Hip resurfacing after failed free vascularized fibular graft

Metal-on-metal resurfacing of the hip is a bone sparing arthroplasty that may be an option when a head-sparing nonarthroplasty option fails. We present the first published report of 5 cases of failed free vascularized fibular graft treated with modern hip resurfacing arthroplasty. This selected group of patients had avascular necrosis with less than 20% head involvement and cysts less than 1 cm in diameter. Follow-up ranging from 2 to 5 years (mean, 38 months) showed improvement in hip function without evidence of prosthesis loosening. There were no femoral neck fractures or revisions. A vascularized fibular bone graft does not prevent good early results with hip resurfacing but may add technical complexity owing to its position within the femoral head and neck.

Free iliac crest grafts with periosteum for treatment of old acetabular defects

Objective: To inquire into the therapeutic effectiveness of free iliac crest grafts with periosteum on old acetabular defects. Methods:From February 1996 to June 2005, 9 patients were treated with free iliac crest grafts with periosteum to reconstruct old acetabular defects. There were 7 males and 2 females and the average age was 41.3 years. The acetabular defects were caused by traffic accidents in 6 cases and fall injury in 3 cases. The time from injury to treatment was 4-13 months and averaged 8 months. Intraoperatively we firstly removed the acetabular fracture fragments of the posterior wall. The femoral head was then reducted. Bone graft was harvested from the iliac crest with periosteum,which was sculpted with a rongeur to conform to the defect. The concave (iliac fossa) side of the graft was placed toward the femoral head. The graft was securedly fixed by two to three leg screws. Results:Postoperative syndrome was not found in any of the cases. Harris' score system showed that the score raised from 32. 3 points preoperatively to 81 points postoperatively. The hip function was evaluated as excellent in 3 cases,good in 4 cases and fair in 2 cases. Conclusions: Although this procedure could not exactly reproduce the anatomy of the hip joint, it enables to restore the posterior stability, provide bone-stock for the hip joints and prevent dislocation of the femoral head.     

应用吻合血管的游离腓骨移植治疗陈旧性股骨颈骨折

目的 对股骨颈骨折内固定失败和骨不连采用吻合血管的游离腓骨移植术治疗并进行临床评价。方法 对自2000年11月～2003年10月，采用吻合血管的游离腓骨移植术治疗的9例股骨颈骨折骨不连伴早期股骨头坏死的病例进行随访，平均随访时间22．5月。结果 9例骨折均获愈合，骨折愈合时间4～6月。在X线片上，所有病例的股骨头骨密度都表现明显增高，未见股骨头坏死加重的表现。Harris评分89．2分。结论 吻合血管的游离腓骨移植术是治疗股骨颈骨折内固定失败伴早期股骨头坏死的有效方法。     

Heterotopic ossification after treatment of femoral head osteonecrosis with free vascularized fibular graft

This study evaluated patients with heterotopic ossification after implantation of a free vascularized fibular graft for the treatment of femoral head osteonecrosis. We hypothesized that the osteogenic tendency of these patients might enhance the graft-host union and new bone formation in the femoral head, although the presence of heterotopic ossification might influence adversely the clinical result. Of patients with femoral head osteonecrosis, 32% developed heterotopic ossification after treatment with free vascularized fibular graft. Heterotopic bone formation did not influence the efficacy of the procedure to preserve the hip joint. The radiographic and clinical results and the rate of subsequent total hip arthroplasty were not affected by the heterotopic bone, but local trochanteric tenderness was associated with large heterotopic lesions.     

Free vascularized fibula graft to treat chondroblastoma of the hip

Chondroblastomas are rare tumors that present in the epiphysis of the long bones. Bone grafting following aggressive surgical curettage has yielded the best results. When present in the femoral head, they pose a higher risk of recurrence due to the difficulty of achieving an adequate resection without destroying the structural integrity of the weight-bearing surface. This article describes a case of surgical treatment of a chondroblastoma of the femoral head with the use of a free vascularized fibula graft. A 26-year-old woman had several months of increasing left hip pain and decreased range of motion. Imaging studies confirmed a large bubbly lesion with sclerotic borders in the left femoral head consistent with chondroblastoma. After performing an aggressive and complete excisional biopsy, a large cavitary defect remained in the femoral head. Reconstruction of the defect and structural support was achieved using a free vascularized fibula. Nine years postoperatively, the patient had full hip motion, no pain, and no radiographic evidence of collapse. A free vascularized fibula graft is an excellent option for the reconstruction of a large femoral head defect after chondroblastoma resection.
