Common Causes of Foot Drop

Foot drop is a condition in which the foot drags or has difficulty lifting while walking, often caused by weakness in the muscles that raise the front of the foot and toes. This weakness can develop from problems in the muscles themselves, nerve damage that interrupts signals to the foot and ankle, or structural issues that affect movement. People with foot drop often change their walking style to avoid tripping, sometimes lifting the knee higher than normal to clear the toes from the ground. Over time, this can create additional strain on the joints of the foot and ankle. Causes include direct injury to the dorsiflexor muscles, nerve compression, diabetic neuropathy, or stroke-related changes. A podiatrist can identify the underlying reason for the problem and recommend supportive devices to improve mobility. If you have problems lifting your feet while walking, it is suggested that you make an appointment with a podiatrist for an exam, diagnosis, and treatment.

Biomechanics in Podiatry
Podiatric biomechanics is a particular sector of specialty podiatry with licensed practitioners who are trained to diagnose and treat conditions affecting the foot, ankle and lower leg. Biomechanics deals with the forces that act against the body, causing an interference with the biological structures. It focuses on the movement of the ankle, the foot and the forces that interact with them.
A History of Biomechanics
- Biomechanics dates back to the BC era in Egypt where evidence of professional foot care has been recorded.
- In 1974, biomechanics gained a higher profile from the studies of Merton Root, who claimed that by changing or controlling the forces between the ankle and the foot, corrections or conditions could be implemented to gain strength and coordination in the area.
Modern technological improvements are based on past theories and therapeutic processes that provide a better understanding of podiatric concepts for biomechanics. Computers can provide accurate information about the forces and patterns of the feet and lower legs.
Understanding biomechanics of the feet can help improve and eliminate pain, stopping further stress to the foot.

Biomechanics in Podiatry
Podiatry is a branch of medicine that deals with the study, diagnosis, and treatment of foot and ankle conditions. There are various subdivisions in podiatry; biomechanics is one of them. Biomechanics is the way in which the bones, muscles, and joints of the feet and lower limb interact with each other.
Our feet play crucial roles in the way we move, and it is rare to have feet that are completely symmetrical. Common biomechanical issues include high or low arches or uneven leg heights. Excessive pronation often leads to fallen arches, or flat feet, and is a common cause of running injuries. People whose feet are over-pronated tend to have flexible and unstable feet. Pain is usually experienced during walking and running.
At times, people may be able to adapt to these abnormalities without any difficulties, but in other cases, these issues can cause a great deal of pain. This pain occurs because the joints, muscles, ligaments, and tendons are put under an excess amount of stress during movement. Common symptoms of biomechanical problems stemming from the feet include hip pain, knee pain, leg cramps, ankle pain, lower back pain, weak ankles, tripping, heel pain, Achilles pain, and shin splints.
Many biomechanical issues can be treated with orthotics. Orthotics are shoe insoles that are used to help control the way the foot operates. They can provide relief from foot pain, heel pain, and knee pain. Depending on your specific case, you may need to purchase over-the-counter orthotics or custom orthotics to fit your feet. Your podiatrist will be able to prescribe the perfect orthotic for your feet to help you walk around with ease.
Gait is defined as the way we move our bodies from one point to another. This is usually done by either walking or running. Gait analysis is a method used to assess the way we walk or run to highlight biomechanical abnormalities. Gait analyses are a great way to take a detailed look at how you walk and how your foot moves while you walk. An examination of the feet will help your podiatrist understand why you are suffering pain in other parts of your body.
Protecting Surgical Healing After Ankle and Tibia Fractures

After ankle or distal tibia surgery, preventing wound complications is essential for proper recovery. Incisional Negative Pressure Wound Therapy, or NPWT, has been shown to significantly lower the risk of infection and promote faster healing. This method gently applies controlled suction to the closed surgical incision, helping remove excess fluid and improve blood circulation around the wound. Better circulation delivers oxygen and nutrients to the tissue, supporting the body’s natural repair process and reducing swelling. Studies show patients treated with NPWT experience fewer complications and faster recovery times compared to traditional dressings. This advanced therapy is particularly helpful for individuals with higher risk factors such as diabetes or poor circulation. If you are recovering from foot or ankle surgery, it is suggested that you consult a podiatrist as to whether incisional NPWT can help protect your incision and promote optimal healing.
Wound care is an important part in dealing with diabetes. If you have diabetes and a foot wound or would like more information about wound care for diabetics, consult with Ambrose Su, DPM from Cascade Foot Clinic. Our doctor will assess your condition and provide you with quality foot and ankle treatment.
What Is Wound Care?
Wound care is the practice of taking proper care of a wound. This can range from the smallest to the largest of wounds. While everyone can benefit from proper wound care, it is much more important for diabetics. Diabetics often suffer from poor blood circulation which causes wounds to heal much slower than they would in a non-diabetic.
What Is the Importance of Wound Care?
While it may not seem apparent with small ulcers on the foot, for diabetics, any size ulcer can become infected. Diabetics often also suffer from neuropathy, or nerve loss. This means they might not even feel when they have an ulcer on their foot. If the wound becomes severely infected, amputation may be necessary. Therefore, it is of the upmost importance to properly care for any and all foot wounds.
How to Care for Wounds
The best way to care for foot wounds is to prevent them. For diabetics, this means daily inspections of the feet for any signs of abnormalities or ulcers. It is also recommended to see a podiatrist several times a year for a foot inspection. If you do have an ulcer, run the wound under water to clear dirt from the wound; then apply antibiotic ointment to the wound and cover with a bandage. Bandages should be changed daily and keeping pressure off the wound is smart. It is advised to see a podiatrist, who can keep an eye on it.

Wound Care
Diabetics must be wary of all wounds, regardless of depth or size. Diabetes, a chronic disease in which the body cannot properly use glucose the way it normally would, causes various complications that make wounds difficult to heal. Nerve damage or neuropathy will cause diabetics to have trouble feeling the pain of a blister or cut until the condition has significantly worsened or become infected. A diabetic’s weakened immune system can make even the most minor of wounds easily susceptible to infection. Diabetics are also more prone to developing narrow, clogged arteries, and are therefore more likely to develop wounds.
Wounds should be taken care of immediately after discovery, as even the smallest of wounds can become infected if enough bacteria build up within the wound. To remove dirt, wounds should be first rinsed under running water only. Soap, hydrogen peroxide, or iodine can irritate the injury and should be avoided. To prevent infection, apply antibiotic ointment to the wound and cover it with a bandage. The bandage should be changed daily. The skin around the wound may be cleaned with soap.
To prevent further exacerbation, see a doctor—especially if you have diabetes. Minor skin conditions can become larger problems if not properly inspected. As the wound heals, make sure to avoid applying pressure to the affected area.

Understanding Bunions and How to Treat Them

A bunion is a bony bump that forms at the base of the big toe when the joint becomes misaligned. It often appears as a swollen, red, and painful lump that can make walking difficult. Bunions develop due to genetics, wearing tight shoes, or foot structure issues. Risk factors include a family history of bunions, arthritis, and wearing ill-fitting footwear. A podiatrist can evaluate the severity of the bunion, provide pain relief options, recommend proper footwear, and discuss surgical correction, if needed. If you have signs of a bunion developing, it is suggested that you consult a podiatrist who can guide you on relief and management tips.
If you are suffering from bunion pain, contact Ambrose Su, DPM of Cascade Foot Clinic. Our doctor can provide the care you need to keep you pain-free and on your feet.
What Is a Bunion?
Bunions are painful bony bumps that usually develop on the inside of the foot at the joint of the big toe. As the deformity increases over time, it may become painful to walk and wear shoes. Women are more likely to exacerbate existing bunions since they often wear tight, narrow shoes that shift their toes together. Bunion pain can be relieved by wearing wider shoes with enough room for the toes.
Causes
- Genetics – some people inherit feet that are more prone to bunion development
- Inflammatory Conditions - rheumatoid arthritis and polio may cause bunion development
Symptoms
- Redness and inflammation
- Pain and tenderness
- Callus or corns on the bump
- Restricted motion in the big toe
In order to diagnose your bunion, your podiatrist may ask about your medical history, symptoms, and general health. Your doctor might also order an x-ray to take a closer look at your feet. Nonsurgical treatment options include orthotics, padding, icing, changes in footwear, and medication. If nonsurgical treatments don’t alleviate your bunion pain, surgery may be necessary.
If you have any questions, please feel free to contact our office located in Bend, OR . We offer the newest diagnostic and treatment technologies for all your foot care needs.
What Are Bunions?
Bunions are large bony bumps at the base of the big toe. Medically known as hallux valgus, a bunion is a misalignment of the metatarsophalangeal joint, or big toe joint. The misalignment will generally worsen with time if left untreated.
The exact cause of bunions is unknown, with genetics seen as a potential cause. High heels and poorly-fitted footwear, rheumatoid arthritis, and heredity all seem to be potential factors behind the exacerbation of bunions. Women have been found to be more likely to develop bunions in comparison to men.
Bunions do not always produce symptoms. The best way to tell is if the big toe is pushing up against the next toe and there is a large protrusion at the base of the big toe. You may or may not feel pain. Redness, swelling, and restricted movement of the big toe may be present as well.
Podiatrists use a variety of methods to diagnose bunions. If there are symptoms present, podiatrists will first consider that it is a bunion. If not, a physical examination will be conducted to check function of the big toe. Finally, an X-ray may be taken to view the extent of the bunion and confirm it is a bunion.
Typically, nonsurgical methods are used to treat bunions, unless the bunion has become too misaligned. Orthotics, icing and resting the foot, roomier and better fitted shoes, taping the foot, and pain medication are usually utilized first. If the bunion doesn’t go away or causes extreme pain, surgery may be required. Surgeons will either remove part of the swollen tissue or bone to straighten the toe out.
If you have a bunion, it is recommended to see a podiatrist. The longer it is left untreated, the worse it may get. Podiatrists can properly diagnose and treat a bunion before it gets worse.
Walking can be Difficult With a Heel Spur
A heel spur is defined as a bony growth surrounding the ligaments of the foot near the heel bone. It may develop as a result of existing medical conditions that can include poor circulation and various forms of arthritis. Some of the symptoms that are associated with heel spurs can include continuous foot pain, and it may be difficult to walk. It may become worse after arising in the morning, or if excessive strain has been placed on the heel in previous days. Mild relief may be found when the affected foot is elevated, and it may help to place a protective pad in the heel of the shoe. If you are experiencing heel pain, it is strongly suggested that you seek the counsel of a podiatrist who can properly diagnose heel spurs, and offer you correct treatment techniques.
Heel spurs can be incredibly painful and sometimes may make you unable to participate in physical activities. To get medical care for your heel spurs, contact Ambrose Su, DPM from Cascade Foot Clinic. Our doctor will do everything possible to treat your condition.
Heels Spurs
Heel spurs are formed by calcium deposits on the back of the foot where the heel is. This can also be caused by small fragments of bone breaking off one section of the foot, attaching onto the back of the foot. Heel spurs can also be bone growth on the back of the foot and may grow in the direction of the arch of the foot.
Older individuals usually suffer from heel spurs and pain sometimes intensifies with age. One of the main condition's spurs are related to is plantar fasciitis.
Pain
The pain associated with spurs is often because of weight placed on the feet. When someone is walking, their entire weight is concentrated on the feet. Bone spurs then have the tendency to affect other bones and tissues around the foot. As the pain continues, the feet will become tender and sensitive over time.
Treatments
There are many ways to treat heel spurs. If one is suffering from heel spurs in conjunction with pain, there are several methods for healing. Medication, surgery, and herbal care are some options.

How to Treat Heel Spurs
Heel spurs are calcium deposits that cause bone protrusions on the heel bone. Heel spurs are usually associated with plantar fasciitis, which occurs when the plantar fasciitis in the foot becomes inflamed. Typically, heel spurs don’t cause any symptoms. However, they can produce chronic or intermittent heel pain. Those who have had the condition often describe the irritation as a stabbing pain.
There are risk factors that may make you more likely to develop heel spurs. People who have abnormal walking gaits, run and jog on hard surfaces, are obese, or wear poorly fitting shoes are more likely to develop heel spurs.
Fortunately, there are precautions you can take to avoid developing heel spurs. One of the best ways to do this is by wearing well-fitting shoes with shock-absorbent soles. Another preventative technique is to choose running shoes if you plan on running, and walking shoes if you plan on walking. Shoes are made for different activities and it is important to research a shoe before you purchase a pair.
The pain associated with heel spurs often decreases the more you walk. However, a recurrence of pain after an extended period of rest or walking is likely to occur with this condition. Those with severe heel spur pain may opt to go the surgical route for treatment. However, more than 90% of those with the condition get better without surgical treatment. If you have a heel spur and want to know if surgery is right for you, you should go to your podiatrist and he or she will be able to conduct a pre-surgical test or exam to determine if you are an optimal candidate for surgery.
Common Sources of Ankle Pain

Ankle pain can result from a variety of conditions that affect the bones, ligaments, and tendons supporting the joint. Sprains are one of the leading causes of ankle pain. They occur when ligaments supporting the joint are stretched or torn, due to sudden twisting or rolling of the ankle. Tendon inflammation, often linked to overuse or sports activities, may also cause persistent ankle discomfort. Arthritis, including osteoarthritis, rheumatoid arthritis, or post-traumatic arthritis, can gradually wear down the joint and produce stiffness and swelling. Fractures of the tibia, fibula, or talus bones are another source, usually accompanied by severe pain, bruising, and difficulty bearing weight. A podiatrist can evaluate the specific cause of your ankle pain, order diagnostic imaging to confirm, and recommend treatment that may range from immobilization to surgery. If you are experiencing ankle pain, it is suggested that you make an appointment with a podiatrist for an exam, diagnosis, and treatment.
Ankle pain can be caused by a number of problems and may be potentially serious. If you have ankle pain, consult with Ambrose Su, DPM from Cascade Foot Clinic. Our doctor will assess your condition and provide you with quality foot and ankle treatment.
Ankle pain is any condition that causes pain in the ankle. Due to the fact that the ankle consists of tendons, muscles, bones, and ligaments, ankle pain can come from a number of different conditions.
Causes
The most common causes of ankle pain include:
- Types of arthritis (rheumatoid, osteoarthritis, and gout)
- Ankle sprains
- Broken ankles
- Achilles tendonitis
- Achilles tendon rupture
- Stress fractures
- Bursitis
- Tarsal tunnel syndrome
- Plantar fasciitis
Symptoms
Symptoms of ankle injury vary based upon the condition. Pain may include general pain and discomfort, swelling, aching, redness, bruising, burning or stabbing sensations, and/or loss of sensation.
Diagnosis
Due to the wide variety of potential causes of ankle pain, podiatrists will utilize a number of different methods to properly diagnose ankle pain. This can include asking for personal and family medical histories and of any recent injuries. Further diagnosis may include sensation tests, a physical examination, and potentially x-rays or other imaging tests.
Treatment
Just as the range of causes varies widely, so do treatments. Some more common treatments are rest, ice packs, keeping pressure off the foot, orthotics and braces, medication for inflammation and pain, and surgery.
