“…There are two variants of cervical discectomy that are in clinical use; namely, the standard or open method and the minimally-invasive or percutaneous method [1,[3][4][5][6][7][8][9]. There are no biomechanical comparisons of these two variants.…”

“…This is because there is a variety of surgical approaches that are taken to accomplish minimally-invasive cervical discectomy [5][6][7][8][9]. The key point to note is that our approach is consistent with the essential elements of each of these surgical approaches [5][6][7][8][9]. The second specific simplification is that we modeled each of the two constituents of the AF (the ground substance and the reinforcing fibers) as well as the NP as isotropic, elastic solids.…”

“…These are anterior cervical discectomy followed by fusion (ACDF) (the most popular method) [1,2]; discectomy without fusion (DISWF) (used in a modest number of cases) [1,[3][4][5][6][7][8][9]; percutaneous nucleotomy (used in a few cases) [10]; total disc replacement (recently approved by regulatory bodies, such as the US Food and Drug Administration) [11][12][13]; and nucleus pulposus (NP) replacement [14] and intervertebral disc transplant [15] (each being an emerging option).…”

“…One is referred to as the conventional, standard, or open approach [1,3,4] while the other is a family of minimally-invasive procedures, namely, percutaneous cervical discectomy, percutaneous endoscopic cervical discectomy, percutaneous cervical laser decompression, percutaneous microcompressive endoscopic cervical discectomy microdiscectomy [5][6][7][8][9]. Arguably, the two most important driving forces for the introduction and increasing popularity of the latter techniques are to utilize a narrower surgical entry window and to reduce the amount of soft tissue that is disrupted and/or excisedin addition to the affected parts of the disccompared to the former procedure [16].…”

The purpose of this study was to determine the differences in biomechanical responses of tissues in the cervical spine when pain and other problems secondary to severe disc degeneration disease are surgically treated by conventional discectomy (CONDIS) compared to minimally-invasive discectomy (MIVDIS). A validated three-dimensional model of an intact, healthy, adult full cervical spine (C1-C7) (INT) was constructed. This model was then modified to create two models, one simulating each of the above-mentioned two techniques for discectomy of the severely degenerated C5-C6 disc. For each of these three models, we used the finite element analysis method to obtain four biomechanical parameters at various tissues in the model, under seven different physiologically relevant loadings. For each of the biomechanical parameters, the results were expressed as relative change in its value when a specified combination of simulated discectomy model and applied loading was used, with respect to the corresponding value in the intact model. We then computed the value of a composite biomechanical performance index (CBPI) for CONDIS and MIVDIS models, with this value incorporating all of the aforementioned relative changes. We found that CBPI was marginally lower for MIVDIS model. This trend is the same as that reported for the relative complications rate and outcome measures following conventional and minimally-invasive discectomies in the lumbar spine. From a healthcare perspective, one implication of our finding is that minimally-invasive cervical discectomy should be considered an attractive option provided that detailed patient selection criteria are clearly defined and strictly followed.

“…Authors have reported satisfactory clinical outcomes utilizing this minimally invasive percutaneous endoscopic technique with cervical discectomy [1]. One noted drawback to the utilization of this endoscopic technique is limited visibility, which can restrict the use of certain implants such as fusion cages and other fixation devices.…”

With minimally invasive technique becoming more popular, endoscopic operations such as arthroscopy or laparoscopy have become the standard of care in several other areas. In this study, we evaluated the 5-year followup outcomes of anterior cervical (Ahn et al. in Photomed Laser Surg 23:362-368, 2005) discectomy and interbody fusion (ACDF) performed via endoscopic approach. Sixtyseven patients who underwent anterior cervical discectomy and cage fusion performed using endoscopic technique were followed for at least 5 years. We reviewed the clinical and radiographic records of these patients. The postoperative radiographic measures accessed were the anterior intervertebral height (AIH) and the lordosis angle (LDA). Clinical outcomes were determined using the previously validated Japanese Orthopaedic Association (JOA) and the pain visual analog scale (VAS). Patients included had a minimal follow-up period of 5 years and based on the outcomes criteria (JOA, VAS), 86.6% of patients reported excellent or good results. The AIH increased on average 18.7% of the original height (p \ 0.01), and the LDA were more physiologic at final follow-up. Of the 67 cases, there was no segmental instability, and the bone fusion rate was 100%. One patient required revision open ACDF due to adjacent segment disc herniation 6 years postoperatively. There were no intraoperative complications, dysphasia or esophageal injury in this study group. It indicated endoscopic technique for ACDF can obtain satisfactory results in patients with cervical disc herniation, cervical myelopathy, or radiculopathy. Compared with a traditional approach, this technique may be associated with less morbidity while improving cosmesis and postoperative recovery. Prospective randomized control trials are needed to directly compare these two procedures.

Percutaneous Endoscopic Cervical Discectomy: Clinical Outcome and Radiographic Changes

Abstract: The high-resolution working channel endoscope allowed us to selectively remove the cervical herniated disc. The postoperative disc height reduction was observed, with no significant effect on therapeutic success. The sagittal alignment and segmental motion were well preserved.
