Implantation of reverse shoulder endoprostheses is becoming more popular for elderly patients besides the well-established standard anatomic endoprostheses. The reasons for this are the increased life expectancy, age-dependent degeneration of the rotator cuff leading to cuff tear arthropathy, posttraumatic disability after failed osteosynthesis and primary reverse fracture arthroplasty. Stemless implants are more frequently used for primary osteoarthritis with the bone quality being the limiting factor. Modern implant systems allow the stepwise extension from bone preserving primary implants to modular and convertible revision implants that allow a partial exchange of components...

Massive rotator cuff tears are difficult to treat surgically due to retraction, degeneration and fraying of the ends of torn tendons, severe fatty infiltration and atrophy of the respective muscles. Procedures developed to close the gap between the rotator cuff and the greater tuberosity of the humerus, such as soft tissue release may be inadequate for large tears. Human or porcine dermal allografts still have uncertain benefits, and tendon transfers seem to be associated with poor outcomes, donor site morbidity and altered mechanics...

AIM: To evaluate whether implant design, glenoid positioning, and other factors influenced instability and scapular notching in reverse total shoulder arthroplasty. METHODS: We retrospectively reviewed records of patients who had undergone reverse total shoulder arthroplasty by the senior author from July 2004 through October 2011 and who had at least 24 mo of follow-up. The 58 patients who met the criteria had 65 arthroplasties: 18 with a Grammont-type prosthesis (Grammont group) and 47 with a lateral-based prosthesis (lateral-design group)...

Long Chen, Fei Xing, Zhou Xiang
PURPOSE: Network meta-analysis (NMA) is a comparatively new evidence-based technique in medical disciplines which compares the relative benefits associated with multiple interventions and obtains hierarchies of these interventions for various treatment options. We evaluated the effectiveness and safety of open reduction and internal fixation (ORIF), hemiarthroplasty (HA), reverse shoulder arthroplasty (RSA), intramedullary nailing (IN) and non-operative treatment (NOT) of displaced proximal humeral fractures in adults using Bayesian NMA of data from clinical trials...

INTRODUCTION: The most frequent indications for anatomic shoulder replacement are glenohumeral osteoarthritis and fractures of the humeral head. If anatomic shoulder prostheses fail, reverse total shoulder arthroplasty is often the only remaining treatment option. This study evaluates the influence of indications for primary shoulder arthroplasty on the clinical outcome after conversion to reverse total shoulder arthroplasty. MATERIALS AND METHODS: From 2010 to 2012, 44 failed shoulder arthroplasties were converted to reverse total shoulder arthroplasty...

BACKGROUND: Reverse total shoulder arthroplasty (rTSA) has gained popularity in recent years, providing good shoulder elevation, yet less predictable rotations. Good rotations are crucial for performance of activities of daily living (ADLs), including personal hygiene. Concerns remain regarding bilateral rTSA over lack of rotations bilaterally and resultant difficulties with ADLs. This study examined the outcome of patients with bilateral rTSA in restoration of function and ADLs. METHODS: Data were prospectively collected for 19 patients (15 women, 4 men; 38 shoulders), with a mean age of 74...

There has been a rapid increase in the number of shoulder arthroplasties, including partial or complete humeral head resurfacing, hemiarthroplasty, total shoulder arthroplasty, and reverse total shoulder arthroplasty, performed in the United States over the past two decades. Imaging can play an important role in diagnosing the complications that can occur in the setting of these shoulder arthroplasties. This review is divided into two parts. The first part provides a general discussion of various imaging modalities, comprising radiography, CT, MRI, ultrasound, and nuclear medicine, and their role in providing useful, treatment-guiding information...

BACKGROUND: The purpose of this study was to examine the effect of smoking on the incidence of complications after primary anatomic total shoulder arthroplasty (TSA) and reverse shoulder arthroplasty (RSA). METHODS: All patients who underwent primary TSA or RSA at our institution between 2002 and 2011 and had a minimum 2-year follow-up were included. Smoking status was assessed at the time of surgery. Current smokers, former smokers, and nonsmokers were compared for periprosthetic infection, fractures (intraoperative and postoperative), and loosening after surgery...

BACKGROUND: Treating shoulders with osteoarthritis, an intact rotator cuff, and substantial glenoid bone loss is challenging. One option is reaming the glenoid flat and inserting a reverse prosthesis. This study reports the subjective, objective, and radiographic results of reverse total shoulder arthroplasty (RTSA) in this population. METHODS: We retrospectively reviewed 42 consecutive patients (23 women; mean age, 71 years [range, 53 to 89 years]) with primary glenohumeral osteoarthritis, intact rotator cuffs, and Walch type-A2 (n = 19), B2 (n = 5), or C glenoids (n = 18) who had undergone a total of 42 RTSAs with glenoid reaming without bone-grafting between 2008 and 2013 (mean follow-up, 36 months [range, 24 to 66 months])...

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...

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...

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...

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...
