Objective To evaluate the feasibility and significance of problem-based learning (PBL) in orthopedic internship. Methods A total of 315 students in grade 2002 were involved in PBL during their internship in the Department of Orthopedics at the First Affiliated Hospital of China Medical University, Shenyang, China. Teaching effectiveness was evaluated with a questionnaire and an ability examination. The results of PBL teaching during different semesters were compared, and the feasibil ity and significance of PBL were analyzed. Results Students who participated in PBL were in a dominant position and were more active in the learning process. The PBL pattern could improve students’ ability to identify, analyze and solve problems, and also contribute to fostering and enhancing their clinical thinking. This could help them solve the problems that emerged from the theory curriculum.Conclusions The PBL pattern used in the orthopedics internship has advantages and practical significance, which are applicable in modern medical teaching practice.
ObjectiveTo explore the application of clinical pathway in patients undergoing orthopedic day surgery.MethodsPatients who were scheduled for orthopedic treatment at Day Surgery Department of the Second Hospital of Shanxi Medical University from May to October 2020 were selected as the clinical pathway group, and all of them were managed by clinical pathway. Patients who were scheduled for orthopedic treatment at Day Surgery Department of the Second Hospital of Shanxi Medical University from May to October 2019 were selected as the routine group, and all of them were managed by conventional clinical methods. The general conditions of patients, physicians’ work efficiency, medical costs and medical quality were compared between the two groups.ResultsThe clinical pathway group included 246 patients, and the routine group included 391 patients. There was no significant difference in gender, age or disease distribution between the two groups (P>0.05). Compared with the routine group, the clinical pathway group had obvious advantages in terms of average time spent by a physician in issuing a medical order each time [(5.64±3.29) vs. (2.12±1.05) min], average number of revisions per physician’s order (1.40±0.24 vs. 0.38±0.19), rate of filing medical records within 3 days (90.28% vs. 97.97%), hospital costs [(7462.10±1035.01) vs. (6252.52±1189.05) yuan], drug costs [(652.21±88.53) vs. (437.17±108.20) yuan], length of stay [(1.23±1.04) vs. (1.02±0.18) d] and delayed discharge rate (7.93% vs. 2.03%), with statistically significant differences (P<0.05). There was no significant difference between the two groups in terms of unplanned reoperation rate, unplanned rehospitalization rate, or patient satisfaction (P>0.05).ConclusionCompared with routine clinical management, clinical pathway management can improve work efficiency, reduce medical cost and improve medical quality more effectively in the implementation of orthopedic day surgery, which has very positive effects and is worthy of promotion and application.
ObjectiveTo review the current status and progress of locking plate for the treatment of distal femoral comminuted fractures.MethodsThe related literature was extensively reviewed to summarize the current status and progress in the treatment of distal femoral comminuted fracture with locking plate from four aspects: the current treatment situation, the shortcomings of locking plate and countermeasures, the progress of locking technology, locking plate and digital orthopedic technology.ResultsTreatment of distal femoral comminuted fractures is challenging. Locking plates, the most commonly used fixation for distal femoral comminuted fractures, still face a high rate of treatment failure. Double plates can improve the mechanical stability of comminuted fractures, but specific quantitative criteria are still lacking for when to choose double plates for fixation. The far cortial locking screw has shown good application value in improving the micro-movement and promoting the growth of callus. The biphasic plating is a development of the traditional locking plate, but needs further clinical examination. As an auxiliary means, digital orthopedic technology shows a good application prospect.ConclusionThe inherent defect of locking plate is a factor that affects the prognosis of distal femoral comminuted fracture. The optimization of locking technology combined with digital orthopedic technology is expected to reduce the failure rate of treatment of distal femoral comminuted fracture.

Objective To explore the advantages and effectiveness of the independently developed intelligent orthopedic robot-assisted distal locking of femoral intramedullary nails. Methods Thirty-two adult cadaveric femur specimens were randomly divided into two groups, with 16 specimens in each group. The experimental group used the intelligent orthopedic robot to assist in the distal locking of femoral intramedullary nail holes, while the control group used the traditional method of manual locking under X-ray fluoroscopy. The locking time, fluoroscopy times, and the success rate of first locking were recorded and compared between the two groups. Results The locking time of the experimental group was (273.94±38.67) seconds, which was shorter than that of the control group [(378.38±152.72) seconds], and number of fluoroscopies was (4.56±0.81) times, which was less than that of the control group [(8.00±3.98) times]. The differences were significant [MD=73.054 (−37.187, 85.813), P=0.049; MD=1.969 (−1.437, 2.563), P=0.002]. The first locking success rate of the experimental group was 100% (16/16), which was significantly higher than that of the control group (68.75%, 11/16) (P=0.043). ConclusionThe efficiency of distal locking of femoral intramedullary nails assisted by the intelligent orthopedic robot is significantly higher than that of the traditional manual locking method under fluoroscopy, as it can markedly reduce the time required for distal locking of femoral intramedullary nails, decrease intraoperative radiation exposure, and increase the success rate of locking.
Objective To investigate the early diagnosis of lower l imb deep vein thrombosis (DVT) after major orthopedic surgeries. Methods From October 2005 to June 2009, color doppler sonography and hemorheology detection were carried out for 62 cases undergoing first total hip arthroplasty (THA), 14 cases undergoing total knee arthroplasty (TKA), and 86 cases undergoing hip fractures surgery (HFS) before operation and 1, 7, 14 days after operation. The plasma D-dimerlevels of the DVT were also examined for the THA patients before operation and 3 days after operation. Of all cases, therewere 89 males and 73 females, aged from 34 to 74 years (51.5 years on average). After operation, all the patients were treated with the regular low molecular weight heparin sodium against DVT. Results After operation, 17 cases (10.5%) developed DVT, including 8 THA cases, 1 TKA case, and 8 HFS cases. Preoperative color doppler sonography showed no abnormal echo, normal b blood flow signal, and normal periodical variation in vein blood flow without regurgitation. Postoperative examinations showed that the vascular occlusion of common femoral vein and popl iteal vein occurred in DVT patients. There were significant differences (P lt; 0.05) in whole blood viscosity between patients with DVT and without DVT after 1, 14 days and no significant difference (P gt; 0.05) before operation and 7 days after operation. There was no significant difference (P gt; 0.05) in plasma viscosity and erythrocyte aggregation index, between patients with DVT and without DVT pre- and postoperation. There was significant difference (P lt; 0.05) in erythrocyte deformation index between patients with DVT and without DVT 14 days after operation. The preoperative plasma D-dimer levels of patients with DVT and without DVT were (372.00 ± 148.62) ng/mL and (369.00 ± 141.03) ng/mL, respectively, showing no significant difference (P gt; 0.05); the 3 days postoperatively levels were (574.00 ± 217.29) ng/mL and (391.00 ± 120.16) ng/mL, respectively, showing significant difference (P lt; 0.05). Conclusion Color doppler sonography in combination of hemorheology and plasma D-dimer examination can be beneficial for the early diagnosis of DVT in major orthopedic surgeries.
Objective To develope a modified surgical lavage tube to improve the efficacy of the treatment of orthopaedic postoperative infection. Methods A retrospective analysis was performed on 126 patients who received the pulsed lavage therapy with side-hole double valve lavage tube between March 2005 and March 2010. There were 98 males and28 females, aged 19-63 years (mean, 35 years). The infected sites included femur in 61 cases, tibiofibula in 46 cases, humerus in 12 cases, and patella in 7 cases. The lavage tube obstruction and defluvium, secondary infection of drainage opening, and wound heal ing were observed during treatment. Results No lavage tube defluvium occured during the lavage in all cases. Lavage tube obstruction occurred in 68 cases, edema at the peri pheral tissue was caused by obstruction in 9 cases; secondary infection at the lavage and drainage opening in 10 cases, which were cured after corresponding treatment. All cases achieved wound healing by first intention within 2 weeks. Lavage tube and drainage opening were closed within 1 month. All patients were followed up 1-5 years (mean, 18 months) with no recurrence. Conclusion Pulsed lavage therapy with side-hole double valve lavage tube can obviously improve the efficacy of the treatment of orthopaedic postoperative infection, so it is an effective modification to convention lavage.
