Introduction. Account for 7% of all femur fractures. Bimodal distribution: High-energy injuries in the young, low-energy in the elderly. Historical treatment. 1960’s and earlier: Skeletal traction favored. Neer et al. (JBJS 1967) advocated for closed, non-operative treatment based on poor results and high complications resulting from ORIF.
Distal femur fractures are traumatic injuries involving the region extending from the distal metaphyseal-diaphyseal junction to the articular surface of the femoral condyles. Diagnosis is made radiographically with CT studies often required to assess for intra-articular extension.
These modalities, each with their own merits and drawbacks, range broadly from external fixation, fixed-angle device (blade or sliding barrel implants), plate fixation (locked and unlocked), intramedullary nailing, arthroplasty, and distal femoral replacement (DFR) (Box 1).
Identify the etiology of distal femur fractures. Review the appropriate history, physical, and evaluation, including correct imaging and classification of distal femur fractures. Describe the treatment options and common complications with surgical management for distal femur fractures.
Diagnostic Procedures. Clinical/Physical examination: the typical clinical picture during the inspection of the knee is pain of distal femur that is made worse with knee movement and inability to weight-bear. Radiographic examination: AP and lateral views of the femur.
Introduction. Goals of Treatment. Anatomic reduction of the articular surface. “functional” reduction of the metaphysis restoring length, alignment, and rotation. Stable fixation. Early range of motion. Potential road blocks. Poor bone quality. Comminution.
The goal of clinical management of distal femoral fractures is the anatomic reduction of the articular surface and restoration of limb length, rotation, and alignment. A stabile fixation construct is important to allow early knee range of motion to optimize functional recovery.
Microfracture is a surgical procedure performed to assist with cartilage regeneration. This procedure consists of the surgeon debriding any frayed tissue or flaps at the margin of the lesion. After this, the calcified chondral layer is debrided to expose the underlying subchondral bone.
Gerdy's tubercle osteotomy approach to the distal femur. Connect with peers, learn from experts. Dec 1–12, 2024.
Introduction. Distal femur fractures are fractures extending from the distal metaphyseal-diaphyseal junction of the femur to the articular surface of the femoral condyles. They account for around 3-6% of femur fractures.
