Foot/Ankle

In the Ankle/Foot, there are 26 bones, 107 ligaments, 19 muscles, and 4 arches.  

Arches
1.  Medial Longitudinal Arch:  This acts as a shock absorber.  It is the most prominent and has the most strain during the gait cycle.  Look at the heels of your shoes.  If you are wearing out the outside of your heels faster than the inside, this arch is way too tight.  When this arch is tight, it acts like a bow and goes upward.  This then dumps all your weight on the outside arch, and wears out your outside heel faster.  

If this arch collapses (flat foot), this will result in the Tibialis Posterior (a calf muscle) receiving more stress, if there is a subluxation in one of the lower legs.  The Tibialis Posterior supports this arch, along with the Flexor Hallicus Longus.  

2.  Lateral Longitudinal Arch:  This keeps the foot rigid during the heel strike to mid stance.  Look at the heels of your shoes.  If you are wearing out the inside of your heels faster than the outside, this arch is way too tight.  When this arch is tight, it also acts as a bow and goes upward.  This then dumps all your weight on the inside arch, and wears out your inside heel faster.  

3.  Transverse Arch:  This arch is between all 3 Cuneiforms, Cuboid, and the Metatarsal bases (part of the long foot bones near the ankle bones).  This provides shock absorption and stability.  

4.  Metatarsal Arch:  It is between the Metatarsal heads ( the part of the long foot bones near the toes).  This does the same function as the transverse arch

Now we will explain the subluxation (misalignment) patterns.  There are many Chiropractic Techniques to align these bones back to their normal position.  Of course our clinic has some techniques as well.  We can adjust these bones manually or with an activator (instrument).  Some people are hesitant about manual adjusting of the foot or ankle, and prefer the instrument.  Other people just prefer the manual adjusting.  It is a preference.  Either way, your foot and ankle will be adjusted.  

Talus Bone
The keystone to the ankle.  It is the most important ankle bone to adjust.  The big leg bone (Tibia) sits on top of this.  It subluxates in a complicated combination.  The combination is anteriorly, medially, and superiorly.  

Calcaneous Bone

This bone also has a complicated subluxation pattern.  The pattern is posteriorly, superiorly, and medially.  When this bone subluxates, it sets up a domino effect across the entire foot.  I have also seen it subluxate posteriorly, superiorly, and laterally

Navicular Bone

This likes to subluxate anteriorly and medially.  This bone forms a joint to your Talus bone (the Tranverse Tarsal Joint).  If you have a kicking type of injury, I would definetely check to see if this bone is in alignment

Cuboid Bone

This ankle bone is just proximal to the 5th foot bone (part of last long foot bone nearest to ankle).  This bone likes to subluxate anteriorly and laterally.  

We would recommend you especially check to see if this bone is misaligned if there is a dull ache in the calf muscle.  

The cuboid is the keystone of the lateral longitudinal arch.  The Fibularis tendon supports the cuboid.  

If the sacrum bone is not holding the adjustment, the cuboid is one of the bones to check if it is in the right alignment (we would also check the Calcaneous, 4th and 5th Metatarsal, and head of the Fibula)

Cuneiform bones

You have 3 of them.  They are all next to each other in the middle of the ankle.  They like to subluxate posteriorly

They create stability for the Transverse Arch.  

We would especially check these bones if there is pain on the bottom of the mid foot.  We include this bone in our routine check (as we include all foot/ankle bones)

Metatarsal Bones (Long Foot Bones)

There are 5 of them.  The base (part of the bone closest to the ankle) likes to subluxate anteriorly.  The head (part of the bone near the toes) likes to subluxate posteriorly.  We call this a dropped Metatarsal head.  

We would advise you call the office if this area has tenderness.  

Toes

Yes, we adjust the toes for you.  We are called Head to Toe Chiropractic.  (and yes, the head can also be adjusted, along with the neck)

Plantar Fascia

This is a fancy name for the soft tissue on the bottom of your foot.  What you walk on all day long.  There is a tug of war going on here, with the heel as the rope knot in the middle.  Your calf muscles on one end of the rope, and your plantar fascia on the other end of the rope.  Your heel is in the middle.   Your heel is the rope knot in this case.  

If you have Plantar Fascia, then this means the soft tissue needs to be relaxed, before a Heel Spur happens.  Because if left untreated, we will bet you a Heel Spur is on the way. 

To work on this problem....In addition to adjusting the foot/ankle (and checking to see if the knees, thighs, hips, sacrum, and low back need adjusting), we will do a lot of soft tissue, muscle work on the plantar fascia and all 3 of your calf muscles.  Did you know that one of your calf muscles almost inserts on just about everything on the bottom of the foot (theTibialis Posterior..must be worked on).  

We will also check some other muscles on the bottom of the foot:

Abductor Hallucis
Abductor Digiti Minimi
Flexor Digitorum Brevis
Quadratus Plantae
Lumbricals
Flexor Hallucis
Flexor Digiti Minimi
Adductor Hallucis

Heel Spur

If you left the Plantar Fascia untreated, or got treated (and that was unproductive), now you have a Heel Spur.  The reason being is because the tug of war example above.  Now both Plantar Fascia and the Calf muscles are tight.  They will now pull the soft tissue off the top layer of the heel bone, leaving a small hole.  Your body does not like that, so it fills in that small hole with bone.  The patch job that is does isn't the best though, and some bone protrudes off the heel.  This is a Heel Spur

To work on this problem, we will go through the same exact process as we did for Plantar Fascia.
