Ankle Fracture (Without Syndesmotic Injury)

This protocol applies to ankle fractures that do not involve the syndesmosis (the strong ligament complex connecting the two lower leg bones just above the ankle). Patients with diabetes may be kept non-weight-bearing longer — see your surgeon's specific instructions.

This page explains how a ankle fracture (without syndesmotic injury) is commonly managed, in plain language, based on Dr. Kee's typical approach to this injury.

Expected Bone Healing

Every fracture is different. Treatment varies based on the exact fracture pattern, displacement, age, whether surgery is needed, bone quality, other injuries, and how an individual heals. This page is general education, not your personal treatment plan — always follow the specific instructions given to you by Dr. Kee's office.

What Is This Injury?

This protocol applies to ankle fractures that do not involve the syndesmosis (the strong ligament complex connecting the two lower leg bones just above the ankle). Patients with diabetes may be kept non-weight-bearing longer — see your surgeon's specific instructions.

Bone Doc Tip

An ankle can be healed on X-ray before balance, calf strength, and confidence are fully restored.

How Is It Treated?

This fracture may be treated with or without surgery, depending on the specific fracture pattern, how much the bone has shifted (displacement), and your individual situation. Your surgeon will determine the best approach for you.

Brace, Cast, Splint, or Sling

A short-leg splint (SLS) for about 2 weeks, then transition to a CAM boot (controlled ankle motion boot).

Walking or Using the Injured Limb

No weight bearing (NWB) for about 2 weeks.

For a full explanation of what these weight-bearing terms mean, see our Weight-Bearing Guide.

When Does Motion Begin?

No resistance or strengthening (NRM) for about 6 weeks. Motion (ROM) may begin around 2 weeks once the skin has healed, as you transition to a CAM boot while weight-bearing restrictions continue.

Physical Therapy

Ankle motion, gait, balance, and strengthening after the protection phase; formal therapy if needed.

Follow-Up and Imaging

A 6–8 week X-ray to confirm healing and clear the weight-bearing restriction. An optional 3–6 month X-ray may be used to monitor final healing.

Recovery Timeline
Short AnswerRecovery generally moves through protection, motion, weight-bearing, strengthening, and return to activity — at a pace your surgeon sets for your specific fracture.

Every fracture moves through the same general phases, though the exact timing is different for every patient:

1
Injury or Surgery
The fracture occurs, or is surgically stabilized if your surgeon recommends fixation.
2
Early Protection
A short-leg splint (SLS) for about 2 weeks, then transition to a CAM boot (controlled ankle motion boot).
3
Begin Motion
No resistance or strengthening (NRM) for about 6 weeks. Motion (ROM) may begin around 2 weeks once the skin has healed, as you transition to a CAM boot while weight-bearing restrictions continue.
4
Progress Use / Weight Bearing
No weight bearing (NWB) for about 2 weeks.
5
Strengthening
Physical therapy often helps rebuild strength once your surgeon confirms it's safe to begin.
6
Return to Activity
Return to work, school, driving, and sports is guided by your surgeon as healing progresses.
Return to Activity

Work or School: Desk work early; standing/manual work after comfortable gait and adequate healing.

Sports or High-Risk Activity: Usually 10–12 weeks or longer, after strength, balance, and impact tolerance return.

Watch For — Specific to This Injury

Loss of alignment, wound problems, calf pain, neurovascular symptoms, increasing swelling, or inability to progress.

General Warning Signs — When to Call

  • Increasing pain that isn't controlled by your prescribed plan
  • New numbness or weakness
  • Fingers or toes that become pale, blue, cold, or very swollen
  • A cast or splint that becomes excessively tight, wet, damaged, or foul-smelling
  • New drainage, spreading redness, fever, or wound concerns

See our full When to Call page for the difference between routine office contact and emergency evaluation.

Chest pain, shortness of breath, or symptoms of a possible blood clot, or any life-threatening emergency — call 911 or go to the nearest emergency department.

Frequently Asked Questions

How long will I be in a cast, splint, or brace for a ankle fracture?

A short-leg splint (SLS) for about 2 weeks, then transition to a CAM boot (controlled ankle motion boot).

When can I return to work, school, driving, or sports after a ankle fracture?

Your surgeon will guide when it's safe to return to these activities based on how your specific fracture is healing. Follow the instructions given specifically to you.

Still Have Questions?

Every fracture heals differently. If you have questions about your treatment plan, reach out to Dr. Kee's office.
