Long-term outcomes of reverse shoulder arthroplasty versus nonoperative treatment for 3- or 4- part proximal humerus fractures in elderly patients: Results from a prior randomized clinical trial.

Background And Objectives: Proximal humerus fractures (PHFs) are among the most common fractures in elderly patients, yet there is insufficient evidence from randomized controlled trials (RCTs) to determine the most appropriate interventions for their management. This study presents the long-term results of the first prospective RCT comparing surgical treatment with reverse shoulder arthroplasty (RSA) versus nonoperative treatment in displaced PHFs in elderly patients.

Materials And Methods: Patients from a previously published RCT of 62 patients, in which RSA was compared with nonoperative treatment, were followed up long term.

Does fluoroscopy improve baseplate position compared to conventional technique in reverse shoulder arthroplasty? A preliminary study.

Background: Accurate placement of glenoid component in reverse shoulder arthroplasty remains a challenge for surgeons of all levels of expertise; however, no studies have evaluated the utility of fluoroscopy as a surgical assistance method.

Methods: Prospective comparative study of 33 patients undergoing primary reverse shoulder arthroplasty during a 12-month period. Fifteen patients had a baseplate placed using the conventional "free hand" technique (control group), and 18 patients using intraoperative fluoroscopy assistance group, in a case-control design.

Dislocation after reverse total shoulder arthroplasty using contemporary medialized modular systems. Can we still consider it such a frequent complication?

Introduction: Improvement in reverse total shoulder arthroplasty (RTSA) prosthesis and technique has reduced the initially high complication and revision rates associated with this implant. However, instability continues to be a leading cause of reoperation after RTSA, being related in previous studies with medialized designs. The aim of this study was to determine the dislocation rate with the employment of two medialized modular systems of RTSA in our institution.

Reverse shoulder arthroplasty versus nonoperative treatment for 3- or 4-part proximal humeral fractures in elderly patients: a prospective randomized controlled trial.

Background: Proximal humeral fractures (PHFs) are among the most common fractures in elderly patients, but there is insufficient evidence from randomized controlled trials (RCTs) to determine which interventions are the most appropriate for their management. To date, no RCT has directly compared reverse shoulder arthroplasty (RSA) with nonoperative treatment for 3- or 4-part PHFs in elderly patients.

Methods: This was a prospective RCT.

Reverse total shoulder arhroplasty for the treatment of failed fixation in proximal humeral fractures.

Background: This study evaluates the clinical outcomes in patients with proximal humerus fractures (PHF) treated with reverse total shoulder arthroplasty (RTSA) as a revision procedure for failed fixation that have more than 5 years of follow-up.

Materials And Methods: This is a retrospective study of 270 RTSA. The inclusion criteria for this study consisted of patients initially treated with either open reduction and plate fixation (ORIF) or fixation using an intramedullary nail (IMN), who were managed with a single-stage revision to a RTSA, and had a minimum of 24 months clinical and radiological follow-up.
