    Abstract:
    UNLABELLED: Brachymetatarsia is an abnormal shortening of a metatarsal. It causes disruption of the normal metatarsal parabola, resulting in metatarsalgia, calluses and dislocation of the digits. Patients often express discontent with the appearance of their feet. Lengthening by distraction osteogenesis and 1-stage intercalary bone grafting procedures are the mainstays of operative treatment. We present a modified 1-stage technique, combining the use of a Chevron osteotomy of the fourth metatarsal with shortening osteotomies of the second and third metatarsals. Bone removed from the third metatarsal was used to lengthen the fourth. The Chevron segments provided mediolateral, dorsoplantar, and rotational stability. The technique was used on both feet of 1 patient. The mean increase in AOFAS score was 34.5 (right foot, 46; left foot, 23.) There were no complications. A 1-stage technique does not require an external fixator or postoperative manipulation and has a quicker healing time. Taking the bone graft from neighboring metatarsals decreases the discrepancy between metatarsal lengths. A smaller increase in the length of the fourth ray is then required, and the chance of neurovascular injury as a result of soft-tissue stretching is minimized. This technique allows restoration of the metatarsal parabola and provides good correction, immediate stability, and good integration. LEVELS OF EVIDENCE: Therapeutic Level IV, Case Study.
