Objective To report the clinical findings, diagnosis, treatment and outcome of equine patients with articular synovial cysts. Study Design Retrospective case series. Animals Horses (n = 16) with articular synovial cysts. Methods Horses diagnosed with articular synovial cysts (1988–2009) at 2 veterinary teaching hospitals were studied. Signalment, history, clinical signs, diagnostic methods and treatment were retrieved and telephone follow-up was obtained. Results Sixteen horses with articular synovial cysts were identified. Lameness was the reason for referral in most (n = 9) horses.

This case report describes the history, clinical findings, clinical pathology and diagnostic imaging of 2 cases of septic osteitis of the proximal sesamoid bones in foals. Treatment with doxycycline (10 mg/kg bwt per os b.i.d.) was successful in treating both of these cases.

The following report documents an unusual anatomical finding in two cases of aseptic tenosynovitis of the digital flexor tendon sheath. Disruption of the vinculum attachment between the palmar/plantar border of the superficial digital flexor tendon and the adjacent palmar/plantar annular ligament was identified in combination with other tendon pathology within the digital flexor tendon sheath. This tenoscopic finding has not been described previously in the literature.

The purpose of this report is to describe the clinical, imaging and pathological findings in a Quarter Horse colt admitted to the Texas A&M University Veterinary Medical Teaching Hospital for lameness of the left forelimb and left hindlimb. A presumptive diagnosis of left forelimb septic navicular bursitis was made ultrasonographically. A cyst-like lesion of the calcaneus was diagnosed radiographically and better characterised with computed tomography. The cyst-like lesion of the calcaneus was caused by infection with Actinobacillus sp.

Case Description—A 4-month-old Standardbred colt was examined because of a fractured right calcaneus of 8 days' duration with increased distraction of the fracture fragment evident on sequential radiographs. Clinical Findings—The foal was severely lame with diffuse periarticular tarsal swelling. Radiographically, a complete, displaced long oblique fracture of the right calcaneal body was evident. Because the fracture gap was increasing with time and lameness remained severe, despite medical management, surgical repair was recommended.

A yearling Arabian filly presented with a history of acute hindlimb lameness, marked tarsocrural effusion and associated soft tissue swelling and was diagnosed with fractures of both the lateral and medial malleoli of the distal aspect of the tibia. The fractures were repaired using a combination of cortical bone screws placed in lag fashion and a tension band wire. A full limb cast bandage was placed for recovery from general anaesthesia and the early post operative period.

The case report of a 14-month-old Thoroughbred filly with acute onset of severe right hindlimb lameness is presented. The horse had a severe and sudden abduction of the hindlimbs due to a side effect of an overdose of lidocaine, which had been administered in a constant rate infusion after a colic surgery. Transcutaneus ultrasonography and standing radiography of the pelvis revealed proximal and cranial displacement of the greater trochanter and free bone fragments consistent with an apophyseal avulsion fracture of the greater trochanter.

The case report presented here describes in detail the treatment and clinical progression of a case of severe chronic laminitis in a 10-month-old Arabian filly. Starting from the acute onset of clinical signs through the severe, debilitating progression of the disease, the report describes the medical, surgical and farriery treatment over a period of 8 months. The combination of deep digital flexor tendon tenotomy, hoof wall resection, corrective trimming and shoeing was successful in halting progression of the disease.

A variety of methods are described for managing distal limb flexural deformities in the foal, including intravenous oxytetracycline and splint or cast use. This case series describes a novel technique that creates an ‘active tension-extension splint’ by wiring the toe into a custom-made fibreglass splint and therefore into active extension. A dorsal fibreglass splint is made by halving a cast that is set around the affected leg with padding underneath it, so that it is sculpted to a more appropriate anatomical shape.

An 8-year-old Polo pony mare was admitted for investigation of lameness related to swelling of the elbow. An intra-articular fragment from the proximo-medial radius was identified on radiographic examination. The fragment was removed arthroscopically under general anaesthesia via a caudo-medial approach to the elbow joint.
