An interventional study of Baxter's Nerve Pulsed Radiofrequency and Autologous Platelet-Rich Plasma Injection in Plantar Fasciitis, Heel Pain and Nerve Compression Syndromes, sponsored by Assiut University. Not yet recruiting. Open to participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2026-09-17.
Sponsored by Assiut University · Not applicable, Interventional, and Treatment
Plantar fasciitis is a common condition causing chronic heel pain due to degenerative changes in the tissue supporting the arch of the foot. While most patients improve with conservative care such as physical therapy, anti-inflammatory medications, and orthotics, approximately 10% to 20% experience chronic pain that fails to respond to standard measures. In up to 20% of these persistent cases, irritation or entrapment of the first branch of the lateral plantar nerve (Baxter's nerve) also plays a key role in the pain.
The purpose of this study is to compare the safety and effectiveness of three ultrasound-guided interventional approaches for treating chronic recalcitrant plantar fasciitis:
A total of 75 adult patients aged 18 to 65 years with recalcitrant plantar fasciitis persisting for over 6 months will be randomly assigned into three equal groups (25 patients per group). Participants and independent clinical assessors will be blinded to treatment allocation. Patients will be followed for 6 months to evaluate pain reduction, functional recovery, plantar fascia thickness measured by ultrasound, and procedure safety.

This study's planned enrollment of 75 is above the median of 56 across 194 interventional studies indexed under Fasciitis, Plantar.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Participants receive ultrasound-guided pulsed radiofrequency (PRF) targeting Baxter's nerve (the first branch of the lateral plantar nerve). The procedure is performed under complete aseptic technique at 42°C, with a pulse width of 20 ms, a frequency of 2 Hz, for a duration of 8 minutes.
Procedure: Baxter's Nerve Pulsed Radiofrequency
Participants receive an ultrasound-guided injection of 5 mL autologous platelet-rich plasma (PRP) into the diseased plantar fascia. PRP is prepared via a standardized double-spin centrifugation technique and administered under complete aseptic precautions.
Procedure: Autologous Platelet-Rich Plasma Injection
Participants receive combined treatment consisting of ultrasound-guided Baxter's nerve pulsed radiofrequency (42°C, 20 ms pulse width, 2 Hz for 8 minutes) followed by ultrasound-guided autologous platelet-rich plasma injection (5 mL) into the diseased plantar fascia under complete aseptic technique.
Procedure: Baxter's Nerve Pulsed Radiofrequency · Procedure: Autologous Platelet-Rich Plasma Injection
Ultrasound-guided pulsed radiofrequency (PRF) targeting Baxter's nerve (the first branch of the lateral plantar nerve) performed under sterile aseptic precautions. Parameters applied: target temperature of 42°C, pulse width of 20 ms, frequency of 2 Hz, for a total duration of 8 minutes.
Ultrasound-guided administration of 5 mL autologous platelet-rich plasma (PRP) directly into the hypoechoic, thickened portion of the diseased plantar fascia. PRP is isolated using a standardized double-spin centrifugation protocol and injected under complete aseptic conditions.
Change from Baseline in Visual Analogue Scale (VAS) Pain Score
Pain intensity is assessed using the Visual Analogue Scale (VAS), where patients rate their heel pain on a 0 to 10 scale (0 = no pain, 10 = worst imaginable pain). Lower scores indicate less pain and better clinical improvement. The score change will be calculated as the post-treatment score minus the baseline score.
Time frame: Baseline and 6 months post-intervention
No study locations are listed for this record.
Start is estimated for Oct 2026; primary completion for Oct 2027, 12 months later.
Of 104 non-industry interventional studies with no phase under Fasciitis, Plantar, half reached primary completion within 11 months of starting (the median), counting those still running; a quarter within 6 and three quarters within 21. This study's planned 12 months is close to that.
Counting every sponsor, half of 109 studies reached it within 11 months; a quarter within 6 and three quarters within 22.
