Abstract

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.

一项尸体解剖研究,验证旋转式双平面Chevron截骨术矫正三维Hallux Valgus畸形的潜力。
引言87%的拇外翻(HV)畸形患者存在跖骨内旋。人字形截骨在世界范围内普遍用于矫正轻度至中度HV畸形。已经描述了许多修改,但很少涉及第一跖骨的旋转畸形。M.Prado等人描述的旋转式双平面人字形截骨(RBCO)是可用于解决第一跖骨旋转的双平面人字型截骨的变体。本研究的目的是研究和验证RBCO技术。方法:我们对9具尸体肢体进行了RBCO研究。该技术使用平行于截骨足底的内侧楔形物,使远端碎片自由旋转。两名外科医生使用角度计来控制所实现的旋转矫正。结果截骨术被认为是简单的,我们没有经历并发症,如骨折或不稳定。结果是令人满意的对准和足够的稳定性。平均而言,一个2毫米的楔块导致11°的旋转校正。结论我们预测RBCO可以在必要时安全地用于矫正轻度至中度HV畸形足的跖骨旋转。证据水平IV级。
