The authors describe a step-by-step technique for reverse total shoulder arthroplasty using arthrotomy via the enlarged transacromial superior approach. This technique seems ideal for reinsertion of the tuberosities and to ensure adequate postoperative tensional balance of the infraspinatus and the subscapularis, which is critical for the rotator cuffs to function properly and to achieve optima...

BACKGROUND The Nordic Arthroplasty Register Association was initiated in 2007, and several papers about hip and knee arthroplasty have been published. Inspired by this, we aimed to examine the feasibility of merging data from the Nordic national shoulder arthroplasty registries by defining a common minimal data set. METHODS A group of surgeons met in 2014 to discuss the feasibility of merging...

abstract  background: in the recent decade, many primary total knee arthroplasties have  been carried out in iran and the number of revision cases is expected to rise with the  aging population. the aim of this study was to report the outcome of revision surgery  in the country and make a comparison between the outcome of revision and that of  the primary arthroplasty.  methods: retrospectively...

BACKGROUND The treatment of comminuted proximal humerus fractures in older patients is challenging. Variable values of functional outcomes scores, ROMs, patient satisfaction, and bony healing have been reported with conventional techniques, including open reduction and internal fixation, percutaneous pinning, and hemiarthroplasty. Another alternative is reverse total shoulder arthroplasty, alth...

Successful total shoulder arthroplasty is, in part, dependent on anatomic reconstruction of the glenohumeral joint. The purpose of this study was to evaluate the post-operative anatomy of total shoulder arthroplasty with an anatomic implant design in patients with primary glenohumeral osteoarthritis and compare it to published normative anatomic measurements. Fifty-one patients (56 shoulders) w...

The risk of glenoid component failure has led us to explore nonprosthetic glenoid arthroplasty coupled with humeral hemiarthroplasty, the "ream and run" (R&R) procedure, for the management of glenohumeral arthritis in active patients. We hypothesized that patients having a R&R procedure would have outcomes comparable with those of similar patients having a total shoulder arthroplasty (TSA). A c...

BACKGROUND Examine 90-day postoperative mortality and its predictors following shoulder arthroplasty METHODS We identified vital status of all adults who underwent primary shoulder arthroplasty (Total shoulder arthroplasty (TSA) or humeral head replacement (HHR)) at the Mayo Clinic from 1976-2008, using the prospectively collected information from Total Joint Registry. We used univariate logi...

Shoulder arthroplasty is a demanding procedure with a known complication rate. Most complications are associated with the glenoid component, a fact that has stimulated investigation into that specific component of the implant. Avoiding glenoid component malposition is very important and is a key reason for recent developments in pre-operative planning and instrumentation to minimise risk.Patien...

The authors report on their experience in revision total shoulder arthroplasty using the Delta III shoulder prosthesis, a reversed constrained prosthesis which is known to give good functional results in the rotator cuff-deficient shoulder. It was implanted in patients with a failed total or hemishoulder prosthesis. The Constant-Murley score was used to assess the functional outcome. The prelim...
