Project description:In 2007 the Dutch Surgical Society published a clinical practice guideline for the treatment of hip fracture patients, based on the best available international evidence at that time. We investigated to what extent treatment of femoral neck fracture patients in the Netherlands corresponded with these guidelines, and determined differences in patient characteristics between the treatment groups.All femoral neck fracture patients treated in 14 hospitals between February 2008 and August 2009 were included. Patient characteristics, X-rays, and treatment data were collected retrospectively.From a total of 1,250 patients 59% had been treated with arthroplasty, 39% with internal fixation, and 2% with a non-operative treatment. While 74% of the treatment choices complied with the guideline, 12% did not. In 14% adherence could not be determined from the available data. Arthroplasty was preferred over internal fixation in elderly patients with severe comorbidity, pre-fracture osteoporosis and a displaced fracture, who were ambulatory with aids pre-fracture (odds ratio, OR 2.2-58.1). Sliding hip screws were preferred over cancellous screws in displaced fractures (OR 1.9).Overall guideline adherence was good. Most deviations concerned treatment of elderly patients with a displaced fracture and implant use in internal fixation. Additional data on these issues, preferably at a higher scientific level of evidence, is needed in order to improve the guideline and to reinforce a more uniform treatment of these patients.

Project description:Background and purposeProsthetic joint infection (PJI) remains a devastating complication of arthroplasty. Today, most displaced femoral neck fractures in the elderly are treated with arthroplasty. We estimated the incidence of and risk factors for PJI in primary arthroplasty after femoral neck fracture.Patients and methodsPatients admitted for a femoral neck fracture in 2008 and 2009 were registered prospectively. We studied clinical, operative, and infection data in 184 consecutive patients.Results9% of the patients developed a PJI. Coagulase-negative staphylococci and Staphylococcus aureus were the most frequently isolated organisms. We found that preoperative waiting time was associated with PJI and also with urinary tract infection. The median preoperative waiting time was 37 (11-136) h in the infection group as opposed to 26 (4-133) h in the group with no infection (p = 0.04). The difference remained statistically significant after adjusted analysis. The success of treatment with debridement and retention of the prosthesis was limited, and 5 of the 17 patients with PJI ended up with a resection arthroplasty. The 1-year mortality rate was 21% in the patients with no infection, and it was 47% in the infection group (p = 0.03).InterpretationWe found a high incidence of PJI in this elderly population treated with arthroplasty after hip fracture, with possibly devastating outcome. The length of stay preoperatively increased the risk of developing PJI.

Project description:This study aimed to determine the kinetics of four inflammatory markers and to identify the variables that affect the natural kinetics of inflammatory markers in aged patients having hip fractures with and without elevated preoperative CRP. 240 elderly patients who have been operated on for femoral neck fracture with no infectious complications were divided into two groups on elevated preoperative CRP level (>10?mg/L). The temporal values of four inflammatory markers of WBC, neutrophil count (N) (%), ESR, and CRP were assessed eight times every other day until the 14th postoperative day. At 48-60?h postoperatively, mean CRP was markedly higher in patients with preoperatively elevated CRP than in those with nonelevated CRP (122.1 ± 65.9 and 73.7 ± 35.5, p < 0.001). However, the abrupt elevation of CRP in the elevated group was conversely decreased on the 4th-5th postoperative day, demonstrating similar kinetic curves with no significant differences between both groups. For WBC, N (%), and ESR, both groups showed similar patterns of temporal values 14 days after surgery regardless of preoperative CRP level. Our findings could be used as guidelines for patient discharge and during the follow-up period after surgery.

Project description:PurposePrevious studies have proved that vascular endothelial growth factor (VEGF) has a dual role in the promotion of new bone formation and blood vessel repair during fracture healing. However, how to introduce VEGF to a fracture site safely and effectively is still a challenge. This study aimed to prepare a VEGF-loaded nanographene coated internal fixation screw and to evaluate its effects in the treatment of femoral neck fracture.MethodsNanographene coated screws were prepared by direct liquid-phase exfoliation of the graphite method, and the surface characteristics were observed through scanning electron microscopy (SEM). VEGF was loaded on nanographene coatings through physical adsorption, and the VEGF controlled release was examined by ELISA. Then a canine femoral neck fracture model was built to examine both the angiogenic and osteogenic properties of the VEGF-loaded coated screws. X-ray, micro-CT-based microangiography, and histopathologic evaluation were used to assess the fracture healing progress.ResultsThe results demonstrated that nanographene could load VEGF effectively, and the accumulative release of VEGF clearly increased during the entire testing period (9 days) without burst release. In canine fracture models, the results of X-ray, microangiography, and histopathologic examination proved that the speed of fracture healing, new bone formation area, and revascularization of the fractured femoral heads in the VEGF-loaded coated screws groups were significantly higher than in the control groups.ConclusionOur study proved that VEGF-loaded nanographene coated screws were effective in the treatment of femoral neck fracture and prevention of avascular necrosis of femoral head.

Project description:Femoral neck fracture (FNF) is a common condition with a rising incidence, partly due to aging of the population. It is recommended that FNF should be treated at the earliest opportunity, during daytime hours, including weekends. However, early surgery shortens the available time for preoperative medical examination. Cardiac evaluation is critical for good surgical outcomes as most of these patients are older and frail with other comorbid conditions, such as heart failure. The aim of this study was to determine the impact of heart failure on in-hospital outcomes after surgical femoral neck fracture treatment. We performed a retrospective study using the Spanish National Hospital Discharge Database, 2007-2015. We included patients older than 64 years treated for reduction and internal fixation of FNF. Demographic characteristics of patients, as well as administrative variables, related to patient's diseases and procedures performed during the episode were evaluated. A total of 234,159 episodes with FNF reduction and internal fixation were identified from Spanish National Health System hospitals during the study period; 986 (0.42%) episodes were excluded, resulting in a final study population of 233,173 episodes. Mean age was 83.7 (±7) years and 179,949 (77.2%) were women (p < 0.001). In the sample, 13,417 (5.8%) episodes had a main or secondary diagnosis of heart failure (HF) (p < 0.001). HF patients had a mean age of 86.1 (±6.3) years, significantly older than the rest (p < 0.001). All the major complications studied showed a higher incidence in patients with HF (p < 0.001). Unadjusted in-hospital mortality was 4.1%, which was significantly higher in patients with HF (18.2%) compared to those without HF (3.3%) (p < 0.001). The average length of stay (LOS) was 11.9 (±9.1) and was also significantly higher in the group with HF (16.5 ± 13.1 vs. 11.6 ± 8.7; p < 0.001). Patients with HF undergoing FNF surgery have longer length of stay and higher rates of both major complications and mortality than those without HF. Although their average length of stay has decreased in the last few years, their mortality rate has remained unchanged.

Project description:ObjectiveThis meta-analysis aimed to compare the relative safety and efficacy of cannulated compression screw (CCS) and femoral neck system (FNS) in treating patients with femoral neck fractures and to provide evidence-based medical evidence for FNS in treating femoral neck fractures.MethodsPubMed, Embase, Cochrane, and China National Knowledge Infrastructure databases were searched to collect outcomes related to femoral neck fractures treated with FNS and CCS, including time to fracture healing, incidence of non-union, incidence of osteonecrosis of the femoral head, incidence of failure of internal fixation, rate of femoral neck shortening, Harris hip score, Barthel index, operative time, intraoperative blood loss, fluoroscopy frequency, and complications. A meta-analysis was performed using RevManv5.4 (The Cochrane Collaboration) and Stata v14.0 software.ResultsThis analysis included 21 studies involving 1,347 patients. The results showed that FNS was superior to CCS in terms of fracture healing time [mean difference (MD) = -0.75, 95% CI = (-1.04, -0.46), P < 0.05], incidence of bone non-union [odds ratio (OR) = 0.53, 95% CI = (0.29, 0.98), P = 0.04], incidence of osteonecrosis of the femoral head [OR = 0.49, 95% CI = (0.28, 0.86), P = 0.01], incidence of internal fixation failure [OR = 0.30, 95% CI = (0.18, 0.52), P < 0.05], rate of femoral neck shortening [OR = 0.38, 95% CI = (0.27, 0.54), P > 0.05], Harris hip score [MD = 3.31, 95% CI = (1.99, 4.63), P < 0.001], Barthel index [MD = 4.31, 95% CI = (3.02, 5.61), P < 0.05], intraoperative bleeding [MD = 14.72, 95% CI = (8.52, 20.92), P < 0.05], fluoroscopy frequency [OR = 0.53, 95% CI = (0.29, 0.98), P = 0.04], and complications [OR = 0.31, 95% CI = (0.22, 0.45), P < 0.05]. The difference between FNS and CCS in operative time was not statistically significant [MD = -2.41, 95% CI = (-6.88, 2.05), P = 0.29].ConclusionFNS treatment of femoral neck fracture can shorten the fracture healing time; reduce the incidence and translucent rate of bone non-union, osteonecrosis of the femoral head, and internal fixation failure; reduce intraoperative blood loss and postoperative complications; and improve hip joint function and activity. We are confident in the findings that FNS, an effective and safe procedure for internal fixation of femoral neck fractures, is superior to CCS.

Project description:Purpose/introductionTooth loss has been found to be associated with fractures and osteoporosis. However, the associations between number of teeth with bone mineral density as well as with hip fractures have not been explored in the same study setting.MethodsData from the cross-sectional National Health and Nutrition Examination Survey (2005-2010, 2013-2014, and 2017-2018) with completed femoral neck bone mineral density (BMD) measurements, osteoporosis questionnaires, and dentition examinations were analyzed. A total of 15,198 participants, with a mean age of 53.9 and diverse ethnicity, males (52%), and females (48%), were analyzed. Multivariate logistic regression analyses for self-reported hip fractures, self-reported osteoporosis, and measured low femoral BMD accounting for traditional risk factors were tested for the total number of natural teeth (NoT) present, or by NoT in the anterior or posterior segments.ResultsSubjects with fewer natural teeth present were more likely to report a hip fracture, osteoporosis, or having lower levels of femoral neck BMD. With one additional tooth present in the mouth, there was a decreased association with self-reported hip fracture [OR(95%CI) = 0.98(0.96-0.99); P = 0.005] or with less likelihood of having low femoral neck BMD [OR(95%CI) = 0.99(0.97-1.00); P = 0.007].ConclusionsWith the limitation of the cross-sectional study design, results should be interpreted cautiously, yet our analyses point to an association between a decreased number of natural teeth present and self-reported hip fractures or low femoral neck BMD. The number of teeth present could be potentially utilized for assessing risks of hip fracture and osteoporosis. Future research is needed to validate our findings.

Project description:BackgroundClosed reduction and percutaneous cannulated screw fixation is the preferred surgical method for treating femoral neck fractures in elderly patients under 70 years old. The key to the operation is the precise insertion of the guide pin after the successful reduction. However, there is no universally accepted standard for the localization of the guide pin insertion point. This study introduces our invention of a localization method for guide pin insertion points.MethodsWe used fluoroscopic frequency, operative time, union rates, and complications to retrospectively evaluate the treatment and outcome of femoral neck fractures using our localization method for guide pin insertion points. The study included ten patients treated at Affiliated Hospital of Shandong University of Traditional Chinese Medicine between 2010 and 2014 for femoral neck fracture using our localization method for guide pin insertion points.ResultsOur results showed that the mean number of fluoroscopies was 5 (range, 4-8), and the mean operative time was 32 minutes (range, 25-51 minutes). All 10 patients achieved union at an average of 3.4 months (range, 2.8-6.2 months) without complications after the operation. The average follow-up time was 13.2 months (range, 12.2-16 months). The treatment of femoral neck fracture with our localization method for guide pin insertion points resulted in satisfactory curative efficacy without complications.ConclusionsOur localization method offers distinct advantages, including the accuracy and simplicity of the operation, a low rate of complications, and adequate biomechanical stability. As such, it provides a feasible method for clinical treatment.

Project description:The aim of present study is to evaluate the outcome of bone marrow instillation at the fracture site in fracture of intracapsular neck femur treated by head preserving surgery.This study included 32 patients of age group 18-50 years with closed fracture of intracapsular neck femur. Patients were randomized into two groups as per the plan generated via www.randomization.com. The two groups were Group A (control), in which the fracture of intracapsular neck femur was treated by closed reduction and cannulated cancellous screw fixation, and Group B (intervention), in which additional percutaneous autologous bone marrow aspirate instillation at fracture site was done along with cannulated cancellous screw fixation. Postoperatively the union at fracture site and avascular necrosis of the femoral head were assessed on serial plain radiographs at final follow-up. Functional outcome was evaluated by Harris hip score.The average follow-up was 19.6 months. Twelve patients in each group had union and 4 patients had signs of nonunion. One patient from each group had avascular necrosis of the femoral head. The average Harris hip score at final follow-up in Group A was 80.50 and in Group B was 75.73, which was found to be not significant.There is no significant role of adding on bone marrow aspirate instillation at the fracture site in cases of fresh fracture of intracapsular neck femur treated by head preserving surgery in terms of accelerating the bone healing and reducing the incidence of femoral head necrosis.

Project description:The fracture hematoma that forms between the broken fragments of bone serves as a natural fibrin scaffold. However, there is no data regarding the differences between the micro-architectural and biological properties of hematomas formed in normally healing, delayed healing, and non-healing bone defects. Mimicking these three conditions in the rat femur, we demonstrate clear differences in fibrin clot morphology, which directly affect the gene expression pattern. Specifically, RNA-sequencing reveals that the expression of essential osteogenic genes in normally healing defects are significantly up-regulated, whereas in delayed and non-healing defects they are down-regulated. Surprisingly, there were no substantial differences between delayed and non-healing defects. Most importantly, this study demonstrates that the healing outcome has already been determined at the earliest stage of bone healing. These findings could be used to develop biomaterial scaffolds mimicking the micro-architectural properties of normally healing fracture hematoma as a treatment strategy for bone defects. The hypothesis of this study was that the micro-architectural properties of the initially formed hematoma has a significant effect on the regulation of the biological process at the fracture site, which ultimately determines the outcome of bone healing. Three different healing models were investigated - normally healing, delayed healing, and non-healing defects. The results demonstrated that the intrinsic micro-architectural properties of hematomas between those groups varied distinctly in terms of fiber diameter, porosity, and density of the formed fibrin network. Those differences influenced biological responses, as evidenced by a higher expression of osteogenic genes in normally healing compared to delayed and non-healing defects, and the failed activation of BMP-2 in non-healing defects. More importantly, our results demonstrate healing outcomes are already determined at the initial (hematoma) stage of bone healing.
