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.
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.
ObjectiveTo evaluate the safety and effectiveness of one-stage posterior surgery via unilateral musculussacrospinalis iliac flap approach in treatment of lumbosacral tuberculosis.MethodsBetween August 2011 and October 2014, 13 patients with lumbosacral tuberculosis were treated by one-stage posterior reserved posterior ligament complex, lesion debridement, bone graft fusion, and internal fixation via unilateral musculussacrospinalis iliac flap approach. There were 8 males and 5 females, aged from 22 to 57 years, with an average age of 35 years. The disease duration ranged from 2 to 19 months, with an average of 6.7 months. According to the American Spinal Injury Association (ASIA) classification criteria, the patients were graded as grade B in 2 cases, grade C in 4 cases, grade D in 5 cases, and grade E in 2 cases before operation. The preoperative Oswestry disability index (ODI) was 36.4±5.7; the preoperative lumbosacral angle was (20.7±0.7)°; the preoperative erythrocyte sedimentation rate (ESR) was (63.4±8.4) mm/1 h; and the preoperative C-reactive protein (CRP) was (38.8±5.2) mmol/L. The operation time and intraoperative blood loss were recorded. The ODI, ASIA grade, lumbosacral angle, and ESR were recorded at last follow-up. Bridwell criterion was used to judge the interbody fusion.ResultsThe operation time was 150-240 minutes (mean, 190 minutes), and the intraoperative blood loss was 420-850 mL (mean, 610 mL). No major blood vessel, dural sac, nerve root, and lumbosacral plexus injuries occurred during the operation. Delayed wound healing occurred in 3 cases, and primary wound healing achieved in the other patients. No wound infection or sinus formation was found. All 13 patients were followed up 1.5-6.1 years (mean, 2.8 years). During the follow-up period, there was no tubercular symptom, cerebrospinal fluid leakage, loosening and rupture of internal fixator; and no complications such as retrograde ejaculation and erectile dysfunction occurred in 8 male patients. Solid spinal fusion obtained in all patients with the mean fusion time of 6.4 months (range, 4.2-9.9 months); and all iliac osteotomies healed. At last follow-up, the ODI was 7.2±3.5, the lumbosacral angle was (31.2±0.5)°, and ESR was (9.8±2.5) mm/1 h, all of which improved significantly when compared with pre-operative ones (P<0.05). The patients were classified as grade D in 2 cases and grade E in 11 cases, which improved significantly when compared with preoperative ones (Z=–3.168, P=0.002).ConclusionOne-stage posterior surgery via unilateral musculussacrospinalis iliac flap approach in treatment of lumbosacral tuberculosis is effective and safe.
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.
