Medical Analysis Report

I. Radiological Findings

Based on the patient's bilateral hand anteroposterior X-ray images, the following findings are observed:

• The 2nd and 3rd metacarpophalangeal (MCP) joints in both hands show varying degrees of joint space narrowing.
• Subchondral sclerosis (sclerotic lines) and pronounced osteophyte formation can be noted, with the osteophytes appearing drooping in shape.
• Some joint surfaces appear “square-shaped,” suggesting abnormal joint surface contour.
• Possible localized cartilage calcification (which may indicate calcification in cartilage or fibrous tissue, and requires clinical correlation).

Overall, the findings are consistent with degenerative and metabolic disease-related joint changes.

II. Potential Diagnoses

1. Hemochromatosis Arthropathy
   Excessive iron deposition can lead to characteristic joint lesions, especially involving the 2nd and 3rd MCP joints. On X-ray, joint space narrowing, osteophytes, and subchondral sclerosis are commonly seen, possibly accompanied by chondrocalcinosis.
2. Osteoarthritis (OA)
   A degenerative joint disease that can present with joint space narrowing, osteophyte formation, and subchondral sclerosis. However, it most commonly affects the proximal interphalangeal (PIP), distal interphalangeal (DIP) joints, and the first carpometacarpal (CMC) joint, and is more frequently seen in middle-aged to older females.
3. Calcium Pyrophosphate Deposition Disease (CPPD)
   Also shows chondrocalcinosis, potentially involving the wrist and other large joints. Radiographically, calcification of cartilage or fibrocartilage may be present. However, when associated with hemochromatosis, chondrocalcinosis may occur alongside iron deposition, thus clinical and laboratory data are required for a definitive differential diagnosis.

III. Final Diagnosis

Taking into account the patient’s known history of hemochromatosis, multiple hand joint pain, and the characteristic X-ray changes (involvement of the 2nd and 3rd MCP joints, prominent osteophytes, joint surface sclerosis, and a “square-shaped” appearance), the most likely diagnosis is:

Hemochromatosis Arthropathy

IV. Treatment Plan and Rehabilitation Program

1. Treatment Strategies

• Etiological Treatment: The primary treatment for hemochromatosis is phlebotomy (repeated venesection) or iron chelators to reduce iron overload in the body and limit further damage to organs and joints.
• Symptomatic Management of Joints:
  • For patients with significant joint pain, non-steroidal anti-inflammatory drugs (NSAIDs) or short-term pain-relief medications may be considered.
  • If joint deformities or severe functional limitations are present, surgical treatment (e.g., joint arthroplasty) may be considered, with comprehensive evaluation of cardiac, pulmonary, and overall health status.
• Additional Supportive Therapies: Dietary adjustments, controlling iron intake, and regular monitoring of liver function and cardiac status.

2. Rehabilitation and Exercise Prescription

Rehabilitation exercises should be introduced gradually under pain control and joint protection, taking into account the patient’s overall condition and joint functionality.

• Phase-based Goals:
  • Early Phase: Alleviate joint pain and inflammation, maintain range of motion.
  • Intermediate Phase: Strengthen muscles, improve joint stability and function.
  • Late Phase: Restore or achieve basic daily activity capabilities.
• FITT-VP Principle Example:
  • Frequency: 3–5 times per week, with possible gradual increase depending on joint tolerance.
  • Intensity: Low to moderate, avoiding excessive joint loading; reduce workout volume in case of marked pain or swelling.
  • Time: Initially 20–30 minutes each session, gradually extending as tolerated by the joints.
  • Type: Low-impact aerobic exercises (e.g., walking, swimming, water aerobics), range-of-motion activities, and light resistance training.
  • Progression: Increase intensity and duration step by step, based on pain and recovery.
  • Volume and Personalization: Adjust the total exercise volume to the patient’s specific condition and modify accordingly based on daily joint symptoms.
• Specific Training Examples:
  • Range-of-motion exercises: Such as fist clenching, finger extension, and wrist rotations, 8–10 repetitions per set, 2–3 sets daily.
  • Water-based exercises: Gentle walking or stretching in a swimming pool, utilizing buoyancy to support the joints.
  • Light resistance training: Using resistance bands or light dumbbells for finger and wrist strengthening, 8–10 repetitions per set, with adequate rest and protection.
• Precautions:
  • If significant joint swelling or severe pain occurs, reduce the workout volume or pause exercise and seek medical evaluation.
  • In patients with hemochromatosis, be cautious about potential cardiac or liver involvement; monitor heart rate, blood pressure, and rest periods during exercise.
