To determine how often os trigonum is accompanied by accessory navicular and os peroneum. A secondary aim of the study was to investigate the bone and related tendon pathologies that may develop in these three accessory bones.
A total of 110 patients who were evaluated by ankle MRI and were determined with os trigonum between 2009-2015 were included in the study. The frequency was determined of os trigonum together with accessory navicular bone and os peroneum. MR images were also evaluated in respect of bone pathologies and related tendon pathologies of these 3 accessory bones.
Of 110 patients determined with os trigonum on MRI, 21 (19%) were also determined with accessory navicular bone and 5 (4.5%) with os peroneum.When bone pathologies were examined, the most frequently seen pathology was bone marrow edema.The most common pathology in the tendons related to the accessory bones was increased amount of synovial fluid within the tendon sheath. In cases with os trigonum, bone changes were observed more frequently than pathologies of the adjacent tendons, in the accessory navicular bone cases, tendon pathologies were observed more than bone changes and in the cases with os peroneum, bone and tendon pathologies were determined at equal rates.There was no significant difference in terms of FHL tendon pathology between patients with and without edema in os trigonum. However, TP tendon was significantly more pathological in patients with edema in accessory navicular bone.
More than one accessory bone was determined in approximately one in four cases.The most common pathologies determined in these accessory bones was bone marrow edema and increased amount of synovial fluid within the tendon sheath.It is necessary to investigate and report all these findings on MRI as they play an important role in the explanation of clinical findings and treatment planning.
确定距骨后三角骨与副舟骨和外踝副骨同时存在的频率。本研究的次要目的是研究这三个副骨可能发生的骨和相关肌腱病变。
本研究共纳入 2009 年至 2015 年间通过踝关节 MRI 评估并确诊为距骨后三角骨的 110 例患者。确定距骨后三角骨同时存在副舟骨和外踝副骨的频率。还评估了这些 3 个副骨的骨骼病变和相关肌腱病变的 MR 图像。
在 110 例通过 MRI 确定距骨后三角骨的患者中，21 例（19%）还确定存在副舟骨，5 例（4.5%）存在外踝副骨。检查骨骼病变时，最常见的病变是骨髓水肿。与副骨相关的肌腱中最常见的病变是腱鞘内滑液量增加。在距骨后三角骨病例中，观察到骨改变比相邻肌腱的病变更常见，在副舟骨病例中，观察到肌腱病变比骨改变更常见，在外踝副骨病例中，骨和肌腱病变的发生率相等。在距骨后三角骨有水肿的患者中，FHL 肌腱病变与无水肿的患者无显著差异。然而，在有副舟骨水肿的患者中，TP 肌腱的病变明显更多。
大约四分之一的病例存在不止一个副骨。这些副骨最常见的病变是骨髓水肿和腱鞘内滑液量增加。在 MRI 上有必要检查和报告所有这些发现，因为它们在解释临床发现和治疗计划中起着重要作用。
