Occasionally following major trauma a primary amputation is preferable. This would be the case in an open fracture with major distal neurovascular compromise and other more life threatening injuries are present. Vascular surgery • The first two categories are the most prevalent. • Diabetic foot sepsis is often a major cause of sepsis which can spread rapidly in the presence of established peripheral vascular disease. • As a general rule the main issue in vascular surgery is to optimise vascular inflow prior to surgery. The more distal the planned amputation is to be, the more important this rule becomes. otherwiseit will bemajor threat to like
• In other situations there has been something such as an embolic event that has not been revascularised in time. In this case the limb shows fixed mottling and an amputation will be needed. Types of amputations As the vast majority of commonly performed amputations affect the lower limbs these will be covered here. The main categories of amputations are: • Pelvic disarticulation (hindquarter) • Above knee amputation • Gritti Stokes (through knee amputation) • Below knee amputation (using either Skew or Burgess flaps) • Syme's amputation (through ankle) • Amputations of mid foot and digits Choosing a level of amputation depends on: • The disease process being treated • Desired functional outcome • Co-morbidities of the patient Above knee amputations • Quick to perform • Heal reliably • Patients regain their general health quickly • For this benefit, a functional price has to be paid and many patients over the age of 70 will never walk on an above knee prosthesis. • Above knee amputations use equal anterior-posterior flaps Below knee amputations • Technically more challenging to perform • Heal less reliably than their above knee counterparts. • However, many more patients are able to walk using a below knee prosthesis. • In below knee amputations the two main flaps are Skew flaps or the Burgess Long posterior flap. Skew flaps result in a less bulky limb that is easier to attach a prosthesis to. It is worth remembering that whilst it may be technically feasible to offer a below knee amputation there may be circumstances where an above knee option is preferable. For example, in fixed flexion deformities of the lower limb, little functional benefit would be gained from below knee amputation surgery. Question 1-3 Theme: Amputations A.
