• OBJECTIVES
    • The purpose of this cadaveric study was to evaluate whether there is any damage to the gluteus medius tendon when reaming through a modified medial trochanteric portal for antegrade intramedullary femoral nailing.
  • METHODS
    • Ten cadaver hips were used in this study. A guidewire was placed in the modified medial trochanteric portal using the assistance of C-arm fluoroscopy and a 14-mm reamer was advanced over the wire. After the reaming was complete, each hip was dissected and the gluteus medius muscle and tendon were inspected to evaluate the amount of intrasubstance and medial tendon damage.
  • RESULTS
    • Precise localization of the modified medial trochanteric portal was achieved in 9 of 10 cadaver hips. Of those nine hips, the use of the modified medial trochanteric portal did not result in any visible damage to the tendinous insertion of the gluteus medius or the medial aspect of the tendon in any of the specimens.
  • CONCLUSIONS
    • There is no damage to the gluteus medius tendon with the use of the modified medial trochanteric portal. Although the clinical implications of this finding are not known with certainty, the use of the modified medial trochanteric entry portal for antegrade femoral nailing could possibly result in less postoperative morbidity because it does not damage the gluteus medius tendon as compared to the traditional more lateral trochanteric portal.
