Sport-specific performance factor profiling: fencing as a prototype.

A musculoskeletal profiling study was done on 24 members of the U. S. Pan American and Olympic fencing squads. This was presented as a methodological prototype for future, more comprehensive sport profiling studies. It is proposed that sport-specific profiling data have practical application in the following areas: 1. The identification of physical deficiencies in an athlete, using his or her sport profile as a comparative standard. This would apply to general pre- and postseason screening as well as to medical complaint-related examinations. 2. Providing objective, sport-specific criteria for determining when an injured athlete has recovered to the extent that he or she is adequately prepared to return to play. Rehabilitation goals for full recovery can also be defined. 3. Increasing the efficacy and efficiency of training techniques. 4. The prospective identification of superior performance potential in athletes at early competitive levels. If sport profiles were developed for the major participant sports at several competitive levels, the profiling system as described here could have significant application to a large number of athletes in a variety of playing situations.

Computed tomography (CT) arthrography of shoulder instabilities in athletes.

Sixty professional and recreational athletes underwent CT arthrography of the shoulder for evaluation of suspected shoulder joint derangement. These athletes, 46 males and 14 females ranging in age from 15 to 60 years (mean, 32 years), all had persistent pain that interfered with their sports activity and was resistant to conservative treatment. Seventeen patients had shoulder instability based on clinical manifestations and CT arthrographic findings. An additional five patients, also based on clinical manifestations and CT arthrographic findings, were considered to have an unobtrusive degree of anterior joint laxity. Patients with anterior instability (20 cases) all had an anteroinferior tear or detachment of the glenoid labrum, as well as some violation of the insertion of the joint capsule onto the scapula. Those with posterior instability (two cases) had a combination of labral and capsular tears. Two other major patterns of labral tears, both unaffiliated with shoulder instability, were identified. These included total or partial detachment of superior segments of the labrum, and anterior labral tears at the midglenoid level. Moreover, various degrees of labral attenuation (or, less often, enlargement), osteophyte formation, and alterations in articular cartilage were observed. Surgical correlation was obtained in 25 patients, with 95% accuracy of CT arthrographic findings. CT arthrography is a minimally invasive and highly accurate technique for investigation of glenohumeral derangement. Specifically, the extent of pathologic changes associated with instability can be determined and differentiated from other intraarticular causes of incapacity, such as labral tears caused by throwing, or degenerative changes.
