| Abstrakt: | Introduction: Metatarsal pronation is present in 87% of patients with hallux valgus (HV) deformity. The chevron osteotomy is commonly used worldwide to correct mild to moderate HV deformities. Many modifications have been described, but few address the rotational deformity of the first metatarsal. The rotational biplanar chevron osteotomy (RBCO), described by M. Prado et al, presents a variation of a biplanar chevron osteotomy that can be used to address first metatarsal rotation. The objective of this study is to investigate and verify the technique of the RBCO. Methods: We conducted our study performing an RBCO on 9 cadaveric limbs. The technique uses a medial-based wedge parallel to the plantar limb of the osteotomy to make the distal fragment free to correct rotation. A goniometer was used by 2 individual surgeons to control the rotational correction achieved. Results: The osteotomy was considered simple to perform and we experienced no complications, such as fractures or instability. The result was satisfactory alignment and adequate stability. On average, a 2 mm wedge resulted in 11° of rotational correction. Conclusion: We predict that RBCO can safely be used for correcting the metatarsal rotation when necessary in mild to moderate HV deformity foot. Levels of Evidence: Level IV.
