The utility of postconcussion neurocognitive testing versus symptom data has been debated. The sensitivity of the desktop version of the Immediate Post-concussion assessment and cognitive testing (ImPACT) tool has been documented, but psychometric properties of the recently released online version of ImPACT have yet to be fully established. ⋯ The online version of the ImPACT tool is a valid measure of neurocognitive performance at the acute stages of concussion, with high levels of sensitivity and specificity, even when athletes appear to be denying postconcussion symptoms.

Intra-articular hip injuries in national hockey league players: a descriptive epidemiological study.
Intra-articular hip injuries are thought to be common in professional ice hockey; however, injury incidence and missed playing time have not been previously documented. Furthermore, it is not known if injury incidence differs between player positions. ⋯ Hip labral tears are the most frequently encountered intra-articular hip injury in the NHL player and can lead to an average of 8 man-games missed per injury. Goaltenders were not at higher risk when measuring injuries per hours played but were at significantly greater risk of an intra-articular hip injury than other on-ice players (RR, 4.7) when measured per game played.

Muscle injury is the most common injury type in professional soccer players. Despite this, risk factors for common lower extremity injuries remain elusive. ⋯ Intrinsic factors found to increase muscle injury rates in professional soccer were previous injury, older age, and kicking leg. Injury rates varied during different parts of the season and also depending on match location.

Patients with chronic exertional compartment syndrome who have failed nonoperative treatment are evaluated with pre-exertion and postexertion compartment pressure testing and may be treated with fasciotomy. Failure rates of up to 20% have been reported and may be related to factors such as age, sex, postexertion compartment pressures, compartment(s) released, and duration of symptoms. ⋯ High school and college patients (age <23 years) and isolated anterior compartment release (compared with anterior/lateral release) were factors associated with improved subjective function and satisfaction after fasciotomy. We recommend the avoidance of lateral release unless symptoms or postexertion compartment pressures are clearly indicative of lateral compartment involvement.
