Hyperextension type tibial plateau fracture: A case report and literature review

Abstract

The report presents a case describing a very unusual hyperextension tibial plateau fracture, which is a small collapse of the front articular surface accompanied by injury to the posterior ligament and tendon and popliteal artery. The treatment of this fracture includes implantation of bone materials and anatomical reduction through rigid internal fixation, and symptomatic treatment of vascular injuries.

Worse Quality of Life Associated with Hyperextension Varus Tibial Plateau Fracture Pattern

“…However, the previous literature also supports the idea that there are some HEVTP fractures which may be unicondylar in nature. 9,18,20 For example, Chiba et al 17 evaluated 12 cases of hyperextension varus knee injuries that had anteromedial tibial plateau impaction with posterolateral complex and posterior cruciate ligament injuries but had no posterior tibial plateau cortical disruption. Similarly, 3dimensional advanced imaging and force mapping studies have demonstrated that the posterior tensile force in HEVTP injuries may not always involve the posterior articular surface.…”

“…Although the original description of the hyperextension varus fracture pattern only included bicondylar fractures, unicondylar fractures were also included because there is a subset of HEVTP fractures where lateral tension failure occurs through the proximal fibula or the lateral ligaments rather than through the posterolateral tibial cortex as originally described. 8,9,[17][18][19][20] (Fig. 1) This explains the discrepancy in current use of the terminology "Hyperextension Varus Tibial Plateau Fractures" (HEVTP) with that put forward by Firoozabadi et al, hyperextension varus bicondylar tibial plateau fractures.…”
