Modified Percutaneous Hallux Abductovalgus Correction.

Percutaneous surgical techniques and minimally invasive procedures in foot and ankle surgery are gaining interest for both patients and surgeons. Percutaneous surgery is defined by a soft tissue or osseous procedure performed through the smallest possible incision without direct visualization of the underlying target structures. Percutaneous surgery has many potential advantages, including quicker operative times, multiplanar osteotomy correction, smaller incisions, decreased scarring, lower complication rates, and faster recovery times. The potential disadvantages include the need for specific equipment, that it cannot be used for large deformities, and that it requires an extensive learning curve. A commonly attempted percutaneous procedure is first metatarsal osteotomy for correction of hallux abductovalgus or bunion. We present our preoperative planning and intraoperative techniques for percutaneous hallux abductovalgus correction.
