Objective To discuss the curative effect of computer assisted pre-operation plan (CAPP) in treating the geriatric intertrochanteric femoral fracture.Methods The data of intertrochanteric fractures treated with PFNA-Ⅱ between March 2012 and June 2015 were retrospectively analyzed.They were divided into two groups by preoperative design.One group was the CAPP group consisting of 53 patients with a mean age of 75.3 years (range,60-92 years).According to the Evans Classification,there were 12 Evans type Ⅰb,9 Evans type Ⅰc,15 Evans type Ⅰd and 17 Evans type Ⅱ fractures.The other group was the non-CAPP group consisting of 74 patients with a mean age of 76.6 years (range,62-95 years).There were 18 Evans type Ⅰb,15 Evans type Ⅰc,20 Evans type Ⅰd and 21 Evans type Ⅱ fractures.Operation time,intraoperative blood loss,times of fluoroscopy during operation and days of hospital stay were compared.The hip joint function was evaluated by Harris score at the final follow-up.Results The CAPP meanly cost 24.7 min.The consistency of the surgery and CAPP was up to 100％.In the CAPP group,the average operation time was 46.8±6.5 min;the average times of fluoroscopy during operation were 12.0±2.3 times;and the average blood loss was 154.4±27.6 ml.In the non-CAPP group,the average operation time was 57.8±10.3 min;the average times of fluoroscopy during operation was 20.9±3.2;and the average blood loss was 235.0±65.8 ml.All above data in the CAPP group were significantly lower than those in the non-CAPP group.The mean days of hospital stay were 13.9±1.3 days in the CAPP group and 14.3±1.4 days in non-CAPP group.The days of hospital stay had no significant difference between the two groups.Forty-five patients with an average follow-up period of 18.3 months were reviewed in the CAPP group.Fifty patients were followed up with an average period of 19.2 months in the non-CAPP group.At the final follow-up,the average Harris score was 88.6±2.8 points (range,84-96 points) in the CAPP group and 87.5±3.2 points (range,80-95 points) in the non-CAPP group.Conclusion CAPP system is convenient and efficient.It can facilitate the treatment of intertrochanteric fracture effectively.

Objective: evaluate the efficacy of a single medial locking plate and lag screws based on computer-assisted pre-operation plan (CAPP) for the treatment of pilon fractures. Methods: Between 2013 and 2016, data of 27 patients with pilon fractures who were treated using a single medial locking and lag screws based on CAPP were retrospectively analyzed. All the cas-es were AO/OTA 43-C type pilon fractures. According to the Rüedi-Allgöwer classification, there were 5 cases of type Ⅱ and 22 cases of type Ⅲ. Among 27 patients, 19 patients had fibula fracture. CAPP was performed for all fractures, including simulated re-duction, virtual surgery, and implantation of internal fixation. The time of CAPP, intraoperative realization of preoperative plan, op-eration time, intraoperative blood loss, and pre- and post-operative range of motion of ankle were recorded. Functional outcomes at final follow up were assessed using American Orthopedic Foot and Ankle Society (AOFAS) ankle hindfoot scale, visual analogue scale (VAS). Results: The mean time of CAPP was 25.8 minutes (range, 14-30 minutes). The average operating time was 138.5 minutes. The average intraoperative blood loss was 225.9 ml. All the twenty-seven patients were followed up for an average period of 18.6 months. The average AOFAS score, VAS score at the final follow-up was 82.9, 2.7 points respectively, which was signifi-cantly improved compared with those before operation (t=-19.358, 7.720; all P< 0.001). Conclusion CAPP system is convenient and efficient, which can facilitate the treatment of type C pilon fractures with a single medial locking plate and lag screws. In addi-tion, satisfactory clinical outcomes can be obtained.

Objective:To explore the teaching effect of magnetic on-demand teaching mode in nursing interns of neurology department.Methods:Forty-two nursing students who practiced in Neurology Department of Haikou People's Hospital from July 2019 to December 2019 were selected as the control group, and 44 nursing students who practiced from January 2020 to June 2020 were selected as the study group. The traditional teaching mode was adopted in the control group, while the magnetic on-demand teaching mode was adopted in the study group. The scores of theory and skill examination after teaching, nurses' core competence (evaluated by nurse core competence scale) before and after teaching, active learning rate and incidence of nursing errors during teaching and satisfaction with teaching were compared between the two groups. SPSS 25.0 was used for t test and chi-square test. Results:After teaching, the scores of theory and skills in the study group were significantly higher than those in the control group ( P<0.05). After teaching, the scores of core competence of nurses in the two groups were higher than before, and the scores of core competence of nurses in the study group were higher ( P<0.05). During the teaching period, the active learning rate of the study group was higher than that of the control group ( P<0.05), and the incidence rate of nursing errors was lower than that of the control group ( P<0.05). The satisfaction of all kinds of teaching in the study group was higher than that in the control group, with statistically significant differences. Conclusion:In the clinical teaching of nursing interns in neurology department, the magnetic on-demand teaching mode can significantly enhance the mastery of nursing theory and skills, improve the core competence of nurses, improve the active learning rate and teaching satisfaction, and reduce the occurrence of nursing errors.

TSCI have dyskinesia and sensory disturbance that can cause various life-threaten complications. The patients with traumatic spinal cord injury (TSCI), seriously affecting the quality of life of patients. Based on the epidemiology of TSCI and domestic and foreign literatures as well as expert investigations, this expert consensus reviews the definition, injury classification, rehabilitation assessment, rehabilitation strategies and rehabilitation measures of TSCI so as to provide early standardized rehabilitation treatment methods for TSCI.

With the spread of novel coronavirus pneumonia (NCP) in December 2019, the management and rehabilitation of elderly patients with hip fractures and protection of medical staff face new challenges, and need to be adjusted appropriately under this very circumstances. Hip fractures in the elderly account for more than half of osteoporotic fractures. Expert group formulate this consensus so as to make better decision against this epidemic and protect patients' families and medical staff. This consensus elaborates not only epidemic condition of NCP, but also general principles of medical admission, treatment and protection for both medical staff and patients, in order to provide some reference and promote the standardization of clinical diagnosis and treatment of elderly patients with hip fractures under the condition of NCP.
