In Thoroughbred (TB) racehorses right C-3 fractures are more common, whereas in Standardbreds (STB) the distribution is nearly equal. Horses with slab fractures of the central or third tarsal bone are usually very lame immediately after the injury, but improve considerably after a few days. Types of fractures. Traumatic fractures are further classified as occurring with or without displacement of fragments and as being oblique, transverse, or comminuted. We are looking at the tooth at an odd angle, actually toward the roof of the mouth with the mouth open, so you are seeing the chewing surface of the tooth. According to Ross, the prognosis for horses with the most common fractures–the condylar (distal aspect of the cannon bone) fracture–has become quite good, with the majority returning to racing. This technique is often performed using sedation and local anaesthesia, with the horse standing. There are many factors to consider when assessing the situation. The complex fracture was repaired, under the same anaesthetic period as the CT examination, using the CT Diagnosis and Surgical Treatment of Slab Fractures of the Third Carpal Bone Back to Table of Contents.

Spontaneous fractures involve a history of bone disease, while traumatic fractures do not; the latter type can be either closed or open, depending on whether there is an external wound. Fractures that extend from one articular surface to another articular surface. They’re generally classified as idiopathic, meaning the cause is unknown.

In the carpus, slab fractures occur in both frontal and sagittal planes. Martin G S, Haynes P F & McClure J R (1988) Effect of third carpal slab fracture and repair on racing performance in Thoroughbred horses - 31 cases (1977-1984). The right limb was affected more frequently than was the left limb (24 vs 7, P less than 0.05). The fanning technique of arthrodesis of the CMC joint may lead to fracture of carpal bones, joint instability, and MC joint subluxation. Slab fractures involve both the proximal and distal articular surfaces. The central tarsal bone (CT) was involved in 12 cases and the third tarsal bone (T3) in 8 cases. Slab fracture, C3, in a horse. Slab Fractures of Other Carpal Bones. Horse Journal Response: Fractures account for less than 1% of equine dental problems. An 18 g. spinal needle (3.5 in.) OBJECTIVE To report the diagnosis and surgical management of a dorsal slab fracture of the fourth carpal bone in a racing greyhound. Three horses were destroyed immediately after diagnosis, 2 failed to recover following surgical intervention and one remained lame and was destroyed after 3 months' rest. Try it and see. horses with slab fractures confirms that these teeth only infrequently develop infection later in life and therefore routine extraction of teeth with slab fractures is not indicated. A small fragment of bone that comes off of a bigger parent bone and remains in the joint space, usually due to high exercise . 7-8.

Answer this question: Martina Stuart: Depends which tooth size if slab angle of fissure etc etc. Radiographs showed a single large nondisplaced sagittal slab fracture; however, computed tomography (CT) revealed an additional small, displaced central tarsal bone fragment. Study design Retrospective case study. The most common fracture is a frontal slab fracture of the radial facet of the third carpal bone, followed by fractures of the intermediate facet and both facets of this bone. From developing new therapies that treat and prevent disease to helping people in need, we are committed to improving health and well-being around the world. Where the broken bone is located and its function is a large factor in recovery process. 2. a break in continuity of bone; it may be caused by trauma, twisting due to muscle spasm or indirect loss of leverage, or by disease that results in osteopenia. Seven horses recovered completely and returned to work following periods of rest ranging from 3 to 9 months. Each of the horses had a slab fracture of the third carpal bone that was treated surgically. It is important to differentiate true slab fractures from chip fractures, since surgical management and prognosis differ. Objectives: To report the outcomes of repair of uniplanar frontal slab factures of the third tarsal bone using a single 3.5 mm cortex screw in lag fashion. All fractures involved the articular surfaces of the intercarpal and the carpometacarpal joints in a frontal plane and had a cuboidal or slab shape. Objective To determine the prognosis for racing of horses surgically treated for slab fractures of the third carpal bone (C3).

Reasons for performing the study: A technique for minimally invasive repair of slab fractures of the third tarsal bone has not previously been reported. Decay is most often found in the upper-cheek teeth, which is also where most fractures occur. Typically, these fractures result from trauma incurred while the horse is pastured with other horses.
