Boehler's angle and the critical angle of Gissane are of limited use in diagnosing calcaneus fractures in the ED Am J Emerg Med . 2006 Jul;24(4):423-7. doi: 10.1016/j.ajem.2005.12.013. 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.
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. The average Gissane angle in our study is 126.79 degrees, whereas in the western population, it is 122.5 degrees. In this study, Bohler angle and the crucial angle of Gissane in paediatric population were measured using lateral foot radiographs of 429 patients, from 0 to 16 years of age. The control group was composed of 70 adult patients.
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 .

Table 1: Bohler’s and Gissane’s angles in the study population Number of ankles measured Mean SD Bohler's angle is the angle formed between these two lines. A normal Bohler's angle is approximately 25 to 40 degrees.

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.
2015-12-01 · In summary, like other radiographic measurements, Böhler's angle and the crucial angle of Gissane possess limitations in reliability. Using trained observers for measurement, we show that even in optimal settings, disagreement in X-ray interpretation is common. 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. In this study, Bohler angle and the crucial angle of Gissane in paediatric population were measured using lateral foot radiographs of 429 patients, from 0 to 16 years of age. In the CRPF group, the Böhler and Gissane angles were found to be restored better than in the CRP group, although this was not statistically significant (p=0.421, p=0.554, p=0.751, p=0.698). In functional evaluations with the AOFAS and MFS scales, better scores were calculated in the CRPF group and a statistically significant difference was found (p=0.017, p=0.023).

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°.
