Patients with multiple hereditary exostoses (MHE) frequently present a genu valgum deformity. Temporary hemiepiphysiodesis, such as hemiepiphyseal stapling, is relatively safe surgical method to correct angular deformities in skeletally immature patients, but its outcomes for deformity MHE patients have not been extensively reported. We investigated the of stapling (MHE group) and compared those idiopathic (idiopathic after adjusting potential bias.Data from 70 limbs (15 55 idiopathic),...
Under the hypothesis that elbow alignment, namely carrying angle, could predispose individuals to a specific type of pediatric fracture after fall onto an outstretched arm, we investigated relationship between radiographic angle and in children.Retrospective case-control study.Level I trauma center.We reviewed 374 children who were diagnosed with supracondylar (SCF, n = 208), lateral condylar (LCF, 132), radial neck (RNF, 34).The association was investigated.To adjust for bias, 2 statistical...
Background: The aim of the present study was to evaluate clinical value using lateral tibiocalcaneal (LTiC) angle, measured on a radiograph made with foot and ankle in maximal dorsiflexion, instead dorsiflexion (ADF) physical examination, as determining indicator need for percutaneous Achilles tenotomy after Ponseti serial cast treatment idiopathic clubfoot. Methods: We identified patients clubfoot who had been treated at our institution between March 2006 June 2012. After exclusion Diméglio...
Background A Korean version of Toronto Extremity Salvage Score (TESS), a widely used disease-specific patient-reported questionnaire for assessing physical function sarcoma patients, has not been developed. Objectives 1) to translate and cross-culturally adapt the TESS into Korean, 2) examine its comprehensibility, reliability validity. Methods was translated then back English, reviewed by committee develop consensus TESS. The administered 126 patients reliability, Results Comprehensibility...
Comorbidity has not been examined as an independent prognostic factor in soft tissue sarcoma (STS). We the impact of comorbidity on oncologic outcome STS with adjustment for possible confounding factors.A retrospective review was performed 349 patients who had undergone surgery high-grade localized extremity at our institute. Conditions known to alter risk mortality, defined Charlson index, were classified comorbidities and 43 (12%) least one time surgery. The association outcomes local...
A small proportion of children with Gartland type III supracondylar humeral fracture (SCHF) experience troubling limited or delayed recovery after operative treatment. We hypothesised that the level relative to isthmus humerus would affect outcome. retrospectively reviewed 230 who underwent closed reduction and percutaneous pinning (CRPP) for their SCHFs between March 2003 December 2012. There were 144 boys 86 girls, mean age six years (1.1 15.2). The clinico-radiological characteristics...
Background: Although international guidelines recommend bone screening for premenopausal breast cancer patients taking adjuvant tamoxifen, the effects of tamoxifen on osteoporosis and related risks remain controversial. The objective this study was to investigate incidence risk factors osteoporotic fractures in younger patients. Methods: A nationwide retrospective cohort conducted using South Korea Health Insurance Review Assessment Service claims data. rates fracture were calculated as...
Preoperative transcatheter arterial embolization for hypervascular bone tumors is now widely accepted as a safe and effective procedure reducing intraoperative blood loss surgical morbidity. However, few studies have reported the use of preoperative nonspine metastases from hepatocellular carcinoma. The goal this study was to assess effect on clinical outcomes in surgery metastasis Seventy-five patients with carcinoma pelvis extremities were reviewed retrospectively. population consisted 62...
The discoid lateral meniscus (DLM) in children often presents peripheral rim instability (PRI) and is susceptible to tear or subluxation, which manifests symptoms leads a poor prognosis. We aimed investigate the association between preoperative clinical MRI findings intraoperative of PRI.Children adolescents aged younger than 16 years who underwent surgical treatment for DLM were retrospectively reviewed. Cases bucket-handle not included because they would confound stability rim. Total 60...
We investigated the differential MRI findings in children with transient synovitis of hip whom septic arthritis was suspected. Under hypothesis that disease progression can alter representative findings, we stratified these accordance symptom duration as this correlate progression. analyzed 65 who underwent for acute pain and were suspected having a condition (i.e. presented fever or increased inflammatory markers) when imaging performed. Symptom defined interval from first presentation to...
Purpose We conducted a nationwide study to assess the incidence and treatment patterns of extremity soft tissue sarcoma (STS) in South Korea. Materials Methods The STS were assessed using two databases, Korea National Cancer Incidence (KNCI) database Health Insurance Review Assessment Service (HIRA) database. Results A total 1,236 patients newly diagnosed with during 3-year period, from 2009 2011. annual Korean population was approximately 0.9 per 100,000 people male bias that increased age...
Since 2015, we have performed arthroscopy-assisted closed reduction and percutaneous pinning (A/S-CRPP) for children with a displaced lateral condylar humeral fracture (LCF). The purpose of this study is to introduce our A/S-CRPP method present its outcomes.In total, 39 (>2 mm) LCFs which was initially attempted available follow-up data >12 months were retrospectively reviewed. in the following order: reduction, 1 provisional K-wire fixation, arthroscopic verification status, rereduction if...
Due to anatomical and biological similarities with humans, pigs are increasingly used for inflammation- immune-related studies in biomedical research, including the field of osteonecrosis osteoimmunology. Here, we present a protocol rib extraction, isolation bone marrow by centrifugation, processing obtain bone-marrow-derived macrophages (BMDMs). Then, describe procedures vitro experiments evaluate cell phenotype. For complete details on use execution this protocol, please refer Andre et al.1
Background: Calcaneal lengthening osteotomy (CLO) is one of the main surgical options for treatment pediatric idiopathic flexible flatfoot (FFF). Reportedly, calcaneocuboid (CC) joint subluxation occurs after CLO; however, its effect on midfoot remains unclear. This study aimed to investigate radiologic midterm results CLO in FFF. Methods: We evaluated 23 patients with FFF aged ≥8 years, who underwent from 1999 2017 owing moderate severe deformity (assessed by visual inspection). Patients...
The presence of asymmetric skin folds in the medial thigh (ASM) is often used as one screening items for developmental dysplasia hip (DDH). However, few studies have evaluated clinical relevance ASM DDH.We reviewed data 584 infants aged 4-12 months who were referred to our institute because suspicious findings periodic infantile DDH screenings. reasons referral classified into ASM, gluteal asymmetry, limb-length discrepancy, limitation abduction, and click/clunk hip. A simple radiograph...
