Standing placement of transphyseal screw in the distal radius in 8 Thoroughbred yearlings.

Abstract: This retrospective study describes placement of distal radial transphyseal screws in Thoroughbred yearlings with carpal varus deformities while standing, and identifes short- and long-term complications following the procedure. Data gathered from 2009 to 2013 identified 8 yearlings that met the inclusion criteria. Horses were sedated intravenously and a single 4.5-mm cortical screw was placed in the distal lateral radial physis following application of local anesthetic and surgical preparation of a pre-placed hole. All horses were evaluated weekly after surgery and screw removal was performed standing and under sedation when correction of the angular limb deformity was achieved. The mean time for screw removal was 46 days. No short- or long-term complications were identified. Findings indicate that placing a single transphyseal screw in the lateral aspect of the distal radial physis with the horse standing is a viable option to treat varus angular limb deformity of the carpus in horses. Cette étude rétrospective décrit le placement d’une vis transphysaire dans le radius distal de chevaux Thoroughbred âgés d’un an ayant des difformités du varus carpien, lorsqu’ils sont debout, et elle identifie les complications à court et à long terme après l’intervention. Les données recueillies de 2009 à 2013 ont identifié 8 chevaux âgés d’un an qui satisfaisaient aux critères d’inclusion. Les chevaux ont été mis sous sédation par intraveineuse et une seule vis corticale de 4,5 mm a été placée dans le cartilage diaphyso-éphysaire après l’application d’anesthésie locale et de la préparation chirurgicale d’un trou pratiqué au préalable. Tous les chevaux ont été évalués une fois par semaine après la chirurgie et l’enlèvement de la vis a été réalisé debout et sous sédation lorsque la correction de la difformité angulaire du membre a été obtenue. Le temps moyen de l’enlèvement des vis était de 46 jours. Aucune complication à court ou à long terme n’a été identifiée. Les résultats indiquent que le placement d’une seule vis transphysaire dans l’aspect latéral du cartilage diaphyso-éphysaire distal radial, lorsque le cheval se tient debout, est une option viable pour traiter la difformité angulaire de type varus du carpe chez les chevaux.(Traduit par Isabelle Vallières).

The research outlines a study of performing surgery on Thoroughbred yearlings with a hand deformity, by placing a singular transphyseal screw in the distal radial physis with the horse standing, and evaluating the short-term and long-term complications.

Objective and Methodology

  • The primary objective of the retrospective study was to evaluate the effectiveness and potential complications of placing a singular transphyseal screw in the distal radial physis with the yearling Thoroughbred in a standing position. This procedure was designed to treat carpal varus deformities, a limb deformity.
  • The study examined data collected between 2009 and 2013. The subjects were Thoroughbred yearlings who met certain criteria. A total of eight yearlings were selected for the study.
  • The chosen surgical method involved administering an intravenous sedative, followed by local anesthetic, to the subject. The team then prepared a spot to place a 4.5-mm cortical screw into the horse’s distal lateral radial physis.

Evaluation and Findings

  • Post-surgery, subjects were evaluated on a weekly basis. The transphyseal screw was removed when it was determined that the angular limb deformity had been corrected.
  • On average, the time period for screw removal was found to be 46 days after the surgical procedure.
  • Impressively, no short-term or long-term complications were identified following the surgical procedure and the recovery period, indicating a safe and viable solution for treating carpal varus deformities in Thoroughbred yearlings.
