“…Experimental animal studies have found magnetic resonance imaging (MRI) changes due to denervation and myonecrosis of the posterior spinal musculature consequent to posterior surgery and retraction duration [10,11]. Human MRI studies have also detected posterior spinal muscle abnormalities [12][13][14][15].…”

Purpose To compare single-level circumferential spinal fusion using pedicle (n = 27) versus low-profile minimally invasive facet screw (n = 35) posterior instrumentation. Method A prospective two-arm cohort study with 5-year outcomes as follow-up was conducted. Assessment included back and leg pain, pain drawing, Oswestry disability index (ODI), pain medication usage, self-assessment of procedure success, and [1-year postoperative lumbar magnetic resonance imaging. Results Significantly less operative time, estimated blood loss and costs were incurred for the facet group. Clinical improvement was significant for both groups (p \ 0.01 for all outcomes scales). Outcomes were significantly better for back pain and ODI for the facet relative to the pedicle group at follow-up periods [1 year (p \ 0.05). Postoperative magnetic resonance imaging found that 20 % had progressive adjacent disc degeneration, and posterior muscle changes tended to be greater for the pedicle screw group. Conclusion One-level circumferential spinal fusion using facet screws proved superior to pedicle screw instrumentation.

“…Paradoxically, some operations designed to treat these various spinal disorders actually disrupt these muscles and, in turn, may lead to substantial functional deficits [12][13][14][15] or various pain syndromes [16][17][18] . Minimally invasive spine surgery techniques strive to minimize surgical trauma to these muscles, thereby preserving their function 19 .…”

“…Using a computer-based image analysis system, we combined MRI data to measure the cross-sectional area of PVM. Gille et al 5 reported that fatty involution of the erector spinae muscles proximal to the decompression level was negligible, although it was more marked distal to the arthrodesis. The vascularization and innervation of these muscles are segmented with numerous vertical anastomoses.…”

“…From several anatomical and functional studies of PVM, 4,5,14,15,18 it is clear that muscle damage can result in postoperative PVM dysfunction. Intraoperative damage to the posterior supporting structures can lead to irreversible PVM atrophy.…”

Surgical outcomes of modified lumbar spinous process–splitting laminectomy for lumbar spinal stenosis

The lumbar spinous process–splitting laminectomy (LSPSL) procedure was developed as an alternative to lumbar laminectomy. In the LSPSL procedure, the spinous process is evenly split longitudinally and then divided at its base from the posterior arch, leaving the bilateral paravertebral muscle attached to the lateral aspects. This procedure allows for better exposure of intraspinal nerve tissues, comparable to that achieved by conventional laminectomy while minimizing damage to posterior supporting structures. In this study, the authors make some modifications to the original LSPSL procedure (modified LSPSL), in which laminoplasty is performed instead of laminectomy. The purpose of this study was to compare postoperative outcomes in modified LSPSL with those in conventional laminectomy (CL) and to evaluate bone unions between the split spinous process and residual laminae following modified LSPSL. Forty-seven patients with lumbar spinal stenosis were enrolled in this study. Twenty-six patients underwent modified LSPSL and 21 patients underwent CL. Intraoperative blood loss and surgical duration were evaluated. The Japanese Orthopaedic Association (JOA) scale scores were used to assess parameters before surgery and 12 months after surgery. The recovery rates were also evaluated. Postoperative paravertebral muscle atrophy was assessed using MRI. Bone union rates between the split spinous process and residual laminae were also examined. The mean surgical time and intraoperative blood loss were 25.7 minutes and 42.4 ml per 1 level in modified LSPSL, respectively, and 22.7 minutes and 29.5 ml in CL, respectively. The recovery rate of the JOA score was 64.2% in modified LSPSL and 68.7% in CL. The degree of paravertebral muscle atrophy was 7.8% in modified LSPSL and 22.2% in CL at 12 months after surgery (p < 0.05). The fusion rates of the spinous process with the arcus vertebrae at 6 and 12 months in modified LSPSL were 56.3% and 81.3%, respectively. The modified LSPSL procedure was less invasive to the paravertebral muscles and could be a laminoplasty; therefore, the modified LSPSL procedure presents an effective alternative to lumbar laminectomy.
