Diabetes

Toe Amputations

• Indications

• Infection in IP joints

• Osteomyelitis

• Non-healing ulcer is NOT an

indication

• Gangrene with restored

perfusion

• Localized gangrene (emboli)

• Deformities in lesser toes

Exarticulations

•Never in IP joints

•Remove cartilage in MTP

joints

•=Transmetatarsal

amputation

Joint Resection

•MTP Joints

• Infection

• Infection control

•Off-loading

•Plantar approach

•Resect cartilage on proximal

phalanx

Transmetatarsal amputations

•Single rays

• From medial side

- Up to two

• From lateral side

- Up to three

•Forefoot amputation

Chopard amputation

•Short stump

•High pressure

•Rotational forces

Symes Amputation

•Shortening

•High Pressure

•Rotational forces

•Fat pad displacement

Tissue Defects

• Definition of a diabetic foot ulcer:

• ”A defect of the skin on a foot in a person with diabetes”

• The ”beginning”

• The ”end”

How Long to Heal a Diabetic Foot Ulcer?

Tenotomy Results

Consider Tenotomy

•Ulcer at pulpa

•Ulcer at dorsal PIP

•Nail changes

•Callus formation at tip of

toes

•Be aware of transfer

pressure

Achilles Tendon Lengthening

•High healing rates of

forefoot ulcers (91%)

•Transfer ulcers at heel

(15%)

•This lead to a pause in using

this procedure

• It is re-introduced due to a

change of procedure (from

percutaneous to open

technique)
