Ankle fracture
The incident of a broken ankle involves a fracture of one or more bones (such as the tibia, the fibula, and the talus) and is characterized by intense pain, swelling, and visible deformity. In the case of such trauma, prompt management is essential to preserve the integrity of the joint.
Definition and anatomy of ankle fracture
An ankle fracture refers to the partial or complete breakage of the bones that form this complex joint. The ankle mainly consists of the tibia, the fibula (formerly called the perone), and the talus. Understanding this bone structure helps distinguish between different types of fractures such as the simple malleolar fracture, the bimalleolar fracture, or the Maisonneuve fracture. Each of these injuries affects the mobility and stability of the joint differently.
Symptoms and risk factors
The signs of a fracture include:
- Severe acute pain,
- Swelling and inflammation,
- Visible ankle deformity,
- Inability to bear weight.
Additionally, certain factors increase the risk of fracture, including:
- Injuries from falls or twists,
- Engaging in intense sports activities,
- Bone fragility related to osteoporosis or advanced age.
Diagnosis and additional tests
The diagnosis is based on a complete clinical examination integrated with a detailed history of the trauma context. To confirm the presence and nature of the fracture, imaging tools such as X-ray, CT scan, or MRI are used. These examinations allow for an assessment of the joint's stability and help guide the treatment accurately.
The different types of fractures
Fractures affecting the lateral malleolus, medial malleolus, or both (so-called bimalleolar fracture). These are articular injuries, generally displaced, for which no displacement is tolerated. Treatment is based on osteosynthesis (anatomic reduction and fixation with screws or plate), which is systematically performed in case of displacement.
Trimalleolar fractures combine injuries of the lateral, medial, and posterior tibial malleolus: they are highly unstable and always require surgical management.
Pilon fractures involve the articular roof of the distal tibia. Common in high-energy trauma (falls, accidents), they can be comminuted and affect the weight-bearing surface of the joint.
Articular displacement is poorly tolerated: treatment is almost always surgical, except for perfectly non-displaced fractures.
These fractures carry a high risk of long-term ankle osteoarthritis.
Talus fractures include fractures of the neck, body, head or the posterior/lateral processes. Relatively rare (about 0.1% of all fractures), they usually result from high-energy trauma.
The blood supply to the talus is limited: displacement, associated dislocation or open fracture significantly increases the risk of avascular necrosis (up to 33% according to some series) and osteoarthritis.
- A displaced talar neck fracture requires urgent reduction, often surgical if closed reduction fails.
- Body or process fractures may also require fixation or, in highly comminuted cases, primary arthrodesis.
Often overlooked, these lesions compromise the stability of the malleolar mortise. Present in about 10% of ankle fractures, particularly in Weber B or C types, they must always be looked for.
Diagnosis may require weight-bearing x-rays, CT scan, or arthroscopy. If unstable, the syndesmosis is surgically repaired, sometimes under arthroscopy.
High fracture of the fibula, near the knee, associated with a tear of the syndesmosis and/or injury to the medial malleolus or deltoid ligament. It is due to a pronation-external rotation mechanism according to Lauge-Hansen.
Often missed if imaging is not done up to the knee. Management is surgical: reduction and fixation of the fibula, stabilization of the syndesmosis, repair of the malleolus or deltoid ligament.
The fracture line communicates with the exterior, exposing bone and soft tissues. The risk of infection and healing complications is high. Management includes:
- Intravenous antibiotics, urgent surgical debridement, irrigation, and bone stabilization according to Gustilo-Anderson.
- Bone stabilization is most often surgical, depending on contamination and tissue condition.
Associated with dislocation of the ankle, these indicate high-energy trauma, with significant skin and ligament injuries.
Especially in talus fractures, associated dislocation increases the risk of talus necrosis and later osteoarthritis.
Our treatment options and care offered
Conservative treatment of a stable ankle fracture relies on immobilizing the joint, generally using a cast, a splint, or a walking boot, with no weight bearing on the foot for about six weeks. This approach is suitable when bone alignment is maintained and the fracture remains undisplaced, such as in the case of an isolated malleolus fracture without injury to the medial ligament or instability of the syndesmosis.
Surgical Treatment
When an intervention is necessary, surgery allows the realignment of bone fragments. Our specialist, Doctor Schramm, uses arthroscopic and mini-invasive techniques to perform open reduction and internal fixation. These methods promote quick recovery and reduce the risk of complications.
Why Choose the Foot Clinic?
The Foot Clinic stands out for its expertise in orthopedic surgery and trauma surgery of the foot and ankle.

Our commitment is based on comprehensive support (diagnosis, treatment, follow-up, and rehabilitation) to optimize the recovery of the joint.
Rehabilitation, monitoring and prevention
Rehabilitation after an ankle fracture is essential to restore range of motion, strength, and balance. After immobilization (often 4 to 6 weeks), gentle mobility exercises (such as rotations or the ankle alphabet) are introduced as soon as weight-bearing is allowed, often between two and six weeks depending on the stability of the fracture. Gradually, strengthening exercises with elastic bands and partial weight-bearing are implemented, quickly supplemented by proprioception exercises (balancing on one leg, unstable board) to prevent recurrence.
From a medical follow-up perspective, X-rays are necessary during the first consultations to check for proper bone healing and to adjust the progression. Finally, prevention relies on proper warm-up before any activity, breaks during intense exertion, wearing well-fitted shoes, and continuing proprioception exercises to maintain alertness and joint stability in the long term.
FAQ
Complications such as joint stiffness, chronic instability, persistent pain, an ankle cyst or post-traumatic osteoarthritis can occur if bone alignment and stabilization are not optimal. Open fractures and cartilage injuries also increase the risk.
Yes, especially during immobilization. Preventive anticoagulation is often prescribed to prevent phlebitis or pulmonary embolism, especially if weight-bearing is forbidden or delayed.
Driving can generally resume when ankle mobility and strength allow for emergency braking without pain: on average, after 6 weeks post-fracture, subject to medical approval.
Start with mobility exercises such as the “ankle alphabet,” then strengthening exercises with an elastic band, quickly followed by proprioception (balancing on one leg, wobble board), and later on, functional or plyometric exercises depending on the patient's ability.
Yes: smoking, diabetes, certain conditions such as osteoporosis, or steroid treatments can delay bone healing and increase the risk of complications.
Edema can last up to a year after the fracture. It is advisable to elevate your foot, apply ice, gently massage the area, or exercise in water to limit discomfort.
