Iliopsoas injury in agility dogs: diagnosis and management
5-year-old Border Collie competing in agility, with intermittent left hindlimb lameness after training and reduced jumping performance. There is focal inguinal pain on hip extension with internal rotation.
What is the most appropriate approach?
chevron_right Show answer and explanation
A. It is hip dysplasia: extended-view radiographs and surgery
Hip extension is also painful in dysplasia, but focal pain on iliopsoas palpation during hip extension and internal rotation points to a muscle or tendon injury.
B. Two weeks of rest with an NSAID and then a direct return to competition
Iliopsoas injuries frequently recur if the dog returns to activity without progressive rehabilitation; the tissue takes weeks to months to regain strength.
C. Confirm with ultrasound, examine the stifles carefully (cruciate ligament rupture may coexist) and plan sporting rest, analgesia and progressive rehabilitation before returning to competition
Correct. Pain on palpating the iliopsoas near the lesser trochanter with the hip in extension and internal rotation is characteristic. Ultrasound confirms and grades the lesion. It often accompanies stifle disease, which must be looked for. Rehabilitation includes gentle stretching, strengthening and a gradual return to activity.
D. Corticosteroid injection into the tendon and competition the following week
Intratendinous corticosteroids weaken the tendon and increase the risk of rupture; competing so soon masks pain and favours relapse.
lightbulb Key takeaway
In sporting dogs overuse injuries are common and recurrent: plan a staged return to sport with objective criteria (no pain, symmetrical muscle mass, normal gait), warm-up and conditioning.
