: 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...

BACKGROUND: Shoulder arthroplasty is an effective procedure for managing patients with shoulder pain secondary to end-stage arthritis. Insurance status has been shown to be a predictor of patient morbidity and mortality. The current study evaluated the effect of patient insurance status on perioperative outcomes after shoulder replacement surgery. METHODS: Data between 2004 and 2011 were obtained from the Nationwide Inpatient Sample. Analysis included patients undergoing shoulder arthroplasty (partial, total, and reverse) procedures determined by International Classification of Disease, 9th Revision procedure codes...

BACKGROUND: Patients undergoing reverse total shoulder arthroplasty (RTSA) are at risk of significant perioperative blood loss. To date, few studies have examined the effectiveness of tranexamic acid (TXA) to reduce blood loss in the setting of RTSA. METHODS: In a prospective, double-blinded, single-surgeon trial, we analyzed 102 patients undergoing primary RTSA who were randomized to receive intravenous TXA (n = 53) or placebo (n = 49). Calculated total blood loss, drain output, and hemoglobin (Hb) drop were measured...

BACKGROUND: Long-term results and complication rates in shoulder arthroplasty are related to implant positioning. Current literature reports increased precision in glenoid component positioning using 3-dimensional (3D) computed tomography (CT) planning tools. This study evaluated the accuracy of glenoid version and inclination measurements using 2D CT scans compared with a validated 3D software program and its influence on decision making on implant selection. METHODS: Preoperative CT scans were obtained from 50 patients undergoing total shoulder arthroplasty...

BACKGROUND: Increased operative duration has been shown to have demonstrable effects on the outcomes and complications in multiple areas of orthopedic surgery. We sought to determine if patient- and surgeon-specific factors correlated to operative duration in shoulder arthroplasty. Our hypothesis was that increased surgeon and trainee volume would decrease operative times and that more complex pathology would increase operative duration. METHODS: A retrospective review of primary and revision total and reverse shoulder arthroplasties performed at a single institution from 2012 through 2015 was performed evaluating the correlation between specific patient and surgeon factors and operative duration...

Justin C Kennon, Caroline Lu, Meghan E McGee-Lawrence, Lynn A Crosby
BACKGROUND: Reverse total shoulder arthroplasty (RTSA) is a viable treatment option for rotator cuff tear arthropathy but carries a complication risk of scapular fracture. We hypothesized that using screws above the central glenoid axis for metaglene fixation creates a stress riser contributing to increased scapula fracture incidence. Clinical type III scapular fracture incidence was determined with screw placement correlation: superior screw vs. screws placed exclusively below the glenoid midpoint...

: Thumb carpometacarpal joint replacement is associated with high rates of loosening and failure. We present our results for an uncemented ceramic-ceramic total joint prosthesis with a reverse ball-and-socket design and bioactive coating. Between 2008 and 2012, 29 prostheses were inserted into 28 patients (mean age 63 years) with advanced osteoarthritis. After a mean period of 33 months (range 9-62), 26 patients (27 implants) were available for follow-up. Six months postoperatively, 50% of the patients had radiological evidence of early loosening...

BACKGROUND: Placement of the glenoid baseplate is of paramount importance for the outcome of anatomical and reverse total shoulder arthroplasty. However, the database around glenoid size is poor, particularly regarding small scapulae, for example, in women and smaller individuals, and is derived from different methodological approaches. In this multimodality cadaver study, we systematically examined the glenoid using morphological and 3D-CT measurements. METHODS: Measurements of the glenoid and drill hole tunnel length for superior baseplate screw placement were recorded to define size of the glenoid and the distance to the scapular notch on cadaveric specimens...
