	Knee Osteotomy - Definition, Purpose, Demographics, Description, Diagnosis/preparation, Aftercare, Risks, Normal ...
		Knee osteotomy is surgery that removes a part of the bone of the joint of either the bottom of the femur (upper leg bone) or the top of the tibia (lower leg bone) to increase the stability of the knee.
		Osteotomy is performed to cut cartilage and increase the fit and alignment of the ends of the femur and tibia for smooth articulation.
		Since the goal of osteotomy is to shift weight from a symptomatic cartilage to an unsymptomatic area to relieve both an instability and pain due to excessive contact, alignment of the knee is assessed for pressure distribution along the mechanical axis and the loading axis.

	Hip Osteotomy - Definition, Purpose, Demographics, Description, Diagnosis/preparation, Aftercare, Risks, Normal ...
		A hip osteotomy is a surgical procedure in which the bones of the hip joint are cut, reoriented, and fixed in a new position.
		Osteotomies are performed in these patients, using the patient's own tissue in order to restore joint function in the hip and eliminate pain.
		Monique Laberge, Ph.D. A hip osteotomy is performed in a hospital by surgeons who specialize in the treatment of hip disorders, such as reconstructive orthopedic surgeons, pediatric orthopedic surgeons, and physiatrists.

	Osteotomy for osteoarthritis
		Osteotomy ("bone cutting") is a procedure in which a wedge of bone is removed from a damaged joint.
		Osteotomy may allow an active person to postpone a total joint replacement for a few years and is usually reserved for younger people.
		Osteotomy is used if destruction of the knee cartilage mainly affects a single disc of cartilage: the disc (meniscus) either on the inner part or on the outer part of the knee joint.

	Osteotomy for osteoarthritis
		Osteotomy ("bone cutting") is a procedure in which a surgeon removes a wedge of bone near a damaged joint.
		In knee osteotomy for osteoarthritis of the inner knee, your surgeon removes bone from the outer side of the lower leg bone near the knee.
		Doctors use osteotomy if destruction of the knee cartilage mainly affects a single disc of cartilage: the disc (meniscus) either on the inner part or on the outer part of the knee joint.

	Osteotomy as a method of the treatment of lower limb deformities
		Osteotomy is an operation in which a bone is cut, enabling a surgeon to reposition it.
		An osteotomy may be performed to lengthen or shorten a leg, to correct bowed or bent legs, or to reset a fracture.
		Osteotomy as a treatment method is in progress from the middle of the XIX century until the present days.

	The Hip Clinic - Femoral Osteotomy - Consultant Orthopaedic Surgeon J.N. O'Hara FRCS FRCSI MCh
		Osteotomy of the femur is usually a reasonably stable operation and partial weightbearing is usually possible, and to be encouraged, in the immediate aftermath of the operation.
		The osteotomy may take three or four months to heal and post-operative weightbearing is likely to be significantly restricted for a large proportion of that time.
		An Osteotomy, of any kind, is an operation where a bone is cut, usually realigned in some way, and then re-fixed to heal in its new configuration.

	Modified Salter's innominate osteotomy
		In Salter’s osteotomy the entire acetabulum, together with the pubis and ischium, is rotated anteriorly and laterally as a unit, with the symphysis pubis acting as a hinge.
		Salter’s osteotomy is an operation devised primarily for the treatment of acetabular displasia, a secondary stabilizing treatment of open reduction of congenital displacement of the hip, paralytic dislocation or subluxation in children, and a secondary treatment for residual or recurrent subluxation or dislocation following other methods.
		In Salter’s osteotomy, the bone graft used for the stabilization of the osteotomy is the cancellous bone taken from the iliac crest.

	Periacetabular Osteotomy \| Spine Chirurgy
		The third osteotomy trait departs from the iliac antero inferior spina and heads towards the upper strait.
		The osteotomy is completed by connecting the first two traits by a third that passes a centimetre before the large sciatica notch.
		The osteotomy is finished by using a Ganz scissor to completely detach and free the acetabulum.

	What is Osteotomy?
		An osteotomy is an elective surgical procedure, performed under general anesthesia, in which a bone is cut or a portion is taken out in order to fix a bad bone alignment, to shorten or lengthen the bone, or to correct damage due to osteoarthritis.
		An osteotomy is needed when a bone has healed badly or crooked, or when a deformity is caused by disease or disorder.
		Osteotomies are commonly performed on patients who have experienced a break that has healed crookedly, or has grown slower than the bones around it.

	Knee Society
		Osteotomy is also used as an alternative treatment to total knee replacement in younger and active patients.
		The most common type of osteotomy performed on arthritic knees is a high tibial osteotomy, which addresses cartilage damage on the inside (medial) portion of your knee.
		During a high tibial osteotomy, surgeons remove a wedge of bone from the outside of your knee, which causes your leg to bend slightly inward.

	The Ludloff Osteotomy (Site not responding. Last check: 2007-10-19)
		The opening abductory base wedge osteotomy, the crescentic osteotomy of the base of the first metatarsal the transpositional/rotational base osteotomy, the wedge shelf osteotomy, as well as the first metatarsal-cuneiform arthrodesis procedures are also viable options to reduce this deformity (4,5).
		The Ludloff osteotomy was first described in 1918 and is a through-and-through osteotomy in the transverse plane extending dorsal-proximal to plantar-distal when viewed in the sagittal plane.
		The osteotomy should be "biased" dorsal- medial to plantar-lateral in the frontal plane such that when the capital fragment is transposed laterally to reduce the intermetatarsal angle, the metatarsal head will translocate plantarly.

	South Australian Orthopaedic Registrars' Notebook
		Beneficial effects of osteotomy in treatment of OA are produced by decreasing unit load by restoring congruency, decreasing muscle forces and restoring a functional arch of motion.
		Pelvic osteotomies are indicated for primary hip pathology eg hip dysplasia +/- femoral osteotomy.
		Varus or Valgus osteotomies require either medial or lateral displacement of the shaft of the femur to maintain the mechanical axis of the leg through the centre of the knee.

	Technologies - Reconstructive Osteotomy
		Osteotomy of the thigh bone for arthritis of the hip joint
		Cutting and resetting of the thigh bone for arthritis of the hip was in the past the most important surgical treatment for this disease.
		With the advent of successful implant surgery the use of osteotomy has become much reduced: osteotomy usually gives improved function and lack of pain for only a limited period – up to 15 years – whereas arthroplasty promises a much longer good result.

	Ankylosing Spondylitis Treated with Pedicle Subtraction Osteotomy
		After the osteotomy is done, it is usually necessary to perform anterior structural grafting at the levels of osteotomy to prevent anterior collapse and settling.
		In a pedicle subtraction osteotomy, the posterior elements are carefully resected along with a decancellation of the body via a transpedicular route.
		A pedicle subtraction osteotomy can be expected to achieve 35-40° of correction and potentially avoid the need for an anterior procedure, because the anterior and middle columns are closed with closure of the posterior column osteotomy.

	Tibial Osteotomy
		During a tibial osteotomy, the surgeon removes a wedge shaped portion of the shin bone (tibia) to help compensate for a deformity in the knee joint.
		A tibial osteotomy usually involves cutting a wedge-shaped portion of bone from the tibia to correct the alignment of the knee.
		Because the tibial osteotomy involves cutting the bone and having it mend back together, a significant postoperative course of therapy needs to be followed.

		The osteotomy improved their functional scores, reduced pain, and decreased the frequency of bleeding at a mean 9-year follow-up.
		To date, there is only one report on the use of supramalleolar osteotomy for the treatment of posttraumatic ankle arthritis.26 In this study Takakura et al., reported the outcome of nine patients who underwent a supramalleolar osteotomy for the treatment of a posttraumatic varus deformity of the ankle.
		We have noted the indications for distal tibia osteotomy in cases of primary or secondary osteoarthritis of the ankle by shifting the loads and redistributing stresses to a part of the ankle joint not involved in the degenerative process (Fig.

	Femoral Osteotomy
		History of the Procedure: Proximal femoral osteotomy was a technique used in adults in the early part of the 20th century for the treatment of hip dysplasia and osteoarthritis.
		Varus and valgus- producing osteotomies were aimed at maximizing joint congruity and redistributing the weightbearing load across the femoral head to a less affected area.
		For varus-producing osteotomies, the bone is cut before the blade plate is inserted (due to impingement of the plate on the femoral shaft), and the seating chisel is used to help reduce the proximal fragment.

	Southern California Veterinary Surgical Group - Triple Pelvic Osteotomy
		The Triple Pelvic Osteotomy (TPO) is a surgery that preserves the natural hip joint, eliminates the subluxation (laxity) and prevents the progression of arthritis.
		The Triple pelvic Osteotomy is a surgical procedure which rotates the shallow acetabulum to provide improved coverage of the femoral head.
		It is important to note that while age is important, it is not as critical for success as the condition of joint surfaces.

	High Tibial Osteotomy - Medical Computing Lab at Queen's University
		An osteotomy is a surgical procedure to realign a bone in order to change the biomechanics of a joint, especially to change the force transmission through a joint.
		In particular, the high tibial osteotomy (HTO) is a corrective surgical procedure in which the upper part of the tibia is resected so that the lower limb can be realigned.
		The most common form of HTO is the closing wedge osteotomy, in which the realignment is achieved by removing a lateral wedge of bone from the proximal tibia.

	RedOrbit - Health - Periacetabular Osteotomy in Patients With Down's Syndrome (Site not responding. Last check: 2007-10-19)
		The modified Bernese periacetabular osteotomies were performed by the senior author (MBM) as described by Murphy and Millis.10 One hip (1R) had an intertrochanteric varus femoral osteotomy at the same time as the periacetabular osteotomy.
		Various osteotomies have been used in the treatment of acetabular dysplasia in patients with Down's syndrome, with variable results.4"6 Aprin et al6 described the management of six children with Down's syndrome and dislocation of the hip.
		As a result we believe that the modified Bernese periacetabular osteotomy was preferable to alternative procedures such as Chiari osteotomy, hip arthrodesis and total hip arthroplasty although the radiographie criteria were not ideal.

	TIBIAL PLATEAU LEVELING OSTEOTOMY - TPLO (Site not responding. Last check: 2007-10-19)
		The Tibial Plateau Leveling Osteotomy is used to neutralize the effect of cranial Tibial thrust (Fig.5).
		In the traditional model of stifle joint stability, the cranial and caudal cruciate ligaments are considered the sole resistance to cranial and caudal sliding movements of the Tibial plateau in relation to the femoral condyles (cranial and caudal "drawer" motions).
		Tibial Plateau Leveling Osteotomy is used to negate the effects of cranial Tibial thrust by leveling the Tibial plateau.
