BACKGROUND: Glenoid component positioning in revision shoulder arthroplasty is difficult because of distorted anatomic landmarks and scarring in and around the glenoid vault. This study compared glenoid component version in revision total shoulder arthroplasty (TSA) and reverse TSA (RTSA) using traditional instrumentation vs. a generic glenoid targeting guide. METHODS: Radiographs of 50 shoulders undergoing revision arthroplasty were reviewed by an independent reviewer...

There is a need for more effective rehabilitation methods for individuals post-stroke. Occupational Therapy Task-Oriented (TO) approach has not been evaluated in a randomized clinical trial. The purpose of this study was to evaluate functional and impairment efficacies of TO approach on the more-affected Upper Extremity (UE) of persons post-stroke. A randomized single-blinded cross-over trial recruited 20 participants post-stroke (mean chronicity = 62 months) who demonstrated at least 10° active more-affected shoulder flexion and abduction and elbow flexion-extension...

BACKGROUND: Reverse total shoulder arthroplasty (RTSA) is now performed at nearly the same rate as anatomic total shoulder arthroplasty in the United States. Repair of the subscapularis is of vital importance in total shoulder arthroplasty; however, its utilization in RTSA has recently been questioned. METHODS: This is a retrospective comparative study from prospectively collected data comparing the outcomes and complications after primary RTSA with or without subscapularis repair...

BACKGROUND: Culture negative prosthetic joint infections (PJI) still remain an issue even with the advantages of the new diagnostic tools for PJI. This is why some orthopedic surgeons have reservations relative to the use of preoperative antibiotic prophylaxis when a PJI is suspected. The purpose of the present study was to evaluate the influence of preoperative antibiotic prophylaxis on intraoperative cultures. MATERIAL AND METHODS: An enhanced diagnostic protocol for PJI (Zimmerli criteria) was used for the inclusion criteria in order to collect all PJI that were seen in a university hospital...

INTRODUCTION: Charcot arthropathy is a rare cause of debilitating joint destruction. Shoulder arthroplasty for Charcot arthropathy is challenging secondary to local bone and soft tissue loss, lack of protective sensation, and altered muscle control. The purpose of this study is to review the outcomes, complications, and survivorship of shoulder arthroplasty for Charcot arthropathy. METHODS: Between January 2000 and December 2011, ten shoulders with Charcot arthropathy were treated with shoulder arthroplasty at our Institution (six hemiarthroplasty, one total shoulder arthroplasty, three reverse shoulder arthroplasty)...

HYPOTHESIS: The objective of the study was to evaluate the development of scapular notching in reverse shoulder arthroplasty by comparing larger glenospheres (42 mm) with smaller glenospheres (38 mm). METHODS: This was a prospective randomized study of 81 patients who had undergone reverse shoulder arthroplasty with a 2-year follow-up. Patients were randomized to receive either a 42-mm glenosphere (38 patients) or a 38-mm glenosphere (43 patients). Scapular notching development was assessed with an anteroposterior radiograph at the end of the follow-up...

Hospital readmissions are costly for patients and institutions. We conducted a study to evaluate rates of readmission within 30 days after anatomical total shoulder arthroplasty (ATSA) and reverse total shoulder arthroplasty (RTSA) and to determine independent risk factors for readmission. We queried the National Surgical Quality Improvement Program database for ATSAs and RTSAs performed between 2011 and 2013 and found a combined total of 3501 cases and an overall readmission rate of 2.7%. Of the readmissions, 67% were for medical complications, and 33% were for surgical complications...

Reported rates of venous thromboembolism (VTE) after shoulder arthroplasty (SA) range from 0.2% to 13%. Few studies have evaluated the incidence of VTE in a large patient population from a single institution. We conducted a study to determine the incidence of VTE (deep venous thrombosis [DVT] and pulmonary embolism [PE]) in a large series of SAs. Cases of SAs performed at our institution between January 1999 and May 2012 were retrospectively reviewed for development of symptomatic VTE within the first 90 days after surgery...

INTRODUCTION: The shoulder arthroplasty brings satisfaction to patients in terms of quality of life and indolence. However whether anatomic implant or reverse, it does not escape from the loosening of the glenoid component. Moreover, optimal implantation is required to ensure the functional outcome without shortening of the arm. The purpose of this study is obtain CT scan evaluation of the glenoid bone stock in order to optimize glenoid component implantation and obtain a reference to determine optimal humeral component placement in case of humeral proximal fracture...

BACKGROUND: Massive rotator cuff tears in active patients with minimal glenohumeral arthritis remain a particular challenge for the treating surgeon. METHODS: A selective literature search was performed and personal surgical experiences are reported. RESULTS: For patients with irreparable rotator cuff tears, a reverse shoulder arthroplasty or a tendon transfer are often performed. However, both procedures have rather high complication rates and debatable long-term results, particularly in younger patients...

BACKGROUND: Patients are often treated with a resurfacing hemiarthroplasty in the expectation that the bone-preserving design facilitates revision should the need for a revision arthroplasty arise. The aim of this study was to report the outcome of patients with glenohumeral osteoarthritis who underwent revision shoulder arthroplasty after resurfacing hemiarthroplasty. METHODS: We reviewed all patients with osteoarthritis reported to the Danish Shoulder Arthroplasty Registry from 2006 to 2013...

BACKGROUND: Neurologic lesions are relatively common after total shoulder arthroplasty. These injuries are mostly due to traction. We aimed to identify the arm manipulations and steps during reverse total shoulder arthroplasty (RTSA) that affect nerve stress. METHODS: Stress was measured in 10 shoulders of 5 cadavers by use of a tensiometer on each nerve from the brachial plexus, with shoulders in different arm positions and during different surgical steps of RTSA...

AIMS: The aim of this study was to analyse human muscle tissue before and after rotator cuff repair to look for evidence of regeneration, and to characterise the changes seen in the type of muscle fibre. PATIENTS AND METHODS: Patients were assessed pre-operatively and one year post-operatively using the Oxford Shoulder Score (OSS) and MRI. The cross-sectional area and distribution of the type of muscle fibre were assessed on biopsies, which were taken at surgery and one year post-operatively...

Massive irreparable rotator cuff tears cause significant shoulder pain and dysfunction. Physical therapy (PT), arthroscopic debridement with biceps tenotomy (AD-BT), and hemiarthroplasty (HA) are treatments shown to reduce pain and improve quality of life. Reverse total shoulder arthroplasty (RTSA) is a newer surgical treatment option that may offer improved function. A cost-effectiveness analysis of these interventions has never been performed, and no head-to-head comparative effectiveness trials currently exist...

OBJECTIVE: Scapular motion is essential for full, functional mobility of the arm. Many shoulder pathologies are associated with alterations of scapular kinematics which have been only little studied in total shoulder arthroplasties. The aim of this study was to compare the 3D scapula kinematics in two groups of patients with total shoulder anatomic (aTSA) or reverse (rTSA) arthoplasties to asymptomatic controls of comparable age during two arm elevation tasks (abduction and flexion) and two simulations of activity of daily living ("hair combing" and "back washing")...

Many patients prioritize the ability to return to sports following shoulder replacement surgeries, including total shoulder arthroplasty (TSA), reverse total shoulder arthroplasty (RTSA), and hemiarthroplasty (HA). While activity levels after hip and knee replacements have been well-established in the literature, studies on this topic in the field of shoulder arthroplasty are relatively limited. A review of the literature regarding athletic activity after shoulder arthroplasty was performed using the PubMed database...

The results of the structural properties of molten copper chloride are reported from high-energy X-ray diffraction measurements, reverse Monte Carlo modeling method, and molecular dynamics simulations using a polarizable ion model. The simulated X-ray structure factor reproduces all trends observed experimentally, in particular the shoulder at around 1 Å(-1) related to intermediate range ordering, as well as the partial copper-copper correlations from the reverse Monte Carlo modeling, which cannot be reproduced by using a simple rigid ion model...

BACKGROUND: With this study, we sought to quantify perioperative changes in driving performance among patients who underwent anatomic or reverse shoulder arthroplasty. METHODS: Using a driving simulator, 30 patients (20 anatomic and 10 reverse total shoulder arthroplasties) were tested preoperatively and at 2 weeks (PO2), 6 weeks (PO6), and 12 weeks (PO12) postoperatively. The total number of collisions, centerline crossings, and off-road excursions (when the vehicle traversed the lateral road edge), and scores on a visual analog scale (VAS) for pain and the Shoulder Pain and Disability Index (SPADI) were recorded at each driving trial...
