Triplane Fracture Review Lapner Nov 2010
Objectives • Background • Epidemiology • Pathophysiology • Diagnosis • Treatment • Closed • Open • Management
History • Poland 1898, first detailed description • fracture meets a 3-plane geometry • transverse • sagittal • coronal
S-H classification • defies simple Salter-Harris system
Epidemiology • distal tibia second most common site of epiphyseal injury • what is the first? • 10% of pediatric intra-articular ankle injuries • higher incidence in boys • later closure of lateral tibial growth plate
Pathophysiology • characteristic asymmetric closure of physis • central/anteromedial lateral physis • degree injury based on ossification/energy • “Kump’s hump”
interesting notes • 12-15 years old • transitional fracture • limited dorsiflexion < 10° • predisposes ankle injury sports • fibula fractured 50%
Diagnosis • CT important • planning • diagnosis • displacements
Treatment • Closed • < 2 mm displacement (1mm?) • < 3 mm initialy displacement indication of OR? • extraarticular amenable to non-operative rx
RIF • differing approaches • anterolateral (lateral fractures) • anteromedial • arthroscopic assisted • > 2 mm displacement • long term FU data suggest increased risk degeneration • anatomic reduction reduces risk of physeal injury
RIF method • anterolateral fragment addressed 1st • reduced through AL approach • posteromedial fragment reduced next • (DF IR foot) • AP screw affixing posterior fragment
Post-Op • long leg cast for 3 weeks • short leg cast with progressive weight bearing.
