Objective:To investigate the effects of a novel retrograde tibial nail (RTN) in the treatment of distal tibial fractures.Methods:A retrospective study was conducted in the 11 patients with distal tibial fracture who had been admitted to Department of Traumatic Orthopedics, The Second Affiliated Hospital, Hengyang Medical School from July 2020 to July 2021. There were 5 male and 6 females, aged from 18 to 70 years (average 54.7 years). By the AO/OTA classification, there were 7 extra-articular distal fractures (3 cases of type 43-A1, 3 cases of type 43-A2 and one type 43-A3) and 4 intra-articular fractures (2 cases of type 43-C1 and 2 cases of type 43-C2); by the Gustilo classification, there were 7 closed fractures and 4 open fractures (2 cases of type I and 2 cases of type Ⅱ). All fractures were fixated with a novel RTN. Deformities like distal tibial varus and valgus as well as fracture-related complications were observed after operation while the curative effects evaluated by the ankle-hindfoot score of the American Orthopaedic Foot and Ankle Society (AOFAS).Results:This cohort was followed up for an average of 7.4 months (from 5 to 12 months). All patients obtained clinical union and recovered daily life and work. Radiographic evaluation showed no distal tibial varus or valgus. There were no such complications as postoperative infection, exposure of bone and internal fixation, compartment syndrome, or neurovascular lesion. According to the ankle-hindfoot score of AOFAS, 7 cases were excellent and 4 cases good.Conclusion:This novel retrograde tibial nail may result in good efficacy in the treatment of distal tibial fracture, but its advantages still need further verification.

ObjectiveTo analyze and construct a curriculum framework and content system of the vocational college rehabilitation therapy technology exercise therapy technology course, based on World Health Organization (WHO) International Classification of Functioning, Disability and Health (ICF) and rehabilitation competency framework (RCF). MethodsUsing educational psychology and curriculum theory, and applying the ICF and RCF, the curriculum system for rehabilitation therapy technology curriculum system was constructed. A systematic analysis of the existing exercise therapy technology course content was conducted to identify the core elements related to ICF and RCF. Through the design of course modules, these core elements were integrated into theoretical courses, skills training and practical courses to form a comprehensive curriculum structure. ResultsCombining the ICF and RCF, a curriculum system for rehabilitation therapy technology curriculum system was constructed, covering theoretical courses, skills training and practical courses. This system enabled students to systematically master rehabilitation assessment and treatment techniques and develop clinical decision-making abilities and interdisciplinary collaboration skills. The introduction of the ICF framework allowed students to acquire knowledge, skills and abilities in the field of exercise therapy technology through the course. Developing competency-oriented courses based on RCF framework helped students develop comprehensive professional competencies through learning. ConclusionBy integrating the ICF and RCF, a curriculum for exercise therapy technology course in vocational colleges has been constructed. Based on the ICF framework, the content of the course has been aligned with the bio-psycho-social theory of functioning and health, covering three levels: body function, activity and participation, and environmental factors. The curriculum content should include the analysis, assessment and intervention of these functioning. RCF provides a theoretical structure and methodology for developing competency-oriented courses. When designing the course modules, teaching objectives have been established based on the core competency framework, aiming to develop students' comprehensive professional competence and professionalism through theoretical courses, practical training and clinical internships.
