Osteoarthritis (OA) is the most common degenerative joint disease affecting the hand. It is characterized by progressive loss of articular cartilage, subchondral bone remodeling, and osteophyte formation, leading to pain, stiffness, and functional limitations. OA typically affects the base of the thumb (CMC joint), distal interphalangeal (DIP) joints, and proximal interphalangeal (PIP) joints<\/strong>. Understanding its pathophysiology and clinical manifestations is essential for optimizing treatment strategies, both conservative and surgical.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The pathophysiology of hand OA is multifactorial and begins with mechanical wear and tear on articular cartilage. Key mechanisms include:<\/p>

  • Chondrocyte injury<\/strong> due to repetitive stress.<\/p><\/li>

  • Inflammatory mediators<\/strong> (IL-1\u03b2, TNF-\u03b1) accelerating cartilage degradation.<\/p><\/li>

  • Subchondral bone sclerosis<\/strong> and osteophyte formation.<\/p><\/li>

  • Joint space narrowing and misalignment<\/strong>, leading to instability and deformity.<\/p><\/li><\/ul>

    These changes result in pain, limited range of motion, and impaired grip strength<\/strong>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

                Hand OA is a progressive disorder with significant implications for daily function. Its pathophysiology involves cartilage loss, subchondral bone changes, and osteophyte formation driven by mechanical stress and biochemical mediators. Clinically, it presents with hallmark signs like joint crepitus, nodularity, and reduced grip strength. Current management strategies emphasize conservative treatment, with surgery reserved for severe cases<\/strong>. A multidisciplinary approach<\/strong> is key to optimizing long-term outcomes.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
