We report the management of a pathological fracture through a proximal tibial non-ossifying fibroma (NOF) in a 13-year-old girl with neurofibromatosis type 1 (NF1). The fracture was minimally displaced, and the lesion had clinical features of a NOF, and therefore biopsy was not required. Operative fixation has been the preferred method of treatment for pathological fractures through NOF associated with NF1. Multiple NOFs associated with NF1 are rare but can coalesce resulting in large lesions with an increased risk of pathological fracture. In cases which permit, non-operative treatment with cast immobilisation can yield satisfactory results.
