TRANSPEDICULAR SCREW FIXATION IN DEGENERATIVE LUMBOSACRAL SPINE DISEASE SURGICAL OUTCOME

Area of Science:

• Orthopedics
• Neurosurgery
• Spinal Surgery

Background:

• Degenerative lumbar spine disease causes chronic pain and neurological deficits.
• Pedicle screw fixation is a common surgical intervention for spinal instability.

Purpose of the Study:

• To prospectively evaluate the surgical outcomes of pedicle screw fixation in patients with degenerative lumbar spine disease.
• To assess the efficacy and complication rates of pedicle screw usage in this patient cohort.

Main Methods:

• A prospective study of 55 consecutive patients (ages 25-60) with degenerative lumbar spine disease.
• Patients underwent posterior surgical stabilization with pedicle screw fixation and fusion.
• Preoperative and postoperative X-rays were used to evaluate screw placement and fusion.

Main Results:

• All patients experienced significant pain reduction and improvement in paresthesia.
• 10 patients with lower limb neurological deficits showed improvement.
• Complications included 5 re-operations (displacement, broken/loose screws), 3 dural tears, and 1 deep vein thrombosis; no vascular injury or infection was observed.

Conclusions:

• Pedicle screw fixation is a safe and effective method for treating degenerative lumbar spine disease, facilitating bone fusion and improving patient symptoms.
• While technically demanding, pedicle screw placement, when performed with anatomical knowledge, is associated with a low complication rate.
• This technique is indicated for spinal instability, whether pre-existing or iatrogenic.
