| 摘 要： | 目的研究胫骨骨髓腔解剖特征，为临床应用提供形态学基础。方法25根成人胫骨标本摄取正侧位X线平片，并定义一系列测量参数进行测量。结果胫骨骨髓腔平均全长为(29.4±1.9)cm；髓腔狭段长度为(6.5±1.2)cm，上下开口指数分别为10.0±2.9和8.5±2.6；胫骨骨髓腔中心线向后的弧度平均为2.6°±1.4°。结论①髓内钉固定应限于胫骨狭点附近占胫骨骨髓腔全长1/5～2/5范围内的骨折；②交锁钉一期动态固定的骨折范围应限于胫骨狭段范围的骨折；③胫骨下段骨折适合逆向穿钉固定；④胫骨骨髓腔的弧度变化应成为髓内钉设计的考虑因素。

| Abstract: | Objective： To provide morphological basis for clinical application by investigating the morphological characteristics of tibial medullary cavity.Methods： A serial of parameters were defined and measured on the X-ray photos of 25 adult tibial specimens.Results： The total length of tibial medullary cavity was 29.4±1.95 cm, and the narrow part was 6.5±1.2 cm long.The proximal and distal opening K were 10.0±2.9 and 8.5±2.6 respectively.The arc of the middle line of medullary cavity was 2.6°±1.4°.Conclusion: 1.Only the fracture locating around the narrow point, about 1/5 ～2/5 of total tibial length is suitable for intramedullary nail fixation.2.The indication for dynamic interlocking nail fixation is also limited in this region.3.Perhaps retrograde nailing is a good method for distal tibial fracture.4.The arc of the tibial medullary cavity should be taken into account as a factor for intramedullary nail design. |
