Treatment of osteonecrosis in the hip of pediatric patients by free vascularized fibular graft

The purpose of the current study was to review the demographics and etiologies of symptomatic femoral head osteonecrosis in the pediatric and adolescent population and to assess the results of treatment using free vascularized fibular grafting. A group of patients with femoral head osteonecrosis who were treated with free vascularized fibular grafting was reviewed. Patients who were studied were 18 years of age or younger at the time of surgery. Records were examined for demographic data, etiology of osteonecrosis, stage of the disease at time of surgery, and results of treatment including preoperative and postoperative Harris hip scores. Eighty-two pediatric and adolescent patients with osteonecrosis of the femoral head underwent 90 free vascularized fibular grafting procedures. Fifty patients (54 hips) who have been followed up at least 2 or more years (average, 4.3 years) constituted the study group. At the last followup, total hip arthroplasty was performed in seven hips (seven patients) and hip fusion was performed in one hip (one patient). The average Harris hip scores in patients who did not undergo total hip arthroplasty improved from a preoperative average of 55.3 points to 90.2 points at the latest followup. Treatment of patients with osteonecrosis with free vascularized fibular grafting resulted in a lower rate of conversion to total hip arthroplasty or fusion (16%) in pediatric and adolescent patients when compared with conversion to total hip arthroplasty in adults (25%). The quality of life as evidenced by the increased Harris hip scores was improved significantly in this group of pediatric and adolescent patients.     

Vascularized compared with nonvascularized fibular grafting for the treatment of osteonecrosis of the femoral head

BACKGROUND: We are not aware of any clinical studies in the literature comparing the results of vascularized and nonvascularized fibular grafting for the treatment of osteonecrosis of the femoral head. The purpose of this study was to compare the clinical results of free vascularized fibular grafting with those of nonvascularized fibular grafting. METHODS: Two hundred patients (220 hips) with osteonecrosis of the femoral head were treated with free vascularized fibular grafting at the University of Pittsburgh Medical Center, and ninety-nine patients (123 hips) were treated with nonvascularized fibular grafting at the Kyungpook National University Hospital in Korea. From these populations, two groups of fifty hips each, followed for a minimum of three years (average, five years), were matched by the stage, size, and etiology of the lesion and by the mean preoperative Harris hip score. A retrospective case-control study of these groups was then performed to compare the postoperative Harris hip scores as well as the prevalences of radiographic progression and collapse of the femoral head following free vascularized fibular grafting with those measures following nonvascularized fibular grafting. RESULTS: The mean Harris hip score improved for 70% of the hips treated with free vascularized fibular grafting: seventeen hips (34%) were rated excellent, fourteen (28%) were rated good, nine (18%) were rated fair, and ten (20%) were rated poor. The mean Harris hip score improved for 36% of the hips treated with nonvascularized fibular grafting: five hips (10%) were rated excellent; nine (18%), good; sixteen (32%), fair; and twenty (40%), poor. The rate of survival at seven years for the Stage-I and II hips (precollapse) was 86% after treatment with free vascularized fibular grafting compared with 30% after nonvascularized fibular grafting. CONCLUSIONS: The results of this study strongly suggest that vascularized fibular grafting is associated with better clinical and radiographic results.     

Modified surgical techniques of free vascularized fibular grafting for treatment of the osteonecrosis of femoral head: Results from a series of 407 cases

The goal for treatment of osteonecrosis of the femoral head (ONFH) is to relieve pain, preserve the contour of the femoral head, and delay the need for total hip arthroplasty. The free vascularized fibular grafting (FVFG) has been shown to support the subchondral architecture as well as restore local circulation for the necrotic femoral head in treatment of ONFH. This report aimed to present the clinical results of the use of a modified surgical technique of FVFG for treatment of ONFH. Four hundred and seven patients with 578 hips of ONFH were included. The patients' average age was 36.7 years old (ranging 19–55 years old). The disease was staged from II to V based on the Steinberg classification system. By the modified procedure, the vascularized fibular graft was harvested via a lateral incision with fibular osteotomy prior to the exposure of the vascular pedicle, and the removal of necrotic tissue and inset of graft were performed through an anterior approach. The operative time averaged 90 min for unilateral ONFH (ranging 75–110 min) and 190 min for simultaneous treatment of bilateral ONFH (ranging 160–230 min). The average length of follow‐up was 5.0 years (ranging 3–10 years). The complications included one infection in one case, temporary loss of sensation of the thigh in eleven cases, and restricted motion of the great toe in nine cases. The Harris hip score of patients improved from 65.0 to 86.9 on average. Radiographic evaluation showed no changes in 331 hips (57.3%), improvement in 195 hips (33.7%) and necrosis progression in 52 hips (9.0%). Twenty‐three hips (4.0%) in 20 patients had total hip arthroplasty during the period. These results show that the modified technique of the use of FVFG for treatment of ONFH yields similar postoperative results in comparison to the traditional method. © 2013 Wiley Periodicals, Inc.

Treatment of osteonecrosis of the femoral head by free vascularized fibular grafting: an analysis of surgical outcome and patient health status.

OBJECTIVE: To evaluate the limb-specific outcome and general health status of patients with osteonecrosis of the femoral head treated with vascularized fibular grafting. DESIGN: A retrospective review. SETTING: A single tertiary care centre. PATIENTS: Fifty-five consecutive patients with osteonecrosis of the femoral head who underwent fibular grafting (8 bilaterally). INTERVENTION: Vascularized fibular grafting. OUTCOME MEASURES: Limb-specific scores (Harris Hip Score, St. Michael's Hospital Hip Score), general health status (Nottingham Health Profile, SF-36 health status survey) and radiographic outcome measures (Steinberg stage). RESULTS: Patients were young (mean age 34 years, range from 18 to 52 years) and 80% had advanced osteonecrosis (Steinberg stages IV and V). Fifty-nine hips were followed up for an average of 50 months (range from 24 to 117 months) after vascularized fibular grafting. Sixteen hips (27%) were converted to total hip arthroplasty (THA). To date, 73% of hips treated with vascularized fibular grafting have required no further surgery. Preoperative and postoperative Harris Hip Scores were 57.3 and 83.6 respectively (p < 0.001). As measured by patient-oriented health status questionnaires (SF-36, Nottingham Health Profile) and compared with population controls, patients had normal mental health scores and only slight decreases in physical component scores. CONCLUSIONS: Free vascularized fibular grafting for osteonecrosis of the femoral head provides satisfactory pain relief, functional improvement and general health status and halts the progression of symptomatic disease.

Free vascularized fibular bone grafting in the management of femoral neck nonunion in patients younger than fifty years

PURPOSE: The incidence of nonunion and osteonecrosis after femoral neck fracture has been well documented. In older patients implant arthroplasty is well established as an acceptable treatment of these problems. However, in the younger population alternatives to implant arthroplasty are favored to preserve the femoral head. Surgical treatments for nonunion of the femoral neck include osteotomy, nonvascularized bone grafting, muscle-pedicle bone grafting, and vascularized bone grafting. The purpose of this study is to examine the results of free vascularized fibular grafting as a treatment of nonunion of the femoral neck in patients younger than fifty years. MATERIALS AND METHODS: Twenty-two consecutive patients underwent vascularized bone grafting for nonunion of the femoral neck after failed internal fixation between 1984 and 1998. The mean age of the patients was 28.7 years. There were thirteen male and nine female patients. The mean interval between internal fixation and free vascularized fibular grafting was 18.3 months. The average follow-up to date is 84.7 months (range 29 to 195 months). RESULTS: Twenty of twenty-two nonunions healed. Two patients required an additional procedure to facilitate union; one patient had iliac crest bone grafting at four months postoperatively and another underwent muscle-pedicle grafting at six months postoperatively. The average time to union for all patients was 9.9 months (range 3 to 23 months). Progression of osteonecrosis of the femoral head occurred in thirteen patients. However, successful long-term salvage of the femoral head was achieved in twenty of twenty-two patients, with an average Harris hip score of 78.9. Four patients required hardware removal or exchange for intraarticular migration with no long-term clinical sequelae. DISCUSSION: Rates of complications, such as nonunion and osteonecrosis, after femoral neck fractures in young patients have been reported to be as high as 86 percent. Treatments such as osteotomy, muscle-pedicle bone grafting, nonvascularized bone grafting, and vascularized bone grafting have reported variable results. Based on the results reported in this study, vascularized fibular bone grafting compares favorably with a high union rate (91 percent initially, 100 percent after secondary procedures) and successful long-term salvage of the femoral head in 91 percent of the patients. Free vascularized fibular bone grafting represents a promising solution for this difficult problem.     

Free vascularized fibular grafting for the treatment of postcollapse osteonecrosis of the femoral head

BACKGROUND: Osteonecrosis of the femoral head, a disease primarily affecting young adults, is often associated with collapse of the articular surface and subsequent arthrosis. Free vascularized fibular grafting has been reported to be successful for patients with early stages of osteonecrosis, but little is known about its efficacy after the femoral head has collapsed. METHODS: We retrospectively reviewed the results in a consecutive series of 188 patients (224 hips) who had undergone free vascularized fibular grafting, between 1989 and 1999, for the treatment of osteonecrosis of the hip that had led to collapse of the femoral head but not to arthrosis. The average duration of follow-up was 4.3 years (range, two to twelve years). We defined conversion to total hip arthroplasty as the failure end point, and we analyzed the contribution, to failure, of the size of the lesion, amount of preoperative collapse of the femoral head, etiology of the osteonecrosis, age of the patient, and bilaterality of the lesion. We used the Harris hip score to evaluate clinical status preoperatively and at the time of the most recent follow-up. RESULTS: The overall rate of survival was 67.4% for the hips followed for a minimum of two years and 64.5% for those followed for a minimum of five years. The mean preoperative Harris hip score was 54.5 points, and it increased to 81 points for the patients in whom the surgery succeeded; 63% of the patients in that group had a good or excellent result. There was a significant relationship between the outcome of the grafting procedure and the etiology of the osteonecrosis (p = 0.017). Patients in whom the osteonecrosis was idiopathic, associated with alcohol abuse, or posttraumatic fared worse than did those with other causes, including steroid use. Survival of the joint was not significantly related to the size of the femoral head lesion, but there was an increased relative risk of conversion to total hip arthroplasty with increasing lesion size and amount of collapse. Neither patient age nor bilaterality significantly affected outcome. CONCLUSIONS: Patients with postcollapse, predegenerative osteonecrosis of the femoral head appear to benefit from free vascularized fibular grafting, with good overall survival of the joint and significant improvement in the Harris hip score. The results of this femoral head-preserving procedure in patients with postcollapse osteonecrosis are superior to those of core decompression and nonoperative treatment, as reported in the literature. Patients with larger lesions and certain diagnoses, such as idiopathic and alcohol-related osteonecrosis, have worse outcomes.     

Treatment of osteonecrosis of the femoral head in lymphoma patients by free vascularised fibular grafting

The purpose of this study was to assess the outcomes of treatment of femoral head osteonecrosis using free vascularised fibular grafting in patients with Hodgkin’s disease and non-Hodgkin’s lymphoma. We retrospectively reviewed seven patients (14 hips) with lymphoma who underwent free vascularised fibular grafting for osteonecrosis of the femoral head, evaluating pre- and postoperative Harris hip scores, visual analog scale (VAS) pain scores, hip range of motion and radiographs. Patients were followed up for a minimum of 1.5 years (mean, 3.3 years). All these patients exhibited good recovery without severe life-threatening complications. The mean Harris hip score improved from 69 to 88, while average VAS pain score decreased from 54 to 18. At the latest follow-up, we found improvement or unchanged radiographs in all three hips with initial Steinberg stage II osteonecrosis and in nine of 11 hips with stage III or IV osteonecrosis. No hips failed treatment and underwent total hip arthroplasty. The clinical data demonstrated that free vascularised fibular grafting can slow or even halt progression of necrosis, and improve the function of the hip and quality of life in lymphoma patients.     

Pain relief following osteonecrosis of the femoral head treated by free vascularized fibular grafting

Background

Pain is the core and basic problem in the treatment of osteonecrosis of the femoral head (ONFH). However, it is unclear about the status of pain relief following ONFH treated by free vascularized fibular grafting (FVFG) and the level of pain relief contributed to clinical results. Therefore, we designed a consecutive and prospective study to investigate post-operative pain relief in the treatment of osteonecrosis of the femoral head by FVFG.

Methods

One hundred and fifty-one patients with unilateral osteonecrosis of the femoral head were enrolled consecutively for current prospective study from January to August of 2006. Patients were managed by modified technique of free vascularized fibular grafting. Pre-operative, post-operative Harris hip score (HHS) and Harris pain score (HPS) were recorded and compared statistically, meanwhile, correlation between disease severity and Harris hip score, Harris pain score were revealed.

Results

All patients had an average follow-up of 54.3?months. Post-operative Harris hip score could be improved from 73.7 to 83.5 averagely in stage-II patients, 64.6 to 78.9 in stage-III, and 53.6 to 72.4 in stage-IV. As for Harris pain score, it was elevated from 28.8 to 38.6 in stage-II patients, 25.5 to 36.6 in stage-III, and 21.8 to 34.2 in stage-IV. Taken together, HHS was improved from 67.7 to 80.3 (ΔHHS?=?12.6), and HPS was improved from 26.6 to 37.3 (ΔHPS?=?10.7) averagely.

Conclusions

Harris pain score could be employed to monitor prognosis of osteonecrosis of the femoral head treated by free vascularized fibular grafting. Improvement of HPS was the heaviest contributor to elevation of HHS, and both of them conceived of a close relationship with disease severity.
