To determine outcome after repair of long bone fractures in llamas and alpacas.
Case series.
Llamas (n=11) and alpacas (8).
Medical records (1998-2008) of camelids with long bone fractures were reviewed for history, repair method, and complications. Outcome was also assessed by owner telephone questionnaire.
Mean age at repair was 39 months. There were 8 males and 11 females. Fracture distribution was tibia (n=6), metatarsus (5), metacarpus (4), radius and ulna (2), humerus (1), and femur (1), with 13 closed and 6 open fractures. Fracture repair was by internal fixation (n=11), external fixation with a transfixation pin cast (5), external coaptation (2), and cross-pinning (1). In 1 llama, the limb was amputated to revise a failed external fixation repair. Seventeen animals (89%) were discharged, and 2 were euthanatized. Outcome was available for 13 animals: 9 were used for breeding and 4 as pets. Fewer major complications occurred with internal fixation than with external fixation with a transfixation pin cast (P<.005); however, there were no significant differences in minor complications between groups.
Internal fixation with bone plates was associated with fewer major complications than external fixation with a transfixation pin cast.
确定美洲驼和羊驼长骨骨折修复后的结果。
病例系列。
美洲驼（n = 11）和羊驼（8只）。
回顾1998年至2008年骆驼科动物长骨骨折的病历，了解病史、修复方法和并发症情况。还通过主人电话问卷调查评估结果。
修复时的平均年龄为39个月。有8只雄性和11只雌性。骨折分布为胫骨（n = 6）、跖骨（5）、掌骨（4）、桡骨和尺骨（2）、肱骨（1）和股骨（1），其中13处为闭合性骨折，6处为开放性骨折。骨折修复方法包括内固定（n = 11）、带贯穿针石膏的外固定（5）、外固定包扎（2）和交叉穿针固定（1）。在1只美洲驼中，对失败的外固定修复进行了截肢。17只动物（89%）出院，2只实施了安乐死。有13只动物的结果可供参考：9只用于繁殖，4只作为宠物。内固定的主要并发症比带贯穿针石膏的外固定少（P <.005）；然而，两组之间的 minor 并发症无显著差异。
与带贯穿针石膏的外固定相比，接骨板内固定的主要并发症更少。
