- See:- Femoral Neck Frx
- Discussion:
- these injuries occur from high energy trauma and comprise 1-6% of all femoral shaft frx;
- in up to 20% of cases, this injury is missed, which is often due to failure to take good quality femoral neck radiographs (often the hip is externally rotated which may obscure the fracture line);
- risk factors for femoral neck/shaft fractures include the presence of acetabulum and patellar fracture;
- when there is a question of a femoral neck fracture consider a CT scan of the femoral neck;
- in the retrospective series by Yang KH, et al, 6 of 8 undisplaced femoral neck fractures were shown to be present before operation (two fractures were iatrogenic);
- Fracture of the ipsilateral neck of the femur in shaft nailing. The role of CT in diagnosis.
- Treatment Options:
- priority should be given to anatomical reduction & rigid fixation of the fracture of the neck;
- if feasible, both fractures should be rigidly stabilized, with closed interlocking nailing being preferred for the fracture of the shaft;
- retrograde nailing of femoral shaft fractures:
- main disadvantage is possible knee stiffness;
- plating of femoral fractures
- miss a nail technique:
- main disadvantages involve the influence of the nail interfering with the reduction and interfering with the femoral head blood supply which might increase the chance of AVN
