BACKGROUND AND PURPOSE: Shoulder instability, a common issue among athletes who engage in contact sports, may lead to recurrent subluxations, or partial dislocations of the shoulder. Young athletic patients generally respond poorly to the nonsurgical treatments for shoulder instability that are commonly utilized. The purpose of this case report is to describe the effects of the treatment guided by the Mulligan Concept (MC) coupled with reflex neuromuscular stabilization (RNS) also known as reactive neuromuscular training (RNT), on an adolescent football player with glenohumeral joint (GHJ) instability who sustained a traumatic anterior subluxation...

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...

BACKGROUND: Arm slings are often used in clinical practice to support the hemiplegic arm aiming to prevent or treat glenohumeral subluxation. Evidence supporting the corrective effect of slings on subluxation is scarce and long-term studies are lacking. AIM: To determine both the immediate and long-term effect on acromiohumeral distance using the Actimove® sling (BSN medical SA-NV, Leuven, Belgium) and Shoulderlift (V!GO, Belgium) and to determine the effect of slings on pain and passive range of motion of the shoulder in stroke patients with glenohumeral subluxation...

BACKGROUND: Computed tomography (CT) scans are often obtained before total shoulder arthroplasty to assess glenoid deformity. To allow correction of the slice axis into the plane of the scapula, these scans have typically required inclusion of the entirety of the scapula. The purpose of this study was to determine whether inclusion of the medial border and inferior angle is necessary for accurate measurement of scapular version, inclination, and humeral subluxation. METHODS: Fourteen CT scans in preoperative total shoulder arthroplasty patients with Walch B2 type glenoids underwent a standardized measurement protocol...

BACKGROUND: Elastic tape has been widely used in clinical practice in order to improve upper limb (UL) sensibility. However, there is little evidence that supports this type of intervention in stroke patients. OBJECTIVE: To verify the effect of elastic tape, applied to the paretic shoulder, on joint position sense (JPS) during abduction and flexion in subjects with chronic hemiparesis compared to sham tape (non-elastic tape). Furthermore, to verify if this potential effect is correlated to shoulder subluxation measurements and sensorimotor impairment...

BACKGROUND: Restoration of soft tissue balance for intraoperative posterior instability during anatomic total shoulder arthroplasty (TSA) is particularly difficult. The effectiveness of posterior capsular plication (PCP) in restoring soft tissue balance is largely unknown. The purpose of this study was to report the outcomes, complications, and reoperations of primary TSA in which a PCP was performed to correct excessive intraoperative posterior subluxation. METHODS: Thirty-eight shoulders (37 patients) underwent PCP for intraoperative posterior instability during anatomic TSA...

EDITORIAL
Brett D Owens
The natural history of a traumatic anterior glenohumeral dislocation has been the subject of significant study, often with differing results depending on the population studied. Most studies have focused on recurrent dislocation as the primary outcome of interest, whereas metrics such as subluxation, return to athletics, and patient-reported outcome scores are also available in limited studies. The known risk factors for recurrence include young age and male gender. Surgical stabilization should be considered in populations at higher risk of recurrence and has been shown in Level I studies to result in reduction of recurrence and improvement in patient-reported outcomes...

BACKGROUND: Total elbow arthroplasty is a treatment for unreconstructable distal humeral fractures; however, longevity of the implant remains a concern in younger, more active patients. Distal humeral hemiarthroplasty (DHH) offers an alternative with multiple advantages. METHODS: This is a retrospective study of 10 patients who underwent DHH for distal humeral fractures during a 4-year period (2008-2012) by a single surgeon. Patients underwent testing of range of motion, Mayo Elbow Performance Score, Disabilities of Arm, Shoulder and Hand, visual analog scale, Single Assessment Numeric Evaluation, and American Shoulder and Elbow Surgeons scores...

REVIEW
A Marinelli, E Guerra, R Rotini
BACKGROUND: In the recent years, considerable improvements have come in biomechanical knowledge about the role of elbow stabilizers. In particular, the complex interactions among the different stabilizers when injured at the same time have been better understood. Anyway, uncertainties about both nomenclature and classification still exist in the definition of the different patterns of instability. MATERIAL AND METHODS: The authors examine the literature of the last 130 years about elbow instability classification, analyzing the intuitions and the value of each of them...
