Effective clavicle fracture rehab protocol implementation begins the moment the initial radiographs confirm the diagnosis. The clavicle, or collarbone, serves as the primary bony connection between the axial skeleton and the upper extremity, making its stability essential for daily function. A structured, progressive protocol ensures that healing occurs in the correct anatomical alignment while minimizing the risk of stiffness, weakness, or re-injury. This framework guides patients and clinicians through a predictable journey from immobilization to full return to activity.
Understanding the Clavicle Fracture Mechanism
Most clavicle fractures result from a direct fall onto the shoulder or an outstretched hand, generating force that travels through the humerus to the clavicle. These injuries are frequently classified by location; midshaft fractures represent the majority of cases and typically follow a predictable healing trajectory. The rehabilitation protocol must account for the specific fracture pattern, including displacement, comminution, and skin integrity, to determine the initial protection phase. Recognizing the biological healing stages—inflammatory, reparative, and remodeling—informs the timing of intervention at each stage.
Immediate Post-Injury Management and Protection
Initial management focuses on pain control, inflammation reduction, and protection of the fracture site. A figure-of-eight strap or a simple sling is commonly used for the first 1 to 2 weeks to minimize gravitational pull and muscle spasm. During this phase, the primary goals are to control edema and maintain motion in the elbow, wrist, and hand. Gentle isometric contractions of the shoulder girdle muscles can be initiated within the first week, provided they do not compromise the fracture alignment or cause significant pain.
Phase 1: Early Healing (Weeks 1 to 4)
The first four weeks center on safeguarding the fracture while combating the secondary complications of immobilization. Therapists guide patients through pendulum exercises, or Codman’s exercises, to maintain passive glenohumeral mobility without active muscle contraction. Edema management continues with elevation and gentle manual lymphatic drainage. As pain diminishes and radiographic callus appears, controlled active-assisted range of motion is introduced, focusing on flexion and external rotation within pain-free limits.
Phase 2: Intermediate Rehabilitation (Weeks 4 to 8)
By weeks 4 to 8, the callus is typically robust enough to support increased loading. The focus shifts to restoring active range of motion and initiating scapulothoracic stabilization. Isometric strengthening of the rotator cuff and periscapular muscles progresses to light resistance using theraband or cuff weights. Neuromuscular control exercises, such as serratus anterior punches and wall slides, are introduced to re-establish proper scapular mechanics during movement. Throughout this phase, the rehab protocol emphasizes quality of motion over quantity, ensuring that the shoulder blade moves smoothly against the rib cage.
Advanced Strengthening and Functional Integration
Between weeks 8 and 12, the protocol advances to address the specific demands of the patient’s lifestyle. Progressive resistance training targets the deltoid, pectoralis major, and latissimus dorsi to restore power to the shoulder complex. Closed kinetic chain exercises, such as modified push-ups on a wall or table, enhance joint congruency and proprioception. This stage requires careful monitoring of alignment; any sign of prominence or pain at the fracture site warrants a regression in load. The goal is to prepare the shoulder for the transition into sport-specific or occupational tasks.
