique, but may be less stable for some fracture configurations and may cause irritation at the nail end.
• Kirschner wire or cerclage fixation: Used mainly for lateral third fractures or in combination with other techniques, but less common as the sole fixation for diaphyseal fractures.

After surgery, the patient is usually immobilized with an arm sling for a short period (1-3 weeks) to protect the wound and allow early mobilization to begin under physical therapist guidance. Plate and screw removal can be considered after healing, especially if they cause irritation or pain, but is not always necessary.

Surgery risks include infection, nerve or vascular injuries, nonunion, implant failure, persistent pain, and the need for a second operation to remove the fixation material.

Rehabilitation

Rehabilitation is a fundamental and indispensable component for complete functional recovery after a clavicle fracture, whether treated conservatively or surgically. A well-structured, personalized rehabilitation program supervised by a physical therapist is crucial for restoring shoulder strength, mobility, and functionality, preventing complications such as stiffness, muscle weakness, and chronic pain.

The rehabilitation pathway is progressive and consists of several phases, which may vary slightly based on fracture type, treatment received, and individual patient response. It is essential that each progression be guided and approved by the orthopedic doctor and physical therapist.

Phase 1 — Protection and early mobilization (weeks 0-3/4)

This phase focuses on protecting the fracture to allow initial healing and preventing stiffness of uninvolved joints.

• Immobilization: The patient will maintain the figure-of-eight brace or arm sling as prescribed by the doctor. Use of the brace is essential to protect the fracture site.
• Pain and swelling management: Application of ice (cryotherapy) to the affected area for 15-20 minutes several times a day, and taking analgesic medications as indicated by the doctor.
• Codman pendulum exercises: These passive or active-assisted exercises are among the first to be introduced. The patient leans forward with the trunk, letting the arm of the affected side swing in small circles (clockwise and counterclockwise) and back/forth. The goal is to gently mobilize the glenohumeral joint without loading the clavicle. 5 minutes, 3 times a day is recommended.
• Active mobilization of elbow, wrist, and fingers: Perform complete flexion/extension movements of the elbow, flexion/extension/deviation of the wrist, and finger movements. This prevents stiffness and maintains muscle tone of distal limbs.
• Hand grip exercises: Squeeze a soft ball or rolled towel to maintain grip strength and stimulate circulation.
• Gentle isometric scapular retraction: Light contractions of muscles between the shoulder blades, without movement, to begin reactivating scapular stabilizers.
• Deltoid isometric contractions: Gently contract the deltoid muscle without lifting the arm or moving the shoulder. This helps maintain muscle tone without stressing the fracture.
• Posture: Maintain good posture to avoid compensations and muscle tension.

Phase 2 — Progressive mobilization (weeks 3/4-6/8)

In this phase, with the beginning of bone callus formation, gradual shoulder mobility recovery begins, always below the pain threshold.

• Gradual brace removal: According to medical indication and based on healing progress. The brace can be removed for exercises and then gradually eliminated during the day.
• Active-assisted shoulder flexion and abduction: Use the healthy arm or a stick to assist movement of the affected arm in flexion (lifting forward) and abduction (lifting sideways). Start with limited range of movement and progress gradually.
• External rotation with stick: Hold a stick with both hands behind the back or in front of the body and use the healthy arm to gently push the affected arm into external rotation.
• Arm elevation along the scapular plane: Movement of the arm forward and slightly sideways (about 30 degrees from the frontal plane), which is biomechanically more natural for the shoulder.
• Active scapular retraction: Exercises to strengthen muscles that pull the shoulder blades back and down, improving scapular stability.
• Stationary bike: Light cardiovascular activity, but with care not to grip the handlebar with the affected hand to avoid stress on the clavicle.
• Gentle stretching: Begin with gentle stretching for the posterior capsule and pectoral muscles, to prevent stiffness and improve flexibility.

Phase 3 — Strengthening (weeks 6/8-12/16)

Once good clinical and radiographic healing is achieved, muscle strengthening program begins to recover strength and endurance.

• Rotator cuff strengthening with elastic band: Exercises for external and internal rotation, abduction and adduction with low-resistance elastic bands. Perform 3 sets of 15 repetitions.
• Deltoid strengthening: Lateral and frontal elevation with light dumbbell (initially 0.5-1 kg), gradually increasing the load.
• Scapular stabilizer strengthening: Exercises like rowing, Y-T-W (arm movements forming these letters, lying prone or standing with elastic band) to strengthen rhomboids, trapezius, and serratus anterior.
• Wall push-ups, then inclined: Start with push-ups against the wall, then progress to push-ups on an inclined plane (e.g. table) and finally on the ground, if tolerated.
• Advanced stretching: Continue and intensify stretching of the pectoral, posterior capsule, and other shoulder muscles to maintain and increase range of motion.
• Proprioception exercises: Exercises to improve shoulder balance and coordination, such as medicine ball movements or exercises on unstable surfaces.

Phase 4 — Return to activities (from 3-4 months onwards)

This phase is dedicated to complete functional recovery and gradual return to sports and work activities, with a focus on preventing recurrences.

• Progressive strengthening with increasing loads: Gradually increase weight and resistance in strengthening exercises, approaching pre-injury loads.
• Sport-specific functional exercises: Simulate specific movements of the sport or work activity, starting with light loads and increasing progressively. For example, for a tennis player, start with serving movements without a ball, then with a light ball, etc.
• Plyometrics and power training: For athletes, plyometric exercises may be introduced to improve muscle power and reactivity.
• Contact sports: Return to contact sports (rugby, soccer, martial arts) is generally allowed after 4-6 months and only after radiographic confirmation of complete healing and optimal functional recovery. It is essential that the doctor gives clearance.
• Cycling: Return to road cycling is often possible after 3 months, with caution on first outings and on safe routes. For mountain biking or more extreme sports, times may be longer.
• Maintenance: Continue with a maintenance exercise program to prevent weakness and stiffness.

Throughout the rehabilitation pathway, communication between patient, doctor, and physical therapist is crucial. The patient must report any pain or discomfort, and the program must be adapted based on progress and individual tolerance. Patience and consistency are key elements for successful recovery.

Prevention

Prevention of clavicle fractures focuses mainly on reducing the risk of trauma, particularly those related to falls and sports. Although not all fractures can be avoided, measures can be adopted to decrease the likelihood of injury.

• Use of protective equipment:
  • Contact sports: In sports like rugby, American football, or hockey, using shoulder and chest protection can help distribute impact and reduce direct force on the clavicle.
  • Cycling and motorcycling: Wearing full helmets and shoulder and body protection can mitigate consequences of falls and accidents.
  • Winter sports: Skiers and snowboarders should consider using back and shoulder protection, in addition to helmets.
• Safe falling techniques:
  • For athletes, particularly those practicing contact sports or martial arts, learning safe falling techniques (such as rolling to disperse impact energy) can reduce fracture risk.
  • For the general population, being aware of surroundings and maintaining balance can prevent accidental falls.
• Improving strength and coordination:
  • A training program that includes exercises for muscle strength (particularly of the shoulder and trunk) and coordination can improve overall stability and ability to react to a fall.
  • Balance and proprioception exercises can be useful, especially for the elderly, to reduce fall risk.
• Safe environment:
  • At home, removing obstacles, securing rugs, improving lighting, and using handrails can prevent falls, especially for the elderly.
  • Keep walking surfaces free from ice, snow, or debris.
• Bone health:
  • Maintain good bone health through a balanced diet rich in calcium and vitamin D, and adequate physical activity, can make bones more resistant to trauma.
  • For people at risk of osteoporosis, it is important to follow medical guidelines for prevention and treatment of the disease.
• Awareness and prudence:
  • Avoid risky behaviors and pay attention during activities that carry a high risk of falls.
  • Do not push physical limits excessively, especially when tired or inadequately prepared.

Adopting these preventive measures can significantly contribute to reducing the incidence of clavicle fractures and associated injuries.

Prognosis

The prognosis for a clavicle fracture is generally excellent, with most patients completely recovering shoulder functionality. However, recovery time and final outcome can be influenced by several factors, including fracture type and severity, patient age, chosen treatment, and adherence to the rehabilitation program.

• Healing: Most clavicle fractures heal without complications. The bone healing process typically requires 6-12 weeks in adults and 3-6 weeks in children. Bone callus formation is a positive sign of healing.
• Functional recovery: With adequate rehabilitation, most patients recover a complete range of motion and normal shoulder strength. Return to daily and sports activities occurs gradually.
• Nonunion: Although rare (incidence of 1-5% in conservatively treated fractures and slightly higher in surgical ones), nonunion occurs when the fracture does not heal within an expected time period (generally 4-6 months). Risk factors include very displaced, comminuted fractures, significant shortening, smoking, advanced age, and some systemic pathologies. Nonunion is often symptomatic (persistent pain, weakness) and may require surgical intervention.
• Malunion: Occurs when the fracture heals in a non-anatomical position. Slight malunion with bone prominence (callus) is common and often asymptomatic. However, significant malunion with shortening or angulation can cause pain, weakness, movement limitation, and in rare cases, neurovascular irritation.
• Chronic pain: Some patients may experience persistent pain in the fracture area, even after healing. This may be due to nerve irritation, residual inflammation, or muscle problems.
• Shoulder stiffness: If mobilization is not started early or if the brace is maintained too long, stiffness of the glenohumeral or acromioclavicular joint can develop.
• Neurovascular injuries: In rare cases, bone fragments can damage the brachial plexus or subclavian vessels, leading to neurological (numbness, weakness) or vascular (circulation problems) issues. These complications require specific treatment and may affect prognosis.
• Surgical complications: If the fracture is treated surgically, complications such as infection, implant failure, irritation from fixation material (which may require removal), or iatrogenic injuries can occur.
• Factors influencing prognosis:
  • Age: Children heal faster and with excellent bone remodeling. The elderly may have longer healing times and greater risk of complications.
  • Smoking: Smoking is a known risk factor for nonunion and slows bone healing.
  • Diabetes and other pathologies: Can negatively affect the healing process.
  • Rehabilitation adherence: A diligent rehabilitation program is fundamental for optimal recovery.

In summary, most clavicle fractures have a favorable prognosis. However, careful management by the doctor and physical therapist is essential to identify and treat any complications early, ensuring the best possible functional outcome.

Recovery Times

Recovery times for a clavicle fracture vary based on numerous factors, including fracture type, patient age, treatment adopted, and individual response to rehabilitation. The following tables provide a general estimate, but it is essential to consult your doctor and physical therapist for personalized evaluation.

Notes on recovery times:

• Bone healing: Refers to the period necessary for the bone to heal. This is monitored through control radiographs. Even after radiographic healing, the bone continues to remodel and strengthen for months.
• Start of active mobilization: Indicates when you can begin actively moving the shoulder without the aid of a brace or external assistance. This is a crucial step in rehabilitation.
• Return to light/daily activities: Includes activities like driving, dressing independently, lifting light objects.
• Return to sport (non-contact): Activities like running, swimming (with caution), road cycling (on safe routes). It is essential that strength and range of motion are almost complete.
• Return to sport (contact): Requires complete bone healing, total recovery of shoulder strength and stability, and doctor’s approval. The risk of re-fracture is higher at this stage.
• Individual factors: The indicated times are averages. Healing can be faster or slower depending on age, general health status, presence of other pathologies (e.g. diabetes), smoking, and adherence to the rehabilitation program.
• Pain: Pain is an important indicator. Progression must occur without causing significant pain.

It is essential not to rush the recovery process and follow the medical-physiotherapy team’s instructions scrupulously to prevent complications and ensure a safe and complete return to your activities.
