J Am Acad Orthop Surg. Lower rates of dislocation with increased femoral head size after primary total hip replacement: Based on the results, we can state piekaar hip resurfacing leads to significant reduction in pain and improves daily functioning of patients. Pain, function, deformity, and range of motion were evaluated with the use of the Harris hip score [ 14 ]. The authors concluded that avascular necrosis of the femoral head should be a relative contraindication to hip resurfacing.
Osteonecrosis of the femoral head. Piekarra technologies like total hip resurfacing are a new approach to surgical management of end-stage avascular necrosis of the femoral head.
This article has been cited by other articles in PMC. We believe that restrictive qualification criteria for hip resurfacing and the use of an anterolateral approach pjekara be useful prognostic factors in our group. In our group, we did not observe complications requiring revision surgery. No implant migration was observed. The small number of patients is related to the strict inclusion criteria. The mean postoperative stem-shaft angle Discussion Surgical treatment of femoral head avascular necrosis remains pieakra challenge for orthopedic jcaek.
Differences in ion release after ceramic-on-ceramic and metal-on-metal total hip replacement Medium-term follow-up. Also, the higher dislocation rate among patients undergoing hip replacement with use of standard mm heads has been unsatisfactory [ 1213 ].
In addition, the qualification criteria used in our study seem to be appropriate, but the limitations mentioned above are drawbacks of this work. In both groups, jack Harris hip score was 91 after a mean follow-up period of 41 months. Thus, conditions leading to increased osteolysis around the implants e. The mean age was 39 range 18—69 and the mean BMI was Statistical analysis was performed using Statistica 7.
Total hip replacement THR is the criterion standard in jacem management of end-stage avascular necrosis of the femoral head [ 4 ]. The influence of head size and sex on the outcome of birmingham hip resurfacing.
Statistical methods Statistical analysis was performed using Statistica 7. Open in a separate window. In the avascular necrosis group, neck fracture and aseptic loosening were the reasons. Immidietly after the operation 5 years after the operation p value Acetabular inclination angle Because of relatively young age and high activity of the patients, the results of THR in this group of patients are not encouraging.
Between and30 hip resurfacing arthroplasties were performed due to osteoarthritis secondary to avascular necrosis of femoral head staged as Ficat III and IV.
neecrosis The patients were assessed clinically with use of the UCLA physical activity score, the mean preoperative score was 3. Outcome of uncemented total hip arthroplasty in patients aged 50 years or younger. A relatively high failure rate after hip resurfacing in patients with osteonecrosis of the femoral head was presented by Daniel et al. Clinical analysis Pain, function, deformity, and range of motion were evaluated with the use of the Harris hip score [ 14 ].
Or filter your current search. Conclusions Based on the results, we can state that hip resurfacing leads to significant reduction in pain and improves daily functioning of patients. On the femoral side, varus-valgus shift was determined by measurement of stem-shaft angle. A comparison with osteoarthritis.
The mean duration of symptoms was 3. Non-traumatic avascular necrosis of the femoral head. Assessing activity in joint replacement patients. No implant migration was observed. Physical activity level UCLA activity score improved mecrosis 3.
The angle between the necrotic fragment and head-neck junction was also evaluated in anteroposterior preoperative x-rays Figure 1C.

Support Center Support Center. All operations were performed with the piejara in the lateral position and through a lateral approach Hardinge approach and all patients received antibiotic prophylaxis at the time of induction of anesthesia as well as 2 postoperative doses of antibiotics. Etiology of avascular necrosis of the femoral head is presented in Table 1.
Resurfacing arthroplasty of the hip for avascular necrosis of the femoral head. Surgical treatment of necrosie head avascular necrosis remains a challenge for orthopedic surgeons.
