A 6-month-old heifer had a valgus deformity of the metatarsophalangeal region secondary to a malunion of a Salter-Harris type II fracture. The degree of deformity angulation ranged from 16\u00b0 to 54\u00b0 for the 4 patients.<\/jats:p>\n<\/jats:sec>\n\nTREATMENT AND OUTCOME<\/jats:title>\nA closing wedge ostectomy with transfixation pin\u2013cast application was performed on the affected limb of all 4 patients. The ostectomy healed with only minor complications (disuse osteopenia distal to the transfixation pins [n = 4] and cast sores [1]) that were easily resolved with no long-term adverse effects. Duration of follow-up for the 4 patients ranged from 6 to 17 months, and the owners reported satisfactory ambulation with no (n = 2) or only mild (2) residual lameness in the affected limb.<\/jats:p>\n<\/jats:sec>\n\nCLINICAL RELEVANCE<\/jats:title>\nResults suggested that a closing wedge ostectomy with transfixation pin\u2013cast stabilization is an alternative for management of angular limb deformities of the metatarsophalangeal region in cattle. Such treatment improved the quality of life for all 4 patients. However, 2 of the 4 patients had congenital deformities confirmed to be heritable. There are ethical concerns associated with treating animals with heritable disorders, and exhibition and breeding of such animals should be avoided.<\/jats:p>\n<\/jats:sec>","DOI":"10.2460\/javma.255.9.1047","type":"journal-article","created":{"date-parts":[[2019,10,16]],"date-time":"2019-10-16T14:55:38Z","timestamp":1571237738000},"page":"1047-1056","source":"Crossref","is-referenced-by-count":3,"title":["Closing wedge ostectomy with transfixation pin\u2013cast stabilization for correction of angular limb deformities of the metatarsophalangeal region in four cattle"],"prefix":"10.2460","volume":"255","author":[{"given":"Joseph W.","family":"Lozier","sequence":"first","affiliation":[{"name":"1Hospital for Farm Animals, Department of Veterinary Clinical Sciences, College of Veterinary Medicine, The Ohio State University, Columbus, OH 43210."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew J.","family":"Niehaus","sequence":"additional","affiliation":[{"name":"1Hospital for Farm Animals, Department of Veterinary Clinical Sciences, College of Veterinary Medicine, The Ohio State University, Columbus, OH 43210."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.
