CLASSIFICATION OF FEMORAL DEFICIENCY Of the numerous available classification systems for femoral deficiency, the two most commonly used are the American Academy of Orthopedic Surgeons (AAOS) classification (Table 1) [30] and the Paprosky classification (Table 2) [31-33]. The AAOS classification is simple and can be used to describe femoral bone deficiencies in both primary and revision settings. The Paprosky classification (Figure 2) correlates well with surgical complexity, can assist in predicting reconstruction options, and is solely utilized in the revision setting. Therefore, we prefer to use this classification when describing femoral bone loss prior to revision surgery. Type I defects (Figure 3) present with essentially normal femoral bone stock. These are often seen in isolated acetabular component revisions and may be managed with …show more content…
Type II (Figure 4) defects are the most commonly encountered. In this scenario, the loss of metaphyseal bone combined with an intact diaphysis precludes the use of standard length implants. While metaphyseal bone loss can be considerable, a type II defect may still contain enough proximal bone to provide metaphyseal support. Common reconstructive options for type II deficiencies include modular metaphyseal engaging stems (with or without sleeves), diaphyseal fit-and-fill stabilizing stems, or long, fully porous coated stems [32]. Type III (Figure 5) defects are further subclassified by the amount of intact diaphyseal bone remaining. Type IIIA defects have ≥4 cm of intact diaphysis, whereas type IIIB defects have <4 cm of intact diaphysis. The reconstruction options are significantly more complex in these scenarios due to the need for adequate distal fixation. When considering using modular cementless stems in type IIIA/B femoral defects, most authors recommend obtaining at least 4 cm of distal fixation. With decreasing distal bone stock, the native femoral bow must be
“The Lovely Bones” is a book written by Alice Sebold. It was published in 2002, and it’s about Susie Salmon, a girl that was murdered and no watches her family and murderer from her own heaven. She tries to balance her feeling and watch out for her family since her murderer is still free and with nobody knowing how dangerous he is. In 2009, a movie adapted from the book came out as well.
Recent research has been focused on distinguishing the most successful augmentation surgery for restoring deficient bone (4, 16-18). Surgical techniques and survival of the bone graft has been vastly highlighted in the literature. ,However, the importance of recipient site on success rate of augmentation procedure has been less issued (16).
As the end of high school draws near for me, I wonder how much have I learned the past few years? How much have I grown and have I evolved into a better person than I was before? Many adolescents and preteens go through a phase where they realize a truth in their life, and that becomes the catalysts of their growth into adulthood. Rule of The Bone by Russell Banks included a main character called Bone, he was a disturbed child named Chappie whose early life consisted with alot of alcoholic and child abuse. While in The Absolutely True Diary of a Part-Time Indian by Sherman Alexie, a boy named Arnold Spirit is grown into a neighborhood of heavy alcoholic abuse and hopelessness. Both were heavily influenced by their childhood, but as each boy
Type IV of OI is much rarer, comprising only 5% of cases. The bones may appear normal at the time of the first...
Bone tissue engineering (BTE) plays an important role in treating bone diseases related to osteoporosis and other orthopedic treatments. Although several methods are used in orthopedic surgery, some bone transport methods such as autografting and allografting have a certain number of disadvantages. Both are expensive methods and they can be exposed to infections and diseases. Therefore, in stead of using these potential risky methods, bone tissue engineering process are used to treat in orthopedic treatments. In general, both tissue engineering and bone tissue engineering have major constituents including stem cells, scaffold, bioreactors and growth factors.
The modern total hip replacement was invented in 1962 by Sir John Charnley. Sir Charnley was an orthopedic surgeon who worked for a small hospital in England. The total hip replacement is considered by many to be the most important operation developed in the 20th century, solely based on the fact that it helps to relieve human suffering. Total hip replacement was first performed in the United States around 1969. Since then there have been more then a hundred of thousands of replacements performed in the United States. One of the first surgeons to perform this surgery was Charles O. Bechtol. In 1969, while he was a professor at UCLA, Bechtol started a total hip replacement program. The artificial hip joint is considered a prosthesis. There are two major types of artificial hip joints, cemented prosthesis and uncemented prosthesis. The type of prosthesis that will be used on the individual patient is decided by the surgeon depending on the patient's age, lifestyle and the experience that the surgeon has with a particular one.
In Bone Gap, by Laura Ruby, perception is everything. The people living in the town love to gossip about everything they see, whether it be accurate or not. For this reason, point of view adds a lot to the novel as the story is told from the views of many different people. The literary device of point of view is very important because the story can greatly change depending on the narrator’s own perception of what is occurring.
Spinal fusion stabilizes the spinal vertebra by fusing the disk spaces between the vertebra. The purpose of Lumbar fusion surgery is designed to help create solid bone between the adjoining vertebra. Classically Autograft bone has been used for fusion. This case study demonstrates the successful use of a synthetic bone graft called Signafuse. Signafuse is a moldable bone graft comprising a proprietary combination of patented bioactive glass particles and biphasic mineral granules suspended in a patented resorbable polymer carrier.
This Preusser (2008) case study involves a 75 year old female, S.P., who fell at home and is admitted to the orthopedic ward for an intracapsular fracture of the hip at the femoral neck (p. 183). Assessment data includes her height is 5’3”, weight is 118 lbs, blood pressure...
The musculoskeletal system is comprised of bones, joints, cartilage, tendons, ligaments, fascia and muscles. Together these body parts work to establish a framework that is the musculoskeletal system. This framework is what gives the body its shape, form, and figure. It stabilizes the body as well as supplies the structural support. The musculoskeletal body features not only provide a framework for your body but allows your ability to create movement. These movements are monitored by the musculoskeletal components which then determine your degree of flexibility. Overall the amount of energy your body uses comes almost entirely from these musculoskeletal functions. Which makes sense because it
The fibula is a leg bone located on the lateral side of the tibia, with which it is connected above and below. It is the smaller of the two bones, and the slenderest of all the long bones, and plays a significant role in stabilizing the ankle and supporting the muscles of the lower leg. The fibula is the smaller, non-weight bearing, of the two bones in the lower leg, while the tibia is the larger, weight bearing bone. The fibula and tibia moves very little relative to each other and the joints that it forms contribute significantly to the function of the lower leg. The joint it forms permit the fibula to adjust its position relative to the tibia, increasing the range of motion of the ankle. Fibular fractures are not often a severe injury, because the bone is supports only about 17% of the body weight.

The skeletal system is composed of two hundred and six bones in the human body. Functions such as the tendons, cartilage, and ligaments connect the bones and tissues together. Bone tissues make up about 18% of the weight of the human body. There are two types of tissue inside the bones. They consist of; compact bone and spongy bone. First, compact bone depicts the main shaft of long bones in the human body such as the arms and legs. Its tissue is dense and hard and it also makes up the outer layer of most bones in our body. Meanwhile, spongy bone tissue is made up of smaller plates occupied with red bone marrow. Mostly, it is found at the ends of long bones such as the head of the femur.
The Skeletal System, also known as the Skeleton make up a framework that support the body and protect the organs. The Skeleton consists of the bones and joints of the body. In the human body there is 300 bones at birth, these then fuse together to make 206 bones in a fully grown adult. The Skeleton is made up of two divisions: The axial and appendicular Skeleton.
