Abstract
We studied the postoperative peroneal nerve palsy after high tibial dome osteotomy with the use of external fixation of Steinmann pins and Charnley clamp. Out of 74 operated knees, 24 suffered postoperative sensory or motor disturbance associated with the palsy of the peroneal nerve. In this paper, we assessed the relation between the incidence of postoperative nerve palsy and the distal pinning site, or the fibular osteotomy site or the correction angle. Our results were in accordance with the anatomical study performed by Kirgis et al. who pointed out the dangerous site for pinning or fibular osteotomy.
We concluded that the insertion of Steinmann pins, placed between 60 and 80mm distal to the lateral tibia plateau, may avoid postoperative deficit of the peroneal nerve.
