BACKGROUND After severe brachial palsy involving the shoulder, many different muscle transfers have been advocated to restore movement and stability of the shoulder. Paralysis of the deltoid and supraspinatus muscles can be treated by transfer of the trapezius. METHODS We treated 10 patients, 8 males and 2 females, by transfer of the trapezius to the proximal humerus. In 6 patients the C5 and...

BACKGROUND Little is known about the incidence and characteristics of primary, or external, shoulder impingement in an occupationally and physically active population. A longitudinal, prospective epidemiologic database was used to determine the incidence and risk factors for shoulder subacromial impingement in the United States (U.S.) military. Our hypothesis was that shoulder impingement is in...

INTRODUCTION Extended manual wheelchair use has been associated with repetitive strain injuries in the shoulder and has been identified as a contributing factor to upper limb pain experienced by manual wheelchair users with spinal cord injury (SCI) [1]. Due to the nature of their SCI, individuals with tetraplegia (formerly quadriplegia) may be at an even greater risk for developing shoulder inj...

Although often perceived as a leisurely activity, golf can be a demanding sport, which can result in injury, usually from overuse and sometimes from poor technique. The shoulder is a commonly affected site, with the lead shoulder, or the left shoulder in the right-handed golfer, particularly vulnerable to injury. A thorough understanding of the biomechanics of the golf swing is helpful in diagn...

BACKGROUND Surgical simulation has become increasingly relevant to orthopaedic surgery education and could translate to improved operating room proficiency in orthopaedic surgery trainees. PURPOSE To compare the arthroscopic performance of junior orthopaedic surgery residents who received training with a knee and shoulder arthroscopy surgical simulator with those who received didactic trainin...

OBJECTIVES (1) To analyze the birth weight of obstetric brachial plexus injury (OBPI) patients requiring one or more reconstructive surgeries and (2) to analyze whether there is any difference in the severity of the injury, and the outcome of the surgery between the macrosomic and nonmacrosomic OBPI patients. STUDY DESIGN An observational cohort study was performed on 100 consecutive patients...

The occurrence of lateral capsular disruption as a cause of anterior shoulder instability has been reported previously. 1 It was suggested that this injury be considered in patients with instability and no injury or a minimal injury to the glenoid labrum. We now report the occurrence of lateral capsular disruption of the posterior aspect of the shoulder as a cause of pain and weakness. This Les...

CONTEXT The overhand pitch is one of the fastest known human motions and places enormous forces and torques on the upper extremity. Shoulder and elbow pain and injury are common in high-level pitchers. A large body of research has been conducted to understand the pitching motion. EVIDENCE ACQUISITION A comprehensive review of the literature was performed to gain a full understanding of all cu...
