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)

2% (20mg/ml) lidocaine solution
0.9% sterile sodium chloride water
A debridement was completed using a scalpel and number 15 blade, a podiatry drill and a spherical podiatry burr.
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

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"
Time frame: 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
Time frame: Baseline, 4 weeks, 8 weeks, 12 weeks, 6 months, 12 months
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
Time frame: Baseline, 4 weeks, 8 weeks, 12 weeks, 6 months, 12 months
