To present the motor deficits and type of neurogenic bladder dysfunction (NBD) in patients with vertebral fractures at thoracolumbar junction. ⋯ Half of the patients had epiconus lesion following thoracolumbar junction fracture, and they had a clinical presentation of flaccid legs and spastic NBD. Patients with L2 fracture had higher LEMS than patients with T11, T12, and L1 fracture. Patients whose LEMS was higher than 20 could all walk functionally. Fracture at the thoracolumbar junction may cause spastic, flaccid, or mixed type NBD, and urodynamic study is an essential tool for the correct diagnosis and management. Ankle spasticity has a high positive predictive value for spastic bladder or sphincter.

Spine fusion is the gold standard treatment in degenerative and traumatic spine diseases. The bone regenerative medicine needs (i) in vitro functionally active osteoblasts, and/or (ii) the in vivo induction of the tissue. The bone tissue engineering seems to be a very promising approach for the effectiveness of orthopedic surgical procedures, clinical applications are often hampered by the limited availability of bone allograft or substitutes. New biomaterials have been recently developed for the orthopedic applications. The main characteristics of these scaffolds are the ability to induce the bone tissue formation by generating an appropriate environment for (i) the cell growth and (ii) recruiting precursor bone cells for the proliferation and differentiation. A new prototype of biomaterials known as "bioceramics" may own these features. Bioceramics are bone substitutes mainly composed of calcium and phosphate complex salt derivatives. ⋯ Human mesenchymal stem cells in combination with biomaterials seem to be good alternative to the autologous or allogenic bone fusion in spine surgery. The cellular model used in our study is a useful tool for investigating cytocompatibility and biological features of HA-derived scaffolds.

Anterior decompression of the craniovertebral junction is reserved to patients with irreducible ventral bulbo-medullary lesions and rapidly deteriorating neurological functions. Classically performed through the transoral approach, the exposure of this region can be now achieved by a minimally invasive endonasal endoscopic approach (EEA). ⋯ Compared with the standard transoral technique, the EEA provides the same good exposure but with potentially less complications. The preservation of the anterior C1 arch can contribute to avoid cranial settling and posterior fusion with its related risk of subaxial instability.

Pre-curved peek rods to support posterior lumbar fusion have been available in the market since 4 years. Potential advantages using this new technology are increased load sharing on the anterior column promoting interbody fusion, reduced stress on bone-screw interface decreasing the rate of screw mobilization and, in the long term, reduced incidence of adjacent level disc degeneration. ⋯ The semi-rigid systems can now be considered a viable option in the lumbar degenerative disease, although clinical evaluations are necessary in the longer term.

The objective of this study was to evaluate the overall incidence and total burden of successful litigation relating to the management of spinal disease across the National Health Service (NHS) in England. ⋯ Spinal litigation remains a source of significant cost to the NHS. The complexity of resolving these cases is reflected in the associated legal costs.
