Conclusions Management of osteonecrosis of the hip with resurfacing arthroplasty seems to be effective in strictly-selected patients.
The radiographic analysis showed no component migration or collapse. Preoperative necrotic area extent was measured with using MRI scans and averaged The mean age was 39 range 18—69 and the mean BMI was Long-term results and bone remodeling after THA with a short, metaphyseal-fitting anatomic cementless stem.
The abduction angle was measured on the acetabular side.
Hip Resurfacing Arthroplasty in Treatment of Avascular Necrosis of the Femoral Head
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. Support Center Support Center.
Atrophy of the proximal part of the femur after jacem hip arthroplasty without cement. Especially, the use of cemented hip endoprostheses results in high rate of revision surgeries [ 56 ].
A Hip resurfacing; inclination angle, component-lateral cortex ratio, B Hip resurfacing; stem shaft angle. The mean age and BMI of the patients were Etiology of avascular necrosis of the femoral head is presented in Table 1.
Apart from good clinical and functional results, they reported no cases of aseptic loosening. 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. 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.
In our study, necrosis was determined by x-ray, which is less precise but more available. Hip resurfacing is a conservative type of total hip arthroplasty but its use is controversial, especially in patients with osteonecrosis.

Metal ion levels in the blood of patients after hip resurfacing: Read Article at publisher’s site. There was no dislocation of the prosthesis in our group. This article has been cited by other articles in PMC. Immidietly after the operation 5 years after the operation p value Acetabular inclination angle J Am Acad Orthop Surg.
New technologies like total hip jzcek are a new approach to surgical management of end-stage avascular necrosis of the femoral head. The mean follow-up was The mean duration of symptoms was 3. In both groups the results were good; however, in both groups 2 patients required revision surgeries.
Management in the Twenty-first Century. Table 3 Necrosi results, component alignment. Articles from Medical Science Monitor: On the femoral side, varus-valgus shift was determined by measurement of stem-shaft angle.
Component migration was assessed by measuring inclination angle, femoral-stem angle, and component-lateral cortex ratio. Primary total hip arthroplasty with a second-generation cementless total hip prosthesis in patients younger than fifty years of age. Differences in ion release after ceramic-on-ceramic and metal-on-metal total hip replacement Medium-term follow-up.
