ABSTRACT
Objective To compare the clinical results of femoral head replacement for femoral in- tertrochanteric fractures and femoral neck fractures in aged patients.Methods Forty cases of femoral in- tertrochanteric fractures and 45 cases of femoral neck fractures (aged over 80 years) underwent femoral head re- placement from August 1996 to April 2002 in our department.The clinical results of the two groups were retro- spectively compared and analyzed statistically.Their follow-up periods,ranging from 3 to 7 years,averaged 4.6 years in the intertrochanteric fracture group and 5.5 years in the neck fracture group.Results The differences in time of hospitalization,perioperative blood loss,postoperative drainage,ambulation trine,early compiications be- tween the two groups were of no statistical significance (P＞0.05).The differences in operation time and inequality in leg length after operation between the two groups were of statistical significance (P＜0.05).The operation time was longer and more limb-length inequality occurred in the intertrochanteric fracture group than in the neck fracture group.There was no significant difference in Harris score at the last follow-up between the two groups.The X-ray at the final follow-up showed that there was insignificant difference in postoperative hip joint space,hip pain,or stem loosening between the two groups (P＞0.05).The stem revision incidences were of no statistical significance be- tween the two groups (P＞0.05).The two groups reported no acetabular protrusion.Conclusion With standard cemented prostheses,femoral head replacements can achieve as similar functional outcomes for patients with in- tertrochanteric fractures as for those with femoral neck fractures.
