Abstract
The current study aimed to assess the outcomes of sliding oblique metatarsal osteotomy
fixated with a K-wire without cheilectomy for hallux rigidus. Pre- and postoperative
variables, including dorsiflexion angle, visual analog scale score, and Japanese Society
for Surgery of the Foot scale score, were assessed using the Wilcoxon signed-rank
test. In addition, the surgical effects among the four grades were compared using
the Kruskal-Wallis test. In total, 43 patients, including 11, 11, 15, and 6 with grade
1, 2, 3, and 4 hallux rigidus, respectively, were enrolled in this analysis. The mean
age of the participants was 56.2 years, and the mean follow-up period was 3.0 years.
Mean pre- and postoperative dorsiflexion angles were as follows: overall, 53.0° to
66.5° (p < .001); grade 1, 66.8° to 79.1°; grade 2, 59.1° to 68.6°; grade 3, 43.3° to 61.0°;
and grade 4, 40.8° to 53.3°. Mean pre- and postoperative visual analog scale scores
were as follows: overall, 70.1 to 6.5 (p < .001); grade 1, 74.2 to 3.0; grade 2, 66.4 to 7.6; grade 3, 69.5 to 8.4; and grade
4, 71.2 to 6.0. Finally, mean pre- and postoperative Japanese Society for Surgery
of the Foot scale scores were as follows: overall, 61.2 to 86.6 (p < .001); grade 1, 63.8 to 93.6; grade 2, 68.3 to 85.9; grade 3, 54.4 to 83.1; and
grade 4, 60.5 to 83.5. There was no statistically significant difference in the surgical
effects among the four grades. Decompressive metatarsal osteotomy without cheilectomy
was found to be effective. Moreover, the procedure could be performed for all grades
of hallux rigidus.
