ABSTRACT

PURPOSE:

To compare the clinical outcomes of the ulnar shortening osteotomy alone and the ulnar shortening osteotomy with arthroscopic debridement in the idiopathic ulnar impaction syndrome with positive ulnar variance. MATERIALS AND

METHODS:

Twenty seven cases, who underwent the ulnar shortening osteotomy with or without arthroscopic debridement for treatment of the idiopathic ulnar impaction syndrome with positive ulnar variance, were included. The mean age was 40.3 years (range, 21 to 63 years) and the mean follow-up period was 20.6 months (range, 12 to 60 months). The ulnar shortening osteotomy alone and the ulnar shortening osteotomy with arthroscopic debridement were performed in 14 and 13 cases respectively. Pre- and postoperative functional results of the wrist were evaluated by the modified Mayo wrist score.

RESULTS:

The ulnar variance was corrected from 4.61 mm (range, 1.8~10 mm) to -0.06 mm (range, -3.3~3.1 mm) in the ulnar shortening osteotomy alone group and from 3.01 mm (range, 1.2~7.6 mm) to -0.74 mm (range, -1.8~0 mm) in the ulnar shortening osteotomy with arthroscopic debridement group. The final results of the ulnar shortening osteotomy alone were excellent in 4 cases, good in 5 cases, and fair in 5 cases. Those of the ulnar shortening osteotomy with arthroscopic debridement group were excellent in 6 cases, good in 2 cases, fair in 1 case, and poor in 2 cases. The modified Mayo wrist score at the last follow-up were 83.57(range, 75~100) in the ulnar shortening osteotomy alone group and 83.35(range, 40~100) in the ulnar shortening osteotomy with arthroscopic debirdement group. No statistically significant difference was demonstrated between two groups (p=0.43).

CONCLUSION:

The ulnar shortening osteotomy is valuable treatment for the idiopathic ulnar impaction syndrome with positive ulnar variance. The combined arthroscopic debridment does not appear to have positive influence to the final results.
