Fractures of the acetabulum are challenging orthopedic injuries to repair, at times leaving multiple small fragments of fractured bone and cartilage. Compounded by the location in a region challenging in which to work and fraught with risk, these "puzzle pieces" must be brought back together to restore hip function and mobility.
Relative to hip fracture, acetabular fracture is uncommon. These fractures occur in two distinct patient populations:
In younger patients, high-energy injuries cause the break, such as motor vehicle or bike accidents, or falls from significant height.
In older patients with osteoporosis, low-energy injuries such as falls from standing height prompt the fracture.
