SummaryBackgroundThe digital flexor tendon sheath (DFTS) is a common site of pathology in the UK equine population, often necessitating tenoscopic exploration. Common intrathecal pathologies may lead to fetlock canal constriction. The palmar/plantar annular ligament (PAL) is often surgically transected to relieve constriction or to facilitate surgical access and instrumentation.ObjectivesThe objectives of this study were (1) to establish whether diagnostic quality needle tenoscopy can be achieved in the proximal DFTS in cadaver limbs; (2) to determine if needle tenoscopy can be used to safely guide PAL transection; and (3) to evaluate iatrogenic damage when undertaking needle tenoscopy and PAL transection.Study designEx vivo experimental.MethodsSix cadaveric limbs were used and needle tenoscopy of the DFTS was performed via biaxial approach at the base of the sesamoids. Access to and diagnostic assessment of the proximal DFTS, as well as the completeness of needle tenoscopically guided transection of the PAL was recorded. Limbs were dissected and examined for iatrogenic damage and completion of PAL transection.ResultsPositioning of the cannula/obturator unit was achieved on the first attempt 11/12 times. Laterally 16/24 and medially 18/24 proximal DFTS channels were accessed. Images were of diagnostic quality in 12/24 and 11/24 channels following lateral and medial approach, respectively. The PAL was completely transected in 4/6 limbs with partial transection in 1/6 limbs. The superficial digital flexor tendon (SDFT) was . |
