A bimalleolar fracture involves two of the bony prominences around the ankle joint; a trimalleolar fracture involves three. These are more complex ankle fracture patterns that often benefit from surgical stabilization.
This page explains how a bimalleolar or trimalleolar ankle fracture is commonly managed, in plain language, based on Dr. Kee's typical approach to this injury.
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.
A bimalleolar fracture involves two of the bony prominences around the ankle joint; a trimalleolar fracture involves three. These are more complex ankle fracture patterns that often benefit from surgical stabilization.
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.
A short-leg splint (SLS) for about 2 weeks, then transition to a CAM boot (controlled ankle motion boot).
No weight bearing (NWB) for about 2 weeks; patients with diabetes are typically kept non-weight-bearing for about 6–12 weeks.
For a full explanation of what these weight-bearing terms mean, see our Weight-Bearing Guide.
No resistance or strengthening (NRM) for about 6 weeks (12 weeks for patients with diabetes). If treated with surgery, motion (ROM) may begin around 2 weeks once the skin has healed, as you transition to a CAM boot.
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.
Every fracture moves through the same general phases, though the exact timing is different for every patient:
Your surgeon will guide when it's safe to return to work, school, driving, sports, or other activities based on your healing and this specific fracture. Follow the instructions given specifically to you.
See our full When to Call page for the difference between routine office contact and emergency evaluation.

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