Intraregional differences of perioperative management strategy for lumbar disc herniation: is the Devil really in the details?

Enhancing treatment of lumbar disc herniation with Erxian decoction and auricular acupoint pressure: A randomized controlled trial

OBJECTIVE

The incidence of lumbar disc herniation (LDH) is on the rise annually, with an emerging trend of affecting younger age groups. This study aims to investigate the clinical effectiveness of combining Erxian decoction with auricular acupoint pressure therapy in treating LDH. Our objective is to furnish evidence supporting the incorporation of traditional Chinese medicine (TCM) rehabilitation techniques in clinical settings.

METHODS

This randomized controlled trial enrolled 102 patients diagnosed with LDH and allocated them into Control and Intervention groups. The Control group underwent a 2-week rehabilitation regimen, whereas the Intervention group received an augmented treatment comprising Erxian decoction along with auricular acupoint pressure therapy based on the Control group. Main outcome measures included 3 scales - visual analog scale (VAS), Japanese Orthopedic Association (JOA), and Oswestry Disability Index - as well as 3 inflammatory markers: C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α). Additionally, pressure pain threshold and pain tolerance threshold values were evaluated. Participants were assessed at baseline, on 14-day, and on 28-day posttreatment.

RESULTS

After 2 weeks of treatment, both the Control and Intervention groups exhibited significant improvements in the VAS, JOA, ODI, CRP, IL-6, TNF-α, pressure pain threshold, and pain tolerance threshold (P < .05). These improvements persisted at the 28-day in the VAS, JOA, and ODI scores (P < .05). On 14-day, the Intervention group showed significantly better outcomes compared to the Control group in terms of the VAS, JOA, ODI, CRP, TNF-α, and pressure pain threshold (P < .05).

CONCLUSION

Compared to conventional rehabilitation therapy, the combination of Erxian decoction and auricular acupoint pressure therapy demonstrates clear benefits in alleviating symptoms in patients with LDH. This approach offers fresh perspectives and substantiates evidence for future treatment strategies in managing LDH.

Effectiveness of Lumbosacral Orthosis After Discectomy for Lumbar Disk Herniation: A Prospective Comparative Study

STUDY DESIGN

A prospective comparative study.

OBJECTIVE

To investigate the benefits of postoperative application of lumbosacral orthosis after single-level discectomy for lumbar disk herniation (LDH).

SUMMARY OF BACKGROUND DATA

Although many surgeons use postoperative lumbosacral orthosis for patients with LDH, there is no clear evidence to support or deny its effectiveness.

MATERIALS AND METHODS

Ninety-nine consecutive patients who underwent the microscopic discectomy were included. They were divided into two groups: orthosis group and nonorthosis group, before surgery. The recurrence rate and reoperation rate were compared between the two groups at four-week, six-month, and one-year follow-up. Japanese Orthopaedic Association Score for lumbar spine (L-JOA score) at two-week and one-year follow-up, lower extremities and low back pain's visual analog scale (VAS) and Oswestry Disability Index (ODI) at six-month and one-year follow-up were compared.

RESULTS

Forty-two patients in the orthosis group and 39 patients in the nonorthosis group were followed up for at least one-year after surgery. Recurrence occurred in three patients (7.1%) in the orthosis group and six (15.4%) in the nonorthosis group within one-year. Two patients (4.8%) in the orthosis group and two patients (5.1%) in the nonorthosis group underwent reoperation. There were no significant intergroup differences in the recurrence rate and in the reoperation rate. No significant difference was also observed between the two groups in L-JOA score, ODI, VAS of low back pain, and leg pain at one-year after surgery. Furthermore, at any other follow-up period, no significant differences were observed between the two groups in recurrence rate, reoperation rate, L-JOA score, VAS of low back/leg pain, or ODI.

CONCLUSIONS

The use of a postoperative orthosis did not reduce recurrence or reoperation rates, nor did it improve postoperative clinical symptoms. The routine use of an orthosis may not be necessary after single-level lumbar discectomy.

Survey of lumbar discectomy practices: 10 years in the making

Background

Lumbar discectomy is a common spinal procedure. The purpose of this survey is to ascertain neurosurgeons' practices in the surgical management of one-level lumbar discectomies in the Canadian adult population and to determine changes over a 10-year period.

Methods

One-page questionnaire distributed electronically to neurosurgeons in Canada and results were compared with similarly completed survey from 2007.

Results

A total of 109 completed surveys were returned representing 43.8% response rate. This is compared to 112 completed surveys in 2007 reaching 64.4% response rate. Statistically significant differences between the two points in time were noted. There was an increase in spine fellowship training [26 (33.3%) 2017 vs. 15 (15.3%) 2007 (P=0.007)], use of pre-operative magnetic resonance imaging (MRI) [65 (83.3%) 2017 vs. 27 (27.6%) 2007] (P<0.001), use of intramuscular injection [58 (74.4%) 2017 vs. 43 (43.9%) 2007 (P<0.001)], use of both microscope and loupes [20 (25.6%) 2017 vs. 3 (3.1%) 2007 (P<0.001)], use of tubular retraction [26 (33.3%) 2017 vs. 12 (12.2%) 2007 (P=0.001)], use of fibrin glue for a durotomy [72 (92.3%) 2017 vs. 75 (76.5%) 2007 (P=0.007)]. There was an increased rate of same-day discharge in 2017 [46 (59.0%) vs. 18 (18.4%) 2007 (P<0.001)], and quicker return to work [62.8% in 6 weeks or less vs. 39.7% (P=0.003)]. No statistical differences were noted with pre-incision localization, pre-op antibiotics, pre-incision local anesthetic use, use of fat graft or epidural steroids. In either survey the majority would not perform lumbar discectomy on a patient whose primary complaint is back pain.

Conclusions

Our survey identified changes in practice patterns amongst Canadian neurosurgeons with respect to performing one-level lumbar discectomy over the past 10 years. These changes include increased preference for minimally invasive surgical technique, same-day discharge and sooner return to work. Randomized trials would be helpful to provide evidence regarding which practices are associated with better outcomes.

Perioperative care for lumbar microdiscectomy: a survey of Australasian neurosurgeons

Background

Lumbar microdiscectomy is the most commonly performed spine surgery procedure. Over time it has evolved to a minimally invasive procedure. Traditionally patients were advised to restrict activity following lumbar spine surgery. However, post-operative instructions are heterogeneous. The purpose of this report is to assess, by survey, the perioperative care practices of Australasian neurosurgeons in the minimally invasive era.

Methods

A survey was conducted by email invitation sent to all full members of the Neurosurgical Society of Australasia (NSA). This consisted of 11 multi-choice questions relating to operative indications, technique, and post-operative instructions for lumbar microdiscectomy answered by an electronically distributed anonymized online survey.

Results

The survey was sent to all Australasian Neurosurgeons. In total, 68 complete responses were received (28.9%). Most surgeons reported they would consider a period of either 4 to 8 weeks (42.7%) or 8 to 12 weeks (32.4%) as the minimum duration of radicular pain adequate to offer surgery. Unilateral muscle dissection with unilateral discectomy was practiced by 76.5%. Operative microscopy was the most commonly employed method of magnification (76.5%). The majority (55.9%) always refer patients to undergo inpatient physiotherapy. Sitting restrictions were advised by 38.3%. Lifting restrictions were advised by 83.8%.

Conclusions

Australasian neurosurgical lumbar microdiscectomy perioperative care practices are generally consistent with international practices and demonstrate a similar degree of heterogeneity. Recommendation of post-operative activity restrictions by Australasian neurosurgeons is still common. This suggests a role for the investigation of the necessity of such restrictions in the era of minimally invasive spine surgery.

Usefulness of corset adoption after single-level lumbar discectomy: a randomized controlled trial

OBJECTIVE In this paper, the authors sought to verify whether corset adoption could improve the short-term and midterm outcome scores of patients after single-level lumbar discectomy. METHODS A monocentric, randomized controlled trial of 54 consecutive patients who underwent single-level lumbar discectomy at the authors' institution was performed from September 2014 to August 2015. Patients were randomly assigned to use or not use a lumbar corset in the upright position. Patients with previous interventions for disc herniation or with concomitant canal or foraminal stenosis were excluded. The visual analog scale, Oswestry Disability Index, and Roland Morris Disability Questionnaire were used to compare groups at the 1- and 6-month follow-up time points. RESULTS No significant differences between the 2 groups were reported at either time point for any given outcome irrespective of the scale used. CONCLUSIONS Corset adoption does not improve the short-term and midterm outcomes of patients after single-level lumbar discectomy.
