Objective: To investigate the early clinical effects of transforaminal endoscopic spine system (TESSYS) for the treatment of bilateral lumbar disc herniation in single segment.
Methods: The clinical data of 38 patients with single-segment bilateral lumbar disc herniation treated by TESSYS technique from February 2016 to February 2018 were retrospectively analyzed. There were 26 males and 12 females, aged from 30 to 55 years old with an average of(35.2±6.4) years, 6 cases of L₃,₄, 22 cases of L₄,₅, and 10 cases of L₅S₁1. Using the intervertebral foramen endoscope produced by Joimax GmbH, Germany, under local anesthesia, bilateral puncture to the outside of the intervertebral foramen of the diseased segment, four-stage dilatation catheter to complete the progressive enlargement of the intervertebral foramen, and the ring saw progressively enlarge the intervertebral foramen. The bilateral foramen was placed and the herniated nucleus was removed until the nerve root was completely released. Postoperatively, the patients were reviewed on regular outpatient visits and telephone follow-ups. Visual analogue scale (VAS) and Oswestry Disability Index (ODI) were compared before operation and after operation at 1, 3, 6, 12 months respectively. At the final follow-up, according to modified MacNab criteria to evaluate the clinical effect.
Results: Thirty-six patients underwent successful surgery and were followed up for more than 12 months. The ODI score and VAS score of the lower extremities pain at 1, 3, 6, 12 months after operation were obviously improved (<0.05), there was significant difference between 1, 3 months and 6, 12 months after operation(<0.05), there was no significant difference between 1 and 3 months, between 6 and 12 months after operation (>0.05). At the final follow-up, according to MacNab criteria, 14 cases got excellent results, 16 good, 4 fair, 2 poor.
Conclusions: Using TESSYS technique to remove the bilateral herniated nucleus from single segment can fully decompress for the nerve root, and can be effectively applied to patients with single-segment bilateral lumbar disc herniation.

CT-3D MERGE fusion imaging improves image quality compared with CT and 3D MERGE in patients with lumbar disc herniation.

Background: CT-routine MRI fusion imaging has recently become available to evaluate spinal anatomy before surgery. Due to the 3-5 mm slice thickness and non-isotropic of routine MRI sequence, the CT-routine MRI fusion imaging is not good. The MRI multiple recalled gradient echo (MERGE) sequence is potentially useful in diagnosis of lumbar degeneration disease due to the better nerve roots visualization, 1 mm slice thickness and its isotropy.

Article Synopsis
- The study evaluates the safety and effectiveness of a higher-voltage long-duration pulsed radiofrequency (HL-PRF) treatment for managing zoster-associated pain (ZAP) compared to standard treatment.
- Patients in Group A received gradually increased voltage up to 100 V, while Group B maintained a steady 65 V throughout.
- Results focused on pain levels, emotional well-being, and quality of life over 12 weeks, with an aim to address high recurrence rates associated with the existing methods.

Intervertebral disc disease is the most common spinal cord-related disease in dogs, caused by disc material protrusion or extrusion that compresses the spinal cord, leading to clinical symptoms. Diagnosis involves identifying radiographic signs such as intervertebral disc space narrowing, increased opacity of the intervertebral foramen, spondylosis deformans, and magnetic resonance imaging findings like spinal cord compression and lesions, alongside clinical symptoms and neurological examination findings. Intervertebral disc space narrowing on radiographs is the most common finding in intervertebral disc extrusion.

Article Synopsis
- Discogenic chronic low back pain (cLBP) and radiculopathy are common and disabling, with traditional treatments often leading to further complications or degeneration of spinal discs.
- A new treatment strategy focuses on diagnosing and treating annulus fibrosus tears by using fibrin to seal these injuries and promote tissue growth, potentially offering a safer and more effective alternative.
- This method was tested in a retrospective cohort study involving patients who had not found relief from multiple prior treatments for cLBP lasting over six months, utilizing MRI for diagnosis.

Importance: In veterinary orthopedics, addressing foramen stenosis in the L7-S1 region in dogs presents significant challenges due to limited access and visualization with conventional surgical techniques.
Objective: This study aims to evaluate endoscopic foraminotomy through the iliac window, using three-dimensionally (3D) printing guide based on the preoperative plan, in cadaveric dogs.
Methods: Trans-iliac foraminotomies were performed on each side of five canine cadavers using and individualized 3D printing guide.
