Acetabulum malunions are extremely difficult to treat, and for many years, surgical indications have been dominated by total hip replacement. We treated a protruding acetabular malunion, 20 years ago, using an intra-articular buttress, by means of an allograft corresponding to a femoral head fragment which had been cryopreserved. The radiological and clinical result with this extended follow-up is quite remarkable, which has motivated us to present this original technique.

Resonance Frequencies

The major complications following total hip replacement (THA) are implant loosening, dislocation, instability, fracture and infection. It is hypothesized that vibration, in the range of the resonance frequencies, may cause pain, bone degeneration and fracture. A further understanding of the physical response resulting from impact during femoral head sliding may lead to valuable insight pertaining to THA failure. Therefore, the first objective of this present study was to determine if frequencies propagating through the hip joint near resonant frequencies may lead to wear or loosening of the components. Recently, studies found that femoral head sliding, often referred to as hip separation, between the acetabulum cup and the femoral head does occur, which may also play a role in complications observed with THA today, but a the effects of hip separation and the causes of its occurrence has not been studied as jet. Therefore, the second objective of this study was to determine if a sound sensor, externally attached, could be used to correlate impact loading sounds from femoral head sliding in the acetabular cup. Additional objective of this study was to develop a mathematical model that better simulates the in vivo loading conditions of total hip replacement patients using in vivo fluoroscopic and ground reaction data as input.

First Choice

Although there is no completely effective treatment for osteonecrosis (ON), core decompression is one of the more popular methods used to promote healing and retard progression. However, there has been considerable controversy about its safety and effectiveness. Published reports have indicated clinical success which has varied from 40 to 90 percent. We performed core decompression with supplementary cancellous bone grafting on 406 hips with ON. There were five complications in the entire series, including two hip fractures resulting from falls. Of 297 hips with a two to fourteen year follow-up, total hip replacement was required in only 36 percent of treated hips as compared to 77 percent of non-operated controls. The outcome was correlated with both the stage and the size of the necrotic lesion. Only 22 percent of the hips with small lesions required total hip replacement as compared to 39 percent with intermediate or large lesions. There was no correlation between outcome and the amount of pain present prior to surgery. Various modifications of core decompression have also been used to treat ON. These have included the use of supplementary grafts of various types, electrical stimulation, decalcified bone matrix, and bone morphogenic protein. Early results in limited series have been encouraging, but some of those techniques remain experimental. At the present time we feel that core decompression, with or without bone grafting, is a simple, safe, and established technique which is our first choice for the treatment of patients with earlier stages of ON. The role of vascularized fibular grafts is promising and the place of other new techniques is currently being evaluated.
