Suprascapular Notch
The suprascapular notch (or ''scapular notch'') is a notch in the superior border of the scapula, just medial to the base of the coracoid process. It forms the entrance site into the suprascapular canal. Structure This notch is converted into a foramen by the suprascapular ligament, and serves for the passage of the suprascapular nerve; sometimes the ligament is ossified. The suprascapular vessels varies in number as well as in their course as they run at the suprascapular notch site. The suprascapular artery pass above the suprascapular ligament in most cases. The suprascapular vein been found to pass above the suprascapular ligament as well as passing through the suprascapular notch. Types Two main classification systems exists with others being modified approaches of the same principle. Typing based on subjective observation of the suprascapular notch shape. Introduced by and modified by . There are six basic types of scapular notch: * Type I: Notch is absent. The supe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scapula
The scapula (plural scapulae or scapulas), also known as the shoulder blade, is the bone that connects the humerus (upper arm bone) with the clavicle (collar bone). Like their connected bones, the scapulae are paired, with each scapula on either side of the body being roughly a mirror image of the other. The name derives from the Classical Latin word for trowel or small shovel, which it was thought to resemble. In compound terms, the prefix omo- is used for the shoulder blade in medical terminology. This prefix is derived from ὦμος (ōmos), the Ancient Greek word for shoulder, and is cognate with the Latin , which in Latin signifies either the shoulder or the upper arm bone. The scapula forms the back of the shoulder girdle. In humans, it is a flat bone, roughly triangular in shape, placed on a posterolateral aspect of the thoracic cage. Structure The scapula is a thick, flat bone lying on the thoracic wall that provides an attachment for three groups of muscles: intrin ...

Suprascapular Vein
The suprascapular vein is a vein running above the scapula. It drains into the external jugular vein. It drains the posterior region around the scapula. Structure The suprascapular vein runs above the scapula. It runs above the anterior coracospinal ligament. It lies close to the suprascapular artery. It drains into the external jugular vein. Variation The course of the suprascapular vein is not very variable. In nearly 20% of people, there may be 2 suprascapular veins lying next to each other. In a very small minority, there may be three.

Suprascapular Canal
The suprascapular canal is an anatomical passage between two openings found on the upper dorsal aspect of the shoulder. It is found bilaterally running on superio-lateral aspect of the dorsal surface of the scapula underneath the supraspinatus muscle. Structure The suprascapular canal is an osteofibrous canal situated in the spinoglenoid fossa conveying suprascapular nerve and vessels. Its passage covered by the supraspinatus fascia and connects between its entrance formed by the suprascapular notch (enclosed by the suprascapular ligament) and its exit formed by spinoglenoid notch (enclosed by the spinoglenoid ligament). Clinical significance As the suprascapular nerve travels through the suprascapular canal narrow sites, it can potentially get entrapped leading to suprascapular nerve entrapment syndrome. The causes have different anatomical implications at each site. The mechanisms varies and range from anatomical variations to pathological formations as well as from nerve ...

Great Scapular Notch
The great scapular notch (or ''spinoglenoid notch'') is a notch which serves to connect the supraspinous fossa and infraspinous fossa. It lies immediately medial to the attachment of the acromion to the lateral angle of the scapular spine. The Suprascapular artery and suprascapular nerve pass around the great scapular notch anteroposteriorly. Supraspinatus and infraspinatus are both supplied by the suprascapular nerve, which originates from the superior trunk of the brachial plexus (roots C5-C6).

Nerve Block
Nerve block or regional nerve blockade is any deliberate interruption of signals traveling along a nerve, often for the purpose of pain relief. Local anesthetic nerve block (sometimes referred to as simply "nerve block") is a short-term block, usually lasting hours or days, involving the injection of an anesthetic, a corticosteroid, and other agents onto or near a nerve. Neurolytic block, the deliberate temporary degeneration of nerve fibers through the application of chemicals, heat, or freezing, produces a block that may persist for weeks, months, or indefinitely. Neurectomy, the cutting through or removal of a nerve or a section of a nerve, usually produces a permanent block. Because neurectomy of a sensory nerve is often followed, months later, by the emergence of new, more intense pain, sensory nerve neurectomy is rarely performed. The concept of nerve block sometimes includes ''central nerve block'', which includes epidural and spinal anaesthesia. Local anesthetic nerve bl ...

Osteoplasty
Osteoplasty is the branch of surgery concerned with bone repair or bone grafting. It is the surgical alteration or reshaping of bone. It may be used to relieve pain associated with metastatic bone disease. Percutaneous osteoplasty involves the use of bone cement to reduce pain and improve mobility. Resection osteoplasty is used in joint preserving surgery on the hip and thigh bones.Luca Pierannunzii, MD; Marco d'Imporzano, MTreatment of Femoroacetabular Impingement: A Modified Resection Osteoplasty Technique Through an Anterior Approach ''Healio Orthopedics'' (February 2007, Vol 30, Issue 2).

Stenosis
A stenosis (from Ancient Greek στενός, "narrow") is an abnormal narrowing in a blood vessel or other tubular organ or structure such as foramina and canals. It is also sometimes called a stricture (as in urethral stricture). ''Stricture'' as a term is usually used when narrowing is caused by contraction of smooth muscle (e.g. achalasia, prinzmetal angina); ''stenosis'' is usually used when narrowing is caused by lesion that reduces the space of lumen (e.g. atherosclerosis). The term coarctation is another synonym, but is commonly used only in the context of aortic coarctation. Restenosis is the recurrence of stenosis after a procedure. Types The resulting syndrome depends on the structure affected. Examples of vascular stenotic lesions include: * Intermittent claudication (peripheral artery stenosis) * Angina ( coronary artery stenosis) * Carotid artery stenosis which predispose to (strokes and transient ischaemic episodes) * Renal artery stenosis The types of sten ...

Nerve Compression Syndrome
Nerve compression syndrome, or compression neuropathy, or nerve entrapment syndrome, is a medical condition caused by direct pressure on a nerve. It is known colloquially as a ''trapped nerve'', though this may also refer to nerve root compression (by a herniated disc, for example). Its symptoms include pain, tingling, numbness and muscle weakness. The symptoms affect just one particular part of the body, depending on which nerve is affected. Nerve conduction studies help to confirm the diagnosis. In some cases, surgery may help to relieve the pressure on the nerve but this does not always relieve all the symptoms. Nerve injury by a single episode of physical trauma is in one sense a compression neuropathy but is not usually included under this heading. Syndromes * Upper limb * Lower limb, abdomen and pelvis Signs and symptoms Tingling, numbness, and/or a burning sensation in the area of the body affected by the corresponding nerve. These experiences may occur directly fol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suprascapular Artery
The suprascapular artery is a branch of the thyrocervical trunk on the neck. Structure At first, it passes downward and laterally across the scalenus anterior and phrenic nerve, being covered by the sternocleidomastoid muscle; it then crosses the subclavian artery and the brachial plexus, running behind and parallel with the clavicle and subclavius muscle and beneath the inferior belly of the omohyoid to the superior border of the scapula. It passes over the superior transverse scapular ligament in most of the cases while below it through the suprascapular notch in some cases. The artery then enters the supraspinous fossa of the scapula. It travels close to the bone, running through the suprascapular canal underneath the supraspinatus muscle, to which it supplies branches. It then descends behind the neck of the scapula, through the great scapular notch and under cover of the inferior transverse ligament, to reach the infraspinatous fossa, where it supplies infraspinatus a ...

Ossified
Ossification (also called osteogenesis or bone mineralization) in bone remodeling is the process of laying down new bone material by Cell (biology), cells named osteoblasts. It is synonymous with bone tissue formation. There are two processes resulting in the formation of normal, healthy bone tissue: Intramembranous ossification is the direct laying down of bone into the primitive connective tissue (mesenchyme), while endochondral ossification involves cartilage as a precursor. In fracture healing, endochondral osteogenesis is the most commonly occurring process, for example in fractures of long Bone, bones treated by plaster of Paris, whereas fractures treated by open reduction and internal fixation with metal plates, screws, pins, rods and nails may heal by intramembranous osteogenesis. Heterotopic ossification is a process resulting in the formation of bone tissue that is often atypical, at an extraskeletal location. Calcification is often confused with ossification. Calci ...

Ligament
A ligament is the fibrous connective tissue that connects bones to other bones. It is also known as ''articular ligament'', ''articular larua'', ''fibrous ligament'', or ''true ligament''. Other ligaments in the body include the: * Peritoneal ligament: a fold of peritoneum or other membranes. * Fetal remnant ligament: the remnants of a fetal tubular structure. * Periodontal ligament: a group of fibers that attach the cementum of teeth to the surrounding alveolar bone. Ligaments are similar to tendons and fasciae as they are all made of connective tissue. The differences among them are in the connections that they make: ligaments connect one bone to another bone, tendons connect muscle to bone, and fasciae connect muscles to other muscles. These are all found in the skeletal system of the human body. Ligaments cannot usually be regenerated naturally; however, there are periodontal ligament stem cells located near the periodontal ligament which are involved in the adult regener ...
