BACKGROUND: Although conventional Bankart repair has been the accepted procedure for traumatic anterior glenohumeral instability, the humeral avulsion of the glenohumeral ligament or an elongation of the capsule remains challenging to decide the appropriate treatment. The anatomical knowledge regarding the whole capsule of glenohumeral joint is necessary to accurately treat for the capsular disorders. The aims of the current study were to investigate the anatomical features of capsular attachment and thickness in a whole capsule of glenohumeral joint...

BACKGROUND: This study used a chronic rotator cuff (RC) tear model to investigate the effect of microfracture as a bone marrow-stimulating (BMS) technique for RC healing. METHODS: A chronic retracted RC tendon tear model was created bilaterally in the subscapularis tendons of 20 New Zealand rabbits. The tendons were repaired after 8 weeks using a single-row configuration. Tendons in the right shoulder were repaired in standard fashion (control group). Microfractures were performed in the left shoulders before repair (microfracture group)...

BACKGROUND: The quantification of a subscapularis tendon lesion may be difficult on magnetic resonance imaging, as well as during arthroscopic inspection. Consequently, the surgical decision of whether to only debride a degenerated tendon or to lateralize the more intact tendon portion may be arbitrary. This study aims to quantify the length of the subscapularis tendon as a sign of partial tendon tearing. METHODS: We retrospectively identified 92 magnetic resonance arthrography studies of suspected rotator cuff lesions obtained 3 months before shoulder arthroscopy...

PURPOSE: The aim of this study was to analyse the clinical outcome of a modified Sever-L'Episcopo technique for release of contracted muscles and tendon transfer to restore function of the shoulder joint in patients with Erb's palsy. METHODS: A case series was conducted from March 1988 to November 2009 for 19 patients. The average age at operation was 8.4 years. A single incision via an anterior approach to the shoulder joint was used. Elongation of the pectoralis major and subscapularis was carried out...

We present the long-term results of open surgery for internal shoulder rotational deformity in brachial plexus birth palsy (BPBP). From 1997 to 2005, 207 patients (107 females, 100 males, mean age 6.2 (0.6 to 34)) were operated on with subscapularis elongation and/or latissimus dorsi to infraspinatus transfer. Incongruent shoulder joints were relocated. The early results of these patients has been reported previously. We analysed 118 (64 females, 54 males, mean age 15.1 (7.6 to 34)) of the original patient cohort at a mean of 10...

BACKGROUND: Recent evidence suggests that the rabbit subscapularis tendon may be anatomically, biomechanically, and histologically suitable to study rotator cuff pathology and repair. However, biomechanical comparisons of rotator cuff repairs in this model have not been evaluated and compared to those in human cadaveric specimens. QUESTIONS/PURPOSES: We quantified the biomechanical properties of the repaired rabbit subscapularis tendon after (1) single-row, (2) double-row, and (3) transosseous-equivalent rotator cuff repair techniques and compared the ratios of repairs to previously published data for human repairs...

INTRODUCTION: A computer model quantified and compared muscle lengths and moment arms of two different reverse shoulder arthroplasty humeral tray designs during two different motions. METHODS: The computer model simulated internal/ external rotation and abduction in the scapular plane for the normal shoulder, the 38 mm non-offset, and the 38 mm posterior-superior offset reverse shoulders. Muscle lengths were directly measured for seven muscles during each motion...

We evaluated results at one year after surgical correction of internal rotation deformities in the shoulders of 270 patients with obstetric brachial plexus palsy. The mean age at surgery was 6.2 years (0.6 to 35). Two techniques were used: open subscapularis elongation and latissimus dorsi to infraspinatus transfer. In addition, open relocation was performed or attempted in all patients with subluxed or dislocated joints. A mixed effects model approach was used to evaluate the effects of surgery on internal and external rotation, abduction, flexion and Mallet score...

HYPOTHESIS: Many authors suggest that subscapularis deficiency after shoulder arthroplasty has a negative effect on long-term outcomes. Thus, increasing emphasis has been placed on the technique for repair of the tendon. This study evaluated the biomechanical strength of 3 different repairs: osteotomy, tendon to bone, and a combined method. MATERIALS AND METHODS: Twenty-four paired shoulders from deceased donors were prepared for shoulder arthroplasty. The subscapularis tendon was removed/repaired with the lesser tuberosity in the osteotomy group, was removed periosteally in the bone-to-tendon group, and was tenotomized in the combined group...

PURPOSE: The purpose of this study was to compare the biomechanical properties of transosseous versus suture anchor repair of the subscapularis tendon. We also performed real-time measurement of contact area and pressure of the repair site under rotational loads. METHODS: Six paired human cadaveric shoulders were subjected to rotational loading after repair of the subscapularis tendon. Both shoulders were randomized to transosseous or suture anchor repairs. Real-time pressure sensors were placed between the subscapularis tendon and lesser tuberosity...

The purpose of the study was to compare a single-row repair and a double-row repair technique for the specific characteristics of a complete subscapularis lesion. Ten pairs of human cadaveric shoulder human shoulder specimens were tested for stiffness and ultimate tensile strength of the intact tendons in a load to failure protocol. After a complete subscapularis tear was provoked, the specimens were assigned to two treatment groups: single-row repair (1) and a double-row repair using a "suture bridge" technique (2)...

Transfer of Musculus Latissimus dorsi/M. Teres major to the rotator cuff with or without M. Subscapularis/M. Pectoralis release is a widely used procedure for restoring shoulder abduction and external rotation in squeal of obstetric brachial plexus palsy. After the operation a shoulder abduction orthosis in maximal external rotation and 90 - 100 degrees abduction is utilized following six weeks of immobilization in a shoulder spica cast for protecting the newly transferred muscle from undue elongation. However this in turn may cause contracture of the external rotators...

The value of Sowiński coracoplasty for recurrent, trauma related dislocation of the shoulder was evaluated on the basis of multidirectional clinical, Xray, CT and ultrasound examinations in 15 patients operated on between 18 and 40 years of age. Good results were achieved in 14 cases after 2-14 years follow up. In one case of epileptic patient 4.5 years after surgery traumatic dislocation of the shoulder occurred with a fracture of incorporated bony graft. The authors have proved the coracoplasty performed to be efficient in preventing recurrent dislocation of the shoulder by means of creating new biomedical conditions around the joint...
