A cross-sectional study of the data retrospectively collected by chart review. ⋯ Careful insertion of pedicle screws is necessary, especially at C3 to C5, even when using a CT-based navigation system. Pedicle screws tend to be laterally perforated.

Review Case Reports
Pedicle subtraction osteotomy for the treatment of chin-on-chest deformity in a post-radiotherapy dropped head syndrome: a case report and review of literature.
Chin-on-chest deformity is a rare and severe condition mostly related with ankylosing spondylitis, traumas and/or cervical spine surgery. We present a case of 69 years old woman with a rare form of chin-on-chest secondary to dropped head syndrome (DHS), developed after radiotherapy for Hodgkin disease. In addition, we reviewed the few publications about this specific condition; management and surgical treatment of DHS are discussed. ⋯ DHS is a very rare post-radiotherapy complication; there is lack of evidences in literature about its management. The only definitive treatment seems to be surgical intervention. PSO is a valid therapeutic option when fixed chin-on-chest deformity occurs; although it is a demanding technique and it presents high rate of complications, the actual neurological monitoring methods provide more intraoperative safety.

To report our early experience with minimally invasive surgery (MIS) in low-dysplastic lumbosacral lytic spondylolisthesis (LDLLS), and to analyze the impact of surgery on postoperative spino-pelvic and sacro-pelvic parameters. ⋯ This series demonstrates that MIS is feasible and effective for LDLLS, as witnesses by the satisfactory clinical results maintained at medium-term follow-up. We submit that TLIF is a valid option but an adequately sized and positioned interbody cage is a key factor to allow satisfactory restoration of segmental lordosis.

Spinal deformities and pathologies of the spinopelvic junction are conditions affecting up to 60-70 % of the general aging population. In this review, we discuss the more recent knowledge on sagittal balance and its clinical implications. ⋯ Failure to restore normal sagittal alignment in patients primarily operated for other than deformity results in unacceptable rates of poor results and revision surgery.

Randomized Controlled Trial
A prospective randomised controlled trial to assess the efficacy of dynamic stabilisation of the lumbar spine with the Wallis ligament.
This prospective randomised control study is to demonstrate whether or not there is a clinical benefit from inserting a Wallis implant on the functional recovery of patients who have undergone lumbar decompression surgery. ⋯ The Wallis implant is a safe medical device. This study revealed a reduction in pain and functional disability in patients treated with decompression surgery for lumbar stenosis, with or without Wallis. The Wallis group improved more, but it was not statistically significant. The risk of complications is lower than other interspinous devices.
