Percutaneous surgery of the forefoot compared with open technique - Functional results, complications and patient satisfaction.

BACKGROUND

The use of percutaneous surgery is currently very common in foot and ankle surgery. The following prospective open-label patient-preference based study compares the traditional open technique versus the percutaneous surgery technique.

METHODS

The current study describes the results of 287 patients operated due to forefoot deformities either by open surgery or percutaneously. 96 of them underwent hallux valgus corrective surgery. The rest had lesser toe deformities. They were followed for a period of up to 24 months, to assess the surgery related pain, complications, and patient satisfaction. 112 patients were operated using a conventional open technique were compared to 175 patients treated using a percutaneous technique. Technique choice was left to the patient preference, though older patients with disturbed blood flow, were advised to undergo percutaneous surgery.

RESULTS

There is less pain using the percutaneous techniques relative to the open technique during the first 6 post-operative weeks. The 6, and 24 months FAOS score is similar in both groups. Complications are rare in any of the groups, with a significantly higher ASEPSIS score in the open surgery group.

CONDCLUSIONS: Percutaneous forefoot surgery appears safe and efficacious, demonstrating equal radiographic (in a 96 strong cohort of hallux valgus patients) and clinical results at six and 24 months. Due to less post-operative pain, and less infection risk it appears that percutaneous techniques are superior to open technique in some respects of treatment and indeed the PGIC of patients was significantly higher in this group.
