Minimum Two-Year Follow-Up of Cases with Recurrent Disc Herniation Treated with Microdiscectomy and Posterior Dynamic Transpedicular Stabilisation

The objective of this article is to evaluate two-year clinical and radiological follow-up results for patients who were treated with microdiscectomy and posterior dynamic transpedicular stabilisation (PDTS) due to recurrent disc herniation. This article is a prospective clinical study. We conducted microdiscectomy and PDTS (using a cosmic dynamic screw-rod system) in 40 cases (23 males, 17 females) with a diagnosis of recurrent disc herniation. Mean age of included patients was 48.92 ± 12.18 years (range: 21-73 years). Patients were clinically and radiologically evaluated for follow-up for at least two years. Patients’ postoperative clinical results and radiological outcomes were evaluated during the 3rd, 12th, and 24th months after surgery. Forty patients who underwent microdiscectomy and PDTS were followed for a mean of 41 months (range: 24-63 months). Both the Oswestry and VAS scores showed significant improvements two years postoperatively in comparison to preoperative scores (p<0.01). There were no significant differences between any of the three measured radiological parameters (α, LL, IVS) after two years of follow-up (p > 0.05). New recurrent disc herniations were not observed during follow-up in any of the patients. We observed complications in two patients. Performing microdiscectomy and PDTS after recurrent disc herniation can decrease the risk of postoperative segmental instability. This approach reduces the frequency of failed back syndrome with low back pain and sciatica.

Disc Herniations

Lumbar disc surgery is performed exclusively for disc herniation. Either low back pain, or sciatica or both are common presentations depending upon the levels of compressed nerve roots. Indications for surgery and MRI needs to be carefully judged upon keeping the economic status of our patients into consideration. Open lumbar (micro) discectomy is safe and successful method for lumbar disc herniations at periphery. Results in these hundred thirteen initial cases with minimum follow up of 5 years indicate that this is not only feasible but safe in these 57 males and 56 female patients aged between 12 and 93. Redo surgeries were not that difficult in this series and were safe. There were 18 cases with Multiple and 95 single levels. Of the single levels it gradually increased as the level gradually decreased in terms of the vertebral counts. L3/4: 3 cases, L4/5: 28 cases and L5/S1 : 64 cases . There were 18 cases of more than one level discs. There were 96 (Micro) discectomies, 11 Laminotomies and 6 Laminectomies.Nepal Journal of Neuroscience 13:30-34, 2016

Decompression Procedure

Objective To present our experience in managing calcified lumbar disc herniation (cLDH) using a surgical decompression procedure. Methods Patients who had low back pain radiating to the leg, were preoperatively diagnosed with cLDH by computed tomography and/or magnetic resonance imaging, and were treated with a surgical decompression procedure were studied. Those without cLDH or who were treated with a method other than decompression were excluded. The treatment outcome was analyzed using the visual analog scale (VAS) score, Oswestry Disability Index, and modified Macnab criteria. Results Thirty-seven patients aged 60.5 ± 9.6 years were evaluated. The VAS scores were significantly decreased 1 day after surgery and remained low at the 3-month and 1-year follow-ups. The Oswestry Disability Index was also significantly lower at the 3-month and 1-year follow-ups. Ninety-four percent of patients rated the results as “excellent” or “good” according to the modified Macnab criteria at the 3-month follow-up. The patients developed few postoperative complications and no recurrence during 1 year of follow-up. Conclusion Our data suggest that the decompression approach is effective for management of cLDH at least in the short term (1 year) with respect to reducing pain and improving patient satisfaction with few complications.

OBJECTIVEThis study aimed to evaluate the clinical outcomes of percutaneous endoscopic transforaminal discectomy (PETD), microendoscopic discectomy (MED), and microdiscectomy (MD) for treatment of symptomatic lumbar disc herniation (LDH).METHODSOne hundred ninety-two patients with symptomatic LDH at L3–4 and L4–5 were included in this study. The mean (± SD) age of patients was 34.2 ± 2.6 years (range 18–62 years). The patients were divided into groups as follows: group A was treated with PETD and included 60 patients (31 men and 29 women) with a mean age of 36.2 years; group B was treated with MED and included 63 patients (32 men and 31 women) with a mean age of 33.1 years; and group C was treated with MD and included 69 patients (36 men and 33 women) with a mean age of 34.0 years. The Japanese Orthopaedic Association (JOA) scale for low-back pain (LBP), Oswestry Disability Index (ODI), creatine phosphokinase activity 3 days after surgery, and visual analog scale (VAS) scores for LBP and leg pain were used for evaluation of clinical results.RESULTSThere were no significant differences in mean preoperative JOA score, ODI score, and VAS scores for LBP and leg pain among groups A, B, and C. Incision length, duration of the operation, blood loss, creatine phosphokinase, length of hospital stay, and postoperative incision pain according to the VAS were best in the PETD group (p < 0.05). The number of seconds of intraoperative fluoroscopy was highest in the PETD group (p < 0.05), whereas there was no difference between the MED and MD groups. Three cases from the MED group and 2 cases from the MD group had an intraoperative durotomy. No CSF leakage was observed after surgery. One case from the MED group and 3 cases from the MD group had incision infections. There were no neurological deficits related to the surgeries in any of the groups. Fifty-five (91.6%), 59 (93.7%), and 62 patients (89.9%) had at least 2 years of follow-up in groups A, B, and C, respectively. At the last follow-up, JOA scores, VAS scores of LBP and leg pain, and ODI scores were significantly better than preoperative correlates in all groups. There were no differences among the 3 groups in JOA scores, JOA recovery rate, ODI scores, and VAS scores for leg pain. The VAS score for LBP was best in the PETD group (p < 0.05). No lumbar instability was observed in any group. Three cases (5.5%) in the PETD group had recurrent LDH, and 2 recurrent cases (3.4%) were confirmed in the MED group.CONCLUSIONSPETD, MED, and MD were all reliable techniques for the treatment of symptomatic LDH. With a restricted indication, PETD can result in rapid recovery and better clinical results after at least 2 years of follow-up.

OBJECTIVELumbar disc herniation (LDH) in the pediatric population is rare and exhibits unique characteristics compared with adult LDH. There are limited data regarding the safety and efficacy of minimally invasive surgery (MIS) using tubular retractors in pediatric patients with LDH. Here, the outcomes of MIS tubular microdiscectomy for the treatment of pediatric LDH are evaluated.METHODSTwelve consecutive pediatric patients with LDH were treated with MIS tubular microdiscectomy at the authors’ institution between July 2011 and October 2015. Data were gathered from retrospective chart review and from mail or electronic questionnaires. The Macnab criteria and the Oswestry Disability Index (ODI) were used for outcome measurements.RESULTSThe mean age at surgery was 17 ± 1.6 years (range 13–19 years). Seven patients were female (58%). Prior to surgical intervention, 100% of patients underwent conservative treatment, and 50% had epidural steroid injections. Preoperative low-back and leg pain, positive straight leg raise, and myotomal leg weakness were noted in 100%, 83%, and 67% of patients, respectively. The median duration of symptoms prior to surgery was 9 months (range 1–36 months). The LDH level was L5–S1 in 75% of patients and L4–5 in 25%. The mean ± SD operative time was 90 ± 21 minutes, the estimated blood loss was ≤ 25 ml in 92% of patients (maximum 50 ml), and no intraoperative or postoperative complications were noted at 30 days. The median hospital length of stay was 1 day (range 0–3 days). The median follow-up duration was 2.2 years (range 0–5.8 years). One patient experienced reherniation at 18 months after the initial operation and required a second same-level MIS tubular microdiscectomy to achieve resolution of symptoms. Of the 11 patients seen for follow-up, 10 patients (91%) reported excellent or good satisfaction according to the Macnab criteria at the last follow-up. Only 1 patient reported a fair level of satisfaction by using the same criteria. Seven patients completed an ODI evaluation at the last follow-up. For these 7 patients, the mean ODI low-back pain score was 19.7% (SEM 2.8%).CONCLUSIONSTo the authors’ knowledge, this is the longest outcomes study and the largest series of pediatric patients with LDH who were treated with MIS microdiscectomy using tubular retractors. These data suggest that MIS tubular microdiscectomy is safe and efficacious for pediatric LDH. Larger prospective cohort studies with longer follow-up are needed to better evaluate the long-term efficacy of MIS tubular microdiscectomy versus other open and MIS techniques for the treatment of pediatric LDH.

Object The goal of this study was to assess whether a stable but nonrigid nonfusion implant can stabilize the spine in degenerative diseases and also prevent instability following decompression. Instrumented spondylodesis is a recognized surgical treatment in degenerative disease of the lumbar spine. However, pain can develop at the bone graft donor site and the operative trauma can be very stressful in elderly patients, and it is suspected that there may be increased degenerative changes in the adjacent segments. In 2002, a nonrigid but rotationally stable pedicle screw and rod system was introduced, which could be used without additional fusion (referred to hereafter as the Cosmic system). Methods A total of 139 patients with degenerative disease of the lumbar spine underwent spinal stabilization with the Cosmic system without additional spondylodesis. Seventy patients had an additional decompression. The minimum follow-up was 2 years. The perioperative course, the clinical results, and the erect anteroposterior and lateral radiographs were recorded and compared with the preoperative data. The data were obtained from 6 different spine centers in Europe and documented on an Internet platform. Results The Oswestry Disability Index score improved from 48.9% to 22.5%, and the visual analog scale score decreased from 7.3 to 2.5. Lumbar lordosis did not change, nor did the adjacent disc height. Eleven patients underwent revision, 4 of them for implant failure. Of the 139 patients, 110 assessed the result as excellent, very good, or good; 24 as fair; and 5 as poor. A total of 122 patients would undergo surgery again. There were no significant differences between patients with or without an additional decompression. Conclusions The Cosmic system is a stable but nonrigid posterior nonfusion system. Implant complications are low and the clinical outcome is good. Longer follow-up is necessary to confirm the 2-year results.

A new protocol for the selected omission of transsyndesmotic fixation in Weber class C ankle fractures was prospectively evaluated in 21 consecutive patients. As proposed in a previous cadaveric study ( J. Bone Joint Surg., 71A:1548–1555, 1989), the protocol suggested that transsyndesmotic fixation was not required if (1) rigid bimalleolar fracture fixation was achieved or (2) lateral without medial fixation was obtained (i.e., with accompanying deltoid tears) if the fibular fracture was within 4.5 cm of the joint. According to this protocol, only 3 of 21 patients (14%) required transsyndesmotic fixation. Ten of the patients who did not receive transsyndesmotic fixation underwent pronation-external rotation stress radiographs in a fashion analogous to the previous cadaveric study. At 1- to 3-year follow-up, no stress (N = 10) or static view (N = 18) widening of the mortise or syndesmosis was seen in any patient, which supports (with the above guidelines) a limited, rather than routine, use of supplemental transsyndesmotic fixation. Clinical results from this prospective study seem to substantiate previously proposed biomechanical guidelines for the selected omission of transsyndesmotic fixation. Given these guidelines, transsyndesmotic fixation was unnecessary in many cases and the need can be determined before surgery by assessing the integrity of the deltoid ligament and level of the fibular fracture.

Opioid Medications

OBJECTIVE Opioid analgesics have become some of the most prescribed drugs in the world, despite the lack of long-term studies evaluating the benefits of opioid medications versus their risks associated with chronic use. In addition, long-term opioid use may be associated with worse long-term clinical outcomes. The primary objective of this study was to evaluate whether preoperative opioid use predicted inferior clinical outcomes among patients undergoing transforaminal lumbar interbody fusion (TLIF) for symptomatic lumbar degenerative disc disease. METHODS The authors of this observational study prospectively enrolled 93 patients who underwent 1-level to 2-level TLIFs in 2011–2014; the patient cohort was divided into 2 groups according to preoperative opioid use or no such use. Visual analog scale (VAS) scores for low-back pain and leg pain, Oswestry Disability Index scores, and the scores of the mental component summary (MCS) and physical component summary (PCS) on the 36-Item Short Form Health Survey were used to assess pain, disability, and health-related quality of life outcomes, respectively. The clinical scores for the 2 groups were determined preoperatively and at a 12-month follow-up examination. RESULTS In total, 60 (64.5%) patients took prescribed opioid medications preoperatively. Compared with those not taking opioids preoperatively, these patients had significantly higher VAS scores for low-back pain (p = 0.016), greater disability (p = 0.013), and lower PCS scores (p = 0.03) at the 12-month follow-up. The postoperative MCS scores were also significantly lower (p = 0.035) in the opioid-use group, but these lower scores were due to significantly lower baseline MCS scores in this group. A linear regression analysis did not detect opioid dose–related effects on leg and back pain, disability, and MCS and PCS scores, suggesting that poorer outcomes are not significantly correlated with higher opioid doses taken by the patients. CONCLUSIONS The use of opioid medications to control pain before patients underwent lumbar fusion for degenerative lumbar conditions was associated with less favorable clinical outcomes postoperatively. This is the first study that has demonstrated this association in a homogeneous cohort of patients undergoing TLIF; this association should be studied further to evaluate the conclusions of the present study.

Abstract Background: The percutaneous intervertebral foramen mirror technology is a new solution for lumbar disorders. However, like other minimally-invasive treatments for calcified lumbar discs, it is still controversial. The aim of this study was to investigate the use of the percutaneous intervertebral foramen lens technology for secondary molding of the intervertebral foramen in the treatment of calcified lumbar discs. Methods: The study included 50 patients aged (mean ± standard deviation) 49.9 ± 14.5 years, 30 (60%) females, who were diagnosed with calcified lumbar disc herniation by computed tomography and magnetic resonance imaging. Patients underwent a percutaneous endoscopic lumbar discectomy surgery in our hospital from January 1, 2017 to December 31, 2019. Demographic characteristics before the surgery and perioperative outcomes were retrospective reviewed. The treatment outcome was analyzed using the visual analog scale (VAS) score, the Oswestry Disability Index score, and modified Macnab criteria. Results: We evaluated those patients who showed significant improvement in both the VAS and ODI scores after the surgery and maintained relatively low ODI and VAS scores during subsequent follow-ups. Ninety-four percent of patients rated the results as "excellent" or "good" according to the modified Macnab criteria at the 3-month follow-up. One patient developed neck pain during the surgery, which was diagnosed as spinal hypertension syndrome, and the surgery was suspended until the patient improved. No patient had a dural leak, infection, or other related complications. Conclusions: Our results indicate that transforaminal remolding is effective in the treatment of calcified lumbar disc herniations, with few intraoperative and postoperative complications.Our results indicate that secondary reconstruction of the intervertebral foramen under visual conditions using microscopic knife is an effective method for treating calcified lumbar disc herniation, with few intraoperative and postoperative complications.

Recurrent Lumbar Disc Herniation

Abstract Purpose Recurrent lumbar disc herniation is the most common complication after discectomy. Due to the altered anatomy with the presence of scar tissue, the surgical revision of already operated patients could be a surgical challenge. Methods We describe the microsurgical revision technique step by step with the evaluation of our own clinical results in comparison with primary lumbar disc surgeries. The clinical data are based on a clinical register with 2576 recorded primary surgeries (PD) and 592 cases of revisions (RD) with 12- and 24-month follow-up (FU). The intraoperative dura lesion rates of the surgeries between 2016 and 2018 were recorded retrospectively. Data from 894 primary disc surgeries and 117 revisions were evaluated. Results The ODI and the VAS for leg and back pain improved in both groups significantly with slightly inferior outcome of the revision group. The ODI improved from 46.3 (PD) and 45.9 (RD), respectively, to 12.6 (PD) and 22.9 (RD) at the 24-month FU. The VAS dropped down as well in both group [VAS back: 47.8 (PD) and 43.9 (RD) to 19.9 and 32.2 at the 24-month FU; VAS leg: 62.9 (PD) and 65.5 (RD) to 15.6 and 26.8 at the 24-month FU]. During the primary interventions, we observed 1.5% (11/894) and during revisions 7.7% (9/117) of dura lesions. Conclusions There is no clear guideline for the surgical treatment of recurrent disc herniations. In most cases, a pure re-discectomy is sufficient and can be performed safely and effectively with the help of a microscope.
