【 摘 要 】

ABSTRACTOBJECTIVE: To evaluate the influence of elbow and forearm range of motion on the distal excursion of the long head of the biceps (LHB). METHODS: The distal excursion of the LHB after tenotomy of the shoulders of eight cadavers was ascertained by measuring the distance between a point marked out on the LHB, 3 cm from the anterolateral border of the acromion, and its position at different degrees of elbow flexion, using a digital pachymeter. The measurements at elbow flexion of 135°, 90°, 45° and 0° were noted: these angles were established using a goniometer. The measurements were made with the forearm in neutral, supination and pronation positions. RESULTS: Differences between the mean measurements of the distal excursion of the LHB (total sample) were observed between the degrees of elbow flexion ( p< 0.01). However, no statistical differences were observed between the different forearm positions, between the sides, genders and ages of the cadavers studied. CONCLUSION: Progressive extension of the elbow caused progressive distal excursion of the LHB, but without interference in the forearm position, gender, side or age of the cadavers studied.
