To evaluate the radiographic, functional outcomes, complications and surgical specificities of L5 pedicle subtraction osteotomy for fixed sagittal and coronal malalignment. ⋯ PSO of L5 can be a safe and effective technique to treat and correct fixed sagittal imbalance and provide biomechanical stability. The high complication rate mandates a careful assessment of the risk/benefit ratio of such a major surgery. Most patients are satisfied, particularly when sagittal balance is achieved.

Pedicle Subtraction Osteotomy (PSO) is an effective surgical technique for the correction of fixed sagittal malalignment of the spine. It is a demanding technique that requires a long learning curve. The aim of this study is to analyze a surgeon's learning curve for lumbar PSO in relation to the preoperative, perioperative, and postoperative management, with assessment of the global outcome. ⋯ PSO technique has a relatively long learning curve. This study showed that accumulating the experience over the years, while performing cases on a regular basis, is definitely the key in mastering this complex and risky technique, with significant improvements in the perioperative parameters that directly impact the recovery and global outcome.

Low bone mass and a female gender increase susceptibility to the development of degenerative lumbar scoliosis (DLS), which suggests the potential involvement of an osteoporosis-related gene in the pathogenesis of DLS. In the present study, the authors studied the relations between polymorphisms of interleukin 6 (IL-6) gene and DLS in a patient cohort. ⋯ The results of this study suggest that the IL6-572 G/C polymorphism influences LSBMD in Korean DLS patients and the prevalence of the disease.

This study reports the results of a registry data collection project within a secondary care spinal osteopathy service. ⋯ The secondary care spinal osteopathy service demonstrated high satisfaction, few therapeutic complications and positive outcomes on all PROMs. Registry participation has facilitated robust clinical governance and the data support the use of osteopaths to deliver a conservative spinal service in this setting. Registry data collection is a significant administrative and clinical task which should be structured to minimise burden on patients and resources.

Fresh frozen intervertebral disc allograft transplantation has been reported to be a viable treatment option for advanced degenerative disc diseases, but rapid degeneration of the postoperative allograft was found. Loss of nutrient supply is believed to be the most likely inducer because the disc allografts have to endure in an ischaemic environment until the nutrient pathway is re-established. The aim of this study was to focus on the revascularisation of the disc allograft after transplantation in goats. ⋯ Revascularisation of the postoperative disc allograft has been determined, but its pattern was different from that in adult normal discs, suggesting that the typical nutrient diffusion pattern may be affected after transplantation.
