“…In addition, patients with moderate or severe DS, especially with dynamic instability, are at risk of posterior implant movement after surgery. Therefore, these two types of patients with LSS are not appropriate candidates for IPDs [ 34 , 40 ].…”

Decompression Using Minimally Invasive Surgery for Lumbar Spinal Stenosis Associated with Degenerative Spondylolisthesis: A Review

Lumbar spinal stenosis (LSS), which often occurs concurrently with degenerative spondylolisthesis (DS), is a common disease in the elderly population, affecting the quality of life of aged people significantly. Notwithstanding the frequently good effect of conservative therapy on LSS, a minority of the patients ultimately require surgery. Surgery for LSS aims to decompress the narrowed spinal canals with preservation of spinal stability. Traditional open surgery, either pure decompression or decompression with fusion, was considered effective for the treatment of LSS with or without DS. However, the long-term clinical outcomes of traditional open surgery are still unclear. Moreover, the disadvantages of conventional open surgery are extensive, examples including tissue injuries or secondary instability, with Jun Zhang, Tang-Fen Liu, and Hua Shan contributed equally to the work.

“…Spinal interventional radiology, thanks to the high procedural success, together with its minimal invasiveness and a high safety profile, has been gaining an increasingly wider field of applications, either for degenerative, neoplastic, and inflammatory pathology, with several techniques, procedures, implantable materials, and injectable drugs available (4)(5)(6)(7)(8)(9)(10).…”

“…Interspinous spacer implantation is a minimally invasive, indirect decompression treatment option available for patient with LSS and symptomatic neurogenic claudication without evidence of spondylolisthesis (7,8). Under fluoroscopic guidance, the device is implanted between the spinous processes at one or 2 levels; implantation can be performed under local and intravenous sedation anesthesia and as a same-day procedure (9). Additionally, it has been shown to have faster procedural time with less blood loss compared to surgery (10).…”

Background: Lumbar spinal stenosis with neurogenic claudication can be a debilitating condition, affecting quality of life. Interspinous spacer implantation is a minimally invasive procedure for treatment of lumbar spinal stenosis with neurogenic claudication and associated symptoms by minimizing spinal extension and therefore neural compression. Case Presentation: This case series presents 4 cases of patients with multilevel stenosis, most radiographically severe in the lumbar region, all who received interspinous spacers at L3-4 and L4-5 after minimal improvement in symptoms with conservative management including epidural injections. In all 4 cases, patients reported improved standing and gait but limited improvement in pain and overall function after interspinous spacer implantation. Each patient underwent repeat epidural injections at or below the level of the interspinous spacer with significant improvement in pain for up to 6 months. Conclusion: Our conclusion is that either postspacer epidural injections helped reduce inflammation associated with the implantation procedure, or the spacer maintained an open space to allow the injectate to permeate areas with the most stenosis and help reduce inflammation and therefore pain. Key words: Epidural injection, interspinous process decompression, interspinous spacer, interspinous spacer implant, low back pain, lumbar spinal stenosis, neurogenic claudication, spinal stenosis
