COMPARISON OF MINIMAL INCISION TOTAL HIP REPLACEMENT VERSUS STANDARD INCISION TOTAL HIP REPLACEMENT USING THE LATERAL FLARE HIP SYSTEM

To compare the early result of minimum incision surgery (MIS) to standard incision procedures with use of lateral flare hip replacement (Revelation Hip System, DJO, USA). 38 primary total hip arthroplasty of 36 patients were performed using lateral flare hip system. Lateral flare hip has symmetric contact to medial and lateral cortical bone at high proximal part and it provides definite endpoint of stem insertion. From this point of view, we can say that this system is suitable for MIS. Among the 38 hips, 21 hips were performed by MIS (less than 10cm) and 17 hips were performed by Standard incision. MIS were performed from November 2004 to December 2005. And Standard incisions were performed from June 2004 to December 2005. Two surgeons performed all operations (NW and YT). The main surgeon decided whether MIS was applicable or not for each patient. Anterolateral intra gluteal approach (modified Dall) was applied for all surgeries. The same rehabilitation program was applied on both groups postoperatively. The average follow-up period of MIS patients was 28.6 months and 34.7 months in standard incision. We investigated the early result of these patients. There was a relationship between patients’ height and the length of skin incision (p In the present study, intra-operative hemorrhage and operation time were significantly less in MIS group. It was supposed that at the patient selection, each surgeon decided the candidate of MIS due to patient’s hip condition. But in another situation, no significant difference was found for example in serum CRP, CPK and D-Dimmer levels. Clinical and radiological outcomes were not significantly different between MIS and Standard group in this study.
