The medical records of 9 foals less than 4 months old, with fracture of the tibial diaphysis, were reviewed. Open reduction was accomplished by use of 3 approaches; however, a cranial approach was preferred and was used in 7 foals. Two dynamic compression plates were implanted in all foals except the first of this series. The technique of plate luting was used in 7 foals and appeared to improve the ability of implants to resist failure. Complications after surgery included partial or complete failure of fracture fixation (n = 3 foals), osteomyelitis (n = 2 foals), angular limb deformity (n = 2 foals), minor dehiscence of the surgical wound (n = 3 foals), and mild extensor deficits of the injured limb (n = 4 foals). One foal was euthanatized 12 hours after surgery because of complete loss of fracture fixation. All other foals were discharged 10 to 295 days after surgery. One or both plates were subsequently removed in 7 foals. Follow-up information was obtained 6 to 36 months after discharge. Excellent results were reported for 6 foals, and good or fair results were reported for the remaining 2 foals.
