Summary
The goal of this study was to determine the incidence of musculoskeletal disorders
in a large canine population. Patient information was obtained from clinical cases
contributed to the Veterinary Medical Data Base (VMDB) by 16 veterinary teaching hospitals
during the ten year period of 1980 through 1989. The relative contribution of bone
diseases, joint diseases, and muscle-tendon-unit diseases was determined, and the
incidence of each musculoskeletal disease reported.
Nearly 24% of all patients in the source population had been affected by a disorder
of the musculoskeletal system, and over 70% of those diagnoses involved appendicular
structures. Diseases of joints, ligaments, and related structures contributed more
cases (47%) to this study than diseases of bones (39%) or muscle-tendon-units (14%).
Fractures made up the largest disease category, with pelvic fractures most common,
followed by femoral fractures, and fractures of the radius and/or ulna. Joint instability
and degenerative joint dis-
ease were also common diagnosis categories, affecting primarily the hip and stifle
joints. Common specific dis-ease entities included hip dysplasia, cruciate ligament
rupture, traumatic hip luxation and patellar luxation.
In this study we provided a comprehensive analysis of the canine musculoskeletal system.
The relative importance of joint disorders compared to those of bones and muscle-tendon-units
was illustrated. The incidence of most of the disorders described in this report had
not been well documented previously.
Patient information was obtained from the clinical cases of 16 veterinary teaching
hospitals during a 10-year period. The number of dogs with musculoskeletal disorders
was determined. The absolute and relative contribution of bone diseases, joint diseases,
and muscle-tendon-unit diseases is reported as well as the incidence of the specific
disease entities affecting the canine appendicular musculoskeletal system.
