Damn nuisanceDamn nuisance

Remaining the limb is more worse than Remaining the limb is more worse than having no limb at all …. Because ofhaving no limb at all …. Because of :- :-

1.1. Pain Pain 2.2. Gross malformation Gross malformation 3.3. Recurrent sepsisRecurrent sepsis4.4. Sever loss of function Sever loss of function

Varieties of amputationsVarieties of amputations

ProvisionalProvisional amputationamputation When primary healing is unlikely When primary healing is unlikely The limb amputate as distal as the causal The limb amputate as distal as the causal

factor will allow factor will allow Skin flap suture loosely over a pack Skin flap suture loosely over a pack Re-amputation perform when stump Re-amputation perform when stump

condition is favorable condition is favorable

Amputations Amputations at the sites of at the sites of election election

Page 11: orthopedocts.Amputation of extremities.(dr.omer barawe)

The The “ sites of election ”“ sites of election ” are are determined by :-determined by :-

1.1. the demand of the prosthetic design the demand of the prosthetic design 2.2. local function e.g bellow the most distal local function e.g bellow the most distal

palpable arterial pulsation palpable arterial pulsation

Too short a stumpToo short a stump slips out slips out from the prosthesis from the prosthesis

Too long a stumpToo long a stump painful , painful , ulcerate , complicates the incorporation of ulcerate , complicates the incorporation of the joint in the prosthesis the joint in the prosthesis

Now a day the skill of orthotiest make Now a day the skill of orthotiest make amputation possible at any level amputation possible at any level

Skin flaps are cut so that there combined Skin flaps are cut so that there combined length equals one & half the width of the length equals one & half the width of the limb at the site of the amputationlimb at the site of the amputation

Equal flaps are for upper limb & trans-Equal flaps are for upper limb & trans-femoral amputations , long posterior femoral amputations , long posterior flap for bellow – knee flap for bellow – knee

Muscle cut at distal level from the level of Muscle cut at distal level from the level of the bone proposed the bone proposed

MyoplastyMyoplasty …. When the muscles …. When the muscles sutured together over the bone sutured together over the bone
