Epidemiology of shoulder dislocations presenting to emergency departments in the United States.
The epidemiology of traumatic shoulder dislocations is poorly understood. The aim of the current study was to determine the incidence of shoulder dislocations presenting to hospital emergency departments in the United States and define demographic risk factors for these injuries. ⋯ The estimated incidence rate of shoulder dislocations in the United States is 23.9 per 100,000 person-years, which is approximately twice the previously reported value. A young age and male sex are risk factors for shoulder dislocation in the United States population.

Comparative StudyComparison of arthroscopic and open treatment of septic arthritis of the wrist. Surgical technique.
Open irrigation and débridement is the standard of treatment for septic arthritis of the wrist. Although isolated cases of arthroscopic irrigation and débridement have been reported, a comparison of arthroscopic and open techniques has not been performed, to our knowledge. The purpose of this study was to compare the two methods of management. ⋯ Arthroscopic irrigation and débridement is an effective treatment for patients with isolated septic arthritis of the wrist; these patients had fewer operations and a shorter hospital stay than did patients who had received open treatment. However, these benefits were not seen in patients with multiple sites of infection.

Outcome of lumbar arthrodesis in patients sixty-five years of age or older. Surgical technique.
The value of lumbar spine arthrodesis in older patients is not well documented. As most of the literature regarding lumbar arthrodesis in older patients has focused on the prevalence of complications, the purpose of this study was to determine the clinical outcomes for older compared with younger patients undergoing lumbar arthrodesis. ⋯ This study demonstrates a substantial benefit for patients sixty-five years of age or older with degenerative disc disease who are treated with a single-level lumbar decompression and instrumented arthrodesis, and we conclude that lumbar arthrodesis is a viable and reasonable treatment option for appropriately selected patients sixty-five years of age or older.

Multicenter StudyOperative management of distal radial fractures with 2.4-millimeter locking plates: a multicenter prospective case series. Surgical technique.
In the past decade, there has been a trend toward open reduction and internal fixation of unstable distal radial fractures. There are now more than thirty different implant designs specific for the fixation of distal radial fractures. A multicenter prospective study of a case series was conducted to determine the efficacy of the operative management of distal radial fractures stabilized with 2.4-mm locking plates. ⋯ Internal fixation of displaced distal radial fractures with implants featuring locking screw fixation can result in good-to-excellent outcomes with a limited number of complications.

Assessment of the posterior ligamentous complex following acute cervical spine trauma.
Magnetic resonance imaging is commonly used to assess the integrity of the posterior ligamentous complex following cervical trauma, but its accuracy and reliability have not been documented, to our knowledge. The purpose of this study was to determine the diagnostic accuracy of magnetic resonance imaging in detecting injury to specific components of the posterior ligamentous complex of the cervical spine. ⋯ Magnetic resonance imaging is sensitive for the evaluation of injury to the posterior ligamentous complex in the setting of acute cervical trauma. However, it has a lower positive predictive value and specificity, suggesting that injury to the posterior ligamentous complex may be "over-read" on magnetic resonance images. If magnetic resonance imaging is used in isolation to guide treatment, the high rate of false-positive findings may lead to unnecessary surgery. Other factors, including the morphology of the injury and the neurological status, should be considered as well when devising a treatment plan.
