Extensor apparatus of the lesser toes: anatomy with clinical implications--topical review.

Unlabelled: Lesser toe deformities are one of the most common conditions faced by orthopedic surgeons. Knowledge of the anatomy of the lesser toes is important for ensuring correct diagnosis and treatment of deformities, which are caused by factors such as muscle imbalance between the extensor apparatus and flexor tendons. However, this apparatus has not received sufficient attention in the literature. In addition, the large number of inaccurate and erroneous descriptions means that gaining an understanding of these structures is problematic. The objective of the present article is to clarify the anatomy of the extensor apparatus by means of a pictorial essay, in which the structures involved will be grouped and discussed in detail. The most relevant clinical implications will be addressed.
