BACKGROUND:Pelvic and acetabular fractures in elderly are frequently observed in the clinic, and the incidence gradual y increased. Moreover, it is difficult to conduct reduction and fixation due to their physical status and osteoporosis to different degrees. Locking plate is ideal fixation material in surgical treatment of acetabular fractures in elderly due to the special functions and good molding of screw and locking plate. OBJECTIVE:To analyze the advantages and disadvantages of locking reconstruction plate used in the acetabular fracture for the aged patients and to improve the clinical effect of acetabular fractures in elderly. METHODS:From January 2010 to February 2013, 21 aged patients with acetabular fracture were treated by open reduction and internal fixation with locking reconstruction plates made of titanium and 00Cr 18 Ni 14 Mo 3 stainless steel in the Department of Orthopedics Affiliated Hospital of Jining Medical University. RESULTS AND CONCLUSION:Of 21 patients, 20 cases were fol owed up for 12-18 months (mean 14 months), but one dropped out. Al the fractures were healed within 4-6 months and no failure cases. According to Matta evaluation criteria, the satisfactory rate was 90%. According to the D’Aubigne scoring system, the excellent and good rate was 95%. These data indicated that locking reconstruction titanium plate is reliable, has low failure rate and satisfactory clinical effects for acetabular fracture in aged patients, and is ideal fixation material in treatment of acetabular fractures in elderly.%背景：老年骨盆和髋臼骨折在临床上时常碰到，且发病率逐年上升，而且老年人群身体状况的特殊性及不同程度的骨质疏松，复位及固定困难。重建锁定接骨板由于螺钉和接骨板锁定的特殊性能及良好的塑型，是老年髋臼骨折手术治疗中的理想内固定材料。 目的：分析重建锁定钛接骨板在老年人髋臼骨折手术中的优缺点，提高老年性髋臼骨折的治疗效果。 方法：收集2010年1月至2013年2月于济宁医学院附属医院创伤骨科进行治疗的老年性髋臼骨折21例，均采用纯钛及00Cr 18 Ni 14 Mo 3不锈钢制成的重建锁定接骨板切开复位内固定治疗。 结果与结论：21例患者中1例未随访，其余20例均获得随访，随访时间12-18个月，平均14个月，所有骨折均在4-6个月愈合，无内固定失效病例发生，患者Matta评价标准复位满意率为90%；D’Aubigne功能评分优良率95%。提示重建锁定钛接骨板在老年髋臼骨折治疗中具有固定确实可靠、失败率低、临床效果满意等优点，是比较理想的治疗老年髋臼骨折的内固定材料。
