Description
Summary:Osteoid osteoma accounts for 5% of bone tumours. Uncommon in the foot, although with predisposition for the talus. Retrospective review of four cases of osteoid osteoma in the foot and ankle with focus on investigation and management. Equal male to female ratio. Mean age of 29.5 (±21.3). Nocturnal pain was present in 100% of cases. Three patients have had definitive treatment with resection. Mean time to diagnosis was 67 weeks (±65), and to treatment 46 weeks (±35). Diagnosis was established on imaging and histology, with sizes from 6mm to 15mm. The mean pre intervention Foot and Ankle Outcome Scores was 45%, improved to post intervention of 97%. Mean follow up time 17.6 months (±16). Osteoid osteomas are a challenging diagnosis. Remains an important differential in longstanding foot pain with minimal or no history of trauma. Treatment options include ablation or surgical resection. IV.
