To analyze changes in sagittal spinopelvic parameters (SSPs) after surgical treatment of Scheuermann's Kyphosis (SK). ⋯ We confirm the positive effect of surgery by Ponte osteotomy and posterior spinal fusion on TK and LL in patients with SK. In our experience, pelvic parameters did not change after surgery.

Comparative Study Clinical Trial
Clinical and radiological features of hybrid surgery in multilevel cervical degenerative disc disease.
Although several studies have established the safety and efficacy of cervical disc arthroplasty (CDA) as compared to anterior cervical discectomy and fusion (ACDF), few studies have investigated the role of hybrid surgery (HS) that incorporates ACDF and CDA techniques in multilevel cervical degenerative disc disease (MLCDDD). ⋯ HS is an effective, reliable, and safe procedure for the treatment MLCDDD. Such a surgical construct is comparable to ACDF and CDA in terms of safety and feasibility. However, large, randomized controlled trials are warranted.

The motion at the non-ossified segment of the ossification of the posterior longitudinal ligament (OPLL) is thought to be highly correlated to aggravation of symptoms of myelopathy. The rationale for posterior decompression with instrumented fusion (PDF) surgery is to limit the motion of the non-ossified segment of OPLL by stabilization. The purpose of the present study was to elucidate the course of bone union and remodelling of the non-ossified segment of thoracic OPLL (T-OPLL) after PDF surgery. ⋯ The results of this study showed that remodelling of the OPLLs, following fusion of non-ossified segment of OPLLs, resulted in a decreased OPLL thickness, with potential for a reduction of spinal cord compression.

Combined intraoperative monitoring (IOM) of transcranial electric motor-evoked potentials (tce-MEPs) and somatosensory-evoked potentials (SSEPs) is safe and effective for spinal cord monitoring during scoliosis surgery. However, the literature data regarding the reliability of spinal cord monitoring in patients with neuromuscular scoliosis are conflicting and need to be confirmed. ⋯ Multimodalitary IOM is safe and effective to detect impending spinal cord and peripheral nerves dysfunction in neuromuscular scoliosis surgery. However, the interpretation of neurophysiological data may be challenging in such patients, and the rate of false-positive results is high when pre-operatory motor deficits are severe.

The treatment of adult scoliosis is a challenge especially in patients over 50 years old with severe, rigid curves in whom the use of vertebral osteotomies may be necessary to correct the deformity. The aim the study was to analyse the perioperative complications related to vertebral osteotomies in elderly treated for spinal deformity. ⋯ Previous studies have shown increased complication rates with vertebral osteotomies in elderly patients, our experience support this evidence. Our study demonstrates a high incidence of intraoperative complication rate in elderly patients underwent a PSO. PSO is a demanding technique to be considered in very selected and motivated patients who must be carefully informed about the risks of the procedure.
