Straight sesamoidean ligament: desmitis

pequis

Introduction

Pathogenesis

Etiology

  • Tendon fatigue.
  • Direct trauma.

Predisposing factors

General

Pathophysiology

  • Forelimb > hindlimb.
  • Straight sesamoidean ligament (SSL) injury is uncommon and may not result in pastern swelling or heat in the acute phase.
  • May occur alone or with oblique sesamoidean ligament (OSL)   Oblique sesamoidean ligament: desmitis  and/or other soft tissue injuries   Proximal sesamoid: sesamoiditis  .
  • Subsequently:
    • Swelling may develop, but can be difficult to palpate with distal lesions.
    • Pain may be elicited on palpation in the palmar midline of the pastern region.
  • Concurrent effusion may occur in the digital flexor tendon sheath (DFTS).
  • Suspensory ligament (SL) rupture may   →    loss of tension in SSL   →    instability or palmar/plantar luxation of the proximal interphalangeal (PIP) joint.
  • Avulsion fracture of the insertion of the SSL to the proximal apsect of the middle phalanx has been described   →    areas of periosteal proliferative change.
