Coccygectomy
Coccygectomy is a surgical procedure in which the coccyx or tailbone is removed. It is considered a required treatment for sacrococcygeal teratoma and other germ cell tumors arising from the coccyx. Coccygectomy is the treatment of last resort for coccydynia (coccyx pain) which has failed to respond to nonsurgical treatment. Non surgical treatments include use of seat cushions, external or internal manipulation and massage of the coccyx and the attached muscles, medications given by local injections under fluoroscopic guidance, and medications by mouth. To remove the coccyx, an incision is made from the tip of the coccyx to its joint with the sacrum. The coccyx is cut away from the surrounding tissues, cut off at the joint with the sacrum, and removed. If the tip of the sacrum is rough, it is filed down. The wound is closed in layers.An improved technic of coccygectomy. Clinical Orthopedics, 85: 143-145, 1972. Richard C Gardner. http://www.coccyx.org/medabs/gardner.htmPrevention o ...

Coccyx
The coccyx ( : coccyges or coccyxes), commonly referred to as the tailbone, is the final segment of the vertebral column in all apes, and analogous structures in certain other mammals such as horses. In tailless primates (e.g. humans and other great apes) since ''Nacholapithecus'' (a Miocene hominoid),Nakatsukasa 2004, ''Acquisition of bipedalism'' (SeFig. 5entitled ''First coccygeal/caudal vertebra in short-tailed or tailless primates.''.) the coccyx is the remnant of a vestigial tail. In animals with bony tails, it is known as ''tailhead'' or ''dock'', in bird anatomy as ''tailfan''. It comprises three to five separate or fused coccygeal vertebrae below the sacrum, attached to the sacrum by a fibrocartilaginous joint, the sacrococcygeal symphysis, which permits limited movement between the sacrum and the coccyx. Structure The coccyx is formed of three, four or five rudimentary vertebrae. It articulates superiorly with the sacrum. In each of the first three segments may ...

List Of Surgeries By Type
Many surgical procedure names can be broken into parts to indicate the meaning. For example, in gastrectomy, "ectomy" is a suffix meaning the removal of a part of the body. "Gastro-" means stomach. Thus, ''gastrectomy'' refers to the surgical removal of the stomach (or sections thereof). "Otomy" means cutting into a part of the body; a ''gastrotomy'' would be cutting into, but not necessarily removing, the stomach. And also "pharyngo" means pharynx, "laryngo" means larynx, "esophag" means esophagus. Thus, "pharyngolaryngoesophagectomy" refers to the surgical removal of the three. The field of minimally invasive surgery has spawned another set of words, such as ''arthroscopic'' or ''laparoscopic'' surgery. These take the same form as above; an arthroscope is a device which allows the inside of the joint to be seen. List of common surgery terms Prefixes * ''mono-'' : one, from the Greek μόνος, ''monos'', "only, single" * ''angio-'' : related to a blood vessel, from the Gre ...

Sacrococcygeal Teratoma
Sacrococcygeal teratoma (SCT) is a type of tumor known as a teratoma that develops at the base of the coccyx (tailbone) and is thought to be primarily derived from remnants of the primitive streak. Sacrococcygeal teratomas are benign 75% of the time, malignant 12% of the time, and the remainder are considered "immature teratomas" that share benign and malignant features. Benign sacrococcygeal teratomas are more likely to develop in younger children who are less than 5 months old, and older children are more likely to develop malignant sacrococcygeal teratomas. The Currarino syndrome, due to an autosomal dominant mutation in the MNX1 gene, consists of a presacral mass (usually a mature teratoma or anterior meningocele), anorectal malformation and sacral dysgenesis. Presentation Complications Maternal complications of pregnancy may include mirror syndrome. Maternal complications of delivery may include a Cesarean section or, alternatively, a vaginal delivery with mechanical dyst ...

Germ Cell Tumor
Germ cell tumor (GCT) is a neoplasm derived from germ cells. Germ-cell tumors can be cancerous or benign. Germ cells normally occur inside the gonads (ovary and testis). GCTs that originate outside the gonads may be birth defects resulting from errors during development of the embryo. Classification GCTs are classified by their histology, regardless of location in the body. However, as more information about the genetics of these tumors become available, they may be classified based on specific gene mutations that characterize specific tumors. They are broadly divided in two classes: * The germinomatous or seminomatous germ-cell tumors (GGCT, SGCT) include only germinoma and its synonyms dysgerminoma and seminoma. * The nongerminomatous or nonseminomatous germ-cell tumors (NGGCT, NSGCT) include all other germ-cell tumors, pure and mixed. The two classes reflect an important clinical difference. Compared with germinomatous tumors, nongerminomatous tumors tend to grow faster, have ...

Coccydynia
Coccydynia is a medical term meaning pain in the coccyx or tailbone area, often brought on by a fall onto the coccyx or by persistent irritation usually from sitting. Synonyms Coccydynia is also known as coccygodynia, coccygeal pain, coccyx pain, or coccalgia. Anatomy Structure Coccydynia occurs in the lowest part of the spine, the coccyx, which is believed to be a vestigial tail, or in other words the “tail bone”. The name coccyx is derived from the Greek word for cuckoo due to its beak like appearance. The coccyx itself is made up of 3 to 5 vertebrae, some of which may be fused together. The ventral side of the coccyx is slightly concave whereas the dorsal aspect is slightly convex. Both of these sides have transverse grooves that show where the vestigial coccygeal units had previously fused. The coccyx attaches to the sacrum from the dorsal grooves, with the attachment being either a symphysis or as a true synovial joint, and also to the gluteus maximus muscle, the coccyge ...

General Anaesthesia
General anaesthesia (UK) or general anesthesia (US) is a medically induced loss of consciousness that renders the patient unarousable even with painful stimuli. This effect is achieved by administering either intravenous or inhalational general anaesthetic medications, which often act in combination with an analgesic and neuromuscular blocking agent. Spontaneous ventilation is often inadequate during the procedure and intervention is often necessary to protect the airway. General anaesthesia is generally performed in an operating theater to allow surgical procedures that would otherwise be intolerably painful for a patient, or in an intensive care unit or emergency department to facilitate endotracheal intubation and mechanical ventilation in critically ill patients. A variety of General anesthetic, drugs may be administered, with the overall goal of achieving unconsciousness, amnesia, analgesia, loss of reflexes of the autonomic nervous system, and in some cases paralysis of ske ...

Perineal Hernia
Perineal hernia is a hernia involving the perineum (pelvic floor). The hernia may contain fluid, fat, any part of the intestine, the rectum, or the bladder. It is known to occur in humans, dogs, and other mammals, and often appears as a sudden swelling to one side (sometimes both sides) of the anus. A common cause of perineal hernia is surgery involving the perineum. Perineal hernia can be caused also by excessive straining to defecate. Other causes include prostate or urinary disease, constipation, anal sac disease (in dogs), and diarrhea. Atrophy of the levator ani muscle and disease of the pudendal nerve may also contribute to a perineal hernia. In humans In humans, a major cause of perineal hernia is perineal surgery without adequate reconstruction. In some cases, particularly surgeries to remove the coccyx and distal sacrum, adequate reconstruction is very difficult to achieve. The posterior perineum is a preferred point of access for surgery in the pelvic cavity, parti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rump (croup)
The rump or croup, in the external morphology of an animal, is the portion of the posterior dorsum – that is, posterior to the loins and anterior to the tail. Anatomically, the rump corresponds to the sacrum. The tailhead or dock is the beginning of the tail, where the tail joins the rump. It is known also as the base or root of the tail, and corresponds to the human sacrococcygeal symphysis. In some mammals the tail may be said to consist of the tailbone (meaning the bony column, muscles, and skin) and the skirt (meaning the long hairs growing from the tailbone). In birds, similarly, the tail consists of tailbone and tailfan (tail fan). Some animals are subjected to docking, the amputation of the tailbone at or near the dock. These include dogs, cats, sheep, pigs, and horses. Humans have a remnant tail, the coccyx, and the human equivalent of docking is coccygectomy. Usage Usage varies from animal to animal. Birds and cattle are said to have a rump and tailhead ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Docking (animal)
Docking is the intentional removal of part of an animal's tail or, sometimes, ears. The term cropping is more commonly used in reference to the cropping of ears, while ''docking'' more commonly—but not exclusively—refers to the tail. The term tailing is also commonly used. The term arises because the living flesh of the tail, from which the animal's tail hairs grow, commonly is known as the dock. Pigs Tail-docking in pigs is typically carried out without anaesthetic when the piglet is three to four days old and causes acute trauma and pain. Commercially raised domestic pigs kept in close quarters have their tails docked to prevent chewing or biting each other's tails. Pig producers in Brazil and Thailand have stopped tail docking for animal welfare reasons. Routine tail-docking without anesthesia is illegal in the EU. The practice continues among large US pig producers. Sheep Many breeds of sheep have their tails docked to reduce the buildup of faeces which can enco ...

Docking (dog)
Docking is the removal of portions of an animal's tail. While docking and bobbing are more commonly used to refer to removal of the tail, the term cropping is used in reference to the ears. Tail docking occurs in one of two ways. The first involves constricting the blood supply to the tail with a rubber ligature for a few days until the tail falls off. The second involves the severance of the tail with surgical scissors or a scalpel. The length to which tails are docked varies by breed, and is often specified in the breed standard. Docking is illegal, or restricted, in many countries. Some dog breeds have naturally occurring bobtail lines. These appear similar to docked dogs but are a distinct naturally occurring phenotype. History Purpose Historically, tail docking was thought to prevent rabies, strengthen the back, increase the animal's speed, and prevent injuries when ratting, fighting, and baiting. Tail docking is done in modern times either for prophylactic, therapeu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surgical Oncology
Surgical oncology is the branch of surgery applied to oncology; it focuses on the surgical management of tumors, especially cancerous tumors. As one of several modalities in the management of cancer, the specialty of surgical oncology has evolved in steps similar to medical oncology (pharmacotherapy for cancer), which grew out of hematology, and radiation oncology, which grew out of radiology. The Ewing Society known today as the Society of Surgical Oncology was started by surgeons interested in promoting the field of oncology. Complex General Surgical Oncology was ratified by a specialty Board certification in 2011 from the American Board of Surgery. The proliferation of cancer centers will continue to popularize the field, as will developments in minimally invasive techniques, palliative surgery, and neo-adjuvant treatments. Debate Whether surgical oncology constitutes a medical specialty ''per se'' is the topic of a heated debate. Today, some would agree that it is simply impos ...
