Lateral column lengthening (LCL), originally described by Evans, is an established procedure to correct stage II adult acquired flatfoot deformity (AAFD). However, the relative position between the facets is violated, and other problems may include nonunion, malunion, and calcaneocuboid (CC) joint subluxation. Herein, we report a modified extra-articular technique of LCL with hockey-stick osteotomy, which preserves the subtalar joint as a whole, increases bony apposition to enhance healing ability, and preserves the insertion of the calcaneofibular ligament to stabilize the posterior fragment to promote adduction of the forefoot
Radiological outcome & by standard erect plain x ray after 3 months
Measurement of 1. Calcencal pitch : this angle is formed on a weight-bearing lateral foot radiograph between the calcaneal Inclination axis and the supporting horizontal surface , correction angle needed ≈ 15-25°. 2. Meary's angle: It is the angle between a line drawn along the longitudinal axis of the talus (mid-talar axis) and the first metatarsal (first metatarsal axis) , correction angle needed ≈ 0-1°. 3. lateral talocalceneal angle : the angle between the calcaneal inclination axis and the mid-talar axis correction angle ≈ 25 and 40° . 4. Talonavicular coverage angle: it is the medial angle between ( talar head articular surface and Proximal navicular articular surface
