Electrical neuromodulation of spinal networks improves the control of movement of the paralyzed limbs after spinal cord injury (SCI). However, the potential of non-invasive spinal stimulation to facilitate postural trunk control during sitting in humans with SCI has not been investigated. We hypothesized that transcutaneous electrical stimulation of the lumbosacral enlargement can improve trunk posture. Eight participants with non-progressive SCI, C3-T9, AIS A or C, performed different motor tasks during sitting...

Dear Editor, Tuberous sclerosis (TS) is an autosomal dominant multisystem disease, which occurs due to genetically determined hyperplasia of ectodermal and mesodermal cells. Clinical manifestations present on the skin and in the nervous system, kidneys, heart, and other organs. Recent studies estimate the incidence of TS at 1/6000 to 1/10,000 live births, and a prevalence in the general population of approximately 1 in 20,000 (1). There are two different genetic loci responsible for TS: 9q34 (TSC1-hamartin) and 16p13...

Fixation at the lumbosacral junction continues to be a challenge for spine surgeons despite advances in spinal instrumentation techniques. The poor bone quality of the sacrum, the complex regional anatomy, and the tremendous biomechanical forces at the lumbosacral junction contribute to the high rates of instrumentation-related complications. Although many spinopelvic fixation techniques have been reported, only a few are still widely used because of the high complication rates associated with previous techniques...

In case of pelvic recurrence of colorectal cancer, reirradiation of previously irradiated patients may increase the rate of salvage radical resection. Due to the high cumulative dose, one of the main concerns is radiation-induced lumbosacral plexopathy. This report describes multiple irradiations of a lesion adjacent to the lumbosacral plexus, using a highly selective technique, which allows optimal sparing of such a critical structure. Case description A 53-year-old woman treated in 2008 for a locally advanced rectal adenocarcinoma with preoperative pelvic irradiation and concomitant chemotherapy followed by surgery had disease recurrence in 2011 and underwent a second course of pelvic radiotherapy...

The epaxial muscles produce intervertebral rotation in the transverse, vertical and axial axes. These muscles also counteract the movements induced by gravitational and inertial forces and movements produced by antagonistic muscles and the intrinsic muscles of the pelvic limb. Their fascicles are innervated by the dorsal branch of the spinal nerve, which corresponds to the metamere of its cranial insertion in the spinous process. The structure allows the function of the muscles to be predicted: those with long and parallel fibres have a shortening function, whereas the muscles with short and oblique fibres have an antigravity action...

INTRODUCTION: Due to demographic changes, growing demands, technological developments and rising healthcare costs, analysis of resources in rural and urban primary care clinics is crucial. However, data on primary care provision in rural and suburban areas are lacking. Moreover, health inequities in small island communities tend to be reduced by social homogeneity and an almost indiscernible urban-rural difference. The aim of the study was to examine the urban-suburban differences in the indications for lumbosacral spine radiographs in a public primary healthcare centre in Malta...

Lumbar epidural varices are a rare cause of radicular pain mimicking lumbar disc herniation or other cyst-like masses including sequestrated disc herniation, facet joint synovial cyst, or perineural cyst. We report a case of a 36-year-old woman presenting with lumbar radicular pain caused by a lumbar epidural varix. Lumbar MRI revealed a cystic lesion in the ventral epidural space posterior to the right L4 body. Surgery was conducted and histopathology confirmed the diagnosis of an epidural varix. Lumbar epidural varices and other lumbar cystic lesions can commonly cause radicular pain...

PURPOSE: Severe postoperative pain following spine surgery is a significant cause of morbidity, extended length of facility stay, and marked opioid usage. The erector spinae plane (ESP) block anesthetizes the dorsal rami of spinal nerves that innervate the paraspinal muscles and bony vertebra. We describe the use of low thoracic ESP blocks as part of multimodal analgesia in lumbosacral spine surgery. CLINICAL FEATURES: We performed bilateral ESP blocks at the T10 or T12 level in six cases of lumbosacral spine surgery: three lumbar decompressions, two sacral laminoplasties, and one coccygectomy...
