@@@@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 wil 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) π; male outside upper femoral radian was (0.219±0.019) π; 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) π; female outside upper femoral radian was (0.219±0.019) π; 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 (rmale=-0.446, rfemale=-0.509, P < 0.05), while positively correlated with the outside upper femoral radian (rmale =0.259, rfemale =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.
