Abstract:

Aim: Patients with developmental dysplasia of the hip joint sooner or later develop secondary arthritis which turns them to become candidates for total hip arthroplasty surgery. Following surgery, some of them continue to limp, although they experience no pain. We try to offer a biomechanical explanation for persistent limping, and also provide theoretic possibilities to prevent or minimize it. Methods: In this article, we use our own method of assessment of hip biomechanics on normal and dislocated hip in female patient that has undergone total hip arthroplasty surgery on dislocated side. We used preoperative and postoperative pelvic radiographs on which we assessed biomechanical properties of both hip joints. Results: After total hip arthroplasty surgery, our patient has pain-free walk, but limping still exists, although smaller. Comparing biomechanical properties between healthy and dislocated and operated hips it can be seen that for biomechanical balance total loading would be about 70% bigger on operated side. Hip abductor muscles cannot give such power because of relative insufficiency, and limping still persists. Conclusion: This article, in a specific way, explains disadvantages of high positioned hip prosthesis on hip biomechanics and limping. Limping is caused by relative insufficiency of hip abductor muscles because of high position of the great trochanter, and also because of high position of the center of hip prosthesis. Orthopedic surgeon should exercise a caution when informing a patient about the outcome of the surgery, particularly about the limping. Knowledge of hip biomechanics is required in order to prevent false expectations and disappointments of both patient and surgeon.
