a Radiograph following lawnmower injury and partial amputation of the leg in a 10.5-year-old male (Table 1, case 1). Subsequent deep infection developed following guillotine amputation and Ertl osteomyoplasty, performed within 24 h of injury, requiring debridement and removal of the bone bridge. b Immediate post-operative radiographs post-revision Ertl osteomyoplasty at 26 months after the initial injury for stump overgrowth, using iliac crest graft and attached periosteal sleeve. c Good bone bridge between tibia and fibula without overgrowth at the 36-month follow-up but asymptomatic genu varum (medial proximal tibial angle 83°). d Clinical appearance at follow-up shows healthy residual limb
