Four horses were included, each presenting with acute hindlimb lameness following fast exercise. The cases involved a 4-year-old Standardbred mare used for racing, a 5-year-old Thoroughbred mare used for jump racing, a 7-year-old Thoroughbred gelding also used for jump racing and a 6-year-old French Trotter mare. Clinical features included marked lameness, mild swelling and pain on palpation of the proximal metatarsal region. The fracture location and configuration were consistently identified by D40-50°M-PlLO radiographical projections. All cases were repaired using screws placed in lag fashion but one case subsequently required double plate fixation due to fracture propagation. Three horses returned to their previous level of exercise between 7 and 8 months and successfully raced between 9- and 14-month postoperatively with two horses subsequently winning. One horse was retired to stud as a broodmare. It was concluded that accurate diagnosis and surgical repair of this fracture type can result in a good outcome and return to athletic function in affected racehorses.</p>","PeriodicalId":11786,"journal":{"name":"Equine Veterinary Education","volume":"38 10","pages":"e721-e728"},"PeriodicalIF":1.1,"publicationDate":"2026-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/eve.70117","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148871879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The horse presented with right front fetlock varus, physeal closure of distal third metacarpus (MCIII), AAEP grade 4/5 lameness, and subluxation with degenerative joint disease of the metacarpophalangeal joint. A prior attempt for growth retardation using a transphyseal screw did not result in correction. A radial osteotomy was performed proximal to the distal physis of MCIII using a crescentic saw blade. Axial alignment was achieved by rotating the distal fragment of MCIII laterally in the frontal plane and fixated with two narrow 4.5 mm LCPs. Complications after surgery included surgical site infection, incisional dehiscence and progressive degenerative joint disease. Twenty weeks post-surgery the surgical site was completely healed, and the horse was sound at the walk. Radiographs showed correction of the varus deformity from 15° to 2°.

However, nowhere in the literature is it specified how these two structures differ histologically, leading to a diagnostic conundrum for pathologists and surgeons alike. This article reviews the relevant literature in both equine and human medicine, on which the equine world's understanding of ECs is based, finds the two histologically indistinguishable and suggests these terms are in fact not differentials, but rather that a spherical keratoma may be a type of EC, and that histological evidence from the scarcely documented subungual epidermoid inclusion cyst in humans could provide insight into the pathogenesis of spherical keratoma formation in horses.
