摘要

本病例报告详细介绍了一只小型雷克斯兔股骨远端骨骺骨折的表现、治疗和中期随访。一只5个月大的兔子在试图逃跑并被笼子缠住后出现右后肢跛行。检查发现右股骨远端不稳定,x线片显示Salter-Harris I型骨折。在全身麻醉下使用4个0.7 mm的十字针进行切开复位内固定。术后3周临床及影像学进展满意。术后随访6周后,跛行轻度,12周时跛行消退。术后12周的x线片显示,对准、并列和种植体放置保持良好,无种植体相关并发症。临床愈合。术后7个月对主人的远程随访显示,在骨折修复后,兔子恢复了正常的活动水平,没有出现不良后遗症。十字针置入后的中期结果令人满意,表明这可能是兔股骨远端Salter-Harris I型骨折的合适修复方法。据作者所知,这是第一次在这个年龄的兔子中成功进行Salter-Harris I型骨折的交叉针固定。

Cross-pin stabilisation of a distal femoral physeal fracture in a miniature Rex rabbit
This case report details the presentation, treatment and medium-term follow up for a distal femoral physeal fracture in a miniature Rex rabbit. A 5-month-old rabbit presented with right hindlimb lameness after attempting to escape and becoming entangled in a cage. On examination, instability affecting the distal right femur was noted, and radiographs revealed a Salter-Harris type I fracture. Open reduction and internal fixation was performed under general anaesthesia using four 0.7 mm cross pins. Satisfactory clinical and radiographic progress was noted 3 weeks postoperatively. At postoperative follow up 6 weeks later, lameness was mild and by 12 weeks the lameness had resolved. Radiographs taken 12 weeks postoperatively revealed that alignment, apposition and implant placement had been maintained and there was no evidence of implant-associated complications. Clinical union had been achieved. Remote follow up with the owners 7 months postoperatively revealed that the rabbit had returned to normal activity levels and experienced no adverse sequelae following the fracture's repair. The satisfactory medium-term outcomes seen after cross-pin placement indicate that this may be an appropriate repair method for distal femoral Salter-Harris type I fractures in rabbits. To the authors’ knowledge, this is the first succesful cross-pin stabilisation of a Salter-Harris type I fracture in a rabbit of this age.
