OBJECTIVE
This report evaluates the use of 4.5- and 5.5-mm cannulated drill bits for articular cartilage removal from the proximal interphalangeal joints of equine cadaver limbs.
ANIMALS
Limbs from 8 equine cadavers, all with normal proximal interphalangeal joints.
PROCEDURE
Proximal interphalangeal joints of 32 limbs from 8 equine cadavers were drilled using either 4.5- or 5.5-mm cannulated drill bits. Pastern joints were then disarticulated, and intra-articular drilling was evaluated by visual inspection.
RESULTS
Post-drilling evaluation revealed complete intra-articular drilling occurred in all 32 joints.
CONCLUSION
Canulated 4.5- and 5.5-mm drill bits resulted in consistent accurate intra-articular drilling in the proximal interphalangeal joint of horses.
CLINICAL RELEVANCE
Cannulated drill bits provided an effective and consistent modality for articular cartilage removal with potential for improved accuracy of articular drilling and applications in minimally invasive proximal interphalangeal joint arthrodesis.
目的
本报告评估了在马尸体肢的近侧指间关节中使用 4.5 和 5.5 毫米空心钻头去除关节软骨的效果。
动物
8 具马尸体的肢体，所有都具有正常的近侧指间关节。
手术过程
使用 4.5 或 5.5 毫米空心钻头对 8 具马尸体的 32 个肢体的近侧指间关节进行钻孔。然后离断跗关节，并通过肉眼观察评估关节内钻孔情况。
结果
钻孔后评估显示，所有 32 个关节均完全进行了关节内钻孔。
结论
空心 4.5 和 5.5 毫米钻头可在马的近侧指间关节中实现一致、准确的关节内钻孔。
临床相关性
空心钻头提供了一种有效的、一致的关节软骨去除方法，具有提高关节钻孔准确性的潜力，可应用于微创近侧指间关节融合术。
