CONTEXT: A Kirschner wire (K-wire) is a stainless steel pin with at least one sharpened tip that is mainly used for the internal fixation of bone fractures. While some cases of K-wire dislocation and migration have been reported as complications after fracture surgery, the intraspinal migration of a K-wire is rare. Herein, we report a case in which a K-wire used for sternal fixation 7 years earlier migrated into the spinal canal. FINDINGS: A 68-year-old male suddenly sustained severe radiating pain and numbness in his left upper extremity, and walked to our hospital...

Pediatric regional anesthesia is widely used to relieve postoperative pain after abdominal surgery. Commonly used techniques of regional anesthesia include lumbar epidural and caudal block. However, the use of central neuraxial blockade has limitations. It is contraindicated in patients with clotting abnormalities, spinal dysraphism with tethered cord syndrome, meningomyelocele, and following spinal surgery with instrumentation. Ultrasound guided transversus abdominis plane block is a new method of regional anesthesia that can be used in settings where central neuraxial blockade is contraindicated...

Spinal spirocercosis due to aberrant Spirocerca lupi nematode migration is an emerging etiology for acute myelitis in dogs in Israel, causing severe, mostly nonsymmetrical hind limb paresis or paralysis, and sometimes tetraparesis or tetraparalysis. So far, incidental identification of parasites during spinal surgery or at necropsy provides the only definite diagnosis, while antemortem diagnosis of this condition has been uncertain. Specifically, antemortem diagnosis is based on the typical clinical presentation of acute, progressive, asymmetrical hind limb paresis or paralysis, with moderate to severe eosinophilic to mixed cerebrospinal fluid (CSF) pleocytosis and increased CSF protein concentration...

Anterior cervical discectomy with fusion (ACDF) is a very well-known and often-performed procedure in the practice of spine surgeons. The earliest descriptions of the technique have always been attributed to Cloward, Smith, and Robinson. However, in the French literature, this procedure was also described by others during the exact same time period (in the 1950s). At a meeting in Paris in 1955, Belgians Albert Dereymaeker and Joseph Cyriel Mulier, a neurosurgeon and an orthopedic surgeon, respectively, described the technique that involved an anterior cervical discectomy and the placement of an iliac crest graft in the intervertebral disc space...

Factors related to the onset and progression of lumbar spinal stenosis (LSS) have not yet been identified. Diffuse idiopathic skeletal hyperostosis (DISH) increases mechanical loading on the non-fused lumbar levels and may therefore lead to LSS. This cross-sectional study aimed to identify associations between LSS and DISH. This study included 2363 consecutive patients undergoing surgery for LSS and 787 general inhabitants without symptoms of LSS as participants of the population-based cohort study, Research on Osteoarthritis/Osteoporosis Against Disability...

The authors describe a case of pneumocephalus following epidural anaesthesia for total knee arthroplasty. Multiple attempts in locating the epidural space for the anaesthesia and the use of loss of resistance to air (LORA) technique were identified as the source of air entry. Supportive management was given including high flow oxygenation therapy and spontaneous reabsorption of air was noted five days after surgery. The presence of pneumocephalus should be kept in mind if patient develops neurological complications postoperatively following epidural anaesthesia...

BACKGROUND: Thymic carcinoid with spinal metastasis is an extremely rare entity. Clinically, the tumor presents either by its endocrine manifestations or by mechanical compression of surrounding structures. However, no previous studies reported a case with neck pain, and neurological deficit as initial presentation of an atypical thymic carcinoid. METHOD: A 56-year-old non-smoking man presented with 12-month history of intermittent neck pain and 1-month history of progressive numbness and weakness of the right upper limb...

BACKGROUND: Epidural fibrosis is a challenging topic in spinal surgery. This phenomenon constitutes one of the the main reasons behind "post-laminectomy syndrome" or "failed-back surgery syndrome", which leads to persistent back and leg pain in association with compression and/or stretching the nerve root or the dura. The exact mechanism of action in epidural fibrosis is complex and remains uncertain. Excessive deposition of collagen, fibronectin, and dermatan sulfate known as "extracellular matrix", and decrease of tissue cellularity results in epidural fibrosis...

Intracranial hemorrhage is a rare complication of spinal surgery. Case 1 was a 58-year-old man who underwent cervical laminoplasty. No apparent iatrogenic dural rupture or cerebrospinal fluid leakage was observed. An hour after the surgery, the patient had convulsions and became restless thereafter. CT revealed an intracranial SAH. The patient recovered normal consciousness the next morning. Case 2 was a 68-year-old woman who underwent cervical laminoplasty without postoperative CSF leakage. Six days after the surgery, the patient continued to complain of nausea and headache...

BACKGROUND Spinal burst fractures are pathologies that occur in spinal injuries and cause significant mortality and morbidity as a result. Burst fractures in spinal cord injuries can result in rapid and significant oxidative stress. In addition to the primary injury in severe spinal cord injuries, subsequent secondary lesions are mainly due to inflammatory cascade activation and excessive production of free radicals. This study evaluated oxidative stress and antioxidant enzyme levels in burst fractures. MATERIAL AND METHODS Twenty patients with burst fractures were diagnosed and underwent surgery and 20 healthy control subjects were included in the study...

BACKGROUND: Neuropathic pain is an intractable and complex disease. Recent studies have shown a close relationship between endoplasmic reticulum (ER) stress and neuropathic pain. Here, we investigated the effect of α-asarone, an ER stress inhibitor, on chronic constriction injury (CCI)-induced neuropathic pain. METHODS: Two parts were included in this study. In part 1, rats were assigned to 7 groups: the sham group, the sham + α-asarone 20 mg/kg group, the CCI group, the CCI + vehicle group, the CCI + α-asarone 5 mg/kg group, the CCI + α-asarone 10 mg/kg group, and the CCI + α-asarone 20 mg/kg group...

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...

BACKGROUND: Although recent trials provided level I evidence for the most common degenerative lumbar spinal disorders, treatment still varies widely. Thus, the Indications in Spinal Surgery (INDIANA) survey explores whether decision-making is influenced by specialty or personal emotional involvement of the treating specialist. METHOD: Nationwide, neurosurgeons and orthopedic surgeons specialized in spine surgery were asked to answer an Internet-based questionnaire with typical clinical patient cases of lumbar disc herniation (DH), lumbar spinal stenosis (SS), and lumbar degenerative spondylolisthesis (SL)...

Superior mesenteric artery (SMA) syndrome often occurs in the setting of rapid weight loss and scoliosis corrective spinal surgery. A reduction of fat around the third part of the duodenum can predispose the duodenum to compression and obstruction by the SMA as it emerges from the abdominal aorta. In this report, we describe this underdiagnosed condition in a previously healthy young female presenting with progressive post-prandial emesis, non-specific abdominal pain, and weight loss. A critical review of this disease process is explored to highlight pathology, imaging characteristics, and essential alternative diagnostic considerations...
