Percutaneous techniques are currently more and more used in many surgical procedures on the soft tissues and bones of the foot. Practical advantages include lower complication rates and faster recovery times. Potential disadvantages are related to the need for specific equipment and extensive learning curve. One of the most frequent techniques involves a combination of chevron osteotomy of the first metatarsal with osteotomy of the first phalanx, both internally fixated. Lateral metatarsal misalignment and toe deformities can also be addressed by percutaneous treatment, with lower morbidity rates than open techniques. The most commonly performed percutaneous procedures are described, with their current indications, outcomes, and recent developments.
