Distal femur fracture is 9cm inside femur, including the condyle and intercondylar fractures. Its incidence accounts for 4% of all fractures of the femur. Due to the characteristics of the fracture site bone structure. The fracture is mostly unstable and comminuted. Difficult to be firmly fixed, fractures is near the knee, spread to the articular surface, which is likely to affect the knee, being one of the most difficult to treat fractures.
Non-surgical treatment
It is applicable to relatively stable fracture. Using tibial tubercle traction until bone fracture healing, usually six to eight weeks of traction. Turn attention to prevent fracture segment, valgus or rotational deformity, but the outcome is often unsatisfactory.
Surgery
1. nail plate fixation. Commonly dynamic condylar screw, 95 ° angle plate, condylar buttress plate, LISS fixation system. Suitable for adult femoral condyle stable and unstable fractures, old fractures and fracture healing.
2. Lag screws.
3. Condylar plate fixation.
4. Retrograde intramedullary nailing.
5. External fixation.
1. pediatric suspension traction
Parents should always check the children's two feet and abnormal blood circulation, preventing complications; being ready to touch the feet of children with temperature observed toe color.
2. adult postoperative functional exercise
(1) 7-10 days after surgery, the patient initiatively can do hip and knee flexion and extension on the bed. Action should be gentle, smaller magnitude, not overexert.
(2) 30 days after surgery, patinets can get out of bed to walk with crutches. Limb can touch ground, but it is still unable to bear weight.
(3) 2-3 months after surgery, do X-ray examination. If the fracture has healed, patients can walk with weight-bearing with crutches.
(4) 4 months after surgery, normal walking can be acceptable.
