From the Research

Surgical treatment is the most effective approach for interdigital cysts, with a high cure rate of 95% as reported in the study by 1.

Overview of Surgical Rupture Treatment

Surgical rupture treatment for interdigital cysts involves a minor surgical procedure to drain and treat these painful lesions that occur between the toes. The procedure typically begins with proper cleaning and disinfection of the affected area, followed by local anesthesia using lidocaine 1-2% to numb the region.

Key Steps in the Procedure

  • The surgeon then makes a small incision into the cyst using a sterile scalpel, allowing the accumulated fluid to drain completely.
  • After drainage, the cavity is usually flushed with sterile saline solution to remove any remaining debris or bacteria.
  • The wound may be left open to heal by secondary intention or closed with a few sutures depending on the size and depth of the cyst.

Post-Operative Care

  • Post-operative care includes daily cleaning with antiseptic solution like chlorhexidine 0.05%, application of topical antibiotics such as mupirocin or bacitracin, and covering with a sterile dressing for 5-7 days.
  • Oral antibiotics like cephalexin 500mg four times daily for 7-10 days may be prescribed if infection is present.
  • Patients should elevate the foot when possible, avoid putting weight on the affected area for 24-48 hours, and wear loose, comfortable footwear until healing is complete.

Effectiveness and Considerations

This surgical approach is effective because it provides immediate relief by removing the accumulated fluid and allows for direct treatment of any underlying infection, though recurrence is possible if the root cause (such as biomechanical issues or repeated trauma) isn't addressed, as supported by the findings in 1. Other studies, such as 2, also highlight the importance of complete removal of the cyst wall to avoid relapses. While there are various treatment modalities available, surgery yields the highest cure rate among all treatment modalities, making it the preferred choice for interdigital cysts, as noted in 1.
