Abstract
Letsels ter hoogte van structuren in de sesamschede kunnen de primaire oorzaak zijn van nietinfectieuze tenosynovitis, waarbij tenoscopie zowel diagnostisch als therapeutisch aangewend kan worden. In deze studie werden de gegevens van vijftig paarden uit de databank van de Faculteit Diergeneeskunde (UGent) verzameld, die in de periode van 2008 tot 2016 een tenoscopische behandeling van niet-infectieuze tenosynovitis van de sesamschede ondergingen. Telefonische follow-up informatie kon van veertig paarden worden bekomen. Bij springpaarden waren de voorbenen significant vaker aangetast dan de achterbenen, terwijl letsels bij paarden die niet voor jumping gebruikt werden, frequenter ter hoogte van de achterbenen werden vastgesteld (P=0,01). Letsels van de diepe buigpees vertegenwoordigden 45% van de gevallen terwijl er in 39% van de gevallen letsels ter hoogte van de manica flexoria waren. Uiteindelijk konden 27,7% van de paarden met laesies van de diepe buigpees en 53% paarden met laesies van de manica flexoria terug op hun oorspronkelijk niveau worden ingezet met een gemiddelde follow-upperiode van 4,6 ± 2,5 jaar.
Highlights
The digital flexor tendon sheath (DFTS) is a synovial structure at the palmar/ plantar aspect of the fetlock region, surrounding the superficial digital flexor tendon (SDFT) and the deep digital flexor tendon (DDFT) (Stanek, 2006; König and Liebich, 2008)
The left limb was even treated a second time six years later, revealing an additional DDFT lesion that was not detected during the initial surgery
In one of the three horses with bilateral lesions, tenoscopy was performed in both hind limbs at the same time
Summary
The digital flexor tendon sheath (DFTS) is a synovial structure at the palmar/ plantar aspect of the fetlock region, surrounding the superficial digital flexor tendon (SDFT) and the deep digital flexor tendon (DDFT) (Stanek, 2006; König and Liebich, 2008). Three annular ligaments are incorporated into the palmar/ plantar wall of the DFTS (Stanek, 2006; König and Liebich, 2008; Schramme and Smith, 2010). Anulare palmare/plantare) (PAL) surrounds the flexor tendons at the level of the fetlock/ proximal sesamoid bones and may appear as a constrictive band when distension of the DFTS is present. This distension is commonly caused by a lesion within the DFTS. The distal digital annular ligament (lig. anulare digitale distale) is located more distally in the pastern and adheres to the terminal portion of the DDFT (König and Liebich, 2008; Schramme and Smith, 2010)
