BACKGROUND:The treatments of plantar fasci tis as an important cause of calcaneodynia are different in medical institutions, as wel as the therapeutic results.
OBJECTIVE:To summarize various treatments of plantar fascia, and based on the pathogenesis and pathological mechanics of plantar fasci tis, to investigate the effect of various treatment methods and indications.
METHODS:A computer-based online search of PubMed database and Wanfang database was performed for articled related to plantar fasci tis published between January 1993 and January 2014. The keywords were
“plantar fasci tis, mechanism, treatment”in English and Chinese, respectively, by screening the titles and abstracts. Final y, 34 articles were included in result analysis.
RESULTS AND CONCLUSION:The treatment of plantar fasci tis needs to fol ow the principle from noninvasive to invasive treatment. Stretching the plantar fascia and heel cord, using prefab-ricated orthotics, and wearing night splints are crucial for the treatment of plantar fasci tis. Local hormone injection can be used as first-line therapy for patients with acute plantar fasci tis if they can tolerate the adverse reactions due to hormone therapy. Platelet-rich plasma therapy has a promising prospect, but there is lack of experimental evidences. Extracorporeal shock wave therapy can be a choice for recurrent chronic intractable plantar fasci tis. Surgical intervention remains the last line of therapy, for which, rigorous screening is important, but it is not always effective at reducing pain.
