Estudio cadavérico de anteversión de cuello femoral en Población de Indonesia / Cadaveric Study Of Femoral Neck Anteversion In Indonesian Population

Objective: The normal morphology of femoral anteversion is an essential factor which determines the clinical results of hip replacement to achieve the normal activity and the length of the replaced joint. No previous study has been documented regarding normal value of femoral anteversion in Indonesian population and how they are different with Western, India and African population. This study aimed on measurement of normal femoral anteversion values of Indonesian population and compare it with existing data of Western, African and India values. Method: This cross-sectional study by measuring the femoral neck anteversion angle in 120 samples of Indonesians's cadaveric femur. Comparisons were made between Western, African and India. Result: The result showed that the average values of femoral neck anteversion angle in men were 11.60 ± 4.83 and 12.96 ± 5.1 in the right and left parts respectively, while in women, the results were 14.83+-5.14 and 13.37+-5.66 in right and left parts. The p value of ≤ 0.05 was considered to be significant. Conclusion: The mean femoral anteversion values of Indonesian population is 13.22. It is significantly different in comparison with Western, African, and Indian population.

Measurement of the femoral neck torsion angle and anteversion angle by laser projection method / 解剖学报

Objective To investigate the feasibility of measuring femoral neck torsion angle and anteversion angle by laser projection method .Methods The femoral neck torsion angle and anteversion were observed and described .An angle measuring device was designed and produced .With the device , the femoral torsion angle and anteversion angle were measured by laser projection method two times .Statistical analysis was performed on the measured value , and sides difference .Results The differences between femoral neck torsion angle and anteversion angle were observed .There was no significant difference ( P >0.05, power =100%) between the two measurements by laser projection method . Measurements of the femoral anteversion were 13.58 °±6.55 °on the left side , and 12.15 °±5.83 °on the right side . Measurements of the femoral neck torsion angle were 18.50 °±7.38 °on the left and 19.08 °±8.59 °on the right .There was no significant difference between left and right side ( P >0.05 ) .Conclusion The laser projection method is the effective method in measuring femoral neck torsion angle and anteversion angle , and has excellent repeatability .
