The aims of this retrospective study were to evaluate the results of inferior capsular shift operation which were approached anteriorly or posteriorly according to a main instability direction in contact sports population who had multidirectional shoulder instability. Fifty-three shoulders in 47 athletes who engaged in contact sports underwent an anterior or posterior inferior capsular shift procedure for the correction of multidirectional instability of the shoulder joint. The surgical approach was selected according to the predominant direction of the instability. Follow up was average of 42 months(24∼73 months). After anterior inferior capsular shift, anterior dislocation was recurred in three shoulders, posterior dislocation in one, and inferior dislocation in two shoulders. After posterior inferior capsular shift, one dislocation occurred anteriorly, one inferiorly and one posteriorly. The excessive tightening of capsule or improper diagnosis could be causative factors for the development of dislocation in the opposite direction to the preoperative major instability. Of six patients who could not return to their sports, five had bilateral repairs. Successful repair based on the criteria of the American shoulder and elbow association was achieved in 92% of anterior repairs, and 81 % of posterior repairs.

Initial treatment of multidirectional instability of the shoulder would be a thorough rehabilitation program. If rehabilitation fails to resolve a patient's symptoms, the most commonly performed surgical procedure remains the inferior capsular shift. Eleven patients who had disabling multidirectional instability of the shoulder were managed with the inferior capsular shift. All of the procedure were performed by means of an anterior approach and a laterally based capsular shift. All of the patients were the contact athletes. The purpose of our study was to evaluate the efficacy of the inferior capsular shift procedure in the contact athletic patients, to review the loss of external rotation postoperatively and to discuss their return to sports. Mean follow up duration was 14.5 months(range, 12 to 24). Pain was relieved postoperatively in all cases and most patients could get stability except one case of recurrent subluxation. The average loss of external rotation and forward flexion after the operation were Y and 30 at last follow up. By the rating scale from American Shoulder and Elbow Society, overall scores improved from 49 points to 85 points. The results were excellent or good in 9 patients(82%) out of 11 patients. In reference to return to sports, 10 patients(91 %) of 11 patients returned to their sports with 7 patients (64%) returning at the same levels of competitiveness. The inferior capsular shift procedure was considered to be a recommendable method for the management of the multidirectional instability of the shoulder.

Purpose: To report the mid-term results of the inferior capsular shift procedure for the multidirectional instability, and to analyze whether the bilateral laxity, the generalized ligamentous laxity and the voluntary instability can influence upon the final outcome. Material and Method: We reviewed 95 patients with 96 shoulders treated by the inferior capsular shift procedure for multidirectional instability through an anterior approach. In total, 49 shoulders(51%) showed generalized ligamentous laxity, 56 shoulders(58%) bilateral laxity, and 65 shoulders(68%) voluntary subluxation. Mean follow-up was 27 months(11-60 months). Result: The final Rowe score was 75 points in patients who had had at least one of the bilateral laxity, generalized ligamentous laxity, or the voluntary subluxation and 84 points without any of these in each element. Seventy-five percent of the bilateral laxity and 87% of the unilateral instability continued to function well without any pain and instability postoperatively. Those with a voluntary(74%), those with an involuntary instability(83%), those with a generalized ligamentous laxity(73%) and without laxity(84%) could do well a daily living activity without instability Eighty-six percent who had had the voluntary instability was eliminated completely the voluntability. Eighty-four percent of the patients stated that they were subjectively satisfied with the status of their shoulder. Nine shoulders(9.4%) had recurrence of symptomatic and disabling instability and theses patients had had at least voluntary instability preoperatively. Seven patients(7.3%) suffered from the stiff shoulder after the inferior capsular shift procedure. Conclusion: The inferior capsular shift procedure in multidirectional instability provided satisfactory results both in objective and subjective terms. Nonetheless, a patient who has a bilateral laxity, a generalized ligamentous laxity or a voluntary instability could be expected less favorable results compared to those with neither of these. A careful selection of the inferior capsular shift procedure for the multidirectional instability is needed before surgery. But our results suggests that a voluntary instability is not always poor candidate for the inferior capsular shift procedure.

Purpose: We analysed the clinical efficacy of inferior capsular shift operation in multidirectional instability of the shoulder joint in terms of functional aspects and patient's satisfaction Materials and Methods: From July, 1998 to March, 2000, we treated 23 cases of multidirectional instability of the shoulder joint with T-shaped inferior capsular shift and/or Bankart repair. All of them have complained of an experience about frank dislocations. Two of them has a voluntary component. We evaluated them according to complication, function, range of motion, stability and patient's satisfaction with an average follow-up of 15 months(the range of 9 to 27 months). Results: Eight cases were atraumatic multidirectional instability and coexisting Bankart lesion were present in 15. There was no redislocation, but one case of symptomatic subluxation, 3 cases of transient nerve palsy and 2 cases of feeling of laxity developed. Limitation of motion after surgery was an average of 3.4° in flexion, and 8.5° in external rotation. With Rowe scoring system, the clinical result was excellent or good in 22 cases and poor in one. According to American shoulder and elbow society, pain score improved to 1.4 from 6.1, and stability score also improved to 1.8 from 9.1. Conclusion: In multidirectional shoulder instability, one should pay attention to finding a coexisting Bankart lesion. In that case, adequate capsular volume reduction by using inferior capsular shift as well as repair of Bankart lesion is needed to get a good surgical outcome.

Purpose: We reviewed the bilateral anterior shoulder instability to evaluate the final outcomes and influencing factors that had effect on the final outcomes. Materials and Methods: Sixteen patients of the bilateral shoulder instability underwent the operative treatment and 15 patients could be followed up average 29 months. There were Bankart lesions in 28 cases and 46% retracted markedly onto the medial side of the glenoid neck. Capsular redundancy could be seen in 50%, but the generalized ligamentous laxity in only two patients. We performed open Bankart repair in 21 cases and arthroscopic repair in 9 cases. Inferior capsular shift was performed in 12 cases of 15 cases in patients who was shown the capular redundancy. Results: The average increment of the forward flexion was 4° postoperatively but the average decrement of the external rotation was 6° postoperatively. After the inferior capsular shift surgery, there were significantly the decrement in external rotation by 13° even though the forward flexion was at the same level comparing with preoperative motion. There were 13 cases(43%) in excellent result, 14 cases(47%) in good and 3 case(l0%) in poor. Rowe score improved from 53 to 87.3 postoperatively. Conclusion : Re-establishing a proper capsular tensioning in a bilateral anterior shoulder instability is critical to ultimate success because there was a redundant laxity in a half and majority of them had marked retraction of an anteroinferior glenohumeral ligament complex. Especially, it should be considered that an unexpected limitation of external rotation could be occurred in the inferior capsular shift surgery.

목적: 이 논문의 목적은 다방향견관절 불안정증의 수술적 치료에 있어서 내측 전하방 관절낭 이동술의 유용성을 알아보고자 함이다. 대상 및 방법: 1998년 3월부터 2003년 12월까지 내측 전하방 관절낭 이동술을 시행한 19명의 환자를 대상으로 하였다. 이들 중 15례에서는 반복적인 탈구를 경험하였으며, 양측성 견관절에서만 이완을 보인 경우가 8례(42.0%), 견관절을 포함한 전신 인대 이완은 11례(58%)였으며 수의성 아탈구가 2례(10.5%)가 있었다. 평균 추시 기간은 24개월이었다(범위: 9-32 개월) 결과: 19례중 18례에서 통증이 호전되었으며, 평균 10도 정도의 외회전 감소가 있었으나 일상생활에 제한은 없었다. 술 후 모든 예에서 재탈구나 아탈구는 없었으나 2례에서는 스포츠 활동에서 불안감을 호소하였다. Rowe점수에서 모든 환자에서 최우수 또는 우수로 나타났으며 혈종 1례 및 가벼운 국소 피부 감염이 1례에서 있었으나 추후 모두 치료되었다. 결론: 다방향 견관절 불안정증에서 내측 전하방 관절낭 이동술은 통증감소, 환자의 만족도 및 견관절 안정성에 있어 만족스러운 결과를 나타냈다. Hill-Sachs병변 및 Bankart병변이 일부 있었으나 만족스러운 결과를 보였다.
