Comparison of cone beam computed tomography and plane radiographs of radial fractures as a basis for radiographical measurements.

Background: The purpose of this study was to determine whether radiological measurements of radial fracture position made in cone beam computed tomography (CBCT) projection images are comparable to those made on traditional radiographs and could potentially substitute them.

Methods: Sixteen patients with fractures of the distal radius referred for radiographs were recruited for an additional CBCT scan which was performed immediately afterwards. Projection images and volumetric data were saved from the CBCT scans.

Reliability of T2-weighted signal intensity-based quantitative measurements and visual grading of lumbar disc degeneration on MRI.

Background: Decrease in signal intensity (SI) of the nucleus pulposus (NP) on T2-weighted (T2W) images, a sign of disc degeneration (DD), is usually graded based on an observer's image interpretation. No gold standard for quantitative assessment of NP SI exists to date.

Purpose: To compare different quantitative methods and visual gradings of lumbar DD and to evaluate the ability of the quantitative methods to differentiate DD grades.

Disc Degeneration of Young Low Back Pain Patients: A Prospective 30-year Follow-up MRI Study.

Study Design: A prospective follow-up study.

Objective: The aim of this study was to investigate whether early lumbar disc degeneration (DD) in young low back pain (LBP) patients predicts progression of degenerative changes, pain, or disability in a 30-year follow-up.

Summary Of Background Data: MRI is an accurate method for studying degenerative changes in intervertebral discs.

Letrozole Monotherapy in Pre- and Early-Pubertal Boys Does Not Increase Adult Height.

Aromatase inhibitors (AIs) have been used in boys with idiopathic short stature (ISS) to promote growth despite the lack of actual data regarding treatment effect on adult height. In this study, we characterized adult heights and long-term follow-up in AI-treated boys with ISS. Adult heights and long-term follow-up data, including spine MRIs, of a randomized, double-blind, placebo-controlled trial of boys who were treated with letrozole (Lz) (2.

Cross-sectional area of the paraspinal muscles and its association with muscle strength among fighter pilots: a 5-year follow-up.

Background: A small cross sectional area (CSA) of the paraspinal muscles may be related to low back pain among military aviators but previous studies have mainly concentrated on spinal disc degeneration. Therefore, the primary aim of the study was to investigate the changes in muscle CSA and composition of the psoas and paraspinal muscles during a 5-year follow up among Finnish Air Force (FINAF) fighter pilots.

Methods: Study population consisted of 26 volunteered FINAF male fighter pilots (age: 20.

Chronic low back pain in relation to Modic changes, bony endplate lesions, and disc degeneration in a prospective MRI study.

Purpose: To clarify the significance of Modic changes, bony endplate lesions, and disc degeneration as predictors of chronic low back pain (LBP) during 1-year follow-up.

Methods: 49 patients with severe, non-specific, chronic LBP, and Modic 1 lesion (M1) were prospectively studied with MRI and questionnaire. Changes in grade of disc degeneration, severity of Modic changes, Schmorl lesions, and bony endplate irregularities were evaluated and changes assessed in LBP intensity on numeric rating scale 0-10 and severity with Oswestry disability index 0-100 (ODI).

Modic type I change may predict rapid progressive, deforming disc degeneration: a prospective 1-year follow-up study.

Introduction: This prospective magnetic resonance imaging (MRI) study in chronic low-back pain (CLBP) patients evaluated the natural course of degenerative lumbar spine changes in relation to Modic 1 type changes (M1) within 1 year.

Materials And Methods: From 3,811 consecutive CLBP patients referred to lumbar spine MRI 54 patients with a large M1 were selected using strict exclusion criteria to exclude specific back disorders. Follow-up MRI was obtained within 11-18 months.

Prevalence of vertebral compression fractures and associated factors in children and adolescents with severe juvenile idiopathic arthritis.

Objective: Vertebral fractures occur in patients with juvenile idiopathic arthritis (JIA), but data on their frequency and causes are scarce. Our cross-sectional study evaluated prevalence of compression fractures and associated factors in a high-risk pediatric population with severe JIA.

Methods: Children and adolescents with a history of treatment-resistant polyarticular-course JIA for ≥ 5 years or systemic arthritis for ≥ 3 years were recruited.

The thoracic and lumbar spine in severe juvenile idiopathic arthritis: magnetic resonance imaging analysis in 50 children.

Objective: To determine the prevalence of vertebral fractures as a complication of juvenile idiopathic arthritis (JIA).

Study Design: This cross-sectional study evaluated the prevalence and characteristics of spinal abnormalities in 50 children (aged 7.0-18.

Correlation of size and type of modic types 1 and 2 lesions with clinical symptoms: a descriptive study in a subgroup of patients with chronic low back pain on the basis of a university hospital patient sample.

Study Design: Intensity of pain and level of disability (Oswestry Disability Index [ODI]) were compared with the relative size of Modic type 1 (M1) and Modic type 2 (M2) lesions. Clinical symptoms of patients having mixed M1-M2 lesion (n = 49) were compared with patients having a "pure" M1 lesion (n = 13).

Objective: To determine the relation of the sizes of M1 and M2 lesions and the type of Modic lesion (mixed M1-M2 or pure M1 lesion) with intensity of low back pain and level of perceived disability.

Relationship of Modic type 1 change with disc degeneration: a prospective MRI study.

Objective: The objective was to study the natural course of Modic type 1 change (M1) in relation to lumbar disc degeneration.

Materials And Methods: Twenty-four chronic low back pain (LBP) patients with M1 on lumbar spine were selected from 1,015 patients with magnetic resonance imaging from a follow-up study lasting for 18-74 months. Exclusion criteria were any other specific back disorder, age >or=60 years, or a recent spine operation.

MRI follow-up of subchondral signal abnormalities in a selected group of chronic low back pain patients.

Subchondral signal abnormalities have been suggested to play an important role in chronic low back pain (LBP) syndromes. Their natural course is not well known. In this study the morphology and natural course of isolated subchondral signal abnormalities in the lumbosacral spine were analyzed with MRI.

Ankle osteoarthritis is associated with knee osteoarthritis. Conclusions based on mechanical axis radiographs.

Introduction: Osteoarthritis (OA) of the ankle with an unknown etiology (primary OA) is rare, whereas a secondary OA due to a known cause is not uncommon. OA of the knee can, when it progresses, change the alignment of the whole extremity including the ankle joint. Since we had observed in patients coming for OA knee surgery coexisting OA in the ankle joint, our objective of this study was to assess the prevalence of abnormal alignment and degenerative changes in the ankle joint and to determine if degenerative changes in the knee and ankle correlated.
