## Abstract

Objective. To assess the efficacy of targeted perioperative management for diabetic patients with traumatic calcaneal fractures. Methods. Between April 2020 and December 2020, 100 diabetic patients with traumatic calcaneal fractures treated in our institution satisfying the inclusion criteria were enrolled and assigned to receive either conventional treatment with surgery or plaster fixation (observation group) or targeted treatment with surgery or plaster fixation (experimental group) via the random number table method, with 50 patients in each group. All eligible patients were followed up for 1 year postoperatively. Outcome measures included length of hospital stay, recovery time, fracture healing, duration of postoperative wound drainage, complication rate, blood glucose, and treatment satisfaction. The Maryland score was used for the assessment of foot function. Results. The duration of postoperative wound drainage, length of hospital stay, and recovery time in the experimental group (3.63 ± 1.04 d, 12.13 ± 3.77 d, and 111.22 ± 16.24 d) were significantly shorter than those in the observation group (5.71 ± 2.34 d, 15.28 ± 4.42 d, 123.10 ± 22.82 d) (P<0.01). The experimental group obtained a markedly higher complete healing rate versus the observation group (P<0.001). A significantly lower complication rate was observed in the experimental group than in the observation group (P<0.05). The Maryland scores results were dichotomized into good (≥75 points) and poor (<75 points). The experimental group showed significantly higher Maryland scores good rate and treatment satisfaction versus the observation group (P<0.01). The experimental group patients were associated with better postoperative fasting glucose and 2 h postprandial glucose versus those in the observation group (P<0.05). Conclusion. Targeted treatment in the perioperative management of diabetic patients with traumatic calcaneal fractures significantly promotes the recovery of patients, reduces the incidence of complications, increases treatment satisfaction, and ameliorates the doctor-patient relationship.

## Body

## 1. Introduction

The calcaneus is the largest tarsal bone in the human body and is an important component of the foot arch. The calcaneus has a complex anatomy and irregular morphology, with six surfaces and four articular facets. The calcaneus is the common posterior jaw of the posterior branch of the medial and lateral longitudinal arches of the foot, and its anterior end supports the talus and bears the weight of the body. The upper part of the calcaneus consists of three articular surfaces, which, together with the talus, comprise the subtalar joint complex and maintain the mechanical stability of the subtalar joint. The posterior articular surface of the calcaneus bears the majority of the body mass. Calcaneal fractures are a common clinical fracture type and are associated with up to 60% of tarsal fractures. Treatment of calcaneal fractures is complicated and prone to various complications, so how to ensure effective treatment outcomes and lower the incidence of complications remains one of the pressing issues to be addressed in orthopedics. Surgery is the mainstay of treatment for poor alignment of broken bones, and cast fixation is adopted for good alignment. Diabetes mellitus is a common metabolic disorder with a high prevalence worldwide. It is characterized by hyperglycemia elicited by defective insulin secretion, insulin action, or both. Statistics showed that the proportion of diabetic patients worldwide was approximately 25.6% in 2015. The disease is highly liable to complications, such as cardiovascular and cerebrovascular diseases, neurological diseases, and nephropathies, and may lead to malignant neoplastic diseases in the event of disease deterioration without timely treatment. Diabetes is a major risk factor for cardiovascular disease. The treatment of diabetes is complicated and no significant breakthroughs have been achieved. Thus, early screening and diagnosis are of great significance. The high blood glucose of diabetic patients with traumatic calcaneal fractures may retard fracture healing, and the patients are predisposed to postoperative complications such as incisional infections, which compromise the recovery of foot function and the quality of life of the patients [1–3]. It has been suggested that the combination of perioperative targeted therapeutic interventions contributes to reducing postoperative complications and shortening the recovery time [4, 5]. To this end, this study was conducted to assess the efficacy of targeted treatment in the perioperative management of diabetic patients with traumatic calcaneal fractures.


## 2. Materials and Method

### 2.1. Baseline Data

Between April 2020 and December 2020, 100 patients with traumatic calcaneal fractures combined with diabetes mellitus treated in our institution satisfying the inclusion criteria were enrolled and assigned to receive either conventional treatment with surgery or plaster fixation (observation group) or targeted treatment with surgery or plaster fixation (experimental group) via random number table methods, with 50 patients in each group. In the observation group, there were 24 females and 26 males, aged between 25 and 66 years, with an average age of 38.5 ± 4.2 years. In terms of the cause of injury, there were 21 cases of traffic accidents, 17 cases of falling from height, and 12 cases of sports injuries; in terms of Sanders fracture classification, there were 17 cases of type II, 21 cases of type III, and 12 cases of type IV. In the experimental group, there were 23 females and 27 males, aged between 24 and 66 years, with a mean age of (38.3 ± 4.4) years. In terms of the cause of injury, there were 22 cases of traffic accidents, 16 cases of falling from height, and 12 cases of sports injuries; in terms of Sanders fracture classification, there were 19 cases of type II, 20 cases of type III, and 11 cases of type IV. The studies involving human participants were reviewed and approved by the Ethics Committee of Jinan Zhangqiu District People’s Hospital (Approval no. 97770/93).Inclusion criteria were as follows: patients with calcaneal fractures confirmed by imaging and who met the indications for surgical treatment; patients who were diagnosed with diabetes mellitus with fasting blood glucose of ≥7.0 mmol/L and 2 h postprandial blood glucose (2hPBG) of ≥11.1 mmol/L; and patients who voluntarily participated in the study and provided written informed consent were included.Exclusion criteria were as follows: patients with minor fractures, not requiring inpatient surgery; patients with cardiovascular, cerebrovascular, endocrine, liver, and kidney insufficiency, and other chronic medical diseases; and patients with the withdrawal of consent were considered ineligible and excluded.There was no statistically significant difference between the two groups in terms of baseline features such as gender, age, cause of injury, fasting glucose, and fracture types (P>0.05) (Table 1). The study was approved by the medical ethics review board.Table 1

### 2.2. Methods

Patients in the observation group received conventional treatment, including precautions, health education, postoperative basic maintenance, and discharge instructions. Patients in the experimental group received targeted treatment, including preoperative, intraoperative, and postoperative management [6, 7].


#### 2.2.1. Preoperative Management

(1) The nursing staff actively communicated with the patients to understand their psychological state and helped them relieve negative emotions to improve their treatment cooperation [8, 9]. (2) The patients were given health education, including the causes of diabetes mellitus, blood glucose control, and care for calcaneal fractures. Patients were also given dietary instructions for strict control of sugar intake and were advised to have more coarse grains, vegetables, fruits, high protein, and high calcium foods to promote recovery [10].


#### 2.2.2. Intraoperative Management

(1) Patients who required surgery were treated with incisional repositioning and internal fixation. An enlarged L-shaped incision was used, and a suitable lateral heel plate and screws were used for fixation after satisfactory repositioning. The closure of the surgical incision was performed by the same operator and assistant, and the subcutaneous tissues were closed intermittently to avoid dead cavities, followed by the placement of a drainage tube. Disposable skin sutures (Changzhou Heraeus PWHW35) were applied to staple the incision. (2) Patients who did not need surgery were treated with plaster fixation.


#### 2.2.3. Postoperative Management

(1) After the procedure, the patient was maintained in a prone position and the affected limb was elevated to an appropriate angle to facilitate venous blood return. The blood circulation, skin color, and temperature of the patient’s foot were monitored, and antibiotics were administered to prevent infection [11, 12]. The patients received insulin injections and their blood glucose was determined thrice daily for the adjustment of their insulin dose. (2) The patients’ wounds were monitored, and the property and color of the drains were observed in case of abnormalities. The drainage tubes were removed 3 d after the surgery. The affected limbs were checked for swelling, and the patients were instructed to perform ankle exercises. If necessary, the affected limbs were massaged to promote blood circulation. Exercise instruction was given based on recovery. (3) Diabetic patients with high levels of D-dimer expression are prone to lower limb deep vein thrombosis, so drugs to dilate blood vessels and improve peripheral blood circulation were administered before and after surgery to prevent limb deep vein thrombosis. The patients were instructed to perform active exercises such as ankle exercises and quadriceps, and their family members were guided to massage the affected limb of the patients from the distal end to the proximal end. Lower extremity vascular ultrasound was performed to clarify the disease condition if the affected extremity was severely swollen, and early symptoms of pulmonary embolism were managed promptly.


#### 2.2.4. Blood Glucose Management

After understanding the patient’s living habits and diet structure, a tailored diet protocol was formulated to control the patient’s daily intake of sugar, fat, and protein for effective glucose and blood lipid management. Patients with traumatic fractures and diabetes mellitus suffer severe physical and mental shock, resulting in massive physical exertion, negative nitrogen balance, increased secretion of endocrine hormones, and elevated blood glucose. The patients were instructed to eat nutritious and low-sugar foods, with whole wheat flour in place of refined flour and mixed grain rice in place of white rice. Patients were advised to consume more vegetables and proteins such as milk, lean meat, poultry, eggs, fish, and soy products. Patients were advised against greasy foods such as peanuts and nuts. They were also instructed to have a daylong stream of mini-meals and increase consumption of calcium-containing foods.


### 2.3. Outcomes

The hospital-made questionnaire and pathology records were used to compare the length of hospital stay, recovery time, fracture healing, duration of postoperative wound drainage, complication rate, blood glucose changes, and treatment satisfaction between the two groups, and the Maryland score was used to assess the patients’ foot function.(1)
Criteria for Fracture Healing. Complete healing: there were no tenderness and no percussion pain along the longitudinal axis of the limb, and no discomfort from self-elevation of the affected limb, and the fracture line disappeared on X-ray. Basic healing: there were no tenderness and no percussion pain along the longitudinal axis of the limb, with possible discomfort from self-elevation of the affected limb, and the fracture line was blurred on X-ray.(2)
Complications. The complications during treatment include surgical wound infection, delayed healing, healing deformity, and joint pain.(3)
Determination of Blood Glucose. 4 mL of peripheral venous blood was collected from all eligible patients before and after treatment, and the serum was isolated by centrifugation at 3000 r/min for 15 min (centrifugal radius of 10 cm) using a C1012-E blood centrifuge (Wuxi Microchromatography Biotechnology Co. Ltd.) with original reagents to determine serum fasting blood glucose and postprandial 2 h blood glucose level.(4)
Treatment Satisfaction. A questionnaire prepared by our hospital was used, with a total of 16 questions. The total score is 48 points, with 3 points for satisfied, 2 points for basic satisfied, and 0 points for dissatisfied. The formula for score calculation is as follows: the sum of the scores obtained from the questionnaire/48 ∗ 100%. Satisfied: final score >40 points; basically satisfied: final score of 24–40 points; unsatisfied: final score ≤24 points.(5)
Maryland Scoring Criteria. 40 points: no obvious pain; 30 points: occasional mild pain; 20 points: occasional moderate pain; 0 points: frequent severe pain. 10 points: no restriction of activity; 8 points: slight restriction of activity, 0 points: severe restriction of activity. 10 points: normal healing; 8 points: slight deformity; 6 points: moderate deformity; 0 points: severe deformity. The score was 100 points, in which excellent was ≥90 points, good was 75–90 points, moderate was 50–74 points, and poor was ≤50 points.


### 2.4. Statistical Analysis

SPSS 20.0 was used for data analysis, and GraphPad Prism 8 was used to plot the graphics. The measurement data are expressed as mean ± standard deviation and analyzed using the independent samplest-test. The count data are expressed as cases (%) and analyzed using the chi-square test. Hierarchical data were compared using the rank-sum test. Differences were considered statistically significant at P<0.05.

## 4. Discussion

Fluctuation of blood glucose in diabetic patients may be attributed to intraoperative stress. Thus, patients' blood glucose during perioperative management requires timely control and observation of complications to enhance the therapeutic efficacy of surgery [13–15]. Targeted management is a high-quality management model developed in recent years and refers to the adoption of targeted perioperative management measures to promote early recovery and shorten the hospital stay of patients [16–18]. Fracture, surgery, and diabetes are prone to interact with each other and become a vicious circle. Perioperative targeted therapeutic interventions allow active control of blood glucose levels to closely observe the presence of diabetic complications. Psychological care improves patient compliance, and early functional exercise enhances patients’ self-care ability, thereby promoting disease recovery and improving their quality of life. The greatest risks for patients with calcaneal fractures are nonhealing wounds, nonunion of the fracture and infection, so it is crucial to fully understand the condition of the diabetic patient and the medication used before surgery [19]. Diabetic patients with poor blood circulation in the heel require additional attention to blood circulation in the distal limb. Physical means and medications, including radiofrequency, laser, far infrared, and pneumatic pumps, are timely administered to protect the soft tissues and prevent local blister formation and skin breakdown to ensure a smooth procedure. Due to the paucity of clinical studies on the application of perioperative targeted management in patients with traumatic calcaneal fractures complicated by diabetes mellitus, this study aimed to investigate the effectiveness of the targeted management model on the rehabilitation process of patients with traumatic calcaneal fractures complicated by diabetes mellitus. The results of this study showed that the experimental group obtained a significantly shorter length of hospital stay and recovery time, and higher complete healing rates and Maryland scores versus the observation group, which was consistent with the research results by Wang Hongtao, suggesting that the targeted perioperative management effectively improves the fracture healing rate, reduces patients’ pain, and improves patients’ foot function after surgery. The reason may be that targeted treatment is tailored to the patient’s specific situation and adjusted promptly according to their recovery. The psychological counseling of the patients before surgery significantly strengthens their treatment cooperation, and the close monitoring of the patient’s vital signs and recovery after surgery allows for timely detection and management of abnormalities.Diabetes mellitus is associated with a slow recovery. A previous study indicated that patients with intraoperative hyperglycemia had higher anastomotic leakage rates than patients with a normal blood glucose level (12% versus 5%,P<0.001) [19]. Therefore, a proper diet was necessitated to ensure enough nutrients for patients and enable better healing and faster recovery. The results of the present study showed that the experimental group showed better blood glucose results than the observation group, indicating the benefits of targeted perioperative management in the reduction and control of blood glucose. Moreover, the results of this study also revealed a higher safety profile of targeted perioperative management in comparison with conventional treatment, as evidenced by the lower incidence of complications in the experimental group versus the observation group, which may be attributable to the high quality of management that mitigated the surgical stress and enhanced the psychological status and prognosis of patients in the present study. The study by Zhang Lu et al. demonstrated that targeted management showed significant improvements in eliminating negative emotions, lowering the risk of complications, and relieving pain, which boosted postoperative recovery and ameliorated patients’ quality of life. Furthermore, patients receiving targeted management in the present study were more satisfied with the treatment, which indicates that the protocol is feasible [20–22].To sum up, the application of targeted treatment in the perioperative management of diabetic patients with traumatic calcaneal fractures significantly promotes the recovery of patients, reduces the incidence of complications, increases treatment satisfaction, and ameliorates the doctor-patient relationship.
