ORIF stands for open reduction and internal fixation, a surgical procedure used to repair broken bones that can’t heal properly with a cast or splint alone. It’s one of the most common orthopedic surgeries performed, frequently used for fractures of the hip, ankle, wrist, spine, and shoulder. Together, these five sites account for about two-thirds of all fractures requiring hospitalization.
What “Open Reduction” and “Internal Fixation” Mean
The name describes exactly what happens in two steps. “Open reduction” means the surgeon makes an incision through the skin to directly see and access the broken bone, then manually repositions the fractured pieces back into their normal alignment. This is different from a “closed reduction,” where a doctor realigns bone fragments by manipulating them through the skin without any incision.
“Internal fixation” is the second step: once the bone fragments are back in position, the surgeon secures them with metal hardware placed inside the body. This hardware holds everything in place while the bone heals naturally over the following weeks and months.
When ORIF Is Needed
Most simple fractures heal fine with a cast, splint, or brace. ORIF becomes necessary when the break is too complex or unstable for those conservative approaches. You’re more likely to need ORIF if:
- The bone fragments are significantly displaced, meaning the broken pieces have shifted out of alignment and can’t be repositioned without surgery
- The bone has broken into several pieces (a comminuted fracture), making it impossible for a cast to hold everything together
- The broken bone has punctured through the skin (an open fracture), which requires surgical cleaning and stabilization
- The joint is unstable, especially in weight-bearing areas like the ankle or hip where proper alignment is critical for long-term function
Fractures near joints often require ORIF because even small misalignments at a joint surface can lead to chronic pain and arthritis down the road. ORIF has been considered the most reliable method for restoring the precise anatomy of a joint surface since the 1960s.
Types of Hardware Used
The metal hardware your surgeon chooses depends on which bone is broken, where the fracture sits, and how many fragments there are. The main categories include:
- Plates and screws: Metal plates are contoured to the shape of the bone and secured with screws on either side of the fracture. This is one of the most common setups, especially for arm, leg, and ankle fractures.
- Screws alone: For simpler fractures, screws can compress two bone fragments together without a plate.
- Rods and nails: Long metal rods are inserted through the hollow center of a bone (the marrow canal) to stabilize fractures in the shaft of the thighbone or shinbone.
- Wires and pins: Thin metal wires or pins are used for smaller bones or to temporarily hold fragments while other hardware is placed. Tension band wiring, for instance, converts pulling forces into compressive forces that actually help healing.
Most hardware is made from titanium or stainless steel. Some newer devices are made from materials designed to be gradually absorbed by the body, eliminating the need for removal later.
What Happens During Surgery
ORIF is performed under general anesthesia or regional anesthesia (where only part of your body is numbed). The surgeon makes an incision over the fracture site, moves soft tissue aside to expose the broken bone, and then works to reposition each fragment into its correct anatomical position. Specialized clamps hold everything aligned while the surgeon checks the reduction visually and sometimes by feel, running a finger along the bone surface to confirm there’s no gap or step between fragments.
Once the alignment looks right, the surgeon secures the fragments with the chosen hardware. For fractures near a joint, the surgeon may inspect the joint surface directly to confirm the pieces are perfectly flush. X-rays taken during surgery verify the final position before the incision is closed. The whole procedure can take anywhere from one to several hours depending on the complexity of the fracture.
Recovery and Weight Bearing
Recovery timelines vary significantly based on which bone was broken and how severe the fracture was. For a typical ankle fracture treated with ORIF, the standard rehabilitation protocol starts with partial weight bearing, usually limited to about 20 kilograms of pressure (roughly the weight of resting your foot on the floor) for the first three to six weeks. You’ll use crutches and a walking boot during this phase.
After that initial period, you gradually increase the load on the leg with a goal of reaching full weight bearing by 8 to 10 weeks after surgery. Some newer locking plate systems allow a faster timeline, with patients progressing to full weight bearing as early as three weeks. Your surgeon will decide your specific schedule based on the hardware used and how stable the repair is.
Physical therapy typically begins within the first few weeks, starting with gentle range-of-motion exercises and progressing to strengthening work as the bone heals. Most fractures take 6 to 12 weeks to show solid healing on X-rays, though full recovery of strength and function often takes several months longer.
Risks and Complications
Like any surgery, ORIF carries risks. The primary trade-off is that while it provides excellent bone alignment, it requires cutting through soft tissue to get there, which adds its own healing burden.
Surgical site infection is the most closely tracked complication. A large meta-analysis of over 5,800 patients found an overall infection rate of about 4.2% to 4.5% following ORIF, with rates slightly higher in American studies (around 7.3%) compared to European and Asian ones (about 4.2% to 4.3%). Other potential complications include nerve injury near the surgical site, hardware failure or loosening, delayed bone healing (nonunion), and blood clots.
ORIF vs. External Fixation
The main surgical alternative to ORIF is external fixation, where metal pins are inserted through the skin into the bone and connected to a rigid frame outside the body. External fixation causes less damage to soft tissue around the fracture, which can be an advantage when the skin and muscles are already badly injured.
However, a meta-analysis comparing the two approaches for complex lower leg fractures found that external fixation carried higher rates of superficial infection, malunion (bone healing in the wrong position), and nonunion (bone failing to heal). ORIF, on the other hand, had a higher rate of unplanned hardware removal. The two methods showed no significant difference in deep infection rates, overall clinical outcomes, development of arthritis, or how long the bone took to heal. In general, ORIF is preferred when soft tissue condition allows it, because it gives the surgeon the most precise control over bone alignment.
Does the Hardware Need to Come Out?
In many cases, internal fixation hardware stays in your body permanently without causing problems. Routine removal is not recommended. The decision to take hardware out is made on a case-by-case basis, typically when the hardware is causing pain, irritation, or limiting movement in a nearby joint.
Hardware removal is not a trivial procedure. It carries its own risks, including nerve or blood vessel injury, refracture of the bone, and recurrence of the original deformity. When hardware is removed specifically for pain relief, the results are unpredictable and depend on both the type of implant and where it was placed. There is no strong evidence that leaving hardware in place increases the risk of allergic reactions, cancer, or problems with metal detectors.
