A Case Report on Symptomatic Therapy Solitary Osteochondroma of Left Distal Femur

Osteochondroma is a benign bone tumor that develops near the growth plate, commonly during childhood or adolescence. It can be solitary or multiple, with genetic mutations in EXT1 and EXT2 genes playing a significant role in its development. This case report presents a 22-year-old male with a two-year history of pain and swelling in the left digital femur, which worsened over two months, causing mobility issues unresponsive to medication and physiotherapy. Examination revealed a hard, immobile, osseous mass with intact skin, and imaging confirmed a sessile osteochondroma with mild joint effusion and ligamentous involvement. Surgical excision was performed successfully, and post-operative recovery was uneventful, with significant symptom relief within 48 hours. The patient was discharged on appropriate medication and experienced complete functional improvement at follow-up. This case highlights the importance of early diagnosis, imaging, and surgical intervention in symptomatic osteochondroma for optimal outcomes.
