Results of compression-plating of closed Galeazzi fractures.

Diaphyseal fractures of the distal third of the radius that are associated with disruption of the distal radio-ulnar joint accounted for eighty-four (6.8 per cent) of 1236 fractures in the forearm that were treated during a five-year period at the Los Angeles County-University of Southern California Medical Center. Thirty-six closed Galeazzi fractures, twenty-eight in male and eight in female patients, were followed for 1.5 to seven years after treatment using standard AO-compression plates with four to seven holes. Complications included seven injuries to the sensory or dorsal interosseous branch of the radial nerve, two infections, two non-unions, two re-fractures after plate removal, and shortening of the radius of five millimeters in one patient. The complication rate was 39 per cent. The average grip strength at follow-up was 71 per cent of the calculated normal value. The loss of strength was not related to use of a volar or dorsal surgical approach, the patient's age, or a delay of surgery for more than ten days after injury. The average loss of grip strength in the seven upper extremities with restricted motion of the wrist and forearm was 48 per cent, compared with an average loss of 29 per cent in the whole group. Of the twelve patients who were operated on more than ten days after injury, six had loss of motion at follow-up, compared with three who had such a loss among the twenty-four patients who were operated on within ten days after injury.(ABSTRACT TRUNCATED AT 250 WORDS)
