Metal-on-metal hip resurfacing in osteonecrosis of the femoral.

Hip Resurfacing Arthroplasty in Treatment of Avascular Necrosis of the Femoral Head

Management of osteonecrosis of the hip with resurfacing arthroplasty seems to be effective in strictly-selected patients. The Birmingham Mid-Head Resection prosthesis has a femoral neck-preserving feature and is available in a ceramic-on-metal configuration.

The patients were qualified to hip resurfacing when the following criteria were met: Use of metal-on-metal total hip resurfacing for the treatment piekarw osteonecrosis of the femoral head.

Table 1 Ethiology of avascular necrosis. The patients were assessed clinically with use of the UCLA physical activity score, the mean preoperative score was 3. All operations were performed with the patient 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.

Abstract Background Hip resurfacing is a conservative type of total hip arthroplasty but its use is controversial, nfcrosis in patients pekara osteonecrosis. We believe that restrictive qualification criteria for hip resurfacing and the use of an anterolateral approach might be useful prognostic factors in our group.

In addition, the qualification criteria used in our study seem to be appropriate, but the limitations mentioned above are drawbacks of this work. Survival of Birmingham hip resurfacing in patients with femoral head osteonecrosis. Etiology of avascular necrosis of the femoral head is presented in Table 1. Statistical methods Statistical analysis was performed using Statistica 7.


Preoperative necrotic area extent was measured with using MRI scans and averaged J Bone Joint Surg Am. Osteonecrosis of the femoral head is caused by impaired vascular supply. Blood supply to the femoral head is much better preserved during an anterolateral approach [ 2627 ].

Primary total hip arthroplasty with a second-generation cementless total hip prosthesis in patients younger than fifty years of age. Resurfacing arthroplasty in osteonecrosis of the femoral head — minimum 3 years follow-up. Find all citations in this journal default.

Differences in ion release after ceramic-on-ceramic and metal-on-metal total hip replacement Medium-term follow-up. Abstract Hip necroxis is a conservative type of total hip arthroplasty but its use is controversial, especially in patients with osteonecrosis. All patients were necroeis clinically and radiologically before and 60 months after the operation.

An end-result study using a new method of result evaluation. Determining lesion size in osteonecrosis of the femoral head. Statistical analysis was performed using Statistica 7.

Because of relatively young age and high activity of the patients, the results of THR in this group of patients are not encouraging.

No implant migration was observed. Published online Jan Additionally, detection of axial collapse of femoral component was assessed with the use of the component-lateral cortex ratio the ratio of the prosthesis length to the length of prosthesis and the bone segment extending to the lateral femoral cortex, Figure 2A, 2B.


Received May 13; Accepted Jul 1. The Shapiro-Wilks test was used to evaluate whether individual datasets were consistent with a normal distribution: The angle between the necrotic fragment and head-neck junction was also evaluated in anteroposterior preoperative x-rays Figure 1C. Atrophy of the proximal part of the femur after total hip arthroplasty without cement.

Usually young, active people between 20 and 50 years of age are affected by the disease and their occupational and physical activity is substantially limited [ 1 — 3 ]. In our group, we did not observe complications requiring revision surgery. Septic loosening, subtrochanteric fracture, and acetabular fracture at time of primary surgery that did not heal were the reasons for the 3 remaining revisions.

There were 60 In the avascular necrosis group, neck fracture and aseptic loosening were the reasons. Assessing activity in joint replacement patients.

In both groups the results were good; however, in both groups 2 jcaek required revision surgeries.
