Einleitung: Das Raynaud-Phänomen (RP) ist ein episodisch auftretender Vasospasmus der peripheren Arterien (reversible Blässe, Zyanose und oder Erythem), der Schmerzen, Parästhesien und manchmal Ulzerationen an Fingern und Zehen verursachen kann [ref:1].

Posterior instrumentation is an established treatment for a range of spinal disorders. Material failure is not uncommon, and the indications for a revision are very heterogeneous. This study aimed to evaluate the indications and timing for early revision spinal surgery due to material failure. In this retrospective, single-center cohort study, patients underwent spinal posterior instrumentation between January 2017 and July 2019. They were followed up at 3, 12, and 18 months postoperatively. The time of onset of material failure which led to revision surgery was analyzed. In addition, the relationship between the indications for revision surgery and independent variables was examined using a multivariate logistic regression model. A total of one hundred thirty-five patients were enrolled. Radiolucent zones were found in 30 patients (20%) after 3 months, whereas 48 patients (31%) had radiolucent zones after 12 months. Revision surgery was performed in 13 patients (8.5%). The peak time for revision due to instability was within the first four months of the primary surgery. Multivariate analysis revealed that location, pathology, ASA score, and smoking had no significant impact on the indication for revision surgery, and neither did BMI (P = .042). Non-fusion (P = .007) and radiolucent zones (P = .004), in combination with increased pain (P = .006), were predictors for revision. Our data show that the peak time for early revision of material failure after posterior instrumentation was within the first 4 months of primary surgery. The abnormalities (e.g., radiolucent zones) surrounding the screws without fusion, including persistence of pain, were predictors for revision surgery.

Objective: Spinal Cord Stimulation (SCS) may provide pain relief in these patients. During SCS treatment, paraesthesia is generally experienced by the patient. The significance of paraesthesia on treatment efficacy, the possible role of placebo effects, and the importance of electrode position are not[for full text, please go to the a.m. URL], 67.

Objective: ONS has been shown to provide pain relief in patients with refractory primary headache disorders. It is also less invasive than other surgical approaches; however, drawbacks have been reported, including technical issues with implantable components and lack of efficacy of the treatment.

Objective: DRG stimulation is an emerging therapy for targeting radicular pain syndromes, which are hard to treat by conventional spinal cord stimulation. Traditionally the implant procedure requires intensive intra-operative testing of the paresthesia coverage in awake surgery setting. Often patients[for full text, please go to the a.m. URL], 66.
