摘要
背景:切开复位钢板置入内固定治疗髋臼前柱骨折时,螺钉穿入关节面的情况时有发生,为预防该并发症,对前柱钢板技术髋臼区安全置钉的定量解剖学测量非常有必要。目的:为前柱钢板髋臼区安全置钉提供解剖学依据。方法:利用Mimics软件对40例男性、40例女性骨盆CT进行三维重建,使用软件的切割工具制作前柱髋臼系列断面。使用软件测量工具,对各断面上不同进钉点的安全进钉方向及长度进行测量。将数据输入SPSS13.0软件进行统计学分析。结果与结论:髋臼前后缘、前缘到髂耻隆起的距离,分别为男性(56.63±2.05)mm,(12.30±1.51)mm;女性(49.07±5.07)mm,(16.93±1.74)mm;髋臼后缘到髂耻隆起的距离为男性(45.46±3.44)mm,女性(33.72±6.85)mm。螺钉在矢状面与髂骨板的夹角为男性(72.17±0.93)°,女性(81.05±0.92)°。B、C和D各断面,斜冠状面上螺钉与髂骨板的最大夹角分别为男性(53.88±3.01)°,(43.22±1.86)°,(54.60±2.97)°;女性(49.54±1.81)°,(39.10±1.22)°,(47.91±2.23)°。提示利用三维模型测量前柱髋臼区解剖特点,对于前柱骨折钢板置入内固定过程中避免螺钉进入关节有重要的指导意义。
BACKGROUND：During open reduction and plate fixation for acetabular anterior column fracture, screw penetrating the articular surface often occurred. To prevent this complication, quantitative anatomical measurement is very important for safe pedicle screw in acetabular area using anterior column plate technology. OBJECTIVE：To provide anatomical basis for screwing placement safely in acetabular anterior column plate. METHODS：Mimics Software was used to perform three-dimensional reconstruction of the 40 cases of male pelvic and 40 cases of female pelvic CT scan data. The cutting tool was used to make serial cross-sections of the acetabular anterior column and the measuring tool was used to determine the safe length and direction of screw entry on al entry points of each cross-section. Al data were uploaded into SPSS 13.0 software for statistics process. RESULTS AND CONCLUSION： The distance from anterior acetabular margin to posterior acetabular margin and iliopubic eminence was as folows： in males： （56.63±2.05） mm, （12.30±1.51） mm, and in females： （49.07±5.07） mm, （16.93±1.74） mm, respectively. The distance from posterior acetabular margin to iliopubic eminence was as folows： in males： （45.46±3.44） mm, and in females： （33.72±6.85） mm. The safe entry angle of screws to iliac plate in the sagittal plane was （72.17±0.93）° in males, and （81.05±0.92）° in females. On each section of B, C and D, the maximum of the safe entry angle of screws to iliac plate in the oblique coronal plane was （53.88±3.01）°, （43.22±1.86）°, （54.60±2.97）° in males; and （49.54±1.81）°, （39.10±1.22）°, （47.91±2.23）° in females, respectively. Results indicated that three-dimensional model can be used to measure anatomic characteristics of acetabular anterior column plate and has important instruction significance for avoiding screwing into joint in acetabular anterior column plate technique.
