18 Aug 2020 Important Orthopedic Angles • Calcaneum Fracture: - Bohler's Angle - Gissane's Angle • Cobb's angle (Scoliosis) • Distal End Radius Fracture .

The data on Böhler angle, Gissane angle, calcaneal width, calcaneal height, AOFAS hindfoot scores and complications (including wound edge necrosis, wound infection, deep infection, hematoma and sural nerve injury) were extracted. 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.

Gissane angle

It is better seen on a lateral plain film of the calcaneus and hindfoot. Its normal value is usually between 120° and 145°. 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 Angle [aka *critical angle; critical angle of Gissane], like the Böhler angle, can be used to help determine the presence of a calcaneus fracture on a radiograph. Boehler's angle and the critical angle of Gissane are of limited use in diagnosing calcaneus fractures in the ED Am J Emerg Med .

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.

12 Aug 2020 Gissane's crucial angle (GA) facilitates to diagnose calcaneal fractures, and serves as an indicator of the quality of anatomical reduction after

The sample was mainly composed of two groups: 9 to 12 years of age (39%) and 13 to 16 years of age (31%). In the sample group, the mean Bohler angle was 35.4° ± 5.9° (95% confidence interval [CI]: 23.6°-47.2°) and the mean crucial angle of Gissane was 110.5° ± 7.4° (95% CI: 95.7°-125.3°). Gissane first described this critical or crucial angle in 1947. This angle reveals the angular relationship of the calcaneal facets and parallels the lateral process of the talus on a lateral radiograph (see Fig. 107.2). The cortical density represents the subchondral bone beneath the posterior, anterior, and middle facets.

Cystic lesions at the angle of Gissane occur in 40% to 75% of patients [22, 23]. As with lipomas, patient age is not associated with the presence of a lesion.

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).

METHODS: The electronic literature database of Pubmed, Embase, and Cochrane library were searched in April 2018. The data on Böhler angle, Gissane angle, calcaneal width, calcaneal height, AOFAS hindfoot scores and complications (including wound edge necrosis, wound infection, deep infection, hematoma and sural nerve injury) were extracted.

This angle reveals the angular relationship of the calcaneal facets and parallels the lateral process of the talus on a lateral radiograph (see Fig. 107.2). The cortical density represents the subchondral bone beneath the posterior, anterior, and middle facets. 2019-06-28 · Bohler’s angle was found to be a lot more diagnostically reliable when compared to the critical angle of Gissane (4).

102 - Critical angle of Gissane In 1947, Gissane described his critical angle or crucial angle. He noted a distinct angular cortical platform that parallels the lateral process of the talus on lateral radiographic projection. *This cortical density represents the dense subchondral bone lying beneath the posterior, anterior and middle facets.

The deviation of the angle of Gissane was most pronounced in the cranial direction, with the mean angle decreasing by –8.8° at +30° angular variation. Varying angular obliquity in the caudal and posteroanterior direction hardly affected Gissane's angle. 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.

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.

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. In 1931, Dr. Lorenz Boehler defined this angle as “tuber angle” with a normal range between 30°–35°. BA pre- And the angle of Gissane was significantly smaller in persons with an AALTF, either with or without symptoms (p<0.0001) . In Japan, Hirano and co-workers performed the study to examine the anatomical features of the AALTF of the talus and the opposing calcaneus in aged cadavers (86.5 years old at death: range 70- 102 years).
