Bicipital tenosynovitis

Contributor(s): Joseph Harari

Introduction

  • Cause: ?trauma (often repetitive), ?degenerative joint disease (DJD) secondary toosteochondrosis osteochondrosis (OCD), idiopathic.
  • Incidence: older, medium to large breeds - dogs which lead active lives.
  • Signs: forelimb lameness which deteriorates with excessive exercise but improves with rest.
  • Diagnosis: difficult; radiographic changes are secondary.
  • Treatment: depends on severity of lameness and response to initial conservative therapy.
  • Prognosis: fair.

Pathogenesis

Etiology

  • ?Trauma - often of a repetitive nature (tendon strain, rupture).
  • ?Degenerative joint disease (DJD) Arthritis: osteoarthritis - adhesions form between tendon and joint capsule in region of intertubercular groove.
  • Entrapment of joint mice (following osteochondrosis).
  • Idiopathic.

Pathophysiology

  • Inflammation of biceps brachii tendon.
  • Onset of lameness may be acute, following a particularly active period of exercise, eg digging, scrambling up steep banks.
  • Lameness may be insidious/chronic.
  • Pain evident on manipulation of shoulder: flexion/full extension/direct pressure applied to tendon.
  • New bone deposition within intertubercular groove/mineralization within tendon of supraspinatus muscle - ?significant.
