摘要:

背景:已有多项研究表明骨髓干细胞的数量减少和活力降低与股骨头坏死的发病机制密切相关,因此移植足够数量的骨髓干细胞更有利于解决坏死区的修复重建问题。
目的:分析病灶清除植骨联合骨髓单个核细胞治疗早期股骨头坏死的临床疗效。
方法:2011年3月至2012年7月收治25例33髋股骨头坏死患者,男15例,女10例;年龄18-55岁,平均34.6岁;病程8-20个月,平均14个月。病因:激素性5例7髋,酒精性4例5髋,特发性16例21髋。ARCO分期:ⅡA期8髋,Ⅱ B期15髋,Ⅱ C期9髋,Ⅲ A 期1髋,治疗前Harris评分为(55.2±6.5)分,目测类比评分为(6.81±1.19)分,MRI测量股骨头坏死体积为(13.38±5.1) cm3。经过病灶清除植骨及自体骨髓单个核细胞移植,随访观察Harris评分、目测类比评分和MRI测量股骨头坏死体积。
结果与结论:治疗后患者切口均Ⅰ期愈合,所有患者均获随访,随访时间12-18个月,平均15个月。治疗后3,6个月,1年Harris评分明显高于治疗前,目测类比评分和坏死体积值明显低于治疗前,差异有显著性意义(P < 0.05)。治疗后1年时Harris评分为(85.6±7.8)分,目测类比评分为(2.38±0.73)分,坏死体积为(7.23±3.3) cm3。髋关节功能评估:优15髋,良11髋,可4髋,差3髋(最终进行全髋关节置换)。结果表明病灶清除植骨联合自体骨髓单个核细胞移植治疗早期股骨头坏死近期疗效肯定,远期效果仍有待进一步观察。

Abstract:

BACKGROUND: Several studies have indicated that reduced number and viability of bone marrow stem cells is closely related to the pathogenesis of osteonecrosis. Therefore, a sufficient number of transplanted bone marrow stem cells are more conducive to the reconstruction of necrotic area.
OBJECTIVE: To analyze the clinical effect of debridement, bone grafting combined with autologous bone marrow mononuclear cells transplantation for the treatment of early avascular necrosis of the femoral head.  
METHODS: From March 2011 to June 2012, 25 patients (33 hips) were treated, including 15 males and 10 females, aged 18-55 years old (34.6 on average). The average disease course was 14 months (range, 8-20 months). Based on the etiology, there were 5 steroid-induced cases (7 hips), 4 alcohol-induced cases (5 hips), 16 idiopathic cases (21 hips). According to the system of the Association Research Circulation Osseous (ARCO), 8 hips were classified as stage IIA, 15 hips as stage IIB, 9 as stage IIC, 1 as stage IIIA. Before treatment, the Harris score was (55.2±6.5) points, visual analog scale score was (6.81±1.19) points, and the volume of the necrotic femoral head with MRI was (13.38±5.1) cm3. After treatment with debridement, bone grafting combined with autologous bone marrow mesenchymal stem cells transplantation, the Harris score, visual analog scale score and the volume of the necrotic femoral head with MRI were measured.
RESULTS AND CONCLUSION: All incisions healed by first intention. All the 25 patients (33 hips) were followed up for 12-18 months (15 on average). The Harris score was significantly higher, but the visual analog scale score and the volume of the necrotic femoral head were significantly lower at 3, 6, 12 months after operation compared 
with baseline data (P < 0.05). At postoperative 1 year, the Harris score was (85.6±7.8) points, the visual analog score was (2.38±0.73) points, and the volume of the femoral head necrosis was (7.23±3.3) cm3. There were 15 hips of excellent, 11 of good, 4 of fair and 3 of poor. Three poor hips were subjected to total hip arthroplasty at last. These findings indicate that the debridement, bone grafting combined with transplantation of autologous bone marrow mononuclear cells is an effective method to treat early early osteonecrosis of the femoral head, but the long-term effect needs to be observed further.
