Radiography and computed tomography revealed severe atrophy of the proximal bone fragment and retardation of the ipsilateral distal fragment and tibia. An autogenous bone graft using coccygeal bone was performed, in which three and a half coccyges were placed in succession and fixed using an orthogonal locking plate. To promote bone healing and facilitate proper weight bearing and ambulation, bone morphogenetic proteins, biphasic calcium phosphate, platelet-rich plasma, passive-range-of-motion exercises, transcutaneous electrical nerve stimulation, neuromuscular electrical stimulation, and low-level laser therapy were applied. During the four-year follow-up, it was observed that the previously engrafted bone healed well and maintained stability over a prolonged period, resulting in the patient being able to walk comfortably with good outcomes. However, some degree of lameness was noted in the dog when running owing to limb shortening and joint contracture.<\/jats:p>","DOI":"10.3390\/vetsci10060388","type":"journal-article","created":{"date-parts":[[2023,6,7]],"date-time":"2023-06-07T02:02:15Z","timestamp":1686103335000},"page":"388","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Treatment of a Large Defect Induced by Atrophic Nonunion of Femoral Fracture in a Dog with Autogenous Coccygeal Bone Grafting"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-2998-2343","authenticated-orcid":false,"given":"Kyuman","family":"Cho","sequence":"first","affiliation":[{"name":"Chokyuman Vet Surgical Center, Bucheon 14624, Republic of Korea"},{"name":"Veterinary Medical Research Institute, Jeju National University, Jeju 63243, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-7190-5280","authenticated-orcid":false,"given":"Kilsang","family":"Lee","sequence":"additional","affiliation":[{"name":"Chokyuman Vet Surgical Center, Bucheon 14624, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-0258-2729","authenticated-orcid":false,"given":"Kyungsik","family":"Kang","sequence":"additional","affiliation":[{"name":"Chokyuman Vet Surgical Center, Bucheon 14624, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2135-4305","authenticated-orcid":false,"given":"Minkyung","family":"Kim","sequence":"additional","affiliation":[{"name":"Keunmaum Animal Medical Center, Busan 48096, Republic of Korea"},{"name":"Department of Veterinary Surgery, College of Veterinary Medicine, Gyeongsang National University, Jinju 52828, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3223","DOI":"10.5433\/1679-0359.2016v37n5p3223","article-title":"Nonunion fractures in small animals\u2014A literature review","volume":"37","author":"Ferrigno","year":"2016","journal-title":"Semin.
