Overview
what it is and why it mattersDistal femur fractures occur in the metaphysis and condylar region of the femur immediately above the knee joint. They occur in two populations: young adults with high-energy trauma (fall from height, sports collision) where the bone is normal, and elderly osteoporotic patients where a low-energy fall breaks fragile bone. Periprosthetic fractures — fractures above a knee replacement — are a growing subset.
Diagnosis
exam first, imaging secondSevere knee pain, swelling, deformity, and inability to bear weight. AP and lateral X-rays of the knee and distal femur are the primary studies. CT scan with 3D reconstruction is used for comminuted intra-articular fractures to guide fixation planning.
Treatment Path
how care progresses at OSI1
Non-operative management
Traction or casting for non-displaced fractures in non-ambulatory patients or those with prohibitive surgical risk.
Surgical Options at OSI
if non-operative care isn't enoughMost displaced distal femur fractures require surgical fixation to restore the articular surface, allow early joint motion, and enable mobilization.
