From the Research

Diabetic hand clawing requires prompt medical attention, and treatment should focus on improving glycemic control, physical therapy, and pain management to slow progression and improve quality of life. The condition is a complication of diabetes, characterized by limited joint mobility, thickening of the skin, and contractures of the fingers. According to the most recent study 1, the diabetic hand is a neglected complication that requires increased awareness among healthcare professionals.

Pathophysiology and Clinical Presentation

The condition occurs due to prolonged hyperglycemia, leading to glycation of proteins in connective tissues, causing collagen cross-linking and thickening of the skin and joint capsules, which restricts hand mobility and creates the characteristic clawed appearance. Studies have shown that diabetic hand syndrome affects about 30% of patients with insulin-requiring juvenile diabetes 2.

Treatment and Management

Treatment should include:

  • Improving glycemic control through proper diabetes management, maintaining blood glucose levels within target ranges (typically fasting glucose 80-130 mg/dL and HbA1c below 7%) 3
  • Physical therapy with specific hand exercises, such as finger stretching, tendon gliding exercises, and wrist extension movements, each held for 20-30 seconds and repeated 5-10 times
  • Regular use of moisturizing creams containing urea or lactic acid to maintain skin elasticity
  • Pain management with acetaminophen (500-1000mg every 6 hours, not exceeding 4000mg daily) or NSAIDs like ibuprofen (400-600mg three times daily with food), though NSAIDs require caution in patients with kidney issues
  • In severe cases, corticosteroid injections might be considered

Importance of Early Intervention

Early intervention is crucial as advanced cases may become irreversible. The diabetic hand can reveal substantial pathology in diabetes, and clinical examination should not ignore it 4. By prioritizing glycemic control, physical therapy, and pain management, healthcare professionals can improve the quality of life for patients with diabetic hand clawing.
