According to recently published data, hip internal rotation during skating deceleration is likely the cause of femoroacetabular impingement being more common in ice hockey goaltenders than other athletes.
Researchers evaluated skating, butterfly save and recovery movements on the ice from 14 professional and collegiate goaltenders. Comparisons were made regarding hip mechanics between all three movements and how those movements relate to femoroacetabular impingement (FAI).
Goaltenders decelerating during skating exhibited a magnitude of peak hip internal rotation that was 54% greater than when in butterfly save motion and 265% greater than when in recovery motion.
Overall, only internal rotation was the only hip motion researchers observed to come close to terminal.
As a result of this data, the researchers believe repetitive end-range hip internal rotation is likely the primary precursor to, and likely catalyst for the high occurrence of, FAI in this athlete population. – by Christian Ingram
