Abstract

The aim of this research is to compare and determine the accuracy and iatrogenic sciatic injury possibility of two hip joint surgical approaches to perform Toggle Pin Fixation technique. Twenty joints (ten dogs cadavers) will be shared in Group I - ten hip joints, Toggle pin Fixation technique performed by greater trochanter osteotomy approach and Group II - ten hip joints, Toggle Pin Fixation technique performed by craniolateral approach. The one and the other procedures will be performed in each cadaver. The distance between the holes realized and the round ligament attach on femoral head and acetabulum will be measured to evaluate the accuracy of the techniques. The distance between the incised periarticular soft tissues and the sciatic nerve will be determined to evaluate the probability of the nerve injury. The hip joint range of motion measurement will be done before and after the surgery. We hypothesized that the accuracy to execute the Toggle pin Fixation technique is similar when performed by standard or by craniolateral approach. In addition, we suppose that the standard approach will have more chance to promove iatrogenic sciatic injury. The results will be evaluated by statistic tests. (AU)
