Purpose
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.
Type of study/level of evidence
