“…Carpal arthropathies in particular are a common problem in the racehorse, especially in the racing quarter horse. 3 The most commonly accepted treatment for osteochondral chip fractures involving the carpal bones is arthroscopic removal of the chips followed by a period of rest. Immediate surgical treatment may not be feasible in some horses because of its economic value or racing schedules.…”

Effect of Betamethasone and Exercise on Equine Carpal Joints With Osteochondral Fragments

Osteochondral fragments were created arthroscopically on the distal aspect of both radial carpal bones in 12 horses. On day 14 after surgery, one middle carpal joint of each horse was injected with 2.5 mL Betavet Soluspan (3.9 mg betamethasone sodium phosphate and 12 mg betamethasone acetate per milliliter) and the contralateral joint was injected with 2.5 mL saline as a control. Intra-articular treatments were repeated on day 35. On day 17, six horses began exercising 5 days per week on a high-speed treadmill. The other six horses were kept in box stalls throughout the study as nonexercised controls. On day 56, all horses were examined clinically and radiographically and then were euthanatized. Samples were obtained for histological, histochemical, and biochemical evaluation. Mild lameness was observed in five of the six exercised horses at day 56; four horses were lame in the control limb and one horse was lame in the treated limb. Of the five nonexercised horses evaluated for lameness, two were lame in the control limb, two were lame in the treated limb, and one was lame in both the control and the treated limb. No differences were noted on radiographs or palpation of steroid treated limbs versus control limbs. Firm reattachment of the osteochondral fragment to the radial carpal bone occurred in all but three joints. Gross cartilage damage was not different between steroid-treated joints and joints injected with saline. Histologically, there were no significant detrimental effects of beta-methasone with or without exercise, but there was a tendency for more pathological change in treated joints. No significant difference in the water content or uronic acid concentration was detected between treated and control joints. Intra-articular betamethasone administration in this carpal chip model was not associated with any significant detrimental effects in either rested or exercised horses.

“…The exceptions are horses that have progressed to the chronic or 'recurrent' category and have developed a marked periosteal reaction along with chronic inflammation and associated soft tissue swelling. Less commonly, a more focal area of swelling may be present at some point along the dorsal diaphysis, 1 which must be differentiated from a true stress fracture (see section below).…”

“…In contrast, dorsal metacarpal stress fractures in Quarter Horses are seen predominantly in two year olds. 1 In Thoroughbreds, these fractures appear to be more common in males than females, [21][22][23][24][25] but whether this simply reflects a referral bias or a true physiologic difference between males and females remains incompletely understood. 23,38,39 Fractures most commonly involve the left forelimb in Thoroughbreds in the US (72-91%).…”

The placement of the needle was determined by locating the distal end of the lateral supracondylar crest and the most proximal palpable point of the ulna.…”

Summary Elbows from cadaver limbs were evaluated to determine the presence of a communication between the ulnaris lateralis bursa (ULB) and the joint and the extent of the bursa. Thirty‐two pairs of joints were studied: 12 pairs were frozen, then transversely sectioned and 20 pairs were injected with methyl methacrylate. The 12 frozen‐section pairs revealed a communication between the ULB and the elbow joint in 9/24 joints (37.5%) and a true bursa (absence of communication) in 15/24 joints (62.5%). The mean bursal length in adult horses was 3.8 cm. There was no significant difference in the length of the bursa or presence of bursa‐joint communication between the right and left limbs. In the acrylic specimens a communication between the ULB and the joint was found in 19/40 specimens (47.5%). There was no significant correlation between age or sex and frequency of communication. There was a significantly greater prevalence of communications present in Quarter Horse than in non‐Quarter Horse (P < 0.05) joints. A communication between the ULB and the joint is not always present, and therefore injection of the elbow joint via the ULB may be unreliable.
