The spring ligament complex (SLC) is a static support of the head of the talus and a major anatomical contributor to the integrity of the medial longitudinal arch, particularly if the dynamic support of the posterior tibial tendon is compromised. For this reason, we sought to further elucidate the anatomical components and dimensions of this ligamentous complex.
Dissection was performed on 30 adult cadaver feet disarticulated at the ankle joint that were preserved by embalming technique.
The superomedial ligament (SML) averages 42.51 +/- 3.93 mm and 33.44 +/- 3.34 mm at the superomedial and inferolateral borders, respectively. The width at the level of sustentaculum tali and navicular tuberosity averaged 20.00 +/- 2.35 mm and 10.26 +/- 2.05 mm, respectively. The medioplantar oblique (MPO) ligament averaged 23.56 +/- 2.15 mm and 21.20 +/- 1.42 mm at the medial and the lateral borders, respectively. The widths at the navicular and calcaneal side were 2.71 +/- 0.39 mm and 8.14 +/- 0.56 mm, respectively. The inferoplantar longitudinal (IPL) ligament measured 4.26 +/- 0.43 mm and 2.66 +/- 0.42 mm at the medial and lateral borders, respectively. The width at the calcaneal and navicular insertions measured 5.21 +/- 0.53 mm and 3.39 +/- 0.39 mm, respectively.
The distinction between the SML and MPO components of the spring ligament complex is difficult. This study tried to clarify the dimensions and configurations of these components of the SLC.
This effort may aid surgeons who wish to repair this ligament with more precision.
弹簧韧带复合体（SLC）是距骨头的静态支撑结构，也是维持内侧纵弓完整性的主要解剖结构，尤其是在胫骨后肌腱的动态支撑受损时。因此，我们试图进一步阐明该韧带复合体的解剖组成和尺寸。
对30例采用防腐技术保存的成年尸体踝关节离断足进行解剖。
上内侧韧带（SML）在上内侧和下外侧边界处的平均长度分别为42.51±3.93mm和33.44±3.34mm。在载距突和舟骨粗隆水平的宽度分别平均为20.00±2.35mm和10.26±2.05mm。足底内侧斜（MPO）韧带在内侧和外侧边界处的平均长度分别为23.56±2.15mm和21.20±1.42mm。在舟骨侧和跟骨侧的宽度分别为2.71±0.39mm和8.14±0.56mm。足底下纵（IPL）韧带在内侧和外侧边界处的长度分别为4.26±0.43mm和2.66±0.42mm。在跟骨和舟骨附着处的宽度分别为5.21±0.53mm和3.39±0.39mm。
弹簧韧带复合体的SML和MPO成分难以区分。本研究试图阐明SLC这些成分的尺寸和形态。
这一研究成果可能有助于希望更精确修复该韧带的外科医生。
