[Modified distal osteotomy of shortening the first metatarsal for treatment of hallux valgus].
The results of distal osteotomy of shortening the first metatarsal with internal fixation of shape, memory metal compression staple for hallux valgus were evaluated in 26 feet of 17 women with a mean age of 41.0 years (30-65 yrs). The average time for return to light work was 18.2 days, and to full work and normal walk 40.3 days after the operation. 16 patients (25 feet) had complete relief from pain. Only in one foot the pain was transferred under the 2nd metatarsal head. The appearance of the feet was apparently improved and the width of the forefeet was decreased in a mean 0.92cm after the operation. All of the patients were satisfied with the appearance of their feet. Radiographic analysis of feet showed that all the osteotomies united, the average angle of hallux valgus was improved from 30.1 degrees to 16.0 degrees and the mean intermetatarsal angle from 11.2 degrees to 6.5 degrees. This new technique allows no external fixation of plaster splintage and the distal fragment during healing of the osteotomy was stable. The time of bone healing was shortened and patients were allowed to bear weight at early time.
