In the treatment of Unstable fractures of the Distal Radius, selecting a right method of treatment that can give the best result is very difficult. Many complications can be developed if improper mothods are chosen o treat these fractures.

We analyzed 25 patients with unstable fractures of the distal raduis, being treated with open reduction and internal fixation with T-plate from May 1986 to December in 1994 and, being followed for more than 12 months.

The results were as follows;

1. In twenty-five patients, 17 cases were Cellosfractures, 2 cases Smith fractures and 6 cases Bartons fractures.

2. In follow-up roentgenogram, the mean values of the radial length, radial deviation, volar tilt and step-off are 18.8 mm,20.3 ,8 ,0.2mm respectively.

3. Recovery of wrist function was correlated with the degree of correction of volar tilt angle in the postoperative roentgenogram .

4. In 25 patients treated with open reduction and internal fixation using the T-plate, satisfactory result was obtained in 88% (22 cases) of patients, We concluded that this is the effective method for treating unstable fractures of the distal radius because this method permits early motion of the wrist by firm and stable fixation.
