In the the first blog of this series we looked at anatomy and function of the foot and then proceeded to discuss some common injuries in part two. This part looks into exercises that can help keep your feet supple and strong for everyday life.

In the last blog we introduced the anatomy and function of the foot (Part one anatomy and function). With this knowledge it can be seen that the foot is quite a complex structure and with so many components you would think quite a lot can go wrong. If you think how often you walk, run or jump and the forces going through your feet it is quite immense, and yet our feet seem to tolerate this on a daily basis. However there are occasions where trauma occurs or our feet just can’t recover as they should. Below are some common injuries your feet might experience.
Plantar fasciitis is one of the most common forms of foot pain. It is common in runners and older adults. It is often associated with biomechanical issues due to excessive pronation or supination. It is an overuse injury and what we would term a tendinopathy. You may have experienced tennis elbow or Achilles tendinopathy. Which is a similar condition just affecting a different part of your body. Tendinopathy in short is when the tendon is not healing in the normal manner, it can fray, become thickened and be painful.
Flat feet or high arches can increase the risk of plantar fasciitis. Tightness in the calf muscle, hamstrings and gluteals can also increase the risk. Plantar fasciitis has a gradual onset of pain which is often located on the medial aspect of the heel and experienced after activity. However when it becomes more severe pain can be experienced when weight bearing and on activity. Periods of inactivity during the day can also increase the pain when commencing activity again. Stretching the foot and fascia also can cause pain.
The common bones in the foot that can suffer stress fractures are the calcanous, navicular and metatarsals. Calcaneal stress fractures are common in runners, military personnel, ballet dancers and sports that involve jumping. Having poor heel cushioning, overstriding and a heavy load can all increase the risk. The onset of pain is insidious in nature and aggravated by weight bearing. There is localised tenderness to the medial or lateral border of the heel.
Navicular stress fractures are the most common stress fracture in the foot. It can occur in sprinters, jumping sports and hurdling. It is an overuse injury and is thought to be due to training errors and impingement of the bone between other tarsal bones. Decreased dorsiflexion in the ankle is thought to perhaps bring about an increase in compensatory dorsiflexion in the foot increasing the stress placed on the navicular. Individuals often experience a midfoot localised ache, radiating along the medial aspect of the medial longitudinal arch. It often gets better with rest.
Metatarsal stress fractures occur with excessive loading of the forefoot and muscle fatigue. Forefoot pain is experienced and aggravated by activity. Pain gradually worsens with activity and tenderness over the metatarsal is present. Stress fractures don’t always present themselves on x-ray straight away so can be harder to diagnose than a complete fracture. However if one is suspected then management strategies can be implemented until diagnosis is confirmed
Metatarsalgia is an inflammatory condition of the metatarsal phalangeal joints. It is caused by excessive pressure over prolonged periods of time. It is associated with high arches, excessive pronation of the foot, clawing/hammer toe, tight extensor tendons of the toes, prominent metatarsal heads and Morton’s foot. Pain is aggravated by forefoot weight bearing and affects the mid stance and propulsive phase of walking. Pain is gradual in onset and local tenderness over joints is present. Passive flexion of the toe causes pain and a v shape between toes can also be an early sign.
This is when the big toe deviates laterally, it is more common in women and older people. There are a number of factors that can lead to the development of a bunion constricting footwear like high heels, excessive pronation of the foot, long first metatarsal (big toe), trauma to the medial and plantar ligaments and trauma to the medial sesamoid bone. As the deformity develops so does the pain over the medial border of the big toe this can be relieved by removing footwear or wearing wider shoes.
Toe clawing is not necessarily a painful condition but suggests that the long flexor tendons are tight. During the propulsion phase of gait the long flexors contract to stabilise the toes, if the foot is unstable the long flexor tendons excessively contract causing the toes to claw at the ground to maintain stability. If this continues then it could affect other areas of the foot or body as they compensate.
The above are just a few examples of injuries that can develop with feet. There are many others. The majority of the above injuries can be avoided by performing exercises and taking other everyday precautions. Part three of this series will address these solutions to help you maintain happy feet.

Feet are an important part of our lives. They continuously absorb a lot of force to allow us to move and balance in a number of ways. When feet are doing their job life is great but if there is something wrong then daily life can be affected hugely. Do you take care of your feet, understand how they work or want to know more about these incredible structures then continue reading?
Today we are going to discuss the anatomy and function of the foot. Part two will look into problems that may arise with feet and how they can affect the rest of the body. In part three and to conclude the series then ways to keep your feet healthy for pain free movement will be discussed.
The foot is quite a complex structure compared to the rest of a human body. It is made up of 26 bones, 30 joints and over a 100 muscles, tendons and ligaments all working together to create an apparatus that allows movement, and stability while bearing the weight of the whole body.
The foot is separated into three regions the hindfoot, midfoot and forefoot. The hindfoot is made up of the talus and calcanus. The talus articulates with the fibula and tibia to form the ankle joint (talocrural joint) and the calcanous is your heel. The midfoot has five tarsal bones, which are wedge shaped and help form the arch of your foot. The forefoot contains the metatarsals and phalanges which form your toes.
As noted earlier the foot bears the weight of our bodies. When walking the pressure on the feet increases twofold and then fourfold when running. This is a huge amount of pressure in such a small structure. As a result the foot needs to be able to absorb and distribute weight. It also needs to be able to help with propelling the body forward in our chosen gait. The foot has three arches the medial longitudinal, lateral longitudinal and transverse arch. These arches allow weight to be distributed throughout the foot as well as allowing the foot to make adjustments to uneven terrain. The medial longitudinal arch is the primary load bearing and shock absorbing structure of the foot. It forms the instep of the foot.
The plantar fascia makes up the primary passive component (along with the bony structures) of the medial longitudinal arch. It covers the sole and side of the foot. Active toe extension stretches the fascia which adds tension to the medial longitudinal arch. It helps stabilise the foot especially in the push of phase of movement. Other structures such as muscles help stop the arch from lowering to much when weight bearing and likely protects against stress related injuries.
The foots ability to repeatedly transform from a flexible and shock absorbing structure to a rigid lever type structure is really important in our ability to move and weight bear. If there is a problem in the foots structure then our ability to weigh bear and move is compromised and our everyday living is profoundly affected. In the next post injuries that can arise with feet will be discussed.
