Half Dome
Posterior Lumbar Interbody Spacer System
The Half Dome Posterior Lumbar Interbody Spacer System is a comprehensive system that provides a complete range of anatomic, self-distracting spacers and instrumentation to support all posterior lumbar approaches. The intuitive design of the system provides the versatility to accommodate a wide array of anatomical challenges to ensure an efficient, streamlined procedural sequence.

Implants Overview
-
All Half Dome Posterior Lumbar Interbody Spacers are:
- Available in either Acid-etched Ti, HA PEEK, or PEEK
- A bulleted nose that allows for self-distraction of the intervertebral space during insertion while conserving critical structural anatomy
- Large central aperture to pack bone graft to provide a greater opportunity for fusion
- Lateral windows to provide additional graft vascularization
-
-

-
Half Dome OTLIF
- Designed for either an Oblique Transforaminal Lumbar Interbody Fusion (OTLIF) or Posterior Lumbar Interbody Fusion (PLIF) approach
- Heights: 7-15mm in 1mm increments
- Lengths: 22, 24, 26, 28, 30, or 32mm
- Width: 9mm
- Biconvex

Surface Options
-
-
-
- Acid-etched endplates to resist migration postoperatively
- Acid-etched surface enhances and increases the efficiency of bone growth
- HA is fully integrated, not coated, making it available on all surfaces of the spacer to provide an osteoconductive surface for bone ingrowth
- Unidirectional serrated teeth to resist migration postoperatively
- Radiographic markers provide fluoroscopic visualization of the exact orientation of the spacer during implantation
