Dorsiflexory Wedge First Metatarsal Osteotomy.

Area of Science:

• Orthopedic surgery
• Podiatric surgery
• Foot and ankle reconstruction

Background:

• Symptomatic plantarflexed first ray often presents with forefoot-driven hindfoot varus deformity.
• Correction of this deformity is crucial for restoring normal foot biomechanics.

Purpose of the Study:

• To describe the technique and utility of dorsiflexory wedge first metatarsal osteotomies.
• To highlight the role of Meary's angle in assessing surgical correction.

Main Methods:

• The procedure involves a dorsiflexory wedge osteotomy at the proximal metaphysis of the first metatarsal.
• It is performed distal to the first tarsometatarsal joint.
• Often combined with hindfoot osseous and soft tissue procedures.

Main Results:

• Restoration of Meary's angle provides intraoperative radiographic and clinical assessment of correction.
• The osteotomy addresses forefoot valgus deformity.
• High union rates are reported with various fixation options.

Conclusions:

• Dorsiflexory wedge first metatarsal osteotomies are pivotal for structural correction of the plantarflexed first ray.
• This technique aids in correcting forefoot valgus and restoring Meary's angle.
• The procedure is versatile and achieves high union rates.
