Conclusions. The primary conclusion is that patients with SCM generally tolerate surgery well and experience few complications. Neurological deterioration is rare except in cases in which retethering occurs, (two patients in this series). Although impaired bowel and bladder function was stabilized or improved and pain was reliably relieved post-operatively, preexisting vertebral column deformities usually progressed after surgery and, in most cases, required spinal fusion.

Abstract Postoperative sagittal-plane cervical spine deformities are a concern when laminectomy is performed for tumor resection in the spinal cord. These deformities appear to occur more commonly after resection of intramedullary spinal cord lesions, compared with laminectomy for stenosis caused by degenerative spinal conditions. Postlaminectomy deformities are most common in pediatric patients with an immature skeletal system, but are also more common in young adults (<25 years of age) in comparison with older adults. The extent of laminectomy and facetectomy, number of laminae removed, location of laminectomy, preoperative loss of lordosis, and postoperative radiation therapy in the spine have all been reported to influence the risk of postlaminectomy spinal deformities. When these occur, patients should be monitored closely with serial imaging studies, because a significant percentage will have progressive deformities. These can range from focal kyphosis to more complicated swan-neck deformities. General indications for surgical intervention include progressive deformity, axial pain in the area, and neurological symptoms attributable to the deformity. Surgical options include anterior, posterior, and combined anterior-posterior procedures. The authors have reviewed the literature on postlaminectomy kyphosis as it relates to resection of cervical spinal cord tumors, and they summarize some general factors to consider when treating these patients.

The overall incidence of pseudarthrosis following long adult spinal deformity instrumentation and fusions to S1 was 23%. Thoracolumbar kyphosis, osteoarthritis of the hip joint, incomplete sacropelvic fixation, thoracoabdominal approach (vs. paramedian approach), and age at surgery (>55 years) significantly increased the risks of pseudarthrosis to an extent that was statistically significant. SRS-24 outcomes scores were adversely affected when pseudarthrosis developed.

Pedicle subtraction osteotomy can provide satisfactory clinical and radiographic outcomes for patients with a minimum 5 year follow-up despite pseudarthrosis revision and no significant changes between 2 years and 5-8 years follow-up. Restoration and maintenance of SVA <8cm was important to the ultimate sagittal reconstruction.

The S-rod/hook offers a simple, effective method of pelvic fixation with avoidance of SI joint, decreased operative time, low implant profile, and with titanium S-hook, MRI compatibility.
In neuromuscular spinal deformities, fixation to the pelvis can be precarious and fraught with problems. The S-rod and S-hook offer effective simple zone 1 fixation to the sacral ala.
