成人股骨上端部分参数测定

背景：在髋部骨折治疗中，内植物的设计和匹配对实现力学的传导及获得长期稳定具有熏要意义。然而由于人种的遗传，生活、工作环境等的影响，从而造成人种股骨参数各异。目的：测定重庆地区成年人股骨上端部分参数。方法：利用游标卡尺实体测量160例重庆地区股骨标本（左右各80例）的股骨头直径、股骨头长径、头颈轴长等5项相关参数，用浩辰CAD软件在影像资料上测量重庆地区成人股骨（男女各80例）上端内、外侧弧度及头颈轴线与股骨外侧皮质夹角。结果与结论：实体测量重庆地区股骨标本得出人股骨头直径为（45．26±3．17）mm；股骨头长径为（39．02±2．58）mm；头颈轴长为（93．23±5．43）mm；股骨颈最小上下颈为（31．28±2．18）mm；股骨颈最小前后径为（26．23±2．10）mm；测量成人股骨影像学资料得出的男性股骨上端内侧弧度为（0．267±0．024）TT；男性股骨上端外侧弧度为（0．219±0．019）TT；男性头颈轴线与股骨外侧皮质夹角为（130．92±2．31）°；女性股骨上端内侧弧度为（0．278±0．019）TT；女性股骨E端外侧弧度为（0．219±0．019）TT；女性头颈轴线与股骨外侧皮质夹角为（130．68±2．02）°。实体测量的股骨头直径、股骨头长径、股骨头颈轴长、股骨颈最小前后径和股骨颈最小上下径呈正相关，相关系数为0．246—0．588。软件测量的影像学数据中股骨上端内、外侧弧度无相关性（P〉0．05）；头颈轴线与股骨外侧皮质夹角和股骨上端内侧弧度呈负相关（r日：一0．446，ra=一0．509，P〈0．05），而与股骨，卜端外侧弧度呈正相关（r=0．259，ra=0．311，P〈0．05）。测得的重庆地区成人股骨上端的部分参数为设计及改良出符合当地髋部骨折的内固定物提供参考依据。

Measurement of partial adult proximal femur parameters

BACKGROUND： In the treatment of hip fracture, the design and matching of the internal implants has great significance in achieving mechanical conduction and obtaining long-term stability. However, the impacts of racial heredity and life and work environment will result in differences in race femoral parameters. OBJECTIVE： To determine the partial proximal femoral parameters in the adults of Chongqing. METHODS： Vernier caliper was used to measure five related parameters of femoral head （femoral head diameter, femoral head length, head and neck axis length） of 160 femoral specimens （80 cases of left and right respectively） in Chongqing. Chen CAD software was used to measure the inside and outside radian, angle between head neck axis and lateral femoral cortex on the images of the femur in the patients （80 cases of male and female respectively） of Chongqing. RESULTS AND CONCLUSION： The entity measurement showed the femoral head diameter was （45.26±3.17） mm; femoral head length was （39.02±2.58） mm; head and neck axis length was （93.23±5.43） mm; minimum upper and lower femoral neck diameter was （31.28±2.18） mm; minimum anterior and posterior femoral neck diameter was （26.23±2.10） mm; measurement of the adult femoral images showed the male inside upper femoral radian was （0.267±0.024） Tr; male outside upper femoral radian was （0.219±0.019） °; angle between male head neck axis and lateral femoral cortex was （130.92±2.31）°; female inside upper femoral radian was （0.278±0.019） Tr; female outside upper femoral radian was （0.219±0.019） TT; angle between female head neck axis and lateral femoral cortex was （130.68±2.02）°. The femoral head diameter was positively correlated with femoral head length, head and neck axis length, minimum anterior and posterior femoral neck diameter and minimum upper and lower femoral neck diameter, and the correlation coefficient was 0.246-0.588. There was no significant correlation between the inside and outside upper femoral radian in the software measured imaging data （P 〉 0.05）; the angle between female head neck axis and lateral femoral cortex was negatively correlated with the inside upper femoral radian （r=-0.446, rfemae=-0.509, P 〈 0.05）, while positively correlated with the outside upper femoral radian （rmae =0.259, rfeme =0.311, P 〈 0.05）. The measurement of partial adult proximal femur parameters can provide reference for the design and production of internal fixation implants that meet the requirement of fixator for local hip fracture.
