Hip Fractures
Symptoms and Signs of Hip Fractures
Hip fractures most often result in groin pain and inability to ambulate. Sometimes pain is referred to the knee and is thus misinterpreted as a knee abnormality. Similarly, pubic ramus fractures can cause groin pain. Patients with displaced fractures cannot walk and have significant pain; the affected leg may appear shortened and externally rotated. In contrast, patients with impacted fractures may be able to walk and have only mild pain and no visible deformity. However, such patients are usually unable to flex the entire lower limb against resistance with the knee extended. Passive hip rotation with the knee flexed aggravates the pain, helping to distinguish hip fracture from extra-articular disorders such as trochanteric bursitis.
