Effective clavicle fracture rehab protocol implementation begins the moment the initial radiographs confirm the injury and the cast or sling is applied. The clavicle, or collarbone, serves as the primary bony connection between the arm and the torso, stabilizing the shoulder girdle during every pushing or pulling motion. This protocol is designed to guide the patient through a structured progression, balancing the biological healing timeline with the neurological and muscular demands of the surrounding musculature. Success hinges on a disciplined adherence to phases, clear communication with the healthcare team, and a realistic understanding of the timeline required to regain full, pain-free function.
Understanding the Injury and Initial Protection
The clavicle is one of the most frequently broken bones, often resulting from a direct fall onto the shoulder or an outstretched hand. The standard initial treatment typically involves a figure-eight strap or a simple sling to immobilize the shoulder girdle and maintain anatomical alignment during the early inflammatory phase. During this period, the primary goals of the rehab protocol are to control pain and swelling, protect the fracture site, and prevent secondary stiffness in the elbow, wrist, and hand. Gentle isometric contractions of the hand, wrist, and elbow are usually initiated within the first week to maintain circulation and prevent deconditioning without compromising the fracture.
Phase One: Early Protected Motion (Weeks 1 to 4)
As the initial pain and swelling subside, the rehab protocol transitions into controlled passive and active-assisted range of motion. The priority is to maintain mobility in the shoulder, elbow, and wrist while ensuring the fracture remains stable. Patients are guided through pendulum exercises, where the arm is allowed to swing gently in a gravity-eliminated position, promoting synovial fluid movement and preventing adhesive capsulitis. Scapular stabilization exercises focusing on the lower trapezius and serratus anterior become critical to establish a stable base for the eventual restoration of shoulder mechanics.
Key Exercises in Early Phase
Wrist flexion, extension, and circumduction to maintain joint mobility.
Elbow flexion and extension within a pain-free range.
Gentle pendulum or Codman’s exercises to stimulate shoulder circulation.
Scapular retraction and depression while sitting or standing.
Phase Two: Restoring Range of Motion (Weeks 4 to 8)
By the four-week mark, assuming radiographic evidence of callus formation, the protocol advances to active shoulder mobility. The focus shifts to restoring the capsular integrity and neuromuscular coordination lost during the immobilization period. Manual therapy techniques, such as gentle joint mobilizations, are introduced to address any developing capsular restrictions. The patient begins to engage the scapulothoracic joint more dynamically, ensuring that the shoulder blade moves smoothly over the rib cage during elevation and rotation.
Progression Criteria
Progression to this phase is not based solely on the calendar but on specific clinical benchmarks. These include minimal pain at rest, controlled swelling, and the ability to achieve 90 degrees of shoulder flexion without compensatory movements. The rehab protocol carefully monitors the fracture site, ensuring that the mechanical loading applied during exercise does not exceed the biological capacity of the healing bone. X-rays are usually repeated at the six-week mark to verify alignment before advancing to strengthening.
Phase Three: Strength and Neuromuscular Control (Weeks 8 to 12+)
Once full passive range of motion is achieved and the fracture demonstrates solid bridging callus, the protocol introduces progressive resistance. Isometric strengthening transitions into dynamic eccentric and concentric exercises targeting the rotator cuff, deltoid, and upper back musculature. Elastic resistance bands and light dumbbells are incorporated to simulate functional patterns, such as pushing and pulling. Proprioception training becomes essential at this stage, as the joint sensors need to relearn their positioning in space following the trauma and immobilization.
