A male patient on maintenance dialysis in his 70s was diagnosed with a left metatarsal subcallous ulcer and treated at a dermatology department in April 20XX, but it did not improve and intervention was requested by a certified diabetes nurse in October. The ankle-brachial index was 1.02 on the right and 1.00 on the left, skin perfusion pressure of the dorsum of the foot was 130 mmHg on the right and 78 mmHg on the left, and foot deformation due to sensory and motor neuropathies had occurred. Considering that review of the footwear is necessary, the foot was re-evaluated in cooperation with a physical therapist. Gait observation suggested an increase in load stress on the left callous region. To reduce the pressure on the left callous region by making the left foot pressure locus pass through the medial side of the sole during walking and promoting kicking out while securing stability in the left stance phase, simple footwear using a pad was prepared. The subcallous ulcer had healed one year after intervention. While the importance of foot care has become known, the insufficient involvement of physical therapists has been pointed out. Cooperation between a certified nurse and physical therapist led to effective treatment even in a moderate-scale hospital with insufficient equipment. Treatment and care of the feet is a medical care field requiring intervention by many professionals and much knowledge. Nurses who have many occasions to observe patients’ feet need to cooperate with professionals considering their specialties when carrying out their role of nurses.
