The normal range is 20 to 40 degrees. Angles < 20 degrees is suggestive of a calcaneus fracture and/or disruption of the posterior facet. The critical angle of Gissane (G) and the Boehler angle (B) have also been drawn in. The Boehler angle is normally 20°–40°. Historically, physicians would measure Bohler’s angle and the critical angle of Gissane in cases where a calcaneal fracture was not clearly evident on a plain X-ray. Outlined in Figure 3, a calcaneal fracture would be suspected if Bohler’s angle was below 20 degrees or the critical angle of Gissane was noted to be more than 140 degrees. 2020-01-01 · Gissane‘s angle was hardly affected by deviation in the caudal direction (toward –30°); all 95% CIs spanned 0°.

In long-term follow-up, Böhler and Gissane angles were better in the bone graft group than in the non-bone graft group. However, Calcaneal height was not significantly different between the 2 groups. Bohler and Gissane angle; to assess the loss of calcaneal inclination and in evaluating the involvement of the subtalar joint.3 Furthermore most intraarticular fractures involve the posterior articular facet of the subtalar joint, which is the major weight bearing portion of the human heel. *Corresponding author. angle and Gissane’s angles of the calcaneum are important parameters in Calcaneal fracture diagnosis, management and assessment of prognosis.

On the lateral view, the principal landmarks are: the subtalar articular facet – multiple angles (Bo¨ hler angle–Gissane's angle–calcaneal compression angle) were measured and the mean and standard deviation of each angle were calculated. 8 Feb 2018 Then the calcaneal height, Böhler's angle and Gissane's angle were restored and the internal and valgus calcaneus deformity were corrected Keywords: Calcaneum, Bohler's angle, Gissane's angle, Maryland foot score, Locking calcaneal plate.

This meta-analysis showed that there was no significant difference between the two groups regarding the Böhler angle (P = 0.44), Gissane angle (P = 0.06), calcaneal width (P = 0.09) and calcaneal height (P = 0.44) postoperatively and at the last follow-up. Bohler angle and the crucial angle of Gissane are used on the evaluation of calcaneus fractures. However, few authors have described the variation of the angles when the calcaneus is growing. Boehler and Gissane angles are the corner point for calcaneal fractures. Especially, Boehler angle (BA) is the predictor of this fracture type2-4.
Gissane angle, also known as the "critical angle", is an angular measurement made directly inferior to the lateral process of the talus. It is formed by the downward and upward slopes of the calcaneal superior surface. Gissane's angle is also known as the crucial or critical angle and can be used to help determine the presence of a calcaneus fracture on a radiograph. The normal range is 130-145 degrees; An angle > 145 degrees is concerning for calcaneus fracture with involvement of the posterior talar articular surface

Gissane's angle ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. Besides Boehler’s angle, Gissane’s crucial angle (GA) facilitates both to diagnose calcaneal fractures, and to assess the quality of anatomical reduction after fixation. Generally, a reduced GA on a lateral radiograph is indicative of a fracture [10, 20]. Within the relevant literature, normal GAs have been reported in the range of 96–152°.
An angle directly inferior to the lateral process of the talus, formed by a line drawn along the posterior facet of the calcaneus and a line drawn from the anterior process to the sulcus calcaneus, and best seen on a lateral plain film of the calcaneus and hind foot. The crucial angle of Gissane is one of two angles (the The average Gissane angle in our study is 126.79 degrees, whereas in the western population, it is 122.5 degrees. The difference between the western and Indian value in Gissane angle is statistically significant (P < 0.05). 2011-01-10 · In the paediatric study group, the mean Bohler's angle was 35.2 degrees (range 14.3 to 58.1 degrees) and the mean crucial angle of Gissane was 111.3 degrees (range 90.1 to 147 degrees). difference (p>0.05) in the crucial angle of Gissane between the male and female donors (Male: 114.7 degrees compared with Female: 111.9; p>0.05) in the cadaveric study (Table 2). The crucial angle of Gissane was significantly larger in AALTF positive samples than in negative ones of educational bone samples (Graph 1). 2012-12-04 · The Gissane (crucial) angle is formed by two strong cortical struts extending laterally, one along the lateral margin of the posterior facet and the other extending anterior to the beak of the calcaneus.
*Corresponding author. angle and Gissane’s angles of the calcaneum are important parameters in Calcaneal fracture diagnosis, management and assessment of prognosis. Bohler’s and Gissane’s angles are subtended by the Calca-neal bone. Bohler’s angle is also known as Calcaneal angle, Tuber joint angle or Salient angle. It is used for assessing
Bohler angle and the crucial angle of Gissane are used on the evaluation of calcaneus fractures. However, few authors have described the variation of the angles when the calcaneus is growing.

An angle directly inferior to the lateral process of the talus, formed by a line drawn along the posterior facet of the calcaneus and a line drawn from the anterior process to the sulcus calcaneus, and best seen on a lateral plain film of the calcaneus and hind foot.
Gissane's angle ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. The apex of the angle of Gissane is at the location of chronic talar impact with lateral hindfoot impingement, and this is the center of the bony changes, therefore the angle of Gissane, or “calcaneal angle” can be used as a term to identify the calcaneal location of pathology.

The Angle of Gissane, or "Critical Angle", is the angle formed by the downward and upward slopes of the calcaneal superior surface. On a lateral radiograph, an angle of Gissane > 130° suggests fracture of the posterior subtalar joint surface. angle between line from highest point of anterior process to highest point of posterior facet + line tangential to superior edge of tuberosity; measured on lateral view ; normal 20-40° represents collapse of the posterior facet; increased angle of Gissane .
