Abstract
Introduction
Recent evidence suggests use of lateral femoral distractor (LFD) to aid in visualization during surgery for tibial plateau fractures (TPF) may result in an unacceptably high rate of iatrogenic peroneal nerve palsy. We sought to evaluate femoral distractor use for open reduction internal fixation (ORIF) of TPF and quantify the incidence of peroneal nerve palsy.
Methods
We retrospectively evaluated all patients undergoing ORIF of TPF between 2014 and 2019 by a single fellowship trained orthopaedic traumatologist at a single Level 1 trauma center. Inclusion criteria were use of a LFD during ORIF of TPF. Exclusion criteria were preoperative neurovascular injury in the operative extremity and distraction via pre-existing external fixator. Parameters included patient demographic variables, intraoperative techniques, postoperative outcomes, and fracture classification. Documented clinical exam was used to evaluate peroneal nerve status and injuries were classified as complete or incomplete. Incomplete injuries were classified as sensory or motor.
Results
Of 303 patients undergoing ORIF for a TPF, femoral distraction was used in 254 (83.8%) cases, with 201 utilizing applied intraoperative femoral distraction and 53 utilizing pre-existing knee-spanning external fixation for distraction. Three patients were excluded for preoperative sensory peroneal nerve palsy with 175 patients meeting inclusion criteria. The most common fracture type was lateral split depression (n = 130). Zero patients developed complete or incomplete peroneal nerve palsy.
Discussion
Our study found no incidence of peroneal nerve palsy when using lateral femoral distraction. This study supports the utilization of lateral distraction for articular visualization and reduction during ORIF of TPF.
