Figure 12 Figure 13 Figure 13a. Scapula Plating System Scapula Plating System Acumed is a global leader of innovative orthopaedic and medical solutions.
The burr can be used to create a bicortical defect on the open-door side medial to the junction of the lamina and lateral mass see image below. The drill depth is usually 12 mm in women and centerpiefe men with a smaller bony anatomy; it is usually 14 mm in men. Introduction Arthroscopic studies of.
The superior process of the inferior vertebra lies anterior to the inferior process of the superior vertebra. It is held firmly while the laminar side screws holes are drilled with the 1.
An allograft strut completes the NewBridge system and is also preshaped; struts are available in sizes from mm. Bone grafting options Bone from More information.
The loose laminae should be grasped and stabilized with a suitable clamp eg. At this point it is particularly helpful to correlate the local surface anatomy with the preoperative axial images.

The bone blocks can also be crafted from spinous process autograft medtronkc the surgeon desires. Diagnosis Instability of the thoracic spine. Pullout strength is greater with bicortical purchase and can be considered in patients with poor bone quality or when longer fixation constructs are used; however, there is a risk of endangering nerve roots and the vertebral artery.
The C1 vertebra is termed the atlas, while the C2 vertebra is the axis; these two vertebrae have distinct anatomical features that differentiate them from the rest of the spine.
The subaxial vertebral segments include C3-C7 and are similar to each other in morphology; they include anterior cenferpiece bodies connected to the posterior elements by pedicles bilaterally. Suture anchors Suture anchors have a tapered body that helps reduce insertion torque. The risk of bending, loosening, or breakage of an internal fi xation device during postoperative rehabilitation may be increased if the patient is active, or if the patient is debilitated, demented or otherwise unable to use crutches or other weight supporting devices.
These depths are safe and have been shown to carry a low risk of potential vertebral artery centeripece. At this point, the objective is to ensure that bone separation has been achieved.
The choice of which method a surgeon might use appears centetpiece be primarily a matter of training and familiarity, as are the details of how the laminae are maintained in their open position.
It is important to meticulously control bleeding on posterior cervical approaches, as significant venous bleeding may be encountered. The screwdriver sleeve is optional, and can be used to centeerpiece secure the screw onto the screwdriver while inserting it into the bone. As an alternative centerpiwce bending the laminar shelf of the standard open door plate, one could use the wide mouth plate to allow for easier placement onto the thicker laminae.
However, significant failure rates were noted, particularly in patients with osteoporosis; additionally, removal of the posterior elements and scenarios where flexion forces need to be counteracted showed limited utility for wiring.

Figure 6 Figure 6a Note: Dental Bone Grafting Options. Add new comment Your name. The indications for this technique include congenital stenosis, ossification of the posterior longitudinal ligament, spinal cord tumors, and cervical spondylotic myelopathy CSM involving 3 or more disc levels. The converse would be the case for a left-handed surgeon. The anatomical midline is a relatively avascular intermuscular plane; by remaining within this plane and avoiding dissection into the muscle, bleeding is minimized see image below.
Dissection is continued down onto the spinous processes of the desired levels, taking care to leave intact any soft tissue attachments or posterior ligaments above or below the surgical levels in order to avoid destabilizing adjacent segments. Other preoperative, intraoperative, and postoperative warnings are as follows: Biomechanics is the study of the consequences of application of external force on the spine Motion More information.
January Following your recent MRI scan and consultation with your spinal surgeon, you have been diagnosed with a.
