To measure the anatomic data of the proximal femur and to design an internal fixation instrument aiming at subtrochanteric fracture.
We measured the anatomic data of 56 pairs of the matching proximal femur specimens: the diameter of femoral head (HD), the axis length of femoral head (HAL), 135 degree femoral head-neck axis length (HNAL), 135 degree femoral head-neck axis upper length (HNAUL), 135 degree femoral head-neck axis underside length (HNADL), the anterior-posterior axis diameter of femoral neck (NAPD), the upper-underside diameter of femoral neck (NUUD), femoral neck-shaft angle (NFA), femoral shaft lateral cortex-greater trochanter angle (SLGA), the medial-lateral diameter of lesser trochanter level's femoral shaft (LSMLD), the anterior-posterior diameter of lesser trochanter level's femoral shaft (LSAPD), the medial-lateral diameter of 5 cm below lesser trochanter femoral shaft (5 cm MLD), and the anterior-posterior diameter of 5 cm below lesser trochanter femoral shaft (5 cm APD). Part of the data was analyzed and compared.
HD was (46.69+/-3.73) mm, HAL was (39.22+/-4.17) mm, HNAL was (95.45+/-8.16) mm, HNAUL was (84.02+/-7.11) mm, HNADL was (99.95+/-9.34) mm, NAPD was (26.27+/-3.15) mm, NUUD was (32.24+/-3.31) mm, NFA was 126.21 degree+/-7.13 degree, SLGA was 16.38 degree+/-4.04 degree, LSMLD was (31.05+/-3.57) mm, LSAPD was (27.63+/-2.96) mm, 5 cm MLD was (26.36+/-3.22) mm, and 5 cm APD was (25.59+/-2.75) mm. NFA was positively correlated with SLGA (r=0.396, P=0.003).
It is necessary to design internal fixator to fit the anatomical feature of Chinese femur for the treatment of subtrochanteric fracture, and we should thoroughly consider the angle of the SLGA.
测量股骨近端的解剖数据，并针对转子下骨折设计一种内固定器械。
我们测量了56对匹配的股骨近端标本的解剖数据：股骨头直径（HD）、股骨头轴长（HAL）、135度股骨头颈轴长（HNAL）、135度股骨头颈轴上长度（HNAUL）、135度股骨头颈轴下长度（HNADL）、股骨颈前后径（NAPD）、股骨颈上下径（NUUD）、股骨颈干角（NFA）、股骨干外侧皮质-大转子角（SLGA）、小转子水平股骨干的内外径（LSMLD）、小转子水平股骨干的前后径（LSAPD）、小转子以下5 cm股骨干的内外径（5 cm MLD）以及小转子以下5 cm股骨干的前后径（5 cm APD）。对部分数据进行了分析和比较。
HD为（46.69±3.73）mm，HAL为（39.22±4.17）mm，HNAL为（95.45±8.16）mm，HNAUL为（84.02±7.11）mm，HNADL为（99.95±9.34）mm，NAPD为（26.27±3.15）mm，NUUD为（32.24±3.31）mm，NFA为126.21度±7.13度，SLGA为16.38度±4.04度，LSMLD为（31.05±3.57）mm，LSAPD为（27.63±2.96）mm，5 cm MLD为（26.36±3.22）mm，5 cm APD为（25.59±2.75）mm。NFA与SLGA呈正相关（r = 0.396，P = 0.003）。
治疗转子下骨折有必要设计适合中国股骨解剖特征的内固定器，且应充分考虑SLGA的角度。
