This retrospective study asked whether it matters if a definitive plate is placed over a previous external fixator pin site during staged fixation of high-energy tibial fractures. 182 patients with OTA 41C tibial plateau and 43C pilon fractures were divided into overlapping and non-overlapping groups based on postoperative radiograph review. The primary outcome was deep wound infection requiring surgical debridement.
The two-stage protocol for high-energy tibial plateau and pilon fractures is now standard, but the placement of the provisional external fixator has downstream consequences that are easy to overlook in the acute setting.
When you place an external fixator on a tibial plateau or pilon fracture, you must think prospectively: where will the plate go? Pins placed in the future plate zone carry a 24% deep infection risk vs 10% otherwise. That is a modifiable risk factor you control in the first operation.
For patients referred from outside institutions with an external fixator already in place, evaluate pin positions relative to your planned implant zone before the definitive case. If there is overlap with your intended plate, consider revising the pin sites.
Smokers are already at higher infection risk (60% of infected patients in this series). A smoking patient with pin-plate overlap represents a convergence of two independent risk factors — your plate length decision carries real consequences in that patient.
