Hip Anatomy
The hip joint is a large ball and socket joint designed to withstand significant stresses such as supporting our body weight when running and jumping, in addition to the normal wear and tear of daily activities such as walking and stair climbing. The hip joint is comprised of the head (“ball”) of the femur (“thigh bone”) and the acetabulum (“socket”) of the pelvis. Surrounding the hip joint are many tough ligaments that provide support and protection to prevent the dislocation of the joint but allow a wide range of movements. The strong muscles of the hip region also help to hold the hip joint together, to move the bones and prevent dislocation. Cartilage lines both the acetabulum and the head of the femur, providing a smooth surface and preventing friction between the moving bones and allowing them to glide smoothly past each other. Between the layers of the hyaline cartilage, there are synovial membranes that secrete watery synovial fluid to lubricate the joint. It is this cartilage that is the primary source of pain in a hip joint with osteoarthritis (OA).
Common Causes of Hip Pain
There are many causes of hip pain including injury, trauma, rheumatoid and OA, labrum tears and impingement, osteoporosis, pinched nerves, tendinitis, bursitis

Avoid lying on the affected side, bending, twisting and walking around until you feel more comfortable. Avoid any motions that cause an increase in your pain. Begin gentle movements, like lifting your leg, when your pain subsides; begin weight bearing by putting your foot on the floor while sitting and assessing for any pain before standing. If your symptoms or pain does not subside in a few days call your physician. Conservative medical treatment may consist of an X-ray or MRI to confirm the
So far, various techniques have been used for reconstruction and regeneration of maxillary and mandibular bone defects. Autogenous bone grafting, guided bone regeneration (GBR), distraction osteogenesis and nerve transpositioning are among these regenerative techniques (1-8). Decision making for the treatment could be influenced by the type, size and location of the bone defects (2, 3, 9, 10). GBR had high success rate in treating small alveolar defects such as dehiscence or fenestration. Regenerative bony walls around the defect with ingrowing blood vessels can begin osteogenesis (11) larger bone defects with insufficient regenerative walls and an low quality avascular bed need varied amount of autogeneous bone graft from extra oral or intra oral donor sites, however, the patient may suffer from complications in donor site as well as bone graft resorption.(10, 12-15)
Symptoms of osteoarthritis often develop slowly and worsen over the years. Signs and symptoms include: pain in joints, tenderness, stiffness, loss of flexibility, grating sensation joints (from bone on bone), and bone spurs.
Osteoarthritis is a degenerative joint condition that primarily affects the hands, spine and the ankles and hips. It is known to be associated with aging, and is concerned with the cartilage that protects the joints (the meeting place of two bones). Normal cartilage allows for bones to slide over each other uniformly, acting as a shock absorber to any damage. However cartilage in osteoarthritis, located at the ends of the bones erodes and deteriorates, causing friction and hence pain, swelling and restricted movement. Therefore in osteoarthritic both the composition and appearance of the cartilage alters, while the body attempts to repair this damaged cartilage is broken down faster than it can be built up. A defective repair process can cause bone overgrowth, bone spur/osteocytes to form which can be seen at the ends of the joints. In osteoarthritis the bones come in close contact with each other, and wear away leaving the bone exposed and unprotected.
Osteoarthritis (OA) is the most common form of arthritis, affecting more than 27 million Americans (LeMone, Burke, Bauldoff, 2011). It is caused when the cartilage in the joints breaks down, causing the bones of the joint to rub against one another. This causes pain, stiffness, and loss of motion in the joint. Osteoarthritis is most prevalent in those 65 and older, but can affect those of any age. In addition, African Americans and Hispanics report a higher incidence of arthritis than Caucasians (LeMone, Burke, Bauldoff, 2011). Although the cause is unknown, it is believed that the increasing age of the population, prevalence of obesity and injuries add to the progression of the condition. Osteoarthritis can affect any joint in the body; however, those of the hand, hip, and knee are often the most common. This condition may be asymptomatic, or may present symptoms including soreness, stiffness and pain. The symptoms are more common in the older population, those with limited activity levels, and those who are obese. Joint cartilage thins over time, causing an increased risk for symptoms in the elderly, and obesity puts extra pressure on the joints during activity. Osteoarthritis is commonly diagnosed with the use of a physical assessment along with results of radiology testing such as X-Ray and MRI.
The skeletal system is made of all the bones, connective tissues and joints in the body. Bones, cartilage are some of the bones that make up the Skeletal system. The Skeletal system helps perform important everyday functions, for example; support, movement and protection, etc. The skeletal system helps form blood cells. The skeletal system helps store calcium and phosphorus, which is important and beneficial to the other functions in the body.

Total Hip Replacement (THR) is a surgical procedure that relieves pain from most kinds of hip arthritis, thus helping to improve the quality of life for the majority of the patients that undergo the operation. Arthritis simply means "inflammation of a joint." Arthritis can occur in any joint in the body. The main symptom of arthritis is pain which usually worsens with activity and weight bearing. This pain may be relieved most of the time through rest. There are over 100 types of arthritis but less than a handful account for over than 95 percent of the hip replacements that are performed. Some of these include Osteoarthritis (causes deterioration of the cartilage and the growth of bone spurs), Rheumatoid arthritis and Osteonecrosis of the femoral head. Doctors suggest that before considering hip replacement surgery for arthritis that the patient tries a number of non-operative interventions. Your doctor may have you consider little things such as weight loss (most arthritis is caused due to the weight bearing on a joint), activity modification or even the use of a cane. Patients should consider THR when daily living activities become harder to accomplish due to the pain. These activities would include walking, climbing stairs or other moderate pastimes. Anti-inflammatory medications which will help reduce the inflammation from the arthritis and reduce your pain may also be prescribed by the patient's doctor.
Often, the pain extends from the lower back all the way to the back of the thigh and down through the leg. Depending on where the sciatic nerve is affected, the pain may also extend to the foot or toes.
Arthrogryposis is a disorder in which a child is born with joint contractures; this means some of their joints may be stuck in one position (curved or crooked). Children born with this disorder may have thin, weak, stiff, or missing muscles around these joints. The most common cause of arthrogryposis is fetal akinesia which is where the baby doesn’t move around a lot in the womb during development. Extra tissue can form in the joints making movement more difficult for the child to move. The reasons that fetal akinesia can take place may be because the womb was abnormally shaped so there wasn’t enough room for the baby to move around, amniotic fluid may have leaked out of the womb, or the baby’s parts did not form normally such as joints, bones, and muscles. They have also found that in approximately one third of the children who have this disorder have been determined to be a genetic cause.
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.
• When sitting or lying down, raise (elevate) your feet. Try putting some pillows underneath your lower legs.
The history of anatomy and physiology dates back to ancient Egyptian times when humans were mummified after death and bodies would be stripped of their internal organs during the embalming process. It was not until much later when Hippocrates II, known as the father of medicine, was the first to write about human anatomy. Shortly after that, the Alexandrian Medical School was established, where human dissection was allowed for the first time, which promoted research and new discoveries in the field. From there, many other influential researchers came up with theories regarding the cardiovascular and nervous systems, etc; however, the missing links in some of the earlier theories was found with the discovery of the microscope, which changed the focus of research and led to many advancements in the field.
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.
