To determine the influence of osteoporosis on the results of percutaneous K-wire fixation for distal radius fractures.

Between March 2007 and February 2011, Fifty seven patients who underwent fixative surgery with K-wires after closed reduction and those available for follow-up for at least 6 months were reviewed. They were divided into the two groups of T score -3 or more (group 1) and T score less than -3 (group 2). These groups were compared by the range of motion of the wrist and Disabilities of the Arm, Shoulder and Hand (DASH) score. Radiologic evaluations consisting of radial length, radial inclination and volar tilt were compared. In group 1 with 34 cases, the average age was 65.4 years (50 to 78 years) and T score was -1.97 (-0.1 to -2.93). In group 2 with 23 cases, the average age was 74 years (54 to 89 years) and T score was -4.11 (-3.1 to -6.97).

There was no statistical difference between group 1 and group 2 in terms of range of motion, DASH score and radiologic evaluations.

In the case of no volar side cortical comminution, percutaneous K-wire fixation can be applied for the treatment of distal radius fracture with osteoporosis.
