Near-Complete Transection of the Sciatic Nerve After Closed Reduction Attempt of a Dislocated Total Hip Arthroplasty

Sciatic nerve injuries are rare and devastating complications that can occur following total hip dislocations. These injuries are even more uncommon when resulting from a closed reduction attempt. In the literature, only one other case of sciatic nerve palsy secondary to sciatic nerve laceration has been reported. Conducting a careful neurovascular examination following a closed reduction procedure is crucial in determining the presence of sciatic nerve injury. We present a case of sciatic nerve palsy following a closed reduction attempt of a dislocated total hip arthroplasty (THA). Surgical exploration revealed a near-complete sciatic nerve laceration. The patient subsequently underwent neurolysis and nerve repair. This case highlights the importance of thorough neuromuscular examination following closed reduction of THA, with consideration for surgical exploration when necessary.
