Plain-English summary

In this study, 17 young horses (foals) with problems in their leg bones, specifically at the ends of the radius, tibia, and metacarpal/metatarsal bones, underwent a specific surgical procedure to help straighten their legs. The surgery involved cutting a part of the tissue around the bone near the growth plate on the side where the bone was bending inward. After the surgery, all the foals showed some improvement, with the best results seen in the radius, where 22 out of 25 limbs were corrected to a slight deviation of 4 degrees or less. The surgery also provided satisfactory results for the tibias and the other bones involved. Overall, the treatment was effective in correcting the angular limb deformities.

Abstract

Seventeen foals with angular limb deformities of the distal end of the radius (valgus: 26 limbs), distal end of the tibia (valgus: 6 limbs), and distal end of the 3rd metacarpal bone/metatarsal bone (varus: 4 limbs) were treated surgically by means of hemicircumferential division of the periosteum proximal to the involved growth plate, at the concave side of the bone. There was some correction in all cases. The best results were seen in the radius, where 22 of 25 limbs were corrected to a deviation of 4 degrees or less. Satisfactory correction was obtained in the 6 tibias, the 2 third metacarpal bones, and the 2 metatarsal bones.
