This study assesses whether a correlation exists between the shape of the medial longitudinal arch of the foot measured on weight-bearing radiographs and risk for peroneus longus and brevis pathology.
After institutional approval, a retrospective search was conducted for patients who presented between 2017 and 2023 with foot and ankle pain, and for whom ankle MRIs and weight-bearing ankle radiographs were performed within 6 months of each other. One hundred forty-one cases of peroneal tendon dysfunction that met the criteria were identified. Talonavicular uncoverage angle, Meary's angle, calcaneal pitch, cuneiform-to-fifth metatarsal height, and Djian-Annonier's (DA) angle were calculated on weight-bearing ankle radiographs. MRI was used to assess the peroneus brevis tendon, peroneus longus tendon, common peroneal tendon sheath, and the peroneus brevis and longus tendon sheaths. Associations between radiographic angles and MRI findings were explored through one-way ANOVA followed by Tukey's HSD method for multiple comparisons.
Significant differences between patients with normal tendons or tendinosis versus tears of the peroneus brevis tendon were found using Meary's angle. The study also demonstrated statistically significant differences between the calcaneal pitch angle in patients with peroneus longus tenosynovitis vs normal peroneus longus tendon sheath.
This study demonstrated that Meary's angle and calcaneal pitch can assist in stratifying risk for peroneus brevis tendon tears and peroneus longus tenosynovitis, respectively.
本研究评估在负重X线片上测量的足内侧纵弓形状与腓骨长肌和腓骨短肌病变风险之间是否存在相关性。
经机构批准后，对2017年至2023年间出现足踝疼痛且在彼此6个月内进行了踝关节MRI和负重踝关节X线片检查的患者进行回顾性检索。确定了141例符合标准的腓骨肌腱功能障碍病例。在负重踝关节X线片上计算距舟关节覆盖角、梅里角、跟骨倾斜角、楔骨至第五跖骨高度以及吉安-阿诺尼耶（DA）角。MRI用于评估腓骨短肌腱、腓骨长肌腱、腓总腱鞘以及腓骨短肌和长肌的腱鞘。通过单因素方差分析，随后采用图基HSD方法进行多重比较，探讨影像学角度与MRI结果之间的关联。
使用梅里角发现，肌腱正常或肌腱病患者与腓骨短肌腱撕裂患者之间存在显著差异。该研究还表明，腓骨长肌腱鞘炎患者与正常腓骨长肌腱腱鞘患者的跟骨倾斜角存在统计学显著差异。
本研究表明，梅里角和跟骨倾斜角可分别有助于对腓骨短肌腱撕裂和腓骨长肌腱鞘炎的风险进行分层。
