title: Outcomes of the mini-open Outerbridge-Kashiwagi procedure according to preoperative radiocapitellar joint status.
abstract: OBJECTIVE
  To compare the clinical and radiological outcomes in patients treated with the mini-open Outerbridge-Kashiwagi procedure according to radiological grading of the radiocapitellar joint.
  
  
  METHODS
  Sixty-three patients with primary elbow arthritis diagnosed between March 2004 and February 2010 were enrolled. Patients without and with radiocapitellar arthrosis were assigned to groups 1 (n = 34) and 2 (n = 29), respectively. The mean follow-up period was 51 months. Clinical outcomes were compared between groups using the presence of resting elbow pain; Morrey pain score; the Mayo Elbow Performance Score; the Disabilities of the Arm, Shoulder and Hand score; and active range of motion. Radiological outcomes, including the presence of loose bodies and re-ossification of fenestration, were evaluated.
  
  
  RESULTS
  No patient in group 1 and 4 patients in group 2 reported resting elbow pain at the final follow-up examination. All pain was on the radial side, and it was aggravated in 2 patients. The Mayo Elbow Performance Score and Disabilities of the Arm, Shoulder and Hand score and active motion improved in both groups. No significant difference in the Morrey pain score, Mayo Elbow Performance Score, Disabilities of the Arm, Shoulder and Hand score, or active range of motion was observed between groups. Postoperative deterioration of radiological joint status was similar in the ulnohumeral and radiocapitellar joints of both groups. Re-ossification of the fossa fenestration did not differ significantly between groups.
  
  
  CONCLUSIONS
  We compared the outcomes of the mini-open Outerbridge-Kashiwagi procedure according to radiocapitellar joint status. Short-term results were satisfactory in both groups, but resting pain associated with newly developed anterior loose bodies led to a poor outcome in group 2.
