Purpose of study and background. We have previously reported the development of injectable hydrogels for potential disc regeneration (NPgel) or bone formation which could be utilized in spinal fusion (Bgel). As there are multiple sources of mesenchymal stem cells (MSCs), this study investigated the incorporation of patient matched hMSCs derived from adipose tissue (AD) and

Aims. Idiopathic scoliosis is the most common spinal deformity in adolescents and children. The aetiology of the disease remains unknown. Previous studies have shown a lower
Partial facetectomies with pedicle screw instrumentation is widespread and a well described technique for achieving posterior correction of scoliosis. Newton et al. first described the use of the UBS in the posterior correction of AIS in 2014. The aim of this study was to compare the effectiveness of the UBSPO in achieving posterior correction in Type1 AIS as compared to the traditional partial facetectomies. Aim of this study was to assess the effectiveness of USBPO in achieving posterior correction in Type 1 AIS as compared to partial facetectomies. A retrospective review of 40 patients with type 1 AIS who had undergone a posterior correction of scoliosis between 2010 and 2016 was performed. Group A (n=20) consisted of consecutive patients that had partial facetectomies while Group B (n=20) consisted of consecutive patients having UBSPO. Both groups were matched for demographic parameters. Pre and post-operative radiographic parameters and operative data in both groups were compared. The Mann-Whitney U test was used for statistical analysis.Background
Methods
Background. Degeneration of the intervertebral disc (IVD) is a leading cause of lower back pain, and a significant clinical problem. Inflammation mediated by IL-1β and TNF-α drives IVD degeneration through promoting a phenotypic switch in the resident nucleus pulposus (NP) cells towards a more catabolic state, resulting in extracellular matrix degradation.
Background. We have reported an injectable L-pNIPAM-co-DMAc hydrogel with hydroxyaptite nanoparticles (HAPna) which promotes mesenchymal stem cell (MSC) differentiation to

The Royal Liverpool and Broadgreen University Hospital, Liverpool, UK. Plasmacytoma is the localised form of multiple myeloma, which can affect any part of the body including the axial skeleton (Kelly et al, 2006; Ampil et al, 1995). These myelomas/plasmacytomas arise from one malignant clone of cells, which secrete the same type of immunoglobulin. Where the clone of cells remains localised, it is known as plasmacytoma, but when there is spread of the malignancy to multiple

(TB) BMD (g/cm²) and total right hip (TH) BMD were measured by dual
energy x-ray absorptiometry. The proportion of men with osteoporosis
was calculated from TH BMD. There were 215 men (15.1%) with a vertebral
fracture. Those with a fracture had lower TB BMD than those without

with more than three fractures (p = 0.02), those with biconcave

having osteoporosis when having any type of vertebral fracture was
6.1 (95% confidence interval (CI) 3.9 to 9.5) compared with those
without a fracture. A combination of more than three fractures and
compression in the worst quartile had a mean OR of 114.2 (95% CI
6.7 to 1938.3) of having osteoporosis compared with those without
a fracture. We recommend BMD studies to be undertaken in these subcohorts
of elderly men with a vertebral fracture. Cite this article: 2015;97-B:1106–10.
To identify patterns in referral and the management pathway of patients with primary bone tumours of the spine referred to the Orthopaedic Spine Unit in order to recommend ways to improve the service. A retrospective notes and imaging review to evaluate the referral pathway undertaken by patients ending up in the orthopaedic spine unit over a 5 year period according to the recommendations for primary bone tumours. Significant events leading to potential improvement in outcomes were assessed. Recommendations for improvements are suggested. None of the 38 patients evaluated were referred within two weeks of presentation, and only 6 were referred directly to the bone tumour service. Almost half (15/32) of the patients who had an indirect referral pathway had a prior intervention. Five of these had non-surgical, while 10 had surgical interventions outside the tumour centre before their referral. Of these, seven had malignant tumours.Aim
Methods and Results
Patients with peripheral primary bone tumours are often identified and referred at an early stage to a regional tumour service according to established guidelines. In patients with primary bone tumours of the spine, however, the definitive management or outcome of such patients is being prejudiced by preliminary intervention from non-specialist services prior to their referral. Objective: To audit the standards of management of patients with primary bone tumours of the spine referred to a regional tumour service. Retrospective review of case notes and radiology. Subjects: Patients with primary bone tumour of the spine managed at the Orthopaedic Spine Unit with the Regional Bone Tumour Service in Newcastle Upon Tyne Hospitals NHS Trust. Referral to tumour service, prior intervention, operative treatment, survival, factors affecting definitive management 31 of 39 (16 benign, 23 malignant) patients were initially referred from primary care to services These tumours present complex issues regarding their definitive management to optimise outcome. Closer links between departments are required to enable the multidisciplinary management of primary bone tumours of the spine. Prior surgical intervention may compromise cure. Those involved in their management should be encouraged to liaise with their regional bone tumour service to improve outcome.
