Surgery for complex elbow fracture-dislocations

Some complex elbow injuries that are stable after the joint is put back in place can be treated without surgery, with protected motion and close follow-up. Surgery is generally recommended when the elbow is unstable, or when the fracture pattern is one that needs to be fixed or replaced to restore stability.

The goal of surgery is a stable elbow that can begin moving relatively early, because early, protected motion helps limit the stiffness these injuries are prone to. A fuller description of the injuries themselves is on the complex elbow fracture-dislocation condition page.

Rather than a single fixed procedure, surgery for these injuries is assembled from several steps, and which steps are used depends on the injury. In general terms, the surgeon works to restore each injured stabilizer so that, together, they hold the elbow in place through a functional range of motion. Common elements include:

• Managing the coronoid fracture — the bony prominence at the front of the ulna that resists the elbow sliding backward — which may be fixed or otherwise addressed depending on its size and the fragments
• Treating the radial-head fracture — either fixing it (when it can be reliably reconstructed) or replacing it (when it is too broken to fix), to restore its contribution to stability
• Repairing the torn ligaments, most often the lateral collateral ligament complex on the outer side, and sometimes the medial (inner) ligament
• Adding further stabilization selectively — for example an external device that holds the elbow aligned while healing begins — in injuries that remain unstable after the above

The radial head contributes to the elbow's stability, so restoring it is often part of the operation. When the fracture can be reliably reconstructed, it is fixed. When it is too fragmented to fix dependably, the radial head may be replaced with an implant so that its stabilizing role is restored.

Neither fixing nor replacing is universally preferable — the choice depends on how reconstructable the fracture is and the surgeon's judgment during the operation. The radial-head replacement page covers that specific option in more detail. This page names no implant brands and makes no claim that one approach is better in every case.

Because these injuries combine different fractures and different degrees of ligament damage, the exact operation — which structures are fixed, repaired, or replaced, and in what order — varies from person to person, and can even change during surgery as the injury and the elbow's stability are assessed directly.

For that reason, this page describes general building blocks rather than a set recipe. Your surgeon determines the plan that restores stability for your specific injury, and your operative note records what was actually done.

Rehabilitation after these operations walks a deliberate line between protecting the repaired structures and restoring motion, because both instability and stiffness are risks. In general terms, the elbow is protected early — often in a splint or brace, sometimes within a defined safe arc of motion your surgeon sets — and protected motion is introduced relatively early to limit stiffness. Strengthening is added gradually as healing allows, and activity is advanced in stages.

The pace and the specific restrictions depend on what was injured and what was done, and are set by your surgeon; some stiffness is common. The terrible-triad rehabilitation protocol below describes the general shape of recovery after surgical treatment of that pattern; your operative note and your surgeon's instructions take precedence.

Surgery for a complex elbow injury carries the considerations of a significant operation. The possibilities below are for discussion with your surgeon and are not a complete list:

• Stiffness or loss of some motion, which is common with these injuries
• Recurrent or residual instability of the elbow
• Nerve symptoms or, less commonly, a nerve injury
• Extra bone forming around the elbow (heterotopic ossification) that can limit motion
• A fracture not healing, or a problem with the fixation or an implant
• Infection and wound-healing problems
• Later elbow arthritis
• A need for further treatment or surgery

The goal of surgery for a complex elbow fracture-dislocation is a stable elbow that can move and be useful for daily life. These are serious injuries; recovery is gradual and protected, some stiffness is common, and results are individual — no particular range of motion, strength, or timeline can be guaranteed. The plan is matched to your specific injury after a clear conversation with your surgeon.
