Introduction[edit | edit source]

Pes equinus/ Club foot is a condition in which the upward bending motion of the ankle joint (dorsiflexion) is limited.[1] It's also known as tight calf and is typically associated condition of a primary diagnosis of a bunion( Hallux valgus) and most commonly seen in flat foot or pes cavus.[2]In this deformity, an alteration in gait may occur; a patient may also have difficulty climbing stairs, dressing and in lifting the foot up so a patient may need to lift the leg on the affected side up higher, to “step over” the foot.[3]

Classification[edit | edit source]

Equinus can be classified in multiple ways according to etiology, apex of equinus, spastic and non-spastic forms in addition to soft tissue causes of joint restriction.[4]

Etiology/Causes[edit | edit source]

Equinus is frequently caused by tightness in the calf muscles (the soleus and/or gastrocnemius muscles) or the Achilles tendon. Some people may have this feature congenitally (existing at birth) or inherited it. Others develop this tightness as a result of wearing high-heeled shoes frequently, being in a cast or using crutches. Other contributing factors include diabetes or having a shorter leg than other. The patient may develop equinus if a bone or bone fragment restricts movement of the ankle (for instance, after an ankle injury). Rarely, calf muscular spasms can induce equinus and may be a symptom of an underlying neurologic condition.Equinus.[5]

Foot Problems Related to Equinus[edit | edit source]
