Our Surgical Strategy for Adult Spine Deformity with Osteoporosis
No full textOsteoporosis is a major social problem in Japan, which is becoming a super-ageing society. Spinal deformity in the elderly causes various symptoms such as neurological deficits, pain, gastroesophageal reflux disease, etc., which impair QOL of the patients. Osteoporosis is one of major etiologies for elderly spinal deformity. At the same time, osteoporosis often causes serious problems in surgical treatment for elderly spinal deformity including instrumentation failure, proximal and distal junctional kyphosis, etc. This presentation will summarize our surgical strategy for prevention of instrument failure, including our original surgical techniques and osteoporosis treatments
Endoscopic Access to the Ventral Thoracic spine: PETD vs. Thoracoscopy
No full textSymptomatic thoracic disc herniation (TDH) is estimated to afflict between 1 in 1,000 and 1 in 1,000,000 people; affecting men more frequently than women, with the highest incidence seen at 40-50 years of age. TDH occurs at all levels of the thoracic spine but 75% of cases occur below T8, with T11-T12 being the most common site due to spinal mobility and weakness of the posterior longitudinal ligament.Manipulation of the thoracic spinal cord through the conventional posterior approach has been associated with poor outcomes. A conventional posterior approach consisting of laminectomy, cord retraction, and disc removal was historically done to treat TDH but this causes spinal cord injury and irreversible paraplegia due to cord manipulation on the relatively rigid spinal cord.The anterior approach to the spine is also intimidating to the spine surgeon due to the unique anatomy of the thoracic spine. Conventional open approaches to the thoracic spine involve a thoracotomy, rib resection, and corpectomy to view the spinal cord anteriorly. This has been associated with perioperative morbidity due to surgical site pain, difficult/painful breathing, shoulder girdle dysfunction, and wound healing problems.In order to spare the patients suffering from these postoperative iatrogenic sequelae, the author presents two different minimally invasive approach techniques; percutaneous endoscopic thoracic discectomy (PETD) vs. thoracoscopy, each applied to a different indication or thoracic pathology, to gain an enough but safe access to the ventral thoracic spinal canal through minimized surgical damages without yielding a postsurgical morbidity
Spinal Arachnoid Cyst in Children
No full textSpinal arachnoid cyst is rarely seen in children. The presenting features can be mistakenly assumed as myelitis or Guillan-Barre syndrome. Intermittent weaknesses of the leg, progressive ascending weakness of the leg, sensory disturbance, and altered physiological reflexes are the hallmark of the disease. Nabors classified the pathology of the spinal arachnoid cyst into three types: extradural without nerve root involvement; extradural with nerve root; and intradural. It is mostly located in mid- to lower thoracic. The causes and natural history of pediatric arachnoid cysts are unclear. They usually are associated with trauma, surgery, arachnoiditis, and neural tube defects. MRI is a useful diagnostic tool. We present two cases of extradural and intradural arachnoid cysts in children. The follow-up and surgical results are reviewed. The surgical therapy itself is straightforward. However, the wrong conclusion might cause a financial burden and may cause preventable sequel.
Posterolateral Endoscopic Thoracic Discectomy: Transforaminal Approach
No full textObjective: Symptomatic soft herniated thoracic disc (HTD) before the use of magnetic resonance imaging (MRI) was a rare disease with less than 1% of all spinal disc herniation. The frequency of diagnosis of thoracic disk herniation has increased with the routine use of MRI. To avoid high morbidity and complications associated with conventional approach, the authors applied posterolateral endoscopic technique.Methods: From January 2001 to December 2016, 87 patients with non-sequestrated and soft lateral or central thoracic disc herniation underwent posterolateral endoscopic thoracic discectomy (PLETD). Under local anaesthesia with intravenous sedation, we removed the herniated disc through thoracic intervertebral foramen after foraminoplasty. The enlargement of the foramen by partially cutting the lateral aspect of superior facet with a Reamer or high-speed diamond drills. Clinical outcome was measured by the Oswestry Disability Index (ODI) and the visual analogue scale.Results: Fifty-one males and thirty-six females, aged 21 to 89 years were enrolled in this study. Mean follow-up period was 10 months (1 to 56 months). The mean ODI scores improved from 53.7 before surgery to 16.9 at the final follow-up (p <0.05). Mean VAS scores improved from 7.3 before surgery to 2.1 at the final follow-up (p <0.05). One patient required conversion to an open procedure for recurred disc protrusion in 17 days. Another one patient required repeated PLETD for recurring disc in l year. Three patients experienced transient low extremity paresthesia but all improved. There were no other serious complications associated with this procedure.Conclusion: Conventional treatment of HTD is known for its high morbidity and complications, posing a challenge to physicians. This PLETD technique for symptomatic non-sequestrated and soft HTD is a safe and effective method that provides a direct route to the lesion under local anaesthesia with less morbidity.
CASE REPORT: SURGICAL MANAGEMENT OF LUMBAR COMPRESSION FRACTURE
No full textThe lumbar vertebrae are the most common site for fracture incident because of its high mobility. The spinal cord injury usually happened as a result of a direct traumatic blow to the spine causing fractured and compressed spinal cord. A 38-year-old man presented with lumbar spine’s compression fracture at L2 level. In this patient, decompression laminectomy, stabilization, and fusion were done by posterior approach. The operation was successful, according to the X-Ray and patient’s early mobilization. Pneumothorax of the right lung and pleural effusion of the left lung occurred in this patient, so consultation was made to a cardiothoracic surgeon. Chest tube and WSD insertion were performed to treat the comorbidities. Although the patient had multiple trauma that threat a patient’s life, the management was done quickly, so the problems could be solved thus saving the patient’s life. After two months follow up, the patient could already walk and do daily activities independently
Delayed Neurological Deficit after Traumatic Odontoid Fracture
No full textFractures of the odontoid process can lead to gross instability of the atlantoaxial complex and present a significant risk for a potentially catastrophic spinal cord injury. Type II odontoid fractures are the most common odontoid fractures and are unstable that may displace anteriorly or posteriorly. If left untreated, the patient may develop atlantoaxial dislocation that causes neurological deficit also progressive myelopathy.We described the surgical management of four patients with a delayed neurological deficit after odontoid fracture with a history of trauma and after triggered by traditional massage. Traction several days before operation applied to achieve reduction of atlantoaxial dislocation.Posterior instrumentation and correction of atlantoaxial dislocation were performed with interarticular screw fixation (Harm technique) in all of the patients.All of the four patients showed a reduction of the atlantoaxial dislocation and also a neurological improvement. Cervical traction followed by posterior instrumented correction may be an effective alternative to treating delayed neurological deficits after traumatic odontoid fracture.
PERCUTANEOUS EPIDURAL NEUROPLASTY (PEN) USING COMBINATION OF HYALURONIDASE AND HYPERTONIC SALINE (NaCl 3%) IN TREATING FAILED BACK SURGERY SYNDROME
No full textBackground: Following surgical treatments for low back pain, lower extremity pain or neurologic symptoms would last or recur, this is defined as failed sack surgery syndrome (FBSS). FBSS usually occurs in 5-40% of these surgical patients. The most common cause is an epidural scar adhesion. Percutaneous epidural neuroplasty is the non-mechanical treatment for this condition. Previously, the use of hyaluronidase and hypertonic saline separately is commonly used for epidurolysis but the combination of hyaluronidase and hypertonic saline 3% has not been explored.Objective: To investigate the two-year outcomes of percutaneous epidural neuroplasty using a combination of hyaluronidase and hypertonic saline 3% in patients with FBSS.Methods: Twelve patients who experience low back pain, with or without radiculopathy, who have underwent lumbar spine surgery previously were assigned to the study. Parameters, such as the visual analogue scale scores for the back (VAS-B) and legs (VAS-L), and the Oswestry disability index (ODI), were recorded and compared between pretreatment, 1 week, 1 month, 3 months, 1 year and 2 years follow-up.Results: For all 12 patients, the postoperative VAS-B, VAS-L, and ODI were significantly different from the preoperative values in all follow-up periods: 1 month, 3 months, 1 year, and 2 years.Conclusion: Based off this study group, percutaneous epidural neuroplasty using a combination of hyaluronidase and hypertonic saline 3% has a favourable outcome in the 2 years follow-u
Cervical Spine Trauma Management
No full textThe incidence of spine injury following accidents are still very high in developing countries. Many problems occur after the accident including primary intervention on the scene, transportation to the public primary hospital, the referral system, and finally, the management at the central hospital.Cervical spinal cord injuries represent 20-33% of total spinal injuries with the prevalence of the subaxial levels. In patients with a preoperative neurological deficit due to spine trauma, in case of spinal cord compression or instability, surgery is often the treatment of choice to grant a chance of neurological recovery, early mobilization, and faster return to usual daily activities compared to the conservative treatment. In the past, many authors suggested a delayed surgical treatment to reduce postoperative complications rate, but recent studies have shown that an early decompression (<72 h) may facilitate a postoperative neurological improvement probably due to the prevention of the secondary mechanisms of damage in acute SCI.In the context of the advanced management of spinal injuries, the main points of the focused assessment, the important waypoints of a full classification of the skeletal and spinal cord injury, the principles of early prioritization and decision making, the outline of the surgical strategy including indications, timing, approaches, technique and post-operative care, and the outline principles of rehabilitation. The authors in this paper try to summarize and create a guideline of management, based on experience in a regional centre
Abstract For Thoracolumbar Trauma
No full textIn both adult and pediatric populations, thoracolumbar trauma accounts for a large portion of traumatic injuries. There is a wide spectrum of injury types, including compression fractures, burst fractures, fracture-dislocations, and more. The traditional treatment for many of these has been instrumented stabilization by an “open” approach. However, as minimally invasive techniques have been developed for degenerative disorders, there has been considerable interest in bringing the same benefits of decreased blood loss, improved wound exposure, and potentially decreased operative time to the trauma population. Further, “minimally invasive” is a broad category, encompassing percutaneous pedicle screw fixation, endoscopic/thoracoscopic approaches, and anterior column reconstruction. A few authors have put forward some algorithms of selecting appropriate patients for MIS techniques. However, the majority of published data has been limited to small case series with very heterogeneous pathologies. Further studies are needed to assess minimally invasive surgery for thoracolumbar spine trauma, with respect to short- and long-term clinical outcome, fusion rates/radiographic outcome, and cost-effectiveness.
Kyphoplasty Technique for Thoraco-Lumbar Compression Fracture
No full textOsteoporotic vertebral compression fracture (VCF) is a significant cause of morbidity and mortality among elderly patients. Fractures can happen because of osteoporosis, tumours, or other conditions.In the past two decades, kyphoplasty has emerged as surgical options that play a central role in the treatment of vertebral compression fractures. Before the common use of kyphoplasty, the principal surgical option for treatment of compression fractures was decompression and fusion. However, surgical fixation frequently failed in elderly patients because of osteopenia. Kyphoplasty has expanded to include treatment of osteoporotic compression fractures, traumatic compression fractures, and metastatic compression fractures. Osteoporotic compression fractures are now the most common indication for this procedure.Kyphoplasty utilizes an inflatable balloon to create a cavity for the cement with the additional potential goals of restoring height and reducing kyphosis. Kyphoplasty is an effective treatment options for the reduction of pain associated with vertebral body compression fractures. Biomechanical studies demonstrate that kyphoplasty is initially superior for increasing vertebral body height and reducing kyphosis, but these gains are lost with repetitive loading. Complications secondary to extravasation of cement include compression of neural elements and venous embolism. These complications are rare but more common with vertebroplasty. Kyphoplasty is a safe and effective procedure for the treatment of vertebral body compression fractures.
