  • TREATMENT OF AVASCULAR NECROSIS OF FEMORAL HEAD AFTER FEMORAL NECK FRACTURE WITH PEDICLED ILIAC BONE GRAFT

    Objective To explore the effectiveness of pedicled il iac bone graft transposition for treatment of avascular necrosis of femoral head (ANFH) after femoral neck fracture. Methods Between June 2002 and December 2006, 22 cases (22 hips, 16 left hips and 6 right hips) of ANFH after femoral neck fracture were treated with il iac bone graft pedicled with ascending branch of the lateral femoral circumflex vessels. There were 18 males and 4 females with an age range from 28 to 48 years (mean, 37.5 years). The time from injury to internal fixation was 2-31 days, and all fractures healed within 12 months after internal fixation. The ANFH was diagnosed at 15-40 months (mean, 22 months) after internal fixation. The ANFH duration was 3-11 months (mean, 8 months). According to Association Research Circulation Osseous (ARCO) staging system, 2 hips were classified as stage IIa, 3 hips as stage IIb, 3 hips as stage IIc, 3 hips as stage IIIa, 7 hips as stage IIIb, and 4 hips as stage IIIc. The preoperative Harris hip score (HHS) was 64.10 ± 5.95. Results All incisions healed by first intention and the patients had no compl ication of lung embol ism, sciatic nerve injury, lower l imb deep venous thrombosis, and numbness and pain of donor site. All patients were followed up 2.5 to 6.3 years (mean, 4.8 years). The fracture heal ing time was 8-12 months, and no femoral neck fracture recurred. The HHS was 90.20 ± 5.35 at last follow-up, showing significant difference when compared with the preoperative value (t= —18.447, P=0.000). The hi p function were excellent in 11 hi ps, good in 10 hips, fair in 1 hip, and the excellent and good rate was 95.5%. Four hips were radiographically progressed in ARCO staging, 18 hips remained stable with a stable rate of 81.8%. Conclusion Pedicled il iac bone graft transposition is an ideal option for treatment of ANFH after internal fixation of femoral neck fracture for the advantages of femoral head revascularization, sufficient cancellous bone supply, and relatively simple procedure.

  • 带旋髂深血管蒂髂骨及髂骨膜瓣移位治疗中青年股骨颈骨折

    目的 总结带旋髂深血管蒂髂骨及髂骨膜瓣移位治疗中青年股骨颈骨折的手术方法及临床疗效。 方法 2003 年4 月- 2007 年3 月,收治22 例中青年股骨颈骨折患者。男12 例,女10 例;年龄25 ~ 53 岁,平均42 岁。均为闭合性骨折。致伤原因:交通事故伤18 例,高处坠落伤4 例。受伤至手术时间5 h ~ 43 d。新鲜骨折20 例,陈旧性骨折2 例。骨折部位分型:头下型10 例,经颈型12 例。骨折Garden 分型:Ⅲ型6 例,Ⅳ型16 例。术前Harris 髋关节功能评分(22.80 ± 8.75)分。采用带旋髂深血管蒂髂骨及髂骨膜瓣移位加空心加压螺钉治疗。 结果 术后1 例供区伤口伴液化渗出,经换药治愈;其余切口均Ⅰ期愈合。术后患者均获随访,随访时间20 ~ 60 个月,平均42 个月。21 例股骨颈骨折愈合,愈合时间3 ~ 6 个月,平均3.5 个月;1 例骨折不愈合并股骨头缺血性坏死,于术后6 个月行人工全髋关节置换术。术后14 个月Harris 评分为(86.40 ± 7.95)分,与术前比较差异有统计学意义(P lt; 0.05)。 结论 带旋髂深血管蒂髂骨及髂骨膜瓣治疗中青年股骨颈骨折可改善骨折端血运,促进骨折愈合,减少股骨头坏死的发生。

  • Treatment Ischemic Necrosis of the Femoral Head with Vacularized Iliac Graft in Young Patients with Sickle-Call Disease

    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.

  • Clinical study of a new biodegradable magnesium internal fixation screw in treatment of osteonecrosis of the femoral head

    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.
