“…In the statistical comparison with the results of 11 published articles that assessed different populations, it is important to note that a statistically significant difference was observed between the Gissane angle in the Brazilian population and all others available in the literature. Regarding the Böhler angle found in this particular study, no statistically significant difference was observed in the comparison only with the Nigerian (9) , Turkish (10) and Croatian populations (11) . There was a statistically significant difference with the other eight studies evaluated.…”

“…Studies carried out in different parts of the world have evaluated the Böhler angle of their populations, while others have evaluated both Böhler and Gissane angles. The results presented in Table 4 show that there is no statistically significant difference when we compare the Böhler angle found in Brazil with the Nigerian (9) , Turkish (10) , and Croatian (11) populations.…”

Objective: Determine Böhler and Gissane angles in the Brazilian population and compare them with the data available in the literature. Methods: A total of 800 weightbearing lateral radiographs of the calcaneus were evaluated in adult patients of both sexes. The angles were measured using the digital Picture Archiving and Communication System. Results: The sample consisted of 800 patients; 554 (69.2%) were women and 246 (30.8%), men. In the sample evaluated, the Gissane angle is 110.6±11.9, while the Böhler angle is 32.6±6.1. No differences were observed in the angles in terms of the comparison between sex and age. Conclusion: In the Brazilian population, the Gissane angle is 110.6±11.9, while the Böhler angle is 32.6±6.1. There is no statistically significant difference in the comparison between sex and age. Level of Evidence IV; Therapeutic Study; Case Series.

“…More recent studies evaluated a mean (SD) Böhler angle of 36.4 (4.2) degrees in a healthy British study population 32 and 34 (5) degrees in a Croatian study population. 25 We found the Böhler angle of the noninjured feet to have a mean (SD) value of 32.6 (3.8) degrees.…”

Background: Operative treatment of calcaneal fractures using the extensile lateral approach is associated with high rates of soft tissue complications. In the past years, there has been a trend toward less invasive surgical approaches. Percutaneous and arthroscopically assisted calcaneal osteosynthesis (PACO) combines the advantages of visualization of the posterior facet of the subtalar joint with a minimally invasive approach. Methods: We conducted a follow-up of 25 patients with 26 calcaneal fractures (Sanders II and III), treated with PACO with a minimum follow-up of 12 months. The median age was 44 years (range, 21-72) and the follow-up period 15 months (12-33). Our clinical outcomes were the Manchester-Oxford Foot Questionnaire (MOxFQ), the Calcaneus Fracture Scoring System (CFSS), the American Orthopaedic Foot & Ankle Society (AOFAS) Ankle-Hindfoot score, the Short-Form-36 (SF-36), the visual analog scale (VAS) for pain, and the number of complications. Radiographs on follow-up were obtained to evaluate the reduction of the fractures as well as osteoarthritis of the subtalar joint. Results: The median MOxFQ score was 26.6 (0-76.6), the CFSS score 85 (26-100), and the AOFAS score 85 (50-100). The VAS pain score was 0 (0-5.7) at rest and 4.1 (0-8.2) during activity. The Böhler angle improved from a mean (SD) of 3.5 (12.3) degrees preoperatively to 27.7 (10.5) degrees postoperatively. The follow-up radiographs showed subsidence of the fractures and a Böhler angle of 20.3 (12.9) degrees. There were no wound-healing complications. Two patients had additional surgery with screw removal due to prominent hardware. Conclusion: Our results suggest that PACO gives good clinical outcomes and a low risk of complications in selected calcaneal fractures. Prospective long-term studies will be necessary to better document the potential advantages and limitations of this operating technique. Level of Evidence: Level IV, retrospective case series.

“…A large range for normal BA presents in the published research. The mean value of BA is different in different populations . It seems reasonable to use a particular reference value for different ethnic groups, enabling precise treatment for calcaneal fractures.…”

ObjectiveTo determine the value of Böhler's angle (BA) in a group of Chinese people, analyze possible factors that influence it, and compare BA with that in previous literature.MethodsA total of 143 cases, aged from 4 to 79 years, were enrolled in the study, including 64 males and 79 females (79 left feet and 64 right feet). Radiographs were independently measured by six observers. Age, sex, body side, subtalar joint congruity (STJC), and X‐beam obliquity (TT) were recorded. The database was assessed based on intraobserver agreement, data distribution, the randomness of case selection, and the ratio equality of binomial variables. Then, the normal value of BA was established, as well as the correlation between BA and other parameters.ResultsIn the present study, the interobserver reliability of BA, STJC, and TT was excellent. The BA data revealed a normal distribution, and the randomness of case selection was verified for age, sex, and body side. The ratio of sex and body side was equal. Homogeneity of variance was observed when comparing the value of BA between different groups. The value of BA was 31.6° ± 5.19° (range, 20.08°–47.19°), which was not related to age, sex, body side, and minor X‐ray beam obliquity. BA application was not suitable for individuals younger than 10 years. The mean value of BA in this study was not identical with those in previous reports. This demonstrated that BA varies for different races.ConclusionFor Chinese people, 30° to 33° is recommended as the target value of BA for calcaneal fracture reduction, except in children under 10 years of age.
