Objective: The assimilating and converging Kolb learning style were reported to have positive correlation with critical thinking ability in Orthopedic resident. However, the relationship between Kolb learning styles and academic performance remained controversy. The objective of this study is to report the relationship between Kolb learning style and academic performance in Orthopedic residents. Materials and Methods: The causal comparative cross-sectional study on 48 Orthopedic residents of academic year 2020 was conducted. The demographic characteristics of the participants were reviewed. The scores from the multiple choices question (MCQ) in-training examination, the objective structured clinical examination (OSCE) and the global performance rating scale were collected to represent academic performances of each Miller’s pyramid of assessment level. The Kolb learning style inventory were allocated. The statistical analysis was performed and p < 0.05 was considered statistically significant difference. Results: The response rate was 100%. There was no statistically significant difference of MCQ in-training examination, OSCE and global performance rating scale among each learning style as p=0.789, 0.493 and 0.407, respectively. The assimilating and converging styles were the 2 learning styles which had the academic performance scores above the average scores in all assessments. Conclusion: This study could not demonstrate the significant difference of academic performances among Kolb learning style in Orthopedic residents. However, the assimilating and converging style had the consistent scores above average scores in all domains. The Orthopedic learning experience should focus on the development of reflective observation, abstract conceptualization and active experimentation to facilitate effective improvement in academic performance of the residents.

Purpose To retrospective review the clinical outcomes of the modified operative technique using a polyester suture material (Ethibond* Excel) for atlantoaxial transarticular screw fixation and posterior fusion. Methods The retrospective reviews were conducted from 2002 to 2012. The patient's medical record reviews included demographic data, cause of atlantoaxial instability, orthopedic and surgical history, clinical presentation, radiographic finding including plain radiography, complications, operative detail, and outcome of treatment. Fusion of C1-C2 was defined as either graft consolidation or absence of C1-C2 movement on lateral flexion-extension radiograph.Results Twenty-three patients demonstrated clinical and radiographic evidence of atlantoaxial instability (13 men and 10 women, with a mean age of 42 years). Majority of atlantoaxial instability was caused by trauma. Most common clinical symptom was neck pain with or without cervical myelopathy. Bilateral screws were placed in 18 of the 23 patients. Five patients underwent placement of unilateral screws. The 13 patients were inserted by screws with diameter 4.0 mm. The means screw length was 40.33 mm. The means of operative time and estimated blood loss were 3.6 h and 234 ml, respectively. The mean of follow-up duration was 18 months. All 41 screws were positioned satisfactorily in C1 lateral mass. All 23 patients achieved fusion (100 % fusion rate). After a period of follow-up, 9 of the 10 neurological deficit patients had completely recovered. Conclusions We concluded that the atlantoaxial transarticular screw fixation and posterior fusion using polyester cable can be used for C1-2 fusion with a high fusion rate and less complications in various cases.
