Functional and Radiological Outcomes of Surgically Treated Coxa-vara in Children.

BACKGROUND: Coxa vara is a condition in which the neck-shaft angle of the femur decreases below its normal value (<110 degrees) based on age. The deformity can be primarily caused by a congenital defect of the femoral neck cartilage or by secondary causes related to skeletal dysplasia, trauma, infection, and pathological bone disorders. The surgical treatment aims to restore the normal anatomy, thereby improving the mechanics and function of the hip joint. Generally, the HE angles should be corrected to <35 to 40 degrees, converting the shear forces into compressive forces. Our study aims to report the surgical outcome of coxa vara with various pathologies using radiographic measurement and functional scoring. METHODS: Thirty-eight hips in 28 patients who underwent surgery for treatment of coxa-vara from 2013 to 2022 were included. Radiographic parameters like Hilgenreiner-epiphyseal angle and neck-shaft angle were assessed preoperatively and at the latest follow-up. Harris hip score was used for functional outcome. RESULTS: The mean age was 11.13 (5 to 18). The average follow-up was 48 (ranging from 24 to 96) months. The mean preoperative neck-shaft angle was 82 degrees, and the Hilgenreiner-epiphyseal angle was 71 degrees. At the latest follow-up, the mean neck-shaft angle was 127 degrees, and the Hilgenreiner-epiphyseal angle was 33 ( P <0.001). The Harris hip score improved from 63 preoperatively to 92 at the latest follow-up ( P <0.001). There was no recurrence of deformities at the mean follow-up of 37.87 months. Four complications occurred with k-wire fixation in whom revalgus osteotomy was done. CONCLUSIONS: Surgical correction of coxa vara in various pathologies can be done successfully with the Hilgenreiner-epiphyseal angle corrected to ≤ 35 degrees or the neck shaft angle corrected to >110 degrees to prevent deformity recurrence. The majority of the patients reported improvement in hip function. However, a longer-term follow-up is required to determine further outcomes regarding the recurrence of the deformity.

Open segmental tibial bone defects treated with Ilizarov frame: a radiological and functional outcome study with average ten year follow-up.

PURPOSE: Surgical reconstruction of large post-traumatic tibial bone and soft tissue defects following high-energy trauma presents a significant challenge for orthopaedic surgeons. This study aimed to evaluate the functional and radiological outcomes of large post-traumatic tibial bone and soft tissue defects managed by single or double-level bone transport using the Ilizarov technique. MATERIAL & METHODS: 13 patients who underwent treatment for large tibial bone defects (Gustillo IIIa, IIIb, IIIc) along with soft tissue defects with Ilizarov from 2010 to 2020 A.D were included. ASAMI functional and radiological outcomes were assessed at the final follow-up to report the outcome. RESULTS: The mean age was 27.38 (18-48). An average bone defect was 7.69 cm (5-13 cm). Based upon the Gustillo-Anderson classification (GA), 2 (15%) of them were GA - 3 A, 7 (54%) were GA - 3B, and 4 (31%) were GA - 3 C. The average time of distraction was 11.76 weeks (8-16). The average time for the union was 37 weeks (27-48 weeks). The average bone lengthening was 7.69 cm (5-13 cm). The mean final leg length discrepancy (LLD) at the final follow-up was 1.96 cm (0-4 cm). The primary union was achieved in eight cases, and five required bone grafting at the docking site. Using the ASAMI (Association for the Study of the Method of Ilizarov) scoring system, the functional results were excellent in six and good in seven cases, while the bony results were excellent in eight, good in four and fair in one case. CONCLUSION: Good to excellent functional and radiological scores (ASAMI) can be expected when using the Ilizarov frame for simultaneous treatment of the large tibial bone and soft tissue defect when this method is applied with correct principles.

Tobacco Use and Its Associated Factors among Undergraduate Public Health Students in Kathmandu Valley, Nepal.

Background: Despite the crucial role of public health students in tobacco control, there is a paucity of information regarding tobacco use among this population in Nepal. This study aims to assess the prevalence of tobacco use among undergraduate public health students in Kathmandu valley, Nepal. Methods: A web-based survey was conducted among 386 undergraduate public health students in Kathmandu valley, Nepal, using the Global Health Professions Student Survey (GHPSS) questionnaire. Associated factors were examined using multivariate logistic regression analyses at the level of significance of 0.05. Results: A total of 16.8% of students were current cigarette smokers, 39.9% had ever smoked cigarettes, and 62.2% had smoked their first cigarettes during adolescence. Among the participants, 11.7% currently used other tobacco products. Male students (aOR: 15.4; 95% CI: 4.9-47.8), students with higher age (aOR: 2.4; 95% CI: 1.0-5.4), students belonging to non-Brahmin/Chhetri ethnic group (aOR: 2.3; 95% CI: 1.2-4.4), and those staying without family (aOR: 2.0; 95% CI: 1.1-5.0) had higher odds of being current smoker. Similarly, students with a parental history of tobacco use (aOR: 2.4; 95% CI: 1.3-5.0) and friends with smoking habits (aOR: 7.9; 95% CI: 2.3-27.0) were more likely to be a current smoker. Conclusion: There is a notable prevalence of tobacco use among public health students in Kathmandu valley, Nepal. Concerned stakeholders should work jointly to implement a cessation program to discourage tobacco use among these populations who have a potential role in educating communities about the hazards of tobacco smoking, tobacco use prevention, and control.
