摘要
As important indicators in clinical orthopaedics, proximal femoral geometry (PFG) is affected by many factors. However, current information is still limited regarding the effects of age on PFG in Chinese population. Therefore, the present study aimed to explore the influences of age on PFG on Chinese Han healthy adults. PFG of femoral version (FV), neck-shaft angle (NSA), acetabular anteversion (AA), femoral offset (FO), femoral head diameter (FHD), femoral neck diameter (FND) and femoral neck length (FNL) were measured in 466 Chinese Han healthy adults (353 males and 113 females). Included adults were divided into seven groups based on age of 18 to 29 years, 30 to 39 years, 40 to 49 years, 50 to 59 years, 60 to 69 years, 70 to 79 years and over 80 years, respectively. Analyses for all and stratified analyses by gender and laterality were performed. We found significant differences of NSA (P = 0.000) and AA (P = 0.000) among the age groups, which indicated that NSA may decrease while AA may increase with age. However, no significant differences were found regarding FV (P = 0.616), FO (P = 0.631), FHD (P = 0.807), FND (P = 0.993) or FNL (P = 0.070). Outcomes of Pearson correlation analysis showed a negative relationship between NSA and age (P = 0.000) but a positive association between AA and age (P = 0.000). In the stratified analysis by gender, statistical differences were identified in males regarding NSA (P = 0.003), AA (P = 0.000) and FNL (P = 0.043). With respect to females, significant differences were found in FV (P = 0.014), AA (P = 0.024), FND (P = 0.041) and FNL (P = 0.038). Stratified analyses by body laterality revealed similar outcomes with those for all. Our outcomes suggest a negative association between NSA and age but a positive association between AA and age in the Chinese cohort we reviewed. Additionally, gender differences may exist regarding changes of PFG with age.
