Publication number: 20230049680Abstract: An anterior lumbar interbody fusion device comprising a superior component, an inferior component, and a locking mechanism. The superior component bottom side and the inferior component top side oppose each other when these are received in the intervertebral space whereby their external sides abut against the respective vertebra, thereby coupling force between the latter. The components inter-engage with each other whereby they are constrained to move in an anterior-posterior direction relative to each other and resistance is presented to movement relative to each other in each of a direction of separation and a direction orthogonal to the anterior-posterior direction and to the direction of separation.Type: ApplicationFiled: January 21, 2021Publication date: February 16, 2023Inventors: Jonathan ARCOS, Christopher REAH, Nicholas SANDHAM, David POWELL
