Overview

To assess radiological and functional outcomes of modified extra-articular lateral column lengthening procedure for correction of adult acquired flexible flatfoot deformity

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(10), normal ranges of between 10-25° and 20-30 have Been proposed(11) 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) , typically', Meary's angle is 0°, with abnormal values considered angle \>4° convex upward: pes cavus , angle \<-4 convex downward: pes planus, It can be used to classify the severity of deformity 3. lateral talocalceneal angle : the angle between the calcaneal inclination axis and the mid-talar axis , The lateral talocalcaneal angle should normally measure between 25 and 40°, \>40° diagnoses flatfoot deformity(12) 4. Talonavicular coverage angle: it is the medial angle between ( talar head articular surface and Proximal navicular articular surface) ,Interpreting the talonavicular coverage angle (13)Normal: \<7,Adult Acquired flatfoot disease: \>7°

Interventions

Extra-articular Lateral Column Lengthening ProcedurePROCEDURE

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

Outcomes

Primary Outcomes

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

Time frame: 3 months after the surgery

Secondary Outcomes

clinical outcome by American orthopedic foot and ankle score (hindfoot

Time frame: 6 months after the surgery when the patient restore his life activities maximally
