Ulnaris lateralis: tenotomy - flexural deformity

Contributor(s): Andy Bathe, Rachael Conwell, David Moll, Graham Munroe, Vetstream Ltd, Chris Whitton

Introduction

  • Sharp transection of the tendons of the ulnaris lateralis and flexor carpi ulnaris.
  • Permits sagittal realignment of the carpus.

Uses

Disadvantages

  • Considered by some clinicians to be a salvage procedure but a recent publication has documented excellent long-term results in mild and moderate degree cases.
  • More severe cases may require palmar carpal capsule and palmar carpal ligament release in addition, with a guarded to poor prognosis.

Prognosis

  • The prognosis for complete straightening of the palmar carpal angle and return to athletic potential depends on the degree of the carpal deformity at presentation.
  • Prognosis for grade 1 and 2 carpal flexural deformities is excellent - 100% and 89% respectively.
  • For grade 3 deformities it is 57%.
  • For those horses reaching over 3 years of ages post-surgery 72% of Thoroughbreds raced and 86% of other breeds fulfilled their intended use.
