摘要:

背景:髋臼骨折属于关节内骨折,髋臼具有位置较深、外形不规则及毗邻重要血管神经等解剖学特点。髋臼骨折的治疗目的就是要精确恢复髋臼关节面的解剖对位,最大程度的保存髋关节功能。数字化技术对髋臼骨折的内固定治疗具有指导意义。
目的:探讨数字化技术辅助下内固定修复髋臼骨折的临床效果。
方法:2009年3月至2011年9月在解放军广州军区广州总医院创伤骨科收治50例髋臼骨折患者,随机分为2组。试验组25例应用数字化技术进行术前计划,并根据术前计划进行切开复位内固定;对照组25例未采用数字化技术进行切开复位内固定。比较两组患者在术中出血量、手术时间、住院时间及内固定后髋关节功能评分方面的差异。
结果与结论:试验组23例患者获得随访,随访时间13-24个月;对照组22例患者获得随访,随访时间12-26个月。试验组患者手术持续时间、术中出血量均显著小于对照组,差异均有显著性意义(P < 0.05)。内固定后试验组患者住院时间及骨折愈合时间均显著小于对照组,差异有显著性意义(P < 0.05)。内固定后试验组患者髋关节功能评分优良率显著高于对照组,差异有显著性意义(P < 0.05)。提示术前利用数字化技术进行髋臼骨折模型三维重建,模拟骨折复位,制定个体化方案,依据个体化方案进行切开复位内固定,内固定效果令人满意。

Abstract:

BACKGROUND: Acetabulum fracture is an intra-articular fracture. The acetabulum has a deep position, irregular shape and is adjacent to many important blood vessels and nerves. The purpose of treatment is to recover the anatomical contraposition of acetabulum joint surface accurately and to maximize the function of the hip retained. The digital technology has a guiding significance to the treatment of the acetabulum fracture.
OBJECTIVE: To investigate clinical therapeutic effect of internal fixation with the assistance of digital technology on acetabulum fracture.
METHODS: 50 patients with acetabulum fracture were recruited from Department of Orthopedic Trauma, Guangzhou General Hospital of Guangzhou Military Command of Chinese PLA between March 2009 and September 2011. The involved patients were divided into control group and study group randomly. 25 cases of  study group received preoperative plans through the digital technology and treated with open reduction and internal fixation according to the plans. 25 cases of control group were treated with operations only. The amount of bleeding during the operations, the duration of the operations, the duration of hospitalizations and the function evaluation after the operations were compared between the two groups.
RESULTS AND CONCLUSION: 23 cases had been followed up from 13 to 24 months in the study group and 24 cases had been followed up from 12 to 26 months in the control group. The amount of bleeding during the operations and the duration of the operations in the study group were significantly lower than that in the control group (P < 0.05). The duration of hospitalizations and the healing time of the fracture after the operations were significantly shorter in the study group than in the control group (P < 0.05). The hip function scores after the operations in the study group were significantly higher than that in the control group (P < 0.05). Using the digital technology we reconstruct the three-dimensional models of acetabulum fracture before surgeries can help imitating the fracture reductions and formulating the individualized operation plans. It has satisfactory effect to treat the patients with open reduction and internal fixation surgeries according to the plans.
