Deep vein thrombosis in bilateral lower extremities after hip fracture: a retrospective study of 463 patients

Objective To investigate the incidences of deep vein thrombosis (DVT) before and after operation in inpatients with hip fractures in both lower extremities. Patients and methods We collected the clinical data of 463 patients with lower extremities fractures who presented at Xi’an Honghui Hospital between July 1, 2014, and October 31, 2016 and met all the inclusion criteria. Doppler ultrasonography was used to diagnose DVT. The patients were examined preoperatively and postoperatively and divided into the thrombosis and non-thrombosis group according to the ultrasonographic findings. We divided the DVT cases into central, peripheral, and mixed thromboses. Results The incidence of preoperative DVT was 34.98%, and the prevalence of DVT on the uninjured side was 13.60%. This composition ratio increased to 57.23% postoperatively, and the prevalence of DVT on the uninjured side was 25.05%. Age (odds ratio [OR], 1.03; 95% CI: 1.01–1.04; P=0.002), venous thrombosis at admission (OR, 4.05; 95% CI, 2.30–7.13; P=0.000), and the days between the fracture and the operation (OR, 1.10; 95% CI, 1.02–1.20; P=0.020) were the independent risk factors of preoperative DVT. Coronary heart disease (OR, 1.85; 95% CI: 1.18–2.89; P=0.007), venous thrombosis at admission (OR, 22.35; 95% CI: 6.78–73.60; P=0.000), days between fracture and operation (OR, 1.06; 95% CI: 1.01–1.11; P=0.021), and blood loss (OR, 1.002; 95% CI: 1.000–1.003; P=0.014) were independent risk factors of postoperative DVT. Conclusion The actual incidence of DVT after hip fracture may be underestimated. The incidences of preoperative and postoperative DVTs and the incidence of DVT on the uninjured limb were high.

Interventions for treating displaced intracapsular femoral neck fractures in the elderly: a Bayesian network meta-analysis of randomized controlled trials

Displaced intracapsular femoral neck (AO type 31 B2/3) fractures have various treatments, including internal fixation (IF), unipolar uncemented hemiarthroplasty (HA), bipolar uncemented HA, unipolar cemented HA, bipolar cemented HA, uncemented total hip replacement (THR), and cemented THR. Systematic literature retrieval was performed from the databases to compare them in a network meta-analysis. Forty studies (85 arms) containing 6141 patients were included. Overall, our network meta-analysis rank the orders of 7 procedures in reoperation, mortality, dislocation and infection, which indicates that IF may provide the highest reoperation incidence, unipolar cemented HA may provide the lowest reoperation incidence; uncemented THR contributes the highest dislocation incidence; and bipolar uncemented HA provides the lowest infection incidence. No differences in mortality were observed among the treatments. This conclusion is indirect; higher-quality direct comparisons are required.

The role of ultrasonography in examination of the stability of Tile-B2 pelvic fractures: 7 case reports and a literature review

Background: Determining whether a Tile-B2 pelvic fracture is stable is very challenging. We sought to identify the role of ultrasonography in determining the stability of Tile-B2 pelvic fractures. Methods: We collected the clinical data of patients with Tile-B2 pelvic fractures who presented at Xi’an Hong-Hui Hospital between June 1, 2016, and August 5, 2016. The treatment strategy of each patient was determined by a team of senior surgeons in the department. A single sinologist observed the movement of the fracture sites in patients during rest, under compression, and during separation to determine fracture stability. According to the pelvic fracture stability assessment, an appropriate treatment strategy was redetermined. Overall, 7 patients, including 5 women and 2 men, with Tile-B2 pelvic fractures were included in this case series. Results: During the initial examination, senior surgeons recommended that 2 patients should undergo internal fixation and 4 patients, conservative treatment; treatment was undecided for 1 patient. After ultrasonography examination, 4 patients underwent surgery via the Stoppa (n = 2) or ilioinguinal approach (n = 1) or cannulated screw fixation (n = 1). The rest of the patients (n = 3) received conventional treatment. Follow-up ranged from 6 to 10 months. Most of the patients showed excellent functions based on their last Majeed grading scores. There were no complications during the follow-up. Using ultrasonography examination, the preoperative treatment plan in 1 patient was changed, and the uncertain preoperative plan in 1 patient was identified. Conclusion: Preoperative assessment of stability using ultrasonography may assist surgeons in making appropriate treatment choices for patients with Tile-B2 pelvic fractures.
