Minimally invasive total hip arthroplasty on hip ankylosis

Objective To discuss the technique and therapeutic effect of minimally invasive total hip arthroplasty on hip ankylosis.Methods From June 2006 to July 2009,13 patients(21 hips) with hip ankylosis,aged from 20 to 66(mean=46),received minimally invasive total hip arthroplasty.The causes of hip ankylosis included ankylosing spondylitis(10 hips of 5 patients),rheumatoid arthritis(6 hips of 4 patients),severe osteoarthritis secondary to aseptic necrosis of femoral head(3 hips of 2 patients),and ankylosing deformity after hip joint infection(2 hips of 2 patients).The abducent muscle of all patients had the contractile function.The implants consisted of metal-on-metal hip implants(13 artificial hip joints) and ceramic-on-ceramic hip implants(8 artificial hip joints).Results All the surgeries were successful,with surgical time of 80±12 min(minimum=60 min) and blood loss of 380±156 ml.Follow-ups of the patients were carried out for 12-48 months,and the X-ray results showed good artificial hip joint locations.There was no fracture during the surgeries.There was no implant dislocation,incision infection,deep venous thrombosis or other complications after the surgeries.The Harris scores before and after the surgeries were 45.6±6.2 and 86.6±7.3 points,respectively,exhibiting a statistically significant difference(P<0.05).Conclusion Minimally invasive total hip arthroplasty on hip ankylosis can effectively improve the function of hip joints,enhance the quality of life,reduce the wounds,and accelerate the recovery.
