Prolonged airway obstruction after posterior occipitocervical fusion: a case report and literature review.

Adv Orthop. 2011;2011:791923

Authors: Morita M, Nobuta M, Naruse H, Nakamura H

Abstract
The purpose of this paper was to inform the reader that prolonged upper airway obstruction after posterior cervical spine surgery is a possible complication for patients with metastatic tumor of upper cervical spine. A 49-year-old man presented severe neck pain during posture changes due to metastatic spinal tumor of C2. Occipitocervical fusion following removal of the posterior arch of C1 and laminectomy of C2 via the single posterior approach was performed 2 weeks after radiation therapy. After the surgery, life-threatening airway obstruction due to pharyngeal oedema occurred immediately after extubation that required emergency tracheostomy. The airway obstruction did not improve well during the patient’s postoperative course. Once pharyngeal oedema occurs in patients with metastatic tumor of upper cervical spine who undergo posterior cervical spine surgery following radiation therapy to the neck, the pharyngeal oedema may be constant for a long period of time.

Cannabidiol-treated Rats Exhibited Higher Motor Score After Cryogenic Spinal Cord Injury.

Neurotox Res. 2011 Sep 14;

Authors: Kwiatkoski M, Guimarães FS, Del-Bel E

Abstract
Cannabidiol (CBD), a non-psychoactive constituent of cannabis, has been reported to induce neuroprotective effects in several experimental models of brain injury. We aimed at investigating whether this drug could also improve locomotor recovery of rats submitted to spinal cord cryoinjury. Rats were distributed into five experimental groups. Animals were submitted to laminectomy in vertebral segment T10 followed or not by application of liquid nitrogen for 5 s into the spinal cord at the same level to cause cryoinjury. The animals received injections of vehicle or CBD (20 mg/kg) immediately before, 3 h after and daily for 6 days after surgery. The Basso, Beattie, and Bresnahan motor evaluation test was used to assess motor function post-lesion one day before surgery and on the first, third, and seventh postoperative days. The extent of injury was evaluated by hematoxylin-eosin histology and FosB expression. Cryogenic lesion of the spinal cord resulted in a significant motor deficit. Cannabidiol-treated rats exhibited a higher Basso, Beattie, and Bresnahan locomotor score at the end of the first week after spinal cord injury: lesion + vehicle, day 1: zero, day 7: four, and lesion + Cannabidiol 20 mg/kg, day 1: zero, day 7: seven. Moreover, at this moment there was a significant reduction in the extent of tissue injury and FosB expression in the ventral horn of the spinal cord. The present study confirmed that application of liquid nitrogen to the spinal cord induces reproducible and quantifiable spinal cord injury associated with locomotor function impairments. Cannabidiol improved locomotor functional recovery and reduced injury extent, suggesting that it could be useful in the treatment of spinal cord lesions.

Posterior multilevel vertebral osteotomy for severe and rigid idiopathic and nonidiopathic kyphoscoliosis: a further experience with minimum two-year follow-up.

Spine (Phila Pa 1976). 2011 Jun 15;36(14):1146-53

Authors: Modi HN, Suh SW, Hong JY, Yang JH

Abstract
STUDY DESIGN: Prospective randomized study.
OBJECTIVE: To evaluate the clinica! and radiologic outcome of posterior multilevel vertebral osteotomy (PMVO) in patients with severe kyphoscoliosis.
SUMMARY OF BACKGROUND DATA: Authors have developed and reported results of PMVO for correction of neuromuscular scoliosis. PMVO has advantages such as, posterior-only procedure which avoids risk to pulmonary complications and gives satisfactory correction. However, its effect in correcting severe scoliosis in presence of rigid kyphosis has not been reported.
METHODS: Thirteen patients (7 idiopathic, 4 cerebral palsy, and 2 congenital scoliosis) with severe and rigid kyphoscoliosis were operated by posterior-only correction with pedicle screw fixation using PMVO. As per pathology, and associated severity of kyphosis little modification in the original technique was applied while correction and osteotomy. Neuromonitoring was applied in all patients during operation. The radiologic and clinical results were evaluated with an average follow-up of 42.9±11 months. All postoperative complications were also noted during the follow-up period.
RESULTS: Average number of osteotomy was 4.2±0.8 (range, 3-5). Average preoperative Cobb angle, pelvic obliquity, thoracic kyphosis, and lumbar lordosis were 99.2°±29.6°, 8.6°±9°, 73.6°±56.9°, and -47.2°±63.2°, respectively, which improved after surgery to 44.7°±12.3°, 2.8°±2.9°, 45.3°±15.9°, and -47.7°±12.2°. All corrections were maintained at final follow-up. A 54.3% correction was achieved in coronal plane; and, full correction was achieved in sagital plane as thoracic kyphosis was restored within normal range. Average blood loss and operative time was 3015±1213 mL and 6.01±1.09 hours, respectively. Three patients had postoperative respiratory complications; 2 had hemothorax and 1 had atelectasis; none had follow-up consequences. All pulmonary complications were due to associated thoracoplasty during which pleura was ruptured intraoperatively. Two patients had complication related with the implants; 1 screw breakage and other screw prominence. There was no neurologic injury intraoperatively on motor-evoked po- tentials (MEP) or clinically after surgery.
CONCLUSION: PMVO exhibited satisfactory clinical and radiologic results in patients with severe and rigid scoliosis associated with hyperkyphosis at minimum 2-year follow-up. It can be safely applied with modifications in original technique for complex congenital scoliosis with multilevel hemi or block vertebrae and idiopathic/nonidiopathic spinal deformities.

Intramedullary tumors in children.

J Pediatr Neurosci. 2011 Oct;6(Suppl 1):S86-90

Authors: Chatterjee S, Chatterjee U

Abstract
Intramedullary tumors of the spinal cord account for 35-40% of intraspinal tumors in children. The biological behavior of these tumors is of slow progression, and hence aggressive surgery has been advocated. Surgical adjuncts include use of intraoperative neurophysiological monitoring, preoperative ultrasound, microsurgical techniques and ultrasonic suction devices. Osteoplastic laminoplasty approaches avoid post-laminectomy deformities in younger children. Postoperative radiotherapy and more recently chemotherapy regimes have been proposed for incompletely resected tumors.

Hemiparesis caused by cervical spontaneous spinal epidural hematoma: a report of 3 cases.

Adv Orthop. 2011;2011:516382

Authors: Nakanishi K, Nakano N, Uchiyama T, Kato A

Abstract
We report three cases of spontaneous spinal epidural hematoma (SSEH) with hemiparesis. The first patient was a 73-year-old woman who presented with left hemiparesis, neck pain, and left shoulder pain. A cervical MRI scan revealed a left posterolateral epidural hematoma at the C3-C6 level. The condition of the patient improved after laminectomy and evacuation of the epidural hematoma. The second patient was a 62-year-old man who presented with right hemiparesis and neck pain. A cervical MRI scan revealed a right posterolateral dominant epidural hematoma at the C6-T1 level. The condition of the patient improved after laminectomy and evacuation of the epidural hematoma. The third patient was a 60-year-old woman who presented with left hemiparesis and neck pain. A cervical MRI scan revealed a left posterolateral epidural hematoma at the C2-C4 level. The condition of the patient improved with conservative treatment. The classical clinical presentation of SSEH is acute onset of severe irradiating back pain followed by progression to paralysis, whereas SSEH with hemiparesis is less common. Our cases suggest that acute cervical spinal epidural hematoma should be considered as a differential diagnosis in patients presenting with clinical symptoms of sudden neck pain and radicular pain with progression to hemiparesis.

Risk factors for immediate postoperative complications and mortality following spine surgery: a study of 3475 patients from the National Surgical Quality Improvement Program.

J Bone Joint Surg Am. 2011 Sep 7;93(17):1577-82

Authors: Schoenfeld AJ, Ochoa LM, Bader JO, Belmont PJ

Abstract
BACKGROUND: This investigation sought to identify risk factors for immediate postoperative morbidity and mortality among a large series of patients undergoing spine surgery who were prospectively entered into a national registry.
METHODS: The database of the National Surgical Quality Improvement Program was queried to identify all patients undergoing spine surgery in the years 2005 to 2008. Demographic data, comorbidities, medical history, body-mass index, and the type of procedure performed were obtained for all patients. Postoperative complications and mortality within thirty days after the spinal procedure were also documented. The chi-square test and univariate and multivariate logistic regression analyses were used to evaluate the effect of individual risk factors on mortality, as well as the probability of the development of complications.
RESULTS: From 2005 to 2008, 3475 patients undergoing spine surgery were registered in the database. The average age of patients was 55.5 years (range, sixteen to ninety years), and 54% of the cohort were men. Ten patients (0.3%) died after surgery, and there were 407 complications in 263 patients (7.6%). Increased patient age and contaminated or infected wounds were identified as independent predictors of mortality. Increased patient age, cardiac disease, preoperative neurologic abnormalities, prior wound infection, corticosteroid use, history of sepsis, American Society of Anesthesiologists classification of >2, and prolonged operative times were independent predictors for the development of one or more complications.
CONCLUSIONS: Patient age, female sex, longer procedural times, and several types of medical comorbidities influenced the risk of postoperative complications or mortality. This information enhances estimates of morbidity and mortality following spine surgery and may improve patient selection for spine surgery as well as preoperative discussions related to the risks of spine surgery.

Endometrial stromal sarcoma metastasis to the lumbar spine and sphenoid bone.

Rare Tumors. 2011 Jul 11;3(3):e27

Authors: Huang MI, Debernardo RL, Rodgers M, Hart DJ

Abstract
Endometrial stromal sarcoma (ESS) is typically associated with metastasis to the abdomen, pelvis, and lung. We found three case reports of ESS metastasis to the bone (two to the thoracic spine, and one to the parietal bone). Our objective is to review the literature on ESS spinal and intracranial metastases and, report the first case of ESS metastatic to the lumbar paraspinal region and sphenoid bone. A 53-year-old female with ESS status-post radiation, chemotherapy, and pelvic exenteration surgery presented with right hip weakness, back pain, and radicular leg pain that were explained by chemotherapy-induced neuropathy, radiation-induced lumbosacral plexopathy, and femoral nerve and obturator nerve injury during pelvic exenteration surgery. During routine positron emission tomography, we found metastasis to the L3 lumbar spinal region. L3 laminectomy and subtotal resection of the mass was performed with tumor residual in the neuroforamina and pedicles. One month later, magnetic resonance imaging (MRI) performed for persistent headaches revealed a large lesion in the sphenoid bone that was biopsied transsphenoidally with the same diagnosis, but no further surgery was performed. She is intolerant of chemotherapy and currently undergoing whole brain radiation. Delay in the diagnosis and management of lumbar paraspinal and sphenoid bone metastasis of ESS likely occurred because of the uniqueness of the location and aggressiveness of ESS metastasis. Health care providers should be aware of potentially aggressive metastasis of ESS to bone, in particular the unusual locations of the lumbar paraspinal region and sphenoid bone.

Cervical laminoplasty for multilevel cervical myelopathy.

Adv Orthop. 2011;2011:241729

Authors: Sayana MK, Jamil H, Poynton A

Abstract
Cervical spondylotic myelopathy can result from degenerative cervical spondylosis, herniated disk material, osteophytes, redundant ligamentum flavum, or ossification of the posterior longitudinal ligament. Surgical intervention for multi-level myelopathy aims to decompress the spinal cord and maintain stability of the cervical spine. Laminoplasty was major surgical advancement as laminectomy resulted in kyphosis and unsatisfactory outcomes. Hirabayashi popularised the expansive open door laminoplasty which was later modified several surgeons. Laminoplasty has changed the way surgeons approach multilevel cervical spondylotic myelopathy.
