It has been known that there is no definitive treatment at reversing stroke in patients with wallenberg syndrome-a lateral medullary stroke affecting the posterior inferior cerebellar artery.
It is, theoretically, contiguous with the lateral pontine and lateral medullary veins, which are often quite small. Together, the lateral mesencephalic, lateral pontine, and lateral medullary veins constitute the lateral longitudinal venous channel of the brainstem. The back surface of the brainstem is a somewhat orphaned property.
Lateral medullary syndrome is a neurological disorder causing a range of symptoms due to ischemia in the lateral part of the medulla oblongata in the brainstem. The ischemia is a result of a blockage most commonly in the vertebral artery or the posterior inferior cerebellar artery.

Most of the complications belong to typical fracture patterns: a3 and so-called “reverse” a2 in ao classification. Cefalo medullary nails (cfn) may not be superior to sliding hip screw plates (shs) in peculiar type of fractures lacking lateral buttresses able to restrain the lateralization of the proximal head-neck fragment.
Optional instruments for the lateral approach: assemble the cutting block and the holder marked “lateral” and slide them onto the medullary reamer. The retrotorsion guide does make retroversion of 0° if aligned with the forearm. Predrill the pinholes through the holes of the resection guide.
Blood pressure regulation with cerebral perfusion maintenance must be established immediately. In the case of ischemic stroke, blood thinners, like heparin or warfarin, reduce the blockage in the arteries supplying the lateral side of the medulla.
Most cases of spontaneous nystagmus in patients with acute lateral medullary infarction (lmi) are similar to unilateral vestibular neuritis (uvn) the nystagmus is mixed horizontaltorsional and usually beats to the intact side (pseudo-vestibular neuritis), with or without gaze-evoked nystagmus (gen). 1, 2, 3 a lesion in the ipsilesional vestibular nuclei and/or vicinity, mainly their cerebellar.

Wallenberg syndrome is also known as lateral medullary syndrome. Common symptoms of wallenberg syndrome include: swallowing difficulties;.
The delta xtend reverse shoulder system prosthesis can be implanted using a superior-lateral deltoid split approach or a delto-pectoral approach. The choice depends on the surgeon’s preference and clinical parameters. The delto-pectoral approach has the advantage of offering an enhanced view of the inferior part of the glenoid.
Calcification correlation the study reconfirmed that dp-ucmgp is also associated with vc, measured by aortic calcification score (ac-24). “our study revealed that dp-ucmgp increases linearly with the increase of the calcification score assessed by a lateral abdominal x-ray (ac-24),” the researchers concluded.

2 medullary canal opening connect the t-handle to the medullary canal opener and use it to open the humeral canal. Start 8mm posterior to the deepest point of the bicipital groove and close to the medial insertion of the supraspinatus. 3 humeral canal preparation use the intramedullary reamers to size the distal medullary.
Screw tap/drill laterally until the threads on the tap portion are completely within the medullary canal of the lateral fragment.
Reverse system may be implanted using either a superior-lateral or delto-pectoral approach. Superior-lateral or delto-pectoral approach depends mainly on surgeon preference and clinical parameters. Revision surgery for instance usually dictates a delto-pectoral approach as it allows a longer humeral incision.
Most of the corticospinal axons cross the midline in the medullary pyramids, thus, the motor cortex in each hemisphere controls the muscles on the contralateral side of the body. After crossing in the medulla, the corticospinal axons descend in the dorsal lateral columns of the spinal cord and terminate in lateral motor pools that control.
Usually, the cerebellum is composed of two lateral halves, or hemispheres, and a this malformation is characterized by downward displacement of the medulla, fourth nerve damage that has already occurred usually cannot be reversed.
They descend as the medial (pontine) and lateral (medullary) reticulospinal tracts through the anterior and lateral funiculi of the spinal cord white matter, respectively. These fibers synapse onto neurons in the anterior grey horns, in the anteromedial portion of laminae vii and viii, where they influence motor neurons supplying paravertebral.

Lateral medullary lesions often also cause impaired smooth pursuit for targets moving contralaterally. This deficit likely reflects damage to the vestibular nucleus. Ocular contrapulsion has been described in association with medial medullary lesions because climbing fibers are disrupted caudally prior to their decussation.
Vertebral artery: distal branches; vertebral artery: superior lateral medullary artery; posterior inferior cerebellar artery: less common than vertebral.
Horner's syndrome, also known as oculosympathetic paresis, is a combination of symptoms that arises when a group of nerves known as the sympathetic trunk is damaged. The signs and symptoms occur on the same side (ipsilateral) as it is a lesion of the sympathetic trunk.
Lateral medullary syndrome, also known as wallenberg syndrome, is a clinical syndrome caused by an acute ischemic infarct of the lateral medulla oblongata.
The reverse shoulder system attaches a component representing the ball of the humerus directly to the scapula and places a socket at the humeral epiphysis to “reverse” the normal shoulder anatomy and restore the normal shoulder center of rotation in patients with large rotator cuff deficiencies, shoulder arthritis and bone loss at the glenoid/humeral joint.
Infarction of the posterior inferior cerebellar artery causes lateral medullary syndrome with hemiataxia, vertigo, dysarthria, ptosis and miosis.

On the lateral view it should be located in the extension of blumensaat’s line. The entry point of the nail is in line with the axis of the medullary canal, just below the crest of the intercondylar notch. The correct position is therefore located anterior and lateral to the proximal attachment of the posterior cruciate ligament.
