The National Council on Aging is launched a Falls Prevention Awareness Day on Sept. 23, 2015. This year’s theme is “Take a Stand to Prevent Falls.” Hundreds of state and national associations are building awareness that falls are the leading cause of fatal and nonfatal injuries for people 65 years of age and older; however, falls are not an inevitable part of aging. Seniors have the power to reduce their risk of injury by taking preventive measure to maximize their independence and quality of life.
Podiatrists play a key role in the prevention of falls for seniors because they are trained to identify patients who are at risk for falls, and able to address the primary biomechanical problems that cause falls. Problems that contribute to falls include osteoarthritis, unstable foot and ankle joints and pain, weak muscles, Dropfoot (Hemiplegia), posterior tibial tendonitis, tendon contraction, peripheral neuropathy, flatfeet, malformations in the toes, Equinus Foot, Charcot Foot, gait abnormality, and lack of muscle coordination (Ataxia).
The foot and ankle problems that place seniors at highest risk of falling have Chronic Ankle instability, Hallux Rigidus (big toe arthritis), and Ankle, Hindfoot, and Midfoot arthritis.
Here is a brief overview of the symptoms, causes, diagnoses, and treatments for these conditions.
Chronic Ankle Instability
Chronic Ankle Instability is characterized by a weak ankle that “gives way” on the lateral (outer) side of the ankle on a fairly regular basis. This occurrence is unpredictable and can occur while walking, running, or when standing. Common symptoms include pain, tenderness, and swelling.
The primary cause is usually the result of a prior ankle sprain or injury (i.e. fracture) that did not rehabilitate properly or fully heal. Consequently, ligaments surrounding the ankle remain stretched, weak, and sometimes torn. Other causes are not injury related. These include arthritis, inflammation in the synovium (joint lining), and a buildup of scar tissue, a damaged nerve, or nerve entrapment condition.
Physiotherapy is the most common treatment to rebuild ankle strength. Special bracing is also used to provide support. Surgery is considered if ligaments need to be tightened on the outside of the ankle to add support. In some cases, a tendon may be grafted from the other ankle to rebuild stability.
Hallux Rigidus (Big Toe Arthritis)
Hallux Rigidus (hallux rig·i·dus) is a form of degenerative arthritis in the metatarsophalangeal (met-a-tar-so-pha-lan-gel-al) “big toe” joint (MTP) that usually develops in adults between the ages of 30 and 60. This condition is the most common form of arthritis in the foot. It is a progressive condition that limits the toe’s range of motion over time.
This condition occurs when the cartilage of the big toe is injured or because of an abnormal foot anatomy that puts an excessive stress load on the MTP joint. The deterioration of articular cartilage covering at the end of the bone results in a bone-on-bone condition.
Initial symptoms include joint stiffness, swelling, pain, discomfort, and restricted range of motion. The condition tends to be aggravated during cold and damp weather. Walking becomes abnormal and is usually associated with a limp that results in balance impairment. Recreational and fitness activities are restricted and so is manual labor that requires stooping or squatting.
As the condition advances, pain is present even during rest. Walking is difficult and evidenced with a limp. Bone spurs in the heel often develop making it uncomfortable to wear shoes, especially high heels. Often, these conditions lead to pain in the knee, hip, and lower back.
Biomechanics and structural abnormalities are the primary causes of Hallux Rigidus. It is not caused by genetics but it can be the result of inheriting a foot type that is prone to developing this condition. People who have excessive pronation (rolling in) of the ankles or fallen arches are more prone to develop this condition.
This condition can also result from injury such as stubbing your big toe or from work activities that require excessive stooping and squatting or caused by gout or rheumatoid arthritis (inflammatory diseases).
Early diagnosis will help avoid further problems. Diagnosis is usually made after X-rays are taken to determine the extent of degeneration and bone spur formation. Blood tests and aspiration may also be used to confirm diagnosis of septic arthritis.
Non-surgical treatments include anti-inflammatories and pain medications. Shoes that provide a larger toe box and stiffer sole with a rocker panel design feature should be used. Sometimes a metal brace is placed inside the sole to limit toe bending. Cold and hot therapy is sometimes used as well as cortisone injections.
Surgery may be done if therapy fails. Depending on the severity of the condition, there are three types of surgeries that may be performed including: a Cheilectomy (kl-lek’-toe-me) for mild to moderate MTP damage, an Arthrodesis (are-throw-dee’ sis) permanent fusion of bones if the cartilage is severely damaged, or Arthroplasty (are-throw-plas’tee) ankle replacement with an artificial joint.
Ankle, Hindfoot and Midfoot Arthritis (Degenerative Joint Disease)
Arthritis is also common in three other locations of the ankle, hindfoot, and midfoot. There are three types of arthritis. Osteoarthritis, commonly referred to as wear and tear arthritis, typically occurs after reaching middle age. Rheumatoid Arthritis is a system-wide disease that attacks and destroys cartilage. Post-Traumatic Arthritis occurs following an injury such as a sprain, fracture, or torn/stretched ligament.
Arthritis symptoms of the foot vary depending on where it is present; however, the common symptoms include swelling, stiffness and reduced mobility, tenderness and pain, and difficulty walking.
Nonsurgical treatment may include the following: cold therapy; anti-inflammatories and pain medications; use of supportive footwear, custom orthotics, foot braces, balance braces, and casting; home therapy; participating in non-load bearing recreation activities; corticosteroid injections; and laser therapy.
Surgical treatment is considered when nonsurgical treatment does not provide sufficient response or pain relief. Surgery consists of Arthroscopic Debridement, Arthrodesis (fusion) and Arthroplasty (joint replacement).
Arthroscopic Surgery is typically done during the early stages of arthritis; and Arthrodesis and Arthroplasty are done at end of stage arthritis.
Arthrodesis is a complete fusion of the joint accomplished by the use of hardware to hold the bones in place while the joint fusion occurs. Bone grafts are sometimes used to replace a missing bone or if there is bone loss to fuse the bones of the joint completely.
Fusion is usually very successful and has does not present problems for healing. Additional surgery is necessary if problems occur from a lack of bracing. Arthritis may be a long-term problem if stress is applied to the fused and adjacent joints.
Candidates for Arthroplasty Surgery (joint replacement) are at end stage arthritis, ankle joint surfaces are destroyed, and patients are in severe pain and unable to do normal daily activities. Because of advances in implant design, this procedure is gaining popularity and becoming the treatment of choice.
A wide range of strategies are available to prevent falls. If you have a balance problem or arthritis in your feet or ankles, call (217) 787-2700 to schedule an appointment at the Foot & Ankle Center of Illinois in Springfield, Decatur or Carlinville.

Stress fractures are notoriously misdiagnosed and undertreated. In many cases, symptoms may persist for an extended period of time before the diagnosis of a stress fracture is even made. That’s because stress fractures don’t typically occur from an unforeseen trauma, as with a sprain, but rather from repetitive stress.
What Are Stress Fractures?
Stress fractures are tiny, hairline breaks in the bones. They can occur in any bone, but most often afflict the weight-bearing bones of the lower leg and foot. Athletes are especially susceptible to stress fractures, as this common injury is often a problem of overuse. It frequently results from overtraining and high impact sports, such as running, basketball and tennis. People with an abnormal foot structure or insufficient bone may also be more vulnerable to suffer a stress fracture.
What Are the Symptoms of Stress Fractures?
Pain is the primary symptom of a stress fracture. In the early stages, the pain may begin toward the end of an activity and resolve with rest. Untreated, the pain will eventually persistent with minimal activity.
The most common symptoms of stress fractures include:
Pain with or following normal activity
Pain at the site of the fracture
Tenderness and swelling at a point on the bone
Pain intensified with weight bearing
Rest, ice, compression, and elevation are recommended as an initial treatment plan for stress fractures. You should also minimize all weight bearing activities until you have fully recovered. Other treatments may include immobilization of the foot, footwear modifications, orthotic devices and in some severe cases, surgery. Rest is the key to a full recovery, and returning too quickly to normal activity may result in more serious damage.
Overuse injuries and stress fractures aren’t completely unavoidable, but you can take extra care to help prevent stress fractures from occurring. Remember to increase any activity or training program slowly and gradually. Wear supportive footwear with good cushioning to help manage the forces placed on your feet and legs during high impact activities. If pain or swelling returns, stop the activity and rest for a few days.
Stress fractures come on gradually and may not present obvious symptoms at first, so it’s important to recognize the early warning signs to prevent further damage. If you suspect a stress fracture, contact our office right away for an evaluation. Proper diagnosis is essential to prevent further damage and improve recovery time, as stress fractures tend to get worse and may even lead to a complete break if not treated right away. A podiatrist will examine your foot or ankle, take an x-ray to determine if there is a break or crack in the bone, and recommend an appropriate treatment plan for optimal recovery.
