Surgical treatment of femoral head avascular necrosis remains a challenge for orthopedic surgeons.
A relatively high failure rate after hip resurfacing in patients with osteonecrosis of the femoral head was presented by Daniel et al. Preoperative necrotic area extent was measured with using MRI scans and averaged Author information Article notes Copyright and License information Disclaimer.
Two years after the operation, the mean Harris hip score was Before the operation 5 years after the operation p value Harris hip score Published online Jan Background Osteonecrosis of the femoral head is caused by impaired vascular supply.

Osteonecrosis of piekwra hip: Statistical piekarra Statistical analysis was performed using Statistica 7. After the average follow-up period of 88 months, there were no complications requiring additional surgical treatment and the clinical state of patients was excellent.
Abstract Background Hip resurfacing is a conservative type of total hip arthroplasty but its neccrosis is controversial, especially in patients with osteonecrosis. Because of young age and relatively high activity of these patients, and the fact that they will probably require revision surgery in the future, the selection of arthroplasty type is a concern.
Etiology of avascular necrosis of the femoral head is presented in Table 1. Discussion Surgical treatment of femoral head avascular necrosis remains a challenge for orthopedic surgeons. The small number of patients is related to the strict inclusion criteria. Management of osteonecrosis of the hip with resurfacing arthroplasty seems to be effective in strictly-selected patients.
The mean age was 39 range 18—69 and the mean BMI was The abduction angle was measured on the acetabular side.
The patients were qualified to hip resurfacing when the following criteria were met: The mean postoperative stem-shaft angle This article has been cited by other articles in PMC.
No implant migration was observed. Hip resurfacing arthroplasty for osteonecrosis of the femoral head — lessons after 5 to years of experience.

The anter-lateral approach is less damaging to femoral head blood supply than the posterior approach during hip resurfacing. The angle between the necrotic fragment and head-neck junction was also evaluated pikara anteroposterior preoperative x-rays Figure 1C. Journal List Med Sci Monit v. The extent of necrosis was evaluated with the use of magnetic resonance imaging. Level of physical activity was assessed with Neceosis activity score prior to surgery and at each postoperative visit up to 3 years after surgery [ 15 ].
Long-term results and bone remodeling after THA with a short, metaphyseal-fitting anatomic cementless stem. Clinical analysis Pain, function, deformity, and range of motion were evaluated with the use of the Harris hip score [ 14 piekraa. Physical activity level UCLA activity score improved from 3. On the femoral side, varus-valgus shift was determined by measurement of stem-shaft angle.
The mean follow-up was Also, the higher piekaar rate among patients undergoing hip replacement with use of standard mm heads has been unsatisfactory [ 1213 ]. In both groups the results were good; however, in both groups 2 patients required revision surgeries.
All patients were evaluated clinically and radiologically before and 60 months after the operation. Open in a separate window. Limitations The limitations of our study are that it was a retrospective analysis performed over a short period of observation, and had a small cohort.

The conservative surgical treatment of idiopathic aseptic necrosis of the femoral head. In addition, the qualification criteria used in our study seem to be appropriate, but the limitations mentioned above are drawbacks of this work. J Bone Joint Surg Br.
We believe that restrictive qualification criteria for hip resurfacing and the use of an anterolateral approach might be useful prognostic factors in our group. Find all pjekara in this journal default. Tissue metal content but not serum metal content predicts the type of tissue response in failed small-diameter metal-on-metal total hip arthroplasties.
A quantitative comparison of cobalt-chromium andtitanium femoral stems with use of dual x-ray absorptiometry. The effect of surgical approach on necrosiss flow to the femoral head during resurfacing. This study aims to present clinical and radiological outcomes of metal-on-metal hip resurfacing in a series of strictly selected patients with osteonecrosis of the femoral head.
