Haematogenous synovial sepsis of the digital flexor tendon sheath following contralateral limb foot abscessation in a horse

Abstract

AbstractA 5‐year‐old Shire mare was presented for investigation of severe right hindlimb lameness and was diagnosed with extensive right hind subsolar and submural foot abscessation. The mare developed severe contralateral limb lameness 11 days following right hind abscess debridement, with investigation revealing synovial sepsis of the left hind digital flexor tendon sheath. Synovial sepsis persisted despite aggressive surgical and medical treatment, resulting in euthanasia. Microbial culture of synovial fluid isolated Bacteroides sp., consistent with haematogenous synovial sepsis. This is the first report to describe haematogenous synovial sepsis as a cause of contralateral limb lameness during the management of foot abscessation in the horse.
