Talus: Sagittal fractures

Fracture characteristics

Sagittal fractures are usually caused by twisting forces and are mostly closed.
They usually cause very severe lameness.

Sagittal fractures of the talus

These fractures displace only minimally and are therefore difficult to detect radiographically. Computed tomography is the imaging technology best suited for a detailed diagnosis, which is a prerequisite for proper screw placement.

Sagittal fractures of the talus

Incomplete sagittal fractures of the talus are rare and according to Davidson et al., the left talus is more commonly affected.

Fractures of the talus

Talar fractures can occur after an external trauma or after twisting or shearing of the tarsus. They vary from simple fragmentation of small portions of the trochlear ridges...,

Clinical signs and imaging

Clinical signs can vary considerably, but very often horses show an acute severe weight bearing lameness (Grade III to V). Significant effusion of the talocrural joint is seen with most fractures of the talus. Fissures can be difficult to find radiographically. Therefore, several projections with different angles including flexed and skyline projections of the tarsus are necessary.
CT imaging is very useful to detect fissure lines and help to understand the configuration of the fracture.
