Seventy consecutive patients treated for lawn mower injuries to the foot and ankle were reviewed to determine optimal treatment, functional results, and complications. Injuries were classified into 1 or more functional-anatomical zones (I, digits; II, dorsum; III, plantar nonweight-bearing surface; IV, heel; and V, ankle) for a total of 96 injuries. Thirty-one patients were available for follow-up. Mean age was 36.7 years and 84% were males. Most injuries (67%) involved patients > 16 years old using a push mower; however, 18% involved children < 5 years old, usually caused by riding mowers (70%). Primary closure after adequate irrigation and debridement was the preferred method of treatment except in patients with Zone IV injuries. Antibiotic prophylaxis was used in almost all injuries (93%). A 100% ambulation rate was achieved with 10% of patients requiring a prosthesis. Zone IV (heel) injuries had a 50% complication rate from chronic soft tissue breakdown. The wound infection rate per injury was 12.5% and did not vary significantly between closed (11.4%) and open (17.6%) treatment. Lawn mower injuries to the foot and ankle can be closed primarily after adequate irrigation and debridement without compromise of infection rate or function. Antibiotic prophylaxis is recommended. One-sixth of these injuries involve children < 5 years of age and can be prevented.
