BACKGROUND: Combining osteotomies and soft tissue procedures is believed to reduce sesamoids in their anatomical position and maintain long-term correction when treating hallux valgus deformity. This study determines if a radiologic association exists between a radiolucent sign and a full percutaneous adductor tendon release (PATR), including a cadaveric study and a consecutive case series. Another aim was to determine the intra- and interobserver reliability of these observations.
METHODS: A prospective observational study was made between 2018 and 2019. First, a PATR was done on cadaveric specimens and, after the procedures, dissected to correlate what was seen fluoroscopically. The clinical group included 39 feet that presented mild-to-moderate HV deformity and were treated with percutaneous osteotomies associated with PATR.
RESULTS: Observers 1 and 2 saw a radioscopic radiolucent sign in 100% of cadavers and the patient population. They also observed a triangle-shaped image with an incidence of 75%, which we have named the "triangle sign."
CONCLUSION: The triangle sign may be helpful in the intraoperative confirmation of PATR and latero-plantar capsule release using this percutaneous technique.
LEVEL OF EVIDENCE: Level II, development of diagnostic criteria.
