BACKGROUND: The concept of onlay design reverse shoulder arthroplasty has been introduced to overcome complications observed with the traditional Grammont-type prosthesis. The aim of this study was to determine the influence of arm lengthening on the short-term clinical outcome in onlay reverse shoulder arthroplasty and investigate the effect of humeral tray offset positioning on arm lengthening and range of motion. METHODS: We retrospectively evaluated 56 patients undergoing reverse shoulder arthroplasty with the Aequalis Ascend Flex prosthesis (Tornier, Bloomington, MN, USA) at a minimum 2 years' follow-up...

BACKGROUND: Glenoid deficiency and erosion (excessive retroversion/inclination) must be corrected in reverse shoulder arthroplasty (RSA) to avoid prosthetic notching or instability and to maximize function, range of motion, and prosthesis longevity. This study reports the results of RSA with an angled, autologous glenoid graft harvested from the humerus (angled BIO-RSA). METHODS: A trapezoidal bone graft, harvested from the humerus and fixed with a long-post baseplate and screws, was used to compensate for residual glenoid bone loss/erosion...

HYPOTHESIS AND BACKGROUND: Chronic opioid therapy is an increasingly used modality for the treatment of osteoarthritis-associated pain. We hypothesized that chronic opioid use would be associated with adverse outcomes in shoulder arthroplasty. METHODS: A retrospective analysis of patients undergoing elective anatomic total shoulder arthroplasty (TSA) and reverse total shoulder arthroplasty (rTSA) at a single institution from 2012-2015 was performed. Patients were stratified by preoperative opioid use (nonusers, short-acting opioid users, and long-acting opioid users), and their postoperative clinical outcomes were assessed...

Lyme disease is caused by the spirochete Borrelia burgdorferi and is carried to human hosts by infected ticks. There are nearly 30,000 cases of Lyme disease reported to the CDC each year, with 3-4% of those cases reporting Lyme carditis. The most common manifestation of Lyme carditis is partial heart block following bacterial-induced inflammation of the conducting nodes. Here we report a 45-year-old gentleman that presented to the hospital with intense nonradiating chest pressure and tightness. Lab studies were remarkable for elevated troponins...

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...

Posterior shoulder instability with glenoid bone loss has only a fraction of the prevalence of anterior instability. Unlike the latter, there is a paucity of literature regarding the treatment of posterior bony Bankart lesions and even less with concomitant reverse Hill-Sachs lesions. This combination of pathology leads to a difficult situation regarding treatment options. We present our technique for arthroscopic repair of a posterior bony Bankart lesion and reverse Hill-Sachs lesion. The importance of proper portal placement cannot be overstated...

The estrogen receptor (ER) is a target for endocrine therapy in breast cancer patients. Individual quantification of ERα and ERβ expression, rather than total ER levels, might enable better prediction of the response to treatment. We recently developed the tracer 2-(18)F-fluoro-6-(6-hydroxynaphthalen-2-yl)pyridin-3-ol ((18)F-FHNP) for assessment of ERβ levels with positron emission tomography (PET). Here we investigated several pharmacokinetic analysis methods to quantify changes in ERβ availability with (18)F-FHNP-PET...

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...

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...

PURPOSE: Bilateral posterior fracture dislocation is a rare injury commonly associated with seizures. When the humeral head defect (reverse Hill-Sachs lesion) is between 20% and 45%, operative fixation using a modified McLaughlin procedure is recommended. This video demonstrates a case of bilateral posterior fracture dislocation after a drug-induced seizure treated with a modified McLaughlin procedure. METHODS: The original McLaughlin procedure involved transfer of the subscapularis tendon from the lesser tuberosity to the reverse Hill-Sachs defect...
