What is fish mouth amputation?
What is fish mouth amputation?
The first step in a transmetatarsal amputation (TMA) is to make a curved fish-mouth incision just proximal to the infected tissue of the foot (see the image below). The incision runs from the midshaft of the fifth metatarsal laterally to the midshaft of the first metatarsal medially through a midplane axis.
What causes transfemoral amputation?
It is believed that 60% of vascular amputations are preventable. The leading causes of transfemoral amputation are complications from diabetes, such as peripheral vascular disease, open wounds, and infection.
What is Ertl procedure?
The Ertl technique, an osteomyoplastic procedure for transtibial amputation, can be used to create a highly functional residual limb. Creation of a tibiofibular bone bridge provides a stable, broad tibiofibular articulation that may be capable of some distal weight bearing.
How does a transfemoral prosthetic work?
A trans-femoral prosthesis is an artificial limb that replaces any amputated limb above the knee. The prosthesis is made from a high-quality raw material known as polypropylene. It has several components which fit together to construct the final piece.
What is the minimum height for below knee amputation (BKA)?
Ng et al. JAAOS 2010 Below Knee Amputation •Most common •Longer is better –Always? –Soft tissue •Minimum to utilize BKA prosthesis –2.5 cm per 30cm pt height –5cm distal to the tubercle Below Knee Amputation: Techniques
What is the surgical approach to a BKA?
Surgical approach for a BKA: Incisions: straight transverse anterior at level of expected bone cut—extend distally medial/lateral posterior to equator—through skin, SQ, fascia. Distal posterior—straight transverse at calculated level—through skin, SQ, fascia. Medially isolate saphenous vein and nerve.
How do you cut the tibia and fibula for amputation?
Cut the tibia with a power saw under saline irrigation; cut fibula 1 to 2 cm shorter. Use a bone hook to control the tibia and use an amputation knife on posterior surface. Directly on back of tibia and fibula—complete amputation, remove foot and distal tibia.
How many patients fail in through-knee amputation?
Healing rate and functional results in seventy-seven patients Failures in through-knee amputation. Disarticulation of the knee. A modified technique. A modified Gritti-Stokes amputation: its place in the management of peripheral vascular disease. Knee disarticulation versus above-knee amputation. Disarticulation of the knee. A modified technique.
