Recovering from a clavicle fracture requires a strategic blend of patience and targeted movement. The collarbone, or clavicle, acts as a vital strut connecting the arm to the body, and rehabilitation focuses on restoring its strength without compromising the healing bone. This process involves specific exercises designed to improve range of motion, rebuild muscular support, and ultimately return the shoulder to full function.
Understanding the Healing Process
Before initiating any movement, it is essential to respect the biological timeline of bone repair. A clavicle fracture typically progresses through three distinct phases: inflammation, bone production, and bone remodeling. During the initial weeks, the priority is protecting the callus formation, which is the body's natural scaffold for new bone. Introducing stress too early can disrupt this delicate process, making professional guidance from a physiotherapist non-negotiable for a safe recovery.
Phase 1: Early Passive Mobility
In the first few weeks after the injury, the arm is often secured in a sling to align the bone fragments. During this period, exercise is not about strengthening but about preventing stiffness in the surrounding joints. Gentle pendulum swings and passive shoulder rotations allow blood flow to the area without placing pressure on the fracture site. These movements help maintain flexibility in the elbow and wrist, ensuring that the joint above the cast remains mobile.

Rebuilding Strength and Stability
As the bone begins to solidify, usually visible on imaging around the six-week mark, the rehabilitation focus shifts. The surrounding muscles, which atrophied during immobilization, require systematic reactivation. This phase introduces isometrics and controlled resistance to re-establish neuromuscular control. The goal is to create a stable base around the shoulder girdle before progressing to dynamic movements.
Phase 2: Active Assisted and Isometric Exercises
This stage involves moving the shoulder using the opposite hand or a strap to assist the motion. Isometric contractions, where the muscle tenses without changing length, are particularly valuable here. These exercises create muscle tension beneficial for bone loading while keeping the clavicle stable. Activities like gentle shoulder squeezes and wall crawls help restore proprioception—the body's awareness of joint position—without risking impact forces.
Restoring Full Range of Motion
Once the bone has achieved significant union, the complexity of the exercises increases. The scapula, or shoulder blade, plays a critical role in the kinetic chain of the shoulder. If the clavicle is stiff, the scapula cannot glide smoothly, leading to inefficient movement patterns. Specific stretching and mobilization techniques target the joint capsule and soft tissues surrounding the clavicle to ensure the shoulder can rotate fully for everyday activities like reaching behind the back.
