title: Deformity correction using supramalleolar gigli saw osteotomy and Taylor spatial frame: how to perform this osteotomy safely?
abstract: Supramalleolar osteotomy (SMO) is useful for the correction of various deformities around the ankle joint,especially deformities of the distal tibia secondary to partial growth arrest, foot equinus, and hind foot deformities. By definition, this osteotomy cuts through the tibia and fibula approximately 2–3 cm above the ankle joint.It can be performed by various techniques, each of them have advantages and disadvantages. Gigli saw SMO can be performed percutaneously with minimal soft tissue dissection, leaving a very smooth bone surface, which is especially useful for the correction of rotational deformities. Over a period of 6 years we performed eight gigli saw SMO in seven male patients and one female patient with a mean age of 13.6 years. All patients had multiplanar deformities with some shortening (range 15–40 mm) and underwent correction and lengthening by Taylor spatial frame. Treatment goal was achieved in all patients with minimal complications. On the basis of our experience, we believe that gigli saw SMO can be performed safely. This osteotomy, in conjunction with the Taylor spatial frame, became our treatment of choice for the correction of ankle and hindfoot deformities.The evidence is level 4, case series.
