Radiological Outcomes of Modified Extra-articular LCL
- Conditions
- Adult Acquired Flexible Flatfoot Deformity After Failure of Conservative Treatment
- Registration Number
- NCT06562062
- Lead Sponsor
- Assiut University
- Brief Summary
To assess radiological and functional outcomes of modified extra-articular lateral column lengthening procedure for correction of adult acquired flexible flatfoot deformity
- Detailed Description
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°

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
