Pdf Summary
This document provides information on carpometacarpal (CMC) arthritis and osteoarthritis of the hand/wrist. Here is a summary of the key points: 1. <strong>Carpometacarpal (CMC) Arthritis</strong>: - <strong>Prevalence</strong>: Older, menopausal women are more commonly affected by CMC arthritis of the thumb compared to younger, active men. The prevalence of this condition ranges from 11% to 33%. - <strong>Joint Characteristics</strong>: The first CMC joint is susceptible due to its range of motion in three planes: adduction-abduction, flexion-extension, and axial rotation. Laxity in this joint is a risk and early sign of arthritis. - <strong>Commonality</strong>: Although significant, the first CMC joint is not the most commonly affected joint in the hand or wrist with osteoarthritis. It ranks second, following the more commonly affected finger joints (proximal interphalangeal [PIP] and distal interphalangeal [DIP]). 2. <strong>Osteoarthritis of the Hand/Wrist</strong>: - <strong>Indicators</strong>: Heberden and Bouchard nodes are primary indicators of osteoarthritis in the hands. Heberden nodes appear at the dorsal DIP joints, while Bouchard nodes occur at the dorsal PIP joints. - <strong>Other Conditions</strong>: Differentiate osteoarthritis from conditions like Janeway lesions, which are related to endocarditis, Dupuytren’s contracture, ganglion cysts (commonly found on the wrist), and trigger finger (related to thickening of the flexor tendon sheath). This study guide provides foundational knowledge required to identify and distinguish between various arthritic conditions affecting the hands, particularly focusing on CMC arthritis and hand osteoarthritis. References from medical journals and online medical resources accompany the explanations, supporting further exploration and study.
