중·장년층에서 견관절 탈구 후에 발생한 회전근 개 파열에 대한 분석과 치료

Purpose: To evaluate clinical features and surgical results for rotator cuff tear secondary to shoulder dislocation in middle-aged and elderly patients. Materials and Methods: We reviewed 19 patients over 50 years of age who had rotator cuff tears combined with shoulder dislocation between October 2004 and October 2008. There were 7 males and 12 females with a mean age 64.7 years (range, 50 to 78 years). The average follow-up duration was 22 months (range, 8 to 56 months). We investigated the number of dislocations, the size of the cuff tear, the presence of Bankart lesions and the time interval from dislocation to surgery. We also investigated the ASES score, UCLA score, SST score, and shoulder range of motion before and after surgery. We analyzed clinical outcomes and contributing factors. Results: ASES scores improved from 30.2 preoperatively to 72.3 postoperatively; UCLA scores improved from 12.9 to 26.5; SST scores improved from 2.4 to 7.3. Range of motion improved significantly: forward flexion, abduction, external rotation and internal rotation were, respectively, $110.8({\pm}39.3)^{\circ}$, $107.7({\pm}40)^{\circ}$, $22.5({\pm}17.6)^{\circ}$ and L5 level preoperatively; postoperatively they were $153.6({\pm}20.6)^{\circ}$, $152.1({\pm}20.8)^{\circ}$, $36.4({\pm}22.7)^{\circ}$ and L1 level. Age, the presence of Bankart lesions and the number of dislocations were not correlated with clinical outcomes. But the size of the cuff tear was correlated with clinical results. Also, the duration from dislocation to surgery was correlated with postoperative UCLA and SST scores (p=0.039, p=0.038). Conclusion: For shoulder dislocation, it is important to achieve early diagnoses of rotator cuff tears in middle-aged and elderly patients. If these injuries are both present, early rotator cuff repair should be performed for better clinical results. 목적: 중 장년층에서 견관절 탈구 후 발생한 회전근 개 파열의 임상양상을 분석하고, 수술적 치료의 결과를 알아보고자 한다. 대상 및 방법: 2004년 10월에서 2008년 10월까지 견관절 탈구와 회전근 개 파열이 동반되어 수술적 치료를 시행한 50세 이상의 환자 19명을 대상으로 하였다. 남자 7명과 여자 12명으로, 평균 나이는 64.7세 (50~78세)였고, 추시 기간은 평균 22개월 (8~56개월) 이었다. 탈구의 횟수, 회전근 개 파열의 크기, 견관절 내 Bankart 병변, 수술까지의 시간 등을 조사하였고, 수술 전, 후의 ASES 점수, UCLA점수, SST 점수 및 운동범위를 측정하여 수술 후의 임상결과 및 결과에 미치는 인자를 알아 보고자 하였다. 결과: ASES 점수는 술 전 30.2점 (${\pm}20.7$)에서 술 후 72.3점 (${\pm}20.3$)으로, UCLA shoulder rating scale은 12.9점 (${\pm}5.2$)에서 26.5점 (${\pm}7.0$)으로. SST 점수는 2.4점 (${\pm}3.3$)에서 7.3점(${\pm}4.2$)으로 향상되었다. 운동 범위는 술 전 전방 거상, 외전, 외회전 및 내회전이 각각 110.8도 (${\pm}39.3$), 107.
