Long-Term Bone Density Changes and Fracture Risk in Myasthenia Gravis: Implications for FRAX® Tool Application.

Myasthenia gravis (MG) patients often require long-term glucocorticoid therapy, which may affect bone health. This study aimed to assess long-term changes in bone mineral density (BMD), evaluate osteoporotic fracture incidence, and examine the relationship between MG-specific factors and bone health outcomes over a 10-year period. This single-center, prospective cohort study included 28 MG patients. BMD, T-scores, Z-scores, and bone turnover markers were measured at baseline. FRAX® scores were calculated and adjusted for glucocorticoid dose. Fracture occurrence was monitored for over 10 years. Five (17.9%) patients experienced major osteoporotic fractures during follow-up. The fracture group had significantly lower baseline BMD and T-scores than the no-fracture group. Baseline FRAX® scores for major osteoporotic fracture risk were significantly higher in the fracture group (median 19.0% vs. 5.7%, p = 0.001). The fracture group progressed from osteopenia at baseline to osteoporosis by the end of this study. This study highlights the importance of early and regular bone health assessments in MG patients, particularly those receiving long-term glucocorticoid therapy. The FRAX® tool may be valuable for fracture risk stratification in this population. These findings can inform clinical practice and improve long-term management strategies for MG patients who are at risk of osteoporotic fractures.

The Conservative and Operative Treatment of Carpal Fractures.

Carpal fractures (incidence: 30-60 per 100 000 persons per year) are one of the more commonly overlooked fracture types. They can have serious consequences, as the use of the hand is indispensable in everyday life. In the following article, we present the elements of the diagnosis and treatment of fractures of the carpal bones. This review is based on meta-analyses and randomized controlled trials (RCTs) published from 2013 to 2023 that were retrieved by a structured literature search, supplemented by guideline recommendations and expert consensus statements. In addition, data on the administrative prevalence of carpal fractures were obtained from the German Association of Statutory Health Insurance Physicians (Kassenärztliche Vereinigung, KV) and from the German Statutory Accident Insurance (Deutsche Gesetzliche Unfallversicherung, DGUV). The administrative prevalence of carpal fractures in 2022 was 44 496 outpatient cases (KV, DGUV) in one year. After clinical history-taking, physical examination and x-ray have been performed, thin-slice computed tomography is recommended as part of the diagnostic evaluation. Treatment recommendations are based on evidence of levels II to IV. Multiple RCTs have been carried out on the treatment of scaphoid fractures, and a clinical guideline exists. Proximal, dislocated and unstable scaphoid fractures should be treated surgically. Non-displaced or minimally displaced fractures of the middle third of the scaphoid bone require a shorter period of immobilization with surgical treatment (2-4 weeks) than with conservative treatment (6-8 weeks). The use of plaster casts that do not hinder elbow and thumb mobility yields healing rates similar to those obtained with the immobilization of both of these joints. Failure to treat an unrecognized scaphoid fracture can lead to pseudarthrosis, avascular bony necrosis, and misalignment. Other, rarer types of carpal fractures must be managed on an individual basis, as the available evidence is limited to expert consensus. Early recognition and appropriate treatment of carpal fractures lead to healing in more than 90% of cases. Although the available evidence on their proper treatment is growing, many questions are subject to expert consensus, and decisions about treatment must be made individually.

Short-term risk of fracture is increased by deficits in cortical and trabecular bone microarchitecture independent of DXA BMD and FRAX: Bone Microarchitecture International Consortium (BoMIC) prospective cohorts.

Identifying individuals at risk for short-term fracture is essential to offer prompt beneficial treatment, especially since many fractures occur in those without osteoporosis by DXA-aBMD. We evaluated whether deficits in bone microarchitecture and density predict short-term fracture risk independent of the clinical predictors, DXA-BMD and FRAX. We combined data from eight cohorts to conduct a prospective study of bone microarchitecture at the distal radius and tibia (by HR-pQCT) and 2-year incidence of fracture (non-traumatic and traumatic) in 7327 individuals (4824 women, 2503 men, mean 69 ± 9years). We estimated sex-specific hazard ratios (HR) for associations between bone measures and 2-year fracture incidence, adjusted for age, cohort, height, and weight, and then additionally adjusted for FN aBMD or FRAX for major osteoporotic fracture. Only 7% of study participants had FN T-score ≤ -2.5, whereas 53% had T-scores between -1.0 and -2.5 and 37% had T-scores ≥-1.0. Two-year cumulative fracture incidence was 4% (296/7327). Each SD decrease in radius cortical bone measures increased fracture risk by 38%-76% for women and men. After additional adjustment for FN-aBMD, risks remained increased by 28%-61%. Radius trabecular measures were also associated with 2-year fracture risk independently of FN-aBMD in women (HRs range: 1.21 per SD for trabecular separation to 1.55 for total vBMD). Decreased failure load (FL) was associated with increased fracture risk in both women and men (FN-aBMD ranges of adjusted HR = 1.47-2.42). Tibia measurement results were similar to radius results. Findings were also similar when models were adjusted for FRAX. In older adults, FL and HR-pQCT measures of cortical and trabecular bone microarchitecture and density with strong associations to short-term fractures improved fracture prediction beyond aBMD and FRAX. Thus, HR-pQCT may be a useful adjunct to traditional assessment of short-term fracture risk in older adults, including those with T-scores above the osteoporosis range.

Posterior-anterior versus anterior-posterior screws for posterior malleolar fractures: A meta-analysis.

The incidence of posterior malleolus fractures in ankle fractures ranges from 7% to 44%. Studies have indicated a poorer prognosis for ankle joint function when a posterior malleolar fracture is present, underscoring the significance of active intervention for optimal postoperative ankle function recovery. Hence, the selection of treatment for such fractures holds particular importance. Screw fixation is a key treatment for posterior malleolus fractures (PMFs) or Haraguchi Type 1 fractures involving less than 25% of the distal tibia's articular surface. However, the optimal screw placement direction - anteroposterior (AP) or posterior-anterior (PA) - remains debated. This meta-analysis aims to compare these two approaches for treating posterior ankle fractures, focusing on the efficacy of PA fixation. We searched the Cochrane Library, EMBASE, PubMed, SinoMed, and Web of Science databases from their inception to October 20, 2022. Methodological quality was assessed using the Cochrane Collaboration's tool for assessing bias risk in randomized controlled trials (RCTs). Stata MP17 software was used to compare the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, full weight-bearing time, and fracture healing time at the last follow-up between the two fixation methods. A total of 403 patients with posterior malleolar fractures from six RCTs met the inclusion criteria. The meta-analysis revealed a higher AOFAS score at the last follow-up for PA placement compared to AP placement [SMD = 0.512, 95% CI (0.244 to 0.780), z= 3.74, P< 0.001]. Postoperative full weight-bearing time and fracture healing time did not show statistically significant differences between the two groups. PA fixation demonstrated a superior AOFAS score compared to AP fixation for posterior malleolar fractures. PA screw placement offers advantages in restoring ankle joint stability and enhancing joint function recovery post-surgery.

Effect of salt substitution on fracture—a secondary analysis of the Salt Substitute and Stroke Study (SSaSS)

BackgroundAssociations of dietary sodium and potassium intake with fracture risk are inconsistent and the effects of salt substitute on fracture incidence are unknown. We assessed the effect of salt substitute compared to regular salt intake on fracture incidence using data from the Salt Substitute and Stroke Study (SSaSS).MethodsSSaSS was a cluster-randomized controlled trial conducted in 600 villages in northern China. Villages were randomly allocated into intervention and control groups in a 1:1 ratio. Salt substitute was provided to intervention villages and control villages continued regular salt use for 5 years. The primary outcome for this secondary analysis was the incidence of all fractures. Secondary outcomes included incidence of vertebral fracture, non-vertebral fracture, and fracture of unknown or non-specific location.Results20,995 participants were included in this study, and 821 fractures occurred during follow-up. Intention-to-treat analyses showed no differences between the salt substitute and regular salt groups in the incidence of all fractures (rate ratio (RR) 0.96; 95% CI 0.81 to 1.14), vertebral fracture (RR 0.82; 95% CI 0.53 to 1.26), non-vertebral fracture (RR 1.05; 95% CI 0.86 to 1.29), or fracture of unknown or non-specific location (RR 0.80; 95% CI 0.54 to 1.18).ConclusionsUse of salt substitute compared to regular salt had no detectable effect on the incidence of fracture in a population at high risk of cardiovascular disease and fracture.Trial registrationClinicalTrials.gov, NCT02092090.

Anesthesia's Influence on Postoperative In-Hospital Morbidity-Mortality in Proximal Femoral Fractures in the Elderly.

Background and Objectives: The incidence of proximal femoral fractures (PFFs) is rising, causing significant morbidity and mortality. Regional anesthesia (RA)'s benefits include the avoidance of intubation and mechanical ventilation, decreased blood loss, and improved analgesia. General anesthesia (GA) offers improved hemodynamic stability. This study examines the in-hospital post-surgical morbidity and mortality seen in PFFs in a cohort of the elderly undergoing GA or RA. Materials and Methods: This is a retrospective cohort study of 319 PFF patients older than 65 years over a single year. Results: In total, 73.7% of patients underwent GA. The patient characteristics were identical between groups, except for smoking. Hypertension was the most frequent comorbidity, followed by hyperlipidemia, NIDDM, and IHD. The overall patient complication rate was 11.4%. Pneumonia was the most common complication (5.1% in GA, 8.4% in RA). A total of 0.9% of patients required ICU admission. Overall, the in-hospital mortality rate was 2.3%, with no statistically significant difference between GA and RA. The GA and RA cohorts were similar in terms of their patient demographics, medical history, and preoperative parameters. In total, 73% of surgeries were under GA. No statistically significant differences were found in total anesthesia time or complication rates. Conclusions: We did not find a difference between general and spinal anesthesia regarding complication rates, anesthesia time, or morbidity. General anesthesia remains best suited for patients receiving anticoagulation treatment and undergoing semi-urgent surgery, but, other than that, the mode of anesthesia administered remains up to the anesthesiologist's preference.

Trends in hip fracture rates in US male veterans.

In the United States, the annual incidence of osteoporotic hip fracture is estimated to be 250,000 to 300,000; the one-year mortality in some studies has been as high as 32%. Reports that hip fracture rates in US women 65years and older may no longer be declining led to this investigation of hip fracture in men, a less studied population. We assessed the trends in the incidence of hip fracture in US male veterans 50years and older of age as well as the rates of diagnosis and treatment in such men. We assessed the recent trends of hip fracture incidence in a nation-wide male veteran population 50years and older of age. Using data from the US Veterans Affairs Informatics and Computing Infrastructure (VINCI) 2002-2019, we calculated the annual age-standardized hip fracture incidence. Secondary objectives included evaluating the annual proportion of hip fracture patients who underwent dual-energy X-ray absorptiometry (DXA) before or after the fracture and/or received osteoporosis medication after the hip fracture over the study period. Hip fracture incidence increased in male veterans from 2006 to 2019. Fewer than 6% of men underwent a DXA scan and fewer than 0.5% received osteoporosis medications up to two years after a hip fracture. Despite available screening methods such as DXAs and medications for primary and secondary prevention of osteoporotic fractures, hip fracture incidence is not decreasing in older male veterans. Our study highlights a need for closerattention to fracture risk in men.

Related factors of severe osteoporotic vertebral compression fracture and clinical outcomes of percutaneous kyphoplasty: A retrospective study.

Osteoporosis is the most common disease in postmenopausal women and the elderly, which can lead to vertebral compression fracture. To investigate the related factors of severe osteoporotic vertebral compression fracture (SOVCF) and evaluate the long-term outcomes of percutaneous kyphoplasty (PKP) for treating SOVCF through comparison with mild OVCF (MOVCF). From September 2015 to March 2019, 294 osteoporotic vertebral compression fracture (OVCF) patients treated with PKP were analyzed. Compression of the anterior margin of the fractured vertebral body beyond 2/3 of the original height was defined as SOVCF. Baseline data, clinical and imaging findings before and after surgery and at the last follow-up were recorded. Numerical Rating Scale (NRS) was used to evaluate low back pain, the Oswestry Disability Index (ODI) was used to evaluate activity of daily life. Anterior vertebral height (AVH) and local kyphosis angle (LKA) was used to evaluate radiographic outcomes. During the follow-up, patients with recurrent back pain were examined by MRI to identify new fractures and the incidence of adjacent vertebral fracture (AVF) was recorded. Age, sex, body mass index (BMI), dual energy X-ray absorptiometry based T value, duration of symptom, history of trauma, steroid use, and fracture site were collected for univariate logistic regression analysis Variables with a P-value of less than 0.05 were then included in multivariate analysis to determine the related factors for SOVCF. Logistic regression analysis indicated that longer duration of symptom (OR = 1.109, 95%CI: 1.038-1.185, P= 0.002), lower T value (OR = 0.332, 95%CI: 0.139-0.763, P= 0.001), and steroid use (OR = 31.294, 95%CI: 1.020-960.449, P= 0.049) were related factors of SOVCF. Compared with the MOVCF group, the SOVCF group had longer operation time (57.3 ± 13.51 minutes vs 44.9 ± 8.13 minutes, P< 0.001), more radiation exposure (39.9 ± 7.98 times vs 25.5 ± 4.01 times, P< 0.001), and higher cement leakage rate (55.81% vs 18.73%, P< 0.001). At the last follow-up, the SOVCF group had higher NRS (2.28 ± 0.85 vs 1.30 ± 0.71, P< 0.001), and ODI (16.23 ± 4.43 vs 12.88 ± 3.34, P< 0.001). After operation and at the last follow-up, the SOVCF group had higher LKA and lower AVH (all P< 0.05). The AVF rate at the last follow-up was higher in the SOVCF group at the last follow-up (4.78% vs 18.60%, P< 0.001). Lower T value, longer duration of disease, and steroid use were related factors of SOVCF. Compared with MOVCF, PKP for SOVCF had longer operation time, more radiation exposure, and higher cement leakage rate, and the long-term outcomes were worsen.

Traumatic Dental Injuries among Adolescents and Young Adults in Iași, Romania: Legal and Medical Perspectives.

This study aims to assess the etiology, frequency, and localization of dental and periodontal trauma in adolescents and young adults, along with these individuals' predisposition based on age, gender, and residence. Materials and Methods This retrospective study included 109 adolescents and young adults from a database of the Emergency and Oral and Maxillofacial Surgery department at "Sf. Spiridon" Hospital, Iasi, Romania. The collected data included demographic details, mechanisms of dental and periodontal trauma, treatment approaches, and clinical outcomes. Statistical analysis was performed using SPSS 26.0, with comparisons based on age, gender, and residence. Enamel fractures (23.9%) and enamel-dentin fractures without pulp exposure (20.2%) were the most frequent dental injuries. Concussion (58.7%), subluxation (21.1%), luxation, avulsion (7.3%), and extrusion (5.5%) were common periodontal injuries. The anterior region of the dental arch accounted for the majority (60.6%) of injuries. Adolescents under 17 years were more prone to enamel-dentin fractures without pulp exposure (23.8%), enamel-dentin fractures with pulp exposure (20.6%), and root fractures (20.6%), while young adults over 18 years had a higher incidence of enamel fractures (32.6%) and crown-root fractures (30.4%). Falls (66.7%) were the predominant cause of trauma for female patients, whereas male patients were more often injured during sports activities (49.3%). The younger age group was 0.29 times more likely to sustain enamel-dentin fractures without pulp exposure (p = 0.049, OR = 0.291) and root fractures (p = 0.047, OR = 0.241). Traumatic dental injuries are more prevalent in young adults compared to adolescents, with falls and sports activities being the most common causes, particularly among males. These findings emphasize the need for targeted preventive programs aimed at reducing the incidence of dento-periodontal trauma in these age groups.

Fine Particulate Matter and Osteoporosis: Evidence, Mechanisms, and Emerging Perspectives.

Air pollution, particularly fine particulate matter with an aerodynamic diameter of ≤ 2.5 μm (PM2.5), has been recognized for its adverse effects on multiple organs beyond the lungs. Among these, the bone began to garner significant attention. This review covers epidemiological, animal and cell studies on PM2.5 exposure and bone health as well as studies on PM2.5-induced diseases with skeletal complications. Emerging evidence from epidemiological studies indicates a positive association between PM2.5 exposure and the incidence of osteoporosis and fractures, along with a negative association with bone mineral density. Experimental studies have demonstrated that PM2.5 can disrupt the metabolic balance between osteoclasts and osteoblasts through inflammatory responses, oxidative stress, and endocrine disruption, thereby triggering bone loss and osteoporosis. Additionally, this review proposes a secondary mechanism by which PM2.5 may impair bone homeostasis via pathological alterations in other organs, offering new perspectives on the complex interactions between environmental pollutants and bone health. In conclusion, this contemporary review underscores the often-overlooked risk factors of PM2.5 in terms of its adverse effects on bone and elucidates the mechanisms of both primary and secondary toxicity. Further attention should be given to exploring the molecular mechanisms of PM2.5-induced bone impairment and developing effective intervention strategies. With global climate change, increasing ozone pollution, emerging pollutants, and multifactorial exposure to environmental factors, these issues are likely to become of greater concern in the near future.

Incidence and Risk Factors of Sacral Fracture Following Lumbosacral Fusion for Degenerative Spinal Stenosis with a Minimum Follow-Up of 2 Years: A Case–Control Study

This study aimed to investigate the incidence and risk factors for sacral fractures following lumbosacral fusion. We conducted a retrospective review of patients who underwent lumbosacral fusion for degenerative spinal stenosis with a minimum follow-up of 2years. Patients who developed and those who did not develop a sacral fracture were categorized into the "sacral fracture" and "nonfracture" groups. The demographic and radiological data were compared between the 2 groups. A total of 65 patients were included in this study. Among them, 7 patients were categorized into the sacral fracture and 58 patients into the nonfracture groups, respectively. The incidence of sacral fracture was 10.8%. In the sacral fracture group, age and fusion levels were significantly higher (P<0.05), while bone mineral density (BMD) T-score was significantly lower (P<0.05) than nonfracture group. Pelvic incidence, preoperative pelvic tilt, postoperative sacral slope, and postoperative lumbar lordosis were significantly higher (P<0.05) in the sacral fracture than the nonfracture group. Multivariable logistic regression analysis showed that BMD T-score (odds ratio [OR] 0.25, 95% confidence interval [CI] 0.08-0.79, P=0.019), postoperative sacral slope (OR 1.14, 95% CI 1.00-1.29, P= 0.047), and changes in L4-S1 lordosis (OR 1.11, 95% CI 1.00-1.23, P= 0.049) were significant factors. The overall incidence of sacral fracture was 10.8%. In our study, advanced age, low BMD, long fusion levels, and preoperative compensatory pelvic retroversion and excessive correction of it were risk factors for sacral fractures.

Enzymatic and Non-enzymatic Collagen Cross-Links and Fracture Occurrence in Type 1 Diabetes Patients.

Increased fracture risk in type 1 diabetes (T1D) patients is not fully captured by bone mineral density (BMD) by DXA. Advanced glycation end-products (AGEs) have been implicated in the increased fracture risk in T1D, yet recent publications question this. To test the hypothesis that enzymatic collagen cross-links rather than AGEs correlate with fracture incidence in T1D, we analyzed iliac crest biopsies from sex-matched, fracturing T1D patients (N = 5; T1DFx), 6 non-fracturing T1D patients (T1DNoFx), and 6 healthy subjects, by Raman microspectroscopy as a function of tissue age (based on double fluorescent labels), in intracortical and trabecular bone, to determine pyridinoline (Pyd), ε-N-Carboxymethyl-L-lysine, and pentosidine (PEN)). There were no differences in the clinical characteristics between the T1DFx and T1DNoFx groups. At trabecular forming surfaces, T1DFx patients had higher PEN and Pyd content compared to T1DNoFx ones. Previous studies have shown that elevated PEN does not necessarily correlate with fracture incidence in postmenopausal, long-term T1D patients. On the other hand, the elevated Pyd content in the T1DFx patients would be consistent with published studies showing a significant correlation between elevated trivalent enzymatic collagen cross-links and fracture occurrence independent of BMD. Collagen fibers with high Pyd content are more brittle. Thus, a plausible suggestion is that it is the enzymatic collagen cross-links that either by themselves or in combination with the adverse effects of increased AGE accumulation that result in fragility fracture in T1D.

Socioeconomic and Demographic Determinants of Hip Fracture Incidence: A Comprehensive Analysis.

Hip fracture incidence is rising globally, making it crucial to understand the demographic factors that influence their occurrence for targeted healthcare interventions. This study focuses on examining the determinants of hip fracture incidence, particularly socioeconomic status, body mass index (BMI), and gender. The study utilised data from 570 patients recorded in the 2023 National Hip Fracture Database Audit tool. Socioeconomic status was assessed through the Index of Multiple Deprivation (IMD), based on patient postcodes. The analysis aimed to explore correlations between socioeconomic status, BMI, gender, and the incidence and types of hip fractures. The findings indicate that the majority of hip fractures occurred in individuals from the lowest socioeconomic deciles, with a statistically significant correlation (p < 0.05) between lower socioeconomic status and higher fracture incidence. Gender-specific disparities were observed, with males experiencing fractures at younger ages and presenting with different fracture types compared to females. Additionally, lower BMI was significantly associated with a higher likelihood of certain fracture types (p < 0.05). The study highlights the substantial influence of socioeconomic status, gender, and BMI on hip fracture incidence and typology. These results indicate the need for targeted prevention strategies and health policies aimed at mitigating hip fracture risks in socioeconomically disadvantaged populations. Understanding these factors can enable healthcare providers to allocate resources and interventions more effectively, reducing the incidence and impact of hip fractures in deprived areas.

Schatzker IV tibial plateau fractures: are they always unicondylar?

The objectives of this study were to describe the incidence and morphology of medial tibial plateau fractures that extend into the lateral articular surface and to describe trends in their management. Retrospective. Level I Urban Trauma Center. Seventy consecutive patients sustaining OTA/AO 41 B1 and B3 fractures. Open reduction internal fixation of medial tibial plateau fractures. Incidence of medial tibial plateau fractures that extend into the lateral articular surface. Secondary outcomes include localization of lateral articular surface depression, neurovascular injury, and trends in surgical management. Seventy patients were included with 9 fractures (12.9%) isolated to the medial condyle (MC) and 61 fractures (87.1%) extending to the lateral condyle (LC). Compartment syndrome was present in 2 patients (2.9%), peroneal nerve palsy in 2 (2.9%), and arterial injury in 1 (1.4%). Initial external fixation was used more frequently in the LC group compared with the MC group (P = 0.028). Of the 61 fractures in the LC group, 49 (80.3%) included lateral articular surface depression which localized to the posteromedial quadrant of the lateral articular surface in 36 of 49 fractures (73.5%). Lateral articular surface depression depth ≥10.6 mm was associated with the use of dual incisions (P < 0.001). Schatzker IV fractures frequently extend to the lateral condyle and often present with depression of the posteromedial lateral articular surface. Fractures with lateral articular surface depression depth ≥10.6 mm were more likely to undergo fixation with dual incisions. Therapeutic level IV.

Integrating traditional Chinese Medicine reduced the risk of hip fracture in patients with dementia

Background/purposeThe high incidence of hip fracture is an important problem among dementia patients because of their higher risk of falls and balance deficits due to a lack of physical activity. The aim of this study was to investigate whether traditional Chinese medicine (TCM) therapy could reduce the risk of hip fracture in dementia patients. MethodsWe identified 38,071 patients who were first diagnosed with dementia from January 1, 2000, to December 31, 2017, from the database of the 2000 Longitudinal Generation Tracking Database (LGTD 2000) provided by the Health and Welfare Data Science Center (HWDC) in Taiwan. Patients who received TCM treatment after the initial diagnosis of dementia were assigned to the TCM group, and patients who never received TCM treatment were assigned to the non-TCM group. After performing 1:1 propensity score matching (1:1) based on age, sex, comorbidities and medication between the TCM and non-TCM groups, there were 902 patients in each group. Patients were followed up to December 31, 2018, and incidences of hip fracture after the initial diagnosis of dementia between the two groups were compared with Cox regression analysis. ResultsNinety-four patients in the non-TCM group (10.42%) and 58 patients in the TCM group (6.43%) suffered from hip fracture during the follow-up period. Patients in the TCM group had a lower incidence of hip fracture than those in the non-TCM group (adjusted hazard ratio = 0.54, 95% confidence interval = 0.38–0.76). ConclusionsIntegrating TCM health care for dementia patients might reduce the risk of hip fracture.

Combined Medial Patellofemoral Ligament Reconstruction and Tibial Tubercle Osteotomy Has a Lower Risk of Recurrent Instability Requiring Revision Stabilization at 2 Years Than Either Procedure Alone

PurposeThe goal of this study was to utilize a large nationwide administrative database to directly compare usage, complications, and need for revision stabilization surgery after medial patellofemoral ligament reconstruction (MPLFR), tibial tubercle osteotomy (TTO), and combined MPFLR and TTO (MPFLRTTO). MethodsThe PearlDiver Mariner database was queried for all reported cases of MPLFR, TTO, and combined MPFLR and TTO performed between 2010 and 2020 using Current Procedural Terminology codes. Subsets from those cohorts with laterality-specific International Classification of Diseases, Tenth Revision codes for patellar instability were used to evaluate 2-year incidence of infection, stiffness, fracture, and revision stabilization with MPFLR and/or TTO. Multiple Linear regression and chi-squared analysis were used to analyze incidence trends and to compare complication rates. ResultsA total of 70,070 patients were identified. MPFLR was found to be the most common procedure (73.1%) followed by TTO (19.2%) and then MPFLRTTO (7.6%). MPLFR was observed to have the lowest overall complication rate (5.4%), while both TTO (7.5%) and MPFLRTTO (7.1%) had higher complication rates (P<.001). MPFLR had the highest rate of revision stabilization surgery at 3.7% compared with TTO at 2.7% and MPFLRTTO which carried the lowest risk for revision at 2.4% (P<.001). ConclusionIsolated MPFLR is the most common modality used for patellar instability, with increasing prevalence and the lowest 2-year complication rate. Isolated tibial tubercle osteotomy was unchanged in its utilization and had the highest overall complication rate. Combined MPFLR and TTO increased the overall complication rate but had a lower 2-year rate of recurrent instability requiring revision than MPFLR alone.

Fracture Non-Union in Osteoporotic Bones: Current Practice and Future Directions.

Given the compromised bone quality and altered healing environment, fracture non-union in osteoporotic bones presents a complex challenge in orthopedics. As global populations age, the incidence of osteoporotic fractures rises, leading to increased delayed healing and non-union cases. The pathophysiology underlying non-union in osteoporotic patients involves impaired bone regeneration, reduced osteoblast function, and poor vascularity. Traditional management strategies - ranging from pharmacological interventions like bisphosphonates and teriparatides to surgical approaches such as bone grafting and mechanical fixation - often yield limited success due to the weakened bone structure. Recent advances, however, have introduced novel therapies such as growth factors, stem cell applications, gene therapy, and bioactive scaffolds that offer more targeted and biologically driven solutions. Emerging technologies like three-dimensional printing and nanotechnology further contribute to customized treatment strategies that hold promise for improved outcomes. Diagnostic approaches have also evolved, integrating radiological assessments and biomarkers to identify patients at risk for non-union better. Despite these advancements, challenges remain, including the high costs, technical complexities, and the need for more robust clinical evidence. Future directions involve optimizing these innovative treatments, validating their effectiveness in more extensive clinical trials, and integrating personalized medicine approaches to cater to the individual needs of osteoporotic patients. Overall, integrating these emerging therapeutic strategies alongside traditional practices represents a significant shift towards more effective and personalized management of fracture non-union in osteoporotic bones.

Increased Risk of 10-Year Revision Following Total Hip Arthroplasty for Femoral Neck Fracture

BackgroundAs the incidence of femoral neck fractures (FNFs) increases with the aging population, understanding its impact on surgical outcomes is important to improving implant survival and patient satisfaction. Despite increasing use of total hip arthroplasty (THA) as management for FNF, few studies have examined long-term implant survivability. Thus, this study sought to determine the 10-years cumulative incidence of revision and indications for revision in patients undergoing THA for FNF in comparison to osteoarthritis. MethodsPatients who underwent primary THA for FNF or osteoarthritis were identified using a national administrative claims database and propensity-score matched in a 1:2 ratio based on age, gender, the Charlson Comorbidity Index (CCI), smoking, obesity, and diabetes mellitus. Kaplan-Meier and Cox proportional hazards analyses were used to observe the cumulative incidence and risk of all-cause revision, periprosthetic joint infection (PJI), dislocation, mechanical loosening, and periprosthetic fracture (PPF) within 10 years of primary THA. In total, 19,735 patients who underwent THA for FNF and 39,383 patients who underwent THA for osteoarthritis were included. ResultsThe 10-years cumulative incidences of all-cause revision (7.1 versus 4.9%), PJI (5.0 versus 3.3%), dislocation (6.8 versus 3.8%), mechanical loosening (3.1 versus 1.9%), and PPF (7.8 versus 4.0%) were significantly higher for those who underwent THA for FNF versus osteoarthritis. Femoral neck fractures were associated with higher risks of revision (hazard ratio [HR]: 1.6), PJI (HR: 1.7), dislocation (HR: 2.0), mechanical loosening (HR: 1.6), and PPF (HR: 2.2) (P < 0.001 for all). ConclusionsDespite the advantages of THA, femoral neck fractures remain a major risk factor for long-term complications. Tailored preoperative planning, surgical techniques, and postoperative bone health optimization in these patients may help minimize poor outcomes.

Epidemiology of American Football-Related Fractures in the United States 2002-2021.

American football is the most popular sport in the United States, with over 5.6 million people >6 years old playing the sport. Fractures in American football athletes are significant, as they compromise an athlete's performance and can also lead to prolonged recovery periods, affecting team dynamics and player careers. Analyzing these injuries is critical to evaluate preventive measures and tailor rehabilitation strategies to ensure the well-being and sustained peak performance of football athletes on and off the field. To analyze the trend of American football fractures by body site, sex, and age in amateur athletes over a 20-year period between 2002 and 2021. Descriptive epidemiology study. The National Electronic Injury Surveillance System (NEISS) database was queried to characterize football-related fractures and injuries from 2002 to 2021 in patients aged 0-99 years old. National injury estimates were calculated using sample weights. Chi-square analysis and one-way ANOVA were performed to compare categorical variables. Of 56,809 cases of American football-related fractures over 20 years, patients aged 10 to 14 years had the highest incidence of fractures, composing 41.2% of all fractures (n = 23,389), and patients aged <18 years represented 88.8% of all fractures (n = 50,457). The median age of players when fractures occurred was 13 years. Upper extremity fractures (n = 41,863 [73.7%]) were the most common fracture reported compared with lower extremity and head, neck, and trunk fractures. Among upper extremity fractures, finger fractures had the highest prevalence (35.6%), followed by lower arm fractures (19.9%) and wrist fractures (13%). While most cases resulted in release after treatment (93.1%), 5.9% resulted in treatment and hospitalization. When analyzing trends in American football-related fractures over time, we observed the largest number of fractures in 2006 (n = 3664), while the smallest number of fractures occurred in 2020 (n = 1313). Also, a downward trend was found in American football-related fractures since 2006, with a mean of 101 fewer fractures each year. Our analysis showed that American football-related fractures diagnosed in the emergency department in the United States were most likely to occur in pediatric patients (10-18 years old). In addition, patients experiencing American football-related fractures were most likely to have an upper extremity fracture and not require hospitalization. The trend in American football-related fractures has been decreasing since 2006.

Teriparatide in postmenopausal osteoporosis: uncovering novel insights into efficacy and safety compared to other treatments - a systematic review and meta-analysis.

The aim of the study was to evaluate the efficacy and safety of teriparatide compared to other treatments for postmenopausal osteoporosis. A review of studies from 2000 to January 2023 analyzed randomized controlled trials on postmenopausal women treated with teriparatide (PTH 1-34), comparing it to placebo or other osteoporosis treatments. The analysis focused on bone mineral density (BMD), bone turnover markers, and clinical outcomes, employing Review Manager 5.4.1 and the RoB 2 tool for bias assessment. Our analysis of 23 randomized controlled trials (RCTs) found that PTH (134) treatment significantly increased lumbar spine BMD (mean difference (MD) = 0.02, 95% CI: 0.01-0.03) and femoral neck BMD (MD = 0.01, 95% CI: 0.00-0.01). However, there were no significant changes in total hip and radial bone BMD among the 3536 and 2046 participants, respectively. We also found that PTH (1-34) increased P1NP in a larger cohort (n = 1415) when compared to osteocalcin (n = 206). Although the risk of adverse events increased (relative risk (RR) = 1.65, 95% CI: 1.32-2.07), the incidence of fractures decreased significantly (RR = 0.57, 95% CI: 0.45-0.072), with no significant difference observed in mortality rates between treatment and control groups. Teriparatide improves lumbar spine and femoral neck BMD in postmenopausal women. Particularly notable is the novel finding regarding its effect on radius BMD, an area less explored in previous research. Despite an uptick in adverse events, the marked decrease in fracture incidence confirms its clinical utility for high-risk osteoporosis patients, highlighting the necessity for ongoing investigations into its full skeletal effects.
