Publication Anatomic Variation of Posterior Slope of Tibial Plateau in Adults(Institute of Medicine, 2021) Humagain, Vaskar; Maharjan, Rajram; Paudel, Krishna P; Sigdel, Arun; Sah, Krishna J; Regmi, RabindraABSTRACT Introduction: Posterior tibial slope (PTS) is the tilt bore by the tibial plateau posteriorly and inferiorly relative to the long axis of the shaft of tibia. Mean PTS in each population is imperative to keep within the normal range as possible for good outcome of different surgeries around the knee. Measurement of the PTS using plain radiograph is a cost effective, facile approach and can be done without the use of advanced imaging modalities. Methods: A prospective observational study was done from January to December 2020. Patients presenting to Outpatient Department at National Trauma Center, NAMS with minor knee problems like soft tissue injury, pain, and stiffness were included in the study. PTS was measured via software on a true lateral radiograph of affected knee and its mean value was correlated with parameters, namely, age, sex, BMI, laterality, and race. Results: Mean PTS was 10.350 ±2.030 (range 3-140) in the study size of 185. The mean age of study population was 41.25 ± 15 years (range: 19-73 years). There were 96 males and 89 females in the study. Mean PTS in males was 10.650±2.040 while that in females was 10.030±1.970. The mean BMI of individuals in this study was 25.3 ± 2.61 kg/m2. There was no statistically significant correlation of PTS with age, sex, BMI, laterality, and ethnicity. Conclusion: Posterior tibial slope in adults is not influenced by sex, BMI, side, ethnicity or advancing age.

The purpose of this study is to present the functional outcomes of capitellum fractures after fixation with Herbert screw including the safety and tips of the surgical approach. Methods: This descriptive cross-sectional study was done from December 2014 to November 2019. Ethical approval was taken. The study included 22 capitellum fractures treated by open reduction and internal fixation with Herbert screws either lateral or anterolateral approach. Functional outcomes were assessed with Mayo elbow performance index scores at the latest follow-up visit. Convenient sampling was done. Data entry was done using the Statistical Package for the Social Sciences (version16.0). Results: Out of 22 surgeries, the average time to unite the fracture was 11.13±1.20 weeks (range 9 to 15). The mean range of movement for flexion and extension was 138.41±8.22 degree while the mean supination and pronation range was 161.59±6.79 degree. The average time of follow-up in this series was 37.45±9.43 weeks (range 22 to 58 weeks). Similarly, the mean Mayo elbow performance index score at the latest follow-up was 90.22±8.65 (range 70 to 100). Conclusions: Careful assessment and radiological evaluation, anatomical reduction, and stable fixation with Herbert screws maintaining the minimal damage to the articular cartilage can maximize the functional outcomes and minimize the incidence of complications.
