Abstract
No report in the English literature exists on objective muscle testing following the Mumford procedure (distal clavicular resection). Twenty-three athletes, including six at the professional level, were evaluated an average 3.7 years after the Mumford procedure was performed for degenerative changes after a Grade I or Grade II dislocation. All athletes were evaluated with an in depth questionnaire, physical examination, and radiographic study. Seventeen performed Cybex testing of both shoulders. All but one were satisfied with the surgery. Sixteen returned to their same level of sports activity, including five of the six professional athletes. The most common complaint of all those not achieving the pre vious level of sports was the inability to achieve their previous maximum bench press strength. All athletes demonstrated full motion; five exhibited painless crepitation at the acromioclavicular joint. Ten of the twenty-three exhibited increased horizontal clavicular motion. Radiographs demonstrated an aver age of 1.9 cm of bone resection, with varying amounts of ossification present between the remaining clavicle and acromion in eight athletes. The involved limb performed significantly more work than the sound limb in flexion (P = 0.0133) and internal rotation (P = 0.0575) at 300 deg/sec. The involved limb performed significantly more repetitions at 300 deg/sec than the sound limb in the extension plane (P = 0.0373). The sound limb was significantly stronger during ex tension (P = 0.0759) and flexion (P = 0.0063) at 60 deg/sec compared to the involved limb. The sound limb performed significantly more total repetitions at 300 deg/sec in the abduction-adduction plane than the in volved limb (P = 0.0843). The effect of limb dominance on upper extremity strength is reviewed. The authors conclude that the Mumford procedure produced excellent subjective re sults. The majority of the athletes achieved preinjury performance levels after initial clavicle resection for degenerative changes following Grade I or II sprains. While slow speed Cybex testing demonstrated some weakness, faster speed testing showed little or no weakness in fatigue of the involved shoulder.Keywords
