Corner Stitch
The corner stitch is a common suture technique. It used to close wounds that are angled or Y-shaped without appreciably compromising blood supply to the wound tip. The corner stitch is a variation of the horizontal mattress stitch, and is sometimes called the "half-buried horizontal mattress stitch". The needle enters the skin on one side of the obtuse angle of the wound, passes through the deep dermis of the corner flap, and is re-inserted through the dermis of the other side of the obtuse wound angle. It finally re-emerges through the epidermis The epidermis is the outermost of the three layers that comprise the skin, the inner layers being the dermis and hypodermis. The epidermis layer provides a barrier to infection from environmental pathogens and regulates the amount of water rele ... on the side of the obtuse angle, adjacent to the initial entry point.

Surgical Suture
A surgical suture, also known as a stitch or stitches, is a medical device used to hold body tissues together and approximate wound edges after an injury or surgery. Application generally involves using a needle with an attached length of thread. There are numerous types of suture which differ by needle shape and size as well as thread material and characteristics. Selection of surgical suture should be determined by the characteristics and location of the wound or the specific body tissues being approximated. In selecting the needle, thread, and suturing technique to use for a specific patient, a medical care provider must consider the tensile strength of the specific suture thread needed to efficiently hold the tissues together depending on the mechanical and shear forces acting on the wound as well as the thickness of the tissue being approximated. One must also consider the elasticity of the thread and ability to adapt to different tissues, as well as the memory of the threa ...

American Academy Of Family Physicians
The American Academy of Family Physicians (AAFP) was founded in 1947 to promote and maintain high-quality standards for family medicine, an offshoot of the classical general practitioner. It is headquartered in Leawood, Kansas. AAFP is one of the largest medical organizations in the United States, with 136,700 members in 50 U.S. states and territories, in addition to international members. The AAFP was instrumental in establishing family medicine as medicine's 20th primary specialty. The AMA's Council on Medical Education and the independent American Board of Medical Specialties granted approval to a certifying board in family medicine on February 8, 1969. History The AAFP was founded in 1947 as the American Academy of General Practice. The organization's name was changed on October 3, 1971, to "more accurately reflect the changing nature of primary health care". Mission and objectives The mission of the AAFP is to improve the health of patients, families and communities by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wound
A wound is a rapid onset of injury that involves laceration, lacerated or puncture wound, punctured skin (an ''open'' wound), or a bruise, contusion (a ''closed'' wound) from blunt force physical trauma, trauma or compression. In pathology, a ''wound'' is an acute injury that damages the epidermis of the skin. To healing, heal a wound, the body undertakes a series of actions collectively known as the wound healing process. Classification According to level of contamination, a wound can be classified as: * Clean wound – made under sterile conditions where there are no organisms present, and the skin is likely to heal without complications. * Contaminated wound – usually resulting from accidental injury; there are pathogenic organisms and foreign bodies in the wound. * Infected wound – the wound has pathogenic organisms present and multiplying, exhibiting clinical signs of infection (yellow appearance, soreness, redness, oozing pus). * Colonized wound – a chronic situation, ...

Horizontal Mattress Stitch
The horizontal mattress stitch is a suture technique used to close wounds. It everts skin well and spreads tension along the wound edge. This makes it ideal for holding together fragile skin as well as skin under high tension such as the distant edges of a large laceration or as the initial holding suture in complicated repairs. The horizontal mattress is so secure that it can compromise blood supply to the tissue contained within the stitch. This can be helpful to prevent wound bleeding, but it can cause strangulation and skin necrosis if tied too tightly. Sometimes cushioning materials can be placed within the stitch to mitigate this effect. Like other mattress stitches, the horizontal mattress can sometimes leave small skin scars called "railroad marks;" for this reason it is rarely used on the face, and is removed promptly even when placed elsewhere.

Dermis
The dermis or corium is a layer of skin between the epidermis (with which it makes up the cutis) and subcutaneous tissues, that primarily consists of dense irregular connective tissue and cushions the body from stress and strain. It is divided into two layers, the superficial area adjacent to the epidermis called the papillary region and a deep thicker area known as the reticular dermis.James, William; Berger, Timothy; Elston, Dirk (2005). ''Andrews' Diseases of the Skin: Clinical Dermatology'' (10th ed.). Saunders. Pages 1, 11–12. . The dermis is tightly connected to the epidermis through a basement membrane. Structural components of the dermis are collagen, elastic fibers, and extrafibrillar matrix.Marks, James G; Miller, Jeffery (2006). ''Lookingbill and Marks' Principles of Dermatology'' (4th ed.). Elsevier Inc. Page 8–9. . It also contains mechanoreceptors that provide the sense of touch and thermoreceptors that provide the sense of heat. In addition, hair follicles, ...

Epidermis (skin)
The epidermis is the outermost of the three layers that comprise the skin, the inner layers being the dermis and hypodermis. The epidermis layer provides a barrier to infection from environmental pathogens and regulates the amount of water released from the body into the atmosphere through transepidermal water loss. The epidermis is composed of multiple layers of flattened cells that overlie a base layer (stratum basale) composed of columnar cells arranged perpendicularly. The layers of cells develop from stem cells in the basal layer. The human epidermis is a familiar example of epithelium, particularly a stratified squamous epithelium. The word epidermis is derived through Latin , itself and . Something related to or part of the epidermis is termed epidermal. Structure Cellular components The epidermis primarily consists of keratinocytes ( proliferating basal and differentiated suprabasal), which comprise 90% of its cells, but also contains melanocytes, Langerhans c ...
