Currently the availability of magnetic resonance imaging has replaced much of the arthrotomography and CT scanning. The increased soft tissue contrast provided by MRI allows its use in assessing tendinous, ligamentous, cartilaginous, and in particular subtle bone marrow changes, which before its inception were never directly imaged. ⋯ The sports medicine clinician's understanding of these changes as well as the new imaging modalities available to them are of paramount importance in treating today's athlete. Modalities available in the 1970s and 1980s were usually limited to plain radiographs to be followed by bone scanning, arthrotomography, or CT scanning.

Head and face injuries in scholastic women's lacrosse with and without eyewear.
The use of protective equipment has been absent or inconsistent in scholastic women's lacrosse leading to increasing concern for eye and head injury. There is a paucity of field data, however, on which to base strategic decisions on how best to prevent head injuries in young athletes. ⋯ On balance, then, the use of eyewear in women's lacrosse appears to be beneficial when users are compared with nonusers.

Laxity, instability, and functional outcome after ACL injury: copers versus noncopers.
The purpose of this study was to determine the relationship among laxity, quadriceps strength, instability, and function in subjects with complete rupture of the anterior cruciate ligament (ACL) who compensate well for the injury (copers) and those who require surgical stabilization (noncopers). ⋯ Copers were not different in any meaningful way from the noncopers before injury, had equal or greater side-to-side laxity differences, and functioned normally. A battery of tests was identified that accurately discriminated noncopers from copers even early after injury. Thus, measurements of laxity alone are insufficient for determining functional status after ACL injury.

Randomized Controlled Trial Clinical TrialNaproxen does not alter indices of muscle damage in resistance-exercise trained men.
Unaccustomed exercise is associated with an elevated plasma creatine kinase (CK), myofibrillar inflammation, and delayed onset muscle soreness (DOMS). Nonsteroidal antiinflammatory drugs (NSAID) may attenuate DOMS and indirect indices of inflammation in humans. ⋯ NSAID administration did not alter CK rise, muscle force deficit at 24 h postexercise, nor perceived muscle pain. In addition, the increased CK at 24 h postexercise was not associated with an acute myofibrillar inflammatory cell infiltrate in moderately trained men after resistance exercise.

Case ReportsBacterial osteitis pubis in a weight lifter without invasive trauma.
Osteitis pubis is a well-known complication of invasive procedures about the pelvis which is caused by a bacterial infection. It is also now known that osteitis pubis in athletes is an inflammatory disorder rather than infectious as previously thought. It occurs in athletes who place significant repetitive stresses across the symphysis in such activities as running, race walking, gymnastics, soccer, rugby, basketball, and tennis. ⋯ He was treated conservatively with intravenous antibiotics and physical therapy. At 3 months follow-up he had returned to his usual fitness activities without limitations. Although most osteitis pubis in athletes is inflammatory in nature, health care providers must keep an index of suspicion that an infectious etiology is possible in this population even without invasive trauma.
