RESUMO
A significant amount of all paediatric fractures are forearm fractures involving the radius, ulnar shaft, or both. As surgical stabilisation lowers the likelihood of re-displacement, surgical intervention is currently recommended over conservative treatment of such fractures involving significant displacement and angulation. Open reduction and plating can better anatomically repair the majority of fractures. Bracing is necessary for the first six to eight weeks after nailing since nailing does not give a rigid fixation. External bracing is generally not necessary for plating. In our facility, paediatric diaphyseal forearm fractures are typically treated using titanium elastic nail system (TENS) nailing. However, there are occasional instances where the primary fracture site refractures after surgery, particularly in diaphyseal forearm fractures involving both bones. Our patient was a 12-year-old boy who had come to our facility with a left forearm radius shaft fracture and ulna shaft plastic deformation. The radius shaft fracture was fixed with TENS nailing, and the ulna shaft plastic deformation was corrected by the three-point bending method. Three months later, the patient came back with a refracture of the radius shaft. TENS nail removal, open reduction, and internal fixation of the radius shaft refracture were done with a plate and screws. Anatomic reduction of forearm fractures, open reduction, and the use of plate fixation enable a more thorough correction of malrotation and restoration of the radial bow, allowing for an early range of motion. Since the TENS nail is not a locking device, there is always some amount of mobility at the fracture site, causing loss of reduction, chances of implant failure, and non-union. So primary plating, especially in cases of forearm fractures, appears to be a better option compared to primary TENS nailing in juvenile patients.
RESUMO
Patients who sustain a hip fracture are known to be at imminent refracture risk. Their complex multidisciplinary rehabilitation needs to include falls prevention and anti-osteoporosis medication (AOM) to prevent such fractures. This study aimed to determine which hospital-level organizational factors predict prescription of post-hip fracture AOM and refracture risk. A cohort of 178 757 patients aged ≥60 yr who sustained a hip fracture in England and Wales (2016-2019) was examined and followed for 1 yr. Patient-level hospital admission datasets from 172 hospitals, the National Hip Fracture Database, and mortality data were linked to 71 metrics extracted from 18 hospital-level organizational reports. Multilevel models determined organizational factors, independent of patient case-mix, associated with (1) AOM prescription and (2) refracture (by ICD10 coding). Patients were mean (SD) 82.7 (8.6) yr old, 71% female, with 18% admitted from care homes. Overall, 101 735 (57%) were prescribed AOM during admission, while 50 354 (28%) died during 1-yr follow-up, 12 240 (7%) refractured. Twelve organizational factors were associated with AOM prescription, for example, orthogeriatrician-led care compared to traditional care models (odds ratio [OR] 4.65 [95% CI, 2.25-9.59]); AOM was 9% (95% CI, 6%-13%) more likely to be prescribed in hospitals providing routine bone health assessment to all patients. Refracture occurred at median 126 d (IQR 59-234). Eight organizational factors were associated with refracture risk; hospitals providing orthogeriatrician assessment to all patients within 72 h of admission had an 18% (95% CI, 2%-31%) lower refracture risk, weekend physiotherapy provision had an 8% (95% CI, 3%-14%) lower risk, and where occupational therapists attended clinical governance meetings, a 7% (95% CI, 2%-12%) lower risk. Delays initiating post-discharge community rehabilitation were associated with a 15% (95% CI, 3%-29%) greater refracture risk. These novel, national findings highlight the importance of orthogeriatrician, physiotherapist, and occupational therapist involvement in secondary fracture prevention post hip fracture; notably, fracture risk reductions were seen within 12 mo of hip fracture.
Patients who have broken (fractured) a hip are at risk of having another fracture soon after. They have complex needs to avoid more fractures, which include being prescribed bone-strengthening medicines and taking measures to prevent falls. This study looked at which of the measurements, that describe how well a hospital is organized, are associated with whether bone-strengthening medicine is prescribed and the chance of having another fracture. We used data from 178 757 patients aged over 60 yr who had a hip fracture at 172 English and Welsh hospitals, linked to their hospital records, and other datasets that describe hospital services. Overall, 57% of patients were prescribed bone-strengthening medicines, and 7% went on to have another fracture. Bone-strengthening medicines were more likely to be prescribed in hospitals where patient care was led by a consultant specializing in the care of older people with fractures (called orthogeriatricians) and in hospitals which routinely checked patients' bone health. Patients attending hospitals that provided orthogeriatrician assessment to all patients within 72 h of being admitted, physiotherapy services at the weekend, or where occupational therapists attended meetings aimed at improving hospital services had a lower chance of having another fracture.

INTRODUCTION: To investigate the clinical value of serum albumin to alkaline phosphatase ratio (AAPR) in predicting the risk of osteoporotic vertebral refractures group (OVRFs) after percutaneous vertebral augmentation (PVA) in postmenopausal women. MATERIALS AND METHODS: This is a retrospective case-control study including a series of postmenopausal women patients with osteoporotic vertebral fracture (OVF) and underwent PVA. Patients were divided into OVRFs and non-OVRFs. COX model was used to evaluate the correlation between preoperative AAPR and OVRFs after PVA. The receiver operating characteristic (ROC) curve and Kaplan-Meier method were used to analyze the predictive value of AAPR for the incidence of OVRFs. RESULTS: A total of 305 patients were included in the final study, and the incidence of postoperative OVRFs was 28.9%. Multivariate COX analysis showed that advanced age (HRs = 1.062, p = 0.002), low BMI (HRs = 0.923, p = 0.036), low AAPR (HRs = 0.019, p = 0.001), previous fall history (HRs = 3.503, p = 0.001), denosumab treatment (HRs = 0.409, p = 0.007), low L3 BMD (HRs = 0.977, p = 0.001) and low L3 paravertebral muscle density (PMD)value (HRs = 0.929, p = 0.001)) were closely related to the incidence of OVRFs. The area under the curve (AUC) of AAPR for predicting OVRFs was 0.740 (p < 0.001), and the optimal diagnostic cut-off value was 0.49. Kaplan-Meier curve analysis showed that low AAPR group (< 0.49) was significantly associated with lower OVRFs-free survival (p = 0.001; log-rank test). CONCLUSION: AAPR is an independent risk factor for OVRFs after PVA in postmenopausal women, and it can be used as an effective index to predict OVRFs.
RESUMO
OBJECTIVES: To establish a predictive model to evaluate the risk of adjacent vertebral refracture (VRF) after percutaneous kyphoplasty (PKP) for osteoporotic vertebral compression fracture (OVCF) based on perioperative imaging data. METHODS: This study was a retrospective cohort study which established a predictive model of VRF after PKP for OVCF. Patients who underwent PKP for OVCF in our hospital between January 2018 and December 2020 were enrolled and divided into a refracture group and normal group. Perioperative imaging data including preoperative bone mineral density (BMD), fatty infiltration (FI%) of paravertebral muscle, sagittal parameters of the spine and pelvis, and recovery rate of vertebral height were collected. The prediction model is obtained by multifactor logistic regression analysis. RESULTS: A total of 242 patients were included, including 23 cases in the VRF group and 219 cases in the normal group. There were statistical differences in BMD, FI%, recovery rate of vertebral height, and sagittal imbalance between the 2 groups. Receiver operating characteristic curve analysis of continuous variables showed that BMD ≤-2.80, FI% ≥40%, and recovery rate of vertebral height ≥ 10% were the cutoff values. Logistic regression analysis showed that BMD ≤-2.80, FI% ≥40%, and sagittal imbalance were independent risk factors for VRF. The area under the curve according to the predicted probability was 0.85 (P < 0.05). After simplifying the model, the total point of the model was 7 points, with a cutoff value of 5 points. CONCLUSIONS: The prediction model obtained in this study can predict refracture after PKP for OVCF early and effectively. It has an excellent predictive effect which is suitable for clinicians.
RESUMO
AIMS: This study aimed to compare the clinical effectiveness of intramedullary nailing (IMN), percutaneous external plate fixation (PEPF), and re-applied external fixation (REF) in the treatment of refracture at the consolidated docking site following the removal of external fixation in patients with tibial defects who had previously undergone the Ilizarov bone transport technique. METHODS: A retrospective review was performed on patients who received IMN, PEPF, or REF for refracture at the consolidated docking site subsequent to the removal of external fixation. A collection of data was made regarding the following parameters: age, gender, defect size, treatment methods, external fixation time (EFT), external fixation index (EFI), time of refracture (TOR) subsequent to fixation removal, and docking reunion time (DRT). Bone and functional outcomes were evaluated by the Association for the Study and Application of the Method of Ilizarov (ASAMI) scoring system and the Lower Extremity Functional Scale (LEFS) questionnaire. RESULTS: The study included 14 males and 5 females with an average age of 38.1 ± 8.9 years (range, 26 to 55 years). Etiologies included post-traumatic osteomyelitis in 11 cases and post-traumatic bone loss in 8 cases. The median bone defect was 5.11 ± 0.87 cm (range, 3.8 to 6.8 cm). Following docking site refracture, 6 cases were treated with IMN, 8 with PEPF, and 5 with REF. All patients achieved both satisfactory bone union and functional outcomes, and there was no significant difference in preoperative baseline data or postoperative outcomes among the three groups. CONCLUSION: IMN, PEPF, and REF were all demonstrated favorable postoperative bone and functional outcomes, suggesting their reliability as treatment options for managing docking site refracture following external fixation removal.

BACKGROUND: The reaserch of artificial intelligence (AI) model for predicting spinal refracture is limited to bone mineral density, X-ray and some conventional laboratory indicators, which has its own limitations. Besides, it lacks specific indicators related to osteoporosis and imaging factors that can better reflect bone quality, such as computed tomography (CT). OBJECTIVE: To construct a novel predicting model based on bone turn-over markers and CT to identify patients who were more inclined to suffer spine refracture. METHODS: CT images and clinical information of 383 patients (training set = 240 cases of osteoporotic vertebral compression fractures (OVCF), validation set = 63, test set = 80) were retrospectively collected from January 2015 to October 2022 at three medical centers. The U-net model was adopted to automatically segment ROI. Three-dimensional (3D) cropping of all spine regions was used to achieve the final ROI regions including 3D_Full and 3D_RoiOnly. We used the Densenet 121-3D model to model the cropped region and simultaneously build a T-NIPT prediction model. Diagnostics of deep learning models were assessed by constructing ROC curves. We generated calibration curves to assess the calibration performance. Additionally, decision curve analysis (DCA) was used to assess the clinical utility of the predictive models. RESULTS: The performance of the test model is comparable to its performance on the training set (dice coefficients of 0.798, an mIOU of 0.755, an SA of 0.767, and an OS of 0.017). Univariable and multivariable analysis indicate that T_P1NT was an independent risk factor for refracture. The performance of predicting refractures in different ROI regions showed that 3D_Full model exhibits the highest calibration performance, with a Hosmer-Lemeshow goodness-of-fit (HL) test statistic exceeding 0.05. The analysis of the training and test sets showed that the 3D_Full model, which integrates clinical and deep learning results, demonstrated superior performance with significant improvement (p-value < 0.05) compared to using clinical features independently or using only 3D_RoiOnly. CONCLUSION: T_P1NT was an independent risk factor of refracture. Our 3D-FULL model showed better performance in predicting high-risk population of spine refracture than other models and junior doctors do. This model can be applicable to real-world translation due to its automatic segmentation and detection.

Objective: This study aimed to explore the impact of sarcopenia on clinical outcomes after percutaneous kyphoplasty (PKP) for osteoporotic vertebral compression fracture (OVCF). Methods: We retrospectively analyzed the medical records of patients with single-segment OVCF who underwent percutaneous kyphoplasty (PKP) between September 2021 and August 2022. Patients were categorized into a sarcopenia group (43 patients) and a non-sarcopenia group (125 patients) based on their Advanced Skeletal Muscle Index (ASMI). Clinical and radiological data were collected and analyzed. Results: There were no significant differences between the sarcopenia and non-sarcopenia groups in age, sex, bone mineral density (BMD), body mass index (BMI), fractured segment, fracture type, surgical approach, bone cement volume, bone cement distribution, comorbidities, preoperative and immediate postoperative VAS and ODI scores (P > .05). However, the time to ambulation, hospital stays, VAS and ODI scores at follow-up, excellent/good rate, and the incidence of residual pain and re-fractures in the non-sarcopenia group were significantly better than those in the sarcopenia group (P < .05). Meanwhile, radiological outcomes, including regional kyphosis and vertebral height loss rate, were significantly better in the non-sarcopenia group than in the sarcopenia group at 6 and 12 month follow-ups (P < .05). Conclusion: Clinical outcomes after PKP in patients with OVCF could be negatively affected by sarcopenia. Therefore, prevention and treatment of sarcopenia should be actively considered in the management of patients with OVCF.
RESUMO
We conducted a retrospective cohort analysis to examine the association between hemoglobin (Hb) levels and refracture risk in elderly patients with osteoporotic fractures (OPFs). Our findings suggest a nonlinear relationship exists in females, and females with Hb levels below 10.7 g/dL may be at a higher risk of refracture. INTRODUCTION: Hematopoiesis and bone health have a reciprocal influence on each other. Nevertheless, there is a scarcity of in-depth research on the association between Hb levels and the occurrence of fractures. The present research aimed to investigate the correlation between Hb levels and the rate of refracture within 5 years among individuals with OPFs. METHODS: A retrospective cohort analysis was undertaken between 2017 and 2022. The study included 1906 individuals who were inhabitants of Kunshan and were over 60 years old. These individuals had experienced an OPF between January 1, 2017, and July 27, 2022, resulting in their hospitalization. Cox proportional hazard regression models were used to evaluate the risk of refracture within 5 years based on the Hb levels acquired during the admission examination, with consideration for sex differences. A nonlinear relationship was identified using smoothed curve fitting and threshold analysis. Kaplan-Meier curves were used to compare refracture rates between patients with low and high Hb levels. RESULTS: Elderly female patients with OPFs and lower Hb levels exhibited a significantly higher risk of a 5-year refracture. Conversely, no significant associations were observed between the two variables in male patients. A nonlinear correlation was found between Hb levels and the probability of refracture in females, with a turning point identified at 10.7 g/dL of Hb levels. A strong negative association was observed with the five-year refracture rate when Hb levels fell below 10.7 g/dL (hazard ratio (HR) = 0.63; 95% confidence interval (CI) 0.48 to 0.83; P-value = 0.0008). This finding suggests that for every 1 g/dL increase in Hb below 10.7 g/dL, the risk of refracture reduced by 37%. However, no statistically significant association was observed when Hb levels were above 10.7 g/dL. CONCLUSIONS: The findings demonstrated a significant negative correlation between Hb levels and the likelihood of refracture in elderly female patients with OPFs and suggested that elderly females with recent OPFs and Hb levels below 10.7 g/dL may be at a higher risk of refracture. Additionally, the Hb levels can serve as an indicator of bone fragility in elderly female patients with OPFs. These findings highlight the importance of monitoring Hb levels as a part of comprehensive management strategies to both assess skeletal health and prevent refractures in this population.
RESUMO
BACKGROUND: Osteoporotic vertebral compression fractures (OVCF) in the elderly increase refracture risk post-surgery, leading to higher mortality rates. Genome-wide association studies (GWAS) have identified susceptibility genes for osteoporosis, but the phenotypic variance explained by these genes has been limited, indicating the need to explore additional causal factors. Epigenetic modifications, such as DNA methylation, may influence osteoporosis and refracture risk. However, prospective cohorts for assessing epigenetic alterations in Chinese elderly patients are lacking. Here, we propose to conduct a prospective cohort study to investigate the causal network of DNA polymorphisms, DNA methylation, and environmental factors on the development of osteoporosis and the risk of refracture. METHODS: We will collect vertebral and peripheral blood from 500 elderly OVCF patients undergoing surgery, extract DNA, and generate whole genome genotype data and DNA methylation data. Observation indicators will be collected and combined with one-year follow-up data. A healthy control group will be selected from a natural population cohort. Epigenome-wide association studies (EWAS) of osteoporosis and bone mineral density will be conducted. Differential methylation analysis will compare candidate gene methylation patterns in patients with and without refracture. Multi-omics prediction models using genetic variants and DNA methylation sites will be built to predict OVCF risk. DISCUSSION: This study will be the first large-scale population-based study of osteoporosis and bone mineral density phenotypes based on genome-wide data, multi-time point methylation data, and phenotype data. By analyzing methylation changes related to osteoporosis and bone mineral density in OVCF patients, the study will explore the feasibility of DNA methylation in evaluating postoperative osteoporosis intervention effects. The findings may identify new molecular markers for effective anti-osteoporosis treatment and inform individualized prevention and treatment strategies.

The refracture rate after major trauma is approximately half (57%) the refracture rate after a minimal trauma injury. Extending Fracture Liaison Service activity to include major trauma patients creates significant additional direct cost, but remains essentially cost neutral if notional savings through refracture risk reduction are taken into account. PURPOSE: To compare the 3-year refracture rate following minimal trauma (MT) and non-minimal trauma (non-MT) injuries and evaluate the cost of extending fracture liaison service (FLS) operations to non-MT presentations. METHODS: Patients aged 50, or above presenting to the John Hunter Hospital with a fracture in calendar year 2018 were identified through the Integrated Patient Management System (IPMS) of the Hunter New England Health Service's (HNEHS), and re-presentation to any HNEHS facility over the following 3 years monitored. The refracture rate of MT and non-MT presentations was compared and analysed using Cox proportional hazards regression models. The cost of including non-MT patients was estimated through the use of a previously conducted micro-costing analysis. The operational fidelity of the FLS to the previous estimate was confirmed by comparing the 3-year refracture rate of MT presentations in the two studies. RESULTS: The 3-year refracture rate following a MT injury was 8% and after non-MT injury 4.5%. Extension of FLS activities to include non-MT patients in 2022 would have cost an additional $198,326 AUD with a notional loss/saving of $ - 26,625/ + 26,913 AUD through refracture risk reduction. No clinically available characteristic at presentation predictive of increased refracture risk was identified. CONCLUSION: The 3-year refracture after a non-MT injury is about half (57%) that of the refracture rate after a MT injury. Extending FLS activity to non-MT patients incurs a significant additional direct cost but remains cost neutral if notional savings gained through reduction in refracture risk are taken into account.

PURPOSE: To analyze the association between scoliosis and vertebral refracture after percutaneous kyphoplasty (PKP) in patients with osteoporotic vertebral compression fractures (OVCFs). METHODS: A retrospective study was conducted on 269 patients meeting the criteria from January 2014 to October 2022. All patients underwent PKP with complete data and were followed-up for > 12 months. First, it was verified that scoliosis was a risk factor in 269 patients. Second, patients with scoliosis were grouped based on the Cobb angle to evaluate the impact of the post-operative angle. The cox proportional hazards regression analysis and survival analysis were used to calculate the hazard ratio and recurrence time. RESULTS: A total of 56 patients had scoliosis, 18 of whom experienced refractures after PKP. The risk factors for vertebral refractures included a T-score < - 3.0 and presence of scoliosis (both p < 0.001). The results indicated that the vertebral fractured arc (T10 - L4) was highly influential in scoliosis and vertebral fractures. When scoliotic and initially fractured vertebrae were situated within T10 - L4, the risk factors for vertebral refracture included a postoperative Cobb angle of ≥ 20° (p = 0.002) and an increased angle (p = 0.001). The mean recurrence times were 17.2 (10.7 - 23.7) months and 17.6 (7.9 - 27.3) months, respectively. CONCLUSION: Osteoporosis combined with scoliosis significantly increases the risk of vertebral refractures after PKP in patients with OVCFs. A postoperative Cobb angle of ≥ 20° and an increased angle are significant risk factors for vertebral refractures when scoliotic and initially fractured vertebrae are situated within T10 - L4.

OBJECTIVE: To understand immediate and long-term outcomes following hip fracture surgery in adults with schizophrenia. METHODS: Retrospective population-based cohort study leveraging health administrative databases from Ontario, Canada. Individuals aged 40-105 years with hip fracture surgery between April 1, 2009 and March 31, 2019 were included. Schizophrenia was ascertained using a validated algorithm. Outcomes were: 30-day mortality; 30-day readmission; 1-year survival; and subsequent hip fracture within 2 years. Analyses incorporated Generalized Estimating Equation models, Kaplan-Meier curves, and Fine-Gray competing risk models. RESULTS: In this cohort study of 98,126 surgically managed hip fracture patients, the median [IQR] age was 83[75-89] years, 69.2% were women, and 3700(3.8%) had schizophrenia. In Fine-Gray models, schizophrenia was associated with subsequent hip fracture (sdRH, 1.29; 95% CI, 1.09-1.53), with male patients with schizophrenia sustaining a refracture 50 days earlier. In age- and sex-adjusted GEE models, schizophrenia was associated with 30-day mortality (OR, 1.31; 95% CI, 1.12-1.54) and readmissions (OR, 1.40; 95% CI, 1.25-1.56). Kaplan-Meier survival curves suggested that patients with schizophrenia were less likely to be alive at 1-year. CONCLUSIONS: Study highlights the susceptibility of hip fracture patients with schizophrenia to worse outcomes, including refracture, with implications for understanding modifiable processes of care to optimize their recovery.

BACKGROUND: Hip fractures are the most serious fragility fractures due to their associated disability, higher hospitalization costs and high mortality rates. Fracture Liaison Service (FLS) programs have enhanced the management of osteoporosis-related fractures and have shown their clinical effectiveness. AIMS: To analyze the effect of the implementation of a FLS model of care over the survival and mortality rates following a hip fracture. METHODS: We conducted a prospective cohort study on patients over 60 years of age who suffered a hip fracture before and after the implementation of the FLS in our center (between January 2016 and December 2019). Patients were followed for three years after the index date. Mortality, complications and refracture rates were compared between the two groups using a Multivariate Cox proportional hazard model. RESULTS: A total of 1366 patients were included in this study (353 before FLS implementation and 1013 after FLS implementation). Anti-osteoporotic drugs were more frequently prescribed after FLS implementation (79.3% vs 12.5%; p < 0.01) and there was an increase in adherence to treatment (51.7% vs 30.2%; p < 0.01). A total of 413 (40.8%) patients after FLS implementation and 141 (39.9%) individuals before (p = 0.47) died during the three-years follow-up period. A second fracture occurred in 101 (10.0%) patients after FLS implementation and 37 (10.5%) individuals before (p = 0.78). Patients after the implementation of the FLS protocol had a lower all cause one-year mortality [adjusted Hazard Ratio (HR) 0.74 (0.57-0.94)] and a decreased risk of suffering a second osteoporotic fracture [adjusted HR 0.54 (0.39-0.75) in males and adjusted HR 0.46 (0.30-0.71) in females]. CONCLUSIONS: The implementation of a FLS protocol was associated with a lower all-cause one-year mortality rate and a higher survivorship in elderly hip fracture patients. However, no three-year mortality rate differences were observed between the two groups. We also found a reduction in the complication and second-fracture rates.

Background/Objectives: Pycnodysostosis is a rare genetic disorder causing skeletal dysplasia. It is determined by a gene mutation leading to cathepsin K deficiency and predisposes a patient to osteosclerosis, resulting in increased bone fragility. The altered bone quality typical of this disease is responsible for an increased risk of fractures. The purpose of our study was to evaluate the orthopedic manifestations and potential pitfalls in the surgical treatments of pathological fractures in a series of patients treated in our institution who were affected by pycnodysostosis. Methods: We retrospectively evaluated clinical and radiographic characteristics of five patients with pycnodysostosis treated for pathological fractures at our hospital in the past 5 years. Results: Two male and three female patients were included in this study. Four patients had a family history of pycnodysostosis. All the patients were of short stature, but only two underwent growth hormone treatment. All the patients experienced fractures, mostly in their lower limbs and occurring as a result of low-energy trauma. Most of the patients experienced either consolidation delay or nonunion. Conclusions: The orthopedic management of fractures in patients with pycnodysostosis poses an ongoing challenge for orthopedic surgeons. The fact that the bone is simultaneously sclerotic and brittle makes any orthopedic surgical treatment challenging and at a high risk of nonunion in any case.
RESUMO
OBJECTIVES: This study aimed to estimate the incidence rate of re-fracture and all-cause mortality rate in patients with hip fractures caused by minor trauma in the first year following the event. MATERIALS AND METHODS: This is a retrospective cohort study of patients over 50 years of age conducted in a referral hospital located in Tehran (Shafa-Yahyaian). Using the hospital information system (HIS), all patients hospitalized due to hip fractures caused by minor trauma during 2013-2019 were included in the study. We investigated the occurrence of death and re-fracture in all patients one year after the primary hip fracture. RESULTS: A total of 945 patients with hip fractures during a 307,595 person-days of follow-up, were included. The mean age of the participants was 71 years (SD = 11.19), and 533 (59%) of them were women. One hundred forty-nine deaths were identified during the first year after hip fracture, resulting in a one-year mortality rate of 17.69% (95% CI: 15.06-20.77). The one-year mortality rate was 20.06% in men and 15.88% in women. Out of all the participants, 667 answered the phone call, of which 29 cases had experienced a re-fracture in the first year (incidence rate = 5.03%, 95% CI: 3.50-7.24). The incidence rates in women and men were 6.07% and 3.65%, respectively. CONCLUSION: Patients with low-trauma hip fractures have shown a high rate of mortality in the first year. Considering the increase in the incidence of hip fractures with age, comprehensive strategies are needed to prevent fractures caused by minor trauma in the elderly population.

BACKGROUND: Although percutaneous vertebral augmentation (PVA) is a commonly used procedure for treating vertebral compression fracture (VCF), the risk of vertebral refracture should be considered. Chronic kidney disease-mineral and bone disorder (CKD-MBD) is a systemic disease of mineral and bone metabolism. It is associated with an increased risk of fracture. Few studies have reported the use of PVA in patients with CKD-MBD. We herein report a rare case wherein the cemented vertebra and the adjacent vertebra refractured simultaneously in a CKD-MBD patient after PVA. CASE SUMMARY: A 74-year-old man suffered from low back pain after taking a fall about 3 wk ago. According to physical examination, imaging and laboratory findings, diagnoses of T12 VCF, CKD-MBD, and chronic kidney disease stage 5 were established. He then received percutaneous vertebroplasty at T12 vertebra. Fourteen weeks later, he presented with T12 and L1 vertebral refractures caused by lumbar sprain. Once again, he was given PVA which was optimized for the refractured vertebrae. Although the short-term postoperative effect was satisfactory, he reported chronic low back pain again at the 3-month follow-up. CONCLUSION: It is necessary that patients with CKD-MBD who have received PVA are aware of the adverse effects of CKD-MBD. It may increase the risk of vertebral refracture. Furthermore, the PVA surgical technique needs to be optimized according to the condition of the patient. The medium- and long-term effects of PVA remain uncertain in patients with CKD-MBD.
RESUMO
OBJECTIVE: We established an orthopedic ward fracture liaison services (OWFLS) model and evaluated its role in improving detection rates of bone metabolic markers, treatment rates, and long-term treatability. METHODS: This observational retrospective cohort study included 120 patients aged >50 years hospitalized for primary osteoporotic fracture from January 2018 to January 2019 (group A: not included in OWFLS). Group B (included in OWFLS) comprised 120 patients from February 2019 to February 2020. We compared rates of bone metabolic index testing, treatment, and adherence; symptomatic improvement; and recurrent fracture between groups. RESULTS: Rates of bone metabolism index testing (50% vs. 0%) and medication use (94.2% vs. 64.2%) were significantly higher after OWFLS implementation. There was no significant difference in adherence rates at 3 months between groups (97.3% vs. 93.5%). Adherence rates at 1 and 3 years were better in group B than A (73.5% vs. 51.9%; 57.5% vs. 26%, respectively). Recurrence of bone pain at 1 and 3 years was significantly lower in group B than A (20.4% vs. 46.8%; 45.1% vs. 76.6%, respectively). CONCLUSIONS: OWFLS improved the detection rate of bone metabolism indicators, treatment rate, and patient adherence and reduced recurrence of bone pain. OWFLS may be suitable for settings lacking human resources.

PURPOSE: To explore the effect of sarcopenia on recurrent fractures of adjacent vertebra after percutaneous kyphoplasty (PKP). METHODS: A total of 376 osteoporotic vertebral compression fractures (OVCFs) patients over 55 years old who were admitted to the Hospital from August 2020 to January 2021 were selected. Among them, 38 patients with recurrent fractures in adjacent vertebra after PKP were selected as the refracture group (RG), and the remaining 338 patients were selected as the non-refracture group (NRG). The age, gender, grip strength, body mass index (BMI), bone mineral density (BMD), visual analogue scale (VAS) of pain before and one month after surgery, Oswestry disability index (ODI) before and one month after surgery and the occurrence of sarcopenia were compared between the two groups. Logistic regression analysis was used to evaluate the effect of related risk factors on refracture after vertebral PKP. RESULTS: The results of t-test and Chi-square test showed that there were no obvious differences in gender, BMI, preoperative VAS score (t=-0.996, P = 0.320) and ODI (t=-0.424, P = 0.671), one month postoperative VAS score (t=-0.934, P = 0.355) and ODI score (t=-0.461, P = 0.645). while the age and grip strength showed significant differences between the two groups. Logistic regression analysis showed that BMI and gender had no significant effect on refracture after PKP, while sarcopenia and advanced age were independent risk factors for refracture after PKP. Also, increased BMD was a protective factor for refracture after PKP. CONCLUSION: Sarcopenia is an independent risk factor for recurrent fractures after PKP in OVCF patients. The screening and diagnosis of sarcopenia should be strengthened. At the same time, anti-sarcopenia treatment should be actively performed after surgery.

Objective: To analyze the causes and treatment of off target of the distal interlocking screws when short cephalomeduallry nails were installed through jig-guided targeting device, and to put forward the technical points to prevent off target. Methods: Retrospective analysis of 9 patients with intertrochanteric fractures treated between July 2014 and June 2023 was conducted, in which off target occurred during the insertion of the distal interlocking screw by jig-guided targeting device in short cephalomedullary nailling (<24 cm). There were 1 male and 8 females, with an average age of 82.7 years (range, 73-94 years). There were 3 cases of type A1, 5 cases of type A2, and 1 case of type A3 according to 2018-AO/Orthopaedic Trauma Association (AO/OTA) fracture classification. As for the misaligned distal interlocking screw, six parameters were collected and analyzed, including the time of finding, the position, the type of passing through the cortical bone, the special circumstances during operation (such as the need to remove the intramedullary nail for reaming the diaphysis, hammering, etc.), the treatment, and the patient follow-up results. Results: In the 9 patients, the off target of the distal interlocking screw was found in 7 cases during operation and in 2 cases after operation; the locking screw was located behind the nail in 7 cases and in front of the nail in 2 cases; the off target locking screw was passing tangentially in transcortical patern in 6 cases and in bicortical pattern through the medullary cavity in 3 cases. Three cases were attributed to the mismatch between the nail and the femur, two of which were attributed to the narrow femoral medullary cavity, one of which was attributed to the large anterolateral femoral bowing, and the other 6 cases were attributed to technical errors such as the loosening of the jig-guided targeting device, the tension of the fascia lata, and the blunt of the drill. In the 7 cases found during operation, the misaligned interlocking screw was removed first and the screw hole was left vacant, then in 2 cases, the interlocking screw was not used further; in 1 case, the distal dynamic hole was successfully inserted with a dynamic guide frame, and in 4 cases, the interlocking screw was successfully put after 2-3 attempts, leaving a large hole in the lateral cortex. No special treatment was performed in 2 cases found after operation. One patient was out of bed early after operation, 7 patients were in bed for 1 month, and 1 patient deteriorated to A3 type after operation and was in bed for 3 months. All the 9 patients were followed up 6-12 months, with an average of 8 months. Fracture healing was achieved in 8 patients. One patient with vacant interlocking screw had a secondary spiral fracture of the femoral shaft 3 months later, and was refixed with a long cephalomedullary nail and circlage wiring. Conclusion: Distal interlocking screw off target is rare, but when it occurs, it leaves a large cortical hole in the osteoporotic femoral shaft, reducing bone strength; the use of precision instruments and attention to technical details can reduce this adverse phenomenon.

PURPOSE: Refracture is one of the main complications of bone transport, which brings additional physical and mental burden to surgeries and patients. We aimed to raise a new classification system of refracture-related bone transport based on the Simpson classification and to present our experience on treatment. METHODS: This retrospective analysis included 19 patients with refracture-related bone transport (average age of 37.7 years; 18 men). We developed a modified Simpson classification system to assist decision-making (conservative versus surgical). The ASAMI criteria were used to assess the outcomes at last follow-up. RESULTS: The mean follow-up was 12.3 ± 3.2 months. Complete union was achieved in all patients, with no reinfection. Based on the modified Simpson classification, refracture was Ia type (within regeneration area) in three cases, Ib (collapsed fracture at the regeneration area) in one case, Ic (stress fracture) in three cases, II (at the junction between the regenerate and original bone) in one case, III (at the docking site) in nine cases, and V (at distant site) in two cases. Refracture was managed conservatively in six cases and surgically in 13 cases. Average time to bone union was 2.8 ± 1.2 months in the conservative group versus 4.4 ± 1.4 months in the surgery group. Assessment at the final follow-up using the ASAMI criteria revealed excellent bone result in all patients, excellent functional results in six patients (31.6%), and good functional results in 13 patients. CONCLUSIONS: The modified Simpson classification could include refracture at the docking site and stress fracture in the regeneration zone and provide some guidance in determining the appropriate treatment strategy.
