Introduction: Bony changes associated with FAI has been seen in asymptomatic athletes. These changes could lead to intra-articular damage of the hip.
Objective: To determine the prevalence of cam/pincer FAI and labral tears in elite volleyball players and determine factors associated with their presence.
Methods: 94 elite level volleyball players(ages 15 to 40; 26 females, 68 males ) underwent hip screening and ultrasound(US) examination All players were competitors in national or international competition and average years of competition was 13.76±6 years There were 26 blockers, 33 hitters, 17 setters and 18 others. All players had a clinical hip examination consisting of the FABER test, impingement testing, dial test, and range of motion measurements. An US examination of the hip was performed by a certified physician.
Results: Ten(11%) of the athletes reported prior hip injuries. Females had significantly more abduction(41 vs 38;p=0.02), adduction(41 vs 38;p< 0.01), extension(15 vs 13;p=0.036), external rotation (43 vs 38;p=0.004) and internal rotation (44 vs 34;p< 0.01). In addition, females were more likely to have a positive hip dial test(p=0.006). Of the 188 hips examined, cam was identified in 57(30%) hips, pincer in 42(22%)hips (1 hip had isolated pincer, 41 had combined cam/pincer) and labral tears in 45(24%) hips. Athletes with cam were significantly older (median=23 years) compared to athletes without cam(median=19)(p=0.041). There was no association between cam and gender, year played, or BMI. . Range of motion was not associated with presence of cam/pincer or labral tears on US. The presence of a labral tear was associated with cam(p< 0.001). Volleyball players with cam were 16 [95%CI:7 to 36] times more likely to have a labral tear. Setters were 3.1 [95%CI:1.2 to 8] times more likely than hitters to have a labral tear(p=0.025) and 3 [95%CI:1.1-8] time more likely than blockers to have a labral tear.
Conclusion: Elite level volleyball players report a low level of hip injuries; however, cam impingement was observed in 30% and labral tears in 24%. Range of motion was not associated with cam or labral tears, but does differ between gender. Position played also is related to increased risk of cam and labral tears. When developing further screening or prevention programs, gender and position should be considered in volleyball athletes.
