Nerve palsy complications in artificial hip replacement / 中华创伤杂志

ABSTRACT

Objective To analyze the causes, prevention and treatment measures for nerve palsy complications in artificial hip replacement. Methods A total of 413 consecutive hip replacements performed from January 1991 to December 2001 were retrospectively studied. There were three cases of nerve palsy with a prevalence of 0.73%. Among them, there were two cases of sciatic nerve palsy and one femoral nerve palsy. Results The causes for nerve palsy in these three cases were hypotension shock due to excessive anticoagulation against deep venous thrombosis, hematoma compression and unknown causes respectively. The neuronal function of three cases of nerve palsy was recovered at different degrees through correction of shock, clearance of hematoma and rehabilitation therapy. Conclusions The causes for nerve palsy complication during artificial hip replacement are direct or indirect traction, compression and ischemia. Understanding the etiology of nerve palsy to avoid the nerve injury, immediate and correct management play an important role in prevention and treatment of nerve palsy during artificial hip replacement.
