possible complications?
|a3=
The fracture should be anatomically reduced and stabilized with a transcondylar screw placed in lag fashion. In this dog, additional screws were placed in the epicondylar region to provide adjunctive stability.
This fracture may not heal because the lateral and medial portions of the condyle were never united. Therefore, the lag screw
must provide rigid stabilization for a prolonged period of time.
In one case series, 23% of dogs had complications following surgical repair of condylar fractures.
The screw may loosen, resulting in pain, or break, resulting in failure of stabilization. When possible, a 4.5 mm cortical bone screw should be selected as this screw has 2.5 times the resistance to bending when compared with a 3.5 mm cortical screw.
The contralateral condyle should also be evaluated. If incomplete ossification is present, the potential for fracture of the contralateral condyle exists.
