- Distal Tibia Fracture:
- see: external fixation for distal tibia fracture
, outcomes of external fixation vs IM nailing
, and plate fixation
- w/ frx extension into the joint, consider placement of percutaneous lag screws to repair intra-articular fracture lines before
nailing is performed;
- guide wire:
guide wire needs to be directed towards the medial malleolus while the ankle is held in valgus;
- this will minimize the tendency for the fracture to drift into varus as the nail passes across the fracture site;
- blocking screws:
- antero-posterior blocking screws are inserted on either side of the central nail insertion zone inorder to effect an anatomic reduction;
- in general, the blocking screw is positioned where you don't want the nail to go;
- blocking screws are temporary, and therefore can be left 2 cm longer than needed for easy removal;
- with fracture demonstrating preoperative varus displacement, consider an antero-posterior blocking screw inserted on
medial side of distal fragment;
- this screw can be biased also in a medial to lateral direction to correct the recurvatum malreduction, or alternatively,
a second blocking screw, inserted from a medial to lateral direction in the anterior third of the tibia can be placed;
- blocking screw should remain as peripheral as possible (minimal blockage) in order to prevent iatrogenic comminution of
distal fragment at opposite end of frx;
- consider insertion of tip of nail 1 cm past frx site (barely across), and then inserting the blocking screw at a point tangential to
shaft of nail at same level as the tip of the nail (1 cm);
- as the nail is advanced the shaft will contact the blocking screw;
- need for 2 proximal and 2 distal interlocking screws;
- in the study by Isik, et al
(2012), the authors performed IM nailing with 2 distal and proximal screws on 34 patients, with no
post op complications;

- transfibular blocking screw
(as a temporary means of achieving reduction)
- instead of the classic blocking technique, a much easier technique involves percutaneous insertion of a 4.0 or 5.0 screw inserted
through the fibula;
- using percutaneous technique, insert a screw across the fibula until it engages the tibia.
- additional passage of the transfibular screw will begin to translate the distal tibial fracture site in medial direction;
- screw is advanced until it abuts the tibia, and then it is further advanced until the reduction is optimal;
- with soft bone, the screw may penetrate the cortex, but this is OK, because the screw will then continue to act as a blocking
screw against the nail;
- a second screw (inserted below the first screw) may also be required inorder to optimize the reduction;
- once the nail has been inserted and once interlocking screws are in place, the transfibular screws can be removed;
- ORIF of distal fibula:
- some authors recommend concomitant ORIF of the distal fibula
(if frx is present), inorder to improve rotational stability;
- 85 % of patients with malalignment after nailing do not have fibula fixation;
- there is some evidence (Attal R, et al
), that fibular fixation may lead to delayed union (8 fold higher risk of delayed bone healing);

- Case example:
82 year old male, who is about 5 weeks into cast treatment of a tibia fracture. Because of pain, fracture malreduction, and inability
to maintain a cast, IM nailing is chosen. The fracture was scarred into the malreduced position which required aggressive use of
polar screws to get the nail into proper position;
