Previous studies of variations of the infraorbital foramen (IOF) demonstrated conflicting results regarding to the side and gender in which specific variations occur. Significant differences in some measurement points between genders have been found, whereas, other studies did not report such differences. The presence of an accessory IOF (AIOF) can result in incomplete anesthesia or treatment failure. Previous studies have demonstrated variable results regarding the prevalence of an AIOF ranging from 16.9% to 47.6%. ⋯ The size of the IOF was larger in men than in women. The distance of the IOF from the infraorbital margin was similar for men and women, whereas, the distances between the IOF and the ANS and the IOF and LNA were shorter in women than in men.

Despite percutaneous kyphoplasty (PKP) being widely used to treat osteoporotic vertebral compression fractures (OVCFs), the details of puncture are still controversial. With the development of surgical robots in spine surgery, robotic-assisted PKP surgery will become a promising treatment strategy. ⋯ Robotic-assisted PKP surgery through the unilateral approach to establishing an optimal working channel is a safe and available procedure for treating OVCFs in terms of better distribution of bone cement, high accuracy, good repeatability, and less surgical trauma.

Clinical Effects and Safety of the Use of Methylene Blue for the Treatment of Lumbar Facet Joint Syndrome.
Lumbar facet joint syndrome (LFJS) has been suggested to be a main source of low back pain. Methylene blue (MB), an inhibitor of nitric oxide synthesis with potential analgesic and anti-inflammatory properties, has been widely applied for a variety of pain-related diseases. However, no studies have been conducted on the treatment of LFJS patients using MB. ⋯ Ultrasound-guided intra-articular MB injection is a safe and effective therapy for patients with LFJS. Intra-articular injection with MB can significantly reduce pain intensity, improve patient lumbar function, pain-related depression and sleep quality, increase total effective rate with no severe adverse side effects.

Spinal cord stimulation (SCS) is an accepted treatment for certain chronic pain syndromes. It is imperative that patients undergo a stimulation screening trial. For trial stimulation, typically patients undergo a percutaneous lead placement. Due to technical considerations, there exists a subset of patients who are not candidates for a percutaneous trial. ⋯ Patients, who have either failed or are deemed suboptimal for percutaneous trialing for spinal cord stimulation, should be considered for open paddle lead trialing. A multidisciplinary approach improves communication and helps to identify that subset of patients who otherwise may be left to pursue conservative measures only.
