Polyethylene wear is a known complication in total joint arthroplasty, however, in vivo wear rates in reverse total shoulder arthroplasty (RTSA) remain largely unknown. This study aimed to quantify volumetric and surface deviation changes in retrieved RTSA humeral liners using a novel micro-computed tomography (µCT)-based technique. After IRB-approval, 32 humeral liners (single manufacturer and model) with term-of-service greater than 90 days were analyzed. Clinical demographics and surgical data were collected via chart review...

BACKGROUND: Glenoid component failure is a prevalent mechanical complication of anatomic total shoulder arthroplasty. The objective of this study was to identify surgeon-controlled factors that may be addressed to reduce the rate of glenoid component failure that is sufficiently symptomatic to merit surgical revision. METHODS: We reviewed the clinical and radiographic features of 215 total shoulder arthroplasties that we revised for symptomatic glenoid component failure...

Background: The aim of this study was to investigate which physical and psychosocial work demands were associated with excellent work ability in individuals with neck pain, and to investigate age and sex differences in these associations. Methods: The study sample was obtained from the Statistics Sweden cross-sectional Work Environment survey and consisted of workers who reported neck pain after work (N = 3,212). Results: The findings showed an association between excellent work ability and self-reported low exposure to lifting, twisted work posture, working with hands in shoulder level or higher, and leaning forward without support and combination of exposures containing these work demands...

BACKGROUND: Although reverse total shoulder arthroplasty (RTSA) has been shown to reduce pain and to improve function in most patients, some still suffer from functional limitations. This study aimed to investigate the incidence of poor motion recovery after RTSA and to identify factors that may cause poor outcomes. METHODS: Seventy-six patients who underwent primary RTSA with a reverse-type Aequalis prosthesis (Tornier, Montbonnot, France) were allocated to a satisfactory or unsatisfactory group on the basis of their postoperative active anterior elevation...

BACKGROUND: The anterosuperior (AS) approach for reverse total shoulder arthroplasty (RTSA) has been reported as a risk factor for baseplate malposition because of potential difficulty in glenoid exposure. The objective of this study was to compare glenoid baseplate position between the AS and deltopectoral (DP) approaches in relation to the surgeon's experience and to evaluate the effect of placement on clinical outcomes. METHODS: There were 109 shoulders that underwent RTSA for cuff tear arthropathy or osteoarthritis with cuff tearing by a single surgeon...

CASE: A 53-year-old man presented with osteoarthritis (Walch biconcave [B2] glenoid retroversion, 22°; glenohumeral subluxation index, 65%) and a partial rupture of the supraspinatus tendon in the left shoulder. Following anatomic total joint replacement, he developed disabling recurrent posterior subluxation despite a stable prosthesis and a correctly centered glenoid head, as observed with postoperative radiography and computed tomography. In order to avoid bone loss and the complications associated with revision arthroplasty, we performed arthroscopic reefing of the posterior capsule as an experimental minimally invasive treatment...

CASE: A 41-year-old woman presented 5 years after glenohumeral arthrodesis. She experienced symptomatic relief following conversion to reverse total shoulder arthroplasty, regaining nearly full passive range of motion and >50% of normal active forward flexion, abduction, internal rotation, and external rotation. CONCLUSION: Conversion from glenohumeral arthrodesis to reverse total shoulder arthroplasty in a patient with a functioning deltoid and adequate bone stock may provide symptomatic relief and improved function in the setting of symptomatic glenohumeral arthrodesis refractory to conservative measures...

PURPOSE: Scapular fractures after reverse shoulder arthroplasty (RSA) are often associated with substantial shoulder impairment. Patient outcomes following either conservative or operative treatment have not been favourable, and consensus is lacking on the best treatment approach. We describe a technique for anatomic reconstruction of fractured lateral and basal acromion in patients at higher risk for diminished function or those for which conservative treatment has already failed. METHODS: Of the 95 patients who underwent RSA at our institution between December 2013 and December 2016, three had post-operative acromion fractures (type II)...

BACKGROUND: Implant registries have proved valuable in assessing the outcomes of arthroplasty procedures. Moreover, by identifying lesser quality implants they have indirectly improved the quality of care. The registry of prosthetic shoulder implants was established in 2008. METHODS: It records information on all types of primary and revision arthroplasty procedures involving the glenohumeral joint, including reverse and total arthroplasty, hemiarthroplasty, resurfacing, removal, and any other surgical procedures that are required to manage these patients...

Background: Antibiotic spacers in shoulder periprosthetic joint infection deliver antibiotics locally and provide temporary stability. The purpose of this study was to evaluate differences between stemmed and stemless spacers. Methods: All spacers placed from 2011 to 2013 were identified. Stemless spacers were made by creating a spherical ball of cement placed in the joint space. Stemmed spacers had some portion in the humeral canal. Operative time, complications, reimplantation, reinfection, and range of motion were analyzed...

EDITORIAL
Robert D Graham
Non-arthroplasty treatment options for pseudoparalysis of the shoulder are preferable in the younger patient population. Although there are differing philosophies among shoulder surgeons, many prefer to avoid reversed total shoulder arthroplasty for patients under age 60 years. Arthroscopically assisted latissimus dorsi transfer may be a good alternative for these patients, but how the results compare with arthroscopic superior capsular reconstruction is the question.

Consecutive proximal-to-distal sequencing of motion is considered to be integral for generating high velocity of distal segments in many sports. Simultaneous usage of proximal and distal segments as seen in martial arts is by far less well investigated. Therefore, the aim of the study was to characterise and differentiate the concepts of consecutive (CSM) and simultaneous (SSM) sequence of motion in straight reverse punches as practised in Practical Wing Chun. Four experienced martial artists succeeded an eligibility test for technical proficiency in both concepts and performed a total number of 20 straight punches per concept...
