Correction Power of Percutaneous Adductor Tendon Release (PATR) for the Treatment of Hallux Valgus: A Cadaveric Study

Description
Summary:Osteotomies are commonly used in order to correct hallux valgus deformity. However, soft tissue structures also play an essential role in the etiology, progression, and treatment of hallux valgus (HV). The purpose of the present study was to analyze the correcting power (varus), reduction strength (sesamoid) and rotation of metatarsal and proximal phalanx after percutaneous adductor tendon release (PATR). To date, no study addresses this issue. Eleven cadaveric fresh-frozen below-the-knee cadaveric lower limbs with associated hallux valgus deformity were used. These specimens were subjected to a constant abduction force after PATR. HV and intermetatarsal angles showed statistically significant differences when comparing the preoperative and postoperative periods. PATR showed to be a reliable technique as the adductor tendon was completely released in 9 cases, and 75% released in the remaining 2 feet. The study supports that PATR provides powerful and quantifiable correction of HV deformity and can be accurately performed percutaneously.
