Power lawnmower injuries

Primary closure of lawn mower injuries to the foot: a case series

The standard initial treatment of lawn mower injuries to the foot consists of prompt administration of parenteral antibiotics, debridement of devitalized tissue, irrigation, repair of traumatized vascular structures, and stabilization of osseous fractures. The primary closure of these wounds at the initial operation is a controversial concept. The authors performed a retrospective study of 9 lawn mower injuries in which primary closure was performed. Medical records were evaluated, and 7 patients were reached for follow-up interviews. The hospital courses for this patient population were remarkably lower than those previously reported in the literature. No patient required further admission to the hospital or surgical intervention. The postinjury functional evaluation mean score was 97.6%. The results demonstrate that this treatment method can be an effective means for treating this mutilating injury in the foot.

Lawnmower injuries in children

OBJECTIVE

Power lawnmowers can pose significant danger of injury to both the operator and the bystander, from direct contact with the rotary blades or missile injury. Our objective was to review our experience with paediatric lawnmower-associated trauma, and the safety recommendations available to operators of power lawnmowers.

METHODS

The patient cohort comprised paediatric (<16 years of age) patients treated for lawnmower-associated trauma, by the plastic surgery service, between 1996 and 2003. These patients were identified retrospectively. Age at the time of injury, location and extent of bony and soft tissue injuries sustained, treatment instituted and clinical outcome were recorded. Brochures and instruction manuals of six lawnmower manufacturers were reviewed, and safety recommendations noted.

RESULTS

Fifteen patients were identified. The majority of injuries occurred from direct contact with the rotary blades (93%); the remaining child sustained a burn injury. Fourteen children (93%) required operative intervention. Seven patients (46%) sustained injuries resulting in amputation, two of whom had major limb amputations. All children, except the burns patient, underwent wound debridement and received antibiotic therapy. Reconstructive methods ranged from primary closure to free tissue transfer. Many patients required multiple procedures. In all instruction manuals, instructions to keep children and pets indoors or out of the yard when mowing were found.

CONCLUSIONS

Lawnmower injuries can be devastating, particularly in children. Many victims have lasting deformities as a result of their injuries. Awareness of and stringent adherence to safety precautions during use of power lawnmowers can prevent many of these accidents.

Lawnmower injuries in children: a 10-year experience

Approximately 77,800 annual lawnmower-related injuries are treated in the USA, with 9,300 involving children. This work reviews the literature and reports our 10-year experience with lawnmower injuries. We retrospectively reviewed patients with lawnmower injuries admitted to the Women and Children's Hospital of Buffalo from 1995 to 2005 and reviewed the literature. Sixteen patients with mower-related injuries were admitted to our institution, with three due to walk-behind mowers and 13 due to riding mowers. The mean age was 7.5 years. Riding mower injuries had a higher average injury severity score (14.3 vs. 9) and a longer average length of hospital stay (15 vs. 2 days). All of the walk-behind mower injuries were extremity injuries, with two requiring amputations. Eleven of the riding mower injuries had extremity injuries alone, one had isolated torso injuries, and one had both extremity and torso injuries. Three required amputations, and the two patients with torso injuries required extensive surgical reconstructions. Pediatric lawnmower injuries, particularly due to riding mowers, are a highly preventable cause of morbidity and mortality. Increased public safety awareness and further manufacturer safety modifications should be strongly encouraged in order to limit this cause of pediatric trauma.
