Complete Guide to Broken Ankle Bones

What is an Ankle Fracture?

An ankle fracture is when one bone or multiple bones making up the ankle joint are broken. These bones include:

• Tibia (shinbone) – This is the larger bone of the lower leg.
• Fibula – this is the smaller bone which is on the outside of the lower leg.
• Talus – this is the bone that sits between the heel bone and the tibia/fibula.

An ankle fracture can range from a small crack in one bone to multiple broken bones that cause the ankle to become unstable or misaligned. Fractures are typically caused by twisting injuries, falls, or high-impact trauma such as sports injuries or motor vehicle accidents.

Because the ankle is a weight-bearing joint, any fracture to this area can significantly affect mobility and requires proper assessment and treatment.

What are the Types of Ankle Fractures?

Doctors classify ankle fractures based on the location and number of bones broken.

Common types of ankle fractures that are diagnosed are:

• Lateral malleolus fracture: A break of the fibula on the outside of the ankle. This is the most common type of ankle fracture.
• Medial malleolus fracture: A break of the tibia on the inner side of the ankle.
• Bimalleolar fracture: Involves both the lateral and medial malleoli. This type of fracture typically causes more instability in the ankle.
• Trimalleolar fracture: This fracture involves all three parts of the ankle—lateral malleolus, medial malleolus, and the back of the tibia (posterior malleolus). These are often more severe and may require surgery.
• Maisonneuve fracture: A fracture higher up the fibula, associated with an ankle injury and often overlooked without proper imaging.
• Pilon fracture: A fracture of the bottom of the tibia where it joins the ankle. This is a more serious injury often caused by a high-energy impact.

Each type varies in severity and treatment depending on how much the bones have moved out of place (displacement) and whether the surrounding ligaments are also damaged.

How Common are Ankle Fractures?

Ankle fractures are among the most frequently seen fractures in emergency departments and orthopaedic clinics, such as Access Ortho.

• Incidence: In Australia, ankle fractures are a very common orthopaedic injury. Some estimate around 150–200 ankle fracture cases are seen per 100,000 people each year.
• Demographics:
  • Younger adults often get ankle fractures when they play sports or due to high-energy trauma.
  • Older adults, especially women, are more prone to ankle fractures due to falls and underlying osteoporosis.
• Gender differences:
  • Men under 50 are the most commonly affected group.
  • Women over 50 are at increased risk, due to bone density loss.

Ankle fractures are more common in winter due to slippery conditions, and are a common injury in sports like netball, basketball, and football.

Symptoms and Causes

What Causes Ankle Fractures?

Excessive force applied to the ankle joint beyond what the bones and ligaments can withstand often leads to ankle fractures. Common causes include:

• Twisting injuries – such as rolling the ankle awkwardly while walking or during sport.
• Falls – especially from a height or onto an uneven surface.
• Sports injuries – especially in high-impact or pivot-heavy sports like netball, basketball, soccer, and rugby.
• Motor vehicle accidents – due to sudden high-force impact or crush injuries.
• Direct blows – such as being hit by a heavy object.

These injuries can lead to isolated bone breaks or complex fractures involving multiple parts of the ankle joint.

What are Ankle Fracture Risk Factors?

There are a number of factors that can increase the chance of sustaining an ankle fracture.

• Age: Bone density in most people decreases with age, especially in post-menopausal women, increasing fracture risk.
• Osteoporosis: Weakened bones caused by osteoporosis are more susceptible to breaks, even from minor trauma.
• Previous ankle injuries: A history of repeated sprains or fractures can cause greater instability and, therefore, a higher chance of reinjury.
• Participation in high-risk sports: Activities involving jumping, cutting, pivoting, or rapid direction changes increase risk.
• Poor footwear: Inadequate ankle support can contribute to rolling or twisting injuries.
• Uneven surfaces: Walking or running on unstable ground can increase the likelihood of falls and missteps.

What are the Symptoms of Ankle Fractures?

The symptoms experienced when you have an ankle fracture will vary depending on the fracture. Common symptoms include:

• Sudden, severe pain in the ankle or lower leg at the time of injury
• Swelling and bruising around the ankle
• Difficulty or inability to bear weight
• Deformity – the ankle may look out of alignment or visibly twisted
• Tenderness to touch over the bones (as per the Ottawa Ankle Rules)
• Instability – feeling like the ankle will “give out” when trying to stand

Pain may increase with movement, and in some cases, there may be numbness or tingling if nerves are affected.

What are the Complications of Ankle Fractures?

If not managed appropriately, ankle fractures can lead to both short and long-term complications. These may include:

• Post-traumatic arthritis: Damage to the joint surface can lead to arthritis, especially in cases involving joint displacement or intra-articular fractures. This may occur gradually, with symptoms sometimes appearing years later.
• Malunion or nonunion: If the bones do not heal in the correct position or fail to heal at all, this may result in long-term pain and functional problems.
• Chronic instability: Damage to the surrounding ligaments and joint capsule can lead to a persistently unstable ankle, increasing the risk of future injuries.
• Stiffness and reduced range of motion: Particularly if immobilisation is prolonged or rehab is incomplete.
• Infection: A risk in open fractures or following surgery.
• Nerve or blood vessel damage: Although rare, this can occur, especially in high-impact injuries.

Early diagnosis and management help minimise the risk of complications and support optimal recovery. Access Ortho, located in Ipswich and Brisbane, is a dedicated fracture clinic providing urgent orthopaedic care for ankle injuries.

Diagnosis and Tests

How are Ankle Fractures Diagnosed?

Diagnosing an ankle fracture begins with a clinical assessment by a healthcare professional.

• History: Your provider will ask how the injury occurred (e.g., fall, twist, direct blow) to understand the mechanism and assess the likelihood of a fracture.
• Physical Examination: The injured ankle is checked for:
  • Swelling and bruising
  • Bone tenderness over specific areas
  • Deformity or joint misalignment
  • Inability to bear weight
• The provider may also examine areas above and below the ankle (like the base of the fifth metatarsal, the proximal fibula, or the talus) to rule out associated injuries.

Which Tests do Providers Use to Diagnose Ankle Fractures?

The main imaging tests used include:

• X-rays: The first and most important tool for diagnosing an ankle fracture. A standard ankle series includes:
  • AP (Anteroposterior) view
  • Lateral view
  • Mortise view – which gives a better view of the joint space

X-rays help determine if the fracture is:

• Present
  • Displaced or non-displaced
  • Involving the joint surface
  • Stable or unstable
• Weight-bearing X-rays: Used when possible to assess whether the ankle joint remains aligned under pressure — an important tool for evaluating stability.
• CT scans: May be requested to better understand:
  • Fractures of the posterior malleolus
  • Comminuted (shattered) fractures
  • Fractures that extend into the joint
  • Situations where weight-bearing films cannot be obtained but there is concern about stability
• MRI scans: Less commonly used in the acute setting but may be helpful for:
  • Assessing ligament injuries or tendon damage
  • Suspected talar dome lesions
  • Syndesmotic injuries (see below)

Specific Considerations for Ankle Fracture Diagnosis

• Ottawa Ankle Rules: A clinical tool used to determine whether imaging is needed after an ankle injury. X-rays are recommended if there is:
  • Bone tenderness along the back edge or tip of the lateral or medial malleolus, or
  • Inability to bear weight at the time of the injury and on assessment in the clinic
• Syndesmotic Injury Assessment:
  • The syndesmosis is the ligamentous structure between the tibia and fibula that stabilises the ankle.
  • Suspected injuries here may be confirmed through:
    • Stress X-rays
    • CT or MRI
  • Syndesmotic injuries often occur with posterior malleolus fractures and usually indicate an unstable fracture pattern requiring surgical assessment.

Ankle Fracture Classification Systems

Fractures are classified to guide treatment decisions. The most commonly used systems include:

• Weber Classification (based on the level of fibula fracture relative to the syndesmosis):
  • Type A – fracture below the syndesmosis (usually stable)
  • Type B – fracture at the level of the syndesmosis (variable stability)
  • Type C – fracture above the syndesmosis (often unstable, likely requiring surgery)
• Lauge-Hansen Classification: Based on the position of the foot and the direction of force during injury (e.g., supination-external rotation). Mainly used in specialist settings.
• AO/OTA Classification: A comprehensive system used by orthopaedic surgeons, combining fracture location and pattern

These systems help determine whether the fracture is stable or unstable, influencing whether surgery is needed. The medical team at Access Ortho is skilled in the assessment, diagnosis, and care of orthopaedic injuries.

Management and Treatment

How are Ankle Fractures Treated?

How ankle fractures are treated depends on several key factors:

• Which bones are broken
• Whether the fracture is stable or unstable
• How much the bones have moved out of place (displacement)
• Whether the joint surface is involved
• Patient age, activity level, and overall health

Treatment falls into two main categories: non-surgical (conservative) and surgical management. The goal is always to ensure the ankle heals in proper alignment and regains strength and function. The orthopaedic team at Access Ortho will guide you on the most appropriate care for your injury.

Non-Surgical Treatment for Ankle Fractures

Stable ankle fractures that remain well aligned can often be treated without surgery. Non-surgical options may include:

• Moon boots (CAM boots) or plaster casts: These provide support and protection while the bone heals.
• Immobilisation: The ankle may be immobilised for several weeks depending on the fracture type and symptoms.
• Weight-bearing status:
  • Patients with stable fractures may begin weight-bearing as tolerated.
  • Some may need to remain non-weight-bearing for 1–3 weeks, particularly early on.
• Follow-up X-rays: Typically done 10–14 days after injury to confirm the fracture hasn’t moved.
• Gradual return to mobility: Most patients begin transitioning out of the boot by 6 weeks and start gentle movement and strengthening thereafter.

Surgical Treatment for Ankle Fractures

Surgery is usually required for unstable or displaced fractures or when joint alignment cannot be restored with conservative treatment. Common surgical procedures include:

• Open Reduction and Internal Fixation: This is the most common surgical approach. Bones are repositioned (reduced) and held in place with screws, plates, or rods.
• External fixation: This is used in cases with severe swelling or complex injuries. A stabilising frame is placed outside the body and connected to pins in the bones.
• Arthroscopy-assisted reduction: In select cases, a small camera is inserted into the joint to help guide repair and assess damage inside the ankle.

Surgery aims to restore joint alignment, ensure stability, and decrease long-term complications like arthritis. The orthopaedic team will help arrange surgery if this is required.  

Ankle Fracture Recovery and Rehabilitation

Recovery from an ankle fracture varies depending on the severity of the injury and the treatment approach. 

• Initial rest and protection: The First few weeks focus on reducing swelling and protecting the healing bone.
• Range of motion exercises: Begin once immobilisation is reduced. Helps prevent stiffness.
• Strengthening and proprioception training: Restores muscle strength, balance, and coordination. Often guided by a physiotherapist.
• Return to full activity: Most patients regain functional mobility within 3–6 months. Full recovery and return to sports may take up to 9–12 months.

Patients should be aware that some swelling can persist for many months, and continued rehab may be needed to regain pre-injury function.

Prevention

How Can I Prevent Ankle Fractures?

While not all ankle fractures can be prevented, there are several strategies that can reduce your risk:

• Wear appropriate footwear: Supportive shoes with good grip can reduce the risk of rolling or twisting your ankle, especially on uneven terrain.
• Strengthen your ankles: Exercises targeting the calf muscles, foot muscles, and ankle stabilisers help improve joint strength and support.
• Improve balance and coordination: Proprioception training, like practising standing on one leg or a balance board, helps prevent missteps.
• Warm up before activity: Gentle stretching and mobility exercises help warm-up your muscles and joints for movement.
• Be cautious on slippery or uneven surfaces: Take extra care in wet or icy conditions.
• Treat previous injuries properly: Fully rehabilitate ankle sprains or instability to prevent reinjury.

Ankle Fracture Prevention in Sports

Athletes, particularly in high-risk sports like netball, basketball, soccer, and trail running, should take extra precautions:

• Use ankle braces or tape: Especially helpful for individuals with a history of sprains or instability.
• Strengthen lateral ankle muscles: Specific exercises can help protect against twisting injuries.
• Incorporate agility and landing drills: Teaches proper body mechanics and reduces risky foot positions during jumping and cutting movements.
• Coach-supervised training: Proper technique reduces the risk of dangerous movements or awkward landings.
• Rest and recovery: Avoid training through fatigue, as tired muscles increase injury risk.

Outlook / Prognosis

What To Expect If I Have an Ankle Fracture?

Most ankle fractures heal well with appropriate treatment. Your outcome depends on:

• The type and severity of the fracture
• Whether the joint was involved
• Stability of the fracture
• Your overall health, age, and bone strength
• How closely you follow your rehabilitation plan

Stable fractures usually heal with minimal long-term impact, while more complex or displaced fractures may take longer and require surgery.

What Is the Recovery Time from an Ankle Fracture?

Recovery timelines vary, but general guidelines are:

• Stable fractures (non-surgical): May take 6–8 weeks for the bone to heal, with gradual return to full activity over 3–4 months.
• Surgical fractures: Bone healing still takes around 6–8 weeks, but full recovery and return to sport or high-level activity may take 6–12 months.
• Swelling and stiffness: Often persist for several months after healing begins.

Long-term Outcomes of Ankle Fractures

Most people regain normal function after an ankle fracture, especially with early rehab and follow-up care. Long-term outcomes may include:

• Return to sport or work: Most patients return to their pre-injury activities, but high-level athletes may require longer rehabilitation.
• Mild lingering symptoms: Occasional discomfort, swelling, or stiffness may persist, especially after prolonged standing or intense activity.
• Complications in some cases:
  • Post-traumatic arthritis – more common with joint surface fractures or improper alignment
  • Chronic instability – if ligaments were injured or healing is incomplete
  • Reduced range of motion – if scar tissue develops or rehab is delayed

With proper care, most ankle fractures heal well, and patients return to an active, pain-free lifestyle.

 Access Ortho is a private fracture clinic in Brisbane and Ipswich that offers urgent care for fractures, sprains and strains.

When to Seek Medical Care

When Should I Go to a Fracture Clinic for an Ankle Fracture?

You should attend a fracture clinic if:

• You have been diagnosed with an ankle fracture or have a strong suspicion of one (e.g. can’t bear weight, swelling, bruising, or pain after a twist/fall).
• Emergency care has confirmed a fracture, and you’ve been advised to follow up.
• You’re experiencing worsening symptoms, even after an initial diagnosis (increased pain, instability, or difficulty walking).
• Your GP or emergency doctor has referred you for orthopaedic follow-up.

Fracture clinics provide ongoing assessment, imaging, and management to ensure your fracture heals correctly. This is particularly important for preventing long-term complications like arthritis or ankle instability.

What is a Fracture Clinic?

A fracture clinic is a specialist service where orthopaedic and musculoskeletal experts assess and treat broken bones and acute joint injuries. These clinics:

• Review imaging (e.g. X-rays, CT scans)
• Assess the stability of the fracture
• Determine if surgery or conservative treatment is needed
• Guide your recovery with clear instructions
• Arrange follow-up imaging and review appointments
• Connect you with rehabilitation providers such as physiotherapists

Fracture clinics are ideal for managing non-life-threatening fractures that still require expert care and follow-up — especially injuries to the ankle, wrist, hand, foot, or shoulder.

Emergency Signs with Ankle Fractures

Seek urgent emergency care (not just a fracture clinic) if you have:

• Open fractures (bone breaking through the skin)
• Severe deformity of the ankle or foot
• Coldness, numbness, or loss of pulses in the foot or toes — signs of vascular compromise
• Excessive swelling or pain unrelieved by rest or elevation
• Signs of infection (fever, warmth, redness at injury site if already in a cast)

These red flags may indicate the need for immediate intervention to avoid permanent damage.

Special Considerations

Ankle Fractures in Children and Adolescents

Children and teens can experience ankle fractures that affect the growth plate (physis). The physis is the area of developing tissue near the ends of long bones. Growth plate injuries require careful assessment to avoid long-term complications such as growth issues or joint deformity.

Common in this age group are Salter-Harris fractures, classified as:

• Type I–V, depending on how the growth plate and surrounding bone are involved.
• Depending on fracture type and displacement, treatment may range from casting to surgical fixation.

Regular follow-up is important to monitor growth plate function and ensure the ankle develops normally.

Ankle Fractures in Elderly Patients

Older adults are more vulnerable to ankle fractures due to:

• Reduced bone density (osteoporosis)
• Balance issues and falls
• Slower healing capacity

Fractures in this group often result from low-energy trauma, such as a fall from standing. Management may be complicated by coexisting medical conditions, so treatment must balance fracture healing with mobility and independence.

Prevention strategies post-injury should include:

• Fall prevention programs
• Home safety assessments
• Bone health screening and treatment

Diabetic Ankle Fractures

People with type 2 diabetes face unique challenges in fracture care, including:

• Delayed healing due to poor blood flow
• Higher risk of infection
• Neuropathy, which can reduce pain sensitivity and mask injury severity

A major concern is Charcot foot, a serious condition in which nerve damage leads to bone weakening and joint collapse — often triggered by unnoticed or poorly managed fractures.

Diabetic patients with ankle fractures require:

• Prompt diagnosis
• Strict offloading (non-weight bearing)
• Close follow-up to prevent complications

Living with an Ankle Fracture

Ankle Fracture and Daily Activities

During the healing phase, you may need to adapt your daily routine. Tips include:

• Use of mobility aids such as crutches, knee scooters, or walking frames
• Home modifications like shower chairs, handrails, and removing trip hazards
• Planning – allow extra time for dressing, showering, and commuting
• Elevating the leg regularly to reduce swelling and improve comfort

Occupational therapists can assist with practical solutions for independence during recovery.

Returning to Work after Ankle Fracture

When you return to work depends on:

• The type and severity of your fracture
• Whether you had surgery
• The physical demands of your job

Guidelines:

• Desk-based jobs: Return in 1–3 weeks, possibly with mobility support
• Manual labour roles: May require 8–12+ weeks and medical clearance
• Your doctor or orthopaedic provider can give specific advice on light duties, phased return, or workplace modifications.

Sports and Exercise after Ankle Fracture

Returning to sport is possible after an ankle fracture, but must be gradual and supervised.

A typical recovery plan includes:

• Physiotherapy for strength, balance, and range of motion
• Sport-specific drills are introduced after bone healing is confirmed
• Clearance from your provider before resuming high-impact or contact sports

Timelines vary:

• Low-impact exercise (e.g. swimming, cycling) may resume in 2–3 months
• High-impact sports (e.g. netball, football) may take 4–6+ months

Expect some stiffness or weakness initially, but most athletes can return to performance levels with the right rehab.

Commonly Asked Questions about Ankle Fractures

How do I know if my ankle is fractured or sprained?

A sprain affects the ligaments, while a fracture involves broken bone. Both may cause swelling, pain, and bruising, but fractures often involve:

• Inability to bear weight
• Visible deformity or misalignment
• Localised bone tenderness

 If you’re unsure, it’s best to seek medical assessment. An X-ray is the only way to confirm a fracture.
You can also get a Virtual Ankle Fracture consultation

Can you walk on a fractured ankle?

Some people can walk on a minor fracture, especially if it’s non-displaced, but this doesn’t mean it’s not broken. Most fractures require reduced weight-bearing or crutches. Walking on an unstable or misaligned fracture can worsen the injury.

How long does an ankle fracture take to heal?

Most ankle fractures take:

• 6–8 weeks for the bone to heal
• 3–6 months for full function to return
• Up to 12 months for swelling or stiffness to completely settle
• Surgical cases may take longer. Individual recovery depends on age, general health, and rehabilitation.

Will I need surgery for my ankle fracture?

Surgery is often needed if:

• The fracture is unstable or displaced
• Multiple bones or the joint surface are involved
• There’s damage to ligaments or the syndesmosis
• Stable, well-aligned fractures are typically managed without surgery.

What are the long-term effects of an ankle fracture?

Some people make a full recovery, while others may experience:

• Stiffness or swelling
• Post-traumatic arthritis
• Chronic instability if ligaments were also injured
• Rehabilitation reduces the risk of long-term issues.

Can an ankle fracture heal without a cast?

Some fractures can be treated with a walking boot (moon boot) instead of a plaster cast. This depends on the fracture type, stability, and whether weight-bearing is allowed. The team at Access Ortho will guide you.

How painful is an ankle fracture?

Pain is typically moderate to severe at the time of injury. It usually improves with:

• Rest, elevation, and ice
• Pain medications like paracetamol or anti-inflammatories

Pain should steadily improve over the first 1–2 weeks.

Will I develop arthritis after an ankle fracture?

Post-traumatic arthritis is a potential long-term complication, especially:

• After joint surface fractures
• If the bones don’t heal in alignment

 Maintaining proper joint position during healing reduces this risk.

Can I drive with an ankle fracture?

Driving is not allowed if:

• You are wearing a boot or cast on your right (driving) foot
• You are not able to safely perform an emergency brake

Most people can resume driving once they can fully weight-bear without a boot and have regained strength and control. Always check with your doctor and insurer.

What exercises can I do with a fractured ankle?

During recovery:

• Early phase: Toe curls, gentle range-of-motion (if allowed)
• Mid-phase: Light resistance exercises, cycling
• Late phase: Balance, agility, and sport-specific drills

Only exercise within limits advised by your doctor or physiotherapist.

How do I know if my ankle fracture is healing properly?

Signs of proper healing:

• Steady improvement in pain and function
• Follow-up X-rays show bone healing
• Decreasing swelling and bruising

Warning signs include persistent pain, new deformity, or numbness. Always attend scheduled reviews.

Can ankle fractures recur in the same location?

Reinjury is possible, particularly if:

• The bone healed in poor alignment
• Ligaments are still weak
• You return to sport too quickly

Strengthening and proper rehab help prevent recurrence.

What is the difference between a high ankle sprain and an ankle fracture?

A high ankle sprain (syndesmotic injury) affects the ligaments between the tibia and fibula. It can mimic a fracture and may occur with or without one. Diagnosis is made via X-rays or MRI. Management often takes longer than a regular sprain.

Will I need physiotherapy after an ankle fracture?

Physiotherapy is a key part of recovery. It helps:

• Regain range of motion
• Rebuild strength and balance
• Restore normal walking and activity

Most people start rehab once the bone has healed or the boot is removed.

Can I prevent future ankle fractures?

Future ankle fractures can be prevented by:

• Ankle strengthening exercises
• Proper footwear for your activity
• Balance training
• Avoiding uneven or slippery surfaces

 If you’ve had a fracture before, supportive braces may help during sport.

What shoes should I wear after an ankle fracture?

During healing, you may be treated in a moon boot.

After initial recovery, shoes that offer firm heel support, are non-slip, and fit well are best. You can gradually transition to less supportive footwear over time.

When can I return to sports after an ankle fracture?

Return-to-sport depends on:

• Bone healing (confirmed by imaging)
• Strength and balance testing
• Clearance from your doctor or physio
• The style of sport involved, impact level, duration, etc.
