Heterotopic ossification (HO) is a common complication after elbow trauma and can cause severe upper limb disability. Although multiple prognostic factors have been reported to be associated with the development of post-traumatic HO, no model has yet been able to combine these predictors more succinctly to convey prognostic information and medical measures to patients. Therefore, this study aimed to identify prognostic factors leading to the formation of HO after surgery for elbow trauma, and to establish and validate a nomogram to predict the probability of HO formation in such particular injuries.

肘部创伤后异位骨化形成的新预后列线图：上海创伤后肘部异位骨化预测（STEHOP）模型。

异位骨化（HO）是肘部创伤后常见的并发症，可导致严重的上肢残疾。尽管据报道多种预后因素与创伤后 HO 的发展有关，但尚无模型能够更简洁地结合这些预测因素来向患者传达预后信息和医疗措施。因此，本研究旨在确定导致肘部创伤手术后形成 HO 的预后因素，并建立和验证列线图来预测此类特定损伤中形成 HO 的概率。
