The Sinus Tarsi Stent (Implant) is a Permanent Correction
Advanced Foot Clinic specializes in helping patients with flat feet and fallen arches. It is very common that most patients come in when they are children for this can be painful and a big inconvenience. This page explains the various conditions of the foot and can help you better understand and answer some questions you may have. We hope you find this page informative and helpful.
The Sinsus Tarsi Implant procedure is performed with a small stent which is placed into a space below the ankle bone whereby preventing the abnormal excessive motion and restoring normal motion. This is a minimally invasive procedure which can be performed from three years old and up. There is restoration of the normal motion between the talus and calcaneus.The correction is achieved internally, so no matter what style of shoe is being worn correction is being achieved. Additionally, regardless of whether or not a shoe is being worn, correction is being achieved.
A sinus tarsi stent cannot get lost or accidentally thrown out. Once placed it should remain in-situ for the rest of the patient’s life. It does not need to be replaced yearly. The metallic stents do not wear out. If for some reason the patient did not tolerate the correction or if the stent had some how become displaced it is possible for the stent to be removed without further damage to the space. These stents are not placed into a joint but a bone space. The sinus tarsi (sinus or canalis) does not contain any cartilage and therefore cannot develop arthritis. If the stent did not achieve the desired correction other additional surgical procedures could be performed in conjunction with subtalar arthroereisis. Additionally, worse case scenario the stent could be removed without any damage to the sinus tarsi and the more aggressive rearfoot surgical procedures could still be performed. A subtalar arthroereisis procedure is completely reversible.
Dr. Arabshahi has been designated as a Master Surgeon in the Salem/Portland area who does Sinus tarsi Implant.
What Is Hyperpronation?
Hyperpronation is a common deformity in many patients' feet and occurs when there is too much pronation (normal motion of the foot) happening within the foot or feet. The strenuous motion of the ankle bone and possibly in the rest of the foot occurs with every step taken; resulting in the unnatural closure of the sinus tarsi.
Can Walking With Hyperpronation Be Dangerous?
The second most common conscious function of our body is walking. Walking is the best form of exercise from what we are told. However, there can be many dangers of walking with hyperpronation that can lead to more than just problems with our feet. The feet are the foundation to our body and even if there is just a slight excessive pronation, this can lead to other deformities within our body.
What Are Growing Pains?
This is actually an inflammation of the lining of the leg bones. In a hyperpronating foot, the leg muscles must work. This over-activity leads to greater pull of the muscle on the leg bones. After a day of play and once the child gets into bed for the night and is no longer walking/standing, the inflammation will set-in and pain ensues. No bone in our body will hurt when it grows.
Do I Have A Flattened Arch?
This is a very common finding. If the child is sitting with their foot off the floor they have a nice arch, but when they stand the arch flattens. However, hyperpronation can also be present with a high arched foot.
What Is Out-Toed Walking?
Normally the feet should point straight in front of the legs when walking and if viewed from behind only the fifth toes of the foot should be seen. In a hyperpronated foot usually greater than the fifth toes can be seen. This is referred to "too many toes sign".
What Does Tip-Toe Walking Do To My Feet?
This decreases the muscle activity and is more efficient in a hyperpronated foot.
What Structural Deformities Does Hyperpronation Cause?
Many times children have bunions, hammertoes, etc. at a very young age due to the hyperpronation.
Why Do My Shoe Laces Keep Coming Untied?
With Hyperpronation excessive motion of the foot causes repetitive pressure to the sides of the shoes, which pull on the laces. Eventually the shoe laces become untied. In a lot of cases the child will not want to tie the shoes in the first place or will get shoes without laces.
My Child Is Always Wanting To Be Held Or Sits Down Frequently When Walking:
Walking or standing is exhaustive due to the excessive muscle activity. After prolonged walking at the grocery store, shopping mall, or theme park the child with a hyperpronating foot will want to take very frequent breaks or if young enough will want to be held.
My Child Has Poor Posture:
When the talus deviates, it alters the skeletal system affecting the knees, hips and back. When standing the back muscles try to compensate for this but only for short periods of time. Usually a child's shoulders will slump or they cannot stand on both feet for more than a few moments. Parents always try to reprimand the child but it is futile.
My Child Has Knee, Hip, Back, Neck Symptoms:
Any or all of these can be present in a child with a hyperpronated foot. Children should not suffer with these conditions at such a young age unless a deformity is causing this. Normally, these symptoms are associated after weight-bearing activities.
There Is A Solution...
The Parent Sinus Tarsi Implant is self-seating/positioning feeling comfortable and natural and is a great solution. This self-seating/positioning makes it a great fit, whereas other implants are not. The sinus tarsi is made up of the deeper canalis portion and the outer sinus portion. The procedure itself generally takes less than 15 minutes and is performed under twilight sedation. Below are some examples of existing patients that have benefited from this procedure and have had great results.
