관절경하 상완 이두 건 고정술: 연부 조직 고정 대 골 고정

Abstract

The purpose of our study was to compare the clinical results between arthroscopic bone fixation on intertuberculargroove using suture anchor and soft tissue fixation at the rotaor interval for biceps tenodesis when partial tear orinstability of biceps tendon accompanied with rotator cuff tear. From January 2010 to January 2012, 34 cases whowere performed biceps tenodesis for partial tear or instability were enrolled in our study. Mean follow-up periodwas 30.2 months. Bone fixation using suture anchor was performed in 18 cases, and soft tissue fixation wasperformed in 16 cases. Clinical result was evaluated by pain visual analogue scale (VAS), Speed test, Yergasontest, muscle strength, and Constant score. Pain VAS of cases with soft tissue fixation was significantly higher thanthat of cases with bone fixation at 6 months and final follow-up. Positive results for the final follow-up Speed andYergason test were checked in 4 cases (25%) with soft tissue fixation and 1 (5.6%) with bone fixation. The Popeyedeformity was seen in 4 cases (25%) with soft tissue fixation and 2 (11%) with bone fixation. Constant score wasimproved 47 to 78 in cases with soft tissue fixation and 48 to 86 in cases with bone fixation. In patient with partialtear or instability of biceps tendon accompanied with rotator cuff tear, biceps tenodesis using soft tissue fixationshowed worse result compared with bone fixation because of long duration of the pain. Therefore, when performingthe biceps tenodesis, bone fixation will be recommended.
