An interventional study of Ultrasound-Guided Baxter Nerve Injection and Ultrasound-Guided Flexor Digitorum Brevis Origin Injection in Plantar Heel Pain, Plantar Fasciosis and Calcaneal Spur, sponsored by Kutahya Health Sciences University. Completed at 1 site in Turkey (Türkiye). Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-10-20.
Sponsored by Kutahya Health Sciences University · Not applicable, Interventional, and Treatment
This study compared three ultrasound-guided injection approaches for patients with plantar heel pain associated with a calcaneal spur: injection around the Baxter nerve, injection at the origin of the flexor digitorum brevis muscle, and a combined injection at both sites. The study assessed pain and foot function before treatment and at 1, 3, and 6 months after treatment to compare the outcomes of the three approaches.
This was a prospective, single-center, randomized controlled trial involving 210 patients with plantar heel pain associated with a calcaneal spur. Participants were randomly assigned in a 1:1:1 ratio to one of three ultrasound-guided injection groups: Baxter nerve injection, injection at the origin of the flexor digitorum brevis (FDB) muscle, or combined injections at both sites.
Pain intensity and foot function were assessed at baseline and at 1, 3, and 6 months after treatment using the Visual Analog Scale (VAS) and the Foot Function Index (FFI). The outcomes of the three treatment groups were compared over follow-up.
A total of 202 participants completed follow-up; 8 participants did not attend follow-up. The study aimed to compare clinical outcomes between the three injection approaches in patients with plantar heel pain associated with a calcaneal spur.
28 studies on the registry are indexed under Heel Spur; 8 are open to participants now.
This study's enrollment of 210 is above the median of 60 across 22 interventional studies indexed under Heel Spur.

Exclusion Criteria:
Participants received an ultrasound-guided injection targeting the Baxter nerve, with a total injection volume of 2 mL at the target site.
Procedure: Ultrasound-Guided Baxter Nerve Injection
Participants received an ultrasound-guided injection at the origin of the flexor digitorum brevis muscle, with a total injection volume of 2 mL at the target site.
Procedure: Ultrasound-Guided Flexor Digitorum Brevis Origin Injection
Participants received ultrasound-guided injections at both the Baxter nerve and the origin of the flexor digitorum brevis muscle, with a total injection volume of 1 mL at each site.
Procedure: Combined Ultrasound-Guided Baxter Nerve and Flexor Digitorum Brevis Injections
Ultrasound-guided injection targeting the Baxter nerve for plantar heel pain associated with a calcaneal spur. The injection was administered at the Baxter nerve target site.
Ultrasound-guided injection at the origin of the flexor digitorum brevis muscle for plantar heel pain associated with a calcaneal spur.
Combined ultrasound-guided injections targeting both the Baxter nerve and the origin of the flexor digitorum brevis muscle for plantar heel pain associated with a calcaneal spur.
Visual Analog Scale (VAS) for Heel Pain
Change in heel pain intensity measured using the Visual Analog Scale (VAS). Scores were assessed at baseline and at 1, 3, and 6 months after injection.
Time frame: Baseline, 1 month, 3 months, and 6 months after injection
Foot Function Index (FFI)
Change in foot-related pain and functional disability measured using the Foot Function Index (FFI). Scores were assessed at baseline and at 1, 3, and 6 months after injection.
Time frame: Baseline, 1 month, 3 months, and 6 months after injection
