Vet. Sci."],"abstract":"<jats:p>A domestic shorthair cat, estimated 1 year old, was presented from a local rescue with traumatic injuries of unknown cause to both pelvic limbs. Radiographs revealed a left tibial malunion with marked callus formation and complex right tarsocrural joint injuries. A modified chipping technique was used to provide a source of autogenous bone graft from the callus for both the malunion correction and the contralateral pantarsal arthrodesis. Post-operative radiographs showed significant improvement in the left tibial alignment and adequate arthrodesis of the right tarsal joints. There was good functional outcome at 3 months post-operatively. This case report highlights the potential of bone callus to be used as a bone graft, presenting a unique technique to avoid donor site morbidity associated with traditional autogenous bone grafts. The modified chipping technique can also be employed in malunion revision surgeries to effectively correct resultant angular deformities while preserving the fracture haematoma. To the authors' knowledge these have not been reported in the veterinary literature.<\/jats:p>","DOI":"10.3389\/fvets.2025.1665297","type":"journal-article","created":{"date-parts":[[2026,1,2]],"date-time":"2026-01-02T05:24:30Z","timestamp":1767331470000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Use of bone callus as a source of bone graft for concurrent tibial malunion repair and contralateral pantarsal arthrodesis in a domestic shorthair cat\u2014a case report"],"prefix":"10.3389","volume":"12","author":[{"given":"Gracia","family":"Tian","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jayson","family":"Tuan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2026,1,2]]},"reference":[{"key":"B1","first-page":"1176","article-title":"Fractures of the tibia and fibula","volume-title":"Veterinary Surgery: Small Animal.","author":"Hayashi","year":"2018"},{"key":"B2","first-page":"172","article-title":"Delayed unions, nonunions, and malunions","volume-title":"Veterinary Surgery: Small Animal","author":"Kraus","year":"2018"},{"key":"B3","doi-asserted-by":"publisher","first-page":"S47","DOI":"10.1016\/S0020-1383(16)30839-7","article-title":"Femoral non-union with malalignment: reconstruction and biological stimulation with the chipping technique","volume":"47","author":"Watanabe","year":"2016","journal-title":"Injury."},{"key":"B4","doi-asserted-by":"publisher","first-page":"000628","DOI":"10.26717\/BJSTR.2017.01.000628","article-title":"Tibia malunion with angular deformity: corrective osteotomy and intramedullary fixation with the chipping technique","volume":"2","author":"Yusof","year":"2018","journal-title":"Biomed J Sci Tech Res."},{"key":"B5","first-page":"1193","article-title":"Tarsus and metatarsus","volume-title":"Veterinary Surgery: Small Animal","author":"Carmichael","year":"2018"},{"key":"B6","doi-asserted-by":"publisher","first-page":"134","DOI":"10.1016\/j.jss.2018.03.022","article-title":"Prolonged operative duration is associated with complications: a systematic review and meta-analysis","volume":"229","author":"Cheng","year":"2018","journal-title":"J Surg Res."},{"key":"B7","doi-asserted-by":"publisher","first-page":"36330","DOI":"10.1038\/srep36330","article-title":"The osteogenic potential of human bone callus","volume":"6","author":"Han","year":"2016","journal-title":"Sci Rep."},{"key":"B8","doi-asserted-by":"publisher","first-page":"3554","DOI":"10.3390\/jcm10163554","article-title":"Insights into the cellular and molecular mechanisms that govern the fracture healing process: a narrative review","volume":"10","author":"Papachristou","year":"2021","journal-title":"J Clin Med."},{"key":"B9","doi-asserted-by":"publisher","first-page":"476","DOI":"10.1177\/1098612X19854809","article-title":"Radiographic study of development of pelvis and hip and femorotibial joints in domestic cats","volume":"22","author":"Miranda","year":"2020","journal-title":"J Feline Med Surg."},{"key":"B10","doi-asserted-by":"publisher","first-page":"399","DOI":"10.3415\/VCOT-12-05-0063","article-title":"Feline pantarsal arthrodesis using pre-contoured dorsal plates applied according to the principles of percutaneous plate arthrodesis","volume":"26","author":"Fitzpatrick","year":"2013","journal-title":"Vet Comp Orthop Traumatol."},{"key":"B11","doi-asserted-by":"publisher","first-page":"734","DOI":"10.1136\/vr.c5893","article-title":"Owners' observations of domestic cats after limb amputation","volume":"167","author":"Forster","year":"2010","journal-title":"Vet Rec."},{"key":"B12","doi-asserted-by":"publisher","first-page":"662","DOI":"10.1177\/1098612X221106354","article-title":"Feline diaphyseal fractures: management and treatment options","volume":"24","author":"Zurita","year":"2022","journal-title":"J Feline Med Surg."},{"key":"B13","doi-asserted-by":"publisher","first-page":"109","DOI":"10.3415\/VCOT-14-08-0120","article-title":"Impact of fixation method on postoperative complication rates following surgical stabilization of diaphyseal tibial fractures in cats","volume":"28","author":"Perry","year":"2015","journal-title":"Vet Comp Orthop Traumatol."},{"key":"B14","first-page":"199","article-title":"Stimulating bone growth in the small animal patient: grafts and beyond!
