Therefore anxiety 9 months after baby , patients with tight hamstrings have a significantly higher risk of postoperative sagittal imbalance [30] anxiety united . Tight hamstrings are a potential cause of postoperative sagittal decompensation General Principles the operative approach is based on the analysis of the pathoanatomical features of the deformity depression bipolar . The hyperkyphosis is the result of marked structural changes in the bones and in the soft tissues of the affected area (Table 7 depression va rating . For optimal correction of the deformity these obstacles of reduction have to be assessed and addressed individually. Several questions should be answered while planning the operative strategy:) Does the curve need an anterior release? Posterior surgery alone is sufficient if the rigidity of the anterior structures is not too severe, for instance in patients before growth arrest. Structural changes in juvenile kyphosis Anterior column) wedged vertebral bodies) disc space narrowing) premature disc degeneration) contracture of the anterior longitudinal ligament Posterior column) relative overgrowth of posterior elements (broad laminae, long spinous processes)) reduced mobility of intervertebral joints) narrow interlaminar spaces Figure 9. Surgical release Structural changes to be addressed during surgery: a, b anterior release: stiffness of intervertebral disc and anterior longitudinal ligament; and c, d posterior release: overgrowth of the posterior elements. With modern third generation instrumentation systems, loss of correction after posterior surgery no longer seems to be a problem. They concluded that anterior release is indicated only if bony bridges between the vertebrae are present or in kyphosis greater than 100 degrees [31]. Instrumentation should be carried out proximally from the upper end-vertebra of the kyphosis (usually T2, T3, or T4) down to the upper lumbar spine including the first lordotic disc space (usually L1, L2, or L3). The correction principle preferred by most surgeons nowadays is cantilever correction performed using two or four rods, which results in a tension bend with posterior segmental compression. In the individual patient, it is impossible to define the optimal degree of thoracic kyphosis. The amount of correction should not exceed the ability of the adjacent mobile spinal segments to realign. The degree of hamstring tightness should be assessed and taken into consideration during planning. A kyphosis correction of more than 50 % of its initial value should be avoided as it bears the risk of imbalance or junctional kyphosis [31]. Correction of the deformity to the high "normal" kyphosis range of 40 ­ 50 degrees seems to be advisable in order to avoid postoperative imbalance [31]. They reported on 22 patients with very satisfactory subjective outcome but a significant loss of correction, as seen also by other authors [25, 35]. Therefore, they changed their technique by adding anterior release and bone grafting to achieve circumferential fusion. Because of the flexibility of the instrumentation, postoperative cast immobilization from 9 to 12 months was deemed necessary. Using this technique in 24 patients, significant loss of correction (> 10 degrees) was observed only in five patients outside the fusion area due to insufficient length of the instrumentation. Radiographically, mean kyphosis improved from 77 degrees preoperatively to 47 degrees at follow-up. Pulmonary embolus, atelectasis, and hemothorax occurred in two patients each, vascular obstruction of the duodenum, deep wound infection, and pericardial effusion in one patient each. Using modern rigid posterior double-rod instrumentation allows for immediate mobilization of the patients without a brace or cast. The rate of correction loss has diminished considerably, and in our time anterior surgery has become necessary only in extreme cases. The aims are to save spinal segments and to avoid damage to the paraspinal muscles. Posterior Release, Correction, and Fusion the goal is shortening of the posterior column to allow for extension of the spine. The posterior release encompasses the resection of:) spinous processes) ligamenta flava) upper and lower margins of the laminae) facet joints in the area of the deformity (usually four to six segments). Instrumentation and correction of the deformity follow the cantilever and posterior tension bend (compression) principle.

Metastatic tumors involving the upper cervical spine (C1 or C2) are difficult to address with an anterior approach bipolar depression 411 . Due to the wide spinal canal in this particular area of the spine depression articles , they can be treated with decompressive laminectomy dsm v depression definition , realignment of the spine and posterior segmental instrumentation extended to the occiput (Case Study 1) [25] anxiety zoella . For this surgery, the patient is placed prone on the operating table with the cervical spine in extension and mild skull traction. Patient intubation may need to be performed under endoscopic guidance due to the severe spinal instability. Following exposure of the spine, the affected vertebral body and the two adjacent discs are completely resected to the posterior longitudinal ligament. Care is taken always to work in a posterior-to-anterior direction and never towards the spinal canal. The realignment of the cervical spine is easy and mainly occurs spontaneously after the vertebrectomy is completed. The reconstruction of the vertebral body is obtained using bone cement or a special reconstruction cage and spinal fixation with anterior plate and screws is finally performed to produce a solid spinal stabilization (Case Introduction). In the cervical spine, a two or more level involvement will require additional posterior instrumentation. Tumors involving C1/C2, multilevel cervical metastases, or the cervicothoracic junction without spinal instability are better addressed from posterior as previously described [25, 29]. One or multilevel level laminectomy combined with a plate/rod fixation using lateral mass screws or possibly pedicle screws will provide spinal stabilization. Due to the wide spinal canal in this particular area of the spine, they can be treated with decompressive laminectomy, realignment of the spine and posterior segmental instrumentation extended to the occiput (Case Study 1). Thoracic Spine Solitary thoracic vertebral body metastases are best treated by anterior corpectomy and spinal reconstruction Tumors involving the thoracic spine between T7 and T12 can be easily approached through a standard thoracotomy [3, 7, 8, 18, 35]. The segmental vessels, which course in the vertebral body depressions between the intervertebral discs, are ligated and divided. The intervertebral discs are completely resected back to the posterior longitudinal ligament. The tumoral mass is progressively removed down to the posterior longitudinal ligaments with rongeurs, curettes and, if necessary, high-speed drills. Following an adequate corpectomy, the pos- Spinal Metastasis Chapter 34 989 a b c d Figure 4. Treatment of metastasis at the cervicothoracic junction a, b A 41-year-old lady with a history of breast cancer and multilevel vertebral metastases and cord compression in the cervicothoracic junction. Physical examination revealed adequate general health and a normal neurologic status. After careful intubation under endoscopic guidance, partial spinal alignment was obtained by positioning the patient on the operating table with high skull traction and neck extension (d). Cord decompression was obtained by laminectomy of C1/C2 and enlargement of the foramen magnum. Occipitocervical fixation was performed using a screw/rod system from the occiput down to C4 (e­g). The patient died 1Ѕ years after surgery with preserved neurologic conditions and free of neck pain.

Posterior transpedicular vertebrectomy is a valid alternative for tumors in the entire lumbar and thoracic spine terior longitudinal ligament typically bulges into the defect created between the intact vertebral bodies. It should be removed to allow a complete excision of all the tumor that has infiltrated into the spinal canal. The reconstruction of the vertebral body is obtained using bone cement or a special reconstruction cage. However, bone integration may be a problem in cases with postoperative radiotherapy. Spinal stabilization is completed with an anterior plate and screw system to obtain solid spinal reconstruction. Metastatic lesions localized in the upper thoracic spine are more difficult to address using an anterior approach.

Rather than dissecting and retracting the psoas posterolaterally mood disorder for teens , a psoas splitting approach is the preferred alternative for discectomy and interbody fusion depression doctor . The anterior lumbar retroperitoneal approach approaches the spine through anatomical planes depression symptoms francais . The liberation of the peritoneal sac requires a dissection of the posterior rectus sheath at the arcuate line depression or bipolar . When retracting the common iliac vein medially to expose the L4/5 disc space, the ascending lumbar vein must be controlled and ligated prior to vessel retraction. The posterior thoracolumbar approach results in considerable collateral damage to the spinal muscles, which can be minimized by mini-access surgery and use of pinpointed retractors which are intermittently released. The target level must be identified prior to surgery to avoid unnecessary and extensive detachment of back muscles. Occipital screw fixation must be accomplished in the midline between the superior nuchal and inferior nuchal line where the bone is thick enough to bury a screw. Posterior transarticular atlantoaxial screw fixation puts the vertebral artery at risk laterally and the spinal cord medially. Atlantoaxial pedicle screw fixation is an Surgical Approaches Chapter 13 369 alternative but the 2nd cervical nerve is at risk when exposing the atlantoaxial joint. Cervical pedicle screws carry a high risk of neurovascular complications and are preserved for the most experienced spine surgeons. Thoracic and lumbar pedicle screws can be placed with minimal risk with detailed anatomical knowledge. The use of a fine awl to open the cortical bone (image guided verification in the lateral and possibly anteroposterior plane), bluntly probing the pedicle and verification with a pedicle feeler, is a safe method for screw hole preparation. Sacral screws can be placed in a divergent direction at S1 and S2 as well as in a convergent direction at S1. For neuromuscular deformities with pelvic obliquity, an iliac screw provides a solid pelvic fixation.

Posterior Elements ­ Evaluate the facets depression symptoms feeling empty , the pars depression test deutsch , spinous processes anxiety young adults , pedicles depression recipes , and the lamina. Axial images are backwards; structures that you see on the left of an axial image represent structures found on the right of the patient. Look for elongation of the central canal which may be indicative of a spondylolisthesis. Look for effacement or disruption of the thecal sac by discs, osteophytes, or spondylosis, or other space-occupying lesions. Look at the lumbar discs and evaluate for tears, herniations, nerve compression, and degeneration. In addition to examining the spinal structures, evaluate and note the paraspinal muscles, multifidus muscles, iliopsoas muscles, the great vessels, and the kidneys. Develop a relationship with your radiologist, and be willing to consult with the radiologist prior to ordering radiological studies. Explain the history, and work with the radiologist to determine the best study for each patient. T2 Weighted Image Water and fat densities are bright; muscle appears intermediate in intensity.

Additional Clinical Information Note: Device information is not utilized in prior authorization determinations. Definitions Anterior Lumbar Spine Surgery: Performed by approaching the spine from the front of the body using a traditional front midline incision. Arthrodesis: A surgical procedure to eliminate motion in a joint by providing a bony fusion. The procedure is used for several specific purposes: to relieve pain; to provide stability; to overcome postural deformity resulting from neurologic deficit; and to halt advancing disease. The technique provides access to the spine along the long axis of the spine, as opposed to anterior, posterior or lateral approaches. The surgeon enters the back through a very small incision next to the tailbone and the abnormal disc is taken out. Then a bone graft is placed where the abnormal disc was and is supplemented with a large metal screw.
