BACKGROUND: In more advanced stages of trapeziometacarpal arthritis, the thumb metacarpal may develop an adduction contracture, leading to secondary hyperextension instability of the metacarpophalangeal joint. Following trapeziometacarpal arthroplasty, uncorrected substantial metacarpophalangeal hyperextension may contribute to ongoing Z-collapse deformity, weakness of pinch and grip, and patient perception of diminished function. METHODS: We prospectively analyzed a consecutive case series of 55 trapeziometacarpal arthroplasty patients (mean age, 60 years; 7 males) who received simultaneous extensor pollicis brevis spiral tenodesis for thumb metacarpophalangeal hyperextension of at least 50°...

PURPOSE: Implantation of a reverse total shoulder arthroplasty (rTSA) places the axillary and suprascapular nerves at risk. The aim of this anatomic study was to digitally analyse the location of these nerves in relation to bony landmarks in order to predict their path and thereby help to reduce the risk of neurological complications during the procedure. METHODS: A total of 22 human cadaveric shoulder specimens were used in this study. The axillary and suprascapular nerves were dissected, and radiopaque threads were sutured onto the nerves without mobilizing the nerves from their native paths...

Glenoid component loosening is a common cause of failed total shoulder arthroplasty. Many different treatment options exist for the management of a symptomatic loose polyethylene glenoid component, ranging from component removal to revision arthroplasty. Arthroscopic removal and conversion to hemiarthroplasty provides a minimally invasive management option that avoids takedown of the subscapularis and allows for humeral prosthesis retention. Frequently, however, osteolysis is encountered concomitantly leading to cavitary glenoid bone deficits at the time of glenoid implant removal, limiting both immediate and future treatment options...

BACKGROUND: With the growth of reverse shoulder arthroplasty (RSA), it is becoming increasingly necessary to establish the most cost-effective methods for the procedure. The surgical approach is one factor that may influence the cost and outcome of RSA. The purpose of this study was to compare the clinical results of a subscapularis- and deltoid-sparing (SSCS) approach to a traditional deltopectoral (TDP) approach for RSA. The hypothesis was that the SSCS approach would be associated with decreased length of stay (LOS), equal complication rate, and better short-term outcomes compared to the TDP approach...

PURPOSES: Shoulder arthroplasty (SA) has been performed by many years for the treatment of several conditions, including osteoarthritis and proximal humeral fractures following trauma. Surgical site infection (SSI) following SA remains a challenge, contributing to increased morbidity and costs. Identification of risk factors may help implementing adequate strategies to prevent infection. We aimed to identify pre- and intra-operative risk factors associated with deep infections after SA...

Periprosthetic joint infection of shoulder arthroplasties is one of the most frequent reasons for pain and revision surgery of shoulder arthroplasties. Propionibacterium acnes is one of the commonest microorganisms causing periprosthetic joint infection in shoulder arthroplasties. It is difficult to detect this slow growing microorganism. This paper gives an overview of the different diagnostic methods. A combination of unspecific and specific tests (detection of microorganism and sensitivity to antibiotics) is helpful in identifying a periprosthetic shoulder infection...

BACKGROUND: In conjunction with reverse total shoulder arthroplasty (RSA), latissimus dorsi and teres major (LD-TM) transfer has been advocated in the setting of combined loss of elevation and external rotation. The purpose of this systematic review is to summarize the clinical outcomes following RSA with LD-TM transfer. METHODS: A search of PubMed, EMBASE, CINAHL, Medline, and Cochrane databases was performed between January 1, 1990 and March 1, 2016 and included articles related to outcomes following RSA with LD-TM transfer...

BACKGROUND: By the time patients with a failed shoulder arthroplasty require revision surgery, a substantial number are older than 80 years. The risk of complications of revision arthroplasty in this elderly population is largely unknown and needs to be considered when contemplating whether these patients are too frail for revision surgery. QUESTIONS/PURPOSES: (1) What are the 90-day medical and surgical complications after revision to reverse shoulder arthroplasty (RSA) in patients older than 80 years? (2) What are the 2- and 5-year survival rates after revision? (3) Was there an improvement in pain at rest or with activity, range of motion (ROM), and strength after revision surgery? METHODS: Between 2004 and 2013, 38 patients who were older than 80 years (84 ± 3 years) underwent revision surgery to a RSA...

BACKGROUND: Propionibacterium acnes (P. acnes) has become increasingly recognized as a cause of periprosthetic joint infection (PJI). QUESTIONS/PURPOSES: It is not currently known if the clinical presentation of P. acnes varies depending on the joint being infected. METHODS: We retrospectively reviewed patients infected with P. acnes after total hip, knee, and shoulder arthroplasty from two institutions. Patients were classified as having a PJI based on the Musculoskeletal Infection Society criteria and were excluded if they had a polymicrobial culture...

BACKGROUND: The number of total shoulder arthroplasties has increased in the past years, with encouraging results. However, the survival of anatomic total shoulder arthroplasty (aTSA) is lower compared with that of knee and hip replacements. Wear-associated problems like loosening are well-known causes of long-term failure of aTSA. The main purpose of this study was to investigate the wear behavior of ceramic-polyethylene bearings compared with the standard metal-polyethylene bearings...
