Clavicle fractures are common in adults and children. Most commonly, these fractures occur within the middle third of the clavicle and exhibit some degree of displacement. Whereas many midshaft clavicle fractures can be treated nonsurgically, recent evidence suggests that more severe fracture types exhibit higher rates of symptomatic nonunion or malunion.(More)
The aim of the study was to determine if the concept of face and construct validity may apply to the SurgicalSim Educational Platform (SEP) "robot" simulator. The SEP robot simulator is a virtual reality (VR) simulator aiming to train users on the Da Vinci Surgical System. To determine the SEP's face validity, two questionnaires were constructed. First, a(More)
PURPOSE To provide an overview of the characteristics and timing of rotator cuff healing and provide an update on treatments used in rehabilitation of rotator cuff repairs. The authors' protocol of choice, used within a large sports medicine rehabilitation center, is presented and the rationale behind its implementation is discussed. BACKGROUND If initial(More)
BACKGROUND The number of displaced midshaft clavicle fractures treated surgically is increasing, and open reduction and intramedullary fixation is an emerging surgical treatment option. The study quality and scientific levels of published evidence in which possible complications of this treatment are presented vary greatly. METHODS We performed systematic(More)
BACKGROUND Infections after shoulder surgery are potentially devastating complications. Propionibacterium acnes is recognized as a causal agent in shoulder infections. The clinical presentation is usually insidious and nonspecific, but a P. acnes infection could be an occult cause of postoperative shoulder pain. QUESTIONS/PURPOSES What are the clinical(More)
BACKGROUND The purposes of this study were to evaluate the association between the acromial index and full-thickness rotator cuffs and to determine if the size of the acromial index was associated with outcomes in a cohort of patients who had had arthroscopic repair of full-thickness rotator cuff tears. METHODS The acromial index was calculated for three(More)
PURPOSE The purpose of this study was to assess the efficacy of arthroscopic scapulothoracic bursectomy in patients with snapping scapula syndrome with a minimum of 2 years' follow-up. METHODS In this institutional review board-approved retrospective study, 23 shoulders in 21 consecutive patients were identified that had undergone arthroscopic treatment(More)
BACKGROUND Over the past decades, the operative treatment of displaced midshaft clavicular fractures has increased. The aim of this study was to compare short and midterm results of open reduction and plate fixation with those of intramedullary nailing for displaced midshaft clavicular fractures. METHODS A multicenter, randomized controlled trial was(More)
The management of osteoarthritis of the shoulder in young, active patients is a challenge, and the optimal treatment has yet to be completely established. Many of these patients wish to maintain a high level of activity, and arthroplasty may not be a practical treatment option. It is these patients who may be excellent candidates for joint-preservation(More)
The glenohumeral articulation is a versatile joint that requires a complex integration of bony ligamentous, musculotendinous, and neurovascular structures for proper function. Injuries resulting from dysfunction are common and potentially debilitating. Many of these injuries can be managed nonsurgically; however, if surgical treatment is indicated, a(More)
