Lateral Tibial Plateau with Peroneal Nerve Entrapment is Unique Fracture in Diagnosis and Management
Tibial plateau fractures account for 1-2% of all fractures and
are caused by a valgus or varus force and axial loading at the knee.
The varying direction and magnitude of forces applied and
pre-existing quality of patient’s bones results in a wide spectrum
of fracture patterns.
Hohl et al reported that 55-70% of tibial
plateau fractures involve the lateral plateau and about 7% involve
the posterolateral tibial plateau.
Tibial plateau fractures are classified by either the more
complex and precise Arbeit gemeinschaft für Osteosynthesefragen/
Orthopaedic Trauma Association (AO/OTA) system or the
more reproducible and reliable Schatzker method.
For the AO/ OTA system, the proximal tibia is coded as a 41 with
further subgroupings based on intra-articular fractures with B1-3 for partial
and C1-3 for complete involvement.
The Schatzker method divides tibial plateau fractures into 6 types: 1) split fracture of the
lateral plateau; 2) split depression of the lateral plateau; 3) central
depression of the lateral plateau; 4) split of the medial tibial plateau;
5) bicondylar tibial plateau fracture OR; 6) tibial plateau fracture
with dissociation between the metaphysis and diaphysis.
