A bone implant assembly comprising: an implant including: a spacer configured to be inserted into an intervertebral space, and a fixation plate configured to attach to the spacer, the fixation plate defining at least one aperture extending therethrough, a bone anchor configured for insertion into the aperture so as to extend through the at least one aperture and into a bone (V6, V7), thereby affixing the implant to the bone, the bone anchor including: a proximal end, a distal end opposite the proximal end, and an intermediate portion extending therebetween, the distal end defining a tip having a sharpened tip point that is configured as a trocar tip, the sharpened tip point being configured to cut into the bone (V6, V7), the proximal end defining a head, the bone anchor further including a shaft that is elongate along a central longitudinal axis, the shaft extending proximally from the tip to the head, and at least a portion of the shaft being unthreaded from the tip and along a portion of the intermediate portion toward the proximal end, wherein the shaft defines an external thread that extends between the head and the unthreaded portion, the bone anchor configured to extend through the at least one aperture and into the bone (V6, V7) so as to fix the implant to the bone, such that the external thread contacts the bone (V6, V7). an implant including: a spacer configured to be inserted into an intervertebral space, and a fixation plate configured to attach to the spacer, the fixation plate defining at least one aperture extending therethrough, a bone anchor configured for insertion into the aperture so as to extend through the at least one aperture and into a bone (V6, V7), thereby affixing the implant to the bone, the bone anchor including: a proximal end, a distal end opposite the proximal end, and an intermediate portion extending therebetween, the distal end defining a tip having a sharpened tip point that is configured as a trocar tip, the sharpened tip point being configured to cut into the bone (V6, V7), the proximal end defining a head, the bone anchor further including a shaft that is elongate along a central longitudinal axis, the shaft extending proximally from the tip to the head, and at least a portion of the shaft being unthreaded from the tip and along a portion of the intermediate portion toward the proximal end, wherein the shaft defines an external thread that extends between the head and the unthreaded portion, the bone anchor configured to extend through the at least one aperture and into the bone (V6, V7) so as to fix the implant to the bone, such that the external thread contacts the bone (V6, V7). a spacer configured to be inserted into an intervertebral space, and a fixation plate configured to attach to the spacer, the fixation plate defining at least one aperture extending therethrough, a bone anchor configured for insertion into the aperture so as to extend through the at least one aperture and into a bone (V6, V7), thereby affixing the implant to the bone, the bone anchor including: a proximal end, a distal end opposite the proximal end, and an intermediate portion extending therebetween, the distal end defining a tip having a sharpened tip point that is configured as a trocar tip, the sharpened tip point being configured to cut into the bone (V6, V7), the proximal end defining a head, the bone anchor further including a shaft that is elongate along a central longitudinal axis, the shaft extending proximally from the tip to the head, and at least a portion of the shaft being unthreaded from the tip and along a portion of the intermediate portion toward the proximal end, a proximal end, a distal end opposite the proximal end, and an intermediate portion extending therebetween, the distal end defining a tip having a sharpened tip point that is configured as a trocar tip, the sharpened tip point being configured to cut into the bone (V6, V7), the proximal end defining a head, the bone anchor further including a shaft that is elongate along a central longitudinal axis, the shaft extending proximally from the tip to the head, and at least a portion of the shaft being unthreaded from the tip and along a portion of the intermediate portion toward the proximal end, wherein the shaft defines an external thread that extends between the head and the unthreaded portion, the bone anchor configured to extend through the at least one aperture and into the bone (V6, V7) so as to fix the implant to the bone, such that the external thread contacts the bone (V6, V7).
