Abstract:
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. The control group was composed of 70 adult patients. The sample had a mean Bohler angle of 35.4° ± 5.9° and a mean crucial angle of Gissane of 110.5° ± 7.4°. The greater mean difference was identified for Bohler angle (8°) in the age group of 5 to 8 years (39.6° ± 5.7°) and for the crucial angle of Gissane (5°-6°) in the age group of 0 to 4 years (115.8° ± 7.3) ( P < .05). The influence of the ossification centres on the geometry of the calcaneus across age groups makes Bohler angle and the crucial angle of Gissane higher in young children. The increase in Bohler angle points out the relative development of the posterior facet in young children and the importance of the reconstruction of the posterior facet height in the intra-articular calcaneus fractures. Level of Evidence: Diagnostic study; Level III.

Abstract:
Objective: To demonstrate the efficacy of locking plate osteosynthesis performed by an L-shaped lateral approach in patients with Sanders type III and IV intra-articular calcaneal fractures with posterior facet displacement. Methods: Fifty-three patients with Sanders type III or IV unilateral calcaneal fractures treated with locking plates and additional bone grafting were included in the study. Böhler and Gissane angles, and heel height values were measured on the radiological examinations. Clinical results of the patients were evaluated using the American Orthopaedic Foot and Ankle Society and Maryland evaluation criteria. The presence of arthrosis was investigated with Broden’s view. Preoperative and postoperative values were evaluated. Results: The mean Gissane angle was 119.32°, the mean Böhler angle was 9.47° and the mean heel height was 40.82 mm on radiographs at initial presentation of the patients. The mean Gissane angle was 114.63°, the mean Böhler angle was 23.33° and the mean heel height was 47.84 mm on the early postoperative radiographs of the patients. In patients, a mean 4.69° recovery was achieved in the Gissane angle, 13.86° in Böhler angle and 7.02 mm in heel height. On the most recent follow-up, Böhler angle was 21.49°, Gissane was 114.88° and the mean heel height was 46.95 mm. The mean American Orthopaedic Foot and Ankle Society score and Maryland score were 86.91 and 86.53, respectively, on the last follow-up. Conclusion: Internal fixation and grephonage using low-profile locking plates provides good functional results to patients since it facilitates anatomic restoration of the subtalar joint and correction of calcaneal height, width and varus/valgus heel.

Abstract:
Objective: To evaluate the inter-rater reliability and intra-class correlation coefficients (ICC) of Böhler’s angle and the critical angle of Gissane in calcaneal fractures, stratified by severity and by the Essex-Lopresti and Sanders classifications. Methods: Retrospective study of radiographs obtained from 97 patients: 67 with calcaneal fractures and 30 with normal lateral radiographs (used as a control group). Böhler’s angle and the angle of Gissane were measured by six raters: two orthopedic surgery residents, two musculoskeletal radiologists, a foot and ankle surgery fellow, and a senior consultant in foot surgery. Statistical analysis of inter-rater reliability was performed for the two angles, in the sample overall and stratified by the different radiographic and CT subtypes of calcaneal fractures. Results: For the angle of Gissane, the ICC was at best 0.400 (95% CI: 0.250 to 0.581) for normal radiographs, with poor agreement across all classifications and severity stratifications. For Böhler’s angle, the ICC values indicated weak to moderate agreement, with the best reproducibility obtained for the overall sample (0.740; 95% CI: 0.673 to 0.801). In Sanders type 1 fractures, the ICC was 0.704 (95% CI: 0.397 to 0.940), and in Sanders type 2 fractures, 0.762 (95% CI: 0.634 to 0.870). Conclusion: Böhler’s angle is more reproducible than the critical angle of Gissane, with greater inter-rater reliability among fractures deemed less severe on the Sanders classification, although the overall ICC ranged from weak to moderate at best.

Abstract:
ABSTRACT Background: To evaluate the evolution of patients with intra-articular fracture of the calcaneus submitted to surgical treatment. Methods: This observational, prospective cohort study included patients aged 18-65 years with intra-articular calcaneal fractures treated surgically using the lateral approach technique and blocked calcaneal plaque. Image exams assessed Bohler and Gissane angles and joint congruence. Physical examinations measured ankle joint range of motion (ROM) and utilized the AOFAS and FAOS scales. Data were collected 2 and 6 months postoperatively. Results: Sixteen patients with a mean age of 45.2 years participated. Average Gissane and Bohler angles were 127.2 ± 10.9 and 24 ± 13.9, respectively. The AOFAS questionnaire score was 43.69 ± 17.59. FAOS scores for pain, other symptoms, daily living activity, sports and recreation, and quality of life were 15.69 ± 9.99; 10.56 ± 4.80; 25.00 ± 15.91; 13.63 ± 6.09; and 8.88 ± 4.82, respectively. A positive correlation was found between AOFAS total score and dorsiflexion (rs = 0.526; p = 0.036). Conclusions: Adequate dorsiflexion range of motion is related to higher AOFAS scores, and an inverse correlation exists between Bohler’s angle and pain, daily life activity, and other FAOS symptoms.

Abstract:
Introduction: Calcaneal fractures are a common tarsal injury, which remains a diagnostic and therapeutic challenge. Although tomography has optimized their evaluation, the measurement of Böhler and Gissane angles on conventional radiographs remains essential for initial diagnosis and follow-up. The normal values of these angles may vary according to the population, the present study is looking for reference values in the Colombian population. Methodology: A descriptive cross-sectional study was performed in an imaging center in Barranquilla, Colombia. Lateral ankle radiographs of patients older than 18 years without bone alterations were analyzed. Böhler and Gissane angles were measured by two investigators independently on two different occasions. Measures of central tendency and dispersion were calculated. Student's t-tests were applied to evaluate differences by sex, laterality and age group. Results: 240 radiographs of 189 patients were evaluated. The mean Böhler angle was 31.36° ± 6.03 and the mean Gissane angle was 117.23° ± 7.74. No statistically significant differences were observed according to sex, laterality or age group (p > 0.05). Discussion: The values obtained are similar to those reported in Latin American studies, although slightly lower than the classic ranges described in North American and European populations. These findings reinforce the importance of having local reference values for radiographic evaluation of the calcaneus. Conclusions: The Böhler and Gissane angles in the Colombian population present values comparable to those of other Latin American populations. It is suggested to use these values as a reference in local clinical practice for a more accurate diagnosis

Abstract:
Objective: The aim of this study is to test the hypothesis that patients with calcaneal fractures who are surgically treated and have Böhler and Gissane angles restored to normal have a faster return to work than patients without restoration of these angles. Calcaneal fractures represent 1-2% of all fractures, and approximately 75% of these are articular, indicating surgical treatment. Joint involvement results in functional limitation and can lead to late complications such as chronic pain, subtalar arthrosis, difficulty walking, and deformities. Methods: Lateral radiographs of the calcaneus of 44 patients who underwent surgical treatment for calcaneal fracture during the period from 2014 to 2016 were analysed to measure the Böhler and Gissane angles and to evaluate the association of their restoration to normal with the time to return to work. Results: Among the patients, 70.2% presented restoration of the Böhler angle and 44.7% presented restoration of the Gissane angle with surgery. The mean time away from work was 8.38 months. A total of 76.6% of patients returned to the same function. Patients who had good fracture reduction had a shorter time to return to work, but this result was not statistically significant. Conclusion: Surgical restoration of angles can positively influence the functional outcomes of patients, but this is not the only variable and thus should not be exclusively used to analyse the functional outcome and time to return to work of patients.

Abstract:
Objective This study was performed to analyze the outcomes of calcaneal fractures using a minimally invasive internal fixation method with a thin plate and bone grafting. Methods This retrospective analysis included 21 patients treated using our minimally invasive approach. The outcome measures were the change in the Bohler and Gissane angles and the calcaneus width after fixation. The clinical outcomes were evaluated by the Maryland foot scoring system and assessment of soft tissue complications. Results The follow-up time was 12 to 18 months. The Bohler angle, Gissane angle, and width of the calcaneus were significantly different between the preoperative and postoperative periods. The rate of excellent and good outcomes was 85.7% according to the Maryland foot scoring system. The incidence of soft tissue complications was 14.3%. Conclusion Treatment of calcaneal fractures using a minimally invasive internal fixation method with a plate and bone grafting provides good to excellent clinical outcomes with few soft tissue complications.

Abstract:
Objective To compare the clinical efficacy of sinus tarsi incision and traditional operation in the treatment of calcaneal fractures. Methods A total of 46 patients with calcaneal fracture admitted to Jianli People's Hospital from June 2020 to January 2022 were included, including 37 males and 9 females. 23 patients in the control group were treated with "L" incision, and 23 patients in the experimental group were treated with tarsal sinus incision. The length of hospitalization, operation time an, surgical incision length, grainage volume, complication of the two groups were recorded respectively. The results of Bohler Angle and Gissane Angle were measured before and after operation. Results The operation time of the test group is shorter than that of the control group. Compared with the operation time of the two groups, the difference is statistically significant (P<0.01). The postoperative drainage flow of the test group is less than that of the control group. The contrast difference between the two groups in the operation area is statistically significant (P<0.01), and the length of the surgical incision in the test group is shorter than that of the control group. The length of the surgical incision is statistically significant compared with the length of the two groups (P<0.01). The number of days of hospitalization in the test group is shorter than the number of days in the control group, but there is no statistical significance (P>0.05). The patient's pre-operative Bohler angle measurement result and the Gissane angle measurement knot. The difference has no statistical significance (P>0.05). Bohler Angle in both control group and experimental group was significantly higher after surgery than before surgery (P < 0.01), and Gissane Angle was significantly lower after surgery than before surgery (P < 0.01). However, there was no significant difference in Bohler Angle and Gissane Angle between the two groups before and after surgery (P > 0.05). The complication rate of control group was higher than that of experimental group, but there was no significant difference between the two groups (χ2=0.357, P > 0.05). Conclusion For Sanders II and III calcaneal fractures, the "L" incision is like the sinus tarsi incision. However, the incision of tarsal sinus has the advantages of small trauma, short operation time and good recovery of patients.
