Zimmer Spine Instinct™ Java® System - pedicle screw system

Product Description

Zimmer Spine’s Instinct Java System is a pedicle screw system designed to provide you with a versatile solution to treat multiple pathologies in a proven design. Screws feature asymmetrical and cancellous threads, improving cortical and cancellous bone fixation and resistance to screw pull-out. The raised dimples and recesses of the screw heads lock the screws securely to the instrumentation and provide numerous options for reduction. In addition, the optimized blocker design limits crossthreading and head splay. The sound design of the Instinct Java System provides you with the tools you need to treat your patients effectively.


Enhanced Fixation

  • Asymmetrical and cancellous screw threads are designed to improve cortical and cancellous bone fixation and resistance to screw pull-out

Reduced Profile

  • The Instinct Java System features low profile screws, minimizing the risk of facet impingement and soft tissue irritation

Optimal Blocker Design

  • Reduces the risk of cross-threading and head splay

Versatile Instrumentation

  • With a 20mm reduction capacity, the Alligator Persuader can address up to Grade 2 spondylolisthesis

Intraoperative Efficiency

  • Aggressive self-tapping cutting flutes facilitate screw insertion
  • Raised dimples and recesses improve connectivity at the screw/instrument interface

Seamless Compatibility

  • The Instinct Java System is designed to be compatible with other Zimmer Spine systems to facilitate complex procedures


Instinct Spinal Fixation Systems are designed for posterior spinal fixation procedures.

Instinct Spinal Fixation Systems are indicated for the temporary correction and stabilization of a portion of the vertebral column from the thoracic vertebrae to the sacrum until fusion takes place usually in a 6 to 12 months’ period.

When fusion is achieved the Instinct Spinal Fixation Systems should be removed taking into account the risk/benefit for the patient.

Instinct Spinal Fixation Systems are indicated to achieve fusion in the thoracic and lumbar spine for documented degenerative diseases of the thoracic and lumbar spine, disk herniation, spondylolisthesis, fractures, spinal stenosis, spinal deformities such as scoliosis, kyphosis, lordosis, tumor, pseudarthrosis or revision of failed fusion attempts.

The surgeon should take into account the normal capacity of the Instinct™ Spinal Fixation Systems depending on his surgical strategy for a given patient in accordance with the state of the art.


Contraindications may be absolute or relative. Circumstances below may reduce the chances of a successful outcome:

  • Any abnormality that affects the normal process of bone remodelling including, but not limited to, severe osteoporosis involving the spine, excessive bone absorption, osteopenia, primary or metastatic tumors involving the spine, active infection at the site or certain metabolic disorders affecting osteogenesis.
  • Insufficient quantity or quality of bone that might inhibit rigid device fixation.
  • Previous history of infection.
  • Excessive local inflammation.
  • Open wounds.
  • Any neuromuscular deficit that places an unusually heavy load on the device during the healing period.
  • Obesity contributes to spinal loading, which may be excessive enough for failure of the fixation of the device or to failure of the device itself.
  • Patients having inadequate tissue coverage of the operative site.
  • Pregnancy.
  • A condition of senility, mental illness or substance abuse. These conditions, among others, may cause the patient to ignore certain necessary limitations and precautions in the use of the implant, leading to failure or other complications.
  • Foreign body sensitivity. When material sensitivity is suspected, appropriate tests should be made prior to material selection or implantation.
  • Other medical or surgical conditions that would preclude the potential benefits of spinal implant surgery, such as the presence of tumor, congenital abnormalities, elevation of white blood cell count (WBC), or marked left shift in the WBC differential count.
These contraindications can be relative or absolute and must be taken into account by the physician when making his decision. The above list is not exhaustive.
