Effectiveness of Saline Water and Lidocaine Injections for the Treatment of Intractable Plantar Keratoma
A study testing Lidocaine injection, Physiological water injection and Debridement in people with Intractable Plantar Keratoma, run by Université du Québec à Trois-Rivières at 1 site in Canada.
Trial summary
An intractable plantar keratoma (IPK) is a conical thickening of the epidermis' stratum corneum and a common cause of foot pain which can have a significant, detrimental impact on the mobility, quality of life and independence of individuals. Read more about this study

About this study
Official title: Effectiveness of Saline Water and Lidocaine Injections for the Treatment of Intractable Plantar Keratoma: A Randomised Feasibility Study
An intractable plantar keratoma (IPK) is a conical thickening of the epidermis' stratum corneum and a common cause of foot pain which can have a significant, detrimental impact on the mobility, quality of life and independence of individuals. Conservative treatments are currently offered to patients with IPK, but they are unsatisfactory since they do not offer a sufficient or permanent reduction of symptoms. The purpose of this study was the evaluation of the feasibility, safety and effectiveness of innovative treatments for intractable plantar keratoma (IPK)
- Conditions
- Intractable Plantar Keratoma
- Being tested
- Lidocaine injection, Physiological water injection, Debridement, Needle insertion
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Lidocaine injectionDrug
2% (20mg/ml) lidocaine solution
Physiological water injectionDrug
0.9% sterile sodium chloride water
DebridementProcedure or surgery
A debridement was completed using a scalpel and number 15 blade, a podiatry drill and a spherical podiatry burr.
Needle insertionProcedure or surgery
A 27-gauge needle on a 3 mL syringe was inserted at 10 to 15 degrees with the bevel facing up approaching from the IPK's right side
| Study group | Role | What they receive |
|---|---|---|
| Debridement | Active comparator | A debridement (procedure involving cleaning and removing all hyperkeratotic tissue) was completed using a scalpel and number 15 blade, a podiatry drill and a spherical podiatry burr Receives: Procedure: Debridement |
| Debridement with needle insertion | Sham comparator | A debridement was followed by the insertion of a 27-gauge needle on a 3 mL syringe that was inserted at 10 to 15 degrees with the bevel facing up approaching from the IPK's right side. The syringe was removed and the IPK was bandaged with a sterile gauze and medical tape. Receives: Procedure: Debridement; Procedure: Needle insertion |
| Debridement with physiological water injection | Placebo comparator | A debridement was followed by the insertion of a 27-gauge needle on a 3 mL syringe that was inserted at 10 to 15 degrees with the bevel facing up approaching from the IPK's right side. The podiatrist pressed completely on the syringe to inject 1 mL of 0.9% sterile sodium chloride water. The syringe was removed and the IPK was bandaged with a sterile gauze and medical tape. Receives: Drug: Physiological water injection; Procedure: Debridement |
| Debridement with lidocaine injection | Experimental | A debridement was followed by the insertion of a 27-gauge needle on a 3 mL syringe that was inserted at 10 to 15 degrees with the bevel facing up approaching from the IPK's right side. The podiatrist pressed completely on the syringe to inject 1 mL of 2% lidocaine solution. The syringe was removed and the IPK was bandaged with a sterile gauze and medical tape. Receives: Drug: Lidocaine injection; Procedure: Debridement |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change from baseline in pain (visual analogue scale)
Patients were asked to rate their pain level during the seven previous days on the visual analogue scale (VAS). The VAS is a 10 centimeters line anchored at the beginning by "no pain" and at the end by "worst pain imaginable"
Measured: Baseline, 4 weeks, 8 weeks, 12 weeks, 6 months, 12 months
Change from baseline in Foot-Function-Index-Revised (FFI-R)
The Foot Function Index (FFI) measure the impact of foot pathology on function in terms of pain, disability and activity restriction
Measured: Baseline, 4 weeks, 8 weeks, 12 weeks, 6 months, 12 months
Secondary outcomes (1)
Change from baseline in size of Intractable plantar keratoma
IPK's length and width was measured with a millimeter scale ruler used in wound care (accuracy ± 0.1 mm). The depth was estimated with a cotton tip applicator technique measured with the same ruler
Measured: Baseline, 4 weeks, 8 weeks, 12 weeks, 6 months, 12 months

Questions about this trial
What is this clinical trial studying?
A study testing Lidocaine injection, Physiological water injection and Debridement in people with Intractable Plantar Keratoma, run by Université du Québec à Trois-Rivières at 1 site in Canada.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 2 Mar 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change from baseline in pain (visual analogue scale) (time frame: Baseline, 4 weeks, 8 weeks, 12 weeks, 6 months, 12 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04777227, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Mar 2021.
