Comparison of Two Surgical Techniques for the Treatment of Equine Hindlimb Proximal Suspensory Desmopathy

Abstract

The objective of this retrospective study was to compare outcomes after desmoplasty with fasciotomy (DF) against deep branch of the lateral plantar neurectomy with fasciotomy (NF) for lameness due to proximal suspensory desmopathy in the hindlimb. Medical records from 141 horses with proximal suspensory desmopathy treated by either desmoplasty with fasciotomy or deep branch of the lateral plantar neurectomy with fasciotomy were reviewed. Follow-up after surgery to determine resolution of the lameness and return to use was obtained from medical records, as well as referring veterinarians, owners and trainers by telephone conversations and/or email. Long-term outcomes were obtained for 109 horses. There was no significant difference in resolution of lameness between the two techniques (79% DF vs. 88% NF), or in the percentage of horses returning to work 1–3 years postoperatively (83% DF vs. 93% NF). Horses treated with DF had higher ultrasonography scores compared with horses treated with neurectomy/fasciotomy. Horses treated with DF took longer to return to work compared to NF and received more non-surgical treatments in the recovery period. Post-operative complications were minimal with either technique. Use of either surgical technique for hindlimb proximal suspensory desmopathy can result resolution of lameness and return to athletic use.
