Leclercq syndrome, commonly known as Mannerfelt syndrome, refers to the isolated rupture of the flexor pollicis longus (FPL) tendon in patients with rheumatoid arthritis (RA). Chronic inflammation within the carpal tunnel leads to tendon degeneration and eventual rupture. Timely identification and intervention are crucial for restoring thumb function and preventing further disability.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    Conditions to differentiate from isolated FPL rupture include:<\/p>

    • Anterior Interosseous Nerve (AIN) Palsy:<\/strong> Weakness of FPL and flexor digitorum profundus to index finger without sensory deficits.<\/p><\/li>

    • Trigger Thumb:<\/strong> Thumb locking or catching from stenosing tenosynovitis; thumb flexion generally preserved.<\/p><\/li>

    • Carpal Tunnel Syndrome:<\/strong> Median nerve compression causing sensory symptoms and weakness without isolated FPL rupture.<\/p><\/li>

    • Flexor Tendon Laceration:<\/strong> Associated with trauma and visible skin injury.<\/p><\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

        2. Tendon Grafting:<\/strong> Palmaris longus tendon graft bridging in cases unsuitable for direct tendon transfer.<\/p><\/li>

        3. Tenosynovectomy:<\/strong> Removal of inflamed synovium within the carpal tunnel to prevent further damage.<\/p><\/li>

        4. Carpal Tunnel Release:<\/strong> Simultaneous decompression to reduce pressure on median nerve and tendons.<\/p><\/li>
