Long-term results of the minimal resection Darrach procedure.
Eighteen patients had a minimal resection Darrach procedure at the distal radial-ulnar joint for treatment of posttraumatic arthritis. The follow-up averaged 8 years (range, 2 to 18 years). Fourteen patients were completely satisfied with the result achieved with the procedure and four were mostly satisfied. No patient had either subjective or objective evidence of distal ulnar instability. Grip strength for patients without radiocarpal arthritis was 84% of the uninvolved side. Preoperative ulnar variance was plus 4 mm and at follow-up minus 4 mm. At follow-up examination, four patients had ulnar carpal translocation. The average radial inclination angle of the patients with ulnar carpal translocation was 24 degrees, compared with 18 degrees for patients without ulnar carpal translocation. The minimal resection Darrach procedure gives excellent relief of pain without the instability attributed to the Darrach procedure. It must be used judiciously in patients who have a radial inclination angle above 23 degrees.
