Study summary

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.

Read the detailed description

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.

What researchers measure

Primary outcomes

  1. 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

Secondary outcomes

  1. 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
