Observational Study
Radiofrequency Treatment of Iliac and Paravertebral Cluneal Nerves for Low Back Pain.
Paravertebral cluneal nerves are constrained within a tunnel consisting of the thoracolumbar fascia and the iliac crest's superior rim as they pass over the iliac crest. Their involvement in low back pain has not been presented previously. ⋯ Cluneal trigger points should be considered in the differential diagnosis of pain in the lower back, flank, lower abdominal, buttock, trochanteric, groin, and thigh area. It is one form of so-called "pseudo-sciatica." The authors' diagnostic injection protocol suggests that most patients with cluneal trigger points may successfully be treated with percutaneous radiofrequency ablation.

Percutaneous cervical nucleoplasty (PCN) is a minimally invasive technique used for the treatment of cervical disc herniation. However, if the lesion is located at the neural foramen, complete access and effective neural decompression are often challenging because of the special anatomical condition of the uncovertebral joint, osteophyte, and facet joint of the cervical foraminal space. ⋯ Although PCN for radiculopathy caused by FCDH is thought to have limitations because of the surrounding bony structure, the clinical outcome seemed favorable. If PCN is not contraindicated, it may be a viable treatment option for CR due to FCDH.

Influence of Handgrip Strength and Psoas Muscle Index on Analgesic Efficacy of Epidural Steroid Injection in Patients With Degenerative Lumbar Spinal Disease.
Handgrip strength (HGS) and psoas muscle index (PMI) are widely used protocols for screening or diagnosing sarcopenia by measuring muscle strength and mass. Epidural steroid injection (ESI) is a common intervention for the treatment of spinal pain; however, the influence of pre-procedural sarcopenic status on therapeutic effects after ESI has not been investigated. ⋯ In the present study, pre-procedural HGS was an independent predictor of analgesic efficacy after ESI in elderly patients with degenerative lumbar spinal disease. However, the PMI was not associated with pain relief after injection.

Legg-Calvé-Perthes disease (LCPD) and slipped capital femoral epiphysis (SCFE) can result in painful deformation of the hip joint with impaired range of motion and early development of secondary osteoarthritis. It has not been investigated whether having LCPD or SCFE is associated with increased use of pain or antidepressant drug prescriptions later in life. ⋯ During childhood, patients with LCPD or SCFE seem to suffer long-term pain and have an increased risk of requiring analgesic medication in adulthood, including opioids. It is important to assess the causes, type, and severity of pain to optimize pain management to counteract possible overuse in these patients. Seemingly, patients with LCPD do not have an increased risk for antidepressant drug therapy in adulthood whereas we did see an increased risk for that in patients with previous SCFE compared with the general population.

Recurrent LDH (rLDH) is one of the most common causes of unsatisfactory outcomes after discectomy, which usually needs secondary surgery and leads to physical and psychological suffering for patients and substantial costs for society. ⋯ This study demonstrated that the recurrence rate of LDH at 5-year follow-up was 6.27% and there was a significant statistical relationship between FO, DHI, and Modic changes and early rLDH. Surgeons should take FO angles, DHI, and Modic change into consideration before surgery to achieve a satisfactory postoperative outcome and a relatively lower early recurrence rate. More patients and further investigation should be taken to assess the risk factors for early rLDH.
