ReviewMicrobiology and Antimicrobial Challenges of Prosthetic Joint Infection.
Research that leads to better strategies to diagnose and treat prosthetic joint infection (PJI) is critical because PJI is a devastating complication of total knee arthroplasty. A key to the diagnosis and management of PJI is defining the microbiology of PJI and improving the medical management of PJI utilizing both systemic and local antimicrobial therapy. ⋯ This paper summarizes a presentation given at a recent multidisciplinary research conference entitled "Strategies to improve total knee arthroplasty" sponsored by the Knee Society. It was a part of a session entitled "Periprosthetic Joint Infection."

The Effect of Cervical Interbody Cage Morphology, Material Composition, and Substrate Density on Cage Subsidence.
Interbody cages used in spinal fusion surgery can subside into the adjacent vertebral bodies after implantation, leading to loss of spinal height, malalignment, and possible radicular symptoms. Several factors may contribute to cage subsidence. ⋯ Ranking of the relative impact of these factors indicated that substrate density had the greatest contribution to the measured subsidence (approximately 1.7 times and approximately 67 times greater than the contributions of cage footprint area and material, respectively). The contribution of cage footprint area to subsidence was found to be 40 times greater than the contribution of cage material to subsidence.

Orthopaedic Surgery Residency: Perspectives of Applicants and Program Directors on Medical Student Away Rotations.
Senior medical students frequently rotate at orthopaedic residency programs away from their home medical schools. However, to our knowledge, the perspective of program directors (PDs) and applicants on the value, objectives, and costs of these rotations has not been studied. ⋯ V.

ReviewDiagnosis, Treatment, and Return to Play for Four Common Sports Injuries of the Hand and Wrist.
Hand and wrist injuries in the high-level athlete are challenging because they may be underestimated by the patient, family, and team, and return to play may be longer than desired. The needs of the player and the team must be balanced with the long-term functional ramifications of the injury. Four common soft-tissue sports injuries are flexor digitorum profundus avulsion, flexor pulley rupture, extensor carpi ulnaris dislocation, and thumb metacarpophalangeal joint ulnar collateral ligament injury. For each of these injuries, the assessment, treatment, and considerations for return to play should be individualized on the basis of the patient, the sport, and the timing of the injury.

A concussion is a relatively common sports-related injury that affects athletes of all ages. Although orthopaedic surgeons are not expected to replace sports medicine physicians and neurologists with regard to the management of concussions, orthopaedic surgeons, particularly those who are fellowship-trained in sports medicine, must have a current knowledge base of what a concussion is, how a concussion is diagnosed, and how a concussion should be managed. Orthopaedic surgeons should understand the pathophysiology, assessment, and management of concussion so that they have a basic comprehension of this injury, which is at the forefront of the academic literature and North American media. This understanding will prepare orthopaedic surgeons to work in concert with and assist sports medicine physicians, athletic trainers, and physical therapists in providing comprehensive care for athletes with a concussion.
