Introduction Heterotopic ossification is the formation of lamellar bone in periarticular soft tissue that can be seen in paralysed patients or following trauma. It can cause significant burden to already debilitated patients. Case presentation A 12-year-old boy with paraplegia due to neuromyelitis optica presented with progressive right knee pain and swelling. There was no history of trauma to the knee. Anteroposterior radiograph of femur at the initial presentation showed a supracondylar femur fracture for which casting was performed. Six weeks later, when casting was removed, swelling along with increased rubor in distal thigh region was noted. Radiography of the right femur revealed an unhealed distal femur fracture along with massive ossification extending from lesser trochanter to fracture line along the soft tissue around the femoral shaft. Conclusion This case presented the clinical and imaging findings of a giant heterotopic ossification in the thigh region following an extra-articular fracture.
引言 异位骨化是指在关节周围软组织中形成板层骨，可在瘫痪患者或创伤后出现。它会给本已虚弱的患者带来巨大负担。病例报告 一名因视神经脊髓炎导致截瘫的12岁男孩，出现右膝进行性疼痛和肿胀。无膝关节外伤史。初次就诊时股骨前后位X线片显示股骨髁上骨折，予以石膏固定。六周后拆除石膏时，发现大腿远端肿胀且发红加重。右股骨X线检查显示股骨远端骨折未愈合，同时有大量骨化，从股骨小转子沿股骨干周围软组织延伸至骨折线。结论 该病例呈现了关节外骨折后大腿区域巨大异位骨化的临床及影像学表现。
