Tổn thương thần kinh XẢY RA trong 1% đến 2% bệnh nhân trải qua arthroplasty khớp háng là ai và thường xuyên hơn ở những bệnh nhân có nhu cầu tái thiết acetabular cho chứng loạn sản và sửa đổi Những arthroplasty Trải qua. Chấn thương ở bộ phận mác của các dây thần kinh hông | Nerve Injuries in Total Hip Arthroplasty Marc M. DeHart MD and Lee H. Riley Jr MD Abstract Nerve injury occurs in 1 to 2 of patients who undergo total hip arthroplasty and is more frequent in patients who need acetabular reconstruction for dysplasia and those undergoing revision arthroplasty. Injury to the peroneal division of the sciatic nerve is most common but the superior gluteal obturator and femoral nerves can also be injured. Nerve injury can be classified as neu-rapraxia axonotmesis or neurotmesis. The worst prognosis is seen in patients with complete motor and sensory deficits and in patients with causalgic pain. Prevention is of overriding importance but use of ankle-foot orthoses and prompt management of pain syndromes can be useful in the treatment of patients with nerve injury. Electrodiagnostic studies hold promise in complex cases however their intraoperative role requires objective prospective controlled scientific study before routine use can be recommended. J Am Acad Orthop Surg 1999 7 101-111 Nerve injury after total hip arthroplasty THA can be a devastating complication. Upper-extremity nerve-traction palsies related to positioning have been reported with a higher incidence of ulnar nerve damage in arthroplasty patients with inflammatory Obturator nerve injuries are exceedingly uncommon but have been the subject of case reports. Superior gluteal nerve and femoral nerve injury are relatively rare and in general have a better prognosis than sciatic nerve injuries. Most of the literature focuses on the peroneal division of the sciatic nerve. The physiologic demands as well as the structural anatomy of the nerves about the hip predispose these structures to injury during surgical procedures. In this article we will review clinical studies on the diagnosis treatment and prognosis of this infrequent complication and focus attention on the importance of prevention. Peripheral Nerve Anatomy and Physiology Nerves are uniquely designed to .
