Metatarsal tendonitis is one of the most common causes of heel pain, mostly in the middle-aged and elderly population, due to degenerative changes of the metatarsal tendon membrane at the beginning of the heel bone from repeated trauma. Etiology: In 85% of patients, the cause is unknown. External irritants such as walking and running can lead to small tears at the beginning of the metatarsal tendon membrane. Degenerative changes occur with or without fibroplasia and chronic inflammation. In athletes, common etiologies include overtraining, wearing unsuitable shoes, and a sudden increase in training volume. In the elderly, common etiologies include: weakness of the muscles within the foot, loss of muscle strength, and flat feet. How to determine if it is metatarsal tendonitis: 1. Pain in the first few steps in the morning, or standing up again while sitting and resting is the most painful. 2.The pain occurs after weight-bearing activities. 3.The pain disappears after a few steps of walking. 4. The location of the pain varies, but is ultimately at the medial tuberosity of the heel bone. 5. The pain is aggravated and intense during weight-bearing activities, and the symptoms can be induced after a lot of activities. Treatment options: 2. Basic treatment should include rest and avoidance of strenuous exercise. 3.ESWT extracorporeal shock wave therapy (shock wave therapy) has a good analgesic effect, and the effective rate reaches 80% after a course of treatment. 4.Wearing suitable shoes: 5.Supporting aid: Only 30% of commercially available insoles are effective, custom-made insoles can support the foot to the maximum extent and bring better treatment effect. 6.Stretching and strength exercises: stretching the posterior calf muscle group – stretching exercises using walls and steps; stretching the metatarsal tendon membrane – foot massage treatment method of stepping on beverage cans and tennis balls; in addition, there are hand towel exercises with toe grip to improve the strength of the intrinsic muscles of the foot. (Figure) 7, night splint and walking support: night splint is used to stretch the calf muscles and metatarsal tendon membrane to help restore the metatarsal tendon membrane, but the effect is uncertain. Walking supports: reduce heel impact and support the arch of the foot, the effectiveness is 46% 8, anti-inflammatory drug therapy: non-steroidal anti-inflammatory drug therapy (NSAIDs).
