Anterior glenohumeral instability with an irreparable subscapularis tear is a challenging problem for the orthopedic shoulder surgeon. Current techniques, including tendon transfers, yield inconsistent results with high rates of recurrent instability. Acellular dermal allografting has been used in young patients with massive superior rotator cuff tears with early success, but acellular dermal allografting is comparatively unstudied in anterior deficiency. We present two cases of anterior capsular reconstruction with an acellular dermal allograft in patients ages 66 and 58 years with irreparable subscapularis tendon tears. Follow-up for both patients exceeded 4 years, with forward flexion >140°, external rotation exceeding 60°, a Single Assessment Numeric Evaluation score >90 points, a visual analog scale score of 0 points, and an American Shoulder and Elbow Score of 98 points. In conclusion, acellular dermal allografting can be used to reconstruct the anterior capsule in patients with massive irreparable subscapularis tears, similar to its use in superior capsular reconstruction in patients with massive posterosuperior rotator cuff tears.

Background: Chronic subscapularis tendon tear (SBT) is a degenerative disease and a common pathologic cause of shoulder pain. Several potential risk factors for chronic SBT have been reported. Although metabolic abnormalities are common risk factors for degenerative disease, their potential etiological roles in chronic SBT remains unclear. The purpose of this study was to investigate potential risk factors for chronic SBT, with particular attention to metabolic factors. Methods: This study evaluated single shoulders of 939 rural residents. Each subject undertook a questionnaire, physical examinations, blood tests, and simple radiographs and magnetic resonance imaging (MRI) evaluations of bilateral shoulders. Subscapularis tendon integrity was determined by MRI findings based on the thickness of the involved tendons. The association strengths of demographic, physical, social, and radiologic factors, comorbidities, severity of rotator cuff tear (RCT), and serologic parameters for SBT were evaluated using logistic regression analyses. The significance of those analyses was set at p<0.05. Results: The prevalence of SBT was 32.2% (302/939). The prevalence of partial- and full-thickness tears was 23.5% (221/939) and 8.6% (81/939), respectively. The prevalence of isolated SBT was 20.2% (190/939), SBT combined with supraspinatus or infraspinatus tendon tear was 11.9% (112/939). In multivariable logistic regression analysis, dominant side involvement (p<0.001), manual labor (p=0.002), diabetes (p<0.001), metabolic syndrome (p<0.001), retraction degree of Patte tendon (p<0.001), posterosuperior RCT (p=0.010), and biceps tendon injury (p<0.001) were significantly associated with SBT. Conclusions: Metabolic syndrome is a potential risk factor for SBT, as are these factors: overuse activity, diabetes, posterosuperior RCT, increased retraction of posterosuperior rotator cuff tendon, and biceps tendon injury.

목적, 대상 및 방법: 봉합이 불가능한 회전근 개 광범위 파열에 대한 치료로는 보존적 치료, 변연절제술, 부분 봉합술, 건 이전술, 인공 건 이식술 및 역행성 견관절 전치환술 등이 있으나 비교적 젊은 연령이거나 활동성이 높은 환자에서는 견관절의 생역학적 재건으로 force couple을 향상시켜서 견관절의 기능을 호전시키는 건 이전술이 보다 효과적인 치료로 사료된다. 결과 및 결론: 따라서 저자들은 봉합이 불가능한 회전근 개 광범위 파열에서 후상방형 결손에 대해서는 광배근 이전술을 그리고 견갑하건 결손에 대해서는 대흉근 이전술을 소개하고자 한다.

견봉-쇄골 관절 낭종은 비교적 드물게 발생되나, 대부분의 경우 만성적인 회전근 개 질환과 퇴행성 견봉-쇄골관절염에서 동반된다. 이러한 병변에 대한 임상적 해석, 치료적 접근 및 치료 후 합병증을 최소화하기 위해서는 견관절 질환과의 병태생리학적 기전을 이해하는 것이 필수적이라 할 수 있다. 저자들은 단순 흡입술 후 재발되는 견봉-쇄골 낭종에 대한 추가적인 단순 절제술 이후 재발성 무균성의 누공이 합병된 증례와 함께 초음파 검사상 누공을 가진 낭종성 병변과 동반된 광범위한 회전근 개의 파열을 진단하였던 예를 경험하였기에 보고하고자 하며, 문헌고찰을 통하여 견봉-쇄골 관절 낭종의 발생 기전을 고려한 임상적 접근 및 치료적 방법들을 재조명하고자 한다.
