Validity and reliability of the adapted Dutch version of the Brace Questionnaire (BrQ).

Background And Purpose: The Brace Questionnaire (BrQ) is a disease-specific health-related quality of life (HRQOL) instrument for measuring perceived health status of scoliosis patients undergoing brace treatment. The purpose of this study is to evaluate the validity and reliability of a translated and culturally adapted Dutch version of the BrQ.

Patients And Methods: The original Greek BrQ was translated into Dutch and a cross-cultural adaptation and validation processes were conducted.

A Prospective, Randomized, Multicenter Study Comparing Silicated Calcium Phosphate versus BMP-2 Synthetic Bone Graft in Posterolateral Instrumented Lumbar Fusion for Degenerative Spinal Disorders.

Study Design: A prospective, Phase IV, multicenter, randomized study.

Objective: The aim of this study was to compare vertebral fusion success rates following posterolateral fusion [(PLF)/posterolateral intertransverse fusion (PITF)] surgery. The surgical procedure combined posterior lumbar interbody fusion (PLIF) and PLF with internal fixation over one or two levels using silicated calcium phosphate (SiCaP) or bone morphogenetic protein (BMP)-2 as graft material in patients with a degenerative disorder of the lumbar spine.

Scoliosis surgery in a patient with "de novo" myosin storage myopathy.

Myosin storage myopathy is a rare neuromuscular disorder, characterized by subsarcolemmal inclusions exclusively in type I skeletal muscle fibers, known as hyaline bodies. Its clinical spectrum is diverse, as are its modes of inheritance. Myosin storage myopathy, also called hyaline body myopathy, is caused by a pathogenic mutation in the MYH7 gene, encoding for the slow/β-cardiac myosin heavy chain.

[Mazabraud syndrome--benign intramuscular myxoma with fibrous skeletal dysplasia].

A 51-year-old woman presented with a soft-tissue swelling of the thigh. A MRI scan of the thigh showed an intramuscular lesion and bone-marrow abnormalities in the femur. A bone scintigraphy and PET/CT-scan showed multiple hotspots in the skeleton.

Esophageal rupture in a child after vertical expandable prosthetic titanium rib expansion thoracoplasty: first report of a rare complication.

Study Design: Case report and clinical discussion.

Objective: To illustrate the significance of esophageal rupture as a rare complication after expansion thoracoplasty with implementation of a vertical expandable prosthetic titanium rib (VEPTR).

Summary Of Background Data: Chest wall deformities and secondary scoliosis are rare complications after a repair operation for esophageal atresia.

Congenital convex pes valgus (congenital vertical talus). The condition and its treatment: a review of the literature.

Much discussion exists about the best operative technique to treat congenital convex pes valgus. In this article a table of surgical approaches and an algorithm, based upon literature review, are presented. In our opinion the technique of choice in a child younger than 2 years of age is extensive release with lengthening of tendons and fixation procedures.

The natural history of developmental dysplasia of the hip: sonographic findings in infants of 1-3 months of age.

The natural history of sonographic developmental dysplasia of the hip was determined in a population-based study in which 5170 infants were screened by ultrasound using Graf's method. Of the normal hips at the age of 1 month, 99.6% were still normal at the age of 3 months.
