We report the case of a 44-year-old man who was found to have metastatic thymoma to his lumbar spine presenting as a spontaneous epidural haematoma. The man presented with back pain and cauda equina like symptoms in the absence of trauma, antiplatelet or anticoagulant agents. ⋯ To the best of our knowledge, this is the first such case of metastatic thymoma to the lumbar spine presenting as a spontaneous epidural collection. We believe, in all patients with spontaneous spinal epidural haematoma and a background of malignancy, histopathological analysis should be sought.

To investigate whether obesity is associated with worse patient-reported outcomes following surgery for degenerative lumbar conditions. ⋯ Body mass index ≥35 is associated with worse baseline and 12-month PROs, however, there was no difference in change scores across BMI groups. Controlling for important co-variables, BMI greater than 35 was not an independent predictor of worse PROs at 12 months.

To investigate volumetric changes in lumbar disc herniation (LDH) using three-dimensional measurements obtained by magnetic resonance imaging (MRI) and to identify possible factors affecting such changes. ⋯ We observed that LDH is a dynamic disease and that a herniated disc is not always spontaneously resorbed, in contrast to what has been reported previously. Alleviation of clinical symptoms can be achieved via conservative treatment even if the volume of the herniated disc changes. Spinal surgeons should not only present an option of initial non-surgical treatment to LDH patients but should also inform them that the LDH may change in size during daily activity or exercise.

Assessment of bony fusion following anterior cervical interbody fusion (ACIF) is usually done by plain film or CT. We present the first clinical application of Cone-Beam CT (CBCT) to evaluate bony fusion after ACIF. ⋯ CBCT provides high-resolution cross-sectional imaging of the cervical spine after ACIF. For the first time, in vivo evaluation of the bone graft filler within the centre of the circumferentially radiodense cage and detailed cross-sectional evaluation of bone fusion was achieved. Confirmation of these promising outlooks of CBCT in a large cohort of ACIF patients is needed with regard to routine clinical application and evaluation of different interbody devices.

Lumbosacral hemivertebra poses a unique problem because it can cause gross imbalance and progressive compensatory thoracolumbar deformity. Previous studies have reported lumbosacral hemivertebra resection through a combined anterior and posterior approach, but there have been no reports on the results and complications of hemivertebra resection via a posterior-only procedure and short fusion with large series of patients. ⋯ In summary, our results showed that one-stage HV resection and short segment fusion by a posterior approach can offer excellent scoliosis correction and trunk shift improvement without neurological complications, while saving motion segments as much as possible. This strategy is not only corrective of the deformity but also preventive of compensatory curve progression, thus avoiding long lumbar fusion.
