Dr. D. Chandrashekhar, Dr. K. Shashikantha
Abstract :
Background and aims:The knowledge of proximal femoral geometry is of outmost importance for designing the best femoral implants.Fractures of proximal femur involving the neck and trochanters are quite common.The increase in osteoarthritis cases in India is high.The final management in both the cases is total hip replacement with femoral implants.These implants are designed for western population whose constitutional and biomechanical factors vary from South Indian population.Race,climate,heredity and geographical areas have strong influence over the anthropometric parameters of bone. Hence this study is carried out to analyze the dimensions of proximal femora in South Indians and compare the results with the dimensions of available femoral implants and the available data from different regions including bilateral variations in unpaired femora.
Materials and methods: 50 Right and 50 Left dry human femora alongwith commonly used implants such as DHS PFN,Cancellous screws were studied.The parameters of proximal femora studied are NSA,Length of neck,Height of neck,width of neck and vertical diameter of the head of femora. Dimensions obtained were measured according to standard anthropometric guidelines and compared with the implants and theavailable data from different regions.
Result: Significant variations were seen in the obtained dimensions between proximal femoral parameters,implants and the available data.NSA has shown significant variations in unpaired femora with 127.70 in left femora and 125.70 in right femora.
Conclusion:Present study concludes that significant differences were found between the dimensions of SouthIndian proximal femora and the available data from different regions indicating ethnic variations.The bilateral variations of NSA are seen in unpaired femora.Therfore implants designed which are available in standard sizes mismatch SouthIndian femora.This study enlightens the Orthopaedic surgeons and Biomechanical engineers.
