A novel closed technique for ultrasound-guided plantar fascia release with a needle: review of 107 cases with a minimum follow-up of 24 months

Abstract

Abstract Background This study aims to analyze the clinical outcome of a new ultrasound-guided surgery for partial plantar fasciotomy performed with a needle for treatment of plantar fasciitis. Methods We performed a retrospective review of 107 patients diagnosed with plantar fasciitis who underwent ultrasound-guided release of the plantar fascia. The series included 62 males (57.9%) and 45 females (42.1%) treated between April 2014 and February 2018, with a mean follow-up of 21.05 ± 10.96 months (7–66) and a minimum follow-up of 24 months. The mean age was 48.10 ± 10.27 years (27–72). Clinical assessments and ultrasound examination were carried out before treatment, after 1 week, and then after 1, 3, 12, and 24 months. The clinical assessment was based on a visual analog scale and the Foot and Ankle Disability Index. Results Heel pain improved in 92.5% (99) of patients, but not in 7.4% (8 patients). In the group of patients whose heel pain improved, 9 experienced overload on the lateral column and dorsum of the foot, which improved with the use of plantar orthoses and a rehabilitation program. We recorded no nerve complications (e.g., paresthesia), vascular injuries, or wound-related problems. Conclusion Ultrasound-guided partial plantar fasciotomy with a needle is safe, since structures are under direct visualization of the surgeon and the risk of damage is minimal. Stitches are not necessary, and recovery is fast. Consequently, costs are low, and the patient can return to work quickly. This technique may represent a valid option for treatment of plantar fasciitis.
