 Background: Despite the fact that slab fracture of the third carpal bone is an event of great worldwide relevance in racehorses, the third carpal fracture doesn’t have data on treatments and return to racing in Brazil. The search for efficient treatments and which provide recovery providing horses return to racing is an objective of sports equine medicine. Regenerative therapies like Platelet Rich Plasma (PRP) and Stem Cells (MSc) have demonstrated a great potential in the treatment of several injuries. For the treatment of three Thoroughbred racing horses at Brazilian Jockey Club, with sagittal plane slab fractures of the third carpal bone, we used the association of PRP and Stem Cells for reduction of the rest and good return to conditions athletics of these horses.Cases: Three Thoroughbred racing horses, males, 4 and 5 years old, showed slab fracture third carpal bone in different moments of their activity at Brazilian Jockey Club. Usually, the treatment for this type of fracture is the arthroscopic repair and the conservative management. We performed after initial radiographic evaluation dorsoproximal-dorsodistal oblique (DPr-DDiO) “skyline”, intra-articular applications of PRP and MSCs. The treatments were performed according to the radiographic follow-up of the lesion evolution. No other treatment was performed concomitantly with cell therapy in the 3 treated patients. Three treatments were performed in the first patient and 2 in the second and third patients. Before each treatment for all patients, we performed radiography dorsoproximal-dorsodistal oblique (DPr-DDiO) ‘skyline’ of the carpus. After this step, the animal was sedated with 10% xylazine hydrochloride at a dose of 0.5 mg/kg intravenously. Antisepsis of the carpus was performed and applied with radiographic monitoring of the needle positioning, first the PRP in the volume of 2 mL and in sequence, 20 million cells MSCs suspended in autologous plasma from the cell bank of the Cellen veterinary stem cell laboratory, totalizing 4 mL. The 3 horses returned to their training routines and continued to be monitored by clinical examinations and radiography, there were no post-treatment complications and all ran again in the median time of 253 days after the first application of PRP and stem cells. Everyone won the first race after treatment.Discussion: The 3 patients suffered the fractures after running at the Brazilian Jockey Club. All fractures were simple- no comminuted slab fractures of the third carpal. In our study, we chose to carry out the treatments with PRP and MSCs by intra-articular application. The regenerative medicine occupies a prominent place in recovery from injuries and the association of PRP and MSCs have played an important role in the treatment of athlete horses in tendons, bones and joint injuries and our work, the treatment was effective, without complications, helped to reduce local inflammation, perceptually reducing the pain observed before the application and the animals started running again with a quality equivalent to that observed before the occurrence of injuries. This way, our results demonstrated that the association PRP and MSCs was effective in recovering the 3 patients, all of them ran after injury. The median time for racing was 253 days and the horses won their first races after fractures occurred. These results encourage the use of the association of PRP and MSCs also for no comminuted sagittal plane slab fractures of the third carpal in Thoroughbred Racing horses.

Secondary Fractures

SummaryImplant associated fractures have not been reported in horses. Two horses were evaluated for fractures in the fore limbs, occurring subsequent to previous fracture repair. Previously, the horses had sustained fractures of unusual configurations which were repaired using internal fixation. Following repair and healing of the fractures, secondary fractures occurred in the same bone, but in a different (more common) configuration. The first horse was evaluated ten months following lag screw fixation of a longitudinal fracture of the proximal phalanx in a frontal plane. This horse presented with a more typical comminuted fracture in the sagittal plane with the screws from the first fixation lying in the fracture line. This fracture was successfully treated with a cast. The second horse was examined eightteen months after repair of a medial sagittal slab fracture of the third carpal bone. The horse presented with a more typical dorsal slab fracture of the third carpal bone with the previously placed lag screw lying in the fracture line. The screw was removed and a lag screw was placed perpendicular to the new fracture plane through the dorsal surface of the third carpal bone to repair the fracture.

SummaryFifty-two carpal panarthrodeses (CP) were carried out in 44 dogs (eight bilateral), in a multicentre study using a single (n = 47) or double (n = 5) stepped hybrid CP plate. Of these 44 cases, 39 were between 20–55 kg in bodyweight , 26 were males , and the carpometacarpal was the most common joint involved. Falling and other impact trauma were the most common aetiology. Pain of unknown origin, carpal luxation, chronic accessory carpal bone fracture, distal comminuted intra-articular radial fracture, bone tumour, degenerative joint disease, canine erosive idiopathic polyarthritis, avascular necrosis of the radial carpal bone and fractures of several metacarpal bones were some of the pathologies reported. Fracture of the third metacarpal bone during screw insertion was the only intrasurgical complication. Malpositioning of the plate or screws and over-tightened screws were technical errors observed in seven of the procedures. The radial carpal bone was not fixed with a screw in two cases due to bone deformity. Concurrent plate breakage and bending in the same patient operated on bilaterally was observed during the follow-up period, which represented a major complication rate of 3.8% for all procedures. Minor complications were: low grade infection, lick granuloma, digit hyperextension, screw loosening or failure, incomplete fusion of some joints and a fracture of the third metacarpal bone at the distal screw hole of the plate; which represented a rate of 44.2% on all procedures. Complete carpal healing was observed radiographically in 94.2% of all procedures. Limb function was excellent to good, and all of the owners, except for one, were satisfied with the procedure.
