摘　　要：目的:探讨球囊扩张后凸成形术(percutaneous kyphoplasty,PKP)治疗胸腰段骨质疏松性椎体骨折后并发再骨折与骨水泥注射量的关系。方法:自2006年1月至2008年12月对采用单侧经皮穿刺PKP术治疗的68例胸腰段骨质疏松性椎体骨折患者的临床资料进行回顾性分析,其中骨水泥注射量少于3ml(平均2.5ml)的患者30例(少量组),男11例,女19例;年龄60～91岁,平均(85.0±8.5)岁;骨水泥注射量大于4ml(平均4.5ml)的患者38例(多量组),男15例,女23例;年龄60～93岁,平均(86.0±9.2)岁。观察2组随访期内并发椎体再次骨折的因素并进行对比分析。结果:2组患者均获随访,随访时间3.4～5.1年,平均3.8年。少量组并发再次骨折13例(43.3%),其中强化椎体再骨折1例,上下邻节椎体骨折8例,远位节段椎体骨折4例;多量组并发再次骨折18例(47.3%),其中强化椎体再骨折2例,相邻椎体骨折10例,远位节段椎体骨折6例,2组比较差异无统计学意义(P>0.05)。结论:PKP治疗胸腰段骨质疏松性椎体骨折骨水泥注射量不是再次骨折的主要影响因素,并发骨折主要与骨质疏松的疾病自然进展有关,注射量以略超过球囊容积为宜。Objective：To explore relationship between volume of bone cement injection and concurrent of fracture after thoracolumbar osteoporotic vertebral fracture treated by percutaneous kyphoplasty （PKP）. Methods：From January 2006 to De- cember 2008,68 patients with thoracolumbar osteoporotic vertebral fracture treated by PKP were retrospectively analyzed. A- mong them,30 patients with less than 3 ml bone cement injection （mean 2.5 ml,low group）,including 11 males and 19 fe- males,with an average age of （85.0±8.5） years （ranging for 60 to 91 ） ; 38 cases with over 4 ml bone cement injection （mean 4.5 ml,large group）, including 15 males and 23 females,with an average age of （86.0±9.2） years （ranging for 60 to 93）. Factors of concurrent vertebral fractures were observed during follow-up. Results ：All patients were followed up from 3.4 to 5.1 years with an average of 3.8 years. Thirteen patients （43.3%） co-occurred fracture in low group,among which strengthened concurrent vertebral fracture occurred in 1 case, upper and lower section adjacent vertebral fracture in 8 cases, distal segment of vertebral fracture in 4 cases;while 18 patients （47.3%） co-occurred fracture in large group, among which strengthened con- current vertebral fracture occurred in 2 cases, upper and lower section adjacent vertebral fracture in 10 eases, distal segment of vertebral fracture in 6 eases. No significant difference between two groups （P〉0.05）. Conclusion：Bone cement injection is not main influence factors for treating concurrent of fracture after thoraeolumbar osteoporotie vertebral fracture by PKP. Concurrent fracture mainly relates with progress of osteoporosis, the volume of injection volume may appropriately over the volume of balloon.
