ABSTRACT

BACKGROUND CONTEXT: Whiplash-associated disorder is a common cause of chronic neck pain. Several radiological cervical angular variables are suggested to have constitutional characteristics, that is, them being minimally influenced by body positioning. However, the association between these variables and pain conditions remains poorly understood. To our knowledge, no previous studies have investigated the association between constitutional angular variables and the outcome after whiplash trauma. PURPOSE: Our objectives were (1) to study the inter-rater agreement of sagittal radiologic variables between 2 raters and (2) to investigate any association between these variables and self-perceived nonrecovery after whiplash injury. STUDY DESIGN: Prospective cohort study. PATIENT SAMPLE: Forty-six patients aged 16 to 70 years, attending an emergency department after a motor vehicle accident resulting in neck pain were recruited. OUTCOME MEASURES: Self-perceived nonrecovery (yes/no) was the primary outcome measure. The secondary outcome measure was pain level on a numeric rating scale. METHODS: The participants underwent computed tomography scans in a supine position. Sagittal alignment variables (T1 slope, neck tilt, thoracic inlet angle [TIA], and C2-C7 angle) on the computed tomography scans were measured by 2 independent raters. Inter-rater agreement was tested with a paired sample t test and Bland-Altman plots for each variable. The patients were followed up after 6 months. RESULTS: No systematic differences for the assessed variables were found between the 2 raters. The overall nonrecovery rate was 28%. For the group with low neck tilt, the nonrecovery rate was 50% (95% CI: 36%-78%) and for the group with high neck tilt, 8% (95% CI: 3%-25%). The nonrecovery rate for the group low TIA was 50% (95% CI 29%-72%) and for those with high TIA 14% (95% CI 4%-26%). The associations remained significant after adjustments for possible confounders. The inter-rater analysis shows satisfactory agreement without proportional bias. CONCLUSIONS: This study indicates the existence of an association between the constitutional sagittal alignment of the cervical spine and the outcome after whiplash injuries.

ABSTRACT

BACKGROUND CONTEXT: Disc-related sciatica has a prevalence of about 2% in adults, but is rare in adolescents. If conservative treatment is unsuccessful, surgery is an option. PURPOSE: The aim of this study was to compare the outcomes of surgery for lumbar disc herniation in adolescents with adults in the Swedish Spine Register. STUDY DESIGN/SETTING: This is a prospective observational study: National Quality Register. PATIENT SAMPLE: This study included 151 patients, 18 years or younger, 4,386 patients, 19-39 years, and 6,078 patients, 40 years or older, followed for 1-2 years after surgery. OUTCOME MEASURES: The primary outcomes were patient satisfaction and global assessment of leg and back pain. Secondary outcomes were Visual Analog Scale (VAS) leg pain, VAS back pain, Oswestry disability index (ODI), and EuroQol-5 dimensions (EQ-5D). METHODS: Statistical analyses were performed with the Welch F test, the chi-square test, and the Wilcoxon signed-rank test. RESULTS: At follow-up, 86% of the adolescents were satisfied compared with 78% in the younger adults and 76% in the older adults group (p<.001). According to the global assessment, significantly decreased leg pain was experienced by 87% of the adolescents, 78% of the younger adults, and 71% of the older adults (p<.001). Corresponding figures for back pain were 88%, 73%, and 70%, respectively (p<.001). All groups experienced significant postoperative improvement of VAS leg pain, VAS back pain, ODI, and EQ-5D (all p<.001). CONCLUSIONS: The adolescent age group was more satisfied with the treatment than the adult groups. There was a significant improvement in all age groups after surgery.
