Type of Turnout and Injury Rates in Elite Dancers: A Critically Appraised Topic.

Abstract

Dancers commonly stand in hip external rotation due to the esthetics that ballet requires. Increased external rotation is desired which leads dancers to find ways to compensate to increase their external rotation, an action known as compensated turnout. Dancers commonly rotate at the tibiofemoral joint and/or the talocrural joint to increase external rotation of the entire lower body, placing increased stress on these joints. This critically appraised topic focuses on the relationship between types of turn out and lower-extremity injury in dancers. In elite dancers, does compensated, anatomical, or functional turnout influence lower-extremity injuries? Three studies met the inclusion criteria and were included in the analysis. One study demonstrated a relationship between compensated turnout and traumatic injuries, low back pain, and number of injuries in modern dancers. Greater compensated turnout in dancers was associated with a greater number of injuries. Two studies showed no relationship between anatomical or functional turnout and injuries in dancers. Based on 3 level 2b studies, there is level C evidence to suggest that increased compensated turnout is associated with increased traumatic lower-extremity injuries, low back pain, and number of injuries in university modern dancers compared with dancers with a reduced angle of compensated turnout. This relationship was not found between anatomical or functional turnout and lower-extremity injuries in elite dancers. There is weak evidence to suggest that compensated turnout, but not anatomical or functional turnout, is related to lower-extremity musculoskeletal injury. More research is needed to study compensatory mechanisms in a broader range of dancers and the relationship to lower-extremity injury.
