The purpose of this study was to determine whether sonography is as accurate as magnetic resonance (MR) imaging for depicting abnormalities of the spring ligament in patients with symptomatic posterior tibial tendon (PTT) dysfunction.
Sixteen patients (18 ligaments) with symptomatic PTT dysfunction were prospectively evaluated with sonography and MR imaging.
Magnetic resonance imaging showed spring ligament tears in 8 of 18 feet, including 6 incomplete tears and 2 complete tears. Sonography showed spring ligament tears in 7 of 18 feet, including 6 incomplete tears and 1 complete tear. The findings of sonography and MR imaging were concordant in 17 of 18 feet (94%). Six of the 8 spring ligament tears on MR imaging were associated with posterior tibial tendinosis or tears.
Sonography is an effective imaging option in assessing spring ligament abnormalities in patients with symptomatic PTT dysfunction.
本研究旨在确定超声检查在描绘有症状的胫后肌腱（PTT）功能障碍患者的弹簧韧带异常方面是否与磁共振（MR）成像一样准确。
对16例有症状的PTT功能障碍患者（18条韧带）进行了超声检查和MR成像的前瞻性评估。
MR成像显示18只足中的8只存在弹簧韧带撕裂，其中6例为不完全撕裂，2例为完全撕裂。超声检查显示18只足中的7只存在弹簧韧带撕裂，其中6例为不完全撕裂，1例为完全撕裂。超声检查和MR成像的结果在18只足中的17只（94%）中一致。MR成像上8例弹簧韧带撕裂中有6例与胫后肌腱病或撕裂相关。
超声检查是评估有症状的PTT功能障碍患者弹簧韧带异常的一种有效影像学方法。
