Box rest and analgesia compared to arthroscopic debridement for lame horses with hindlimb subchondral lucencies

In lame horses, caused by osseous cyst-like lesions in the proximal hindlimb, is box rest and analgesia administration more effective at returning the horse to previous level of performance in comparison to arthroscopic debridement?

Treatment.

Two relevant publications were found, both were retrospective case series.

Weak.

The success rate of horses returning to previous level of competition following arthroscopic debridement varies widely in the literature available, from 25-86%. While a study reports 64% return to soundness following rest, it is not clear which horses received strict box rest or paddock rest, the duration of the rest period, and whether non-steroidal anti-inflammatory drugs were also prescribed. It is also worth noting that all horses which undergo surgery will also undergo a period of box rest - which makes the two treatment options difficult to compare.

Newer techniques with better success rates are now available and should be considered in lieu of box rest or arthroscopic debridement. Across all treatments available, age remains an important factor with regards to return to soundness, with older horses having a poorer prognosis. Thorough examinations should therefore be performed to rule out concurrent conditions before deciding upon treatment options.
