BACKGROUND Accounting for less than 0.4% of disc herniations, intradural lumbar disc herniations (ILDHs) are a rare occurrence primarily described as a complication after lumbar spine surgery. It is speculated that the herniation may propagate intradurally from either an unrecognized dural defect after initial surgery or as a result of adhesions between the dura and posterior longitudinal ligament. This report explores the etiology, presentation, diagnostic evaluation, and treatment of ILDH along with a case report and microsurgery video. OBSERVATIONS A 67-year-old patient who 1 year earlier had undergone an L2–5 laminectomy and L2–3 decompression with no known complications presented with low back pain and radiating right leg, buttock, and groin pain for 1 month. Physical examination indicated no numbness or weakness. Magnetic resonance imaging demonstrated a large ILDH. A transforaminal interbody fusion was performed followed by a durotomy, ILDH removal, and dural closure. A ventral dural defect was found and repaired during the procedure. LESSONS The treatment for ILDH is laminectomy with dorsal durotomy. Because ILDH has rarely been described in literature, understanding its presentation is crucial for prompt identification and management.

Abstract OBJECTIVE To demonstrate the feasibility of anterior lumbar microdiscectomy in patients with recurrent, sequestered lumbar disc herniations. METHODS Between 1997 and 1999, six patients underwent a muscle-sparing “minilaparotomy” approach and subsequent microscopic anterior lumbar microdiscectomy and fragmentectomy for recurrent lumbar disc extrusions at L5–S1 (n = 4) or L4–L5 (n = 2). A contralateral distraction plug permitted ipsilateral discectomy under microscopic magnification. Effective resection of the extruded disc fragments was accomplished by opening the posterior longitudinal ligament. Interbody fusion was performed by placing cylindrical threaded titanium cages (n = 4) or threaded allograft bone dowels (n = 2). RESULTS There were no complications, and blood loss was minimal. Follow-up magnetic resonance imaging revealed complete resection of all herniated disc material. Plain x-rays revealed excellent interbody cage position. Radicular pain and neurological deficits resolved in all six patients (mean follow-up, 14 mo). CONCLUSION Anterior lumbar microdiscectomy with interbody fusion provides a viable alternative for the treatment of recurrent lumbar disc herniations. Recurrent herniated disc fragments can be removed completely under direct microscopic visualization, and interbody fusion can be performed in the same setting.

Abstract Unilateral biportal endoscopy (UBE) is a recently introduced technique that utilizes 2 portals, one for endoscopy and one as a working portal, in contrast to full endoscopy, which utilizes a single portal. The advantages are a favorable learning curve and free mobility of instruments in the operative field. UBE is successful in addressing cervical and lumbar disc herniations, lumbar stenosis, and foraminal/extraforaminal pathologies, such as herniations and foraminal stenosis. However, there is no report of UBE for a far-lateral L5S1 facet cyst. The patient was an 85-yr-old female with a left lower limb radicular pain with magnetic resonance imaging evidence of the facet cyst compressing the L5 nerve root. Conventional treatment of such a condition would either be an L5S1 fusion procedure or a standalone decompression via the Wiltse paramedian approach. Because the patient had no instability, we decided to do a standalone decompression using the UBE technique. The UBE technique has the advantages of any minimal access procedure, including small incisions, minimal tissue dissection, good magnification, and preservation of anatomic structures. A written informed consent was obtained from the patient before the procedure. The procedure was done under general anesthesia using a 30° endoscope, a radiofrequency probe, and standard lumbar spine surgery instruments. The initial landing point of the endoscope and instruments is via triangulation at the lateral border of the isthmus of L5. The postoperative clinical and radiological outcomes were satisfactory (VAS Back and Leg, 0; Oswestry disability index, 15 at 3 mo).

Study Design: Systematic review and illustrative case. Objectives: Lumbar spinal chondromas (LSCs) are rare spine tumors. The characteristics of these intraspinal lesions are not well described in the literature. The goal of this article is to describe the features of this rare spinal tumor. Methods: A PubMed and Scopus search adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was performed to include studies reporting patients with LSCs. The data gathered from this review was analyzed to characterize LSCs. Results: The search yielded 14 cases of patients with LSCs. All studies were case reports (Level V of evidence). Different characteristics of LSCs are described, including demographics, clinical findings, imaging, and treatment. Conclusions: The results of this review show that LSCs are almost exclusively seen in the extradural space and may adopt a dumbbell shape. LSCs frequently manifest in a very similar way to lumbar disc herniations; therefore, they should be considered in the differential diagnosis of sciatica, especially if magnetic resonance imaging with gadolinium shows peripheral rim enhancement of the lesion. Different degrees of improvement are usually observed after surgical treatment of these patients.

Objectives: Cerebrospinal fluid (CSF) leaks in degenerative lumbar spine surgery are common, however, delayed cerebrospinal fluid (CSF) leaks are quite rare in neurosurgical practice. Literature regarding its incidence and management is scant.Our aim was to describe the incidence & management of delayed CSF leaks after degenerative lumbar spine surgery. Material & Methods: This was a prospective study where all patients operated for lumbar disc or stenosis, who presented with the delayed CSF leak (> 1 week postoperatively) without intraoperative record of incidental durotomy were included. Data was collected about demographics, diagnosis, operative detail, postoperative course & management issues. Results: Ten out of 1128 patients developed delayed CSF leaks (0.89%). Mean age at the time of diagnosis was 52.1 ± 6.9 years with 6 (60%) males & 4 (40%) female. The most common spinal level was L5-S1 (50%). Eighty percent (n = 8) patients underwent primary surgery while 20% (n = 2) were revisions. Clinical features were headaches (80%), dizziness (70%) and altered sensorium in 20%. Mean time of the leak was 17.3 ± 2.2 days. Two patients resolved with bed rest and compression dressing while the lumbar drain was placed in 80%. Three (30%) patients of the 8 needed open repair of the dural defect. Complications of the CSF leak included wound infection in 60%, and meningitis in one (10%) patient. There were no cases of neurologic deficit. One case eventually developed infective discitis.

✓ Lumbar-disc herniations that occur beneath or far lateral to the intervertebral facet joint are increasingly recognized as a cause of spinal nerve root compression syndromes at the upper lumbar levels. Failure to diagnose and precisely localize these herniations can lead to unsuccessful surgical exploration or exploration of the incorrect interspace. If these herniations are diagnosed, they often cannot be adequately exposed through the typical midline hemilaminectomy approach. Many authors have advocated a partial or complete unilateral facetectomy to expose these herniations, which can lead to vertebral instability or contribute to continued postoperative back pain. The authors present a series of 25 patients who were diagnosed as having far lateral lumbar disc herniations and underwent paramedian microsurgical lumbar-disc excision. Twelve of these were at the L4–5 level, six at the L5–S1 level, and seven at the L3–4 level. In these cases, myelography is uniformly normal and high-quality magnetic resonance images may not be helpful. High-resolution computerized tomography (CT) appears to be the best study, but even this may be negative unless enhanced by performing CT-discography. Discography with enhanced CT is ideally suited to precisely diagnose and localize these far-lateral herniations. The paramedian muscle splitting microsurgical approach was found to be the most direct and favorable anatomical route to herniations lateral to the neural foramen. With this approach, there is no facet destruction and postoperative pain is minimal. Patients were typically discharged on the 3rd or 4th postoperative day. The clinical and radiographic characteristics of far-lateral lumbar-disc herniations are reviewed and the paramedian microsurgical approach is discussed.

Abstract Background: Dural injury is a common complication of lumbar spine surgery. Primary closure is the “gold standard.” Objective: This technical note describes a failed primary closure of a durotomy revised using an aneurysm clip. Methods: From 2005 to 2009, 5 patients underwent repair of a durotomy with the use of aneurysm clips. Resolution of the cerebrospinal fluid leak was seen in all patients. An 84-year-old woman underwent a laminectomy with an inadvertent dural tear that was primarily repaired with suture. On postoperative day 8, the patient presented with new incisional drainage. The wound was explored, and the dura had torn around the previous sutured closure. A curved aneurysm clip was used to obtain dural closure. Postoperatively, the patient’s incision remained dry. Results: Microsurgical closure with suture is the primary modality in durotomy repair. Difficulty arises when the dura is friable and multiple small tears are present. Suturing worsens the durotomy. Also, the durotomy is often caused along a bony edge with limited visualization, requiring additional bone removal to suture, therefore risking destabilization of the spine. Conclusion: We describe the application of an aneurysm clip to treat a recurrent durotomy where the standard practice of sutured closure failed. Aneurysm clips offer a quick, safe, and secure manner to close dura without risking spinal destabilization. They offer significant benefit to already torn, friable dura. Postoperatively, patients have no limitations and are therefore prevented from being exposed to additional risks associated with bed rest. Aneurysm clips are cost and clinically effective in the management of dural injuries.
