Carpal bossing is defined as the presence of a bony lump on the rear part of the hand. This bump is produced by a small region of osteoarthritis forming at the connection point of the elongated hand bones and miniature wrist bones.
It is characterized as a lump on the rear part of the hand at the center or index carpometacarpal joint.
The condition is brought about by the bony growth at the base of the metacarpal bones of the hand.
What are the indications?
Generally, an individual might complain of carpal bossing after hitting or bumping the back of the wrist. Remember that this form of damage is considered as a form of irritant to the carpal boss.
The tendons above the rear of the hand are also irritated due to carpal bossing. Oftentimes, there is snapping of the tendon as it glides over the bump. In addition, some find the presence of the bump undesirable.
Management of carpal bossing
Most often, carpal bossing is an issue that is simply monitored and does not require specific treatment. Anti-inflammatory analgesics might be suggested if it is inflamed or painful. In case there is pain or discomfort, the doctor might recommend a wrist splint to limit movement or a steroid shot if the splint could not provide relief.
In case the condition results to serious symptoms, a surgical procedure might be required to remove the excess bone. This procedure might require a local or regional anesthetic. During the procedure, an incision is created on the back part of the hand and the bump or any inflamed tissue surrounding it are eliminated. The individual can utilize the affected hand for normal activity after a few days.
