During the last decades, platelet-rich plasma has been studied for the treatment of multiple chronic pain conditions, in addition to being employed in the enhancement of healing after tissue injury. ⋯ Future research addressing the utilization of platelet-rich plasma in the treatment of chronic pain conditions should focus on shedding light on the following major questions: a) Is there a dose-effect relation between the platelet count and the clinical efficacy of the preparation?; b) What pathology determinants should be considered when selecting between leukocyte-enriched and leukocyte-depleted concentrates?; c) What is the role of platelet activation methods on the clinical efficacy of platelet-rich plasma?; d) Is there an optimal number of injections and time frame for application of multiple injection treatment cycles?; e) Does the addition of local anesthetics affect the clinical efficacy of platelet-rich plasma?; and f) Is there potential for future platelet-rich plasma applications for the treatment of neuropathic pain of peripheral origin?

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.

Observational Study
Computerized Characterization of Spinal Structures on MRI and Clinical Significance of 3D Reconstruction of Lumbosacral Intervertebral Foramen.
Segmentation of spinal structures is important in medical imaging analysis, which facilitates surgeons to plan a preoperative trajectory for the transforaminal approach. However, manual segmentation of spinal structures is time-consuming, and studies have not explored automatic segmentation of spinal structures at the L5/S1 level. ⋯ The 3D-UNet model developed in this study based on deep learning can effectively and simultaneously segment VBSs and IVDs at L5/S1 level formMR images, thereby enabling rapid and accurate 3D reconstruction of LIVF models. The method can be used to segment VBSs and IVDs of spinal structures on MR images within near-human expert performance; therefore, it is reliable for reconstructing LIVF for L5/S1 LTRFA.

Cervical facet joint pain is often managed with either cervical radiofrequency neurotomy, cervical medial branch blocks, or cervical intraarticular injections. However, the effectiveness of each modality continues to be debated. Further, there is no agreement in reference to superiority or inferiority of facet joint nerve blocks compared to radiofrequency neurotomy, even though cervical facet joint radiofrequency neurotomy has been preferred by many and in fact, has been mandated by the Centers for Medicare and Medicaid Services (CMS), except when radiofrequency cannot be confirmed. Each procedure has advantages and disadvantages in reference to clinical utility, outcomes, cost utility, and side effect profile. However, comparative analysis has not been performed thus far in the literature in a clinical setting. ⋯ In this study, outcomes of cervical therapeutic medial branch blocks compared to radiofrequency neurotomy demonstrated significantly better outcomes with significant pain relief with similar costs for both treatments over a period of one year.

Multicenter Study Observational Study
Radiation Doses for Different Approaches of Fluoroscopy-Guided Epidural Injections: An Observational Clinical Study.
Although fluoroscopy-guided interventional therapies have declined in recent years, radiation exposure remains a critical issue for both patients and medical staff. Radiation exposure varies according to the physicians' experience, procedure time, patients' body mass index (BMI), imaging techniques, and the type of procedure performed. ⋯ Radiation dose levels and procedure times of 4 approaches of epidural injections were obtained from 3,711 procedures performed in a university hospital pain medicine clinic. BMI of patients was taken into account with the dose levels of injections given per BMI. Multicenter research with standardized techniques will assure more reliable reference levels, which will guide pain physicians to self-assess their own levels of radiation exposure.
