To study the inducement and location of diabetes foot ulcer, it provide a basis for the prevention and control of diabetes foot.

Data of 230 inpatients with diabetic foot admitted to wound Repair Center of Liyuan Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology from January 2019 to September 2021 were retrospectively analyzed. Collected the information includes the patient′s gender, age, place of residence, underlying diseases, whether other diseases were present at the time of onset, the cause and location of foot ulcers, and risk factors. Data were compared by χ² test and Kruskal-Wallis H test.

(1) 112 cases of foot ulcer caused by daily life and health care behavior, accounting for 48.70% of the total number; there were 69 cases of ulcers without obvious inducements, accounting for 30.00%; 49 cases (21.30%) were caused by itching, dry chapped skin, edema, corns and other complications. Foot ulcers in 178 cases were recurrent, accounted for 77.39%, in which 98 cases caused by inadequate health and daily life behavior, accounting for 42.61%. The inducement of foot ulcers had a greater impact on recurrence than initial onset, the difference was statistically significant (χ²=12.759, P< 0.05). (2) Among the 230 patients with diabetic foot ulcer, 119 cases (51.74%) of the patients with recurrent ulcer were the dorsum of the foot, followed by 40 cases (17.39%) of the plantar, 19 cases (8.26%) of the dorsum and plantar. The majority of patients with recurrent ulcers suffered from the dorsum of the foot, there was statistically significant difference in the location of onset between initial and recurrent ulcers (χ²=12.349, P< 0.05). (3) 112 cases were caused by inappropriate daily life and health care behavior, and 77 cases (33.48%) occurred in the dorsum of the foot. Compared different ulcer site with incentive, the difference was statistically significant (χ²=25.934, P<0.001). (4)198 cases (86.09%) of ulcers occurred on the forefoot, followed by 21 cases (9.13%) of the hind foot, 8 cases (3.48%) in two or more areas, only 3 cases of patients′ ulcers occurred in the midfoot, accounting for 1.30%. Comparing the incidence site and location of ulcers, ulcers often occured at the dorsum of the forefoot, with a statistically significant difference (χ²=23.530, P<0.05).

Diabetes foot ulcer is more recurrent, the recurrence of diabetes foot ulcer is mostly located in the forefoot, and the dorsum of the foot is more than the sole of the foot. The inducement of recurrence is mostly inappropriate daily life and health care behavior, which provides a basis for the prevention of diabetes foot recurrence.
