Background
-
“Elbow Dysplasia” is often used to
describe three separate conditions of the elbow joint:
-
Ununited Anconeal Process (UAP)
-
Osteochondrosis Dissecans (OCD)
-
Fragmented Coronoid Process (FCP)
-
Young, intermediate to large breed dogs such
as the Rottweiler, German Shepherd Dog, Bernese mountain dog, Golden retriever
and Labrador retriever are most often affected.
-
Involvement of both elbows is common.
Anatomy
The elbow is comprised of three bones
along with tendons, muscles, and ligaments working together to provide
normal function of the joint:
Elbow Dysplasia
-
The exact cause of elbow dysplasia is not
known, but many theories exist.
-
Defects of the elbow bones lead to instability
and inflammation of the elbow joint.
-
Osteoarthritis, elbow pain and lameness are
the end result of elbow dysplasia
Symptoms
-
Foreleg lameness or, if both elbows are involved,
generally abnormal gait.
-
Exercise intolerance and reluctance to exercise
may also be noticed.
-
The elbow is often painful, thickened, swollen,
or unable to be completely flexed
Diagnosis is typically made based on symptoms,
exam findings and X-rays of both elbows.
Treatment Options
-
Medical treatment with pain relievers, “joint
formulas”,
physical therapy, leash exercise, and weight control is usually recommended
for dogs greater than 2 years of age.
-
Surgical treatment is generally recommended
dogs less than 2 years of age with minimal osteoarthritis.
Surgery for Elbow Dysplasia
Important Facts
-
Dogs less than 2 years of age with minimal
osteoarthritis are the best surgical candidates.
-
Dogs greater than 2 years of age with mild
to moderate DJD may also be surgical candidates, but expectations are limited
regarding post-operative improvement.
-
Most moderately affected dogs, with or without
surgery, are able to cope with the disease by having their weight and exercise
controlled and periodic use of pain relievers.
-
Regardless of the treatment, some arthritis
will develop in the elbow.
-
General anesthesia is utilized for the procedure
-
The faint scar remaining after surgery usually
becomes covered with fur again.
-
An overnight stay is required so discomfort
can be controlled with injectable medication.
Goals of Surgery
-
Confirm the pre-operative diagnosis.
-
Relieve pain associated with bone defects.
-
Decrease the amount of arthritis which will
inevitably develop in the elbow.
-
Limit stress put on the opposite limb and
other limbs and joints.
The Procedures
-
OCD and FCP require a single incision on the
inside of the elbow to remove the defects.
-
UAP requires two incisions; one on the outside
for the known defect and one on the inside to identify and remove other
defects which are present as much as 80% of the time.
-
Arthroscopic surgery has reportedly been used
in older dogs to remove arthritis. I do not advocate or perform this
procedure.
-
Total Elbow Replacement may be available in
the near future for older dogs with severe symptoms. This procedure
will require special training, equipment, and facilities.
The Recovery
-
The recuperative period typically lasts for
a total of 6-8 weeks.
-
Lameness is worse immediately following surgery
and improves slowly over the following weeks.
Post-Operative Care
-
Initially, exercise is limited to walks to
eliminate only.
-
Skin sutures and a light bandage are removed
10-14 days after surgery.
-
Leash exercise is gradually increased over
the following weeks; swimming is also fine.
-
Pain medication and antibiotics are administered
for several days after surgery.
-
No running, jumping or playing is permitted
for at least 8 weeks following surgery.
Expectations
-
Most pets are permitted to resume normal activity
several months after surgery.
-
Some dogs have lameness after surgery which
is controlled with medication.
-
In general, the younger the dog and the less
arthritis present at the time of treatment, the better the prognosis.
Cost of the Procedure
-
This typically includes examination, pre-anesthetic
bloodwork, anesthesia, surgery, hospital care, post-operative medications,
and two follow-up examinations.

Please ask your veterinarian for a detailed
surgical estimate for your pet.
