Clinical outcomes of selective plantar fascia release for hallux interphalangeal joint ulcers.

BACKGROUND Plantar hallux IPJ ulcers are common and challenging to manage, with many available treatments. One newer technique called SPFR has been used in the management of plantar forefoot ulcers. OBJECTIVE This case series reports the clinical results of SPFR for treatment of strictly plantar hallux IPJ ulcers. MATERIALS AND METHODS A retrospective chart review was conducted on patients that underwent SPFR procedure by a single foot and ankle surgeon from 2018 to 2023. The primary study outcome was to identify the rate and time of healing associated with SPFR for hallux IPJ ulcers. Only the initial surgery was evaluated for time of healing for the ulcer, healing rate, and complications. Subsequent surgeries were reviewed as well. Patient charts were further reviewed to determine the presence or absence of a postoperative complication. RESULTS A total of 17 feet from 17 patients were studied. The hallux IPJ ulcers healed in an average of 3.0 months. The average follow-up time was 26.9 months. Fifteen patients (88.2%) healed after the SPFR procedure. Five patients (29.4%) developed transfer lesions, and 7 patients (41.2%) developed postoperative complications. CONCLUSIONS The authors believe that SPFR can be utilized in the treatment of hallux IPJ ulcers if both surgeons and patients are aware of the potential complications and limitations of this procedure. Further research is warranted to evaluate the efficacy and reproducibility of these results.
