Overview
The ankle is a hinge in which the two malleoli, the bony knobs at the ends of the fibula and tibia, hold the talus in its slot. When one or both break and shift, the talus tilts, and a joint that heals even a millimeter or two out of place wears out. Open reduction and internal fixation (ORIF) puts the broken bones back in their exact anatomic position and holds them with a plate and screws so the ankle heals aligned. The purpose is a stable, straight ankle that moves normally and does not develop early arthritis.
Dr. O'Donnell fixes ankle fractures as an outpatient or short-stay procedure, with patients going home the same day in a splint on crutches.
Who It's For
Surgery is recommended for an ankle fracture that is displaced or unstable: a fibula fracture with the talus shifted out of its slot, fractures of both malleoli, a fracture with a torn deltoid ligament on the inner side, a broken posterior malleolus large enough to affect the joint, or a syndesmosis injury where the ligaments holding the tibia and fibula together have torn and the fibula has separated.
A stable, non-displaced fracture of the lateral malleolus alone, with the deltoid ligament intact and the talus sitting centered, heals well in a boot without surgery, walking as tolerated within a few weeks. Surgery is sometimes delayed for one to two weeks when the ankle is badly swollen or blistered, since operating through compromised skin raises the wound risk; the ankle is held reduced in a splint in the meantime.
A fracture line on an X-ray is not by itself a reason to operate. Dr. O'Donnell fixes an ankle when the displacement or instability on imaging matches the exam, including tenderness and stress testing on the inner side, and the pattern is one that does not heal in position in a boot. The ankle fracture page describes how stability is judged.
What the Procedure Involves
The operation is done under a nerve block with sedation or a general anesthetic. Through an incision along the outer side of the ankle, Dr. O'Donnell exposes the fibula fracture, realigns the ends exactly, restoring the bone's length and rotation, and secures them with a lag screw across the fracture and a contoured plate along the bone. If the medial malleolus is broken, a second incision on the inner side allows it to be fixed with two screws; a displaced posterior malleolus fragment is fixed with screws from the front or back. The syndesmosis is then tested under X-ray by stressing the fibula; if it is unstable, the fibula is held to the tibia with a screw or a flexible suture-button device while the ligaments heal. The procedure takes about an hour to 90 minutes, and the ankle goes into a well-padded splint.
Risks & How They Are Minimized
Wound problems are the risk particular to ankle fractures, because the skin over the malleoli is thin and swells: they are minimized by waiting for the swelling to settle before surgery, placing incisions carefully, and strict elevation for the first two weeks. Infection is uncommon and is addressed with a pre-incision antibiotic. Post-traumatic arthritis is the long-term risk and is driven by the accuracy of the reduction, which is why it is confirmed with X-ray at every step. Stiffness is limited by early ankle motion out of the splint once the incisions have healed. Deep-vein thrombosis is a real concern with a non-weight-bearing leg and is prevented with a blood thinner, toe and knee motion and early mobility. Numbness over the outer foot from a skin nerve near the fibula incision is occasional and usually fades. Hardware irritation over the fibula plate is the most common late complaint and is resolved by removing the plate after the fracture has healed.
Recovery & Rehabilitation
Weight bearing is protected while the fracture heals and advanced according to the fixation and whether the syndesmosis was repaired, which needs a longer non-weight-bearing period. Early swelling control and gentle motion reduce stiffness.
| Phase | Timing | What happens |
|---|---|---|
| Protection | Weeks 0–2 | Non-weight-bearing on crutches in a splint, then a boot. Toe curls, knee and hip motion, straight-leg raises, elevation, general conditioning. No ankle motion until the incisions have healed. Advance with wound healing and controlled swelling. |
| Motion | Weeks 2–6 | Still non-weight-bearing until about 6 weeks, in the boot for protection. Active ankle motion in all directions out of the boot, gentle stretching within comfort, scar management. Advance with improving motion and X-rays showing healing. |
| Weight bearing & strength | Weeks 6–12 | Weight bearing advanced per X-ray; boot weaned to a shoe and crutches discarded. Band strengthening, calf raises, balance and proprioception, gait training. Advance with pain-free full weight bearing, a normal gait and radiographic union. |
| Return to activity | Months 3–6 | Progressive strengthening and balance, running and agility progression as tolerated, sport-specific drills. Return to sport typically at 3 to 6 months with symmetric strength and balance. |
Desk work is possible within about a week with the leg elevated. Driving waits until out of the boot with full weight bearing, about 8 to 10 weeks for a right ankle. Cycling and swimming from about 8 weeks, running from about 3 months, and cutting sport at 4 to 6 months.
Protocol summary
Precautions: non-weight-bearing with crutches for about 6 weeks, longer if the syndesmosis was fixed; splint and then a walking boot, with frequent elevation to control swelling; no forced ankle range of motion early; progression to weight bearing only when cleared on X-ray.
Criteria: the protection phase ends with healed incisions and controlled swelling; weight bearing is advanced once X-rays show healing, and the boot is weaned to a shoe once weight bearing is full without pain, gait is normal and the fracture has united; return to sport requires symmetric strength and balance, typically at 3 to 6 months.

How long are you non-weight-bearing after ankle fracture surgery?
About 6 weeks on crutches with no weight on the leg, longer if the syndesmosis was fixed, because those ligaments heal more slowly than bone. Weight bearing is then advanced in the boot over weeks 6 to 12 as X-rays confirm healing.
When can I walk normally after ankle ORIF?
Full weight bearing in the boot is usually reached around 8 weeks, and a normal gait in a shoe by about 10 to 12 weeks once the fracture has united and calf strength is returning. Swelling at the end of the day is normal for several months.
Do I need surgery for a broken ankle?
Only if the fracture is displaced or unstable. A stable, non-displaced fracture of the outer ankle bone with the talus centered in its slot heals in a boot without surgery. Fractures of both sides of the ankle, fractures that have shifted, and syndesmosis injuries are generally fixed, because an ankle that heals even slightly out of position wears out early.
When can I drive after ankle fracture surgery?
For a right ankle, once you are out of the boot, bearing full weight and able to brake hard without hesitation, usually 8 to 10 weeks. For a left ankle with an automatic transmission, once you are off narcotic pain medication and can get in and out of the car safely, often within 2 to 3 weeks.
Will the plate and screws need to come out?
Usually not. Most hardware stays permanently without causing trouble. The fibula plate sits directly under the skin and irritates some patients with shoes or boots; if it does, it is removed as a short outpatient procedure after the fracture has healed, generally a year or more out.
How long until I can run after ankle ORIF?
Running usually begins around 3 months, once the fracture has united on X-ray, gait is normal and calf strength and single-leg balance are close to the other side. Agility, cutting and sport-specific work follow, with return to sport typically at 3 to 6 months depending on the fracture pattern and the sport.
