Fracture related ulnar and sciatic nerve transections: a report of two cases and literature review.

INTRODUCTION

Case reports, case series, and case control studies have looked at the incidence of complete nerve transection in the setting of fracture and the need for surgical exploration dating back to the 1920s. We present two cases of nerve laceration accompanying traumatic fracture with a thorough review of the literature.

METHODS

We used the following search terms: "ulnar nerve" OR "sciatic nerve" AND "laceration" OR "transection" AND "fracture." Results were reviewed and included for discussion if they specifically reported ulnar or sciatic nerve laceration accompanying traumatic fracture.

RESULTS

Our search yielded 15 papers reporting a total of 10 ulnar nerve lacerations and nine sciatic nerve lacerations. We present two additional cases. The first is a patient with a humerus fracture and complete ulnar nerve transection. The second case is a patient who suffered a femur fracture and complete transection of the sciatic nerve.

CONCLUSION

Nerve laceration accompanying traumatic fracture is rare. We review the reported cases of nerve laceration and present two cases treated at our institution. Though uncommon, nerve laceration should be considered in the setting of traumatic fracture with neurological injury, particularly open fractures.
