Cauda equina syndrome (CES) is a rare neurologic condition that is caused by compression of the cauda equina. Cauda equina consists of spinal nerves L2-L5, S1-S5 and the coccygeal nerve. The compression of these nerve roots can be caused mainly by lumbar disc herniation (45% of all causes). The diagnosis consists of two critical points: a) detailed history and physical examination and b) MRI or CT. The gold standard of the treatment of this syndrome is the surgical approach in combination with the timing of onset of symptoms...

We report the unusual case of a young patient with reoperation after annuloplasty using the Barricaid® (Intrinsic Therapeutics, Woburn, MA, USA) closure device. Our patient, a 32-year-old man underwent lumbar discectomy and annuloplasty of the level L5-S1. Five years later, the patient presented with a new onset of low-back pain radiating into the right leg. Imaging revealed loosening of the annulus repair device. The device was removed surgically and the patient was pain free thereafter. Annular closure devices such as the Barricaid system aim to improve outcome after lumbar discectomy by reducing the risk of recurrent disc herniation of the same level...

Background context Prolonged microgravity exposure is associated with localized low back pain and an elevated risk of post-flight disc herniation. Though the mechanisms by which microgravity impairs the spine are unclear, they should be foundational for developing in-flight countermeasures for maintaining astronaut spine health. Because human spine anatomy has adapted to upright posture on Earth, observations of how spaceflight affects the spine should also provide new and potentially important information on spine biomechanics that benefit the general population...

BACKGROUNDS: Although open lumbar discectomy is a gold standard surgical technique for lumbar disc herniation (LDH), surgery-induced tissue injury may actually become a source of postsurgical pain. Percutaneous endoscopic lumbar discectomy (PELD) is introduced as a minimal invasive spinal technique for LDH. The PELD has gained popularity and shown successful results. The authors report the clinical usefulness of the PELD technique in two patients with the serial multilevel LDHs. CASE PRESENTATIONS: A 32-year-old man suffered from radicular pain at the L5 dermatome due to the down migrated soft LDH at the L4-5 level...

BACKGROUND: The anterior approach to lumbar spine surgery has grown in popularity in the past few years; spinal fusion of the last 2 lumbar levels is often required. Although alternatives to bone grafting are available, including recombinant human bone morphogenetic protein 2 or bone substitutes, only cancellous autologous bone has all the required factors for bone growth. To avoid the use of bone substitutes, remote iliac crest bone harvesting remains the gold standard. However, this technique may lead to some unfavorable outcomes...
