Type Ii Accessory Navicular Treatment

Overview
In an ideal situation, the navicular bone and the accessory bone will fuse together to form one bone. The problem that occurs is that sometimes the two bones do not fuse together and the patient is left with what is known as a fibrous union or basically a non solid union of bone to bone. This fibrous union is more like scar tissue and in theory can cause pain when excessive strain is placed upon it.



Causes
People who have an accessory navicular often are unaware of the condition if it causes no problems. However, some people with this extra bone develop a painful condition known as accessory navicular syndrome when the bone and/or posterior tibial tendon are aggravated. This can result from any of the following. Trauma, as in a foot or ankle sprain. Chronic irritation from shoes or other footwear rubbing against the extra bone. Excessive activity or overuse.

Symptoms
Symptoms of accessory navicular include. Bone lump on the inside of the foot. Redness and swelling. Pain.

Diagnosis
To diagnose accessory navicular syndrome, medical staff ask about the patient?s activities and symptoms. They will examine the foot for irritation or swelling. Medical staff evaluate the bone structure, muscle, joint motion, and the patient?s gait. X-rays can usually confirm the diagnosis. MRI or other imaging tests may be used to determine any irritation or damage to soft-tissue structures such as tendons or ligaments. Because navicular accessory bone irritation can lead to bunions, heel spurs and plantar fasciitis, it?s important to seek treatment.

Non Surgical Treatment
For less severe symptoms, decreasing or modifying activity, such as avoiding aggravating activities, may suffice. Ice and NSAIDS can be used to help control pain. An arch support or an orthotics may help to stabilize the arch during this time. When rubbing on the bump causes pain, a doughnut pad can be worn. Exercises to increase range of motion and improve movement should still be used.



Surgical Treatment
rolotherapy Strengthens the ligaments, tendons and muscle attachments affected by ANS. Prolotherapy is an injection technique that works to strengthen these ligament, tendon, and muscle attachments by causing a mild anti-inflammatory response in the tissues. Prolotherapy supports the body’s normal healing response to injury. The solution directed at the injured and weakened tissue will cause an influx of blood supply and regenerative cells to come to the area. As part of this healing cascade, collagen cells will also be deposited at the injured site. The tissue, which is made mostly of collagen, will become stronger and tighter as these new collagen cells mature. The injured tissue becomes healthy again. When the weakness or injury in these structures is resolved, often times the symptoms with ANS are resolved and the patient no longer suffers from chronic foot pain. In our experience, patients typically feel better soon after treatment. However, if the person desires to run again or continue to be very active, it may take 3-5 treatments to fully resolve the condition. Activity is increased during treatment as symptoms resolve.
