Spinal News International’s top 10 most popular stories of September 2022


Research showing that minimally invasive surgery is a safe and effective option for those with cerebrospinal fluid leaks was our most read story in September. Additional study findings, on indirect decompression for lumbar spondylolisthesis and ACDF for cervical spondylotic myelopathy, were second and third respectively. Also making the Spinal News International top 10 this month were announcements from RIWOspine, NANISX, NeuraMedica and Gimer Medical.

1. Minimally invasive surgery for spinal cerebrospinal fluid leaks “safe and effective” new study finds

Minimally invasive surgery with tubular retractors and a tailored interlaminar fenestration and, if needed, a transdural approach, is safe and effective for the treatment of spinal cerebrospinal fluid leaks (CSFs), new research has found.

2. Indirect decompression does not provide superior long-term benefits to direct decompression for lumbar spondylolisthesis

Indirect decompression (ID) for the treatment of lumbar spondylolisthesis does not provide superior long-term clinical outcomes compared to direct decompression (DD), new research has suggested. The study found that DD and ID strategies to treat lumbar spondylolisthesis were similar in regards to disability, quality of life, and patient satisfaction outcomes.

3. ACDF offers benefits over PCLF for cervical spondylotic myelopathy but postoperative neck pain improvement comparable

Anterior cervical discectomy and fusion (ACDF) and posterior cervical laminectomy and fusion (PCLF) provide comparable postoperative neck pain improvement at three, 12, and 24 months following three- or four-segment surgery of patients who suffer from cervical spondylotic myelopathy (CSM) and severe neck pain.

4. RIWOspine launches new product line

RIWOspine is expanding its product portfolio to include an innovative segment in the field of minimally invasive spinal surgery. The new evospine product range comprises special implant and instrument solutions for interbody fusion and dorsal stabilisation of the spine, and will be offered in the European market.

5. Spinopelvic alignment should influence treatment option of grade I degenerative spondylolisthesis and stenosis

Lumbar laminectomy with fusion is superior to laminectomy alone in terms of health-related quality of life and reoperation rate at two years postoperatively for patients with sagittal malalignment, represented by high pelvic incidence minus lumbar lordosis (PILL) mismatch, new research, published by David Casper (University of Pennsylvania, Philadelphia, USA) et al in The Spine Journal, has shown.

6. New spine company focused on ambulatory surgery centres formed

Healthcare investment firm KICVentures Group, led by orthopaedic spine surgeon Kingsley Chin (Fort Lauderdale, USA), has announced the formation of a new company, NANISX, which will focus on less exposure surgery (LES) of the spine in ambulatory surgery centres (ASCs).

7. NeuraMedica receives FDA 510(k) clearance for DuraFuse dural clips

NeuraMedica has announced that it has received 510(k) clearance from the US Food and Drug Administration (FDA) for its DuraFuse dural clips which, according to the firm, are designed to allow for fast and secure dural closure.

8. Gimer Medical granted IDE approval for spinal cord stimulation system

Gimer Medical today announced that the company’s spinal cord stimulation (SCS) system was granted conditional investigational device exemption (IDE) approval by US Food and Drug Administration (FDA) on 13 August.

9. Lumbar Synovial Cyst Score a “quick and accurate” tool for predicting synovial cyst recurrence

The Lumbar Synovial Cyst Score model is a quick and accurate tool that can assist in the clinical decision-making process when treating those with lumbar synovial cysts (LSVs), new research—published in the Journal of Neurosurgery: Spine by Paul Page (University of Wisconsin Hospitals and Clinics, Madison, USA) et al—has shown.

10. Timing of tether breakage influences clinical results after VBT

Tether breakage after vertebral body tethering (VBT) leads to a consistent loss of correction when it occurs within the first 12 months. However, it has limited clinical relevance when tether breakage occurs after this timepoint, new research, published by Alice Baroncini (RWTH Aachen University Clinic, Aachen, Germany) et al in the European Spine Journal, suggests.
