文题释义:
髓芯减压并植骨:单纯的髓芯减压对早期、受累范围较小的股骨头坏死具有一定疗效,但在股骨减压、清除坏死骨组织后,缺乏对股骨头负重区软骨下骨的力学支撑,尤其当减压面积较大时,会增加术后骨折及关节面进一步塌陷的风险,所以髓芯减压后在通道内打压植骨可增加股骨头的强度,改变负重的载荷,降低股骨头塌陷的可能性。
股骨头坏死:股骨头坏死是一个病理演变过程,初始发生在股骨头的负重区,在应力作用下坏死骨骨小梁结构发生损伤即显微骨折及随后针对损伤骨组织的修复过程,造成骨坏死的原因不消除,修复不完善,损伤-修复的过程继续,导致股骨头结构改变、股骨头塌陷、变形,关节炎症,功能障碍。
非细胞型组织工程骨:由自体红骨髓与骨诱导活性材料制成,不需要体外培养的过程,因此称为“非细胞型组织工程化骨”,该方法对患者创伤小,操作相对简单,临床易推广,不仅可改善股骨头血运,骨诱导活性材料诱导骨髓基质干细胞通过软骨骨化形成新骨,促进骨修复,而且早期填塞骨缺损,起到机械支撑的作用,对股骨头塌陷起到预防作用。
 
 
背景:临床研究中发现对于FicatⅡ期股骨头坏死尤其合并骨质疏松的病例,单纯髓芯减压伴或者不伴非细胞型组织工程骨植入治疗股骨头塌陷的发生率均较高。
目的:分析髓芯减压+非细胞型组织工程骨植入联合钛棒支撑治疗早期股骨头坏死的近期疗效。
方法:选择35例(40髋)早期股骨头坏死患者,观察组15例(20髋)行髓芯减压+非细胞型组织工程骨植入联合钛棒支撑治疗,骨坏死Ficat分期,Ⅰ期10髋,Ⅱ期10髋;对照组20例(20髋)行髓芯减压+非细胞型组织工程骨植入治疗,骨坏死Ficat分期,Ⅰ期11髋,Ⅱ期9髋。治疗后随访1年,评估目测类比评分、髋关节功能Harris评分及骨坏死进展情况。

结果与结论:①两组治疗后1年随访时的Harris评分及目测类比评分均优于治疗前(P < 0.001);观察组治疗后1年随访时Harris评分优于对照组(P < 0.05),目测类比评分与对照组比较无差异(P > 0.05);②对于骨坏死Ficat分期Ⅱ期患者,治疗后1年随访时,根据Harris评分,观察组治疗优良率高于对照组(80%,40%,P < 0.05);根据Ficat分期进展,观察组治疗有效率高于对照组(90%,80%,P < 0.05);③对于Ficat分期Ⅰ期患者,治疗后1年随访时均表现为病变修复较好,髋关节无退变、软骨下骨无塌陷;④结果表明,髓芯减压+非细胞型组织工程骨植入与髓芯减压+非细胞型组织工程骨植入联合钛棒支撑都是治疗早期股骨头坏死的有效方法,髓芯减压+非细胞型组织工程骨植入联合钛棒支撑治疗早期股骨头坏死的近期疗效更优。

Abstract:

BACKGROUND: For the Ficat II of femoral head necrosis especially with osteoporosis, core decompression with or without acellular tissue engineered bone can result in a higher incidence of femoral head collapse.

OBJECTIVE: To analyze the clinical effect of core decompression plus implantation of acellular tissue engineered bone with titanium rods in the treatment of early necrosis of the femoral head.
METHODS: Thirty-five hospitalized patients with early necrosis of the femoral head (40 hips) were enrolled in the study and assigned into a observation group (15 cases with 20 hips, including 10 hips of Ficat I, 10 hips of Ficat II) and a control group (20 cases with 20 hips, including 11 hips of Ficat I, 9 hips of Ficat II). Core decompression plus implantation of acellular tissue engineered bone with titanium rods were conducted in the observation group, while Bouche decompression with implantation of acellular tissue engineered bone was done in the control group. All the patients were followed up for 1 year. Visual analogue scale (VAS) score, Harris hip function score, and progression in necrosis of the femoral head were compared between two groups.
RESULTS AND CONCLUSION: VAS scores and Harris scores at 1-year follow-up in both groups showed better outcomes (P < 0.001). At the end of 1-year follow-up visit, the Harris score was significantly higher in the observation group than the control group (P < 0.05), while there was no difference in the mean VAS scores between the two groups (P > 0.05). For Ficat II patients, the excellent/good rate in the observation group was higher than that in the control group at the last follow-up (80% vs. 40%, P < 0.05). According to the Ficat staging, the effective rate in the observation group was higher than that in the control group (90% vs. 80%, P < 0.05). During the postoperative 1-year follow-up visit, Ficat I patients presented with better repair of lesions, no degeneration of the hip joint, and no subchondral bone collapse. Overall, it is an effective treatment for early necrosis of the femoral head by core decompression plus implantation of acellular tissue engineered bone with or without titanium rods; however, co-implantation with titanium robs can show better short-term outcomes.
