AIMS: Lumbosacral lipomas (LSL) are congenital disorders of the terminal spinal cord region that have the potential to cause significant spinal cord dysfunction in children. They are of unknown embryogenesis with variable clinical presentation and natural history. It is unclear whether the spinal cord dysfunction reflects a primary developmental dysplasia or whether it occurs secondarily to mechanical traction (spinal cord tethering) with growth. Whilst different anatomical subtypes are recognised and classified according to radiological criteria, these subtypes correlate poorly with clinical prognosis...

BACKGROUND AND AIMS: Persistent low back pain after initially successful surgery that is not attributed to structural deficits, is called failed back surgery syndrome (FBSS). When conservative and minimal invasive therapy fail, the recommended treatment is spinal cord stimulation (SCS). Because epidural fibrosis can be a contributing factor in the majority of FBSS patients, lumbosacral epiduroscopic lysis of adhesions may be considered as a less invasive alternative treatment option. We hypothesized that the use of epiduroscopic lysis of adhesions could reduce the need for SCS...

Many spine surgeons enlist the aid of an "access surgeon" to provide anterior exposure of the lumbosacral spine. We proposed that a single, community hospital general surgery practice can successfully develop an anterior spine exposure program with acceptable clinical outcomes. One hundred and forty-three consecutive anterior exposures were performed between 2008 and 2014. Morbidity and 30-day mortality were recorded. The effects of American Society of Anesthesiologists Physical Status classification (ASA class) and number of levels exposed on length of stay (LOS) and estimated blood loss (EBL) was reported...

Phakomatosis pigmentovascularis (PPV) is a syndrome characterized by the association of a vascular nevus with a congenital pigmented lesion (epidermal nevus, nevus spilus, and dermal melanocytosis). There are different types of PPV according to the pigmentary nevus associated with the vascular malformation. Patients may present only the cutaneous condition or have systemic manifestations, among them, trauma, neurological and ophthalmological disorders. We report the case of a 1-year-old girl who had congenital glaucoma...

REVIEW
Thomas Carlstedt, Nicholas James, Mårten Risling
This mini review describes the current surgical strategy for restoring function after traumatic spinal nerve root avulsion in brachial or lumbosacral plexus injury in man. As this lesion is a spinal cord or central nervous injury functional return depends on spinal cord nerve cell growth within the central nervous system. Basic science, clinical research and human application has demonstrated good and useful motor function after ventral root avulsion followed by spinal cord reimplantation. Recently, sensory return could be demonstrated following spinal cord surgery bypassing the injured primary sensory neuron...

AIMS: Lumbar to sacral rerouting surgery can potentially allow voiding via a skin-central nervous system-bladder reflex pathway. Here, we assessed if this surgery was effective in treating neurogenic bladder dysfunction/sphincter in felines. METHODS: Eight cats underwent spinal cord transection (SCT) at thoracic level 10/11. Unilateral L7 to S1 ventral root anastomosis was performed 1 month later in six cats. Two cats served as transection-only controls. Electrical and manual stimulation of L6-S1 dermatomes, and urodynamics were performed at 3, 5, 7, and 9/10 months post transection...

PURPOSE: Chordoma is a low-grade malignant bone tumor derived from embryonic notochord remnants along the axial skeleton. About 50% of chordomas occur in the sacral vertebrae and 35% in the skull base. Most chordomas are extradural and cause extensive bone destruction. Intradural spinal tumors without bone involvement are rare. METHODS: We herein describe the clinical features of a patient with a chordoma as well as the imaging and pathological manifestations of the tumor...

RATIONALE: Hemivertebrae, which are the most frequent cause of congenital scoliosis, pose a challenge in terms of prognosis and therapy. The current gold standard treatment congenital scoliosis due to a lumbar and thoracic hemivertebra would be hemivertebra resection and short level posterior spinal fusion. Paucity literatures are reported for the treatment of hemivertebra by convex fusion with posterior hemivertebra excision. PATIENT CONCERNS: The patient was first noticed to have a spinal problem at 7 years of age...

There is mounting evidence underscoring a role for the urothelium in urinary bladder sensation. Previous functional studies have identified bladder primary afferents with mechanosensitive properties suggesting urothelial innervation and/or communication. The current study identifies a group of urothelium-innervating afferent neurons in rat, and characterizes and compares the properties of these and non-urothelial afferent neuron populations. Lumbosacral (LS) primary afferent neurons were retrogradely labeled using intraparenchymal (IPar) microinjection or intravesical (IVes) infusion of tracer into the bladder...

Patients who present with a history of cancer and the new onset of lumbosacral or peripheral neuropathy should be evaluated for the potential of metastasis. Targeted fascicular biopsy can be useful to diagnose atypical lesions within peripheral nerves in patients with major or progressive neurological deficits. In this video, the authors demonstrate the technique of targeted fascicular biopsy of the sciatic nerve in a 63-year-old man with a history of prostate cancer.
