Dr. Wahby Ghalib CABMS, FJMC, MRCSSupracondylar femoral #
Last 10 – 15 cm of femurClassification
Extraarticlar Intraarticular unicondylar Intraarticular bicondylarXR
# may be T- or Y-shaped # may be in the coronal plane (Hoffa #)
# may tilt posterior by gastrocnemius compression of popliteal vessels & tibial nerve

Tibial plateau #
MechanismVarus force Valgus force Axial load
Classification (Schatzker)
1 : vertical split of lateral condyle 2 : vertical split + depression of lateral condyle 3 : depression of lateral condyle 4 : medial condyle # 5 : bicondylar # 6: condylar + subcondylar #Lateral condyle # more common than medial Type 1 : occurs in young Type 3 : occurs in elderly Type 3 : is the commonest

Vascular injury Compartment s. Specially 5 & 6 Nerve injury : common peroneal Deformity Joint stiffness OA
Patellar #
PatellaBiggest sesamoid bone in the body Improves the lever of the quadriceps The quadriceps inserts to the tibia via the patellar tendon & extensor retinacula
Mechanism
Direct : e.g. dashboard Indirect : forceful contractionTypes
Undisplaced crack Stellate ( comminuted) # Displaced transverse #DDx
