Biceps Tenosynovitis

Examination of the biceps tendon Click to enlarge

Who is usually affected?
-Middle-aged, athletic dogs

What is happening?
-The major tendon crossing the front of the shoulder joint (biceps tendon) is strained or partially torn during physical activity
-Swelling and pain result from the injury and are aggravated by shoulder motion

Clinical signs you might notice in your pet
-Limping on a front leg, that may become worse after rest or exercise
-Head bobbing during walking or running
-Sitting or standing crookedly with a front leg turned outward

Diagnosis
-Careful orthopedic examination to identify the source of pain
-X-rays are used to evaluate the path of the biceps tendon and the shoulder region
-X-ray with a contrast liquid (arthrogram) may be needed to fully evaluate the shoulder joint

Surgical treatment
-Depending on the specifics of each case, recommended surgical options may include:
-Release of the biceps tendon from the shoulder blade with reattachment to the humerus
-Release of the biceps tendon via arthroscopy

Special postoperative care
-Patient activity is generally limited for 4-6 weeks following surgery, allowing time for joint inflammation to subside

Expected results after surgery
-Pain relief and a gradual return to good limb function
