Purpose. To examine the management and outcome of patients suffering complex paediatric lower limb injuries with bone and soft tissue loss. Method. A retrospective review was conducted identifying patients from our trauma database. Inclusion criteria were age (4–17 years) and open lower-limb trauma. Outcome measures included time to soft tissue coverage, surgical techniques, trauma impact scores, health-related quality of life, union and complication rates. Results. We identified 26 patients. 24 patients had open tibia fractures including 10 patients with bone loss. In 9 patients primary skin closure was achieved by acute shortening. 17 patients required soft tissue coverage including 14 free vascularised muscle flaps (89% within 48 hours). The surgical techniques applied were: circular fine wire frame (16), external fixateur (5) and open reduction internal fixation (5). Median follow up time was 8 (3–45) months. The trauma impact scores showed one in three patients were at risk of
