Fracture Fixation Surgery

Introduction

If you or someone close to you has had a serious bone fracture, there is a good chance a surgeon has talked about fixing the bone with an operation rather than treating it in a cast alone. That operation is called fracture fixation surgery. It is one of the most common surgeries in orthopaedics and trauma care, and it is used every day in hospitals around the world to help broken bones heal in the correct position.

This article is written for adults who already have a fracture diagnosis, or who are caring for a child or family member with a fracture, and who want to understand what the surgery involves, how it is decided, and what recovery looks like. It explains the different types of fixation, how surgeons choose between them, what happens before, during, and after the operation, and what to expect in the weeks and months that follow.

Because every fracture is different — the bone, the pattern of the break, the patient’s age, and other health conditions all matter — the article describes general patterns rather than a single recipe. Your own surgical team will guide the specific decisions that apply to your situation.

What Is Fracture Fixation Surgery?

A fracture is a break in a bone. When a bone breaks, the body begins to heal it automatically by laying down new bone tissue across the break. For healing to happen properly, the broken ends need to be held in the right position and kept reasonably still. In many simple fractures, a cast or splint is enough to do this. In more complex fractures — when the bone fragments have shifted, when there are several pieces, when a joint surface is involved, or when the bone is unstable — the surgeon may need to put the pieces back into place and hold them there with metal implants.

Fracture fixation surgery is the operation that achieves this. The surgeon repositions the broken bone fragments (a step called reduction) and then secures them with hardware such as plates, screws, rods (intramedullary nails), pins, wires, or an external frame. The hardware holds the bone steady while natural healing closes the fracture line. When the surgery uses internal hardware placed under the skin, it is often called open reduction and internal fixation, or ORIF.

The goals of the operation are to:

• Restore the bone’s normal shape and alignment
• Hold the fragments stably so healing can occur
• Protect nearby joints, nerves, and blood vessels
• Allow earlier movement of the limb, which helps prevent stiffness and muscle wasting
• Reduce the risk of long-term deformity, non-healing, or arthritis

The American Academy of Orthopaedic Surgeons (AAOS) and the AO Foundation, which sets widely-followed international principles of fracture surgery, describe the same basic aims: anatomical reduction, stable fixation, preservation of blood supply, and early functional movement.

Why Is Fracture Fixation Surgery Performed?

Not every broken bone needs surgery. A surgeon usually considers fixation when one or more of the following is present:

• Displaced fractures — the bone fragments have moved out of their normal alignment and would not heal correctly in a cast.
• Unstable fractures — the broken ends shift easily and cannot be reliably held still without hardware.
• Comminuted fractures — the bone has broken into several pieces.
• Open fractures — the bone has broken through the skin. These need urgent surgery to clean the wound and stabilise the bone.
• Intra-articular fractures — the break extends into a joint surface. Even small steps in the joint surface can lead to arthritis later, so accurate repositioning is important.
• Fractures with nerve or blood vessel injury — surgical exploration and stabilisation may be needed.
• Fractures that have not healed (non-union) or have healed in the wrong position (malunion) — these may need a corrective operation.
• Certain bones where conservative treatment heals poorly — for example, displaced fractures of the hip in older adults are almost always treated surgically because immobilisation causes serious complications.
• Pathological fractures — bones weakened by tumours, infection, or severe osteoporosis often need fixation even when the break itself is not severe.

Common bones treated with fracture fixation surgery include the hip, femur (thigh bone), tibia (shin bone), ankle, wrist, forearm, humerus (upper arm), clavicle (collarbone), pelvis, and spine. Fractures of the hand, foot, and small bones around joints are also frequently fixed surgically when displaced.

Who Is a Candidate?

The decision to operate is made by an orthopaedic or trauma surgeon after reviewing the fracture pattern on imaging and considering the whole patient. Factors that influence the decision include:

• The exact bone involved and the fracture pattern
• How displaced or unstable the fragments are
• Whether a joint is involved
• Whether the skin and soft tissues around the bone are intact
• The patient’s age, bone quality, and general health
• The patient’s usual activity level and functional needs
• Other injuries from the same accident
• Risks from anaesthesia and surgery

In older adults with hip fractures, for example, surgery is usually carried out within 24 to 48 hours of admission because earlier fixation is linked to better outcomes. In younger patients with high-energy injuries from road accidents or falls from height, the timing depends on overall stability and whether other organ injuries need attention first.

Some patients are not good candidates for surgery — for example, those who are too unwell to tolerate anaesthesia, or those whose fractures will heal predictably without it. In these situations, non-surgical treatment may be safer.

Alternatives to Surgery

Many fractures heal well without an operation. Non-surgical options include:

• Casting — a rigid plaster or fibreglass cast holds the bone still while it heals. This is the standard treatment for many wrist, forearm, ankle, and lower leg fractures that are in acceptable alignment.
• Splinting and bracing — removable splints or functional braces are used for some fractures that need support but not full rigid immobilisation.
• Traction — a steady pull is applied to a limb to keep bone fragments aligned. This is less common today as a definitive treatment but is still used as a temporary measure before surgery in certain injuries.
• Closed reduction — the surgeon manipulates the bone back into position without making an incision, then applies a cast or splint. This is often used for displaced wrist or ankle fractures that can be realigned and held without hardware.
• Watchful management — some hairline or stable fractures heal with rest, protected weight-bearing, and time.

The surgeon’s judgement on whether surgery or a non-surgical approach is the better path depends on the likelihood that the bone will heal in good alignment, the risk of stiffness or loss of function if the limb is kept still in a cast for many weeks, and the patient’s own goals. Both surgery and casting carry trade-offs, and these are usually discussed in detail before a decision is made.

Surgical Approaches

Fracture fixation is not a single operation. There are several approaches, each suited to different bones and fracture patterns. A surgeon may use one approach or combine them.

Internal Fixation

Internal fixation means the hardware sits inside the body, under the skin. It is the most common approach.

• Plates and screws. A flat metal plate is placed against the bone and held in place with screws. Plates are widely used for fractures of the forearm, wrist, ankle, collarbone, humerus, and bones around joints. Modern locking plates have threaded screw holes that grip the screws tightly, giving stable fixation even in softer or osteoporotic bone.
• Intramedullary nails (rods). A long metal rod is passed down the hollow centre of a long bone such as the femur or tibia. The nail is locked in place with screws at each end. Intramedullary nailing is the standard approach for many shaft fractures of the thigh and shin bones because it allows early weight-bearing and avoids large incisions over the fracture itself.
• Screws alone. For some fractures — for example, certain hip, ankle, or wrist fractures — screws inserted across the break are enough to hold the fragments together.
• Pins and wires (K-wires). Thin metal pins are used in smaller bones such as those of the hand or foot, in some wrist fractures, and frequently in children. They may be left protruding through the skin for later removal, or buried under the skin.
• Tension band wiring. A combination of wires and pins used for fractures such as those of the kneecap or elbow, where strong muscle pull would otherwise separate the fragments.

Implants are made of medical-grade stainless steel or titanium alloys. They are designed to remain in the body long-term, although some are removed later if they cause irritation.

External Fixation

External fixation is used when:

• The skin and soft tissues around the fracture are badly injured or contaminated (often in open fractures)
• The patient has multiple injuries and a quick stabilisation is needed before a longer operation can be done safely
• The bone has been lost or shortened and needs to be gradually lengthened or repositioned over time
• There is severe swelling that makes immediate internal fixation unsafe

An external fixator may be a temporary measure (replaced by internal fixation once the soft tissues recover) or a definitive treatment that stays on until the bone has healed. Circular frames such as the Ilizarov frame are a specialised form of external fixation used for complex reconstruction and limb lengthening.

Minimally Invasive and Percutaneous Fixation

In selected fractures, the surgeon can insert plates, screws, or nails through small incisions, guided by live X-ray imaging (fluoroscopy). This is called minimally invasive plate osteosynthesis (MIPO) or percutaneous fixation. The advantages include smaller scars, less disturbance to the soft tissues around the bone, and potentially faster healing of the surrounding tissue. Not every fracture is suitable for this approach — it depends on the pattern of the break and whether the fragments can be repositioned without direct exposure.

Computer-Assisted and Robotic Techniques

Some centres use computer navigation or robotic assistance, especially for pelvic, spinal, or complex peri-articular fractures. These tools help the surgeon place screws and implants with greater precision. The underlying principles of fixation are the same; the technology is an aid to accuracy.

Specialised Approaches by Body Region

Some fractures are managed with techniques specific to their location:

• Hip fractures are commonly treated with dynamic hip screws, cephalomedullary nails, or partial/total hip replacement, depending on the type and location of the break.
• Spinal fractures may be stabilised with pedicle screws and rods, or with minimally invasive cement injection (kyphoplasty or vertebroplasty) for certain compression fractures.
• Pelvic fractures often require a combination of external and internal fixation depending on stability.

The choice of approach is guided by the fracture pattern, the surgeon’s experience, and the resources of the operating centre.

Preparing for Fracture Fixation Surgery

Preparation depends on whether the surgery is being done urgently (after a recent injury) or in a planned way (for example, for a fracture that has not healed properly or for hardware removal).

In an urgent setting, much of the preparation happens quickly in hospital. The team will:

• Take a detailed history of the injury and your medical background
• Examine the injured limb, checking for nerve and blood vessel injury and for skin damage
• Order X-rays, and often CT scans for complex fractures or those involving joints; MRI may be used to assess soft tissue or spinal cord injury
• Run blood tests, an ECG, and other checks as needed for anaesthesia
• Give pain relief and, if needed, place the limb in a temporary splint or traction
• Treat any open wound with cleaning and antibiotics
• Stop blood-thinning medications where it is safe to do so, in discussion with the prescribing doctor
• Ask you to fast (usually no food for six hours and clear fluids stopped two hours before surgery)

For planned surgery, there is more time to optimise your overall health: controlling diabetes, treating infections, improving nutrition, stopping smoking, and reviewing all medications. Smoking is particularly important because it significantly slows bone healing and increases the risk of non-union and infection. Many surgeons strongly advise stopping smoking before and after fixation surgery.

You will meet the anaesthetist before the operation to discuss whether you will have general anaesthesia (you are fully asleep), regional anaesthesia (a nerve block or spinal/epidural injection that numbs the limb), or a combination. The choice depends on the body part, your health, and surgeon and anaesthetist preference.

What Happens During the Operation

1. Incision. The surgeon makes a cut over the fracture site, or a series of smaller cuts for minimally invasive approaches.
2. Exposure and cleaning. Damaged tissue and any contamination are removed. In open fractures, careful wound cleaning is critical.
3. Reduction. The bone fragments are repositioned into the correct alignment. This may be done by direct manipulation under view, or indirectly under X-ray guidance.
4. Fixation. Plates, screws, nails, pins, or wires are placed to hold the fragments stable.
5. Confirmation. Live X-ray (fluoroscopy) is used during and after fixation to confirm that the bones are correctly aligned and the hardware is in good position.
6. Closure. The wound is closed in layers with sutures or staples. A dressing and sometimes a splint are applied.

For external fixation, pins are drilled into the bone above and below the fracture and connected to an external frame, often without opening the fracture site itself.

Operating times vary widely — a simple wrist plate may take under an hour, while a complex pelvic or multi-fragment fracture can take several hours. The surgical team will give you an estimate based on the fracture.

Recovery and Healing

In Hospital

The hospital stay can range from one night (for example, after wrist or ankle fixation) to several days or longer for major fractures of the hip, pelvis, or femur. During this time the team will:

• Manage pain with a combination of medications
• Check the wound and watch for signs of infection or swelling
• Monitor circulation and nerve function in the limb
• Give blood thinners or pressure stockings to reduce the risk of deep vein thrombosis (a blood clot in a deep vein, usually in the leg)
• Start early movement and physiotherapy, often on the same or next day
• Teach you how to use crutches, a walker, or a wheelchair if you cannot put weight on the limb

The First Six Weeks

The early weeks are about protecting the fixation, controlling swelling, and beginning to move safely. Depending on the fracture and the type of fixation, the surgeon will advise:

• How much weight, if any, can be placed on the limb
• Whether a cast, brace, or sling is needed in addition to the hardware
• What exercises to start, and when
• When to return for wound checks and X-rays

Stitches or staples are usually removed at around two weeks. Swelling and bruising are normal and gradually improve. Many patients still feel quite tired during this phase.

Six Weeks to Three Months

Bone healing becomes visible on X-rays during this phase. Physiotherapy intensifies, with a focus on regaining range of motion, strength, and confidence. Weight-bearing is often gradually increased. People with desk-based work may return to work earlier, while those with physically demanding jobs usually need longer.

Three to Twelve Months

Most fractures take three to six months to heal solidly, although large bones or complex injuries can take a year or more. Strength, balance, and full function continue to improve well beyond the point at which the bone has united. Returning to sport or heavy physical activity is usually staged and guided by the surgical and physiotherapy team.

Some patients are surprised that recovery is slower than they expected. Bone healing follows biology, not willpower, and patience is part of the process.

Rehabilitation and Physiotherapy

Physiotherapy is a central part of recovery after fracture fixation. It helps prevent stiffness, rebuild muscle that has wasted during immobilisation, restore balance, and return the limb to useful function. A typical rehabilitation programme includes:

• Gentle range-of-motion exercises in the early weeks
• Gradually progressive strengthening as healing allows
• Training in safe walking patterns and use of walking aids
• Balance and proprioception (joint position sense) exercises
• Sport-specific or work-specific training in later phases

Following the physiotherapist’s instructions on weight-bearing and exercise is one of the most important things a patient can do to support a good outcome.

Risks and Complications

Fracture fixation surgery is generally safe and effective, but like any major operation it carries risks. These should be discussed with your surgeon before the operation. They include:

• Infection. Surface or deeper wound infections can occur. Deep infections around the hardware can be serious and sometimes require further surgery or removal of the implants.
• Bleeding and bruising. Some bleeding is expected; large blood loss is uncommon but possible in major fractures.
• Blood clots. Deep vein thrombosis and pulmonary embolism (a clot that travels to the lungs) are recognised risks, especially after lower limb or pelvic surgery. Preventive measures are routine.
• Delayed union or non-union. The bone may heal slowly or fail to heal, which can require additional surgery, bone grafting, or different hardware.
• Malunion. The bone may heal in a slightly incorrect position, which can cause stiffness, weakness, or arthritis.
• Hardware-related problems. Plates and screws can sometimes be felt under the skin, cause irritation, or rarely break. Loosening can occur if the bone does not heal as expected.
• Nerve or blood vessel injury. Nerves close to the fracture or surgical approach can be bruised or, rarely, damaged. Most nerve injuries improve over time.
• Stiffness of nearby joints. Especially after fractures near a joint or with prolonged immobilisation.
• Complex regional pain syndrome. An uncommon condition in which pain, swelling, and sensitivity persist long after the injury and need specialist management.
• Compartment syndrome. Severe swelling inside a limb that cuts off blood supply. This is an emergency and may require urgent surgery to release the pressure.
• Anaesthesia-related complications. Discussed with the anaesthetist beforehand.
• Fat embolism. Rare but possible after fractures of the long bones, especially the femur.

The overall risk of serious complications is low for most fractures, but it is higher in older patients, in those with multiple injuries, in open fractures, and in patients with conditions such as diabetes, smoking, or poor circulation.

Life After Fracture Fixation Surgery

The Implants

Modern fracture fixation implants are designed to remain in the body for life. For most patients, hardware does not need to be removed once the bone has healed. Removal may be considered if the implants cause persistent pain, irritate skin or tendons, become infected, or if the patient is young and the hardware sits in a prominent position. Removal is a separate operation with its own risks.

Metal implants do not normally set off airport security at typical levels, but you can ask your surgeon for a card or letter describing your implant for travel purposes. MRI scans are generally safe with modern orthopaedic implants, but it is sensible to tell the radiology team about your hardware before any scan.

Bone Health for the Long Term

After a fracture, looking after bone health helps reduce the risk of future breaks and supports healing. General measures that are widely recommended include:

• Eating a balanced diet with enough calcium and protein
• Maintaining adequate vitamin D levels
• Doing regular weight-bearing exercise once your surgeon allows it
• Avoiding smoking and limiting alcohol
• Investigating and treating osteoporosis if it is suspected, especially in older adults after a fragility fracture

Return to Work, Driving, and Sport

When you can return to driving, work, and sport depends on the bone involved and how well healing is going. As a general guide:

• Office work may be possible within a few weeks if you can travel safely.
• Driving is usually allowed once you can perform an emergency stop comfortably and are off strong pain medication — often six weeks or more for lower limb fractures.
• Physical work and contact sports usually need three to six months or longer, and clearance from the surgical team.

These are general patterns; the surgeon’s individual advice always takes priority.

Fracture Fixation Surgery in Children

Children’s bones are different from adult bones in important ways, and this affects how fractures are treated. Children’s bones heal faster, they have a remarkable ability to remodel small deformities as they grow, and they contain growth plates (the cartilage zones at the ends of long bones that allow bones to lengthen). These differences mean:

• Many paediatric fractures that would need surgery in adults can be treated successfully in a cast.
• Fractures involving the growth plate need careful evaluation, because injury to a growth plate can affect future bone growth.
• When surgery is needed, paediatric orthopaedic surgeons often use techniques that avoid crossing the growth plate or use thinner, more flexible hardware.

Common approaches in children include:

• Flexible intramedullary nails (titanium elastic nails) for fractures of the femur and forearm. These are inserted away from the growth plates and removed once healing is complete.
• K-wires for many wrist, elbow (especially supracondylar humerus fractures), and hand fractures. They are usually removed in clinic a few weeks later.
• External fixation for open fractures or polytrauma.
• Plates and screws in older children and adolescents, particularly when the growth plates are closing.

Recovery in children is often faster than in adults, but rehabilitation, supervision of weight-bearing, and follow-up are still important. Parents should expect close monitoring with X-rays to confirm healing and, in growth plate injuries, to check that the bone is growing normally.

Frequently Asked Questions

How do I know if my fracture needs surgery?

This is a clinical decision made by your orthopaedic surgeon based on the X-rays (and sometimes CT or MRI), the bone involved, how much the fragments are displaced, whether a joint is affected, and your overall health. Many fractures heal well in a cast; others need fixation to heal in the correct position.

Will I be awake during the surgery?

That depends on the type of anaesthesia. General anaesthesia puts you fully to sleep. Regional anaesthesia (such as a spinal block for hip surgery, or a nerve block for arm surgery) numbs the area while you remain awake or lightly sedated. The anaesthetist will discuss the options with you.

Is the surgery painful?

You will not feel pain during the operation itself. Afterwards, there is usually significant discomfort for the first few days, which is managed with pain medications, ice, and elevation of the limb. Pain typically improves steadily over the following weeks.

How long will it take to heal?

Most fractures unite over three to six months, but full functional recovery often takes longer. Large bones, complex fractures, and injuries in older adults or smokers can take a year or more. Your surgeon will follow your healing with X-rays.

Will I need the metal implants removed later?

Usually not. Modern implants are designed to remain in place. Removal is considered if the hardware causes pain, irritation, or infection, or sometimes in young, active patients. Pins and external fixators are removed once their job is done.

Will I set off metal detectors at the airport?

Modern airport scanners are generally not triggered by orthopaedic implants. A doctor’s letter describing your hardware can help if there are questions during security checks.

Can I have an MRI scan with metal implants?

Most modern orthopaedic implants are MRI-compatible, though they can cause some distortion of the images near the implant. Always tell the radiology team about your surgery and any hardware before an MRI.

What happens if the bone does not heal?

If a fracture heals very slowly (delayed union) or fails to heal (non-union), further treatment may be needed. Options include bone stimulators, bone grafting, changing the type of fixation, or surgery to remove infected hardware. Non-union is uncommon for most fractures but more likely in certain bones, in smokers, and in patients with poor bone quality.

When can I bear weight on the limb?

This varies widely. After some fractures (for example, intramedullary nailing of the tibia or hip fractures in older adults), weight-bearing is allowed almost immediately. After others, you may need to keep weight off for six weeks or longer. Always follow your surgeon’s specific instructions, as bearing weight too early can disrupt the fixation.

Will my limb ever feel completely normal again?

Many patients return to full or near-full function, especially after well-aligned fractures away from joints. Some are left with a slight loss of motion, occasional stiffness, mild aching in cold weather, or a visible scar. Fractures that extend into joints carry a higher risk of long-term stiffness or arthritis. A good rehabilitation programme makes a meaningful difference to the final outcome.

Conclusion

Fracture fixation surgery is a well-established operation that helps broken bones heal in the correct position, restores limb function, and reduces the risk of long-term deformity. The choice between internal fixation, external fixation, and minimally invasive approaches depends on the specific bone, fracture pattern, soft tissue condition, and the patient as a whole. Recovery unfolds over months rather than weeks and depends as much on rehabilitation and bone health as on the surgery itself.

Understanding the goals of the operation, what the recovery looks like, and what to watch for along the way can help you take an active role in your healing. Detailed decisions about the type of fixation, the timing of weight-bearing, and the pace of rehabilitation are best made together with your orthopaedic surgeon and physiotherapy team, who can tailor the plan to your specific fracture and circumstances.
