Every finger has three joints. The thumb has two joints. These joints allow our fingers to bend and straighten.
A year-old man presented to the emergency department with the after being struck in the hand with a basketball. Clinical findings are seen in the image above. What are the common causes of failed reduction attempts in thumb interphalangeal IP joint dislocations?
PIP joint dislocation occurs when trauma causes the bones in the middle joint of a finger to dislodge. This usually results in a very painful, swollen and bruised joint that does not move properly, if at all. A sprain occurs when ligaments in a joint are torn or pulled and may occur without joint dislocation.

Dislocation of the interphalangeal IP joints is one of the most common orthopedic injuries seen in the Emergency Department ED. The proximal interphalangeal PIP joint is especially susceptible to injury during ball-handling sports.
Dislocation of the thumb interphalangeal IP joint is uncommon because of the inherent stability of the joint. Cases in which reduction was blocked by the volar plate, the flexor pollicis longus FPL tendon, the sesamoid bone, and an osteochondral fragment have been described in the literature. This article reports a case of closed thumb IP joint dislocation caused by the displacement of the FPL tendon.

Interphalangeal joint dislocations are common upper extremity dislocations. Although considered minor injuries by many, they can result in significant disability. The typical mechanism is a hyperextension injury.
Finger fractures and dislocations are common injuries that are often managed by family physicians. A systematic physical examination is imperative to avoid complications and poor outcomes following these injuries. Radiography commonly anteroposterior, true lateral, and oblique views is required in the evaluation of finger fractures and dislocations.
