Table 6-1. Pathologic Disorders of Joints and Related Structures
VetBooks.ir Name of Condition Pathology
Inflammation of bursa between tendon of m. biceps brachii and
Bicipital bursitis
humerus
Bog spavin Distension of joint capsule of hock; swelling on the craniomedial aspect
of hock
Bone spavin (jack spavin) Degenerative joint disease of distal intertarsal and tarsometatarsal joints
Bowed tendon (tenosynovitis) Inflammation, usually due to stretching, of digital flexor tendons and
their synovial sheaths caudal to cannon bone; usually thoracic limbs
affected
Bursitis Inflammation of any bursa
Capped elbow Inflammation of bursa over olecranon process (point of elbow)
Capped hock Inflammation of bursa over calcaneus (point of hock)
Carpitis (popped knee) Inflammation of carpal joint capsule and/or ligaments
Curb Thickening of long plantar ligament on caudal aspect of hock
Dislocation (luxation) Components of joint displaced
Fistulous withers Inflammation or infection with draining tract from bursa over spinous
process
Herniated (slipped) intervertebral Prolapse of nucleus pulposus of intervertebral disc, usually into the
disk vertebral canal; can cause spinal cord damage
Hunter’s bump Subluxation of sacroiliac joint
Laminitis (founder) Inflammation of laminae between hoof wall and distal phalanx
Navicular disease Inflammation of navicular bursa and bone, often with involvement of
associated tendons
Osselets Periostitis of proximal phalanx and/or distal metacarpus III, with
capsulitis of fetlock joint
Osteoarthritis Inflammation of any joint. Because term includes the bony elements of
joint, it is more descriptive than arthritis
Poll evil Inflammation or infection of bursa over atlas (C1)
Quittor Infection of collateral cartilages of distal phalanx
Ring bone Enthesiophyte formation in interphalangeal joints
Side bone Ossification of collateral cartilages of distal phalanx
Splints Inflammation and exostosis involving joint between cannon bone and
a splint bone (usually medial)
Sprain Stretching of ligaments of any joint
Stifling (upward fixation of the Inadvertent locking of patella over medial ridge of femoral trochlea;
patella) holds patella and hock in extension
Strain Excessive stretching of muscle and/or tendon
Subluxation Partial dislocation of any joint
Synovitis Inflammation of any synovial membrane
Thorough‐pin Synovitis of deep digital flexor tendon sheath proximal to hock
Trochanteric bursitis Inflammation of bursa between greater trochanter of femur and tendon
of middle gluteal muscle
Wind puffs (wind gall) Synovitis of fetlock joint or tenosynovitis of digital flexor tendons in
region of fetlock
