Intra-medullary osteosclerosis of the tibia in children

The objective of this study was to assess paediatric patients with intra-medullary osteosclerosis to determine whether the first visit provides sufficient information to establish the diagnosis and rule out both osteoid osteoma and stress fracture, whether a biopsy is required, and which treatment is optimal.HypothesisThe diagnosis of intra-medullary osteosclerosis of the tibia can be made at the first visit.Patients and methodsSeven paediatric patients, 4 males and 3 females, with a mean age of 11 years, were included in this retrospective study. We evaluated the clinical features, findings from imaging studies (standard radiographs, computed tomography, magnetic resonance imaging, and bone scintigraphy), and treatment outcomes.ResultsAt the first visit, all patients had a painful swelling at the middle of the shin and imaging study evidence of antero-lateral tibial cortical thickening extending into the medullary cavity; in 5 patients, a linear lucency was visible. No other bone abnormalities were seen. Treatments included non-operative measures, pinning, and nailing. None of these treatments provided permanent bone healing or pain relief, although transitory freedom from pain with or without radiological bone healing was achieved.DiscussionIntra-medullary osteosclerosis of the tibia is rarely reported and therefore probably underdiagnosed. Distinctive characteristics of the cortical and endosteal thickening include location at the antero-lateral mid-diaphysis and, in some ...
