INTRODUCTION: Nerve injury following total hip arthroplasty (THA) is a possible complication that is included in informed consent. Ninety-five percent of femoral artery catheterizations (FACs) utilize a right-side approach and can cause scar around the femoral nerve. The effect of FAC on femoral nerve injury during THA has not been investigated previously.
METHODS: The joint implant database was searched for patients who had primary THA after prior FAC from 2005-2015 (study group). Patients who underwent bilateral THA without prior FAC served as the control group. Proprietary software was used to query the database according to the International Classification of Diseases procedural codes for primary THA and FAC. Chi-square testing was used to determine significant differences between groups (p < 0.05).
RESULTS: There were 62,016 patients in the study group and 441,013 patients in the control group. The left femoral nerve injury rate in the control group was 0.53% and 0.55% in the study group. The right femoral nerve injury rate in the control group was 0.51% and 1.53% in the study group (p < 0.0001). A total of 91% were missed at the time of surgery but 69% of the femoral nerve injuries were identified within 90 days of THA.
DISCUSSION AND CONCLUSION: Patients with a previous history of right femoral artery catheterization have a significantly higher rate of right femoral nerve injury when undergoing THA. Orthopaedic surgeons should be aware of this increased risk of femoral nerve injury
