Pin Leverage Technique: A Simple Percutaneous Technique for Elevation of Posterolateral Tibial Plateau Fractures.

Abstract

Depressed lateral tibial plateau fractures with a large central or posterior fragment can be seen in isolation or association with complex proximal tibia fractures. Conventionally elevation of the large depressed fragment is done by bone tamp through a medial metaphyseal window in isolated fractures, or the fractured window in associated complex fracture scenarios. Though various instruments have been devised for this purpose, reaching the posterior aspect of lateral condyle through the medial metaphyseal window is not always easy, considering the difficulty in aiming and trajectory. Excessive maneuvering can result in the widening of the medial metaphyseal window, leaves a large metaphyseal void, intraarticular penetration of elevating device, and comminution of the depressed fragment. Described herein is an alternate percutaneous technique for effective reduction of selected lateral tibial plateau depression fractures using Steinmann pin. Twenty- one patients with at least 1-year follow-up with successful outcomes have benefitted from this reduction technical tip thus far.
