What are the treatment options for ankle fracture?

An ankle fracture can involve the lower ends of the leg bones or the outer ankle bone, and may affect one or more parts of the joint. X-rays and an examination help show alignment, stability and skin condition. A stable fracture that remains aligned may be protected in a cast or boot. Displacement, joint involvement, open injury or instability may require fixation.

A cast restricts movement while the bone heals; a walking boot can offer protection with easier access for checks when clinically suitable. Fixation surgery uses hardware to restore alignment and hold the fragments steady. Rehabilitation then works on swelling, ankle movement, strength, balance and a safe return to weight-bearing.

Keep weight off the injured ankle until you have clear instructions, elevate it, and protect the skin and swelling. Use crutches correctly and attend follow-up imaging or examinations. Do not remove a cast, alter a boot or drive while your clinician says the ankle is unsafe. After surgery or immobilisation, complete the prescribed rehabilitation and increase loading gradually.

Go to urgent care for an ankle that looks deformed, an open wound, exposed bone, severe swelling, uncontrolled pain, numbness, a pale or blue foot, or toes that cannot move. While in a cast or boot, increasing tightness, burning, loss of sensation, fever or new calf pain also needs prompt review.

Is the fracture stable and aligned? How long should I avoid weight-bearing? Would a cast, boot or fixation give the joint the right protection? When can ankle movement and rehabilitation begin?
