Efficacy and safety of condylectomy with minimally invasive surgery in the treatment of interdigital corns of the lesser toes compared to conservative treatment.

BACKGROUND: Minimally invasive surgery (MIS) procedures cause less trauma to the patient and might improve recovery. This study aimed to determine the efficacy and safety of condylectomy with MIS to treat interdigital corns of the lesser toes. METHODS: This prospective cohort study was conducted in seven podiatry centers. Patients with interdigital corns of the lesser toes, progressing for more than a year, with one or more recurrences in the last year following conservative treatments were eligible. The recruited patients were classified according to their treatment: conservative or surgical (condylectomy with MIS) and were compared. Patient satisfaction, pain, the clinical and functional status of the foot and the appearance of sequelae were assessed at 3 and 6 months after treatment. RESULTS: At 6 months, patients in the surgical treatment group showed no pain on pressure, which significantly differed from the conservative treatment group (p <  0.001). They also improved clinical and functional status of the foot, reaching values comparable to those of the standard population. No paresthesia, joint stiffness or instability, toe malalignment, or corn transfer to a contiguous site resulted from the surgical treatment. CONCLUSIONS: Condylectomy with MIS is effective and safe to treat interdigital corns of the lesser toes.

Description of the surgical technique for condylectomy with minimally invasive surgery to treat interdigital helomas on the lesser toes: a Delphi study.

BACKGROUND: Descriptions of the techniques for condylectomies via minimally invasive surgery (MIS) to treat interdigital helomas of the lesser toes are scarce in the literature. This study aimed to define and describe this surgical technique. METHODS: This observational study was performed using the Delphi method. We collected the anonymous opinions of a multidisciplinary international panel of ten experts by answering a 43-items questionnaire via e-mail. Statements with an average score ≥ 3 were included in the next round, as were those in which none of the three statements reached the minimum score of 3 within the same item. RESULTS: Response rate: 90%. Three rounds were needed to reach consensus on proposed items. A new statement that combined two statements was proposed in round 3. Eleven recommendations regarding the incision and instruments used to perform this surgical technique were obtained based on the expert consensus. CONCLUSIONS: A longitudinal incision to the distal pulp of the toe or an incision to the centre of the plantar aspect of the head of the proximal phalanx should be performed according to the affectation, and a Beaver 64 scalpel blade, a blunt elevator and a Shannon-Isham burr are the most acceptable tools for this kind of surgery.
