The next joint, moving closer to the hand, is the proximal interphalangeal (PIP) joint. The thumb differs by only having two bones and one interphalangeal joint. [10] The injured finger may be examined to determine where the pain is worst. [3] If the finger is sprained or dislocated, pain will be worse at the joint rather than the bone. [3]
Symptoms are pain and tenderness at the radial side of the wrist, fullness or thickening over the thumb side of the wrist, painful radial abduction of the thumb, and difficulty gripping with the affected side of the hand. [2] Pain is made worse by movement of the thumb and wrist, and may radiate to the thumb or the forearm. [2]
The TMC joint is a synovial joint between the trapezium bone of the wrist and the metacarpal bone at the base of the thumb. This joint is a so-called saddle joint (articulatio sellaris), unlike the CMC joints of the other four fingers which are ellipsoid joints. [17] This means that the surfaces of the TMC joint are both concave and convex.

Joint cracking is the manipulation of joints to produce a sound and related "popping" sensation. It is sometimes performed by physical therapists, chiropractors, and osteopaths [1] pursuing a variety of outcomes. The cracking of joints, especially knuckles, was long believed to lead to arthritis and other joint problems.
Infectious tenosynovitis in 2.5% to 9.4% of all hand infections. Kanavel's cardinal signs are used to diagnose infectious tenosynovitis. They are: tenderness to touch along the flexor aspect of the finger, fusiform enlargement of the affected finger, the finger being held in slight flexion at rest, and severe pain with passive extension.
Heberden's nodes typically develop in middle age, beginning either with a chronic swelling of the affected joints or the sudden painful onset of redness, numbness, and loss of manual dexterity. This initial inflammation and pain eventually subsides, and the patient is left with a permanent bony outgrowth that often skews the fingertip sideways.
