articular cartilage removal from equine proximal interphalangeal joints using cannulated drill bits.

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.
