O w large body of evidence supports the fact that ubluxation and dislocation of the long head of the iceps tendon are relatively common findings associted with rotator cuff pathology. Dislocation of the ong head of the biceps is often linked to chronic egenerative changes seen with impingement synrome and tears in the rotator cuff, especially the ubscapularis tendon. One report states that medi...

Xanthomatous infiltration may rarely affect the rotator cuff muscles and long head of the biceps tendon. It is the deposition of cholesterol within the rotator cuff muscles and long head of the biceps tendon resulting from hyperlipidemia, specifically high triglyceride and total cholesterol levels. As more commonly seen with xanthomatous infiltration and tear of the Achilles tendon, there may a...

There is increased interest of the orthopedic surgeons in treating the pathology of long head of biceps. Although there is some clarity in the result of biceps tenotomy, it is not so clear concerning tenodesis. An open keyhole tenodesis of biceps is shrouded with concerns of primary stability, use of deltopectoral incision, operative pain, technical difficulty to access biceps tendon in case of...

OBJECTIVE To localize the site of motor points within human biceps brachii muscles through surface mapping using electrophysiological method. METHOD We recorded the compound muscle action potentials of each lattice of the biceps brachii in 40 healthy subjects. Standardized reference lines were made as the following: 1) a horizontal reference line (elbow crease) and 2) a vertical reference lin...

The purpose of this study was to measure the change in hamstring muscle thickness between contracting and relaxing conditions following a return to sports after a hamstring muscle strain and thereby evaluate muscle function. Six male track and field sprinters participated in this study. All had experienced a prior hamstring strain injury that required a minimum of 2 weeks away from sport partic...

Anatomic variations in the insertion of the long head of the biceps tendon and superior labral complex have been described (Erickson et al. [1992] AJR Am. J. Roentgenol. 158:1091-1096; Kreitner et al. [1998] AJR Am. J. Roentgenol. 170:599-605; Mariani et al. [1997] Arthroscopy 13:499-501; Vangsness Jr. et al. [1994] J. Bone Joint Surg. Br. 76:951-954). To the authors' knowledge, there have been...

BACKGROUND The superiority of tenotomy vs. tenodesis for surgery on lesions of the long head of the biceps brachii tendon is still under debate. Indeed, high-quality evidence is lacking, mainly because of methodological problems, such as retrospective design, population sample size or lack of patient randomization. METHODS/DESIGN The study will be a two-center, double-blind, randomized, contr...
