BACKGROUND Little is known of the incidence of shoulder instability, despite some evidence that it may be a common injury in young, athletic individuals. The goal of this study was to determine the incidence of shoulder dislocation in United States military personnel, as well as to identify the demographic risk factors for injury. METHODS We performed a query of the Defense Medical Epidemiolo...

Volleyball has become an extremely popular participation sport worldwide. Fortunately, the incidence of serious injury is relatively low. The sport-specific activity most commonly associated with injury is blocking. Ankle sprains are the most common acute injury. Recurrent sprains may be less likely to occur if an ankle orthosis is worn. Patellar tendinitis represents the most common overuse in...

To reach the level of elite, most baseball pitchers need to consistently produce high ball velocity but avoid high joint loads at the shoulder and elbow that may lead to injury. This study examined the relationship between fastball velocity and variations in throwing mechanics within 19 baseball pitchers who were analyzed via 3-D high-speed motion analysis. Inclusion in the study required each ...

Anterior dislocation of the shoulder joint with ipsilateral humerus shaft fracture is a very rare injury. Until July 2006 only 18 cases have been reported in the literature. Here we report a case of Anterior Shoulder dislocation with greater tuberosity and shaft of humerus fracture. The patient was treated by Open reduction and internal fixation of the shaft fracture followed by closed reductio...

INTRODUCTION The purpose of this study is to analyze national and institutional trends in shoulder arthroplasty utilization by race. METHODS The Nationwide Inpatient Sample (NIS) was analyzed to determine racial trends in shoulder arthroplasty utilization nationally. An institutional database was then utilized to retrospectively identify all patients undergoing shoulder arthr...

BACKGROUND Generalized ligamentous laxity is defined as an increased range of joint motion compared to that of the general population. It is a predisposing factor for sports injuries, especially in the lower extremities. Nevertheless, there is little evidence about the relationship between generalized ligamentous laxity and sports injuries in the upper extremities. OBJECTIVES To evaluate the ...

PURPOSE To review the demographics and injury patterns in consecutive pediatric patients with traumatic brachial plexus injury presenting to a single center over a 16-year period and to review the outcomes of nerve grafting and nerve transfers for reconstruction of shoulder abduction and elbow flexion in these patients. METHODS Forty-five pediatric patients presented for treatment of traumati...

PURPOSE To determine whether transfer to only the anterior branch of the axillary nerve will restore useful function after axillary nerve injury with persistent posterior deltoid and teres minor paralysis. METHODS We used a computational musculoskeletal model of the upper limb to determine the relative contributions of posterior deltoid and teres minor to maximum joint moment generated during...

Background: The present study was aimed to evaluate the functional outcome and practical effectiveness of spinal accessory to suprascapular nerve transfer (XI-SSN) performed for restoration of shoulder reanimation. Methods: This was a prospective study conducted on 10 consecutive cases of brachial plexus injury during December 2010 to October 2011.The patients aged 16 to 47 years old (mean age ...

INTRODUCTION Traumatic anterior dislocation of the shoulder is an emergency and warrants urgent attention. However, it becomes difficult to manage in cases of associated fractures of humerus and other bones surrounding the shoulder joint. There have been reports of traumatic anterior dislocation of the shoulder associated with humeral fractures in the literature but the trilogy of anterior disl...
