ObjectiveTo investigate the surgical methods and effectiveness to use the iliac flap combined with anterolateral thigh flap for repair of the first metatarsal bone and large skin defect. MethodsBetween January 2013 and January 2016, iliac flap combined with anterolateral thigh flap was used to repair the first metatarsal bone and large skin defect in 9 patients. There were 5 males and 4 females, with a median age of 15 years (range, 10 to 60 years). The causes included traffic accident injury in 6 cases and crush injury of machine in 3 cases. The average time from injury to operation was 3 hours to 14 days (mean, 7 days). The size of skin soft tissue defect ranged from 10 cm×6 cm to 20 cm×10 cm. The size of first metatarsal bone defect ranged from 2 cm×1 cm to 5 cm×1 cm. The size of iliac flap was 3.0 cm×1.5 cm to 6.0 cm×1.5 cm, and the size of anterolateral thigh flap was 10 cm×6 cm to 20 cm×10 cm. The donor site was directly sutured or repaired by free skin graft. ResultsAfter operation, the composite flaps survived with primary healing of wound; the skin grafts at donor site survived and the incision healed by first intention. All patients were followed up 6 months to 2 years (mean, 1.6 years). X-ray examination showed that the bone healing time was 3.5-5.0 months (mean, 4 months). The flap had soft texture, good color and appearance. All patients could normally walk. According to the American Orthopaedic Foot and Ankle Society (AOFAS) standard, the foot function was excellent in 6 cases and good in 3 cases, and the excellent and good rate was 100% at last follow-up. ConclusionThe iliac flap combined with anterolateral thigh flap for repair of the first metatarsal bone and large skin defect is a practical way with good shape at one stage.
Objective To investigate the treatment method of ischemic necrosis of the femoral head by the transplantation of pedicled bone flap with deep iliac circumflex vessel in adult and to assess its curative effect. Methods From February 1996 to September 2003, 46 adult patients with ischemic necrosis of thefemoral head (58 coxas) were treated by transplantation of pedicled bone flap with deep iliac circumflex vessel. The locations were the left side in 34 coxas and the right side in 24 coxas（stage Ⅱ in 16 coxas, stage Ⅲ in 39 coxas and stage Ⅳ in 3 coxas）.Results Thirty-seven patients (40 coxas) were followed up 6 months to 10 years after operation. According to the assess of FanQishen,the result was excellent in 19 cases (21 coxas), good in 11 cases (12 coxas), fair in 5 cases (5 coxas) and poor in 2 cases (2 coxas). The postoperative excellent and good rate was 81%. Conclusion Operative treatment of ischemic necrosis of the femoral head in adult by transplantation of bone flap pedicled with deep iliac circumflex vessel has the characteristics of restoration of blood supply ofthe femoral head, decompression of marrow cavity, elimination of necrotic bone and support of the femoral head. It is an effective and advanced method for treatment of ischemic necrosis of the femoral head in adult.
Eight cases(10 hips) of avascular necrosis of femoral head in adults were treated with transplantation of sartorius musculo-skeletal graft through the greater trochanter since August 1990. The patients were followed up for 12 to 20 months,with disappearance of pain in 7 cases. The degree of hip motion was markedly increased. The good results rated 87.5 percent.
Objective To explore an improved method of treating avascular necrosis of the femoral head in young adults by grafting the sartorius muscle iliac bone flap. Methods From September 1994 to August 2003, 68 patients (57 males, 11 females; age, 16-58 years) underwent of the transplant the sartorius muscle oliac bone flap into the femoral head after decompression of the femoral head medullary core and removal of the dead bone and the fibrous tissue in the femoral head. The transplantation was performed on 31 patients left-unilaterally, on 37 patients rightunilaterally, and on 7 patients bilaterally. The pathological causeswere as follows: alcoholism in 52 patients, prolonged use of hormones in 6, traumain the hip in 6, and undetermined cause in 4. Their illness course ranged from 8 months to 4 years. According the Ficat staging, 10 patients belonged to Stage I (11 sides), 27 patients to Stage Ⅱ (31 sides), and31 patients to Stage Ⅲ (33 sides). Results The follow-up of the 68 patientsfor 2.5-11 years averaged 5.2 years revealed that based on the Harris evaluation for the hip function, 23 patients had an excellent result, 33 had a good result, 10 had a fair result, and 2 had a poor result. The excellent and good resultsaccounted for 82.3%. There was no recurrence after operation. Conclusion Thismethod has the following advantages: the lesion focus can be eradicated; enoughdecompression can be achieved, and the blood circulation for the femoral head can be rebuilt. The grafting of the sartorius muscle iliac bone flap can bring the osteogenesis components to the femoral head, promoting the reconstruction of the bones. This method is suitable and effective for the patients with avascular necrosis of the femoral head (Ficat Grades Ⅰ, Ⅱ and Ⅲ) in young adults.
Objective To investigate the safety and efficacy of a new biodegradable magnesium internal fixation screw for vascularized iliac bone flap grafting in treatment of osteonecrosis of the femoral head (ONFH). Methods Patients with ONFH admitted between July 2020 and February 2021 were selected as the research objects, and 20 patients (20 hips) met the selection criteria and were included in the study. The patients were divided into two groups (n=10) by central random method. The iliac bone flap was fixed with a new biodegradable magnesium internal fixation screw in the trial group, and the iliac bone flap was wedged directly in the control group. There was no significant difference (P>0.05) in gender, age, and side, type, Association Research Circulation Osseous (ARCO) stage, and disease duration of ONFH between the two groups. The operation time and intraoperative blood loss of the two groups were recorded. Laboratory tests were performed at each time point before and after operation, including white blood cell (WBC), electrolytes (K, Ca, P, Mg), blood urea nitrogen (BUN), serum creatinine (Scr), glomerular filtration rate (eGFR), lymphocyte ratio (CD4/CD8), immunoglobulin G (IgG), IgM, alanine transaminase (ALT), aspartate aminotransferase (AST). After operation, Harris score was used to evaluate the hip joint function. CT of the hip joint and X-ray films in anteroposterior and frog positions of the pelvis were used to review the iliac bone flap position, fusion, and screw biodegradation in the trial group. Results The vital signs of the two groups were stable, the incisions healed by first intention, and no adverse events occurred after operation. One patient in the control group refused to return to the hospital for follow-up at 3 months after operation, and 1 patient in the trial group refused to return to the hospital for follow-up at 1 year after operation. The rest of the patients completed the follow-up at 2 weeks, 3 months, 6 months, and 1 year after operation. Laboratory tests showed that there was no significant difference in WBC, electrolytes (K, Ca, P, Mg), BUN, Scr, eGFR, CD4/CD8, IgG, IgM, ALT, and AST between the two groups at each time point before and after operation (P>0.05). The operation time and intraoperative blood loss of the trial group were significantly less than those of the control group (P<0.05). The Harris scores of the two groups at 1 year significantly increased when compared with the values before operation and at 6 months after operation (P<0.05). There was no significant difference in Harris score between the two groups at each time point (P>0.05). Postoperative CT of hip joint and X-ray films of pelvis showed that the iliac bone flap reached osseous fusion with the fenestration of the head and neck junction of femoral head in the two groups at 1 year after operation, and no loosening or shedding of iliac bone flap was observed during follow-up. In the trial group, there were signs of dissolution and absorption of the new biodegradable magnesium internal fixation screws after operation, and the diameter of the screws gradually decreased (P<0.05); no screw breakage or detachment occurred during follow-up. Conclusion In the treatment of ONFH with vascularized iliac bone flap grafting, the new biodegradable magnesium internal fixation screws can fix the iliac bone flap firmly. Compared with the traditional iliac bone flap wedging directly, it has a shorter operation time, less intraoperative blood loss, and can obtain similar joint function.
