MagnetOs Easypack Putty bone graft coming out of a syringe

Moving the needle in spinal fusion has never been easier

Speed and efficiency are essential in the operating room, which is why we created MagnetOsTM Easypack Putty to be ready-to-use, easy to mold, and designed to stay put. 

It delivers all the benefits of our established MagnetOs family thanks to our unique NeedleGripTM surface technology – which grows bone even in soft tissue* without added cells or growth factors.1-3†‡

Simply dispense MagnetOs Easypack Putty into your hand using the accompanying syringe, mold the product into the shape you need, and it’s ready to be implanted – in any intervertebral disc space or posterolateral spine level.4,§

MagnetOs Easypack Putty meets your perioperative needs, leading to one thing: a more predictable fusion.†¶1,2,5

Ready-to-use 

MagnetOs Easypack Putty comes ready-to-use in an open-ended syringe for instant application into the palm of your hand. No further preparation is needed – thus saving you (and your team) precious minutes in the operating room. 

Easy to mold 

Because of its unique thermo-sensitive polymer binder, MagnetOs Easypack Putty is easy to mold. This allows you to follow the contours of bony defects and fill those that are irregular in shape or size.  

Designed to stay put 

You don’t need to compromise on efficacy for the sake of perioperative performance. MagnetOs Easypack Putty has been formulated to resist irrigation during surgery and minimize post-operative graft migration.6 This is a putty that stays put and can be used as an extender to autograft in the posterolateral spine and intervertebral disc space.§

Clinical Storyboard

MagnetOs Easypack Putty in a 1-level TLIF and PLF with severe foraminal stenosis

Dr. Kathryn McCarthy is a fellowship-trained orthopedic surgeon at Norton Leatherman Spine Center in Louisville, Kentucky. She has 12 years of practice, focusing on adult degenerative pathology and deformity cases throughout the spine.

In the interactive Clinical Storyboard below, one of Dr. McCarthy’s patients is followed before and after a fusion using MagnetOs Easypack Putty at 6 weeks, 12 weeks and 6 months.

Demographics

  • 45-year-old female
  • BMI: 23.9
  • Past medical history: previous C5-6 fusion

Preoperative Exam

Clinical Observations:

  • ODI: 37
  • VAS: back 7, leg 9
  • Chronic back pain
  • Right leg paresthesias and pain

Physical Exam:

  • Right foot dorsiflexion weakness
  • Decreased sensory dermatomal patterns at L5 and S1

Preoperative X-rays and MRI

Preoperative X-rays and MRI

Sagittal plane reveals significant disc space collapse at L5-S1 with discogenic change

Right-sided paracentral disc protrusion with foraminal stenosis is evident

Proceeded with posterior spinal fusion with wide right sided and foraminal decompression with interbody graft replacement from the right side

Posterior aspect of the disc space was packed with MagnetOs Easypack Putty and local autograft following cage placement

Procedure

  • L5-S1 transforaminal lumbar interbody fusion with posterolateral fusion
  • Used 10cc MagnetOs Easypack Putty and autograft along spinal fixation system and within 3D-printed titanium cage4

6 Week X-rays

6 Week X-rays

Well-maintained overall alignment of lumbar spine with no evidence of screw loosening

MagnetOs Easypack Putty evident in the gutters

Improved disc space height

Full rotation of the cage was noted to be difficult but was appropriately placed to maintain lordosis

12 Week X-rays

12 Week X-rays

AP and lateral X-rays show evolution of graft material – consolidation of graft, no loss of overall alignment or fixation

6 Month X-rays

6 Month X-rays

Evidence of mature bone, continuation of healing and further consolidation of graft material in posterolateral gutters and posterior and within the interbody cage

6 Month Postoperative Exam

  • ODI: 42*
  • VAS: back 2, leg 1
  • During this timeline, patient underwent C5-6 revision for adjacent disease, performed ACDF of C4-5 and plated C4-6.
  • *ODI increase unlikely due to TLIF/PLF as reflected as VAS improved

‡ MagnetOs is not cleared by the FDA or TGA as an osteoinductive bone graft.
§ When used in intervertebral body fusion procedures, MagnetOs must be used with an intervertebral body fusion device cleared by FDA for use with a bone void filler.
MagnetOs has been proven to generate more predictable fusions than two commercially available alternatives in an ovine model of posterolateral fusion.
