Observational Study
Development of Symptomatic Adjacent and Remote Level Compression Fractures Following Balloon-assisted Kyphoplasty in a Series of 1,318 Patients.
Balloon-assisted kyphoplasty (BAK) is a minimally invasive procedure to treat vertebral compression fractures (VCF). BAK not only restores vertebral height and corrects kyphotic deformity by cement augmentation, but it also may alter spinal biomechanics, leading to subsequent adjacent level VCFs. ⋯ Symptomatic post-BAK VCFs are infrequent and may occur long after the initial procedure. Nearly two-thirds of subsequent fractures in our study occurred adjacent to the initially treated level; almost every patient who suffered thoracic and lumbar fractures at the same time developed an adjacent level second fracture. Additionally, osteoporosis and chronic corticosteroid use were associated with adjacent level fractures in patients who underwent surgery for degenerative indications.

A pain drawing is a self-administered assessment that requires the patient to shade in on a body chart the areas in which he or she experiences pain, regardless of the intensity. Pain drawings have already been validated in several adult populations. ⋯ Adolescents complaining musculoskeletal pain showed reliability in reporting pain extent and location using pain drawings.

Spinal cord stimulation is an established technique wherein diverse electrode types are strategically implanted within the spinal epidural space for neuromodulation. Traditional percutaneous puncture cylindrical electrodes (PEs) are predominantly implanted by interventionalists utilizing a percutaneous technique under the monitor of radiation, which is a nonvisualized procedure. ⋯ With the assistance of percutaneous spinal endoscopy, introducer needles can be punctured through the ligamentum flavum at the anticipated interlaminar window locus under direct visualization, improving the convenience of the puncture and reducing fluoroscopic exposure. It is a viable alternative for surgeons from diverse training backgrounds to implant PEs, particularly benefiting those well-versed in endoscopic spine surgery techniques.

Melatonin, one of the most versatile hormones in the body, is well appreciated in managing circadian rhythm and for antioxidant properties. Produced in the pineal gland and within mitochondria, melatonin influences many physiologic processes through receptor mediated and direct effects. ⋯ Based on the present systematic review, melatonin plays a critical role in sleep, but evolving studies have demonstrated substantive roles in mitigating degenerative conditions in various tissues, including IVD degeneration. Ongoing studies will better clarify the role of melatonin as a potential therapeutic agent, including the targeted delivery to various body regions.

Since 1992, when the Accreditation Council of Graduate Medical Education (ACGME) acknowledged pain medicine as a subspecialty, the field has experienced significant growth in its number of programs, diversity of sponsoring specialties, treatment algorithms, and popularity among applicants. These shifts prompted changes to the educational model, overseen by program directors (PDs) and the ACGME. The pool of pain fellowship applicants also changed during that period. ⋯ This survey demonstrated that procedural volume and diversity were important factors in trainees' decisions to apply to the field of pain medicine; however, extending the duration of a pain fellowship was not an option survey participants favored. Therefore, PDs and educational stakeholders in pain fellowship training need to develop creative strategies to maintain competitive applicants' interest while they adapt to our evolving field.
