Posterior Cervical Instruments Kit (cervical vertebra)

Posterior Cervical Instruments Kit (cervical vertebra)

    A polyaxial  screw is used for connecting vertebrae to rods in spinal surgery. It is essentially a screw whose spherical head is enclosed on a housing, which allows the screw a range of motion along several different axes relative to the housing. The ball joint allows the surgeon some flexibility in placing the screws.It has also been hypothesized that polyaxial screws add a safety benefit by failing in the housing screw interface before breaking in the shaft of the bone screw or in the orthopaedic rod. Unlike standard lateral mass plate and screw systems, the new cervical polyaxial screw and rod system easily accommodates severe degenerativecervical spondylosis and curvatures. This instrumentation system allows for polyaxial screw placement with subsequent multiplanar rod contouring and offset attachment.

Spinal fusion, also known as spondylodesis or spondylosyndesis, is a surgical technique used to join two or more vertebrae. Supplementary bone tissue, either from the patient (autograft) or a donor (allograft), is used in conjunction with the body's natural bone growth (osteoblastic) processes to fuse the vertebrae.

Fusing of the spine is used primarily to eliminate the pain caused by abnormal motion of the vertebrae by immobilizing the faulty vertebrae themselves, which is usually caused by degenerative conditions. However, spinal fusion is also the preferred way to treat most spinal deformities, specifically scoliosis and kyphosis.

There are two main types of lumbar spinal fusion, which may be used in conjunction with each other:

Posterolateral fusion places the bone graft between the transverse processes in the back of the spine. These vertebrae are then fixed in place with screws and/or wire through the pedicles of each vertebra attaching to a metal rod on each side of the vertebrae.

Interbody fusion places the bone graft between the vertebra in the area usually occupied by the intervertebral disc. In preparation for the spinal fusion, the disc is removed entirely, for example in ACDF. A device may be placed between the vertebra to maintain spine alignment and disc height. The intervertebral device may be made from either plastic or titanium. The fusion then occurs between the endplates of the vertebrae. Using both types of fusion is known as 360-degree fusion. Fusion rates are higher with interbody fusion. Three types of interbody fusion are:

• Anterior lumbar interbody fusion (ALIF)- the disc is accessed from an anterior abdominal incision
• Posterior lumbar interbody fusion (PLIF) - the disc is accessed from a posterior incision
• Transforaminal lumbar interbody fusion (TLIF) - the disc is accessed from a posterior incision on one side of the spine
• Transpsoas interbody fusion (DLIF or XLIF) - the disc is accessed from an incision through the psoas muscle on one side of the spine
