Abstract:
[Objective]To study the effect of femoral offset and hip joint center on joint function after total hip replacement,radiographic measurements were taken postoperation.[Method]A series of 92 hip joints(87 patients)were followed up.The average follow up priod was 25 monthes.The femoral offset and the position of the prothesis head center were measured in the orthophoric hip joint X-ray photograph and were compared with anatomic Fo and HJC.H arris evaluation system was used to evaluate joint function in four groups.The results were statistically analyzed,with Fisher' exact probability and P value less than 0.05 indicating significant difference.[Result]The coincidence rate of group A(both FO and HJC,27 hips)was 29.35%,group B(only Fo,23 hips)25.00%,group C(only HJC,31 hips)33.70%,group D(neither FO nor HJC,11 hips)11.96%.93.0% patients got the Harris score more than 80 for group A,73.19%(group B),74.19%(group C),27.27%(group D).The difference of Harris evaluation between A and B,A and C,A and D was significant statistically.[Conclusion]Based on the results of the study,the recovery of femoral offset and hip joint center should be considered to contribute to the healing effect after total hip replacement directly.
