The anatomy of the hip and pelvis varies considerably in females compared to males. Many of these differences exist in order to allow for pregnancy and childbirth in women, while others are likely related to multiple factors. Some of these differences include:
Broader and shallower pelvis with circular inlet
Smaller femoral head with decreased surface area
Increased acetabular dysplasia (shallow sockets)
Increased femoral and acetabular anteversion (rotation)
Increased risk for low bone mineral density
Hypermobility
Other hormonal influences
Additionally, female athletes exhibit differences in biomechanics and sport-specific movements compared to male athletes, including:
Increased dynamic malalignment (see image)
Reduced core and gluteal strength
Increased asymmetry in lower extremity strength and biomechanics
Altered neuromuscular control
As a result of these differences, certain injuries to the hip joint and surrounding soft tissue structures are more common in female compared to male athletes, such as:
Hip/acetabular labral tears
Bone stress injuries/stress fractures in the hip and pelvis
Hip flexor, gluteal tendon, and high hamstring tendon dysfunction & pain
Quadriceps injury
Various impingement syndromes & nerve entrapments
Bottom line:
Unique differences in hip region anatomy and biomechanics result in a predisposition for specific injuries in female athletes
Consideration of these factors is important—not only for injury diagnosis—but for optimizing treatment, injury prevention, and performance
