Radiographic and Clinical Outcomes of Intramedullary Nails in the Modified Lapidus Procedure: A Retrospective Comparison with Dorsomedial Locking Plates.

ABSTRACT:

Background

The Lapidus procedure evolved into the first tarsometatarsal (TMT) arthrodesis, primarily used for treating severe hallux valgus, particularly in TMT arthritis or instability. Although effective, early techniques have high nonunion rates. Recent developments, including locking plate (LP) and intramedullary nail (IN) use, are aimed at enhancing fixation. LPs enable early weightbearing but may cause symptomatic hardware irritation. We hypothesized that IN fixation would yield better clinical and radiologic outcomes and fewer complications than LP fixation. In this retrospective study, we aimed to compare the radiographic and clinical outcomes of IN and LP fixation.

Methods

Eighty-five patients (120 feet) underwent the modified Lapidus procedure between 2020 and 2023
