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.
Thirty-nine cases of fracturc of the femoral neck were treated by transplantation of iliac bone graft pedicled with the deep circumflex iliac vessel. The average period of the follow up was 89.4 months. The results showed that Harris Hip Functional Evaluation was 88.2±15.6. The rate of necrosis of the femoral head was 48.7 percent before being operated and 23.1 percent after being operated. The non-union rate of the fracture was 56.4 in contrast to 17.9 percent. The authors believed that the indications wer...
Objective To investigate the therapeutic effects of the vacularized iliac graft for ischemic necrosis of the femoral head in Niger young patients with sickle cell disease. Methods From November 1998 to Apirl 2001, 12 patients (5 males and 7 females, aging 11-22 years) with sickle cell disease suffered from ischemic necrosis of the femora! head in 14 hips. The lesion was on one hip in 10 patients and on bilateral hip in 2 patients. Necrosis was classified as Ficat Stage Ⅲ-Ⅳ in all patients. Twelve hips in 12...
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.
