+===Types===
-*Do not confuse a bipartite patella with a fx

-*Imaging
+*[[Tibial plateau fracture]]
-**AP and lateral
+*[[Segond fracture]]
-**Consider skyline (sunset) view if suspect fx of articular surface
-*Positioning
-**Lateral view: Distance from tibial tubercle to lower pole of patella ~ length of patella +/- 20%
-***If > than this suspect patellar ligament rupture
-==Fibular Neck Fx==
+==Differential Diagnosis==
-*Often associated w/ severe knee injury including damage to collateral and cruciate ligaments

+==References==
-===Background===
+<references/>
-*Medial condyle + intercondylar eminence + lateral condule
-**Intercondylar eminence is where ACL attaches
-*Ligamentous and meniscal injuries are common
-*Compartment syndrome may occur
-*Segond's Fracture
-**Avulsion fx of margin of lateral tibial plateau just below joint line
-**Has strong association with tear of ACL and meniscal ligaments
-===Diagnosis===
+[[Category:Orthopedics]]
-*TTP
-*Knee effusion
-===Work-Up===
-*AP, lateral
-**AP - line drawn at lateral margin of femur should not have >5mm of tibia beyond it
-*If suspicion high but xray negative consider MRI or CT
-===Management===
-*Plateau Fracture
-**RICE
-**Splint in full extension
-**NWB
-===Disposition===
-*Indications for referral within 48hr:
-**Significant displacement or depression
-**Suspected or documented ligamentous injury
