Abstract:
A total of 17 hip joint lesion patients (24 hips) combined with ankylosing spondylitis and severe osteoporosis from March 1996 to March 2003.They.received autologous impaction bone graft and cementless total hip replacement.They were 20-52 years old,averagely 35 years.Harris score and X-ray method were used to evaluate clinical outcomes.A total of 17 patients (24 hips) were followed up for 36-120 months,averagely 87 months.Harris score increased from averagely 34 points (preoperation) to averagely 86.4 points (postoperation),resulting in an excellent and good rate of 87.5%.Radiograph showed that femoral prosthesis was closely fixed to proximal segment of the femur,without prosthetic infection or dislocation.One hip suffered from 5-mm prosthetic subsidence within 1 year following replacement,and no further subsidence following over 5-year follow up.The prosthesis showed good contact to sclerotin,without loose.It is suggested that bone mass has great effects on cementtess prosthetic replacement.Autologous impaction bone graft for bone remodeling provides a good method for total hip replacement in patients combined with ankylosing spondylitis and severe osteoporosis.The clinical outcome is satisfactory.
