title: Evidence-based soft tissue rheumatology. V: plantar talalgia.
abstract: Present evidence indicates that the main cause of plantar talalgia (PT) is a noninflammatory derangement at the proximal insertion of the plantar fascia. In athletes, predisposing ankle and rear-foot biomechanical abnormalities have been identified; in nonathletes, risk factors for the condition remain controversial. PT diagnosis is largely clinical, the key findings being pain and tenderness on the plantar aspect of the rear foot. Ultrasonography is a reliable confirmatory study in doubtful cases. Therapies in PT include nonsteroidal anti-inflammatory drugs, orthotic devices, night ankle dorsiflexion splints, physiotherapy, local glucocorticoid, and extracorporeal shockwave therapy. In recalcitrant cases, surgery may be offered. Of these therapies, only local glucocorticoid, as delivered by injection or iontophoresis, has shown short-term efficacy in controlled trials. The efficacy of ankle dorsiflexion splints and extracorporeal shockwave therapy is still controversial. Thus, important knowledge gaps remain on etiology, diagnosis, and treatment of PT.
