Pain in the back of the foot is usually thought of as being caused by a bone spur in the heel bone, but the spur itself does not cause pain in the back of the foot, only if the irritation causes plantar fasciitis. Generally speaking, plantar heel pain can be caused by plantar fasciitis, regardless of the cause. The plantar fascia is a part of the plantar tendon membrane, which is a tendinous thickening of the central part of the plantar deep fascia, originating from the medial eminence of the calcaneal tuberosity, and plays an important role in maintaining the arch of the foot. In the rhythmic stress of repeated traction such as long-distance running, jumping sports, as well as cross-country, over the obstacle, formation, especially the orthopedic training and other military training, as well as long-term sustained standing and so on to make the anterior part of the plantar foot weight-bearing increase, resulting in the metatarsal muscle belly and the surface of the tendons of the dense connective tissues because of the excessive activity, traction, extrusion and caused by the fascia ischemia, metatarsal tendon membrane and the Achilles node attachment of the occurrence of chronic fibrotic tissue inflammation, and the formation of spurs later, was packaged In the beginning of the metatarsal tendon membrane, this bone spur can cause bunion, short toe flexor and metatarsal tendon membrane medial tension increase, or cause synovial bursitis, heel pain is called metatarsalgia, also known as metatarsalgia. Modern medicine believes that when the metatarsal fascia is subjected to forces exceeding its physiological limits, this repeated long-term overload will induce inflammation, degeneration and fibrosis, resulting in metatarsal fasciitis. Over time, the contracture of the metatarsal fascia causes persistent pulling injury at the heel bone attachment, and the fibers of the ligaments and fascia are constantly being torn, and the body’s efforts to strengthen this area cause calcium salt deposition and ossification at the attachment and the formation of bone spurs. Typical symptoms are the gradual onset of pain in the sole of the heel and the ball of the foot when standing and walking in the morning or after a long period of rest. Physical examination may show the pressure pain of the entire metatarsophalangeal fascia, which is obvious at the medial part of the heel tuberosity, and the pain and pressure pain of the toes and ankle joints are more obvious when passive dorsiflexion is performed. Acute injuries mostly have a history of trauma, such as walking on the foot suddenly stepped on a hard object or downstairs when the foot followed the ground too violently, chronic injuries are mostly seen in the middle-aged and elderly people over 40, women are more common than men, the onset of the disease is slow, and there may even be a history of a few years, the clinical manifestations of the plantar pain, do not dare to walk, the examination can be seen in the middle of the plantar pressure pain is obvious, refuses to be pressed and claudication. Treatment: Non-surgical treatment: Commonly used non-surgical treatments include: shoe inserts and padding, orthopedic shoes, physical factor therapy, pulling therapy, oral non-steroidal anti-inflammatory and analgesic drugs, local closure of the pressure points, extracorporeal shockwave therapy, local injection of botulinum toxin and so on. Local closure therapy: first of all, the injection point is localized, with the pressure point as the injection point, routine iodine, alcohol disinfection, spreading the towel, the left thumb presses the pain point, the right hand holds the needle into the general local feeling of soreness, after withdrawing no blood, injected with 2% Lidocaine + Prednisolone Acetate + Vitamin B1 + Vitamin 12 mixture, each pain point is injected with the mixture of 3-4 ml, 5 minutes of local massage after the injection. Once a week, generally 2-3 times of injection is appropriate, avoid strenuous activities during the treatment. Topical ointment: According to Chinese medicine, the etiology of metatarsophalangeal fasciitis is kidney deficiency, cold and dampness. Foot in the lower and more cold and damp, kidney yin and yang deficiency leads to the deficiency of positive qi, cold and dampness of the evil take advantage of the weakness of the entry, stagnation in the lower, resulting in the stagnation of the tendons and veins, blood stasis internal obstruction, not through the pain of the treatment of the ideal method is the external cream, external plasters paste on the heel muscle surface to stimulate nerve endings, dilate blood vessels, promote local blood circulation, improve the nutrition of the surrounding tissues, to achieve the purpose of the swelling, anti-inflammatory and analgesic. Nerve block: At the midpoint of the line between the head of the fibula and the neck of the fibula, the common peroneal nerve can be touched and rolled on the neck of the fibula when the finger slides on the skin surface. After sterilization, the operator fixes the common peroneal nerve between the middle finger and the index finger of the left hand, and the right hand holds a short 3 cm long 7-gauge needle to puncture towards the bone. When the peroneal neck is punctured, there is usually an abnormal sensation; if there is no abnormal sensation, the drug can also be injected at this point. A tibial nerve block is then performed at the ankle, and the posterior tibial artery is identified at the posterior aspect of the medial ankle. The operator presses the artery under the fingers of the left hand, and the right hand holds a short 3 cm long 7-gauge needle directly along the edge of the fingers to puncture the posterior border of the posterior tibial artery. If there is no abnormal sensation, the needle can be inserted all the way to the bone and then retracted 0.5~1.0 cm to inject the drug. Injectable drugs: bupivacaine, triamcinolone acetonide, vitamin B12. Surgical treatment: Through non-surgical treatment, most of the patients’ symptoms can be relieved within 12 months, but there are still 10% of the patients with unsatisfactory results, and about 5% of the patients need to undergo surgical treatment, which mostly involves resection of bone spurs.
