Objective—To evaluate equids with enostosis-like lesions (ELLs) and document the clinical and epidemiological features of this disease. Design—Retrospective case series. Animals—79 equids with a scintigraphic diagnosis of at least 1 ELL on ≥ 1 occasion. Procedures—Medical records of 4,992 equids that underwent bone scintigraphy between March 1997 and March 2009 were reviewed; 78 horses and 1 pony had a scintigraphic diagnosis of an ELL. For those equids, signalment; physical, scintigraphic, radiographic, and lameness examination results; and outcome were reviewed.

The aim of this study was to determine whether horses with a proximal palmar/plantar first phalangeal osteochondral fragment (POF) had comparable racing careers (prior to and following surgery) to horses without this fracture. A retrospective cohort study included 174 Swedish Standardbred trotters with osteochondral fragmentation in the palmar/plantar fetlock joint and 613 radiographically negative control horses presented for prepurchase examinations. Medical records and radiographs were examined for each horse.

An 18-year-old Warmblood stallion was presented for an acute onset nonweightbearing right hindlimb lameness following a mild lameness of 2 weeks' duration. Severe swelling was present in the right femoral area. Despite extensive diagnostic procedures, no definitive diagnosis could be made. Packed red cell volume was persistently low. The horse improved with supportive treatment and was discharged at the owner's request. The horse presented 4 days later for bleeding from a previously made incision on the lateral femoral area.

The aim of the study was to use spatial and multiple correspondence analysis (MCA) to describe and compare the regional proportion and spatial pattern of volumetric bone mineral density (BMDv) values within loaded regions of the plantar metatarsal epiphysis of young horses in race training. A single 2 mm transverse peripheral quantitative computed tomography ‘slice’, 10 mm proximal from the distal limit of the sagittal ridge of the distal metatarsal epiphysis was obtained from 14 2-year-old Thoroughbred fillies (7 exercised and 7 controls).

Summary Reasons for performing study Accurate radiological and ultrasonographic descriptions of frontal plane fractures of the accessory carpal bone (ACB) are lacking, and implications of these fractures for the carpal sheath and its contents have not previously been reported.

Summary
Reasons for performing study

Radiography is commonly used in clinical practice but agreement of reporting of radiographically detected orthopaedic findings in horses has rarely been studied.
Objectives

To assess agreement within and between observers for reporting of orthopaedic findings on presale radiographs of Thoroughbred yearlings.
Study design

Retrospective analysis of archived radiographs.

Summary
Reasons for performing study

The occurrence of bucked shins in young Thoroughbred racehorses in North America is high. Although an altered training regime has demonstrated a significant decrease in this condition, trainers can be opposed to altering something as fundamental as their training routine. Periosteal scraping of the third metacarpal bone (McIII) is a putative prophylactic technique used to prevent bucked shins; therefore, a study to investigate the validity of the procedure is warranted.

Two Quarter Horses were examined at the Washington State University Veterinary Teaching Hospital with forelimb lameness. Case 1 was a 4-year-old female with a 4 month history of intermittent forelimb lameness that had partially responded to oral anti-inflammatories. The horse was in full training and actively competing in cutting. Case 2 was a one-year-old filly bred for cutting that presented with a right forelimb lameness of 3 weeks’ duration, which was not responsive to oral anti-inflammatories. The horse was not in training.

Bisphosphonates (BPs) are drugs widely used in various bone diseases, mainly for their skeletal antiresorptive effect. Nowadays, they are also used to treat degenerative pathologies such as arthritis because of their particular anti-inflammatory and analgesic properties. Since the sixties, BPs with different characteristics and biological activity profiles have been studied, although most of the pharmacologic and clinical trials have been carried out in humans. By 2002, however, tiludronate was granted a marketing license in France for use in horses.

Summary

Reasons for performing study

Lysis of the axial aspect of equine proximal sesamoid bones (PSBs) is a rare condition reported to have septic or traumatic origins. Limited information exists regarding imaging of nonseptic axial osteitis of a PSB.
