title: Amputations and prosthetics.
abstract: The author presents in a condensed way an overview of the principles of limb amputations and further treatment of patients who underwent such a procedure. The metabolic cost of walking, load transfer, and wound healing are reviewed in a concise manner. Particular attention is given to blood supply to the wound and methods to determine adequate perfusion with a clear analysis of the pro and cons of the Doppler method. Pediatric amputations, because of their specificity, are considered apart. Disarticulation of limbs is the method of choice in children, because of it retains growth potential of the bone and prevents bony overgrowth of the stump. The article discusses the main indications for limb amputations: trauma, peripheral vascular disease, musculoskeletal tumors and gas gangrene. In every case the specificity of the amputation is considered by the author. Postoperative care is also presented, with a short description of possible complications. Pain is the most common and treatment strategies should be similar to those used in treating patients with major reflex sympathetic causalgia. Edema, joint contracture, wound failure and dermatologic problems are all shortly reviewed. The last part of the article treats with the principles of prosthetics in both the upper and lower limb. These principles are presented basing on the level of amputation: for the upper limb hand, transradial, transhumeral amputations and shoulder disarticulation. For the lower limb foot and ankle, transtibial and transfemoral amputations are considered.
