Finite Element Analysis and Clinical Applications of Transverse Post for the Rehabilitation of Endodontically Treated Teeth.

Introduction The preservation of tooth structure during cavity preparation is crucial for maintaining tooth strength and longevity of restorations. The biomechanical behavior of teeth, especially those with mesio-occlusal-distal (MOD) cavity preparations, is significantly affected by the extent of cavity preparation and the type of restorative treatment employed. The aim of the current study was to evaluate and analyze the stress distribution seen in the mandibular molar with MOD cavity when restored with transverse post, using finite element analysis (FEA). Materials and methodology FEA was utilized to evaluate stress distribution in an endodontically treated mandibular first molar with MOD cavity preparation, restored using a transverse post and composite restoration. Three-dimensional models incorporating the tooth and the surrounding structures, along with the transverse post and composite restoration, were constructed based on known biomechanical properties. After meshing the models, loads were defined on the buccal and lingual cusps with a constant value of 600N and at an angle of 45 degrees. Preprocessing involved model preparation followed by postprocessing to obtain results representing the degree and type of stress distribution. Results FEA simulations revealed the distribution of stress within the tooth structure under functional occlusal forces. The transverse post system effectively reinforced the tooth by deflecting incident forces and providing uniform stress distribution. von Mises stresses were analyzed to assess the likelihood of material failure. The distribution of the stress in the restored tooth model was comparable to that seen in the intact model. Conclusion Transverse post along with composite restoration provides a conservative and cost-effective alternative to full coverage crowns while providing a functional and aesthetic outcome. Further research and clinical studies are warranted to validate these findings and optimize the clinical application of transverse post systems in restorative dentistry.

Two-Step Conservative Surgery for Complicated Forms of Diabetes-Related Foot Osteomyelitis.

Diabetes-related foot osteomyelitis (DFO) is a common yet complex condition, often complicated by concurrent soft tissue infections (STIs). This study evaluates the efficacy of a two-step conservative surgical approach, hypothesizing that it offers comparable outcomes to a one-step procedure. Conducted on a cohort of 93 patients with DFO, the study categorized cases into two types: OM1 (osteomyelitis without STI) and OM2 (osteomyelitis with STI). OM2 was further subdivided into OM2a (early diagnosis) and OM2b (late diagnosis), with OM2 patients undergoing initial soft tissue debridement followed by elective bone surgery. The results indicated no significant differences in infection recurrence or amputation rates between the two surgical approaches, with recurrence observed in 20.7% of cases and amputations in 10.8%. The two-step procedure was associated with higher inflammatory responses and greater need for antibiotics and hospital admissions. However, these factors did not translate into increased recurrence or amputation compared to the one-step procedure. The study supports the two-step approach as a safe and effective method for managing complicated DFO cases, providing a viable alternative to immediate amputation or single-stage surgery. Despite some limitations, including regional specificity and potential underdiagnosis in late-diagnosed cases, the findings offer valuable insights for clinical management and suggest further research to refine treatment protocols. The study's strengths include confirmed histopathological diagnoses and consistent follow-up, reinforcing the validity of the two-step surgical approach for complex DFO treatment.

Ten-year minimal follow-up of lateral opening wedge distal femoral osteotomy for lateral femorotibial osteoarthritis: Good survivorship and high patient satisfaction.

PURPOSE: This study aimed (1) to determine complications and survival rates of lateral opening wedge distal femoral osteotomy (LOW-DFO) in the long term, (2) to assess their clinical outcomes in the long term and (3) to identify risk factors of failure. METHODS: Between 1991 and 2011, 62 LOW-DFOs were performed in the same department. Inclusion criteria were all isolated LOW-DFO performed for isolated lateral tibiofemoral osteoarthritis and valgus malalignment, with a minimum 10-year follow-up. Thirty-eight patients were included, with a mean age of 48 ± 9 years. All patients had clinical and radiological assessments. The survival curves were calculated based on the following endpoints: unicompartmental or total knee arthroplasty. RESULTS: The mean follow-up was 15.2 ± 4.4 [10-29] years. The mean preoperative mechanical FemoroTibial Axis (mFTA) was 188.8° ± 3.2° [184°-197°], primarily due to femur deformity (mean lateral distal femoral axis [LDFA] 83.2° ± 2.8°). Bone union was achieved in 89.5% of patients (n = 34) at a mean delay of 6.5 ± 6.7 months. The complication rate was 26% (five stiffness, one nonunion, three secondary displacements and one deep vein thrombosis). Nine revision surgeries (24%) were recorded. Survival rates at 5 and 10 years were 92.1% and 78.9%, respectively. The mean delay between DFO and total knee arthroplasty (TKA) was 11.6 ± 5.7 [1-27] years. Nineteen patients (50%) were free of TKA at the last follow-up. KSS scores were improved significantly. Return to sports was obtained in 92% of cases (n = 35), with a mean delay of 11 ± 8 months. Seventy-four per cent of patients were satisfied or very satisfied with the surgery. Eighty-four per cent would be willing to undergo the surgery again. Older age (p = 0.032) was a significant risk factor for TKA conversion. CONCLUSION: LOW-DFO is an efficient procedure to manage lateral knee osteoarthritis in young patients with valgus deformity, with a good survival rate at 10 years and high patient satisfaction. LEVEL OF EVIDENCE: Level III.

Evaluating the association of radiographic parameters of proximal humerus fractures managed conservatively with functional outcomes.

INTRODUCTION: Treatment of proximal humerus fractures remains controversial. Understanding the factors that can affect the long-term functional outcomes can aid with management choices. This primary aim of this paper is to evaluate the association of radiographic parameters with functional outcomes. METHODS: Radiographic parameters [Caput-collum-diaphyseal (CCD) angles, Y-scapular angles, and humeral head height (HHH)] were studied. The patients were split into varus and valgus groups based on the CCD angles and retroverted and anteverted groups based on Y-scapular angles. Functional outcome was measured by Oxford Shoulder Score (OSS), Constant Shoulder Score (CSS), and quick Disabilities of Arm, Shoulder and Hand score at 1 year follow-up. Intra- and interrater reliability were measured with the intraclass correlation coefficients (ICCs). Receiver operator curve (ROC) analysis and logistic regression analysis defined the optimal value for abnormalities on radiographic evaluation as an outcome predictor. RESULTS: 111 patients were recruited (mean age 69, 78% female). Median final radiographic assessment was at 7 months. Mean initial/final CCD was 119o /111o (varus, n = 36) and 153o/140o (valgus, n = 75). Mean initial/final Y-scapula angle was 27o/27o (retroversion, n = 101) and 70o/40o (anteversion, n = 9). There was a significant relationship between OSS and final Y-scapular angle in the retroverted group (adj coeff 0.034, p = 0.009) with optimum predictive retroversion angulation of 25o predicting poor functional outcome (OSS < 40), area under the ROC curve of 0.614. Higher initial valgus and retroversion significantly predicted more change in the final angle (adj coeff - 0.349, p = 0.002, adj coeff - 0.527, p < 0.001 respectively). Both intra-rater and inter-rater reliability for the radiographic parameters were excellent (ICC > 0.9). CONCLUSION: Radiographic parameters whilst having excellent reliability, have a limited ability to predict short-term functional recovery. The extent of retroversion is the most important predictor for functional recovery with 25o a cut-off guide. Fractures with a higher initial valgus and retroversion tend to displace more.

Intramedullary nailing of proximal humerus fractures does not achieve superior functional results to non-operative treatment in the long term.

INTRODUCTION: Non-operative treatment (NOT) of proximal humerus fractures (PHF) has regained significance due to recent evidence. Additionally, positive outcomes of plate osteosynthesis and fracture arthroplasty prompt a reassessment of the role of intramedullary nailing (IMN). While favorable short and medium-term results have been documented following IMN, little is known regarding functional outcomes and quality of life in the long-term. METHODS: Data from 180 patients with dislocated PHF of Neer types III, IV and V, treated at our level-I trauma center between 2004 and 2014 using IMN or NOT therapy, were scanned. Patients were re-evaluated after a minimum of 5 years to assess functional outcomes (age- and sex-adapted Constant Score, QuickDASH), quality of life (SF12), and complications or reoperations. RESULTS: Out of the initially identified 180 patients, 51 were unavailable for follow-up (FU) and 71 had deceased during the FU period. Functional outcomes and quality of life was, therefore, assessed in 58 patients (30 IMN, 28 NOT) with an average age at injury of 68 years after a mean FU time of 10.3 ± 3.4 years. Epidemiological patient characteristics did not exhibit significant differences between the two groups (p > .05). The functional outcome assessed by age- and sex-adapted Constant Score (NOT: 74 ± 28; IMN: 68 ± 24; p = .438), QuickDASH (NOT: 25 ± 27; IMN: 31 ± 23; p = .374) or quality of life using the SF12 (p > .05) revealed no significant disparities in long-term outcomes between the treatment groups. 10 of 30 patients in the IMN group underwent surgical revision to address complications, exceeding mere implant removal. Conversely, no patient in the NOT group underwent a revision surgery during the FU period. CONCLUSIONS: In the long-term, functional and quality of life-related outcomes of IMN did not diverge significantly from those of NOT, while causing a higher incidence of follow-up interventions.

Epididymal cysts in children: frequency, clinical characteristics, and management strategies.

Background: Epididymal cysts (ECs) are uncommon in the pediatric population. The objective of this study was to evaluate the frequency, clinical characteristics, and management strategies of ECs in children. Methods: We performed a retrospective review of pediatric scrotal ultrasounds between January 2014 and August 2022 to identify children with ECs. Results: One hundred and forty-three children boys were found to have ECs, with 95 being pre-pubertal and 48 post-pubertal. The age of the patients ranged from 1 day to 18 years, with a mean age of 10.64 ± 4.55 years. The size of the cysts varied from 2 mm to 35 mm. The most common comorbidities observed were hydrocele, testicular microlithiasis and varicocele. The majority of ECs were detected through routine physical examination. Conservative management was employed for all patients, except for one who required surgical excision. Resolution of ECs occurred in 12 patients, while a reduction in cyst size was observed in 6 cases. Conversely, 2 patients experienced an increase in cyst size, and 6 patients exhibited an increase in cyst number during the follow-up period. Conclusion: Conservative management is the preferred approach for the majority of cases, with surgical intervention reserved for specific instances.

Isolated bladder training or in combination with other therapies to improve overactive bladder symptoms: a systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Bladder training (BT), the maintenance of a scheduled voiding regime at gradually adjusted intervals, is a common treatment for overactive bladder (OAB). OBJECTIVES: To assess the effects of isolated BT and/or in combination with other therapies on OAB symptoms. METHODS: A systematic review of eight databases was conducted. After screening titles and abstracts, full texts were retrieved. Cochrane RoB 2 and the GRADE approach were used. RESULTS: Fourteen RCTs were included: they studied isolated BT (n = 11), BT plus drug treatment (DT; n = 5), BT plus intravaginal electrical stimulation (IVES; n = 2), BT plus biofeedback and IVES (n = 1), BT plus pelvic floor muscle training and behavioral therapy (n = 2), BT plus percutaneous tibial nerve stimulation, and BT plus transcutaneous tibial nerve stimulation (n = 1). In a meta-analysis of short-term follow-up data, BT plus IVES resulted in greater improvement in nocturia (mean difference [MD]: 0.89, 95% CI: 0.5, 1.20), urinary incontinence (UI; MD: 1.93, 95% CI: 1.32, 2.55), and quality of life (QoL; MD: 4.87, 95% CI: 2.24, 7.50) than isolated BT, while DT and BT improved UI (MD: 0.58, 95% CI: 0.23, 0.92) more than isolated BT. CONCLUSION: In the short term, BT plus IVES improves the OAB symptoms of nocturia and UI while improving QoL. The limited number of RCTs and heterogeneity among them provide a low level of evidence, making the effect of BT on OAB inconclusive, which suggests that new RCTs should be performed.

A unique intersection: Exploring an exophytic, pedunculated hepatic hemangioma with gastric connection in a case report.

Hepatic hemangiomas are commonly benign liver tumors, typically asymptomatic and predominantly located in the right lobe. This case report details an exceptional instance of a left-lobe hepatic hemangioma manifesting as an exophytic, pedunculated mass resembling a gastric tumor. A 77-year-old woman with a history of melanoma presented with a mass incidentally discovered during evaluations for chest pain. Advanced imaging techniques, including computed tomography (CT) and endoscopic ultrasound (EUS), identified this mass as a benign, pedunculated hemangioma extending from the left hepatic lobe toward the gastric fundus. Given the tumor's benign nature and the patient's lack of symptoms, a conservative management approach was adopted. This case emphasizes the importance of accurate imaging and diagnostic assessment in managing atypical hepatic hemangiomas, highlighting the need to carefully consider rare growth patterns and locations in differential diagnoses to avoid unnecessary interventions. Such cases reinforce the complexity of diagnosing and managing unusual presentations of common benign tumors.

Spontaneous isolated superior mesenteric artery dissection: an investigative case report.

Spontaneous isolated superior mesenteric artery dissection (SISMAD) is a rare cause of acute abdominal pain, but could potentially be fatal to patients, and should be recognized soon in the emergency department after excluding other common causes. Computed tomography (CT) is the modality of choice for initial diagnosis and follow-up. Currently there is no evidence-based guidelines for managing SISMAD. A 58-year-old man being suspected of a mesenteric artery dissection was referred to our emergergy department. The patient was monitored, treated conservatively with anticoagulant and discharged after 3 days. Follow-up CT scans at 6 month, 1 year and 1 year and a half post discharge showed a partially occluded false lumen, the diameter of true lumen had increased in size and no signs of bowel ischemia. SISMAD should be considered as part of differential diagnoses when patients in their fifth to seventh decades of life present with acute abdominal pain. Treatment includes conservative management, percutaneous endovascular interventions, or surgery, but most patients can be managed conservatively.

Exploring factors affecting activities of daily living in patients with osteoporotic vertebral fractures managed conservatively: a post-hoc analysis of a prospective cohort study.

Study Design: A post-hoc analysis of a prospective cohort study. Purpose: This study aimed to identify factors at the time of injury associated with declining activities of daily living (ADLs) in the chronic phase of osteoporotic vertebral fractures (OVFs) managed conservatively. Overview of Literature: Although a conservative approach is the treatment of choice for OVFs, ADLs do not improve or eventually decrease in some cases. However, the risk factors for ADL decline after the occurrence of OVFs, particularly the difference between those with or without initial bed rest, are unknown. Methods: A total of 224 consecutive patients with OVFs aged ≥65 years who received treatment within 2 weeks after the occurrence of injury were enrolled. The patients were followed up for 6 months thereafter. The criteria for evaluating the degree of independence were applied to evaluate ADLs. Multivariable analysis with a logistic regression model was performed to evaluate the risk factors for ADL decline. Results: In total, 49/224 patients (21.9%) showed a decline in ADLs. Of these, 23/116 patients (19.8%) in the rest group and 26/108 patients (24.1%) in the no-rest group experienced a decline in ADLs. In the logistic regression analyses, a diffuse low signal on T2- weighted magnetic resonance imaging (MRI) (odds ratio, 5.78; 95% confidence interval, 2.09-16.0; p=0.0007) and vertebral instability (odds ratio, 3.89; 95% confidence interval, 1.32-11.4; p=0.0135) were identified as independent factors in the rest and no-rest groups, respectively. Conclusions: In patients with acute OVFs, a diffuse low signal on T2-weighted MRI and severe vertebral instability were independently associated with ADL decline in patients treated with and without initial bed rest, respectively.

Post-Myocardial Infarction (MI) Left Ventricular Free Wall Rupture Managed Conservatively.

Left ventricular free wall rupture (LVFWR) is an uncommon but often fatal complication of acute myocardial infarction. LVFWR is managed with hemodynamic stabilization and is typically followed by surgical intervention with varying approaches depending on the type of LVFWR. A 78-year-old male with a history of coronary artery bypass graft (CABG) was admitted with ST-segment elevation myocardial infarction. Left heart catheterization showed complete occlusion of the saphenous vein graft to the 1st obtuse marginal artery. The patient was not a candidate for percutaneous coronary intervention or CABG. The patient later developed atrial fibrillation with a rapid ventricular response which was managed with beta blockers. Computed tomography pulmonary angiogram was done to rule out pulmonary embolus; however, it demonstrated findings of a lateral LVFWR. The patient was deemed a poor surgical candidate for cardiothoracic surgery, and the LVFWR was managed conservatively with metoprolol succinate and bed rest. He later required amiodarone and direct current cardioversion due to the recurrence of atrial fibrillation. Two months following the LVFWR, the patient remained stable with no apparent complications. In a certain subset of LVFWR patients, surgical management may not be possible given patient anatomy and other high-risk factors. In these cases, conservative management with bed rest and beta blockers and treatment of ventricular and atrial arrhythmias may be a viable therapeutic option.

Factors Associated With Ambulation Status and Survival One Year After Conservative Management of Hip Fracture.

PURPOSE: Few studies have investigated the factors associated with ambulation and survival over one year. Therefore, this study aimed to examine the factors that influence ambulation and survival rates in elderly patients who have undergone conservative management for hip fractures. MATERIALS AND METHODS: This retrospective study included 74 ambulatory individuals aged 65 years or older prior to their injuries. One-year mortality and ambulatory status were assessed. Statistical comparisons of background and medical characteristics between groups of independent and non-independent walkers, as well as between survivors and mortalities, were performed using the Pearson chi-squared, Fisher exact, and Mann-Whitney U tests. RESULTS: The numbers of older patients able to walk independently, those not able to walk independently, and those with mortality at one-year post-injury after conservative management of hip fractures were 13 (18.3%), 35 (49.3%), and 23 (32.4%), respectively. Independent walkers one year after conservative treatment for hip fracture were younger (p=0.04) and less likely to have cognitive impairment (p=0.04) than non-independent walkers. The proportion of individuals with cognitive impairment was found to be lower among survivors than among mortalities (p=0.0098). CONCLUSION: Cognitive decline may contribute to difficulties in walking independently and mortality at one year post-injury in this population.

A Professional Basketball Player Who Suffered an Open Ankle Dislocation Without an Associated Fracture Achieves His Prior Performance Level Three Months Later.

An ankle dislocation without an accompanying fracture is extremely rare, and an open ankle dislocation is even rarer. Due to its rarity, there is no consensus on the optimal treatment strategy. A professional basketball player (a 28-year-old male) incurred an open ankle dislocation (with no accompanying fracture) during a basketball game due to plantar flexion and inversion of his ankle during the transition from dashing to stop motion. The same day, an emergency reduction under spinal anesthesia was performed with primary closure of the wound. Considering the complications of infection and decreased ankle range of motion (ROM), primary ligament repair was not performed. He was treated conservatively with cast immobilization for four weeks, and early weight-bearing and ROM exercises were initiated. At six weeks postoperatively, stress radiography did not reveal ankle instability. After three months of conservative treatment, the patient was able to play basketball at his previous performance level. Four weeks of cast immobilization without ligament repair plus early rehabilitation with weight-bearing and ROM exercises allowed for an early return without complications. Even in high-level athletes, open ankle dislocation without an accompanying fracture can be treated adequately with conservative therapy.

Interval operative management in patients admitted with acute obstruction due to incarcerated paraesophageal hernia.

BACKGROUND: Acute incarcerated paraesophageal hernias (PEH) have historically been considered a surgical emergency. Emergent operations have a higher rate of morbidity and mortality compared to elective surgery. Our institution has adopted a strategy of initial conservative management in patients presenting with acute obstruction from an incarcerated PEH who are clinically stable. Patients are given at least 24 h for their symptoms to improve (selective nasogastric decompression). If symptoms resolve, contrast on an upper GI study passes to the small bowel, and liquids are tolerated, patients are discharged with planned interval repair. We sought to characterize the outcomes of this interval surgical strategy for incarcerated PEH. METHODS: A retrospective chart review was performed to identify patients admitted to a single institution between October 2019 and September 2023 with an incarcerated PEH. Patients taken directly to surgery within 24 h were excluded. RESULTS: A total of 45 patients admitted with obstruction from an incarcerated PEH were identified. Ten patients (22%) were taken urgently to surgery due to clinical instability and were excluded. Of the remaining 35 patients, 23 (66%) resolved their obstruction with conservative non-operative management and were offered planned interval PEH repair (successful conservative management). In the successful conservative management cohort, there was one unplanned readmission before interval PEH repair. Average time between discharge and repair was 25 days. Complication rates did not differ in those who failed and in those who had a successful conservative management result. The cumulative length of stay for those who succeeded in conservative management (including days for the interval surgery) was equivalent with those who underwent PEH repair during the index admission. CONCLUSION: A trial of conservative management in clinically stable patients with symptomatic incarcerated PEH appears to be safe and often avoids emergent repair without increasing perioperative complications or total days in the hospital.

Evaluation of clinico-radiological outcome of conservative treatment in patients with partial-thickness rotator cuff tears.

Objective: While some patients may require surgical treatment a lot of patients do recover on conservative treatment alone while the optimal treatment being unclear. The purpose of this study was to treat the PT-RCTs conservatively for a period of 6 months and to determine its clinical outcome, radiological outcome on MRI and the baseline clinical factors predictive of that outcome. Methodology: All patients with a partial tear of supraspinatus and/or infraspinatus on their 1st MRI and aged 18-80 years were eligible and 47 patients (22 males, 25 females) were enrolled. Patients were evaluated using a standardised format including clinical history, imaging, and ASES(American Shoulder and Elbow Surgeons) score. Patients underwent a course of physical therapy for a period of minimum of 6 months which was augmented with the use of analgesics and/or anti-inflammatory drugs, multivitamins and supplements which were patient specific. Patients were followed up at 3 months and 6 months, ASES score was calculated, and a follow-up MRI was done at 6 months to determine if their tear had healed, remained the same, or progressed. A patient that had a better ASES score at 6 months was tagged as "clinically improved". Radiologically, patients were considered treated "successfully" if the tear size was reduced or remained the same while some "failed" that had an increased size of tear. Result: Non-operatively treated patients demonstrated a mean ASES score of 63.45 ± 16.24 at the end of 6 months. Overall, 35 patients (74.5 %) had the same size, seven patients (14.9 %) demonstrated tear progression and 5 (10.6 %) patients showed a decrease in size of their tear on MRI done at 6 months. In the end, 30 (63.8 %) patients improved clinically and 40 (85.1 %) patients improved radiologically. Statistical analysis also showed that patients with their non-dominant side involved and with an atraumatic onset of their injury were more likely to improve clinically. Conclusion: Conservative treatment of PT-RCTs may lead to a successful clinical outcome but it may or may not reveal itself radiologically. ASES score is an effective tool to evaluate and manage various conditions of the shoulder and not just the rotator cuff. The baseline factors such as onset (traumatic versus atraumatic) and shoulder involved (dominant versus non-dominant) can predict the outcome of conservative treatment.

Comparative analysis of the degree of patient satisfaction after breast-conserving surgery with or without oncoplastic surgery: systematic review and meta-analysis.

Introduction: Conservative surgery is the gold standard for the treatment of single and small tumors and, combined with the concept of oncoplastic tumors, brings good aesthetic results while maintaining cancer safety. The objective was to comparatively analyze the degree of satisfaction of patients undergoing breast conserving surgery (BCS), with and without oncoplastic surgery (OPS) using level II OPS techniques. Methods: Review with a search in the databases MEDLINE (by PubMed), EMBASE, Clinical Trials, Scopus, Web of Science, BVS and Oppen gray. The meta-analysis of random effects was performed using the Der Simonian-Laird method considering the odds ratio (OR) with a 95% confidence interval (95% CI). Results: There was no statistically significant difference in the aesthetic outcome between women who underwent OPS and BCS (OR 0.90; 95% CI 0.62-1.30). The staging (OR 1.93; 95% CI 0.97-3.84; I 2 = 15.83%); tumor location [central (OR 1.28; 95% CI 0.06-27.49; I 2 = 17.63%); lower (OR 0.75; 95% CI 0.21-2.65; I 2 = 2.21%); superior (OR 0.67; 95% CI 0.26-1.74; I 2 = 0.00%] and tumor size (OR 8.73; 95% CI -11.82-29.28; I 2 = 93.18%) showed no association with the type of BCS performed, with or without OPS. The degree of satisfaction remains even in cases of extreme oncoplasty. Conclusion: The level of patient satisfaction in relation to BCS was similar to that of the group undergoing OPS, highlighting that OPS allows the patient's satisfaction rate to be maintained even in the case of large or multicentric tumors.

Four-Year Treatment Effect of Custom-Made Foot Orthosis on Pediatric Symptomatic Accessory Navicular Bone Combined with Flexible Flatfoot.

Purpose: Congenital accessory navicular bone (ANB) is a common variant in the foot and is prone to cause several clinical symptoms. Wearing custom-made foot orthosis is considered a desirable option; however, there is limited evidence of its effectiveness. This study aims to report the mid-term effect of foot orthosis for symptomatic pediatric ANBs. Methods: School-age children with symptomatic ANBs combined with flexible flatfoot in the authors' institute were recruited and got custom-made foot orthosis treatment. They were followed up over 4 years. The general characteristics of these children were collected before treatment, including age, gender, and body mass index (BMI). The indicators of foot symptoms, including frequency and location of pain, visual analogue scale (VAS), arch index (AI), and hind foot valgus angle (HVA), were measured during pretreatment and at the last follow-up. Results: Twenty-seven children were recruited for this study. After 4 years of custom-made foot orthosis treatment, significant improvements showed in pain frequency, VAS, AI, and HVA (P < 0.001). Type II ANBs showed a higher pain index pretreatment (P < 0.001) and reduced after treatment (P < 0.001). Conclusion: Mid-term effect of custom-made foot orthosis is inspiring in clinical symptoms of pediatric congenital ANBs combined with flexible flatfoot and may be an optional nonoperative treatment.

[Conservative treatment in orthopedic oncology surgery ?] / Traitement conservateur en chirurgie orthopédique oncologique ?

Bone tumors are and remain rare entities in our daily hospital clinical practice. Their appearance seems anecdotal but does not remain absent. They can manifest directly (pain, redness, functional impotence, suspicious mass, etc.) or indirectly (inflammatory or paraneoplastic syndrome, profuse sweating, emaciation, etc.). The most common benign bone tumors are non-ossifying bone fibroma. Then come osteochondroma and solitary bone cysts. For malignant tumors, osteosarcomas and chondrosarcomas are at the forefront. Primary bone lymphoma accounts for less than 1 % of these. In general, lymphomatous bone lesions are frequently metastasis from primary hematological lymphoma and are therefore treated by chemotherapy. An early surgical treatment of the bone tumor is most often not mandatory and a conservative therapy may represent a valuable option.

Les tumeurs osseuses sont et restent des entités rares dans notre pratique clinique hospitalière quotidienne. Leur apparition semble anecdotique, mais n'en demeure pas moins nulle. Elles peuvent se manifester de manière directe (douleur, rougeur, impotence fonctionnelle, masse suspecte…) ou indirecte (syndrome inflammatoire ou paranéoplasique, sudations profuses, émaciation…). Les tumeurs osseuses bénignes les plus fréquentes sont les fibromes osseux non ossifiants. Viennent ensuite les ostéochondromes et les kystes osseux solitaires. Concernant les tumeurs malignes, ce sont les ostéosarcomes et les chondrosarcomes qui sont en tête de file. Le lymphome osseux primitif ne représente que moins d'1 % de ces dernières. De manière générale, les lésions osseuses lymphomateuses retrouvées sont fréquemment des métastases provenant d'un lymphome hématologique primitif et se traitent donc par chimiothérapie. Le traitement chirurgical de la lésion osseuse ne s'impose généralement pas d'emblée et un traitement conservateur peut représenter la bonne marche à suivre.

Evaluation of the use of an antigravity device in leveling functional inequalities of the lower limbs and inhibiting the progression of idiopathic scoliosis.

BACKGROUND: The conservative treatment of idiopathic scoliosis (IS) may be enhanced through a combination of specialized physiotherapy, bracing, and the utilization of assistive devices. OBJECTIVES: This study aims to evaluate the efficacy of the GraviSpine device in supporting the conservative treatment of IS in children. MATERIAL AND METHODS: A cohort of 142 patients, aged 10-17 years with an average age of 12.76 ±1.75 years, undergoing treatment for IS with specific physiotherapy and bracing, received additional treatment with the GraviSpine device. The participants, selected based on inclusion and exclusion criteria, were divided into 2 age groups: group A (10-12 years) and group B (13-17 years). The mean follow-up period was 28.71 ±10.98 months. The assessment involved changes in post-treatment trunk rotation angles (ATR), Cobb angles, and functional lower limb length discrepancies (FLLDs) concerning age groups and scoliosis location. RESULTS: The proportion of patients showing improvement and stabilization was high in both groups A and B, at 71% and 90%, respectively. In group B, a significant reduction in the mean Cobb angle of -1.83° ±6.88°, p < 0.002, was observed. Furthermore, a significant decrease in the incidence of FLLDs was noted in thoracic and lumbar scoliosis locations, p < 0.002. CONCLUSIONS: To enhance the effectiveness of conservative treatment for IS, the utilization of an assistive device such as GraviSpine may be considered, particularly when the child presents functional inequality of the lower limbs.

Evaluation of the Management and Outcome of Patients with Retained Products of Conception after Gestational Week 23+0: A Retrospective Cohort Study.

Background: Retained products of conception after childbirth or miscarriage are associated with an increased rate of maternal complications, such as abnormal vaginal bleeding and infections. Late complications may also include intrauterine adhesions, causing infertility. Surgical interventions carry a certain risk. Thus, conservative management is often discussed as an alternative. The aim of this study was to assess the clinical outcomes of patients with retained products of conception, comparing a primary surgical approach to conservative management. Methods: We conducted a retrospective cohort study of 88 patients diagnosed with retained products of conception after 23+0 weeks of gestation at the Medical University Vienna between 2014 and 2022. Results: Forty-seven (53.4%) patients underwent primary surgical management and 41 (46.6%) primary conservative management. After primary conservative treatment, a complication could be observed in 10 (24.4%) women. In contrast, complications occurred in 32 (68.1%) women in the group with primary surgical treatment (p < 0.001). The most common complication in both groups was the ongoing suspicion of retained products of conception. Patients after primary surgical treatment were significantly more likely to require a secondary change in treatment (p < 0.001). Ultimately, secondary conservative management was applied in 30 (63.8%) patients. In contrast, only nine (21.95%) patients with primary conservative management required secondary surgical management. Conclusions: Due to the high risk of complications and persistent retained products of conception, primary surgical management should only be prioritized in hemodynamically instable or septic patients.
