Overview
The ankle works like a ring. The lower end of the tibia (tibia) forms the inner ankle bump, and the thin outer leg bone (fibula) forms the outer bump. Between them sits the talus, the main ankle bone. Surgeons call this snug fit the mortise. Like any ring, the ankle can take a single crack and hold its shape. But if the ring breaks in more than one place, or the talus shifts off-center, the cartilage surfaces stop meeting squarely. Load then travels through the joint unevenly. That uneven loading speeds up cartilage wear. It is the main reason a poorly treated ankle fracture so often leads to arthritis.
Open reduction and internal fixation, called ORIF, is the operation that puts the ring back together and holds it there while the bone heals. "Open reduction" means the surgeon makes an incision to see and realign the broken pieces directly. "Internal fixation" means plates, screws, or rods placed inside the body hold the bone in position. Once the pieces are secured, the shape of the ankle is restored. The cartilage surfaces can then meet correctly with each step.
Not every ankle fracture needs ORIF. A single crack that has not shifted, with the ring intact, can often heal in a cast or a boot. Surgery is the right choice when the fracture pattern is unstable, when the talus has shifted inside the ring, or when the syndesmosis has been disrupted. The syndesmosis is the fibrous joint that binds the tibia and fibula together just above the ankle. Your surgeon will review your X-rays, and often stress views, to decide whether the ankle will hold its position reliably without fixation.
When surgery is needed, getting the ankle back into near-perfect alignment matters. Even a small sideways shift of the talus concentrates pressure on the cartilage and speeds up wear. That is why we accept very little malalignment, and why surgery is strongly favored for unstable patterns.
How the Procedure Works
The operation is planned around your specific fracture pattern. The way the foot twisted at the moment of injury decides which bones broke, and the repair follows that map. A broken fibula is reached through an incision along the outer ankle. The bone is brought back to its original length and rotation, then held with a plate and screws. Length and rotation matter more than most patients realize. A fibula that heals even slightly short or rotated pushes the talus sideways and puts stress exactly where the cartilage should not bear it.
A break of the inner ankle bump is fixed through a small incision on the inside of the ankle with screws or a small plate. If the syndesmosis is unstable, we place one or two screws or a flexible suture-button implant across the two bones. That holds them together while the ligaments heal. We check alignment with live X-ray during surgery and stress-test the repair before closing. Any remaining instability is caught on the table, not on the first X-ray after surgery.
When to Consider Ankle ORIF
We generally offer ankle fracture ORIF when imaging and the exam show that the fracture will not reliably hold its shape in a cast or boot. The typical picture includes:
Displaced fibular fracture
A fibula that sits short, rotated, or shifted sideways changes how the talus meets the tibia. It cannot be trusted to heal that way.
Bimalleolar or trimalleolar pattern
Fractures that involve both sides of the ankle, or the back of the tibia as well, break the ring in more than one place. They are unstable by nature.
Syndesmotic disruption
Widening between the tibia and fibula on exam or stress imaging calls for fixation across the syndesmosis to restore the ring.
Talar shift on weight-bearing films
Any shift of the talus under body weight is a direct reason to operate. The ankle has already shown it cannot hold position.
Open fracture or soft-tissue compromise
Tight skin over the fracture or an open wound calls for urgent realignment and fixation to protect the soft tissue.

Weight-Bearing After Repair
Controlled load is part of how bone heals. Once the fracture is held with hardware, gentle weight through the leg stimulates the biology that builds new bone. Taking all weight off a fixed fracture for too long can actually slow healing and stiffen the joints above and below. Full body weight right away, though, can overload the repair before the bone has caught up. The right answer sits in between. Your surgeon sets a step-by-step weight-bearing plan based on your fracture pattern, the strength of the fixation, your bone quality, and how the repair looks on X-rays after surgery. We tell you exactly how much weight the leg can take, when to advance, and what to watch for.
Risks & Why We Still Recommend It
Every operation carries risk. This procedure is offered because the condition, when left untreated, can cause an ankle that heals out of line and goes on to post-traumatic arthritis, since even a few degrees of tilt in the talus speeds cartilage wear. The decision to proceed weighs the risks of surgery against the limitations the condition places on daily function. Surgery does not remove risk; it addresses a problem that is otherwise progressive. Whether it is appropriate is determined for each patient in consultation with the surgeon.
The risks we discuss with you before ankle fracture ORIF include:
- bleeding and infection (the skin and soft tissue over the ankle are thin, so infection risk is higher than at many other sites)
- anesthesia risk
- blood clot in the leg or lung
- stiffness
- hardware irritation that may need later removal
- problems with wound healing
- arthritis in the joint over time
Surgery makes sense when your ankle fracture is displaced or unstable. That includes bimalleolar and trimalleolar patterns, which involve two or all three sides of the ankle, and injuries where the syndesmosis has been disrupted. If that picture does not fit you, we do not offer this operation.
Frequently Asked
questions we hear in clinicDoes every ankle fracture need surgery?
No. A single crack that has not shifted, with the ring of the ankle intact, can often heal in a cast or a boot. Surgery is the right choice when the fracture pattern is unstable, when the talus has shifted inside the ring, or when the syndesmosis has been disrupted. Your surgeon reviews your X-rays, and often stress views, to decide.
Why does even a small shift matter so much?
Even a small sideways shift of the talus concentrates pressure on the cartilage and speeds up wear. A fibula that heals even slightly short or rotated pushes the talus sideways and puts stress exactly where the cartilage should not bear it. That is why we accept very little malalignment.
When can I put weight on my ankle?
Controlled load is part of how bone heals, but full body weight right away can overload the repair. Your surgeon sets a step-by-step weight-bearing plan based on your fracture pattern, the strength of the fixation, your bone quality, and how the repair looks on X-rays after surgery. We tell you exactly how much weight the leg can take, when to advance, and what to watch for.
What is the syndesmosis, and why does it get its own screws?
The syndesmosis is the fibrous joint that binds the tibia and fibula together just above the ankle. If it is unstable, we place one or two screws or a flexible suture-button implant across the two bones to hold them together while the ligaments heal.
Will the plates and screws come out later?
One of the risks we discuss is hardware irritation that may need later removal. Alignment and the repair itself are checked with live X-ray during surgery and stress-tested before closing, so any remaining instability is caught on the table.
What happens if the ankle heals crooked?
Left untreated, a crooked ankle goes on to develop post-traumatic arthritis. Even a few degrees of tilt in the talus speeds up cartilage wear, and that uneven loading is the main reason a poorly treated ankle fracture so often leads to arthritis.
