Xray Foot Charting: sagittal plane views

Talocalcaneal angle Angle formed by collum tali axis and calcaneal inclination axis. Sinus tarsi is obliterated with pronation

Collum tali axis line joining bisection of distal regular neck and proximal regular neck of talus. Talar declination angle 21° Angle formed by collum tali axis and plane of support. Angle increase with pronation.

Calcaneal inclination angle (18-22 degrees) a) inferior limit, distal facet of the calcaneus b) distal inferior limit of the calcaneal tuberosity c) Calcaneal inclination axis d) Plane of support e) Calcaneal inclination angle f) Most distal inferior contact point -Angle decreases with pronation

Boehler's Angle - (28-40 degrees) (1) line joining anterior process and posterior calcaneal facets (2) line joining most posterior process and posterior facets - angle always taken with calcaneal fractures and indicates relative declination of the posterior facet.

1st Metatarsal declination angle (20-30 degrees) (1) line joining bisection of distal and proximal regular shaft of 1st metatarsal. (2) Plane of support.
