Twenty three cases of intraaticular comminuted fracture of the distal radius were treated with closed reduction and percutaneous K-wire fixation under C-arm field and then immobilized by sugar tong spling and short arm cast from March 1987 to May 1991 at the department of orthopaedic surgery of Korea University Hospital. The mean follow up period of this patients was 14.4 months. A prospective study was and evaluated by the subjective criteria of Cole and Obletz, and the objective criteria of Scheck. The results of this study were as follow: l. Among 105 patients with distal radius fruvture, 23 patients (21,9%) had intraarticular comminuted fractures. 2. Generally Colles fracture occured more fraquently in women and in 6th and 7th decades, but comminuted intraarticular fracture of the distal radius was occurred in third and 4th decades and showed no sex related propencity. 3. The main mechanism of ingury caused intraarticular comminuted fracture was fall on the out stretched hand (19 patients) and there were no open fracture. 4. Overall assessments showed excellent in 6 patients (26%), good in 12 patients (52%), fair in 4 patients (17%), and poor in lpatient. Percutaneous pinning is considered to be ideal for simple intraarticdar fracture with fairly large and gard fragments. 5. Overall results were mainly correlated with initial severity of injury and resideal shortening of radius was associated with decreased forearm rotation.
