Correlation between the Oswestry Disability Index and objective measurements of walking capacity and performance in patients with lumbar spinal stenosis: a systematic literature review.

Purpose: The Oswestry Disability Index (ODI) plays a significant role in lumbar spinal stenosis research and is used to assess patient's walking limitations. The World Health Organisation describes the constructs of walking capacity and performance and recommend measuring both to fully describe patient's walking ability. Objective methods to assess walking capacity and performance is being investigated and used alongside the traditional use of PROs.

National Clinical Guidelines for non-surgical treatment of patients with recent onset low back pain or lumbar radiculopathy.

Purpose: To summarise recommendations about 20 non-surgical interventions for recent onset (<12 weeks) non-specific low back pain (LBP) and lumbar radiculopathy (LR) based on two guidelines from the Danish Health Authority.

Methods: Two multidisciplinary working groups formulated recommendations based on the GRADE approach.

Results: Sixteen recommendations were based on evidence, and four on consensus.

The Role of Body Weight on Bone in Anorexia Nervosa: A HR-pQCT Study.

Anorexia nervosa (AN) is associated with decreased bone mineral density and increased risk of fracture. The aim of this study was to assess bone geometry, volumetric bone mineral density (vBMD), trabecular microarchitecture and estimated failure load in weight-bearing vs. non-weight-bearing bones in AN.

Mutation of the Planar Cell Polarity Gene VANGL1 in Adolescent Idiopathic Scoliosis.

Study Design: Mutation analysis of a candidate disease gene in a cohort of patients with moderate to severe Adolescent idiopathic scoliosis (AIS).

Objective: To investigate if damaging mutations in the planar cell polarity gene VANGL1 could be identified in AIS patients.

Summary Of Background Data: AIS is a spinal deformity which occurs in 1% to 3% of the population.

Incidence of cancer in adolescent idiopathic scoliosis patients treated 25 years previously.

Purpose: To report the incidence of cancer in a cohort of adolescent idiopathic scoliosis (AIS) patients treated 25 years previously.

Methods: 215 consecutive AIS patients treated between 1983 and 1990 were identified and requested to return for clinical and radiographic examination. The incidence of cancer was determined through chart review and follow-up interviews.

Concordance Rates of Adolescent Idiopathic Scoliosis in a Danish Twin Population.

Study Design: Clinical, radiological, and genetic determination of zygosity of twin pairs from the Danish Twin Registry who self-reported having adolescent idiopathic scoliosis (AIS).

Objective: To establish concordance rates of AIS.

Summary Of Background Data: The etiology of and the true mode of inheritance of AIS remain unclear.

Rate of Unsuspected Malignancy in Patients With Vertebral Compression Fracture Undergoing Percutaneous Vertebroplasty.

Study Design: Retrospective study.

Objective: To determine the malignancy rate and histology in bone biopsies obtained during PVP for VCF.

Summary Of Background Data: Osteoporotic vertebral compression fractures (VCF) affect approximately 20% of postmenopausal women and can lead to long-term disability.

Patient-reported outcome measures unbiased by loss of follow-up. Single-center study based on DaneSpine, the Danish spine surgery registry.

Purpose: The purpose of this study is to determine if there are any demographic and reporting differences between patients who respond and those who refuse to respond to postal questionnaires from the Danish national spine database, DaneSpine.

Methods: DaneSpine collects patient-reported data, completed before surgery and at 3 months, and at 1, 2, 5, and 10 years postoperatively. The database was launched at the Center for Spine Surgery and Research at Lillebaelt Hospital on June 1st, 2010.
