This friction often causes bony growths called bone spurs to form around the joints. If you have these bone spurs in your fingers, they can lead to Heberden's nodes.

The bone under the nail that makes up the tip of the thumb is called the distal phalanx. The next bone is called the proximal phalanx. The distal phalanx and proximal phalanx connect via the interphalangeal (IP) joint, which allows you to bend the tip of your thumb. The thumb connects to the hand through the next joint, known as the ...

Plain radiographs form the mainstay of imaging distal phalanx fractures. The presence or absence of an intra-articular component, degree of comminution, and fracture displacement should be assessed when formulating a report.

This report presents two cases of thumb distal phalanx enchondromas successfully treated using a modified palmar approach with Bruner’s incision followed by splitting the insertion of the flexor pollicis longus tendon. Both patients achieved complete curettage, bone regeneration, and full preservation of thumb function at the 1-year follow-up.
