Distal biceps ruptures occur most commonly among young males in their third and fourth decade of life. These injuries are becoming more common, however, as the aging population is remaining active through sport or labour demands. Distal biceps tears or ruptures follow a heavy eccentric load being placed on a shortened or flexed muscle, and often require surgical repair. Functionally, distal biceps injuries cause impairment as this portion of the muscle is largely responsible for supination and flexion at the elbow. Currently there is no consensus regarding post-operative immobilization protocols, and little evidence is available regarding timeframe for early return to functional activities. Existing evidence on functional outcomes post distal biceps tendon repair (DBTR) is of low quality with small sample sizes, and no known RCTs exist comparing early mobilization to immobilization on functional return. Reported timeframes for immobilization range from early controlled motion on day 1 post-operatively to complete immobilization for 6 weeks.
