Charcot Joint Management When Total Contact Casting Has Not Achieved Resolution
When the initial immobilisation strategy for Charcot joint has not produced the required clinical and radiographic endpoints, a structured next-line approach becomes necessary. This protocol covers that subsequent step.
The preceding line of management — immobilisation with total contact casting (TCC) or an irremovable knee-high orthosis with strict non-weight-bearing — did not achieve the required endpoints: a sustained temperature differential of less than 2 °C between corresponding foot sites over 4–6 consecutive weeks, complete resolution of warmth, swelling, and erythema, and weight-bearing radiographic confirmation of the remodelling phase.
While conservative management with TCC remains the first-line treatment, surgical intervention becomes necessary in specific scenarios — the types of procedures, their selection criteria, and sequencing are set out in full within the complete protocol.
- Stable plantigrade foot
- Bony fusion evident on foot radiograph at 8–14 weeks
- Resolution of inflammatory changes on foot MRI

- More extensive reconstruction aims to create a stable, plantigrade foot through arthrodesis procedures.
- This approach is particularly valuable for severely unstable feet or those with recurrent ulceration after failed conservative or simpler surgical treatments.
- The transition to protected weight-bearing can be initiated when bony fusion is evident (8–14 weeks).
- Serial MRI monitoring every 3 months until resolution of inflammatory changes (average 8.3 months) helps determine appropriate immobilisation duration.
