That camera has a crucial angle, not only for establishing the defense — giving viewers a broad view of the field — but it is where directors invariably cut whenever a ball is hit fair.
Serial changes in Bohler's angle, the crucial angle, and the calcaneal height were calculated.
Bohler's angle, the crucial angle, and the height of the calcaneus were measured in radiographs as shown in Fig. 3.
Bohler's angle, the crucial angle of Gissane, and calcaneal height in the immediate postoperative period and at the 2-year follow-up were compared.
The average change in the crucial angle was 3.8° ± 1.8° for group A and 3.6° ± 2.1° for group B. This difference was not statistically significant (p = 0.48).
The average change in the crucial angle and the average change in calcaneal height were not statistically significant for either group.
Comparison of the immediate-postoperative radiological results and those at the 2-year follow-up showed changes in Bohler's angle, the crucial angle, and the height of the calcaneus (Tables 4 and 5).
We compared the infection rates, times to full weight-bearing, reduction of the posterior facet, subtalar fusion rates, reduction of Bohler's angle, changes in the crucial angle, changes in calcaneal height, and efficacy outcomes between the two groups.
The joint-depression type, which is the more frequent of the two, occurs when the secondary fracture line begins at the crucial angle, extends posteriorly, but deviates dorsally, to exit the bone just posterior to the posterior articular facet.
