The inferior extensor retinaculum (IER) is an aponeurotic structure, which is in continuation with the anterior part of the sural fascia. The IER has often been used to augment the reconstruction of the lateral ankle ligaments, for instance in the Broström-Gould procedure, with good outcomes reported. However, its anatomy has not been described in detail and only a few studies are available on this structure. The presence of a non-constant oblique supero-lateral band appears to be important. This structure defines whether the augmentation of the lateral ankle ligaments reconstruction is performed using true IER or only the anterior part of the sural fascia. It is concluded that the use of this structure will have an impact on the resulting ankle stability.
下伸肌支持带（IER）是一种腱膜结构，与腓肠筋膜前部相延续。IER常被用于增强外侧踝关节韧带的重建，例如在布罗斯特伦-古尔德手术中，据报道效果良好。然而，其解剖结构尚未得到详细描述，关于该结构的研究也仅有少数。一条位置不恒定的斜行上外侧带的存在似乎很重要。该结构决定了外侧踝关节韧带重建增强是使用真正的IER还是仅使用腓肠筋膜前部。得出的结论是，该结构的使用将对最终的踝关节稳定性产生影响。
