Proximal phalanges (hand)
The proximal phalanges (hand) are the bones that are found at the bottom of the finger, also known as knuckles. They are named proximal phalanges due to being the closest bone to the hand. There are fourteen phalanges in each hand; three are located in the long fingers and two in each thumb. Injury to the phalanges includes: Closed bone fracture: broken bone that does not break through the skin Open bone fracture: broken bone that breaks through the skin, also known as a compound fracture Muscle strain: injury to the attached muscle that causes pain in the phalanges Luxation: a separation of the bone at the joint also known as dislocation The easiest way to treat an injury to the phalanges is to splint the finger for at least four weeks. Injuries to the proximal phalanges (hand) that are more serious will require surgery. It is imperative that individuals who have had proximal phalange (hand) surgery return to the surgeon for a follow-up visit at least two weeks after the surgery. The surgeon will take x-rays to observe the bone and ensure proper healing is taking place.
