[Lumbosacral facet joint stabilization: Mc Bride technique]

Area of Science:

• Spine surgery
• Degenerative spine disease
• Lumbar stenosis

Context:

• Retrospective study of 340 patients (May 1996-May 2003) with degenerative unstable lumbar stenosis.
• Patients had chronic lumbar pain and segmental instability unresponsive to conservative treatment.
• Mean age at surgery was 47 years, with 3-8 years of follow-up.

Purpose:

• Evaluate the clinical outcomes of the McBride technique for degenerative unstable lumbar stenosis.
• Assess the efficacy of interlaminar distraction combined with arthrodesis.

Summary:

• The McBride technique, utilizing interlaminar distraction, achieved very good results in 33.5% and good results in 59.7% of patients.
• This method simultaneously addresses lumbar stenosis and segmental instability.
• It decompresses neural elements, maintains extension, reduces facet subluxation, and facilitates fusion.

Impact:

• Demonstrates high success rates for the McBride technique in managing complex lumbar conditions.
• Highlights the technique's ability to provide immediate stabilization and promote long-term fusion.
• Offers a viable surgical option for patients with chronic lumbar pain and instability.
