Editorial Commentary: Magnetic Resonance Imaging Analysis of Labral Volume Can Indicate the Need for Labral Reconstruction and Subsequently Predict the Success of the Procedure.

Abstract

Along with irreparable labrum from failed prior surgery, diminutive or calcified labrum in cases of primary surgery have become an indication for labral reconstruction of the hip. Radiologists can reliably and accurately measure the labral width or height and volume on magnetic resonance imaging (MRI). For preoperative purposes, an MRI that confirms a diminutive labrum can lead the surgeon to indicate primary labral reconstruction as the native labrum may not be providing an adequate suction seal to the femoral head. For postoperative purposes, MRI measurements of the volume of the labral graft can provide the surgeon and patient with important information about the healing progress and ultimate success of the reconstruction. Future routine postoperative MRI measurements of labral volume will help the hip arthroscopist determine the ideal volume of the labral reconstruction graft.
