Background. It has become increasingly important to conduct studies assessing clinical outcomes, reoperation rates, and revision rates to better define the indications and efficacy of lumbar spinal procedures and its association with symptomatic adjacent segment degeneration (sASD). Adjacent segment degeneration (ASD) is defined as the radiographic change in the intervertebral discs adjacent to the surgically treated spinal level. SASD represents adjacent segment degeneration which causes pain or numbness due to post-operative spinal instability or nerve compression at the same level. The most common reason for early reoperation and late operation is sASD, therefore is in our best interest to understand the causes of ASD and make steps to limit the occurrence. Method. A comprehensive literature search was performed selecting Randomized controlled trials (RCTs) and retrospective or prospective studies published up to December 2023. Meta-analysis was performed on 38 studies that met the inclusion criteria and included data of clinical outcomes of patients who had degenerative disc disease, disc herniation, radiculopathy, and spondylolisthesis and underwent lumbar fusion or motion-preservation device surgery; and reported on the prevalence of ASD, sASD, reoperation rate, visual analogue score (VAS), and Oswestry disability index (ODI) improvement. Results. When compared to fusion surgery, a significant reduction of ASD, sASD and reoperation was observed in the cohort of patients that underwent motion-preserving surgery. Conclusion. Dynamic fusion constructs are treatment options that may help to prevent sASD. Conflicts of interest. This research was funded by Paradigm Spine. Sources of funding. Paradigm Spine

Background. Routine imaging (radiography, CT, MRI) provides no health benefits for low back pain (LBP) patients and is not recommended in clinical practice guidelines. Whether imaging leads to increased costs, healthcare utilization or absence from work is unclear. Purpose. To systematically review if imaging in patients with LBP increases costs, leads to higher health care utilization or increases absence from work. METHODS. Randomized controlled trials (RCTs) and observational studies (OSs), comparing imaging versus no imaging on targeted outcomes were extracted from medical databases until October 2017. Data extraction and risk of bias assessment was performed independently by two reviewers. The quality of the body of evidence was determined using GRADE methodology. Results. Moderate quality evidence (1 RCT; n=421) supports that direct costs increase for patients undergoing radiography. Low quality evidence (3 OSs; n=9535) supports that early MRI leads to a large increase in costs. Moderate quality evidence (2 RCTs, 6 OSs; n=19392) supports that performing MRI, radiography or CT is associated with increased healthcare utilization. Two RCTs (n=667) showed no significant differences between radiography or MRI groups compared with no imaging groups on absence from work. However, the results of two observational studies (n=7765) did show significantly greater absence from work in the imaging groups compared to the no imaging-groups. Conclusions. Imaging in LBP is associated with higher medical costs and increased healthcare utilisation. There are indications that it also leads to higher absence from work. No conflicts of interest.

Background. Chronic pain is a complex condition that demonstrates better outcomes in multidisciplinary rehabilitation, typically delivered to groups of patients by tertiary healthcare teams. An inter-disciplinary pain management course for individual patients was developed to increase the scope of physical therapists working in primary care by integrating osteopathic manual therapy with psychological interventions from Acceptance and Commitment Therapy (ACT), a form of ‘3rd wave’ Cognitive Behaviour Therapy. Method and Results. A single cohort study with pre-course (n=180) and post-course (n=79) self-report measures (44% response rate) evaluated six week interventions which combined individual manual therapy with self-management, delivered by teams of qualified and student osteopaths. Data included: quality of life (European Quality of Life Questionnaire); pain, mood and coping (Bournemouth Questionnaire); psychological flexibility (Revised Acceptance and Action Questionnaire); and mindfulness (Freiburg Mindfulness Inventory). Participants were predominantly female (68%), unemployed (59%), with an average age of 49 and pain duration of more than 12 months (86%). Commonly reported symptoms were low back pain (82%), neck pain (60%) and multiple sites (86%). At six months, there were statistically significant improvements in all four outcome measures (p<0.0005), with promising effect sizes in quality of life and pain coping (r=0.52) which appeared to be mediated by changes in psychological flexibility. Conclusions. This innovative, integrated, patient-centred chronic pain management course demonstrated promising outcomes when delivered by osteopaths with varying experience. Randomised clinical trials are now needed to assess outcomes in comparison with standard care, and optimal ways of training physical therapists to deliver effective psychological interventions.

Aims

In a multicentre, randomised study of adolescents undergoing posterior spinal fusion for idiopathic scoliosis, we investigated the effect of adding gelatine matrix with human thrombin to the standard surgical methods of controlling blood loss.
