First metatarsal fixed displaced distal percutaneous osteotomy in the metatarsus primus varus surgical correction

Abstract

The purpose of the study was to expand the possibilities of metatarsus primus varus percutaneous correction through the development of surgical technique, taking into account the advantages and disadvantages of known techniques. Materials and method: by the example of 67 surgeries the results of the first metatarsal displaced distal percutaneous osteotomy fixed by the screw were reviewed. Surgical technique was described. Proposed intervention was applicable over a wide range of the first intermetatarsal angle (from 12 to 29° in this series). Immediate fool weight-bearing was authorized. An average hospital stay was 1.02 due to the painless early postoperative period. Results: desired correction of the first metatarsal has been achieved in the course of all surgical interventions. Partial or complete loss of correction in the postoperative period, that did not affect final results, was registered in three patients after interventions on four feet. The average first intermetatarsal angle after surgery was 10.6 ° (4-16). No transfer metatarsalgia, infectious or other complications were noted, as well as unsatisfactory results. Conclusions: first metatarsal fixed displaced distal percutaneous osteotomy together with previously proposed percutaneous first metatarsocuneiform joint arthrodesis technique allows percutaneous correction of any degrees of metatarsus primus varus.
