Ultrasound-guided procedures for plantar fasciitis: a randomized clinical study

Abstract

Abstract Background Corticosteroid injections are commonly used for the treatment of plantar fasciitis. In recent years, ultrasound-guided multipuncture treatment of the fascia has been described in the literature. Our study aimed to compare the effectiveness of these two techniques in the treatment of plantar fasciitis. Methods The outcomes achieved over 120 days following the use of these techniques to treat plantar fasciitis were examined. A total of 81 patients were randomly selected for the study; 41 were treated with ultrasound-guided multipuncture and 40 with ultrasound-guided corticosteroid injection. Clinical examinations and ultrasound assessments were performed before treatment and at 30, 60 and 120 days post-treatment. Clinical assessments included the use of a visual analog scale (VAS) to record pain and the Foot Function Index (FFI) to evaluate function. Ultrasound was used to measure the thickness of the plantar fascia. Results Both the ultrasound-guided multipuncture and corticosteroid injection techniques were associated with significant functional and echographic improvements at 4 months post-treatment (P < 0.001). Pain did not improve significantly after 120 days with ultrasound-guided corticosteroid injection, whereas significant pain reduction was observed with ultrasound-guided multipuncture. Conclusion Corticosteroid injection provides better short-term results in terms of VAS pain and FFI scores. However, ultrasound-guided multipuncture shows superior outcomes in VAS pain and FFI scores at 120 days.
