  • Compression Garments for Leg Lymphoedema
    Compression garments for leg lymphoedema You have been fitted with a compression garment to help reduce the lymphoedema in your leg. Compression stockings work by limiting the amount of fluid building up in your leg. They provide firm support, enabling the muscles to pump fluid away more effectively. They provide most pressure at the foot and less at the top of the leg so fluid is pushed out of the limb where it will drain away more easily. How do I wear it? • Wear your garment every day to control the swelling in your leg. • Put your garment on as soon as possible after getting up in the morning. This is because as soon as you stand up and start to move around extra fluid goes into your leg and it begins to swell. • Take the garment off before bedtime unless otherwise instructed by your therapist. We appreciate that in hot weather garments can be uncomfortable, but unfortunately this is when it is important to wear it as the heat can increase the swelling. If you would like to leave off your garment for a special occasion please ask the clinic for advice. What should I look out for? Your garment should feel firm but not uncomfortable: • If you notice the garment is rubbing or cutting in, adjust the garment or remove it and reapply it. • If your garment feels tight during the day, try and think about what may have caused this. If you have been busy, sit down and elevate your leg and rest for at least 30 minutes.

Discussion Assessment of an ankle injury begins with a detailed history to determine the severity, mechanism and velocity of the injury, what happened immediately after and whether there is a past history of inadequately rehabilitated ankle injury. Examination involves assessment of weight bearing, inspection, palpation, movement, and application of special examination tests. Plain X-rays may be helpful to exclude a fracture. If the diagnosis is uncertain, consider second The majority of ankle injuries are inversion and plantar line investigations including bone scan, computerised flexion injuries that result in damage to the lateral tomography or magnetic resonance imaging, and referral to a ligament complex (Figure 1).

  • Intramedullary Nailing for Femur Fracture Management a Guide for Parents
    514-412-4400, ext. 23310 thechildren.com/trauma Intramedullary Nailing for Femur Fracture Management A Guide for Parents The femur is the longest bone in the body. It begins at the hip joint and ends at the knee. A femur fracture is typically sustained from high-energy impact such as motor vehicle collisions, falls from playground equipment, falls from furniture or resulting from a twisting mechanism. Children who have sustained a femur fracture are hospitalized on the Surgical/Trauma Unit in order to receive appropriate medical, nursing and rehabilitation care. FEMUR (thigh bone) Head Greater Neck trochanter Lesser trochanter Shaft Medial Lateral epicondyle epicondyle Illustration Copyright © 2016 Nucleus Medical Media, All rights reserved. © 2016 MCH Trauma. All rights reserved. FEMUR FRACTURE MANAGEMENT The pediatric Orthopedic Surgeon will assess your child in order to determine the optimal treatment method. Treatment goals include: achieving proper bone realignment, rapid healing, and the return to normal daily activities. The treatment method chosen is primarily based on the child’s age but also taken into consideration are: fracture type, location and other injuries sustained if applicable. Prior to the surgery, your child may be placed in skin traction. This will ensure the bone is in an optimal healing position until it is surgically repaired. Occasionally, traction may be used for a longer period of time. The surgeon will determine if this management is needed based on the specific fracture type and/or location. ELASTIC/FLEXIBLE INTRAMEDULLARY NAILING This surgery is performed by the Orthopedic Surgeon in the Operating Room under general anesthesia. The surgeon will usually make two small incisions near the knee joint in order to insert two flexible titanium rods (intramedullary nails) Flexible through the femur.

  • ANTERIOR KNEE PAIN Home Exercises
    ANTERIOR KNEE PAIN Home Exercises Anterior knee pain is pain that occurs at the front and center of the knee. It can be caused by many different problems, including: • Weak or overused muscles • Chondromalacia of the patella (softening and breakdown of the cartilage on the underside of the kneecap) • Inflammations and tendon injury (bursitis, tendonitis) • Loose ligaments with instability of the kneecap • Articular cartilage damage (chondromalacia patella) • Swelling due to fluid buildup in the knee joint • An overload of the extensor mechanism of the knee with or without malalignment of the patella You may feel pain after exercising or when you sit too long. The pain may be a nagging ache or an occasional sharp twinge. Because the pain is around the front of your knee, treatment has traditionally focused on the knee itself and may include taping or bracing the kneecap, or patel- la, and/ or strengthening the thigh muscle—the quadriceps—that helps control your kneecap to improve the contact area between the kneecap and the thigh bone, or femur, beneath it. Howev- er, recent evidence suggests that strengthening your hip and core muscles can also help. The control of your knee from side to side comes from the glutes and core control; that is why those areas are so important in management of anterior knee pain. The exercises below will work on a combination of flexibility and strength of your knee, hip, and core. Although some soreness with exercise is expected, we do not want any sharp pain–pain that gets worse with each rep of an exercise or any increased soreness for more than 24 hours.

It is a guide to help patients manage leg swelling with bandages. It is only to be used after the patient has been taught bandaging by a clinician at the Cancer Rehabilitation and Survivorship (CRS) Clinic at Princess Margaret Cancer Centre. Do not self-bandage if you have an infection in your abdomen, leg(s) or feet. Signs of an infection may include: • Swelling in these areas and redness of the skin (this redness can quickly spread) • Pain in your leg(s) or feet • Tenderness and/or warmth in your leg(s) or feet • Fever, chills or feeling unwell If you have an infection or think you have an infection, go to: • Your Family Doctor • Walk-in Clinic • Urgent Care Clinic If no Walk-in clinic is open, go to the closest hospital Emergency Department. 2 What is the lymphatic system? Your lymphatic system removes extra fluid and waste from your body. It plays an important role in how your immune system works. Your lymphatic system is made up of lymph nodes that are linked by lymph vessels. Your lymph nodes are bean-shaped organs that are found all over your body.

  • Getting a Leg up on Land
    GETTING A LEG UP in the almost four billion years since life on earth oozed into existence, evolution has generated some marvelous metamorphoses. One of the most spectacular is surely that which produced terrestrial creatures ON bearing limbs, fingers and toes from water-bound fish with fins. Today this group, the tetrapods, encompasses everything from birds and their dinosaur ancestors to lizards, snakes, turtles, frogs and mammals, in- cluding us. Some of these animals have modified or lost their limbs, but their common ancestor had them—two in front and two in back, where LAND fins once flicked instead. Recent fossil discoveries cast The replacement of fins with limbs was a crucial step in this transfor- mation, but it was by no means the only one. As tetrapods ventured onto light on the evolution of shore, they encountered challenges that no vertebrate had ever faced be- four-limbed animals from fish fore—it was not just a matter of developing legs and walking away. Land is a radically different medium from water, and to conquer it, tetrapods BY JENNIFER A. CLACK had to evolve novel ways to breathe, hear, and contend with gravity—the list goes on. Once this extreme makeover reached completion, however, the land was theirs to exploit. Until about 15 years ago, paleontologists understood very little about the sequence of events that made up the transition from fish to tetrapod. We knew that tetrapods had evolved from fish with fleshy fins akin to today’s lungfish and coelacanth, a relation first proposed by American paleontologist Edward D.
