“…Pauwels type III femoral neck fracture has a large fracture angle, compared with the other two fracture types, the fracture line angle is the largest, which increases the shearing force in the fracture site and easily results in reduction loss, shortening of the femoral neck, and fracture nonunion [25,26]. Research shows that appropriate internal xation can provide a good mechanical environment for femoral neck fracture and improve the cure rate of femoral neck fracture [27].…”

BackgroundThe optimum internal fixation approach for femoral neck fracture therapy is still debated, and there are few studies on calcar femorale repair following femoral neck fracture. The biomechanical properties of various internal fixation systems can be adequately studied using the finite element method. The goal of this work was to use finite element analysis to examine the biomechanical parameters of Pauwels type III femoral neck fractures under various calcar femorale repair nailing procedures.MethodThe finite element approach was used to numerically investigate the calcar femorale reconstruction method for femoral neck fracture repair. A control group with standard inverted triangle nail placement and internal fixation models with calcar femorale reconstruction nails of 150, 155, and 160 degrees, respectively, were constructed. The four groups of models' von Mises stress and displacement distributions are evaluated and compared.ResultsIn the control group and three calcar femorale reconstruction nail angle models, the maximum stress of femur was (MPa): 106.605, 87.317, 147.691, and 102.072 respectively; The peak stress of four kinds of internal fixation were (MPa): 315.121, 228.819, 198.173 and 208.798. In the control group and three calcar femorale reconstruction nail angle models, the maximum displacement of the femur was (mm): 13.19, 13.183, 12.443, and 12.896 respectively; The displacement peaks of the four internal fixations were (mm): 12.646, 12.625, 11.932 and 12.347.ConclusionsAccording to the results of finite element analysis, the biomechanical performance of calcar femorale reconstruction nail with 150 ° is excellent, which is helpful to the reconstruction of calcar femorale structure. This nail placement method can achieve better biomechanical properties. The results of this study can provide a theoretical reference for clinical practice.

“…Osteonecrosis of the femoral head (ONFH) is a major cause of reoperation for FNF (8). Joint disfunction, pain, disability, and mental anguish caused by ONFH result in great suffering for patients (9)(10)(11). End-stage ONFH often inevitably requires artificial joint replacement surgery, an invasive and economically costly technique.…”

Deep Learning Improves Osteonecrosis Prediction of Femoral Head After Internal Fixation Using Hybrid Patient and Radiograph Variables

et al. 2020

Femoral neck fractures (FNFs) are a great public health problem that leads to a high incidence of death and dysfunction. Osteonecrosis of the femoral head (ONFH) after internal fixation of FNF is a frequently reported complication and a major cause for reoperation. Early intervention can prevent osteonecrosis aggravation at the preliminary stage. However, at present, failure to diagnose asymptomatic ONFH after FNF fixation hinders effective intervention at early stages. The primary objective of this study was to develop a predictive model for postoperative ONFH using deep learning (DL) methods developed using plain X-ray radiographs and hybrid patient variables. A two-center retrospective study of patients who underwent closed reduction and cannulated screw fixation was performed. We trained a convolutional neural network (CNN) model using postoperative pelvic radiographs and the output regressive radiograph variables. A less experienced orthopedic doctor, and an experienced orthopedic doctor also evaluated and diagnosed the patients using postoperative pelvic radiographs. Hybrid nomograms were developed based on patient and radiograph variables to determine predictive performance. A total of 238 patients, including 95 ONFH patients and 143 non-ONFH patients, were included. A CNN model was trained using postoperative radiographs and output radiograph variables. The accuracy of the validation set was 0.873 for the CNN model, and the algorithm achieved an area under the curve (AUC) value of 0.912 for the prediction. The diagnostic and predictive ability of the algorithm was superior to that of the two doctors, based on the postoperative X-rays. The addition of DL-based radiograph variables to the clinical nomogram improved predictive performance, resulting in an AUC of 0.948 (95% CI, 0.920-0.976) and better calibration. The decision curve analysis showed that adding the DL increased the clinical usefulness of the nomogram compared with a clinical approach alone. In conclusion, we constructed a DL facilitated nomogram that incorporated a hybrid of radiograph and patient variables, which can be used to improve the prediction of preoperative osteonecrosis of the femoral head after internal fixation.

Aseptic necrosis of the femoral head (ANFH) is a severe chronic poliaethiologic disease of the hip joint which is prevalent mainly in young people with a loss of professional and social skills. It is known that the non-psychotic mental disorders appearance in patients with ANFH can lead to the increasing disability, the decreasing in the quality of life, and difficulties in organizing the rehabilitation period. Current researches prove that the preoperative mental state assessment in patients can lead to the statistically significant decrease of the pain intensity in the postoperative period, an improvement in the quality of life related to health, a decrease in anxiety, depression and behavioural problems in the postoperative period. The aim of this research was to study the syndromic features of non-psychotic mental disorders, alexithymia and anxiety levels in patients with ANFH at the preoperative stage. The study involved 137 people aged 25 to 75 years, who were diagnosed with ANFH and identified non-psychotic mental disorders. Clinical-psychopathological and psychodiagnostic methods of examination were used (AUDIT test, Toronto alexithymia scale-20, Taylor manifest anxiety scale). The patients were divided into two groups depending on the ANFH duration. The results of the study revealed the main leading syndromes: asthenic-depressive – in 35.8%, depressive-hypochondriac – in 18.2%, anxious-phobic – in 16.1%, anxious-depressive - in 15.3% and astheno-apathetic – in 14.6% of cases. The average anxiety score was 26 (19; 37), which indicates the presence of a medium-high level of anxiety in the examined, while 52.5 percent of patients had high and very high levels of anxiety. A multivariate logistic regression analysis was performed and as a result, the duration of the disease (OR: 2.23; 95% [CI]: 1.11-4.47; p<0.05), estimates of alexithymia (OR: 2.52; 95% [CI]: 1.00-6.36; p<0.05) and female sex (OR: 2.16; 95% [CI]: 1.03-4.50; p<0.05) were found to be independent risk factors associated with the level of anxiety in persons with ANFH at the preoperative stage.
