Cold hypersensitivity in the hands and feet (CHHF) is a disease characterized by abnormal cold in the limbs with limited treatment options. Compared to traditional drug therapy, lumbar sympathectomy is a new minimally invasive surgical method for treating CHHF. ⋯ Lumbar sympathetic RFT had better long-term efficacy, lower recurrence, and fewer complications than the chemical lumbar sympathectomy when treating CHHF.

Optimal approaches for treating surgical spine pathology in very geriatric patients, such as those over the age of 80, remain unclear. ⋯ Endoscopic spine surgery offers octogenarians a safe and effective option for the treatment of lumbar degenerative spine disease and may represent a valuable treatment strategy in a growing patient population.

Sacroiliac joint (SIJ) pain is a common etiology of chronic lower back pain. Treatment of persistent sacroiliac joint pain may entail intraarticular steroid injections and lateral branch radiofrequency neurotomy. ⋯ Both SIJ intraarticular steroid injections and SIJ lateral branch radiofrequency neurotomy demonstrated significant pain relief for patients with SIJ pain. SIJ lateral branch radiofrequency neurotomy provided a longer duration of pain relief (82 days) versus SIJ intraarticular steroid injection (38 days).

Spinal cord stimulation (SCS) is a common treatment for neuropathic pain. There are 2 main categories of SCS leads: paddle leads and cylindrical leads. Paddle leads have reduced long-term complications and provide better coverage of target dermatomes when compared to cylindrical leads. However, insertion of a paddle lead requires invasive surgery that comes with significantly higher costs and more short-term complications, such as postoperative pain and infection. In contrast, cylindrical leads can be inserted minimally invasively using percutaneous techniques but provide less coverage of targeted dermatomes and have a higher tendency to migrate from intended neuronal targets. ⋯ The unique shape memory property of nitinol shows promise in allowing cylindrical spinal cord stimulation leads to expand into a more optimal geometry within the epidural space. By having a body temperature-dependent geometry change, nitinol-based cylindrical leads could reduce lead migration, increase dermatomal coverage, and increase electrode density while maintaining the advantages of minimally invasive insertion.
