: Is reverse total shoulder arthroplasty a feasible treatment option for failed shoulder arthroplasty? A retrospective study of 44 cases with special regards to stemless and stemmed primary implants. BACKGROUND: Due to humeral or glenoid bone-loss and rotator cuff insufficiency reverse total shoulder arthroplasty often means the only remaining treatment option in revision shoulder arthroplasty. This study investigates the clinical outcome of patients treated with a reverse total shoulder in revision cases with special regard to stemless and stemmed primary implants...

The rotator cuff (RC) insertions according to most anatomical texts are described as being separate from one another. However, clear fusion of the RC tendon fibres exists with prior studies showing this interdigitation forming a common, continuous insertion onto and around the lesser and greater tubercles (LT and GT) of the humerus. Current surgical repair methods (especially arthroscopic techniques) rarely mention or consider these connections during repair and suture anchor implantation. The general principles of RC surgery remain a controversial subject, due to various available techniques, surgeon experience and preference, and the contradicting success rates...

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...

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: 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 AND PURPOSE: Rupture of the anterior and middle deltoid muscle associated with rotator cuff tear arthropathy (RCA) could result in a definitive loss of shoulder function. The purpose of this study was to evaluate clinical outcomes after a concomitant reverse shoulder arthroplasty (RSA) and deltoid repair under these circumstances. MATERIALS AND METHODS: Between 2006 and 2012, 18 consecutive patients with a mean age of 69.7 years, affected by massive irreparable rotator cuff tear and associated dehiscence or rupture of anterior and middle deltoid muscle underwent this operation through a modified anterosuperior approach...

BACKGROUND: In selected patients with a desire to maintain activity levels greater than those recommended after reverse total shoulder arthroplasty, hemiarthroplasty remains an option for treatment of cuff tear arthropathy (CTA). However, given the relatively small case series that have been reported to date, little is known regarding which patients will show functional improvement after this surgery. QUESTIONS/PURPOSES: We asked: What factors are associated with achieving the minimum clinically important difference in the simple shoulder test (SST) after hemiarthroplasty for cuff tear arthropathy? PATIENTS AND METHODS: Between 1991 and 2007, two surgeons at one academic center performed 48 shoulder hemiarthroplasties for CTA...

BACKGROUND: Reverse total shoulder arthroplasty (RTSA) has classically been reserved for patients older than 65 years with rotator cuff arthropathy, pseudoparalysis, and severe pain. This investigation assessed outcomes in a consecutive series of patients aged 65 and younger undergoing primary RTSA. METHODS: There were 63 patients (67 shoulders; 40 women, 27 men) with a mean age of 60 years (range, 50-65 years). Indications were cuff tear arthropathy (CTA) in 51, severe glenohumeral arthritis in 15, and osteonecrosis in 1...

BACKGROUND: The American Shoulder and Elbow Surgeons (ASES) questionnaire was developed to provide a standardized method for evaluating shoulder function. Previous studies have determined the clinical responsiveness of this outcome measure for heterogenous populations or patients with nonoperatively treated rotator cuff disease. Currently, to our knowledge, no studies exist that establish the clinically relevant change in the ASES score after shoulder arthroplasty. QUESTIONS/PURPOSES: We asked: (1) What are the minimal clinically important difference (MCID) and substantial clinical benefit (SCB) for the ASES score after primary and reverse shoulder arthroplasties? (2) Are the MCID and SCB for the ASES score different between primary and reverse shoulder arthroplasties? (3) What patient-related factors are associated with achieving the MCID and SCB after total shoulder arthroplasty and reverse shoulder arthroplasty? METHODS: A longitudinally maintained institutional shoulder arthroplasty registry was retrospectively queried for patients who underwent primary shoulder arthroplasty, including anatomic or reverse total shoulder arthroplasty from 2007 to 2013, with a minimum 2-year followup...

Reverse total shoulder arthroplasty (TSA) is a useful intervention for older patients with glenohumeral arthritis and a deficient rotator cuff. However, as a semiconstrained prosthesis, conventional reverse TSA implanted in a young patient could fail over time secondary to polyethylene wear and subsequent osteolysis. A metal-on-metal prosthesis may avoid this type of failure. The purpose of this study is to assess the outcomes in an initial cohort of young patients who underwent reverse TSA using a metal-on-metal prosthesis...

The potential adverse effect of body mass index (BMI) on shoulder function scores after reverse shoulder arthroplasty (RSA) has not been investigated. We conducted a study to examine outcomes of RSA performed for rotator cuff tear arthropathy (RCTA) across BMI categories (normal weight, overweight, obese). We hypothesized that, compared with normal-weight patients, obese patients would have worse shoulder function scores, worse mobility, and more complications. Using a prospective shoulder arthroplasty registry, we identified 77 primary RSAs performed for RCTA with minimum 2-year follow-up...

Reverse total shoulder arthroplasty (RTSA) is a treatment option for patients with rotator cuff tear arthropathy, pseudoparalysis, and a functional deltoid. Our hypothesis was that no significant difference in postoperative active range of motion (ROM) will be observed in patients with 135° and 155° humeral cup inclination. A systematic review was registered with PROSPERO and performed with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies evaluating RTSA that reported the type of prosthesis as well as active postoperative ROM were eligible for inclusion...

The number of cases with rheumatoid arthritis who requires arthroscopic synovectomy is declining, but it is still a useful procedure in combination with effective pharmacologic disease control. For the destruction of glenohumeral joint, total shoulder arthroplasty is effective for pain relief and functional outcome for patients without rotator cuff impairment. The reverse shoulder arthroplasty has been shown favorable short-term results, but need a careful indication for rheumatoid shoulder with poor bone stock and bone quality...

BACKGROUND: This study compared the incidence and pattern of potential nerve injuries between reverse shoulder (RSA) and total shoulder arthroplasty (TSA) using intraoperative neuromonitoring. Our hypothesis was that RSA has a greater risk of nerve injury than TSA due to arm lengthening. METHODS: We reviewed 36 consecutive patients who underwent RSA (n = 12) or TSA (n = 24) with intraoperative neuromonitoring. The number of nerve alerts was recorded for each stage of surgery...
