Relationships between carpal morphology and carpal pathology might assist in identifying horses at risk of carpal pathology. This study was aimed to investigate the hypothesis that carpal morphology is related to the incidence of carpal pathology in racing Thoroughbreds. Ten carpal parameters were used to measure carpal morphology on dorsopalmar (DP) carpal radiographs. Radiographs were collected from 19 experienced Thoroughbred race horses with no evidence of carpal damage(normal)and 72 horses with carpal damage (clinical). All radiographs were at a defined position called zero degrees (ZDP) or within an acceptable rotational range. Based on a P-value of < 0.05 and using the false discovery rate method to control Type I error, two parameters showed significant differences between normal and clinical horses. The angulation of the radial metaphysis and distal radius in relation to the angulation of the radial facet of the third carpal bone (C3) was significantly related to the occurrence of pathology in the bones of the middle carpal joint in Thoroughbred race horses. This study presented important features on DP radiographs that allowed identification of a carpal conformation associated with carpal damage in Thoroughbred race horses. Using such a highly specific, cost-effective and safe technique as a routine for examining yearling Thoroughbreds would assist in identifying horses with carpal conformation unsuited to racing.

Poor performance in athletic horses due to musculoskeletal affections is very common in Libya. Two mature thoroughbred horses suffering from poor performance and history of moderate degree forelimb lameness were admitted to the Aswany Private Equine clinic in Tripoli, Libya. The study is aiming for presenting a simple, time effective, cost effective surgical procedure to treat distal simple splint bone fracture in thoroughbred horses. Horses were examined thoroughly for the common muscle, hoof, and tendons affections. A progressed unilateral left forelimb swelling involving the lateral distal part of the fourth metacarpal bones was noticed. Three radiographs were taken to each horse including latero- medial, dorsolateral-palmaromedial, and palmarolateral-dorsomedial views to assess both splint bones. The radiographs showed that there is a complete fracture involving the distal extremity (button) of the fourth metacarpal bones. Surgical excisions of the fractured part of the splint bones have been decided to treat these horses. To precisely locate the site of the bone fragments, 1.5 mm stainless steel wires were placed over the distal part of splint prior to taking the radiographs. The surgical sites were aseptically prepared, and the horses were then sedated via intravenous injection of xylazine at a dose rate of 1 mg/kg body weight. The site of surgical incision was infiltrated with 2% lidocaine. The bone fragments were then removed after performing the surgical incision. The sharp end at the distal end of the proximal part of the splint bone was then smoothening with a scissor. The surgical incisions were then routinely closed and the post-operative care and radiographs were taken. The surgical incision made complete healing within two weeks. Both horses were followed up for up to three years post-operation, and they did well compared to what has been done in other studies. We concluded that the surgical technique used to treat the two horses with splint bone fracture enrolled in the current study is a simple and effective procedure. arabic 19 English 106

Objective To (1) evaluate thoracic limb loads and symmetry, and elbow function and morphology, before and after arthroscopic treatment of unilateral medial coronoid process disease (MCPD), and (2) determine if functional variables correlate with morphologic findings.Study DesignProspective case series.AnimalsDogs (n = 14) with thoracic limb lameness.Methods Dogs were included when unilateral MCPD was confirmed as the cause of lameness. Kinetic analysis of both thoracic limbs, along with kinematic analysis and goniometry of both elbows were carried out before, and 60, 120, and 180 days after partial coronoidectomy by arthroscopy. Radiography and computed tomography of both elbows were performed before and 180 days after arthroscopy.ResultsA nonsignificant (P = .11) increase in the peak vertical loads (PFz), and a significant (P = .022) increase in the vertical impulse (iFz) applied by the affected limb were seen. Symmetry indices improved, with significant differences between sessions (PFz: P = .019; iFz: P = .003). Kinematic variables showed no significant differences, between sessions or when comparing both elbows within sessions. Goniometry revealed no significant differences between sessions, but some significant differences were identified when comparing both elbows within sessions. Osteophytosis and degree of lameness showed no correlation, before (rs = −0.077; P = .79) or after arthroscopy (rs = 0.27; P = .35).Conclusions Kinetic variables improved after arthroscopy, without full restoration of function. Kinematic variables did not change significantly. Osteoarthritis and goniometric measurements in the affected joint worsened. Functional variables did not correlate with morphologic findings. arabic 23 English 137
