However, because the posterior femoral cutaneous nerve runs parallel to the sciatic nerve in the gluteal region, sensory block is rarely achieved via the anterior approach. Sciatic nerve block can be performed using the anterior or posterior approach in patients undergoing surgery for malleolar fracture.

When scanning poster- iorly, transversus abdominis tailed off and turned into aponeurosis. 1 Posterior approach of transversus abdominis plane (TAP) block. Posterior approach located in the end of transversus abdominis plane where TAP transmigrate into aponeurosis. The injection site is at the TAP between internal oblique and transversus abdominis posterior to the midaxillary line and near the aponeurosis. TA: transversus abdominis. (6) time to the first mobilization.

The landmarks for the posterior approach are:. The line drawn between the bilateral posterior superior iliac spine usually pro- jects to the disc level of L4–L5 ( Fig. Surgical anatomy of the posterior thoracolumbar approach.

These approaches are obvi- ously technically more demanding than a posterior approach and are restricted to the mid thoracic to upper lumbar levels. [75] even though they reported a higher intraoperative blood loss in the thoracoscopic group. During the first year, the thoracoscopic approach was found to cause fewer declines in the vital capacity compared to the open anterior approach..

The surgeon must proactively consider potential extensions of the approach and must be familiar with this anatomy.. Image intensifier or radio- graphic verification of the correct level is an abso- lute must. Wrong level surgery is one of the most frequent complications. The anteromedial ap- proach to the cervical spine approaches the anteri- or column through anatomical planes. The posterior approach to the cervical spine can be associated with heavy bleed- ing.

The posterior approach involves excision of the posterior elements, which allows the section of the anulus fibrosus and the posterior longitudinal ligament, careful hemostasis of the epidu- ral venous plexus and posterior stabilization.

Placement of segmental instrumentation for provisional stabilization prior to completing the osteotomy can help to reduce the risk of uncontrolled translation of the spine with corresponding neurologic injury.. or through a sequential or simultaneous anterior and posterior approach . The ultimate surgical approach selected depends on the location of the hemivertebra, its type, whether it is segmented or not, and famil- iarity of the surgeon with the technique.

The bisegmental, two-level posterior approach (short segmental stabilization) is the “working horse” of the posterior techniques that allows a secure fixation of the pedicle screws in the intact vertebra one level above and below the fracture ( Fig. Fredrickson et al.

The choice of the surgical approach, i.e., posterior, anterior or combined anterior and posterior, depends on:. The posterior approach addresses the deformity by fixing rods to the posterior structures of the spine, i.e., the pedicles, the transverse processes, or the laminae ( Fig. This approach necessitates detachment of the posterior paraspinal mus- cles. Harrington introduced the first instrumentation for posterior scoliosis correction in the 1960s [85].

“working horse” of the posterior approach tech- nique that allows for fracture reduction and stable. Key articles introduce landmark papers which had a substantial impact on our current understanding of the pathology, diagnosis or non-operative and surgical treatment.. Depending on the persistence of spinal canal compromise or comminution of the fractured vertebral body, an additional anterior approach is needed.

In the last two decades, attempts have been made to minimize approach-related morbidity . Particularly, the posterior approach to the lumbosacral spine necessitates dissection and retraction of the paraspinal muscles. The use of translaminar screw fixation in conjunction with an ALIF has been suggested to minimize posterior exposure of the lumbar spine .

There is an ongoing debate on the approach to deal with disc herniation related radiculopathy, CSR or CSM, i.e.:. The controversy which of the two approaches is better cannot be generalized but must always be related to the target pathology. In cases with three or more level stenosis, a posterior approach is preferred unless there is no coexisting substantial anterior compression.. Anterior Cervical Discectomy and Fusion.

Posterior Approach to the Cervical Spine. However, usually the anterior approach is preferred because of the minimal collateral soft-tissue damage. The posterior approach to the cervical spine is predominantly indicated in cases with multisegmental degenerative changes or with craniocervical disorders ( Table 2. Indications for the posterior approach to the cranio-cervical-thoracic spine (C0–T.
