Biomechanical study of the abductor pollicis longus & extensor pollicis brevis after release and reconstruction of the first dorsal compartment of the wrist.

Background: The purpose of this study was to determine the biomechanical changes after first dorsal compartment release and after Z-plasty of the first dorsal compartment with respect to the excursion and displacement of the abductor pollicis longus and extensor pollicis brevis tendons.

Materials And Methods: Six fresh frozen cadaveric hand and forearms were obtained and the tendons of the abductor were exposed and separated from surrounding tissues through a palmar incision and tenotomized at the musculotendinous junction. The excursion and displacement of the abductor pollicis brevis and flexor pollicis brevis tendons were measured for all six cadaveric hands.

Results of surgical treatment for Sprengle's deformity with vertical corrective scapular osteotomy.

Introduction: Sprengle deformity is the most common congential anomaly of shoulder complex that is the result of scapular placement in cephalad abnormal position. The purpose of this study is the evaluation of clinical and radiological results of vertical corrective scapular osteotomy and comparision of these results with previous studies.

Methods: We retrospectively reviewed the results of the vertical corrective scapular osteotomy (VSO) with or without clavicular osteotomy and wake-up test in 31 consecutive patients at an average duration of follow up of 30 month (6 month-15 years).
