Femoroacetabular impingement causes groin pain and decreased athletic performance in active adults. This bony conflict may result in femoroacetabular subluxation if of sufficient magnitude. The ligamentum teres has recently been reported to be capable of withstanding tensile loads similar to that of the anterior cruciate ligament, and patents with(More)
Posterior shoulder instability with glenoid deficiency is a rare entity and its surgical treatment is challenging. Reconstructive techniques have focused on extra-articular structural bone transfer that obstructs humeral translation and thereby prevents glenohumeral dislocation. However, long-term results are not as promising. In this report, the authors(More)
Multidirectional shoulder instability is defined as symptomatic instability in two or more directions. Instability occurs when static and dynamic shoulder stabilizers become incompetent due to congenital or acquired means. Nonspecific activity-related pain and decreased athletic performance are common presenting complaints. Clinical suspicion for(More)
BACKGROUND Internal fixation is an accepted treatment for displaced fractures of the calcaneus. Operative intervention in older patients, however, is traditionally discouraged in the literature. The purpose of this study was to compare the outcomes of internal fixation of intra-articular fractures of the calcaneus on the basis of patient age. METHODS One(More)
BACKGROUND Radiographic measures of acetabular coverage are essential screening tools used to characterize bony structure contributing to femoroacetabular impingement (FAI). Small changes in pelvic tilt result in altered radiographic measures of acetabular coverage. Positional changes in pelvic tilt are known to occur between the supine and weightbearing(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)
PURPOSE The purpose of this study was to compare single-row (SR), extended double-row (DR), and augmented, extended double-row (aDR) rotator cuff repairs in a two-tendon, posterosuperior rotator cuff tear (RCT) model with intact rotator cuff tendons. METHODS RCTs were created and randomly assigned to SR, DR, or aDR repair (5 each) in 20 cadaveric shoulder(More)
BACKGROUND Van Neck disease (VND) is a benign skeletal abnormality of children involving a hyperostosis of the ischiopubic synchondrosis (IPS) seen on radiographs. Patients typically complain of vague groin or buttock pain. Few descriptions of this disorder exist and it easily can be mistaken for other entities, particularly osteomyelitis or tumor. It is(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)
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)
