Osteoma Osteoide de falange. Reporte de cinco casos y revisión bibliográfica

Introduction: Osteoid osteomas are rarely found in the phalanges. The purpose of this study is to report 5 cases with histologic diagnosis of phalanx osteoid osteoma and highlight the most important aspects of its diagnosis and treatment. Materials and Methods: A descriptive, retrospective study was conducted. Evaluation included pain level using the visual analog scale (VAS), active range of motion, and QuickDASH score before surgery and at final follow-up (mean, 35.4 months). Results: The mean time from first consultation to diagnosis was 10.6 months (range, 5-16 months). The mean preoperative QuickDASH score was 22.72 (range, 6.8-40.9). At last follow-up (mean, 35.4 months; range, 17-63), all patients were satisfied with the outcome. The mean VAS score for pain was 0. The mean QuickDASH score was 0. Conclusions: Osteoid osteoma should be considered in the differential diagnosis when patients complain of subacute or chronic digital pain that improves with NSAIDs. Surgical treatment by simple curettage or en bloc resection shows satisfactory results. However, due to its low prevalence, osteoid osteoma is commonly underdiagnosed resulting in diagnosis and treatment delays. Key words: Osteoid osteoma; phalanx; finger; chronic pain; swelling.
