Elbow Surgery (FMCP, UAP, OCD, Incongruity)

Elbow dysplasia is a major cause of forelimb lameness in young, growing dogs — breeds like Labrador Retrievers, Golden Retrievers, Rottweilers, Bernese Mountain Dogs, and German Shepherds are disproportionately affected. Surgical intervention is recommended when:

• A loose fragment (coronoid, anconeal, or OCD flap) is confirmed on CT or arthroscopy — leaving fragments in place perpetuates ongoing cartilage damage
• An ununited anconeal process is identified in a young dog where reattachment is still feasible
• Joint incongruity is contributing to mechanical overload and is amenable to correction

Early surgery (while cartilage is still relatively intact) consistently produces better long-term outcomes than waiting. Surgery does not cure the arthritis already present but stops the progression driven by the mechanical problem.

Surgical technique is tailored to the specific diagnosis established by CT imaging and, in many cases, confirmed by arthroscopy (a minimally invasive camera in the joint):

• Fragmented medial coronoid process (FMCP) — the loose fragment is removed arthroscopically or through a small incision; the underlying diseased bone surface is often treated by burring (abrading) to stimulate healing
• Ununited anconeal process (UAP) — in young dogs, the anconeal process can sometimes be reattached with a lag screw if diagnosed before extensive cartilage damage; if reattachment is not viable, the fragment is removed
• OCD flap — the detached cartilage flap is removed and the underlying exposed bone is curetted (scraped) to stimulate fibrocartilage fill-in
• Joint incongruity / dynamic proximal ulnar osteotomy (DPUO) — a cut in the ulna redistributes load within the joint and allows the bones to remodel into better alignment

Arthroscopy is preferred for fragment removal where feasible — it provides superior visualization and smaller incisions with faster recovery compared to open arthrotomy.

CT imaging is the gold standard for characterizing elbow dysplasia — it provides three-dimensional detail of fragment size and location, cartilage damage, and joint congruity that X-rays alone cannot capture. Both elbows are typically scanned, as bilateral disease is common. Pre-anesthetic bloodwork clears the patient for anesthesia. Young dogs with elbow dysplasia are often not yet arthritic but may have subtle foreleg lameness or exercise intolerance — early evaluation when these signs first appear gives the best chance of intervening before significant cartilage is lost. Fast your dog from food the evening before surgery, and the team will provide post-operative instructions for bandage care if a small surgical wrap is applied.

Recovery from elbow surgery, particularly arthroscopic procedures, is generally faster than after open joint surgery. A typical timeline:

• Days 1–5: mild swelling and stiffness; pain medication and restricted activity; the dog typically uses the leg within a day or two; cold-packing the elbow reduces inflammation
• Weeks 1–4: controlled leash walks gradually increase in length; no running, jumping, or rough play; follow-up at 2 weeks for incision or portal site check
• Weeks 4–8: a recheck exam and possible X-rays assess joint comfort and healing; activity continues to increase under guidance; for UAP reattachment or osteotomy cases, full healing takes longer
• Long-term: the arthritis already present at the time of surgery will be managed with joint supplements, appropriate exercise, and weight control throughout the dog's life

Keeping the dog lean is one of the most powerful long-term strategies — every extra pound of body weight accelerates elbow arthritis progression.

Elbow surgery significantly reduces pain and slows arthritis progression in most patients — but it does not provide a completely normal joint. The degree of pre-existing cartilage damage at the time of surgery strongly influences the long-term outcome. Possible complications include infection, incomplete fragment removal (occasionally requiring revision), and failure of a UAP reattachment screw. Most dogs show noticeable improvement in gait and comfort within weeks of surgery. Lifelong arthritis management — anti-inflammatories during flares, joint supplements, controlled exercise, and weight management — remains important regardless of how well the surgery goes. The surgical team monitors both elbows since bilateral disease is common.
