Ossur Rebound ROM Adjustable Hinged Elbow Brace Post-Op - Universal Left/Right

A range of motion (ROM) elbow brace is a hinged orthosis that allows the surgeon or therapist to precisely control how much the elbow can bend (flex) and straighten (extend) during recovery. The Ossur Rebound uses a drop-lock hinge with adjustable stops that can be set to limit motion within a specific arc — for example, allowing 30–90 degrees of flexion while blocking full extension. This controlled motion is critical in post-operative rehabilitation because it protects the surgical repair while preventing the joint stiffness and muscle atrophy that result from complete immobilization. As healing progresses, the ROM limits are gradually increased by the treating clinician until full motion is restored.

The ulnar collateral ligament (UCL) is the primary stabilizer of the elbow against valgus (outward) stress — the force generated during overhead throwing. UCL reconstruction, commonly known as Tommy John surgery, involves replacing the torn UCL with a tendon graft (typically from the forearm or hamstring). After surgery, the reconstructed ligament must be protected while the graft undergoes a biological process called ligamentization — where the body remodels the tendon into functional ligament tissue. This process takes 12–18 months. A ROM elbow brace is worn during the early phases of recovery (typically 6–12 weeks) to protect the graft from valgus stress while allowing controlled flexion and extension to prevent stiffness.

The distal humerus is the lower end of the upper arm bone that forms the elbow joint, and the radial head is the top of the radius bone in the forearm. Fractures of these bones are common after falls on an outstretched hand or direct elbow trauma. Stable fractures that do not require surgery are often treated with a period of immobilization followed by early controlled motion in a hinged ROM brace to prevent the severe joint stiffness that commonly develops after elbow fractures. Surgically repaired fractures also require a ROM brace post-operatively to protect the fixation while allowing progressive motion. Early controlled motion is critical for the elbow — this joint is particularly prone to stiffness and heterotopic ossification (abnormal bone formation) if immobilized too long.

Wearing duration depends on the procedure. For UCL reconstruction (Tommy John), the brace is typically worn for 6–12 weeks post-operatively, with return to throwing at 12–18 months. For elbow fracture repair, bracing typically continues for 4–8 weeks with progressive ROM increases. For triceps tendon repair, the elbow is often immobilized in extension for 2–4 weeks before transitioning to a ROM brace for 6–8 additional weeks. For tennis elbow (lateral epicondylitis) release, bracing is typically 2–4 weeks. Your surgeon and physical therapist will provide a specific rehabilitation protocol with milestones for increasing ROM and returning to sport or work activities.

The elbow is one of the most stiffness-prone joints in the body. Even brief periods of immobilization can lead to significant loss of flexion and extension due to capsular contracture (tightening of the joint capsule), scar tissue formation, and heterotopic ossification. Studies show that measurable contracture can occur within just 2–3 weeks of immobilization. A ROM brace prevents this by allowing controlled, progressive motion within a safe arc while still protecting the healing repair. The adjustable stops on the Ossur Rebound allow the treating clinician to gradually increase the permitted range of motion week by week, following a structured rehabilitation protocol that balances protection with mobility.
