The efficacy of one-stage posterior pedicle screw instrument used in the treatment of non-dystrophic scoliosis in neurofibromatosis type I (NF-1) is unknown. Also, there is no study that has directly compared the results of spinal deformity correction between non-dystrophic scoliosis in NF-1 and adolescent idiopathic scoliosis (AIS). ⋯ Despite the differences in preoperative flexibilities and fusion strategies, non-dystrophic scoliosis in NF-1 can be treated with a satisfied correction rate and progression rate similar to comparable AIS by using the one-stage posterior pedicle screw technique. Dural ectasia or thin pedicles in non-dystrophic scoliosis could make pedicle screw placement challenging.

Posterior three-column spinal osteotomies were shown to be effective to treat severe and stiff kyphoscoliosis. Translations at the site of osteotomy after deformity correction were commonly seen intraoperatively, which might cause potential neurologic deficits. However, this phenomenon was not thoroughly discussed in the current literature. ⋯ The 3D translations are common in posterior three-column spinal osteotomies regardless of anterior strut graft placement. The increase of translation will increase neurologic risks, with GT or FT less than grade II and ST less than grade I being relatively safe.

The aim of spinal deformity correction is to restore the spine's functional alignment by balancing it in both the sagittal and coronal planes. Regardless of posture, the ideal coronal profile is straight, and therefore readily assessable. ⋯ The supra-acetabular line (CSVL1) is better, although not ideal, as compared with the supra-iliac line (CSVL2) in determining coronal balance. Because CSVL1 still cannot be relied on with a high predictive value, it is imperative that future studies continue to identify better intraoperative markers for achieving coronal balance.

We receive a large number of patients with spinal cord injury (SCI) due to penetrating gunshot wounds (GSW) at our national rehabilitation center. Although many patients are labeled American Spinal Injury Association (ASIA) B sensory incomplete because of sensory sparing, especially deep anal pressure, with purported prognostic value, we have not observed a clinical difference from patients labeled ASIA A complete. We hypothesized that sensory sparing, if meaningful, should reduce the occurrence of pressure ulcers. ⋯ ASIA A and B distinctions are not meaningful at spinal cord levels in the cervicothoracic spine due to gunshot wounds as shown by similar occurrence of pressure ulcers and pressure ulcer surgery, and should be treated as if the same. Meaningful decrease of pressure ulcers at cord levels does not occur until there is motor sparing ASIA C or D. Furthermore, cauda equina lumbosacral injuries are a lower risk, which is independent of ASIA grade A-D and statistically equivalent to cord level C or D. Motor sparing at cord levels or any cauda equina level is most determinative neurologically for the occurrence of pressure ulcers or pressure ulcer surgery.

Randomized Controlled Trial Multicenter Study Pragmatic Clinical Trial
Efficacy and safety of urinary catheters with silver alloy coating in patients with spinal cord injury: a multicentric pragmatic randomized controlled trial. The ESCALE trial.
Patients with spinal cord injury (SCI) who carry indwelling urinary catheters have an increased risk of urinary tract infection (UTI). Antiseptic silver alloy-coated (SAC) silicone urinary catheters prove to be a promising intervention to reduce UTIs; however, current evidence cannot be extrapolated to patients with SCI. ⋯ The results of this study do not support the routine use of indwelling antiseptic SAC silicone urinary catheters in patients with SCI. However, UTIs associated to long-term urinary catheter use remain a challenge and further investigations are still needed.
