Feasibility and usefulness of video-based markerless two-dimensional automated gait analysis, in providing objective quantification of gait and complementing the evaluation of gait in children with cerebral palsy.

Background: Gait analysis aids in evaluation, classification, and follow-up of gait pattern over time in children with cerebral palsy (CP). The analysis of sagittal plane joint kinematics is of special interest to assess flexed knee gait and ankle joint deviations that commonly progress with age and indicate deterioration of gait. Although most children with CP are ambulatory, no objective quantification of gait is currently included in any of the known international follow-up programs.

Distal radius fractures in children aged 5-12 years: a Swedish nationwide register-based study of 25 777 patients.

Background: Distal radius fracture (DRF) is the most common type of fracture in children. There is no clear consensus on primary treatment for complete DRFs. Kirschner wire (K-wire) fixation has been recommended, to avoid the risk of redislocation.

Patient-reported Outcome After Surgical Evacuation of Postoperative Spinal Epidural Hematomas at One-year Follow-up.

Study Design: Retrospective analysis of prospectively collected data from the National Swedish Spine Register (Swespine).

Objective: The objective of this study was to evaluate the effects of symptomatic spinal epidural hematoma (SSEH) requiring reoperation on one-year patient-reported outcome measures (PROMs) in a large cohort of patients treated surgically for lumbar spinal stenosis.

Summary Of Background Data: Studies exploring the outcomes of reoperations after SSEH are scarce and often lack validated outcome measures.

Additional operation rates after surgery for degenerative spine diseases: minimum 10 years follow-up of 4705 patients in the national Swedish spine register.

Objectives: To identify rates of additional operation after the index operation for degenerative lumbar spine diseases.

Design: Retrospective register study.

Setting: National outcome data from Swespine, the National Swedish spine register.

Handling of missing items in the Oswestry disability index and the neck disability index. A study from Swespine, the National Swedish spine register.

Purpose: The Oswestry Disability Index (ODI) and the Neck Disability Index (NDI) scoring algorithms used by the Swedish spine register (Swespine) until April 2022 handled missing items somewhat differently than the original algorithms. The purpose of the current study was to evaluate possible differences in the ODI and NDI scores between the Swespine and the original scoring algorithms.

Methods: Patients surgically treated for degenerative conditions of the lumbar or cervical spine between 2003-2019 (lumbar) and 2006-2019 (cervical) were identified in Swespine.

The minimal important change for the EQ VAS based on the SF-36 health transition item: observations from 25772 spine surgery procedures.

Purpose: The EQ VAS is an integral part of EQ-5D, a commonly used instrument for health-related quality of life assessment. This study aimed to calculate the minimal important change (MIC) thresholds for the EQ VAS for improvement and deterioration after surgery for disk herniation or spinal stenosis.

Methods: Patients, who were surgically treated for disk herniation or spinal stenosis between 2007 and 2016, were recruited from the Swedish spine register.

Single item self-rated general health: SF-36 based observations from 16,910 spine surgery procedures.

Purpose: In spine surgery single item patient-reported outcome assessment has been used for many years. Items 1 and 2 of SF-36 are used for assessment of general health. We used these items to explore single item, self-rated, general health assessment after spine surgery.

Patients with no preoperative back pain have the best outcome after lumbar disc herniation surgery.

Purpose: Most patients with lumbar disc herniations requiring surgery have concomitant back pain. The purpose of the current study was to evaluate the outcome of surgery for lumbar disc herniations in patients with no preoperative back pain (NBP) compared to those reporting low back pain (LBP).

Methods: 15,418 patients surgically treated due to LDH with primary discectomy from 1998 until 2020 were included in the study.

Responsiveness of the SF-36 general health domain: observations from 14883 spine surgery procedures.

Purpose: The study evaluated perceptions of general health (GH) after surgical treatment of spinal stenosis and disk herniation. We used a large longitudinally collected data set to explore differences in responsiveness between the SF-36 GH domain, EQ VAS, EQ-5D index, and SF-6D index.

Methods: Patients, surgically treated for lumbar spinal stenosis or lumbar disk herniation between 2007 and 2017, were recruited from the national Swedish spine register.

Properties of SF-6D when longitudinal data from 16,398 spine surgery procedures is applied to 9 national SF-6D value sets.

Background and purpose - There are several national value sets for SF-6D. For studies conducted in countries without a country-specific value set the authors may use a value set from a neighboring or culturally similar county. We evaluated the consequences of using different national value sets in SF-6D index-based outcome analyses.

Reoperations after decompression with or without fusion for L4-5 spinal stenosis with or without degenerative spondylolisthesis: a study of 6,532 patients in Swespine, the national Swedish spine register.

Background and purpose - There are different opinions on how to surgically address lumbar spinal stenosis with concomitant degenerative spondylolisthesis (DS). We investigated reoperation rates at the index and adjacent levels after L4-5 fusion surgery in a large cohort of unselected patients registered in Swespine, the national Swedish spine register.Patients and methods - 6,532 patients, who underwent surgery for L4-5 spinal stenosis with or without DS between 2007 and 2012, were followed up to 2017 to identify reoperations at the index and adjacent levels.

Properties of the EQ-5D-3L index distribution when longitudinal data from 27,328 spine surgery procedures are applied to nine national EQ-5D-3L value sets.

Purpose: The purpose of the current study was to apply a single large longitudinal EQ-5D-3L data set to several national EQ-5D-3L value sets and explore differences in EQ-5D-3L index density functions and effect sizes before and after treatment.

Methods: Patients, surgically treated for lumbar spinal stenosis or lumbar disk herniation between 2007 and 2017, were recruited from the national Swedish spine register. A total of 27,328 procedures were eligible for analysis.

Self-Image and Health-Related Quality of Life Three Decades After Fusion In Situ for High-Grade Isthmic Spondylolisthesis.

Study Design: Observational study.

Objectives: To evaluate self-image after in situ fusion for high-grade isthmic spondylolisthesis.

Summary Of Background Data: Certain clinical findings such as short trunk or waistline skin folds are often seen in high-grade spondylolisthesis.
