[Transpedicular lumbar spondylodesis in elderly patients]

Area of Science:

• Orthopedics
• Neurosurgery
• Spinal Surgery

Background:

• Degenerative changes in the lumbar spine affect a significant portion of the aging population.
• Spinal fusion procedures aim to alleviate pain and instability caused by degenerative conditions.
• Evaluating long-term outcomes and predictors of success in lumbar spine fusion is crucial for patient management.

Purpose of the Study:

• To assess the clinical outcomes of CD-spondylodesis for degenerative lumbar spine changes in patients over 50.
• To identify factors influencing the success of lumbar spine fusion.
• To determine if early clinical results predict long-term outcomes.

Main Methods:

• Retrospective analysis of 70 patients over 50 who underwent CD-spondylodesis between 1987 and 1991.
• Follow-up period of 2 years to evaluate clinical outcomes.
• Statistical analysis to identify correlations between preoperative/postoperative factors and clinical results.

Main Results:

• 88.2% of patients showed improvement, with 47.1% achieving good-to-excellent results.
• Factors associated with poorer outcomes included more previous lumbar surgeries, greater preoperative kyphosis, and postoperative motor weakness.
• Early clinical differences noted at 6 months were predictive of the final 2-year outcome.

Conclusions:

• CD-spondylodesis can improve outcomes for degenerative lumbar spine disease, but success is influenced by specific patient and surgical factors.
• Preoperative conditions and early postoperative recovery are critical indicators of long-term success.
• Identifying patients at risk for poorer outcomes can aid in surgical decision-making and patient counseling.
