Wrist and finger conditions encompass a range of disorders affecting the complex anatomy of the hand. The wrist contains eight small carpal bones, while each finger has three bones (phalanges), and the thumb has two. These structures work with an intricate network of tendons, ligaments, nerves, and blood vessels. Common conditions include inflammatory disorders like arthritis, nerve compression syndromes such as carpal tunnel syndrome, tendon problems, and traumatic injuries. In Singapore, these conditions affect approximately 15-20% of adults, with higher prevalence among office workers, manual labourers, and older adults. The interconnected nature of hand anatomy means problems in one area often affect overall hand function.
Carpal tunnel syndrome occurs when the median nerve becomes compressed as it passes through the wrist. Cubital tunnel syndrome affects the ulnar nerve at the elbow but causes symptoms in the ring and little fingers. These conditions typically develop gradually and worsen without treatment.
