FORZA XP Expandable Spacer System

The FORZA® XP Expandable Spacer System offers titanium alloy expandable interbodies for Posterior Lumbar Interbody Fusion (PLIF) and Transforaminal Lumbar Interbody Fusion (TLIF) procedures. After insertion into the disc space, the interbodies can be expanded to fit the patient anatomy. Unlike many competitive expandables that trade off graft space in order to stay within the limits of their expansion design, FORZA XP has a large graft window and affords the user the ability to pack the graft window in situ while retaining its expansion capability.

Product Highlights

  • Minimized insertion height helps to reduce nerve root retraction and minimize impaction force
  • Controlled continuous expansion† – not incremental like some competitors
  • In situ distraction allows disc height restoration and an optimized fit
  • Automatic locking – height stability without an extra locking step
  • Anatomic profile – optimal fit within vertebral endplates*
  • Inserter stays in place for insertion, expansion, and graft material post packing – fewer passes by the nerve root with instrumentation
  • Placement of bone graft after expansion – able to fill the graft window space with implant in situ

*Note: 6.5mm implants do not have anatomic endplates

†Controlled expansion up to 3mm

Indications

The FORZA XP Expandable Spacer System is indicated for spinal fusion procedures in skeletally mature patients with degenerative disc disease (DDD) at one or two contiguous levels in the lumbar spine (L2-S1). DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by patient history and radiographic studies. DDD patients may also have up to Grade 1 spondylolisthesis at the involved levels.  These patients may have had a previous non-fusion surgery at the involved level(s).

The FORZA XP Expandable Spacer System is intended for use with autograft and/or allograft comprised of cancellous and/or corticocancellous bone graft; and supplemental fixation system (i.e. Firebird® Spinal Fixation System).

Patients must have undergone a regimen of at least six months of non-operative treatment prior to being treated with the FORZA XP Expandable Spacer System.​

Contraindications

The FORZA XP Expandable Spacer System, as with other orthopedic implants, is contraindicated for use in patients with:​

  • Active infections in which the use of an implant could preclude adequate and appropriate treatment of the infection.
  • Rapidly progressive joint disease or bone absorption syndromes such as Paget’s disease, osteopenia, osteoporosis, or osteomyelitis which may prevent adequate fixation.
  • Conditions that may place excessive stresses on bone and implants, such as severe obesity, pregnancy or degenerative diseases. The decision to use this system in such conditions must be made by the physician taking into account the risks versus the benefits to the patient.
  • Prior fusion at the level to be treated.
  • Any circumstances not listed under the Indications for Use section.
