Avulsion fractures from the distal border of the navicular bone are relatively common, but normally of little clinical significance. Other fractures are uncommon and have a poor prognosis. Surgical fixation of parasagittal fractures (lag screw) is technically quite difficult, but potentially improves the prognosis for return to work to about 80%. If surgical fixation is not possible, then farriery to raise the heels of the foot may be of benefit.

Musculoskeletal injury is the most common cause of lost training days in the young Thoroughbred horse in flat race training. To date, there has been little investigation of the regional patterns of injury frequently observed by clinicians in racehorse practice. The present study was conducted to determine incidence of musculoskeletal injuries in Thoroughbreds in training in Newmarket, United Kingdom. Veterinary records for all horses resident in three large (>100 horse) training yards were assessed for occurrence of significant musculoskeletal injury.

The objective of this study was to describe the use, and outcome, of multipotent mesenchymal stromal cells (MSCs) in the treatment of equine articular cartilage defects of the medial femoral condyle. A 4-year-old Thoroughbred gelding (n = 1) with bilateral stifle athroscopy was found to have bilateral articular cartilage fissure defects of the medial femoral condyles with concurrent cranial cruciate ligament injury. Bone marrow derived MSCs were isolated, expanded, and suspended in a partially autologous fibrin glue.

Penetrating injuries of the foot are extremely common in equine practice. Most are managed conservatively with generally a good prognosis but there is always the concern that any foot penetration can have the potential to involve deeper structures resulting in life-threatening complications. It is therefore essential that the veterinarian has a sound working knowledge of anatomy and understands the risks of potential sequelae from the earliest possible moment.

A 4-year-old Quarter Horse gelding with a history of acute trauma was presented to our faculty. This report describes the inciting injury, documented in a video, and the ultrasonographic diagnosis of a traumatic extrusion of the right lateral meniscus with an accompanying extra-articular hematoma and distal collateral ligament lesion in a competing Quarter Horse. The ultrasonographic diagnosis of a lateral meniscal injury directly correlated with postmortem findings and this type of lateral meniscal injury has not been previously described in detail.

Two fillies with hindlimb lameness and a tentative diagnosis of a pelvic fracture involving the acetabulum were examined using computed tomography (CT). The use of CT for these two cases revealed the exact course of the fractures and fissures, as well as the size and position of fragments, thus allowing for definitive diagnosis.

Objective: To evaluate whether wound type or site influence the production of cartilage oligomeric matrix protein (COMP) and transforming growth factor β1 (TGF-β1), and determine if there is a correlation between TGF-β1and COMP during healing.

Study Design: Experimental.

Animals: Standardbred horses (n=6), 4–8 years old.

Objective: To describe the diagnosis and treatment of fractures of the deltoid tuberosity. Study Design: Case series. Methods: Medical records (1992–2009) of 19 horses with radiographic confirmation of deltoid tuberosity fractures were reviewed. Data retrieved included signalment, clinical and diagnostic imaging findings, and treatment. Outcome was determined by telephone questionnaire of owners and referring veterinarians. Results: Most horses were markedly lame on admission and 53% had reduced protraction of the affected limb.

A retrospective analysis of 15 cases of flexor tendon lacerations managed with a fetlock support brace between 2004 and 2008 was performed. Information was gathered concerning exact nature of the injury, treatment details and outcome. Limbs involved included 2 forelimbs and 13 hindlimbs. Eight of fifteen horses (53%) presented with a dropped fetlock, elevated toe or both when bearing weight on the affected limb. General anaesthesia was performed on 7/15 cases to further evaluate and treat the wound, 8/15 cases were managed with local anaesthesia and/or sedation only.
