Reasons for performing the study Lameness is prevalent in working donkeys and has major welfare implications; however, a detailed study of the associated clinical signs is lacking. Objectives To describe the range and prevalence of clinical signs and conformation associated with lameness in working draught donkeys. Study design Prospective, cross-sectional, observational study. Methods Data were collected from 102 working draught donkeys in Pakistan.

Summary

Reasons for performing study

Subjective evaluation of the response to diagnostic analgesia of hindlimb lameness is influenced by expectation bias. Quantification of pelvic movement with inertial measurement units is possible, but it is unclear which measure of movement symmetry best reflects the changes seen after diagnostic analgesia.

Reasons for performing study

Thus far, pressure-plate analysis has been limited to measurements on a hard surface, whereas equine athletes routinely perform on a deformable substrate.
Objectives

To explore pressure-plate analysis on arena footing.
Study design

Nonrandomised crossover study using noninvasive techniques.

Reasons for performing study To determine risk factors involved in survival to hospital discharge of cases of synovial sepsis. Objectives Investigate pre-, intra- and post operative factors involved in short-term survival of horses undergoing endoscopic treatment for synovial sepsis. Study design Retrospective case series. Methods Clinical data were obtained for horses (>6 months old) undergoing endoscopic surgery as part of management for synovial sepsis over a 7-year period in a single hospital population. Descriptive data were generated for pre-, intra- and post operative variables.

Reasons for performing study

Saddle slip is usually blamed on saddle fit, crooked riders or horse shape, but may reflect hindlimb lameness. There are no studies of the frequency of occurrence of saddle slip and risk factors within a tested sample population of the general sports horse population.
Objectives

To quantify the frequency of saddle slip and to describe the association with lameness, thoracolumbar shape/symmetry, crooked riders and ill-fitting saddles.
Study design

Nonrandom, cross-sectional survey using convenience sampling.

Infection of the cartilages of the foot is an uncommon condition, occurring usually secondary to wounds just above the coronary band. Effective treatment relies on surgical debridement of necrotic cartilage, but following this the prognosis for complete recovery is good.

Kinematic evaluation of the distal limb of the horse using standard methods is challenging, mainly due to the hoof capsule restricting visualisation, but the recent development of a high-speed fluoroscopy (HSF) system has allowed in vivo cineradiographic assessment of moving skeletal structures at high speeds. The application of this non-invasive method to the equine distal limb is used to describe ‘internal’ distal limb kinematics including intra-horse and inter-horse variability, and variability between walk and trot.

Cartilage regeneration with cell therapy following arthroscopic surgery could be used in racehorses with intra-articular fractures (IAF) and osteochondritis dissecans (OCD). The aims of this study were to investigate the origin and multipotency of stromal cells in the synovial fluid (SF) of horses with intra-articular injury and synovitis, and to provide a new strategy for regeneration of lost articular cartilage. Mesenchymal stromal cells were isolated from SF of horses with IAF and OCD.

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.

Objectives: 1) To evaluate the bacteriostatic in vitro effect of pure platelet-rich plasma (P-PRP), pure platelet-rich gel (P-PRG), leukocyte-poor gel (LPG), platelet-poor plasma (PPP), and heat inactivated plasma (IP) against methicillin-sensitive Staphylococcus aureus (MSSA) over a period of 24 hours. 2) To determine the degradation of platelet factor-4 (PF-4), transforming growth factor beta 1 (TGF-β1), and platelet-derived growth factor isoform BB (PDGF-BB) in these equine blood components.
