BACKGROUND Treatment of complex three and four-part proximal humeral fractures with hemiarthroplasty in elderly patients has yielded mixed clinical results. Reverse shoulder arthroplasty has emerged as a treatment option for comminuted proximal humeral fractures for these patients. The purpose of the study was to perform a prospective evaluation of patient outcomes comparing hemiarthroplasty an...

It has been shown that an original attitude in forward or backward inclination of the trunk is maintained at gait initiation and during locomotion, and that this affects lower limb loading patterns. However, no studies have shown the extent to which shoulder, thorax and pelvis three-dimensional kinematics are modified during gait due to this sagittal inclination attitude. Thirty young healthy v...

Background Antibiotic spacers in shoulder periprosthetic joint infection deliver antibiotics locally and provide temporary stability. The purpose of this study was to evaluate differences between stemmed and stemless spacers. Methods All spacers placed from 2011 to 2013 were identified. Stemless spacers were made by creating a spherical ball of cement placed in the joint space. Stemmed spacer...

BACKGROUND Poor freestyle stroke biomechanics is a suggested risk factor for shoulder pain and pathology, but this has not been proven in biomechanical or clinical studies. Furthermore, the prevalence of these theoretical errors has not been identified, which would help coaches, athletic trainers, and researchers determine the most appropriate errors to focus on and develop interventions. HYP...

Water polo is a high-intensity intermittent aquatic sport which places large physical demands on the participants[1] and involves repetitive physical motions that are common to swimming and baseball pitching.[2] Water polo consists of four quarters, where two teams of seven players per side attempt to score goals by throwing the ball into their opponents' goal. Water polo is played in a pool me...

Treatment of rotator cuff deficient shoulders continues to evolve. Reverse total shoulder arthroplasty has proven effective for restoring forward elevation and abduction in patients who suffer from pseudoparalysis secondary to rotator cuff insufficiency. Unfortunately, reverse total shoulder arthroplasty is less effective at restoring lost external rotation function in patients with deficient p...

BACKGROUND Clinical studies of shoulder dislocations typically include adult patients (>16 years of age). Only small case series of patients aged 10 to 16 years are available to guide management. PURPOSE Using a cohort of patients aged 10 to 16 years, this study sought to determine (1) the incidence density rate (IDR) of primary anterior shoulder dislocations requiring closed reduction (CR) a...
