OBJECTIVES: To evaluate the diagnostic value of MR arthrography (MRA) in diagnosing instability of the LHBT in patients with rotator cuff tendon tear. MATERIALS AND METHODS: The MR arthrograms of 101 patients were retrospectively reviewed and correlated with arthroscopic findings as the standard reference. Images were evaluated for (1) the integrity of the LHBT, (2) the position of the LHBT (subluxation/dislocation on axial images, inferior displacement on oblique sagittal image) and (3) the integrity of the biceps pulley (SGHL, supraspinatus and subscapularis tendon adjacent to the rotator interval)...

BACKGROUND: Total shoulder arthroplasty (TSA) in cases with posterior wear can be addressed by eccentric reaming of the anterior glenoid or by augmenting the posterior glenoid with bone grafting or augmented glenoid implants. We report the results of TSA with posterior glenoid bone grafting (PGBG) with humeral head autograft in patients with shoulder osteoarthritis and severe posterior glenoid wear. METHODS: A retrospective review of cases from 2004 to 2014 revealed 34 patients...

PURPOSE: Fractures of the base of the middle phalanx are particularly challenging. Dorsal fracture-subluxations/dislocations of the proximal interphalangeal (PIP) joint are relatively common, but the volar fracture-subluxation/dislocation, the so-called "central slip fracture," is quite rare. The current study presents our experience with surgically treated patients with central slip fracture subluxation/dislocation with a minimum of 1 year follow-up. We hypothesized that the majority of patients with a central slip fracture-subluxation/dislocation have poor outcomes...

BACKGROUND: There is no consensus on the optimal method of stabilization (arthroscopic or open) in collision athletes with anterior shoulder instability. PURPOSE: To examine the effect of "subcritical" bone loss and football-specific exposure on the rate of recurrent shoulder instability after arthroscopic stabilization in an intercollegiate American football population. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: Fifty intercollegiate football players underwent primary arthroscopic stabilization for anterior shoulder instability and returned to football for at least a single season...

Shoulder joint dislocation is the most common joint dislocation seen in the emergency department.Traumatic dislocation may cause damage to the soft-tissues surrounding the shoulder joint and sometimes to the bone. The treatment, which aims at restoration of a fully functioning, pain-free and stable shoulder, includes either conservative or surgical management preceded by closed reduction of the acute dislocation.Conservative management usually requires a period of rest, generally involving immobilisation of the arm in a sling, even though it is still debated whether to immobilise the shoulder in internal or external rotation...

BACKGROUND: Resurfacing of the glenohumeral joint for patients with glenohumeral arthritis has gained popularity since the first introduction. We report the mid-term results of the Global C.A.P. uncemented resurfacing shoulder prosthesis (DePuy Synthes). METHODS: From January 2007 to December 2009, 48 humeral cementless resurfacing prostheses in 46 patients were performed. All patients were diagnosed with primary glenohumeral osteoarthritis. Patients were contacted for review; the Constant Score, visual analog pain scale, Dutch Simple Shoulder Test, SF-12 scores and physical examination were assessed both preoperatively and yearly postoperatively...

Minor instability of the shoulder has recently drawn attention as a cause of shoulder pain in athletes. However, it is difficult to correctly diagnose the direction in which the humeral head translates and subluxates, and to clarify the pathology of the instability. We present a case of a 20-year-old male with an unstable shoulder who could not raise his left arm due to pain. Since 6 years prior to the onset of pain, the patient could asymptomatically perform voluntary subluxation, but it was slight and the direction of the subluxation could not be confirmed...

BACKGROUND: Anterior shoulder instability has been successfully managed arthroscopically over the past two decades with refined "anatomic" reconstruction procedures involving the use of anchors for the repositioning and re-tensioning of the antero-inferior capsuloligamentous complex, in an effort to recreate its "bumper effect". METHODS: Research and online content related to arthroscopic treatment of shoulder instability was reviewed and their results compared...

BACKGROUND: Glenohumeral subluxation and glenoid morphology are commonly evaluated in primary osteoarthritis by use of the Walch classification. The reliability of this classification system has been analyzed only by computed tomography (CT). The purpose of this study was to determine the reliability of plain axillary radiographs compared with CT scans. METHODS: Three shoulder surgeons blindly and independently evaluated the radiographs and CT scans of 75 consecutive shoulders with primary glenohumeral osteoarthritis...

BACKGROUND: Stroke and hemiplegia are frequent complications of stroke. This study was performed to sonographically evaluate post-stroke hemiplegic shoulders and explore possible relationship(s) between the sonographic findings and clinical indices. MATERIAL/METHODS: Forty-five stroke patients and 45 age- and sex-matched controls were recruited. Standard sonographic examination of both shoulders was performed to assess for joint subluxation, rotator cuff tears, tendinosis, subacromial-subdeltoid bursitis or effusion and adhesive capsulitis...

BACKGROUND: Posterior humeral subluxation is the main cause of failure of total shoulder arthroplasty. We aimed to compare humeral head subluxation in various reference planes and to search for a correlation with retroversion, inclination, and glenoid wear. MATERIALS AND METHODS: We included 109 computed tomography scans of primary glenohumeral osteoarthritis and 97 of shoulder problems unrelated to shoulder osteoarthritis (controls); all computed tomography scans were reconstructed in the anatomic scapular plane and the glenoid hull plane that we defined...

BACKGROUND: In children with brachial plexus birth palsy (BPBP) undergoing tendon transfers to augment shoulder external rotation, it is unclear whether transfer of the latissimus dorsi with its combined latissimus dorsi and teres major (cLT) versus isolated teres major (iTM) tendon transfer yield different outcomes. METHODS: Records of patients with BPBP who underwent shoulder tendon transfers to augment external rotation were retrospectively reviewed. Transfer type (cLT or iTM) was considered indiscriminate by virtue of surgeon preference...

PURPOSE: Arthroscopic Bankart repair (ABR) provides satisfactory results for recurrent anterior shoulder instability, but the high recurrence rate post-ABR remain a concern. One of the adjunct procedures proposed to improve ABR results is arthroscopic rotator interval closure (ARIC). This study prospectively evaluated the outcomes of ABRs alone compared to combined ABR + ARIC and identified risk factors related to failure of each procedure. METHODS: Thirty-nine consecutive patients (mean age 23...

BACKGROUND: Treatment of young, active patients with symptomatic glenohumeral osteoarthritis, excessive glenoid retroversion, and static posterior humeral subluxation is challenging. Correction of glenoid retroversion may lead to centric loading and perhaps recenter the humeral head. We describe the functional and radiologic outcomes after corrective osteotomy of the glenoid in this population of patients. MATERIALS AND METHODS: In this retrospective study, we included 10 shoulders (8 patients) that were observed for a mean of 33...

BACKGROUND: Loosening of the glenoid component is a primary reason for failure of an anatomic shoulder arthroplasty. Pegged glenoids were designed in an effort to outperform keeled components. This study evaluated the midterm clinical and radiographic survival of a single implant design with implantation of an in-line pegged glenoid component and identified risk factors for radiographic loosening and clinical failure. MATERIALS AND METHODS: There were 330 total shoulder arthroplasties that had been implanted with a cemented, all-polyethylene, in-line pegged glenoid component evaluated with an average clinical follow-up of 7...
