Apleys 8e, p 750-75; Ebnezar Ohopedics 3e, p 263-264; Maheshwari 3e, p 1401 Bohlers angle also ka Tuber joint angle measures the angular relationship between talus and calcanecum. Flattening of this angle is a classic x-ray sign of depressed fracture of calcaneum. Other angle which is of impoance in calcaneal fracture is Crucial angle of Gissane More about calcaneal Calcaneum is the most commonly fractured tarsal bone In 5-10 of cases is bilateral Most common mechanism of injury is fall front height, often from a ladder, onto one or both heels. The calcaneum is driven up against the talus and is split or crushed. About one fifth of these patients suffer associated injuries of the spine, pelvis or hip. Also ka loveri fracture Plain x-rays done for calcaneal fracture include lateral, oblique and axial views, Axial view of calcaneum is also ka Hans view. CT is the inv. of choice With severe injuries and especially with bilateral fractures - it is essential to x-ray the knees, the spine and the pelvis as well Other angles of impoance Cobbs angle - Scoliosis Apleys 8e, p 377; Maheshwari 3e, p 235 Kites angle - CTEV Apleys 8e, p 489; Maheshwari 3e, p 196 Mearys angle _ Pes cavus plantaris Apleys 8e, p 497 deformity Hilgenreiners epiphyseal angle Congenital coxa vera Apleys 8e, p 420 Baurnanns angle Supra condylar Apleys 8e, p 597 C alcaneum 1Ref.
