Plantar fasciosis is pain at the site of the attachment of the plantar fascia and the calcaneus (calcaneal enthesopathy), with or without accompanying pain along the medial band of the plantar fascia. Diagnosis is mainly clinical. Treatment involves calf muscle and plantar soft-tissue foot-stretching exercises, night splints, orthotics, and shoes with appropriate heel elevation. Syndromes of pain in the plantar fascia have been called plantar fasciitis; however, because there is usually no inflammation, plantar fasciosis is more correct. Other terms used include calcaneal enthesopathy pain or calcaneal spur syndrome; however, there may be no bone spurs on the calcaneus. Plantar fasciosis may involve acute or chronic stretching, tearing, and degeneration of the fascia at its attachment site.
Inappropriate footwear is the No. 1 cause of plantar fasciosis. Footwear that possesses toe spring and a tapered toe box holds your big toe in an adducted and extended position. In this position, your abductor hallucis muscle-the muscle responsible for moving your big toe away from your foot’s midline-pulls on a foot structure called the flexor retinaculum and may restrict blood flow through your posterior tibial artery, the vessel that carries blood to the bottom of your foot. Tissues in the sole of your feet begin to degenerate as blood supply to this area is decreased. Other recognized causes of or contributors to this health problem include the following, calf muscle shortening, plantar fascia contracture, Obesity, rheumatoid arthritis, reactive arthritis, Psoriatic arthritis, Corticosteroid injections.
The most common symptoms of plantar fasciitis include pain on the bottom of the foot near the heel, pain with the first few steps after getting out of bed in the morning, or after a long period of rest, such as after a long car ride. The pain subsides after a few minutes of walking. Greater pain after (not during) exercise or activity.
Your doctor will ask you about the kind of pain you’re having, when it occurs and how long you’ve had it. If you have pain in your heel when you stand up for the first time in the morning, you may have plantar fasciitis. Most people with plantar fasciitis say the pain is like a knife or a pin sticking into the bottom of the foot. After you’ve been standing for a while, the pain becomes more like a dull ache. If you sit down for any length of time, the sharp pain will come back when you stand up again.
Non Surgical Treatment
Give your painful heel lots of rest. You may need to stay completely off your foot for several days when the pain is severe. Your healthcare provider may recommend or prescribe anti-inflammatory medicines, such as aspirin or ibuprofen. These drugs decrease pain and inflammation. Adults aged 65 years and older should not take non-steroidal anti-inflammatory medicine for more than 7 days without their healthcare provider’s approval. Resting your heel on an ice pack for a few minutes several times a day can also help. Try to cushion your foot. You can do this by wearing athletic shoes, even at work, for awhile. Heel cushions can also be used. The cushions should be worn in both shoes. They are most helpful if you are overweight or an older adult. Your provider may recommend special arch supports or inserts for your shoes called orthotics, either custom-made or off the shelf. These supports can be particularly helpful if you have flat feet or high arches. Your provider may recommend an injection of a cortisone-like medicine. Lose weight if needed. A night splint may be recommended. This will keep the plantar fascia stretched while you are sleeping. Physical therapy for additional treatments may be recommended. Surgery is rarely needed.
Surgery is considered only after 12 months of aggressive nonsurgical treatment. Gastrocnemius recession. This is a surgical lengthening of the calf (gastrocnemius) muscles. Because tight calf muscles place increased stress on the plantar fascia, this procedure is useful for patients who still have difficulty flexing their feet, despite a year of calf stretches. In gastrocnemius recession, one of the two muscles that make up the calf is lengthened to increase the motion of the ankle. The procedure can be performed with a traditional, open incision or with a smaller incision and an endoscope, an instrument that contains a small camera. Your doctor will discuss the procedure that best meets your needs. Complication rates for gastrocnemius recession are low, but can include nerve damage. Plantar fascia release. If you have a normal range of ankle motion and continued heel pain, your doctor may recommend a partial release procedure. During surgery, the plantar fascia ligament is partially cut to relieve tension in the tissue. If you have a large bone spur, it will be removed, as well. Although the surgery can be performed endoscopically, it is more difficult than with an open incision. In addition, endoscopy has a higher risk of nerve damage.
Calf stretch. Lean forward against a wall with one knee straight and the heel on the ground. Place the other leg in front, with the knee bent. To stretch the calf muscles and the heel cord, push your hips toward the wall in a controlled fashion. Hold the position for 10 seconds and relax. Repeat this exercise 20 times for each foot. A strong pull in the calf should be felt during the stretch. Plantar fascia stretch. This stretch is performed in the seated position. Cross your affected foot over the knee of your other leg. Grasp the toes of your painful foot and slowly pull them toward you in a controlled fashion. If it is difficult to reach your foot, wrap a towel around your big toe to help pull your toes toward you. Place your other hand along the plantar fascia. The fascia should feel like a tight band along the bottom of your foot when stretched. Hold the stretch for 10 seconds. Repeat it 20 times for each foot. This exercise is best done in the morning before standing or walking.
