BACKGROUND: Senile intertrochanteric fracture is characterized as aging, instability, more complications and high mortality, so choosing an appropriate internal fixation method is critical.OBJECTIVE: To compare the curative efficacy of proximal femoral nail anti-rotation and locking proximal femoral plate for senile osteoporotic patients with unstable intertrochanteric fractures.METHODS: Sixty elderly patients with unstable intertrochanteric fractures were enrolled, and the clinical data were collected. They were randomized into treatment and control groups (n=30 per group), and subjected to internal fixation using proximal femoral nail anti-rotation and locking proximal femoral plate, respectively. The operative indexes,functional recovery and complications were observed in the two groups RESULTS AND CONCLUSION: (1) The incision length, operation time, intraoperative blood loss and time of weight bearing in the treatment group were significantly less than those in the control group (P < 0.01). (2) Harris hip scores in the treatment group were significantly higher than those in the control group (P < 0.05). (3) The incidence of complications in the treatment group was obviously lower than that in the control group. (4) To conclude, the proximal femoral nail anti-rotation exhibits satisfactory treatment outcomes in the internal fixation of unstable intertrochanteric fractures.

ObjectiveTo explore the correlations of university students'love style,dysfunctional attitude,and love satisfaction and life satisfaction.MethodsA total of 552 college students were assessed with relationship assessment scale(RAS),dysfunctional attitude scale(DAS),loving style scale(LSS) and life satisfaction index-A (LSIA).Results ( 1 ) The score of RAS of erotic loving style was ( 27.85 ± 4.624 ) significantly higher than the counterparts of the ludus loving style,which was (23.89 ± 4.061 ) (P ＜ 0.01 ).(2) There were significantly positive correlations among eros loving style,storge loving style,agape loving style,pragma loving style,life satisfaction and loving satisfaction,and negative correlations among Ludus loving style,dysfunctional attitude and loving satisfaction.(3)Loving satisfaction could be significantly predicted by dysfunctional attitude,eros loving style,ludus loving style,pragma loving style and storge loving style.ConclusionsLoving style and dysfunctional attitude can significantly predict loving satisfaction.

OBJECTIVE: To validate the effectiveness of a novel comprehensive classification for intertrochanteric fracture (ITF). METHODS: The study included 616 patients with ITF, including 279 males (45.29%) and 337 females (54.71%); the age ranged from 23 to 100 years, with an average of 72.5 years. Two orthopaedic residents (observers Ⅰ and Ⅱ) and two senior orthopaedic surgeons (observers Ⅲ and Ⅳ) were selected to classify the CT imaging data of 616 patients in a random order by using the AO/Orthopaedic Trauma Association (AO/OTA) classification of 1996/2007 edition, the AO/OTA classification of 2018 edition, and the novel comprehensive classification method at an interval of 1 month. Kappa consistency test was used to evaluate the intra-observer and inter-observer consistency of the three ITF classification systems. RESULTS: The inter-observer consistency of the three classification systems evaluated by 4 observers twice showed that the 3 classification systems had strong inter-observer consistency. Among them, the κ value of the novel comprehensive classification was higher than that of the AO/OTA classification of 1996/2007 edition and 2018 edition, and the experience of observers had a certain impact on the classification results, and the inter-observer consistency of orthopaedic residents was slightly better than that of senior orthopaedic surgeons. The intra-observer consistency of two evaluations of three classification systems by 4 observers showed that the consistency of the novel comprehensive classification was better for the other 3 observers, except that the consistency of observer Ⅳ in the AO/OTA classification of 2018 version was slightly higher than that of the novel comprehensive classification. The results showed that the novel comprehensive classification has higher repeatability, and the intra-observer consistency of senior orthopaedic surgeons was better than that of orthopaedic residents. CONCLUSION The novel comprehensive classification system has good intra- and inter-observer consistency, and has high validity in the classification of CT images of ITF patients; the experience of observers has a certain impact on the results of the three classification systems, and those with more experiences have higher intra-observer consistency.
