Total hip repalcement for osteonecrosis of the femaoral head after failed internal fixation of femaoral neck fracture
摘要
Abstract
Objective To explore the therapeutic effect of total hip replacement (T HR) in treating osteonecrosis of the femoral head (ONFH) after failed internal fixation of femoral neck fracture .Methods From January 2003 to June 2012 ,32 cases (19 left hips and 13 right hips) of ONFH after failed internal fixation of femoral neck fracture were treated with THR .There were 18 males and 14 females with an age range from 35 to 62 years (mean ,50 .6 years) .The ONFH was diagnosed at 8-26 months (mean ,17 .1 months) after internal fixation ;the THR were conducted 15-48 months after first surgery (mean ,27 .2 months) .According to Fi‐cat classifi cation ,there were 8 cases at stage Ⅲ and 24 cases at stage IV .The Harris score was (40 .9 ± 9 .8) .The prosthesis of bi‐ology was used .Results All wounds healed by first intention .All cases were followed up for 6-48 months (mean ,28 .3 months) . The Harris score was (90 .8 ± 4 .4) at last follow‐up ,showing significant difference when compared with the preoperative value (P<0 .05) .The hip function were excellent in 25 hips ,good in 5 hips ,fair in 2 hip ,and the excellent and good rate was 93 .8% . There were 1 cases of periprosthetic femoral fracture(type C) ,2 cases of proximal femoral splitting fractures fractures .After corre‐sponding treatment ,fracture was healed in all cases .There were no complications (infection ,loosening dislocation or subsidence , etc) .Conclusion Total hip replacement is an effective method for the treatment of ONFH after failed internal fixation of femoral neck fracture .关键词
