Neuromas of the hand and upper extremity.
The painful neuroma is an often debilitating sequela of nerve injury about the hand. The exact pathophysiology of this condition is poorly understood. After sharp trauma to a peripheral nerve, as nerve ends try to connect with their end organs and "find" the distal nerve stump, fascicular escape and scarring can lead to the development of a painful neuroma. Painful neuromas can even be associated with blunt trauma or retraction of a nerve when the nerve is not actually divided. Green's definition of a neuroma is "the inevitable, unavoidable, and biologic response of the proximal stump after it has been divided in situations where regenerating axons are impeded from re-entering the distal stump."(1) A number of unknown factors make certain patients more susceptible to neuroma formation. In addition, certain nerves such as the superficial radial nerve are more prone to the development of a painful neuroma. Treatment of neuromas of the hand is important because they can be quite debilitating and painful, often preventing patients from continuing with their normal daily activities. There are a number of approaches to the painful neuroma, and the treatment plan must be tailored to the individual patient.
