During osteotomy, the metacarpal is cut and a wedge shape bone fragment is removed to move the bone away from the hand. [35] Postoperative, the thumb of the patient is immobilized using a thumb-cast. Possible complications are non-union of the bone, persistent pain related to unrecognized CMC or pantrapezial disease and radial sensory nerve injury.
Exostoses are sometimes shaped like spurs, such as calcaneal spurs. Osteomyelitis , a bone infection, may leave the adjacent bone with exostosis formation. Charcot foot , the neuropathic breakdown of the feet seen primarily in diabetics , can also leave bone spurs that may then become symptomatic.
Ganglion cysts have been found to recur following surgery in 12% [29] to 41% [30] of patients. A six-year outcome study of the treatment of ganglion cysts on the dorsal wrist compared excision, aspiration, and no treatment. Neither excision nor aspiration provided long-term benefit better than no treatment.
De Quervain syndrome is diagnosed clinically based on patient history and physical examination, though diagnostic imaging may be used to rule out fracture, arthritis, or other causes. The modified Eichoff maneuver , commonly referred to as the Finkelstein test , is a physical exam maneuver used to diagnose de Quervain syndrome. [ 2 ]
Hereditary multiple osteochondromas (HMO), also known as hereditary multiple exostoses, is a disorder characterized by the development of multiple benign osteocartilaginous masses in relation to the ends of long bones of the lower limbs such as the femurs and tibias and of the upper limbs such as the humeri and forearm bones.
Carpometacarpal bossing (or metacarpal/carpal bossing) is a small, immovable mass of bone on the back of the wrist. The mass occurs in one of the joints between the carpus and metacarpus of the hand , called the carpometacarpal joints , where a small immovable protuberance [ 1 ] occurs when this joint becomes swollen or bossed.
The symptoms are pain and tenderness in the specific location of the hand, which corresponds to the metacarpal bone around the knuckle. When a fracture occurs, there may be a snapping or popping sensation. There will be swelling of the hand along with discoloration or bruising in the affected area.
Anterior interosseous syndrome is a medical condition in which damage to the anterior interosseous nerve (AIN), a distal motor and sensory branch of the median nerve, classically with severe weakness of the pincer movement of the thumb and index finger, and can cause transient pain in the wrist (the terminal, sensory branch of the AIN innervates the bones of the carpal tunnel).
