Clinical findings and management of six horses with subtendinous bursitis of the long digital extensor tendon in the hind limb fetlock.

Abstract

OBJECTIVE\nTo describe the history, clinical signs, and management of six horses in which subtendinous bursitis of the long digital extensor tendon (LDET) in the hind limb fetlock had been diagnosed.\n\n\nSTUDY DESIGN\nRetrospective case series.\n\n\nSAMPLE POPULATION\nSix privately owned horses.\n\n\nMETHODS\nThe medical records of horses presented at the hospital with similar sypmtoms were evaluated and collected. Finally 6 horses met the inclusion criteria and the relevant data were compiled and analysed. In three of the six cases a surgical treatment was carried out.\n\n\nRESULTS\nAll horses had similar clinical signs, mainly distention beneath the long digital extensor tendon (LDET) at the level of the hind limb fetlock without associated lameness; the major issues were the presence of cosmetic defects and concern about their functional use in the future. Three of the six horses were treated surgically with bursoscopic debridement. The cosmetic results were excellent in two of these three horses. One horse that underwent an operation experienced a recurrence. None of the horses with bursitis treated medically experienced resolution of the problem.\n\n\nCONCLUSION\nBursoscopy is a technique to consider for the management of bursitis of the LDET at the level of the fetlock combined with prolonged bandage application when medical treatment has failed to manage the condition.\n\n\nCLINICAL SIGNIFICANCE\nTo the best of our knowledge, subtendinous bursitis of the LDET in the hind limb is not a commonly diagnosed condition. This small case series provides some insight into methods for the clinical management of this issue.
