Abstract Objective To investigate the incidence of deep venous thrombosis (DVT) of the lower extremities following surgeries of tibial plateau fractures. Methods Retrospective analysis of the prospectively collected data on patients undergoing surgeries of tibial plateau fractures between October 2014 and December 2018 was conducted. Duplex ultrasonography (DUS) was used to screen for postoperative DVT of the bilateral lower extremities. Data on demographics, comorbidities, injury, surgery, and laboratory biomarkers at admission were collected. Univariate analyses and multivariate logistic regression analyses were used to identify the independent risk factors associated with DVT. Results Among 987 patients included, 46 (4.7%) had postoperative DVT, with incidence rate of 1.0% for proximal and 3.7% for distal DVT. The average interval between operation and DVT was 8.3 days (median, 5.8 days), ranging from 2 to 42 days. DVT involved the injured extremity in 39 (84.8%) patients, both the injured and uninjured extremity in 2 patients (4.3%) and only the uninjured extremity in 5 patients (10.9%). Five risk factors were identified to be associated with postoperative DVT, including age (≥ 41 vs < 41 years) (OR 3.08; 95% CI 1.43–6.61; p = 0.004), anesthesia (general vs regional) (OR 2.08; 95% CI 1.12–3.85; p = 0.021), hyponatremia (OR 2.21; 95% CI 1.21–4.06; p = 0.010), prolonged surgical time (OR 1.04; 95% CI 1.01–1.07; p = 0.017) and elevated D-dimer level (OR 2.79; 95% CI 1.34–4.83; p = 0.004). Conclusion These epidemiologic data may be helpful in individualized assessment, risk stratification, and development of targeted prevention programs.

Abstract Background There is still lack of data on deep vein thrombosis (DVT) following bone trauma. This study aimed to determine the epidemiologic characteristics of deep venous thrombosis (DVT) of lower extremities following tibial plateau fractures. Methods Retrospective analysis of prospectively collected data on patients presenting with tibial plateau fractures between October 2014 and December 2018 was conducted. Duplex ultrasonography (DUS) was routinely used to screen for preoperative DVT of bilateral lower extremities. Data on demographics, comorbidities, injury-related data, and laboratory biomarkers at admission were collected. Univariate analyses and multivariate logistic regression analyses were used to identify the independent risk factors associated with DVT. Results A total of 1179 patients were included, among whom 192 (16.3%) had a preoperative DVT, with incidence rate of 1.0% for proximal and 15.3% for distal DVT. The average interval between fracture occurrence and diagnosis of DVT was 3.5 days (median, 2 days), ranging from 0 to 19 days. DVT involved the injured extremity in 166 (86.4%) patients, both the injured and uninjured extremities in 14 patients (7.3%) and only the uninjured extremity in 12 patients (6.3%). Six risk factors were identified to be associated with DVT, including gender (male vs female), hypertension, open fracture, alkaline phosphatase > 100 u/L, sodium concentration < 135 mmol/L, and D-dimer > 0.5 mg/L. Conclusion These epidemiologic data are conducive to the individualized assessment, risk stratification, and development of targeted prevention programs.

Abstract Objective To investigate the incidence of postoperative deep venous thrombosis (DVP) in patients undergoing surgeries for ankle fractures and identify the associated risk factors.Methods This was a retrospective study. A total of 1451 patients undergoing surgery of ankle fractures from January 2016 to June 2019 were included. Their inpatient medical records were inquired for data collection, including demographics, comorbidities, injury and surgery-related data and laboratory biomarkers. DVT of lower extremity was diagnosed by routine doppler examination. Univariate analyses and multivariate logistic regression analyses were used to identify the independent risk factors.Results Among the 1451 patients, DVT was confirmed in 38 cases, indicating an incidence of 2.6%. DVT involved both the operated and non-operated limbs in 8 patients (21.1%). DVT involved superficial femoral vein in 4 cases (6.6%), deep femoral vein in 2 (3.3%), popliteal vein in 5 (8.2%), posterior tibial vein in 11 (18.0%) and peroneal vein in 39 (63.9%). The median interval between operation and diagnosis of DVT was7 days. Six risk factors were identified to be independently associated with DVT, including age (10-year increase) (OR, 1.44), preoperative stay (delay of each day) (OR, 1.11), anesthesia (general vs regional) (OR, 3.51), lower hemoglobin level (OR, 2.02), total cholesterol >5.2mmol/L (OR, 3.20) and reduced lymphocyte count (OR, 3.16).Conclusion These identified factors, although not easily modifiable, do help counsel patients about the risk of DVT and help individualized assessment of the risk factors and accordingly the risk stratification.

Abstract Background Limited information exists on the incidence of postoperative deep venous thromboembolism (DVT) in patients with isolated patella fractures. The objective of this study was to investigate the postoperative incidence and locations of deep venous thrombosis (DVT) of the lower extremity in patients who underwent isolated patella fractures and identify the associated risk factors. Methods Medical data of 716 hospitalized patients was collected. The patients had acute isolated patella fractures and were admitted at the 3rd Hospital of Hebei Medical University between January 1, 2016, and February 31, 2019. All patients met the inclusion criteria. Medical data was collected using the inpatient record system, which included the patient demographics, patient’s bad hobbies, comorbidities, past medical history, fracture and surgery-related factors, hematological biomarkers, total hospital stay, and preoperative stay. Doppler examination was conducted for the diagnosis of DVT. Univariate analyses and multivariate logistic regression analyses were used to identify the independent risk factors. Results Among the 716 patients, DVT was confirmed in 29 cases, indicating an incidence of 4.1%. DVT involved bilateral limbs (injured and uninjured) in one patient (3.4%). DVT involved superficial femoral common vein in 1 case (3.4%), popliteal vein in 6 cases (20.7%), posterior tibial vein in 11 cases (37.9%), and peroneal vein in 11 cases (37.9%). The median of the interval between surgery and diagnosis of DVT was 4.0 days (range, 1.0-8.0 days). Six variables were identified to be independent risk factors for DVT which included age category (> 65 years old), OR, 4.44 (1.34-14.71); arrhythmia, OR, 4.41 (1.20-16.15); intra-operative blood loss, OR, 1.01 (1.00-1.02); preoperative stay (delay of each day), OR, 1.43 (1.15-1.78); surgical duration, OR, 1.04 (1.03-1.06); LDL-C (> 3.37 mmol/L), OR, 2.98 (1.14-7.76). Conclusion Incidence of postoperative DVT in patients with isolated patella fractures is substantial. More attentions should be paid on postoperative DVT prophylaxis in patients with isolated patella fractures. Identification of associated risk factors can help clinicians recognize the risk population, assess the risk of DVT, and develop personalized prophylaxis strategies.

Abstract Objective The purpose of this study was to investigate the incidence, location, and related factors of deep venous thrombosis (DVT) of the bilateral lower extremities after intertrochanteric fractures in the elderly. Methods Retrospective analysis was performed on the elderly patients with intertrochanteric fracture who were admitted from January 2017 to December 2019. At admission, patients receive routine ultrasound Doppler scanning of bilateral lower extremities to detect DVT; those with DVT were assigned to the case group and those without DVT to the control group. Patient data on demographics, comorbidities, injury-related data, and laboratory test results at admission were extracted. Logistic regression analyses were conducted to identify the independent risk factors associated with DVT. Results Five hundred seventy-eight patients were included, among whom 116 (20.1%) had DVT. Among those with DV, 70.7% (82/116) had DVT of the distal type, 24 (29.6%) had DVT of the proximal type, and 10 (10.4%) had mixed DVT. In 76.7% (89/116) of patients, DVT occurred in the fractured extremity, 9.5% (11/116) in the bilateral and 13.8% (16/116) in the non-fractured extremity. Multivariate analyses identified obesity, delay to admission, increased D-dimer level (> 1.44 mg/L) and reduced albumin (< 31.7 g/L) as independent factors. Conclusions Admission incidence of DVT was high in elderly patients with intertrochanteric fractures, especially the proximal DVT. Identification of associated risk factors is useful for individualized assessment risk of DVT and early targeted interventions.

Objective This study aimed to assess using Doppler ultrasound for analyzing stability of deep venous thrombosis (DVT) of the lower extremities. Methods Patients with DVT of the lower extremities who were treated from August 2017 to December 2019 were selected. The patients were divided into stable and unstable groups according to whether thrombus was collected in a filter. Related ultrasound and blood test results were analyzed and compared. Results A total of 126 patients with DVT of the lower extremities were included, of whom 74 were in the stable group and 52 were in the unstable group. There were significant differences in the prothrombin time (PT), and lipoprotein alpha, D-dimer, and triglyceride levels between the groups. D-dimer levels >2800 ug/L, smoking, history of venous thrombosis, PT >13.15 s, and body mass index >24.45 kg/m2 were independent risk factors for stability of DVT of the lower extremities. The area under the curve with combined detection of DVT was significantly higher than that for body mass index, PT, and D-dimer alone. Conclusion Doppler ultrasound may be reliable for analyzing the stability of DVT of the lower extremities. Related strategies targeting risk factors are required for reducing DVT of the lower extremities.

Objective: The purpose behind this study was to determine the incidence and risk factors associated with post tibial plateau fracture deep venous thrombosis (DVT) Materials and Methods: A prospective study was conducted in a tertiary care hospital, Indus Medical College & Hospital, Tando Muhammad Khan to recruit those patients who were undergoing orthopedic surgeries during the periods of eighteen months. All the adult patients of both gender planned for surgery due to tibial plateau fracture were enrolled under this study. Duplex ultrasound was performed to detect the presence of underlying postoperative DVT. Post-operatively patients were assessed for potential risk factors associated with higher incidence of DVT.  Results: For the final analysis, 344 patients were included among them majority were males (n = 219, 63.66%) with overall mean age and SD was 47.52±12.02 years. The most common cause of fracture was road traffic accident (n = 178, 51.74%). The overall incidence of post-operative DVT observed in our study was 9.30% (n = 32). Mean age 40.19±6.10 years, increased mean duration of operation 3.01±.078 hours, increased mean duration of post-hospitalization 18.49±7.37 days, raised mean WBC counts 20.12±5.64, and increased mean D-dimer levels 3.24±3.09 (laboratory cut off value 0.5mg/L) were significantly associated with higher incidence of DVT in patients operated for tibial plateau fractures. Conclusion: This prospective analysis has identified the potential modifiable risk factors associated with DVT. Consideration should be given to the preventable and treatable risk factors to prevent from the DVT associated complications.

Foot Fractures

Background: This study was designed to investigate the incidence and hematological biomarker levels that are associated with deep venous thrombosis (DVT) following closed foot fractures (except calcaneal fractures). Methods: A retrospective analysis of data on patients presenting with closed foot fractures (excluding the calcaneus) between October 2014 and December 2018 was conducted. Duplex ultrasonography was used to screen preoperative DVT of bilateral lower extremities. Data on demographics, comorbidities, types of fracture, and laboratory biomarkers at admission were collected. Univariate analyses and multivariate logistic regression analyses were carried out to determine the independent risk factors associated with DVT. Results: A total of 537 patients were included, among whom 28 patients had preoperative DVTs, indicating a crude incidence rate of 5.2%. In isolated closed foot fractures, DVT occurred in 12 (2.9%) out of 410 patients, while in patients with concurrent fracture in other locations, 16 (12.6%) out of 127 patients developed DVT. The average interval between fracture occurrence and diagnosis of DVT was 4.2 days (median, 2 days), ranging from 0 to 17 days. Twenty-four patients (85.7%) developed DVT in the injured extremity, 3 (10.7%) in the uninjured extremity, and 1 (3.5%) in bilateral extremities. Seven risk factors were identified to be associated with DVT, including alcohol consumption, concomitant other fractures, platelet distribution width (PDW) <12%, high-density lipoprotein cholesterol (HDL-C) <1.1mmol/L, serum alkaline phosphatase (ALP) >100 U/L, serum sodium concentration (Na+) <135 mmol/L, and D-dimer >0.5 mg/L. Conclusion: Being aware of the prevalence of DVT in closed foot fractures can help physicians to carry out the overall assessment, risk stratification, and individual prevention programs. Level of Evidence: Level III, a prospective cohort study.

Abstract Background The preoperative prevalence of deep venous thromboembolism (DVT) of patella fracture is not well established. The study aimed to investigate the preoperative prevalence, the associated risk factors, and the locations of deep venous thrombosis (DVT) in patients with closed patella fracture. Methods Patients who sustained closed patella fracture between January 1, 2016, and April 1, 2019, were included. Blood analyses and ultrasonography of bilateral lower extremities were routinely performed. Data of demographics, comorbidities, mechanism of injury, fracture type, total hospital stay, time from injury to DVT, and laboratory indexes were prospectively collected and compared between groups with and with non-DVT. Multivariate logistic regression analyses were performed to determine the independent risk factors of DVT. Results Among the study cohort of 790 patients, 35 cases occurred in preoperative DVTs, indicating a prevalence of 4.4%, with 3.2% distal and 1.2% proximal DVT. Age ≥ 65 years old (OR, 3.0, 95% CI, 1.1–8.1), D-dimer > 0.5 mg/L (OR, 2.3, 95% CI, 1.1–4.8), and albumin < 35 g/L (OR, 2.5, 95% CI, 1.2–5.3) were identified to be risk factors of DVT in closed patella fracture. Among the DVTs, 30 cases (85.7%) occurred in the injured extremity, 3 cases (8.6%) in bilateral extremities, and 2 cases (5.7%) solely in the uninjured extremity. Conclusion The prevalence of preoperative DVT in closed patella fracture was 4.4%, with 3.2% for distal and 1.2% for proximal DVT. We recommend individualized risk stratification and early anticoagulation for patients with risk factors (age ≥ 65 years, D-dimer > 0.5 mg/L and albumin < 35g/L).

Objective To investigate the risk factors, predilection sites in pulmonary embolism (PE) patients caused by deep venous thrombosis (DVT) and explore the value of scoring systems in assessing the risk of PE in DVT patients. Methods A total of 692 DVT patients were enrolled, and divided into no pulmonary embolism (NPE, 226, 32.66%), silent pulmonary embolism (SPE, 330, 47.67%) and featuring pulmonary embolism (FPE, 136, 19.65%) groups. For each group, the differences of clinical data and PE locations were compared, and the risk factors of PE secondary to DVT were analyzed. The predictive value of the scoring system for the diagnosis of PE and FPE was evaluated. Results PE presented more in the bilateral pulmonary arteries (PAs) (249, 53.43%) and has no significant difference in PESI scores in different locations. Gender, DVT locations, and previous surgery were the independent risk factors of PE. DVT locations, previous history of COPD, and previous surgical interventions were the independent risk factors of FPE. The results for areas under the ROC curves were: AUC(Wells) = 0.675, AUC (Revised Geneva) = 0.601, AUC(D-dimer) = 0.595 in the PE group; AUC(Wells) = 0.722, AUC (Revised Geneva) = 0.643, AUC(D-dimer) = 0.557 in the FPE group. Conclusions PE secondary to DVT mostly occurs in the bilateral PAs. Male gender, DVT locations, and previous surgery increased the risk of PE. The Wells scoring system was more advantageous for evaluating the diagnosis of PE in patients with DVT.
