ObjectiveTo explore the way and therapeutic effect of one stage total hip replacement (THR) in treating ischemic necrosis of femoral head combined with intertrochanteric fracture.MethodsFrom July 1997 to September 2005, one stage THR was performed in 18 cases (11 left and 7 right) of ischemic necrosis of femoral head combined with fresh intertrochanteric fracture, including 13 males and 5 females, with an age range of 32-60 years. There were 11 primary cases, 2 cases of ankylosing spondylitis, 2 cases of rheumatic arthritis, 2 cases of congenital acetabular dysplasia and 1 case of femoral neck fracture fixed using cannulated cancellous screws postoperatively in all cases of ischemic necrosis of femoral head. They suffered from ischemic necrosis of femoral head for 8 years (4-23 years). According to Evan's intertrochanteric fracture classification, there were 4 cases of type II, 6 cases of type III, 5 cases of type IV and 3 cases of type V. According to the Ficat ischemic necrosis of femoral head classification, there were 5 cases of type III, and 13 cases of type IV. The disease course was 2-12 hours. The average value of Harris evaluation was 35.2 preoperatively. The prosthesis of biology was used.ResultsAll wounds healed by first intention. One case suffered deep venous thrombosis 3 days postoperatively and recovered completely after treatment. No infection of urinary system and lung as well as no bedsore occurred postoperatively. The X-ray films showed that the fracture ends healed and that prosthesis had good form attitude and position after 4 months of operation. All cases were followed up for 2 years. They could walk and take care of themselves after 6 months. The average value of Harris evaluation was 94.7 points postoperatively (P < 0.05). The results were excellent in 15 cases, good in 2 cases, fair in 1 case according to Harris evaluation standard of THR; the excellent and good rate was 94.4%.ConclusionOne stage THR for treating ischemic necrosis of femoral head combined with intertrochanteric fracture can avoid secondary operation. It could resume the ideal function of the hip joint.
