  • Title: Compression screw fixation in proximal first metatarsal osteotomies for metatarsus primus varus: initial observations.
    Author: Gudas CJ.
    Journal: J Foot Surg; 1979; 18(1):10-5. PubMed ID: 263012.
    Abstract:
    Many methods of fixation have been used after proximal abductory metatarsal osteotomies for the correction of metatarsus primus varus. The methods include external immobilization and the application of devices such as stainless steel wire, Kirschner wires, staples, and compression plates. We have combined external immobilization with compression screw fixation across the osteotomy site. Two different types of screws were used: 1) an AO screw 3.6 mm. wide and 26 to 28 mm. long and 2) a standard Woodruff screw 3.5 mm. wide and 31.8 to 44.4 mm long. Twenty-two procedures were reviewed. When we compared the results, we found the AO screw to be superior in the degree of rigid fixation which it provides, as judged by the extent of postoperative callus formation.
