BACKGROUND
Heterotopic ossification (HO) refers to the formation of new bone in non-skeletal tissues such as muscles, tendons or other soft tissues. Severe muscle and soft tissue injury often lead to the formation of HO. However, anterior HO of the ankle is rarely reported.
CASE SUMMARY
We report a patient with massive HO in front of the ankle joint for 23 years. In 1998, the patient was injured by a falling object on the right lower extremity, which gradually formed a massive heterotopic bone change in the right calf and dorsum of the foot. The patient did not develop gradual ankle function limitations until nearly 36 mo ago, and underwent resection of HO. Even after 23 years and resection of HO, the ankle joint was still able to move.
CONCLUSION
It is recommended that the orthopedist should be aware of HO and distinguish it from bone tumor.
背景
异位骨化（HO）是指在肌肉、肌腱或其他软组织等非骨骼组织中形成新骨。严重的肌肉和软组织损伤常导致HO形成。然而，踝关节前方的HO鲜有报道。
病例摘要
我们报告1例踝关节前方存在巨大HO达23年的患者。1998年，该患者右下肢被重物砸伤，右小腿和足背逐渐形成巨大的异位骨改变。直到近36个月前患者才逐渐出现踝关节功能受限，并接受了HO切除术。即使在23年且进行HO切除术后，踝关节仍能活动。
结论
建议骨科医生应了解HO并将其与骨肿瘤相鉴别。
