The distal end of the barrel-shaped deformity fracture is displaced to the radial side along with the hand, and the axis of the middle finger is not in the same plane as the axis of the radius. It is a unique deformity of the Coles fracture and is one of the most frequent fractures in the human body, accounting for 10% of all fractures, with the elderly and adults accounting for the majority. The cause is mostly due to indirect violence. The following diseases are also the causes of carpal spur deformity: 1. Fracture A fracture is a complete or partial break in the continuity of a bone structure. It is mostly seen in children and elderly people, but it also occurs in young and middle-aged people. Patients often have a single fracture, but a few have multiple fractures. After timely and appropriate treatment, most patients can recover their original function, but a few patients may have different degrees of sequelae. The carpal tunnel syndrome is the most common type of peripheral nerve entrapment syndrome, which occurs in middle-aged people and is a series of symptoms and signs caused by the entrapment of the median nerve at the wrist. 3.Carpal ulnar tunnel syndrome The carpal ulnar tunnel syndrome refers to the symptoms and signs of sensory and motor dysfunction caused by any factors that cause compression of the ulnar nerve in the ulnar fibrous canal of the wrist. 4.Wrist navicular fracture Wrist navicular fracture is relatively common, mostly occurs in young adults, and is often caused by indirect violence. The palm of the hand touches the ground when falling, the wrist is dorsiflexed with strength, slightly radially deviated, and the dorsal edge of the radius cuts the navicular bone. After the injury, local swelling, pain, wrist joint movement is limited and pain is aggravated. There was pressure pain at the nasopharyngeal fossa and navicular tuberosity. Longitudinal percussion pain of the 2nd and 3rd metacarpal bones.
