Posterior Commissure Image

Anatomical terms of neuroanatomy. [edit on Wikidata] The posterior commissure (also known as the epithalamic commissure) is a rounded band of white fibers crossing the middle line on the dorsal aspect of the rostral end of the cerebral aqueduct. It is important in the bilateral pupillary light reflex.

Posteriorly the labia are not really joined, but appear to become lost in the neighboring integument, ending close to, and nearly parallel with, each other. Together with the connecting skin between them, they form the posterior labial commissure or posterior boundary of the pudendum. There is no image containing this anatomical part yet.

On the basis of clinical observations, the nucleus of the posterior commissure (PCom) has long been suspected as being involved in the generation of upward eye movements, since lesions in patients resulted in upward gaze paralysis ( Christoff, 1974 ). To date the role of the PCom in vertical gaze has not been fully explained.

Anatomy Of The Posterior Upper Leg Hamstrings Image

The hamstring muscles, or simply the hamstrings, are a group of three long muscles located in the posterior compartment of the thigh, shaping up the surface anatomy of this region. These muscles are the biceps femoris, semimembranosus and semitendinosus muscles.

Posterior Shoulder Dislocation1 Image

A posterior dislocation should be considered as a differential in any episode of shoulder pain and immobility after a seizure. Incidence. The shoulder joint is the most commonly dislocated joint presenting to hospital. Posterior dislocations account for 2-4% of all shoulder dislocations.

The ideal image for identifying a posterior dislocation is a axillary film, with the patients arm abducted at 70-90 degrees and the image taken from an angle of 45 degrees through the axilla. This should be done as part of a standard set of imaging after shoulder injury, along with an AP and lateral view of the shoulder.

Posterior shoulder dislocation. Posterior shoulder dislocations are far less common than anterior shoulder dislocations and can be difficult to identify if only AP projections are obtained. A high index of suspicion is helpful.

The ideal image for identifying a posterior dislocation is a axillary film, with the patients arm abducted at 70-90 degrees and the image taken from an angle of 45 degrees through the axilla. This should be done as part of a standard set of imaging after shoulder injury, along with an AP and lateral view of the shoulder.

Because posterior shoulder dislocations are uncommon (< 4% of shoulder dislocations), and often diagnosed late, obtain orthopedic consultation prior to reduction. Findings on anteroposterior x-rays may be subtle. A scapular Y view or an axillary view x-ray should be done. A CT scan should be done if the dislocation is unclear on x-ray.

Typically the humeral head is forced posteriorly in an internal rotation while the arm is abducted 1,3. In adults, convulsive disorders are the most common cause. Electrocution is a classic but uncommon cause of posterior shoulder dislocation.

Other findings in posterior dislocation may include: Anterior contour of the shoulder absent (flattened anterior shoulder), Prominent coracoid and acromion, Rounded posterior shoulder, Palpable posterior humeral head.
