Abstract:
[Objective]To investigate the clinical value of OCM approach of minimally invasive total hip arthroplasty(MIS-THA).[Method]From February 2005 to December 2006,18 cases of MIS-THA were performed with OCM approach technique.The mini-incision through the intermuscular interval provided a good exposure for total hip replacement,preserved muscle integrity and kept the posterior capsule intact.A two-stage osteotomy of femoral neck was conducted.Specialized acetabular and femoral instruments were applied to fix the prosthesis.[Result]The average length of skin incision was 9.2 cm,the blood loss and drainage were 230 ml and 90 ml,respectively.At 6 months after operation,the mean Harris scores of hip increased from 46.2 to 87.1 for all cases.One case of femoral fracture around prosthesis and one of excessive anteversion were observed.[Conclusion]OCM approach brought satisfactory clinical outcomes when applied in MIS-THA.This surgical technique shows an obvious learning curve,but requires specialized instruments.
