Comparison of the Effectiveness of USG and Palpation Guidance Steroid Injection in Patients With Plantar Fasciitis

Overview

Plantar fasciitis, often described as overloading of the plantar fascia, is the most common cause of heel pain in adults. It is characterized by a sharp pain along the medial aspect of the heel, which is worse with the first step taken in the morning or at the beginning of an activity and decreases as the person warms up. The etiology of plantar fasciitis is multifactorial and not well understood. Poor biomechanics and changes in the structure of the foot can lead to repeated micro-trauma at the beginning of the plantar fascia, causing inflammation and degeneration. Plantar fasciitis is more common in sedentary individuals and athletes and those participating in running sports. Other risk factors associated with plantar fasciitis include reduced ankle dorsiflexion, increased body mass index (BMI), and work-related weight loss activities. Current treatments for plantar fasciitis, such as plantar fascia stretching exercises, strapping, extracorporeal shock wave therapy, nonsteroidal anti-inflammatory drugs (NSAIDs), arch braces, and heel pads are mainly aimed at reducing inflammation. Corticosteroid injections are usually reserved for refractory plantar fasciitis after conservative noninvasive attempts have failed. It has been shown to effectively reduce heel pain in patients with plantar fasciitis. The strong anti-inflammatory effect of corticosteroids can speed up the process of pain relief. In our study, we aimed to compare the effectiveness of USG and palpation guidance blind steroid injection in patients diagnosed with plantar fasciitis.

It is planned to enroll 60 (sixty) patients in the study. Patients diagnosed with plantar fasciitis, between the ages of 18-75, who have failed conservative treatment (stretching exercises, non-steroidal anti-inflammatory drugs and heel pads) for at least 3 months, and those with a Visual Anolog Scale value of 5 and above will be included in the study. Any local injection therapy and physical therapy for heel pain in the last 4 months, any surgery history for heel pain, history of tarsal tunnel syndrome, ankle effusion showing intra-articular disease, healed calcaneal fracture, Achilles tendinopathy, foot including pes and any deformity of the ankle, planus or pes cavus deformity; Patients with systemic disorders such as diabetes mellitus, rheumatoid arthritis, hematological disease or gout, pregnancy, history of aspirin or aspirin-like medication, and mental insufficiency will be excluded from the study. In the study, the patients will be filled in Visual Analogue Scale (VAS) and Foot Function Indez (FFI) questionnaires. Patients will be randomized into 2 groups according to the Random Number Generation. The first group will be the USG-guided steroid injection group, and the second group will be the palpation-guided steroid injection group. In the USG-guided group, steroid injection will be made to the area where the fascia is thickened under the guidance of USG. In the palpation-guided group, the most painful point will be found by palpation on the calcaneus bone and steroid injection will be made to that part. The content of the steroid solution will be 1 ml of 1% Lidocaine + 1 ml (40 mg) methylprednisolone. There will be pre-injection, 1st month and 3rd month controls after injection.
