Clinical Analysis of Surgical Treatment of Senile Intertrochanteric Fracture Based on Intelligent Knowledge of Health Care

. In order to explore the clinical application value of intelligent health care knowledge combined with closed reduction intra-medullary nail ﬁxation in elderly patients with intertrochanteric fracture of the femur, a retrospective analysis is performed on 80 elderly patients who received intertrochanteric surgery from January 2019 to January 2021. All patients were divided into study group and control group based on intelligent medical knowledge received or not. During the phase of treatment, both the two groups were treated with closed reduction and intramedullary nailing. The control group received conventional knowledge training and rehabilitation before and after the surgery, and the research group received additional intelligent medical knowledge health care. Observations of patients after bed and ground time are compared and the VAS score is used to evaluate the pain degree at 12h, 24h, and 48h after surgery. Besides, the incidence of postoperative complications in the two groups is observed. From the clinical follow-up results, it is clearly evident that intramedullary nail ﬁxation based on medical care knowledge can eﬀectively improve the hip function and quality of life in patients, reduce postoperative pain, and improve the prognosis of elderly patients with femoral trochanteric fracture.


Introduction
Intertrochanteric fracture of femur refers to the fracture from the base of femoral neck to the level above the lesser trochanter.It is also a common injury in the elderly patients.Due to the abundant blood circulation in the trochanter, there is little non-union after the fracture.Intertrochanteric fracture of femur usually occurs in the elderly patients.is is because most elderly people have osteoporosis, which is likely to cause fractures in this part.e typical manifestation is hip pain and unable to stand and walk normally.
e specific type of intertrochanteric fracture can be judged by local X-ray, CT, and three-dimensional reconstruction.According to the statistical results, intertrochanteric fractures account for 7.01% of adult systemic fractures; and the elderly over 65 years old account for 23.79% of systemic fractures [1].At present, intertrochanteric fracture of the femur is treated with surgical fixation, and conservative treatment has a high incidence of complications.As China gradually enters an aging society, only 30% of patients can recover to a life before the injury.Many people die of complications without effective treatment.
e disease brings high mortality, nonunion, and teratogenesis rates, and high treatment costs.Some experts estimate that by 2020, the medical cost of hip fractures in China will reach 60 billion US dollars.
e increase in medical burden and poor prognosis leads to the decline of patients' quality of life, which brings a heavy economic burden to patients' families, and society [2,3].For the elderly patients with femoral intertrochanteric fracture, the clinical treatment includes conservative treatment and surgical treatment.Conservative treatment is mainly long-term bed traction, which usually leads to systemic complications.Within 2 weeks after the trauma, due to the decline of immune function, the incidence rate of pneumonia and infectious diseases is high.In addition, there are many surgical treatments, such as dynamic hip internal fixation, closed reduction and intramedullary nail fixation, and artificial hip replacement.However, there are still some disputes on the choice of the surgical scheme [4,5].In addition, some studies have also pointed out that due to the lack of medical care knowledge of elderly patients, they choose to stay in bed for a long time, so as not to affect their postoperative recovery, which is easy to cause muscle atrophy and joint stiffness.erefore, popularizing medical care knowledge is also of great significance to such patients [6].e aging of the population will directly lead to the rapid growth of the medical and health care needs of the elderly and form greater pressure on social medical resources [7].In addition to continuing research on medical technology, people have found that the rational use of the empowerment from digital technology is likely to be the "golden key" to solve the problem [8].Smart medicine has significant advantages in home medical services, remote consultation, and remote medical education services.
erefore, in this study, 80 elderly patients admitted to our hospital for intertrochanteric fracture from January 2019 to January 2021 were treated with closed reduction intramedullary nailing combined with intelligent healthcare knowledge to observe its impact on the prognosis of these patients.
is paper is organized as follows.In Section 2, the related work is reviewed.In Section 3, we present the general information and proposed method.In Section 4, the experimental results and analysis is discussed.Finally in Section 5, some concluding remarks are made.

Related Work
Intertrochanteric fracture of femur is a common injury in the elderly.Since most of the elderly are accompanied by chronic diseases such as hypertension and hyperglycemia, many nonsurgical complications are prone to occur in clinical treatment and lead to poor prognosis.Conservative treatment will further lead to bone nonunion and malunion in elderly patients.Long-term bed rest will also lead to muscle atrophy, joint stiffness, and pressure sores.
ese problems seriously threaten the physical and mental health of the elderly patients.erefore, appropriate medical care knowledge and effective surgical treatment are of great significance to the prognosis of elderly patients with a femoral intertrochanteric fracture [9].In current clinical according to a rotor between femur fractures have a variety of surgical plans, including the intramedullary nail fixation, and artificial hip replacement, can to a certain extent, improve the effect of fracture healing, recovery of hip joint function, and improve patients but treatment above is pure treatment, has yet to see the combined surgery and wisdom medical care and comparing observation curative effect [10].Based on this, this study used medical care knowledge to carry out rehabilitation training for elderly patients with an intertrochanteric fracture on the basis of intramedullary nail fixation and analyzed its application value for elderly patients with intertrochanteric fracture.
In preoperative elderly patients in advance in order to explain the procedure and to reduce the patients' fear of surgery, the postoperative activity can therefore be carried out in the field of rehabilitation training.
is study shows that the bed activity time and bed activity time of the team are shorter than those of the control group.And it can also illustrate the above views; preoperative intelligent health care knowledge can reduce the psychological burden of patients.It can help patients get out of bed early and move around and shorten the bed time [11].In addition, there were no significant difference in postoperative complications between the two groups, but the infection rate of the study group was slightly lower than that of the control group; hence, in this analysis, the authors' speculation may be due to two groups of patients who use surgery the same way, so the postoperative complications contrast will not have a too big difference, but the team in preoperative intelligent health care knowledge training, compared with the control group, have a more detailed understanding of what behaviors may cause infection by pulling the wound after surgery, so they pay more attention to these aspects, resulting in a lower wound infection rate [12].At the same time, in postoperative patients with lower limb venous thrombosis.causes are due to the fact that elderly are more worried about postoperative activities, no effective exercise lower limbs resulted in part of patients with lower extremity venous thrombosis, but the team received preoperative intelligent health care knowledge training.
ey have higher compliance and consciousness to postoperative rehabilitation treatment, as well as higher awareness of self-management, so the incidence of venous thrombosis of lower limbs is slightly lower [13].As this study is to evaluate by the Harris Hip Function, the results show two groups of patients with postoperative hip joint function improved, though six months after hip function had no significant difference in both the groups, but the study group 1 month after the surgery of the hip joint function was significantly better than control group, analyzes reasons for this recognition on the above as soon as possible after the activity and the benefits of exercise are fully understood.erefore, in the short term after surgery, patients can actively cooperate with rehabilitation exercise, so that patients can improve the function of hip joint earlier [14][15][16][17].In addition two kinds of treatment not only can improve the elderly patients with femoral fractures between rotor hip function, also can effectively improve the quality of life, and the team 1 months and 6 months after surgery improved quality of life of significantly higher, illustrate the team earlier recovery of hip function in patients with better blend in social activities, the ability to live independently, erefore, the quality of life is higher [18,19].Exclusion criteria are as follows [21]: (1) accompanied by mental diseases, unable to communicate with researchers normally; (2) lost contact or quit during the follow-up period; (3) the body cannot tolerate the operation; (4) poor treatment compliance cannot be coordinated with the study.

Surgical Methods.
Both the groups were treated with closed reduction and intramedullary nail xation during the operation.e speci c operation steps are as follows: (1) during the operation, the patients were in lateral or supine position and were anesthetized with general anesthesia and nerve block with an auxiliary line; (2) after the anesthesia took e ect, fracture reduction and traction were performed rst; (3) make a 5 cm incision upward at the top of the greater tubercle of femur, open the piriform fossa along the muscle bers of the median longitudinal incision, and slowly move the needle with the greater trochanter area as the midpoint; (4) the medullary cavity was expanded with a bone marrow expander until there was a suitable surgical space; (5) then continue to push the intramedullary nail and x it with the nail tail cap; (6) the wound was rinsed with normal saline, a drainage tube was left and sutured layer by layer.
Finally, both the groups were treated with broad-spectrum antibiotics for 24 hours to prevent infection.

Popularization of Intelligent Healthcare Knowledge.
In the control group, the relevant knowledge of postoperative rehabilitation and health care was popularized to the patients before the surgery, and the patients were instructed to carry out corresponding rehabilitation training after the surgery to promote the recovery of body functions.e speci c contents included: (1) ankle dorsi exion and quadriceps muscle training, through the maximum exion and extension of the ankle joint and resistance training according to the patient's personal situation, hip exion and knee bend 30 °-40 °training; (2) three days after the surgery, the a ected limb coasting rehabilitation was started, and the hip exion and knee bend Angle were increased to 40 °-60 °; (3) ve days after the surgery, walking training should be conducted with the assistance of medical sta or family members according to the patient's recovery.If pain or physical intolerance occurs during this training, the training should be stopped immediately; (4) voluntary hip movement can be performed about 4 weeks after the surgery, but the hip exion and knee bend Angle should not exceed 90 °, and weight training should not be avoided.
Compared with the control group, the research group received additional intelligent medical knowledge health care.e speci c contents include: (1) preoperative video interpretation about the operation process of the related content, popularize knowledge related to the operation, reduce the psychological burden of patients for surgery, so as to help patients keep relaxed, good response to treatment, and improve the follow-up rehabilitation compliance; (2) arrange professional rehabilitation personnel to simulate correct postures for patients before surgery, and explain how to protect themselves with correct postures in case of emergencies such as falls; (3) explain the possible causes of   1 illustrates the technical route.

Harris Hip Function Score.
e scale was mainly used to evaluate the e ect of hip replacement, including pain degree, daily functional performance, and range of motion, among which pain degree was scored 44 points, daily functional performance was scored 51 points, and range of motion was scored 5 points.e score range of this scale is 0 to 100, and the lower the score is, the worse the hip joint function is, unable to independently complete daily living operations.

World Health Organization Quality of Life (WHOQOL).
is scale has altogether four areas, respectively from the life health, feeling of things, action ability and the negative emotions seizure frequency was carried out on the quality of life assessment, and the top three areas respectively according to very poor, poor, in general, good, very good for 1 ∼ 5 points, respectively, according to the fourth eld never, rarely, sometimes, often, always remember to 5 ∼ 1 points.e scale ranges from 0 to 100, with a higher score indicating a better quality of life.

Visual Analogue Scale (VAS).
is scale is mainly used to evaluate the pain degree of patients.e speci c operation is to draw a line with a length of 10 cm on the paper, with one end marked as 0, indicating no pain.e other end is marked with a 10, indicating extreme pain, and patients are asked to mark on a straight line according to their own perception of pain.Scores ≤3 indicate mild pain and tolerable; A score of 4-6 indicates that the pain has a ected sleep but is still tolerable.A score of ≥7 indicates pain that is unbearable and interferes with daily life.

Observation Indicators.
e observation indicators include: (1) observe the postoperative time in bed and on the ground; (2) VAS score was used to compare the pain degree at 12h, 24h, and 48h after surgery; (3) the incidence of postoperative complications in the two groups was observed; (4) Harris Hip Function score was used to evaluate the hip function of the two groups before surgery, 1 month and 6 months after surgery; (5) the changes of quality of life in the two groups before and after treatment were compared.

Statistical
Processing.SPSS 25.0 statistical software was used for data analysis.(1) Measurement data: a normality test was performed on the data rst.If the data followed normal distribution and homogeneity of variance, it was represented by mean ± standard deviation.Paired sample t was used for testing within the group, and variance comparison was used between groups.Repeated measurement anOVA was used between multiple groups to conduct spherical test.(2) Count data: descriptive statistical analysis    2. e symbol " * " indicates that compared with 6h after surgery, * P < 0.05; "#" indicates that compared with 12h after surgery, #P < 0.05.In Figure 1, "a, b, c" indicates that if the same letter is shared, P > 0.05; if no common letter is shared, P < 0.05.Besides, the symbol "#" means the comparison of two components at the same time point P < 0.05. Figure 2 is the di erences in pain at di erent time points between the two groups.Figure 3 shows the volcanic map of di erence between two groups at time points.

Incidence of Postoperative Complications.
ere was no signi cant di erence in the incidence of total complications between the two groups, but the incidence of postoperative venous thrombosis and hip varus in the control group was slightly higher than that in the study group, as shown in Table 3.

Hip Function Evaluation.
After treatment, the hip function increased in both groups, and there was a significant di erence in hip function between the two groups 1 month after surgery (P < 0.05), and no di erence was observed in other time periods, as shown in Table 4 and Figures 4 and 5. e symbol " * " indicates that compared with preoperative, * P < 0.05; "#" indicates that compared with 1 month after surgery, # P < 0.05.In Figure 4, "a, b, c" means that if the same letter is used, there is no signi cant di erence between time points; "#" means that there is a signi cant di erence between the two groups at the same time point.

Quality of Life Evaluation.
Compared with before treatment, the quality of life in both groups improved after treatment, and the quality of life in the study group was signi cantly higher than the control group at 1 and 6 months after surgery (P < 0.05), as shown in Table 5 and Figure 6.
e symbol " * " indicates that compared with preoperative, * P < 0.05; "#" indicates that compared with 1 month after surgery, # P < 0.05.In Figure 6, "a, b, c" means that if the same letter is used, there is no signi cant difference between time points; "#" means that there is a signi cant di erence between the two groups at the same time point.Contrast Media & Molecular Imaging
