There is no consensus on how to predict residual equinovarus deformities after application of the Ponseti method. We assessed prognostic value clinical scoring systems, and also radiographic parameters that can be measured just before percutaneous Achilles tenotomy (PAT).We reviewed 50 cases clubfoot in 35 patients who were treated using method, including PAT, analyze factors are predictive deformities. Mean age at time PAT was 2.4 (1.4-3.5) months, mean follow-up period 23 (9-61) months....
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...
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 radiographic changes of calcaneocuboid (CC) joint subluxation following calcaneal lengthening procedure for the treatment pediatric planovalgus foot deformities.This study included 44 cases deformities in 24 patients with mean age 9.7 (range, 8 to 13) years who underwent between 1999 and 2011. The follow-up period was 25 12 159) months. Anteroposterior (AP) lateral radiographs weight-bearing view from immediate postoperative, 3-month last evaluations were reviewed also used...
Regardless of the mode treatment, clubfoot has a strong tendency to relapse, especially hindfoot equinus. Because contraction or shortening Achilles tendon causes an equinus deformity ankle, release this is required correct in patients with residual relapsed clubfoot. This study assessed effectiveness Vulpius technique correcting clubfoot.Of 80 idiopathic clubfeet treated conservatively using Ponseti protocol, between March 2000 and July 2008, 32 were found have deformity, 22 feet 17...
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...
To investigate the fracture pattern and periosteal entrapment in adolescent distal tibial physeal fractures.Retrospective case series.Level I academic trauma center.Fifty patients (10-16 years of age) with displaced Salter-Harris type II, III, or IV fractures were retrospectively reviewed.Periosteal involvement, pattern.We investigated incidence location those angle plane metaphyseal fragments on axial by using magnetic resonance imaging.Of 15 12 III (4 malleolar 8 Tillaux), 23 (2 21...
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...
Various methods based on bony landmarks are used to determine patellar height. This study analyzed five for height measurement lateral knee radiographs, namely, the Insall-Salvati, Koshino-Sugimoto, Blackburne-Peel, modified and Caton-Deschamps methods.Overall, 425 pediatric participants (221 males, 204 females; age range 5-18 years) were included divided equally into three groups (A, 5-10 years; B, 11-13 C, 13-18 years). For comparison of applicability each method, applicable probabilities...
Introduction Various measurement methods and imaging technique are in use to measure patellar height pediatric patients. However, there is no gold standard as which method modality the most reliable for Therefore, aim of this study was determine inter-observer reliability, intra-observer applicability various knee. Additionaly, we analyzed reliability across different modalities. Methods Total 450 patients (age: 5–18 years) were evaluated using lateral knee radiographs magnetic resonance...
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...
Ogden type IV tibial tuberosity fractures, defined as a of fracture with posterior-inferior metaphyseal extension (Salter-Harris II variant), are uncommon but challenging pediatric fractures. The purpose this study was to investigate the clinical and radiological presentation associated surgical outcomes.Ten previously healthy patients who had been surgically treated at authors' institution between 2015 2018 least 2 years postoperative follow-up were included. Demographic, clinical,...
Introduction Caudal epidural block is a commonly used analgesic technique in pediatric patients. Ultrasound could be to increase the accuracy of by visual confirmation drug-spreading. Therefore, we aimed estimate cephalad spread injection volume caudal route using dynamic ultrasound imaging young Methods Forty patients, aged 6–24 months, undergoing foot surgery were included. After inducing general anesthesia, an angiocatheter was inserted into sacral canal under guidance. Thereafter, probe...
Background Many case studies have been published about trampoline-related injury (TRI); however, a comparative study could allow more specific analysis of the characteristics TRI, and enable differentiated approaches to prevent such injuries. We investigated mechanism TRI in children compared with other pediatric trauma. Methods Of 35,653 (age 0–18 years) who visited emergency department after traumatic injuries from January 2011 June 2017, 372 patients (TRI group) were retrospectively...
Many studies have reported injury characteristics of individual traumatic situations. However, a comparative analysis specific risks is meaningful to better understand and help establish injury-prevention measures. This study was conducted investigate compare in children adolescents by various outdoor situations.Outdoor situations were determined classified into physical activity-related (n = 3,983) pedestrian 784) passenger 1,757) injuries traffic accidents. Home 16,121) used as the control...

This study aimed to investigate the clinico-radiological factors of related future surgical treatment in patients with pediatric flexible flatfoot (FFF) who first visited orthopedic clinic before age 10 years. Sixty-five diagnosed moderate/severe idiopathic FFF deformity between ages 2–10 years were included. We developed prognostic models for risk surgery during follow-up period. Twenty (30.8%) required treatment, and all them underwent calcaneal lengthening osteotomy. Among them, 7 (10.8%)...
Selective soft tissue release (SSTR), which includes a combination of abductor hallucis, tibialis posterior, and Achilles lengthening, has been used in patients with recurrent clubfoot deformity after Ponseti treatment. The aim this study was to investigate the prognostic factors for recurrence SSTR.Consecutive idiopathic residual or treatment underwent SSTR between 2005 2013. clinical radiologic characteristics before were analyzed. ability predict assessed using multivariate analysis....
