Comparative Study Clinical Trial
Teriparatide versus low-dose bisphosphonates before and after surgery for adult spinal deformity in female Japanese patients with osteoporosis.
Complications of adult spinal deformity surgery are problematic in osteoporotic individuals. We compared outcomes between Japanese patients treated perioperatively with teriparatide vs. low-dose bisphosphonates. ⋯ Perioperative administration of teriparatide is more effective than that of low-dose bisphosphonates in preventing complications and maintaining fusion rates in osteoporotic Japanese females with spinal deformities undergoing surgery.

Majority of the previous studies compared lumbar spinal stenosis (LSS) and lumbar disc herniation (LDH) patients for analyses of LFH. However, the separation of normal/hypertrophied LF has often been ambiguous and the severity of hypertrophic activity differed. Here, we present a novel analysis scheme for LFH in which myofibroblast is proposed as a major etiological factor for LFH study. ⋯ We conclude that the transition of fibroblast to myofibroblasts via TGF-β pathway is a key linker between inflammation and fibrosis in LFH mechanism.

Case Reports
New method for correction of lumbo-sacral kyphosis deformity in patient with high pelvic incidence.
Technical note. ⋯ Bilateral longitudinal sacral osteotomy appears to be a safe and efficient way of correcting the sagittal imbalance caused by an extremely high PI. Although technically demanding, it achieves good radiological and functional outcomes and avoids entering the spinal canal.

To investigate the suitability of the transpedicular approach (TPA) in a sheep model of IVD regenerative strategies METHODS: 24 IVD from four sheep were used. TPA and biopsies of the Nucleus pulposus (NP) were performed in 18 IVD (6 IVD control). Seven discographies were performed to assess the feasibility of injecting contrast agent. MRI, micro-CT scan, and histological analyses were performed and the accuracy of the TPA was evaluated. The effects on the vertebra and endplates were analyzed. ⋯ TPA induces damage to the endplates, and it may lead to neurological impairment and leakage of injected materials into the systemic circulation. These adverse effects must be fully considered before proceeding with TPA for IVD regenerative strategies.

Adult spinal deformity (ASD) causes severe disability, reduces overall quality of life, and results in a substantial societal burden of disease. As healthcare is becoming more value based, and to facilitate global benchmarking, it is critical to identify and standardize patient-reported outcome measures (PROMs). This study aims to identify the current strengths, weaknesses, and gaps in PROMs used for ASD. ⋯ Outcome domains related to mobility and pain were well represented. We identified a gap in current outcome measures regarding neurological and pulmonary function. In addition, no outcome domains were measured in the ICF chapter body structure. These results will serve as a foundation for the process of seeking international consensus on a standard set of outcome domains, accompanied PROMs and contributing factors to be used in future clinical trials and spine registries.
