BACKGROUND Scoliosis is a common spinal deformity that occurs often during adolescence. Previous studies suggested that adolescent idiopathic scoliosis (AIS) patients can have various aspects of their lives being affected, due to disease presentation and/or treatment received. It is important to define a reliable instrument based on which the affected(More)
AIMS We report the use of the distal radius and ulna (DRU) classification for the prediction of peak growth (PG) and growth cessation (GC) in 777 patients with idiopathic scoliosis. We compare this classification with other commonly used parameters of maturity. PATIENTS AND METHODS The following data were extracted from the patients' records and(More)
INTRODUCTION Twin studies are a most effective method to analyse gene and environment interactions. Using data from the Singapore National Registry of Births and Deaths (SNRBD), this paper describes the number of twin and multiple births among different ethnic populations in Singapore. MATERIALS AND METHODS All births recorded in the SNRBD from 1 January(More)
Study Design Prospective radiographic study. Objective To test the reliability of the Distal Radius and Ulna Classification (DRU). Methods This single-center study included prospectively recruited subjects with adolescent idiopathic scoliosis managed with bracing. The left-hand radiographs were measured using the DRU classification by two examiners. Intra-(More)
The aim of this study is to simplify the distal radius and ulna classification for practical use and to test its reliability. This was a prospective single-center study of patients with juvenile and adolescent idiopathic scoliosis. Left-hand radiographs were retrieved for measurements by three examiners. Reliability analysis was carried out by intraclass(More)
STUDY DESIGN Retrospective series. PURPOSE Assess results of decompression-only surgery for low-grade degenerative spondylolisthesis with consideration of instability. OVERVIEW OF LITERATURE There is no consensus on whether fusion or decompression-only surgery leads to better outcomes for patients with low-grade degenerative spondylolisthesis. Current(More)
PURPOSE To compare the yearly cost involved per patient in the use of magnetically controlled growing rod (MCGR) and traditional growing rods (TGRs) in the treatment of early onset scoliosis (EOS) and to assess the overall cost burden of MCGR with reference to patient and health-care infrastructure. METHODS For a hypothetical case of a 5-year-old girl(More)
Traditional medical therapies for scoliosis are mostly based on the experience and intuitions of doctors, which does not guarantee the effectiveness of the treatment. Scoliosis prediction is of great significance to reduce the uncertainty for doctors on deciding the optimum treatment for patients. The paper aims to develop a prediction model to help(More)
BACKGROUND Patients with developmental spinal stenosis (DSS) are susceptible to developing symptomatic stenosis due to pre-existing narrowed spinal canals. DSS has been previously defined by MRI via the axial anteroposterior (AP) bony spinal canal diameter. However, MRI is hardly a cost-efficient tool for screening patients. X-rays are superior due to its(More)
To test the responsiveness of the EuroQoL 5-dimension (EQ-5D) utility scores for adolescent idiopathic scoliosis (AIS). A baseline sample of 227 AIS patients was recruited between August and October 2015, and was surveyed prospectively to 9–12 months follow-up. EQ-5D-5L utility scores were derived using a two-step approach: (1) cross-walking from five-level(More)
