Interruption of left arm radius: the peripheral annular articular surface is related to ulna; The lower part of the head is slightly thinner, called radial tuberosity, and there are protrusions on the inner lower side of the radial neck. The radial body is bipyramidal, and its inner edge is a thin and sharp interosseous edge.

Distal fracture: about110 of normal fracture. It is more common in elderly women, and young adults are victims of traumatic violence. The fracture occurred within 2 ~ 3 cm of the distal radius. It is often accompanied by injuries of the radiocarpal joint and the lower radioulnar joint.

Extended data:

The treatment of distal radius fracture depends on whether the articular surface is involved or not: manual reduction, plaster, splint and external fixation can be used if the articular surface is not involved; Those who involve the articular surface should keep the articular surface flat or uneven.

Patients with epiphyseal cortical collapse were treated with prying reduction and bone grafting, postoperative plaster external fixation and early rehabilitation. AO classification system is recognized as a comprehensive and practical classification method, which plays a great guiding role in the selection of surgical approach, fixation method and prognosis evaluation.

Type C fracture should be anatomically reduced and firmly fixed as far as possible, and functional exercise should be carried out early to restore the labor force as soon as possible. Type B fracture can be reduced, and surgical treatment can be selected if the reduction is not satisfactory; The curative effect of type A fracture reduction and plaster fixation is reliable.
