Abstract
Introduction
Plantar fasciopathy is a common cause of heel pain, and is usually treated in primary practice with conservative measures. Intractable cases can prove very difficult to treat. Currently plantar fasciopathy is not routinely imaged and treatment is empirical. At the Royal Surrey County Hospital patients with intractable plantar fasciopathy are managed in a unique ‘one-stop’ Heel Pain clinic. Here they undergo clinical assessment, ultrasound scanning and targeted therapy.
Methods
Patients referred to the clinic since 2009, with symptoms lasting longer than 6 months and failed conservative management, were prospectively followed. Plantar fasciopathy was confirmed on ultrasound scanning. The ultrasound scans were used to classify the disease characteristics of the plantar fascia.
Results
125 feet (120 patients) were found to have plantar fascia disease. Ultrasound scans demonstrated 64% with typical insertional pathology only. The remaining 36% had atypical distal fascia involvement, with either pure distal disease or a combination of insertional and distal disease. Patients with atypical distal disease were found to have either distal thickening or discrete fibromata.
Conclusion
The high proportion of atypical (non-insertional) disease in this cohort shows that ultrasound scanning is valuable in determining location and characterising the pathology in the plantar fascia. Atypical pathology would otherwise not be detected.
We propose a new classification for plantar fasciopathy; insertional fasciopathy or non-insertional fasciopathy. This is in keeping with current classification of achilles tendinopathy. The main benefit of this Guildford Classification is in determining optimum treatments for recalcitrant plantar fasciopathies. Empirical treatment is not adequate for recalcitrant cases.
