Review of acetabular labral tears in dancers.

Over the past decade numerous articles have been published regarding the hip labrum. Injuries to the labrum are becoming better understood as biomechanical, kinematic, and diagnostic technologies improve. When the last article on acetabular labral tears appeared in the Journal of Dance Medicine and Science in 2006, this injury was widely handled surgically by debridement. Just 5 years later, we see a shift toward preservation and repair of the labrum and correction of morphology when possible. This change in philosophy has come about as new information on the function of the labrum and the stresses placed upon it at extremes of hip range of motion became available. It is now felt that an intact labrum is useful for preserving the hip's articular cartilage. The change in surgical technique has also necessitated a change in rehabilitation protocols focused on protecting the healing labrum and chondral surface. The vast majority of research available for analysis has not been addressed specifically to a dance population, yet most is relevant and helpful in determining better treatment for dancers. This article reviews the latest available data on labral function, stresses on the labrum resulting from dance, clinical and diagnostic detection of labral tears, and outcomes of labral tear treatment in the young athletic population, including dancers. Recommendations are offered to improve data collection and focus for future research.
