Axial osteitis of the proximal sesamoid bones and desmitis of the intersesamoidean ligament has been described in Friesian horses as well as in other breeds. The objectives of this study were to review the outcome of clinical cases of this disease in Friesian horses and analyse the pathology of the bone-ligament interface. Case records of Friesian horses diagnosed with axial osteitis of the proximal sesamoid bones and desmitis of the intersesamoidean ligament in the period 2002-2012 were retrospectively evaluated. Post-mortem examination was performed on horses that were euthanized (n = 3) and included macroscopic necropsy (n = 3), high-field (9.4 Tesla) magnetic resonance imaging (n = 1) and histopathology (n = 2). Twelve horses were included, aged 6.8 ± 2.7 years. The hindlimb was involved in all cases. Lameness was acute in onset and severe, with a mean duration of 1.9 ± 1.0 months. Three horses were euthanized after diagnosis; 9 horses underwent treatment. Two horses (22%) becam...

Objective: Equine models of osteoarthritis (OA) have been used to investigate pathogenic pathways of OA and evaluate therapeutic candidates for naturally occurring equine OA which is a significant clinical disease in the horse. This review focuses on the macroscopic and microscopic criteria for assessing naturally occurring OA in the equine metacarpophalangeal joint as well as the osteochondral fragmentexercise model of OA in the equine middle carpal joint. Methods: A review was conducted of all published OA studies using horses and the most common macroscopic and microscopic scoring systems were summarized. Recommendations regarding methods of OA assessment in the horse have been made based on published studies. Results: A modified Mankin scoring system is recommended for semi-quantitative histological assessment of OA in horses due to its already widespread use and similarity to other scoring systems. Recommendations are also provided for histological scoring of synovitis and macroscopic lesions of OA as well as changes in the calcified cartilage and subchondral bone of naturally occurring OA. Conclusions: The proposed system for assessment of equine articular tissues provides a useful method to quantify OA change. It is believed that addition of quantitative tracing onto plastic and macroscopic measurement as recently described would be an improvement for overall assessment of articular cartilage change.

Osteoarthritis of the proximal interphalangeal joint (PIPJ) is a common cause of chronic lameness in the horse that requires surgical arthrodesis when medical management is no longer able to alleviate pain. Surgical principles for successful PIPJ arthrodesis include articular cartilage debridement and rigid fixation. To completely debride articular cartilage, the collateral ligaments and extensor tendon are transected, disarticulating the joint. The purpose of this study was to demonstrate that in chronically lame horses with periarticular new-bone formation and osteoarthritis, successful arthrodesis occurs without joint disarticulation and complete ar-ticular cartilage debridement. We hypothesised that complete articular debridement is not necessary, thus allowing for a less invasive surgical approach that decreases surgical time and hospitalisation with comparable success rates to previous reports. Medical records from 2000-2007 were reviewed for PIPJ disease. Information regarding lameness, surgical time and hospitalisation were retrieved from 11 horses (12 limbs). Follow-up information was obtained via a telephone interview and a re-evaluation. Average hospital and surgery times were shorter than previous reports at 19 days and 111 minutes respectively. Lameness decreased at least one grade in 92% of limbs. 73% of owners would elect to operate again. The data suggests that successful arthrodesis occurs without joint disarticulation and complete articular cartilage debridement.

Aims: To describe the radiographic appearance and location of facet joint lesions, the clinical signs and to determine if there was any breed, gender, age, bwt or discipline predilection. Methods: Data from 77 horses examined at the Animal Health Trust between January 1997 and September 2007 with evidence of thoracolumbar pain and radiographic changes of the facet joints were reviewed. The presence of either other osseous abnormalities of the thoracolumbar region or other problems potentially contributing to poor performance were recorded. Facet joint lesions were graded radiographically and their location determined. Influence of breed, gender and discipline on the presence of lesions, effect of location on the type of lesion and the influence of impinging dorsal spinous processes on the clinical features were assessed using Chi-squared tests. Results: There was no effect of breed, gender, age or bwt on prevalence of facet joint lesions. Showjumpers were less affected than horses from other disciplines (P<0.0001). There were commonly 2-5 affected facet joints, usually in the caudal thoracic and cranial lumbar spine (T15-L1). Sclerosis, periarticular new bone and narrowed joint space were the most frequent radiographic lesion types. Clinical features were different between horses with and without impinging dorsal spinous processes (P<0.0001). Conclusions and Practical Significance: Osteoarthritis of the facet joints of the thoracolumbar spine can occur alone in horses with back pain, or in association with other osseous abnormalities. Severity of clinical signs was related to the presence of other osseous abnormalities, not the number of facet joints involved or the severity of lesion type. Further investigation of the prevalence of osteoarthritis in horses without clinical signs of back pain is merited.

The prevalence of osseous fragments in different limb joints was analysed in 3749 young Warmblood riding horses, which were pre-selected for sale at auction from 1991 to 1998 by the Association of Hanoverian Warmblood Breeders (Verband hannoverscher Warmblutzu¨chter e.V.) in Verden (Aller), Germany. The evaluation of these horses was based on a standardized radiological examination, including the distal interphalangeal (DIJ), the proximal interphalangeal (PIJ), the metacarpo-and metatarsophalangeal (MC/MTJ) and the tarsocrural joints (TCJ). In 32% of all horses at least one osseous fragment was found on these radiographs. TCJ were affected in 9.6% of the horses and MC/MTJ in 20.7%. The percentage of horses affected in the MTJ was significantly higher (13.7%) than that of horses affected in the MCJ (9.5%). The prevalences of osseous fragments were considerably lower in DIJ (4.5%) and PIJ (0.9%). Osseous fragments only occurred either in DIJ or PIJ or MC/MTJ or TCJ in 87% of the affected horses. Depending on the joint type, osseous fragments were found in analogous joints in the front and the hind limbs in up to 26% of the affected horses, whilst bilateral affection occurred in between 10% and 46% of the horses. Distribution of osseous fragments in the limb joints investigated here did not differ significantly between male and female horses. There was a significant increase in the percentage of horses with osseous fragments in MC/MTJ during the study period. The results of this study indicate the need to act against the high prevalences of osseous fragments in the limb joints of young Warmblood riding horses. U.S.
Acropodial Diseases in Horses Diagnosed Radiographically: Retrospective Study of 7 Cases
The lameness associated with pain localized within acropodial region is common in horses, which enforces the use of radiological equipment in tracking changes in bone level as well as in adjacent soft tissues level. The most common acropodial diseases are represented by traumatic processes, followed by degenerative and infectious, which can envolve acute or chronic. The purpose of this study was describing semiological aspects noticed in radiological examination of acropodial region in horses. Radiographic images from animals with acropodial diseases were selected and examined inside the radiology clinic inside the Faculty of Veterinary Medicine Bucharest. The assessment of radiological images has revealed changes in acropodial level in 7 horses, ages varying between 8 months and 11 years, of which 4 males and 3 females. Acropodial changes were represented by 3 cases with middle phalanx fracture and the rest with: with: distal interphalangeal luxation, degenerative processes of prox...
