Effectiveness of Saline Water and Lidocaine Injections for the Treatment of Intractable Plantar Keratoma

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)

Inclusion criteria

  • Having a painful IPK for at least 3 months

Exclusion criteria

  • Ongoing pregnancy or breastfeeding
  • Severe cardiovascular or neurological disease
  • Immunosuppressed status
  • Presence of a plantar ulcer
  • Allergy to lidocaine
  • History of keloid or hypertrophic scar
  • Simultaneous painful plantar syndrome unrelated to the presence of an IPK

Treatment and study plan

Lidocaine injection

Drug

2% (20mg/ml) lidocaine solution

Physiological water injection

Drug

0.9% sterile sodium chloride water

Debridement

Procedure

A debridement was completed using a scalpel and number 15 blade, a podiatry drill and a spherical podiatry burr.

Needle insertion

Procedure

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

Primary outcomes

  1. Change from baseline in pain (visual analogue scale)

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

    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"

  2. Change from baseline in Foot-Function-Index-Revised (FFI-R)

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

    The Foot Function Index (FFI) measure the impact of foot pathology on function in terms of pain, disability and activity restriction

Secondary outcomes

  1. Change from baseline in size of Intractable plantar keratoma

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

    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
