[Segmental rod wiring of the spinous process]

Area of Science:

• Orthopedic Surgery
• Spinal Surgery
• Biomedical Engineering

Background:

• Traditional spinal instrumentation methods like Luque's and Harrington's have been widely used for scoliosis correction.
• Sublaminar wiring, a component of some techniques, carries risks to spinal canal structures.
• There is a need for safer and equally effective spinal instrumentation techniques.

Purpose of the Study:

• To introduce and evaluate a new technique for segmental spinal instrumentation.
• To compare the efficacy and safety of this new technique against established methods for scoliosis correction.
• To assess the benefits of this technique in patients with spine metastases.

Main Methods:

• A novel segmental spinal instrumentation technique was developed, specifically avoiding sublaminar wiring.
• The technique was applied to twenty patients with scoliosis for correction and stability assessment.
• The method was also utilized in the operative treatment of thirty-two patients with spine metastases.

Main Results:

• The new technique achieved scoliosis correction and provided primary, lasting stability comparable to Luque's original method.
• The technique demonstrated no danger of violating spinal canal structures.
• Results in scoliosis patients were comparable to those reported for Harrington's or Luque's instrumentation.
• Remarkable improvements in quality of life were observed in all patients with spine metastases.

Conclusions:

• The described segmental spinal instrumentation technique offers a safe alternative to existing methods for scoliosis.
• This technique provides effective correction and stability without compromising spinal canal integrity.
• The method shows significant promise for improving the quality of life in patients with spine metastases.
