Foot ulcers are super easy:
Arterial wound (bad/no pulses, cool/cold foot) = send for Vascular consult
Venous wound (swelling, medial ankle often) = compress, bit of debride
Pressure (plantar foot, bedsore, or other rub point) = offload
Trauma/infected = debride, irrigate, abx, amputation
Offloading "biomechanics" plantar foot wounds is really simple. It's fairly subjective but very easy. It's typically met heads or heel or tufts of toes or other weightbear areas. You simply move the pressure to behind or beside the pressure bruise/wound area. That is usually custom insoles/boot Rx or initial quick fix with padding felt/etc around area and/or cut out pressured area. Get a good relationship with local orthotist shops and get some 1/4" felt roll or pre-cut pads and go at it. GL
