Abstract:
In this study, interleukin-6 (IL-6), C-reactive protein (CRP), and haemoglobin levels were evaluated to compare the degree of surgical invasion between mini and standard incisions in total hip arthroplasty (THA). Sixty-two patients admitted for primary cementless THA were enrolled in this randomised study. The patients were allocated to have surgery through either a mini incision of <10 cm or a standard incision of 15 cm. In each group, inflammatory responses were evaluated by IL-6, CRP, and haemoglobin levels before operation and one day after operation. Significant differences were not found in IL-6, CRP, and haemoglobin levels between both groups. At six months after surgery, there were no significant differences in postoperative Harris hip scores or radiographic evaluations between both groups. In conclusion, a 5.0 cm difference in the skin incision to the hip joint seemed to have no influence on the degree of surgical invasion during THA.
