Sagittal plane considerations during long cephalomedullary nailing: Optimal distal positioning and the role of intraoperative nail bending
Journal of Orthopaedic Trauma Oct 29, 2019
Georgiadis GM, et al. - Researchers retrospectively reviewed a large population of long cephalomedullary nails with special attention to distal implant position in the sagittal plane and evaluate the ability to bypass anterior cortical contact (ACC) by bending the distal tip of the nail intraoperatively. A total of 215 individuals who underwent long cephalomedullary nailing for peritrochanteric hip fractures between 2007 and 2017 were analyzed. ACC of the distal portion of the nail in the sagittal plane was a general finding. Its frequency significantly reduced following intraoperative bending of long cephalomedullary nails was included in practice in individuals where sagittal plane impingement was identified. If the final nail position was proximal to the level of the patella, ACC was more common. Hence, during the insertion of a long cephalomedullary nail, meticulous attention should be given to sagittal plane anatomy and distal ACC. To prevent anterior impingement or perforation, one approach could be intraoperative bending of the distal end of the nail.
