Fracture of the digits is a well-known orthopedic condition in adult cattle, and mainly the distal phalanx (P3) is involved. To our knowledge, the treatment of fractures of the middle (P2) and proximal (P1) phalanges with orthopedic claw blocks has not yet been described in cattle and other ruminants. This report describes the first case of the successful management of a P1 fracture in an adult European bison. A 5-year-old female European bison () presented with severe weight bearing lameness of the left hind limb and a marked soft tissue swelling accentuated over the plantar and lateral aspects of the proximal and middle phalanges, associated with multifocal light bluish discoloration of the skin (hematoma) and increased local temperature. The cow was examined and managed because of a severely comminuted fracture of the lateral P1 of the left hind limb. Application of an orthopedic block on the healthy medial partner claw allowed to reduce the load of the affected digit. Combined with the administration of non-steroidal anti-inflammatory drugs, it supported immobilization and recovery. Radiographic re-evaluations at weeks 6, 9, and 11 after the injury revealed progressive callus formation and fracture consolidation. From week 9 onwards, until the end of treatment, no lameness was observed. The healing process was good, and both clinical and radiographical improvement were evident after immobilizing the affected digit by applying an orthopedic claw block on the healthy partner claw and administering non-steroidal anti-inflammatory drugs.
指骨骨折是成年牛中一种常见的骨科病症，主要累及远端指骨（P3）。据我们所知，在牛和其他反刍动物中，尚未有使用矫形爪形阻滞治疗中指（P2）和近端指骨（P1）骨折的相关描述。本报告描述了首例成功治疗成年欧洲野牛P1骨折的病例。一头5岁雌性欧洲野牛（）出现左后肢严重负重跛行，近端和中指骨的跖侧和外侧软组织明显肿胀，并伴有皮肤多处浅蓝色变色（血肿）和局部温度升高。该母牛因左后肢外侧P1严重粉碎性骨折接受检查和治疗。在健康的内侧副爪上应用矫形阻滞可减轻患指的负荷。结合使用非甾体类抗炎药，有助于固定和恢复。受伤后第6、9和11周的影像学复查显示骨痂逐渐形成，骨折愈合。从第9周起直至治疗结束，未观察到跛行。通过在健康的副爪上应用矫形爪形阻滞固定患指并给予非甾体类抗炎药后，愈合过程良好，临床和影像学均有明显改善。
