Comminuted Femoral Shaft Fractures – Type IV

- Discussion:
- see: Winquist Classification
- sign of high energy trauma: more blood loss, systemic complications, and fat embolism syndrome;
- all cortical contact is lost;
- simple cloverleaf nails are contraindicated w/ type III and IV comminuted frxs because of risk of shortening of frx about nail;
- small diameter nails fail to fill the canal, allowing even type I and type II comminuted frx to telescope about the nail;
- even with IM nailing, there will be no cortical contact between the proximal and distal fragments;
- static locking of the major fracture fragments prevents postoperative shortening and malrotation of the fracture;

- Reaming Considerations:
- if there is a segmental bone loss or comminution in shaft, reamers should be pushed, not powered, across the defect
to avoid damage to the soft tissues of the thigh;

- Leg Length Considerations::
- clinical measurement of contralateral femur from tip of greater trochanter to the lateral aspect of the knee joint provides
useful landsmarks for the correct leg length;
- special varient of comminuted fractures, the segmental fracture, involves a double level fracture of the shaft;
- preoperative measurements of femoral length and nail length are needed
