Schatzker classification of tibial plateau fractures
Type 1: Lateral tibial plateau - split, no depression
Type 2: Lateral tibial plateau - split with depression
Type 3: Lateral tibial plateau - depression only
Type 4: Medial plateau split and/or depressed
Type 5: Medial and lateral tibial plateau, metaphysis in continuity with diaphysis
Type 6: Medial and lateral tibial plateau & subcondular tibial fracture with separation of metaphysis from diaphysis
Most anterior ethmoid air cells. Can pneumatise posteriorly to narrow frontal recess
Agger Nasi cells
Post THR, focal radiolucencies around the prosthesis with zsmooth endosteal scalloping
Histiocytic response
Multiple skin lesions, unilocular cystic lesion in mandible
Gorlin Goltz, Odontogenic keratocyst
