Charcot's joint of foot — Clinical Guidelines

Overview

Charcot's joint of the foot, also known as neuropathic arthropathy, is a progressive degenerative joint disease resulting from loss of sensation due to peripheral neuropathy, often seen in diabetic patients. It leads to bone destruction, joint dislocation, and severe deformities if not promptly managed. 1 6

Diagnosis

Clinical Presentation: Presence of neuropathy, unexplained joint pain, swelling, and deformity.

Imaging: Radiographs often initially normal; MRI, CT scans, or bone scintigraphy may reveal early changes.

Grading Systems: Eichenholtz classification for staging severity; Schon classification for midfoot involvement. 3 6

Management

Early Intervention: Off-loading with total contact casting to reduce pressure and prevent further bone damage. 6

Surgical Options: Multidisciplinary team (MDT) approach supports surgery even without optimal preoperative glycemic control (HbA1c <8.5%). 1

Reconstructive Techniques: Incorporation of bone grafts and internal fixation for severe deformities (Sanders and Mrdjenovich patterns 2 and 3). 8

External Fixation: Use of ring external fixators for complex deformities, particularly in trauma settings. 5

Glycemic Control: While optimal HbA1c targets are recommended, surgery can proceed safely in suboptimal glycemic states with MDT oversight. 1

Special Populations

Comorbidities: Management strategies should consider comorbidities like obesity, which may complicate surgical approaches and recovery. 5

Key Recommendations

Proceed with Surgery Despite Suboptimal Glycemic Control: Surgery for Charcot foot can be safely performed by a multidisciplinary team even when preoperative HbA1c targets are not met, acknowledging potential risks but emphasizing timely intervention. (Evidence: Moderate 1)

Utilize Advanced Imaging for Early Detection: Employ MRI, CT scans, or bone scintigraphy to detect early changes in Charcot foot when plain radiographs are inconclusive, facilitating early intervention. (Evidence: Moderate 6)

Implement Multidisciplinary Approaches: Engage a multidisciplinary team for comprehensive management, including surgical interventions and external fixation techniques, tailored to the severity and complexity of deformities. (Evidence: Expert opinion 5 8)
