Summary
# Arthroscopic Debridement for Proximal Phalanx Fractures in Racing Thoroughbreds Frontal plane fractures of the proximal phalanx represent a significant injury in flat-racing Thoroughbreds, yet limited evidence exists comparing surgical approaches; Elzer and Bramlage introduced arthroscopic debridement as an alternative to traditional internal fixation or conservative management and assessed its efficacy through a retrospective analysis of 81 treated horses matched against uninjured controls. Using diagnostic imaging and operative records, the authors characterised the lesions and refined their arthroscopic technique, then compared post-operative racing metrics including career length, number of starts, prize money and race quality. Of the 81 treated horses, 74 (91%) returned to racing, though they completed fewer starts post-injury (median 12 versus 19 in controls; P <0.001); remarkably, earnings were equivalent between groups (median $51,465 versus $68,017; P=0.7), and career longevity showed no significant difference (median 7 quarters versus 9; P=0.1). This approach preserves economic and competitive viability despite reducing race frequency, suggesting arthroscopic debridement offers a meaningful alternative for horses with these fractures, particularly where maintaining breeding or competitive value is a priority—though the retrospective design warrants cautious interpretation and prospective validation before establishing it as standard practice.

Practical Takeaways
- •Arthroscopic debridement is a viable treatment option for frontal plane proximal phalanx fractures in racing Thoroughbreds, with 91% returning to competitive racing
- •While treated horses may race fewer times post-injury, their earnings and career length remain comparable to uninjured peers, suggesting economically viable outcomes
- •This technique offers an alternative to nonsurgical management and internal fixation, though prospective comparative studies would strengthen treatment recommendations
Key Findings
- •91% of 81 Thoroughbreds treated with arthroscopic debridement for proximal phalanx fractures returned to racing post-operatively
- •Treated horses had fewer post-operative starts than matched controls (median 12 vs 19; P<0.001)
- •No significant difference in post-operative earnings between treated horses and controls (median $51,465 vs $68,017; P=0.7)
- •Career longevity was similar between treated horses and uninjured controls (median 7 vs 9 quarters; P=0.1)
