Spinal cord stimulation (SCS) is being increasingly used in non-surgical intractable low back pain. This study was designed to evaluate the efficacy of high-dose (HD) SCS utilizing sub-perception stimulation with higher frequency and pulse width in non-surgical predominant low-back pain population at 12 months. ⋯ This study demonstrates that anatomical placement of leads with sub-perception HD stimulation could provide effective pain relief in patients who are not candidates for spinal surgery.

Anterior cutaneous nerve entrapment syndrome (ACNES) is a painful condition that can be refractory in a small percentage of patients. Abdominal pain caused by thoracic nerve entrapment in the abdominal wall characterizes ACNES. In the small number of refractory patients to all standard treatments, medication overuse and abuse are serious problems. Dorsal root ganglion (DRG) stimulation might be a good treatment to improve pain scores and to lower medication use. ⋯ This case series shows that DRG stimulation might be a very good treatment for refractory ACNES.

The purpose of this research was to investigate the outcomes between unilateral biportal endoscopic discectomy (UBE) and percutaneous endoscopic lumbar discectomy (PELD) for the single L4/5-level lumbar disk herniation (sLDH). ⋯ The UBE for sLDH yielded similar clinical outcomes to PELD as minimally invasive surgeries; however, PELD is superior to UBE in terms of intraoperative blood loss, operative time, postoperative hospitalization, and short-term postoperative pain relief. The advantages and disadvantages of the two surgeries should be circumspectly balanced when evaluating a patient for a minimally invasive surgery for sLDH, selecting the most appropriate surgical method for patients.

Complex regional pain syndrome type I (CRPS I) is a multifactorial condition that is related to neural damage, and leads to chronic neuropathic pain. Due to its multifactorial nature, there are many methods that have been recruited for its management. Most of them limit the symptoms to some degree, but the most effective of them so far seems to be blockade of the sympathetic innervation of the region. ⋯ Blockade of the stellate ganglion was performed with local anesthetic and dexamethasone. After the stellate ganglion blockade was marked as successful in relieving her symptoms, cryoneurolysis was performed which was very effective. There are not many cases that have been treated with cryoneurolysis, and this is what makes this case interesting.
