Objective To investigate the epidemiological characteristics of the in-patients with femoral supracondylar fracture in the Third Hospital of Hebei Medical University from 2009 through 2018.Methods The medical imaging computer archiving and transmission system and the medical record inquiry system were used to collect the data of all the in-patients with femoral supracondylar fracture who had been treated from January 2009 through December 2018 in The Third Hospital of Hebei Medical University.Their gender and age distribution,basic sociological data and cause of injury were characterized.The in-patients from January 2009 to December 2013 were assigned into group A while those from January 2004 to December 2018 into group B.The 2 groups were compared to find out the epidemiological characteristics and trends of the in-patients with femoral supracondylar fracture in the 10 years.Results Of the 508 in-patients with femoral supracondylar fracture,279 (54.9％) were male and 229 (45.1％) female.Their age ranged from 1 to 94 years,averaging 44.3 years.The age group from 41 to 50 years accounted for the largest proportion (104 cases,23.9％).In males,the age group from 41 to 50 years accounted for the largest proportion (33.3％,80/279);in females,the age group from 51 to 60 years the largest proportion (30.3 ％,59/229).The proportion of females in the in-patients under 50 years of age (37.1％) was significantly lower than that (62.9％) in the in-patients over 50 years of age (P ＜ 0.05).According to the AO classification,there were 193 cases (38％) of type 33-A1,117 ones (23％) of type 33-A2 and 198 ones (39％) of type 33-A3.There were 270 farmers (53.1％),164 workers (32.4％) and 74 students (14.5％).Most injuries were caused by high energy (56.5％).The age of in-patients with low-energy injury (50.5 ±20.7 years) was significantly higher than that of in-patients with high-energy injury (39.5 ± 19.6 years) (P ＜0.05).The proportions of urban residents (30.0％),patients with low energy injury (37.9％) and type 33-A1 fractures (23.9％) in group A were significantly lower than in group B (43.3％,46.9％ and 32.3％,respectively) (P ＜ 0.05);the age of group A (41.9 ± 21.8 years) was significantly younger than that of group B (45.9 ± 19.9 years) (P ＜0.05);type 33-A3 fractures in group A (46.5％) were significantly more than in group B (36.3％) (P ＜0.05).Conclusions Femoral supracondylar fractures were more common in farmers.Most of the fractures were type 33-A3.The fractures were common in males from 41 to 50 years old and in females from 51 to 60 years old.There were more males than females in the junior patients but more females than males in senior patients.There were more young patients in complex fractures but there were more old patients in simple fractures and there were more very old patients in low-energy injuries.In the past 10 years,the patients with femoral supracondylar fracture increased year by year.Compared with the first 5 years,the late 5 years witnessed significant increases in age of patients and proportions of low-energy injury and simple fracture.

Objective To analyze the epidemiological characteristics of all the patients with tibial plateau fracture admitted to the Third Hospital of Hebei Medical University in the past 10 years.Methods The picture achieving and communication system was used to collect the general information and disease-related information from the hospitalized patients with tibial plateau fracture who met the inclusion and exclusion criteria from January 1,2009 to December 31,2018.The patients from January 1,2009 to December 31,2013 were assigned into group A while those from January 1,2014 to December 31,2018 into group B.The 2 groups were compared to find out the epidemiological characteristics and trends of tibial plateau fractures in the past 10 years in gender,age,occupation,injury cause and Schatzker classification.Results A total of 1,936 patients with tibial plateau fracture were included in the study,including 1,352 males and 584 femaleswith a male to female ratio of 2.32∶ 1.The peak age ranged from 50 to 59 years,with 40 to 49 years for males and 50 to 59 for females.There were 793 cases in group A (a male to female ratio of 1.89∶1) and 1,143 ones in group B (2.69∶1),showing a significant difference between the 2 groups in the male to female ratio (P ＜ 0.05).The peak age ranged from 40 to 49 years (25.09％,199/793) in group A and from 50 to 59 years (23.27％,266/1,143)in group B.There were significant differences between the 2 groups in the constituent ratios of age groups from ≥50 years (P ＜ 0.05).Physical workers accounted for the highest proportion in group A (57.12％,453/793) and group B (52.58％,601/1,143).There were significant differences between the 2 groups in the constituent ratios of occupations (P ＜ 0.05).In all the 1,837 patients with a definite injury cause,the fall and indoor activity accounted for the highest proportion(41.92％,770/1,837),the traffic accident(33.25％,248/769) in group A did and the fall and indoor activity(48.88％,522/1,068) in group B did too.There were significant differences between the 2 groups in the injury causes (P ＜ 0.05).Of all the 1,658 patients with X-ray films available,by the Schatzker classification,types Ⅱ and Ⅵ were the most common.Type Ⅵ accounted for the highest proportion in group A (33.25％,248/769) while type Ⅱ did in group B (48.88％,522/1,068).There were significant differences between the 2 groups in the proportions of Schatzker types (P ＜ 0.05).Conclusions The tibial plateau fractures admitted to the Third Hospital of Hebei Medical University in the past 10 years were more common in males than in females,and predominant in physical workers.Fall and indoor activity was the most common injury cause.Schatzker types Ⅱ and Ⅵ prevailed.The fractures showed an aging trend by comparing the former 5 years and the latter 5 years.

Objective:To analyze the epidemiological characteristics of all the patients with intertrochanteric fracture admitted to the Third Hospital of Heibei Medical University in the past 10 years.Methods:Data of patients with intertrochanteric fracture admitted to our hospital from January 1, 2010 to December 31, 2019 were retrospectively analyzed. According to the year of admission, all the patients were divided into two groups: the first five years (group A) and the last five years (group B). Gender, age, injury cause, Evans classification, complicated diseases, length of hospital stay and whether surgical treatment or not were compared.Results:A total of 6,125 patients with intertrochanteric fracture were included in the study, including 2,664 males and 3,461 females with a male to female ratio of 0.77∶1. The peak age was 70-79 for males and 80-89 for females. There were 2,314 cases in group A (male to female ratio was 0.91∶1) and 3,811 cases in group B (0.70∶1), showing significant differences between the 2 groups in the male to female ratio ( χ2=25.265, P< 0.05). The peak age ranged from 70 to 80 years (31.9%,739/2,314) in group A and from 80 to 90 years (34.5%, 1,313/3,811) in group B. There were significant differences between the 2 groups in the sex ratios of age groups from 70 to 79 years ( χ2=0.024, P< 0.05). In all the 6,152 patients with a definite injury cause, the fall and indoor activity accounted for the highest proportion (83.9%, 5,140/6,125), and the proportion of group A was 75.4% (1,745/2,314) while the proportion of group B was 89.1%(3,395/3,811) showing a significant differences between the 2 groups in injury cause ( χ2=14.363, P< 0.05). Based on X-ray films or computer tomography (CT) of 3,560 patients, the Evans type II and III were the most common types. Type II accounted for the highest proportion in group A (38.1%, 239/628) while type III did in group B (39.5%, 1,159/2,932) . There were significant differences between the 2 groups in the proportion of Evans classification ( χ2=183.569, P< 0.05). Of all the 6,125 fracture cases, 4,846 fracture patients (79.1%) were complicated with medical diseases. There was a statistically significant difference between the 2 group of the patients who were complicated with medical diseases ( χ2=8.916, P< 0.05). A total of 5,148 patients were treated by operation and 1,925 patients were in group A while the other 3,259 cases were in group B. In group A, the median hospitalization was 14 days and the quartile interval was 8 days. In group B, the median hospitalization and the quartile interval was 12 days and 8 days respectively. There were significant differences between the 2 groups in length of hospital stay for patients treated by surgery ( Z=-9.909, P<0.001). Conclusion:The intertrochanteric fractures admitted to the Third Hospital of Heibei Medical University in the past 10 years were more common in females than in males. Fall and indoor activity was the most common injury cause. Evans types II and III prevailed. The fractures showed an aging trend by comparing the former 5 years and latter 5 years. The number of intertrochanteric fracture patients complicated with medical diseases increased significantly, but the total days of hospitalization was on the decline.

Objective:To explore the role of arthroscopic exploration in the treatment of tibial plateau fractures with homeopathic double reverse traction reduction and internal fixation.Methods:A retrospective analysis was conducted on the data of 188 patients with tibial plateau fractures treated by homeopathic double reverse traction reduction assisted internal fixation and arthroscopic exploration at the Third Hospital of Hebei Medical University from January 2019 to December 2021. There were 129 males and 59 females, aged 46.7±11.8 years (range, 14-80 years); 115 cases on the left and 73 cases on the right. Schatzker classification of fractures: 81 cases of type II, 15 cases of type III, 23 cases of type IV, 29 cases of type V, and 40 cases of type VI. The time from injury to surgery was 1-14 days, with an average of 10±5 days. The surgery was performed with double reverse traction assisted reduction, locking bone plate and self-breaking compression bolt fixation. Then, arthroscopy was used to explore the quality of fracture reduction, meniscus and ligament damage, and the corresponding intra-articular lesions were treated, such as partial meniscus resection, complete meniscus resection, or suturing. The Rasmussen score was used to evaluate the quality of fracture reduction after surgery, and the Hospital for Special Surgery (HSS) knee joint score was used to evaluate the postoperative function of the knee joint.Results:All patients successfully completed fracture reduction, fixation, and arthroscopic exploration. The average surgical time was 95±21 min (range, 30-120 min); The average intraoperative bleeding volume was 120±58 ml (range, 50-300 ml). All patients were followed up for 10-24 months, with an average of 18±6.5 months. All patients' fractures achieved clinical healing after surgery, with a healing time of 2.5-6.0 months, with an average of 3±2.4 months. Among them, 165 patients (87.8%, 165/188) healed within 3 months after surgery, while the remaining 23 patients healed within 4-6 months after surgery. Arthroscopic exploration revealed that 188 patients had good fracture reduction and a flat articular surface. Among them, 97 cases (51.6%, 97/188) were complicated with meniscus injury, with longitudinal tear (29%, 28/97) being the most common, suture treatment was performed under arthroscopy; the remaining 69 patients underwent partial meniscectomy. All the patient's knee function recovered well at the last follow-up. 29 cases (15.4%, 29/188) were complicated with cruciate ligament injury, none of them underwent primary repair and were fixed with plaster or brace after operation. The Rasmussen score for the final follow-up after surgery was 16.8±2.4 points (range, 6-18 points), with 152 cases being excellent and 36 cases being good, with a 100% excellent and good rate. The HSS knee joint scores were 79.8±9.2 points, 85.1±10.1 points, and 94.9±7.6 points at 3, 6 months after surgery, and at the last follow-up, respectively, with statistically significant differences ( F=52.53, P<0.001). Superficial skin infection occurred in 2 cases after operation, which was cured by regular dressing change and anti-infection treatment with antibiotics. Deep vein thrombosis occurred in 7 cases within 1 week after operation, and low molecular weight heparin anticoagulation therapy was given. Conclusion:After using double reverse traction assisted reduction and internal fixation, arthroscopic examination can not only evaluate the quality of reduction for tibial plateau fractures, but also handle combined meniscus injuries and evaluate the condition of cruciate ligament injuries.
