Introduction The best treatment option in children with late detected DDH is still a subject of much controversy and only few studies have investigated the long-term outcome of treatment in such patients. We performed a systematic review to assess long-term outcome of late detected DDH hips treated after walking age. Methods Studies met...

Objectives: To assess the treatment and outcomes of supracondylar humeral fractures (SHFs) in children older than 10 years of age at the time of injury. Methods: The study analyzed clinical data from 60 patients who sustained SHF, all over the age of 10 years, were analyzed. The patients included 49 males and 11 females with a mean age of 10.9...

Some patients with developmental dysplasia of the hip (DDH) before 6 months of age successfully treated by Pavlik Harness (PH) still had persistent acetabular dysplasia (PAD), and the factors leading to PAD following PH treatment are still controversial. This study aimed to investigate the incidence and risk factors for PAD in patients with DDH...

Background Closed reduction and spica cast is still the preferred treatment option for children presenting with developmental dysplasia of the hip (DDH) after the age of 6 months. This study aims to investigate the outcomes of patients with DDH treated by closed reduction and dynamic cast immobilization. Methods In total, 159 patients (mean age...

Purpose: The purpose of this study was to identify the correlation between the vascular development of the femoral head and avascular necrosis (AVN) in patients with developmental dysplasia of the hip (DDH) treated by closed reduction (CR). Methods: We retrospectively reviewed 78 patients with DDH treated by CR (83 hips). The vascular maturity,...

Purpose The objectives of this study were to (1) evaluate the radiographic characteristics of children with congenital thumb duplication (CTD) seen in our institution between August 2015 and April 2021; (2) introduce a modified radiographic classification system (MCS) capable of including all cases of CTD based on their radiographic...

a b s t r a c t Background: Open reduction with or without pelvic and femoral osteotomy is the accepted treatment option for children older than 18 months with developmental dislocation of the hip (DDH). However, few studies have investigated hip function in children with late DDH treated by open reduction. Therefore, we performed a...

Objective: The objective of this study was to evaluate epidemiological and anatomical characteristics of children with congenital thumb duplication (CTD). Methods: We retrospectively reviewed 2108 children with CTD. Data regarding sex, age at the surgery, laterality, uni- or bilateral involvement, and dominant side were retrieved from the...

Abstract Purpose The purpose of this study was to introduce a new classification system for pediatric femoral neck fractures (PFNFs) and to evaluate its reliability. Methods Two hundred and eight unilateral PFNFs (mean patient age: 9.0 ± 4.8 years) were included. Based on preoperative radiographs, the new classification system distinguished...

Background: In patients with untreated scoliosis or in those with posterior spinal instrumented fusion (PSF), the movements of neither the thoracic cage (ThC) nor the abdomen (ABD) during quiet and deep breathing have been well defined in the literature. The purpose of this study was to evaluate kinematic variations in the ThC and ABD during...

Background: The incidence of aggravation or occurrence of avascular necrosis (AVN) following hardware removal in surgically treated pediatric femoral neck fractures who achieved radiologic consolidation is unknown. This study aimed to investigate the risk factors for this complication. Methods: Seventy-one pediatric (mean age: 9.8± 3.9 y)...

To evaluate demographic characteristics and distribution of pediatric supracondylar fractures (SCFs) at a tertiary hospital in South China. A retrospective observational study was conducted on children aged 15 years or younger with a diagnosis of SCFs during the period from January 2016 to December 2018. Patients' medical records and...

Trunk movements during quiet and deep breathing in untreated and in operated patients with scoliosis are not well defined. To evaluate sagittal and transverse plane cross-sectional variations of the trunk during quiet and deep breathing by optical reflective motion analysis (ORMA) in children with scoliosis. Twenty-one patients were divided...

Abstract Purpose: This study aims to evaluate (1) the probability to achieve normal pelvic radiographs in children with developmental dysplasia of the hip (DDH) treated by closed reduction and (2) the amount of time needed to achieve normal pelvic radiographs and to assess what factors influence both probability and time to achieve normal...

Abstract Background: The difference between MRI (Magnetic resonance imaging)-R2* and T2 mapping sequences regarding their superiority in the detection of microstructural cartilage changes in knees with limited ROM (range of motion) was unknown. Methods: Twenty male cynomolgus monkeys (mean age: 10.65 ± 0.97 years) underwent knee ROM evaluations...

Purpose This study aimed to investigate the radiographic outcomes, rate of redislocation, and avascular necrosis of proximal femoral epiphysis (AVN) in patients aged 24 to 36 months with developmental dysplasia of the hip (DDH) treated by closed reduction (CR) and spica cast immobilization in human position. Material and methods We reviewed the...

Purpose To compare the outcomes of type II pediatric phalangeal neck fractures (PPNFs) treated with closed reduction and cast immobilization (CRCI) versus closed reduction percutaneous pinning (CRPP), and evaluated the clinical efficacy of conservative versus surgical treatment of type II PPNFs via meta-analysis. Methods Patients aged ≤ 14...
