A high arch foot is known in medical terms as a ?subtle cavus foot?. People with high arch feet tend to be very stiff through the midfoot, with very little movement through the main midfoot joints (ex. the talo-navicular joint). The heel tends to be pointed inward in what is known as a varus position (Figure 1a). This foot position can be easily identified on examination by looking at the feet head on with the patient standing. If the inside edge of the heel is visible from the front (this is known as a peek-a-boo heel), then the individual likely has an inwardly pointed heel (varus heel).
Cavus foot commonly occurs as a result of an underlying medical or neurological condition, such as polio, muscular dystrophy or cerebral palsy. Cavus foot may also occur as a result of congenital defects. They may be inherited from a parent, or they may result from an orthopedic condition or a disease of the nerves or muscles.
Cavus foot is typically identified by a high arch that is noticeable when standing. Additional symptoms may include hammertoes, claw toes, foot instability, pain when walking or standing or calluses on the heel, ball or side of the foot. In some cases, individuals with cavus foot may also suffer from foot drop, which causes those affected to drag their feet when walking. As compared to a normally arched foot, high arches cause more pressure to be put on the metatarsals (the bones of the forefoot). Over time, this can result in pain, weakness and fatigue in the feet. High arches also shorten the feet, potentially making it difficult for a person to find shoes that fit. People with high arches may need special orthopedic shoes or inserts for support.
If a neurological condition is suspected to be at the heart of your problem, your podiatrist will probably examine your leg as well as your foot, and may also refer you to a neurologist, who is specially trained in recognizing such conditions.
Non Surgical Treatment
Treatment of high arches really depends a great deal on what?s causing them. If it?s not likely the condition will worsen with time, usually the case when the cause is NOT neurological, then more conservative treatments may be effective, enabling you to live without significant pain.
Ideally, surgeons should first repair the source of the traumatic event such as the ankle instability or peroneal tear in order to stabilize the laxity about the ankle and subsequently judge the level of deformity in the foot pain cream (kashaAzzaro.jimdo.com). For example, a varus talus position caused by ankle instability will often make the cavus foot position look worse prior to repair of the lateral collaterals than after repair of the collaterals. After repositioning and stabilizing the talus, one can better judge the varus of the heel and first metatarsal position.
