With some careful changes
to management routines,
ex-racehorses can have a
successful second career.
Saint Are (pictured) has
now turned to showing

A SECOND CHANCE
NATIONAL Hunt hero Saint Are
was twice placed in the Grand
National before retirement from
racing last year. Now based with
Justine Armstrong-Small, “Arnie”
has started a successful second
career in showing. We’ve stripped
him off to highlight potential
problem areas for other former
racehorses...



  1. LIMBS, JOINTS, FEET


CONFORMATIONAL problems
can give rise to racing injuries. Flat
front feet with low heels increase
the risk of tendon injuries, due to
strain on the back of the leg, while
offset knees, “back at the knee”
conformation and long pasterns
can all put extra pressure on joints.
In skeletally immature animals,
such as young Flat racehorses,
repetitive training can lead to
sore shins and stress fractures
— commonly to the tibia or
pelvis. These generally heal with
conservative management and
time out of training and, once


resolved, are unlikely to cause
future issues for ex-racehorses.
Acute subchondral bone pain
can cause distension (swelling)
of the fetlock joint, which can be
difficult to identify on radiographs
(X-rays). Chronic subchondral
bone injury can lead to a “pottery”
way of going and cause a “bunny-
hopping” action at canter. These
injuries often create less concern
in a different discipline, but can
lead to osteoarthritis.
Adaptations to bone
within joints can manifest as
osteoarthritis, causing spurs and
extra bone, or chip fractures.
Pain can occur in all the carpal
(knee) joints but specifically in the
middle carpal joint of racehorses,
causing discomfort on knee
flexion and a shuffling gait. These
changes may settle over time.
The superficial flexor tendons
of the forelimb are the most
common site of tendon injury,
from mild inflammation to
overt tendinitis and tears within
the tendon. These injuries are

often career-ending and require
extensive rest and rehabilitation.
Fibrous areas are likely to remain
in the tendon and may rule out
strenuous activity like eventing.
Suspensory ligament injuries
are more common in NH horses
and may remain undetected until
the limb is grossly swollen or there
is associated lameness. Long-term
issues may arise, especially with
lots of schooling in an arena.


  1. NECK AND SPINE
    NECK issues commonly occur
    in NH horses following falls.
    Fractures are either catastrophic
    or repair without lasting concerns,
    so should not adversely affect
    future athleticism.
    Spine issues can be more
    problematic. Impingement of the
    dorsal spinous processes (kissing
    spines) is not uncommon and may
    interfere with retraining. Surgical
    treatment may be necessary.

  2. PELVIS
    PELVIC stress fractures are
    common in young Flat racehorses,
    whereas traumatic pelvic injuries
    can occur in NH horses. Pelvic
    asymmetry, where the quarters
    are not muscled to the same
    degree (best viewed from behind),
    can occur following injury.
    This is unlikely to cause further
    problems once resolved, unless
    the asymmetry is very marked.

  3. FEET
    A COMBINATION of genetic
    conformation and inadequate
    hoof care means that many
    thoroughbreds have poor feet.
    Long toes and low heels contribute
    to lameness, notably superficial
    digital flexor tendon (SDFT)
    concerns, but primary foot pain is
    also a problem as thoroughbreds
    have thin soles which are
    susceptible to bruising and corns.
    Feet can be improved with
    good balance and heel support,
    along with the use of hoof pads
    and putty, in appropriate cases.

  4. WIND
    MINOR respiratory issues in
    training, such as infections and
    dust allergies, can cause loss of
    performance. This is of milder
    concern in less demanding
    disciplines, and inflammatory
    airway disease from allergens can
    be managed well.
    Other wind problems include
    laryngeal paralysis and bleeding
    from the nose when galloped
    (exercise-induced pulmonary
    haemorrhage). While few
    ex-racehorses will reach the
    athletic and respiratory capacity
    for wind conditions to be an issue,
    further investigation is wise if
    you hope to event the horse at
    higher levels.
    6. DIGESTION
    A DENTAL examination is a
    must, as is a faecal worm egg
    count if a de-worming history is
    not available. Ask your vet
    about an appropriate
    management programme.
    Racehorses in training are
    prone to gastric ulcers, due to a
    diet of high-cereal feed, minimal
    forage and lack of grazing. The
    only accurate method of diagnosis
    is gastroscopy, to examine
    the stomach lining. Targeted
    treatment can then be given, with
    dietary and management changes,
    which should resolve the ulcers
    and help prevent further issues.
    7. BEHAVIOUR
    STEREOTYPICAL behaviours
    (box walking, windsucking, crib-
    biting or weaving) may be present,
    but often become less severe
    once the horse is removed from
    the training environment. Even
    so, some ex-racehorses can be
    temperamentally unsuitable for
    some new homes. H&H
