femur replacement prosthesis ..

Background and purpose The methods of reconstruction for proximal femur bone tumors that are used most often include modular prosthetic replacement and allograft-prosthesis composite reconstruction. In modular prostheses, the abductors are detached from the insertion and then reinserted into the implant, and the iliopsoas is detached and left free. In the allograft-prosthesis composite, the detached tendons are fixated to the graft. We assessed whether the latter procedure provides functional advantages regarding gait. Patients and methods We studied 2 groups of 10 patients, each with prosthetic reconstruction of the proximal femur either with modular prosthetic replacement or with allograft-prosthesis composite. Functional performance was analyzed by gait analysis 2.5-10 years after surgery. At that time, all the patients had good function according to the Musculoskeletal Society score. Results Walking speed was reduced in all patients, and especially in patients with modular prosthetic replacement. Different hip extension patterns during late stance were found in the 2 groups. Surface EMG showed a typical prolonged muscle co-contraction pattern during gait, which was more evident in modular prosthetic patients. Interpretation Although both procedures provided good functional outcome in the long-term follow-up, gait analysis revealed mechanical changes during gait that were probably related to the muscle reinsertion procedure. Direct fixation of the muscles to the bone graft appeared to result in a more efficient muscular recovery.

Your full recovery from your total hip replacement surgery is going to take several months. This pamphlet will help you understand your recovery. Guidelines are included which discuss precautions to protect your new joint, exercises that increase you hip strength, and activities of daily living that will help you become an active partner in your care and recovery.

There are two main types of artificial knee replacement prosthesis—cemented and uncemented. Both types are widely used. In many cases, a combination of the two types are used. The kneecap, or patellar, part of the prosthesis is usually cemented into place. The choice to use a cemented or uncemented prosthesis is usually made by the surgeon based on your age and lifestyle, and your surgeon’s experience.

A metal socket with a strong plastic lining is put into your hipbone. Then the ball portion of your thighbone is replaced with a metal prosthesis that fits in the metal socket. This prosthesis is a long metal stem with a metal ball on the end. The stem is placed firmly inside the thighbone. After both pieces are in place, an x-ray is made of your new hip joint to make sure it is in the correct position. Your incision will be closed with stitches or staples. Then you will be taken to the recovery room.

Disassembly of a Distal Femur Modular Prosthesis After Tumor Resection

In a transtibial amputation, the fibula is transected 1 to 2 cm shorter than the tibia to avoid distal fibula pain. If the fibula is transected at the same length as the tibia, the patient senses that the fibula is too long, which may cause pain over the distal fibula. If the fibula is cut too short, a more conical shape, rather than the desired cylindrical – shape residual limb results. The cylindrical shape is better suited for total contact prosthetic fitting techniques. A bevel is placed on the anterior distal tibia to minimize tibial pain on weight bearing. To avoid a painful neuroma, a collection of axons and fibrous tissue, nerves should be identified, drawn down, severed, and allowed to retract at least 3 to 5 cm away from the areas of weight-bearing pressure.

Although your clinician will be caring and thoughtful, nothing replaces talking to a fellow amputee. A “Peer Mentor” or “Peer Visitor” is an amputee that will be available to speak with you about your worries and concerns. They can truly understand and relate to the challenges and fears of our amputee patients and will make themselves available to meet you in our office or your home to discuss those issues that are on your mind. They can answer questions, offer support and be a trusting friend when you need them most. After all, many of them have experienced similar feelings and will be a valuable asset to aide in your recovery.

The femoral component is then fitted on the femur. In the uncemented type of femoral component, the prosthesis is held on the end of the bone because the end of bone has a taperd cut. The metal prosthesis is made to almost exactly match the taperd cut of the bone. Fitting the femoral component onto the end of the bone holds the component in place by friction. In the cemented component, an epoxy cement is used to attach the metal prosthesis to the bone.

In recent years many patients have been treated with a minimally invasive total hip replacement. The primary difference between minimally invasive and conventional approaches is how the surgeon exposes and gains access to the hip joint. With the conventional approach, the incision is 10-16 inches long, whereas minimally invasive incisions are one or two small incisions about 4 inches long; one incision is for the acetabular component and one is for the femoral component. Also, the minimally invasive approach involves splitting and dividing muscles instead of cutting them. Minimally invasive joint replacement is less traumatic, promotes better healing and the joint regains stability more quickly. There is less blood loss and the patient can sometimes go home the same day. With the convention method, there are several different approaches used to make the incision, usually based on your surgeon’s training and preferences.

At the age of 14, John from Catcott in Somerset had his left leg amputated through the hip after a tumour was found in his femur. Early into his recovery he was fitted with what he describes as a crude but functional prosthesis, which had a fixed hip joint with button release to allow sitting and elastic bands which controlled the knee deflection when walking.

The day after your surgery, the physical therapist will get you out of bed for the first time. The therapist will help you walk with a walker or crutches as you are able. You will be sitting in a chair for 15 to 30 minutes by the second day. Each day the amount of walking and time sitting in the chair will increase as you can tolerate. Before you go home the physical therapist will teach you how to climb stairs safely to protect your new knee. Your physical therapist will start you on a home exercise program on the second day after your knee surgery. Additionally you may perform isometric exercises in bed right after your surgery to help you begin to recover.
