PURPOSE: To compare peri-operative complication rates in ≥ 85-year-old patients who underwent decompression surgery with or without instrumented fusion for degenerative disorders.
METHODS: This study involved 907 patients who underwent lumbar spine surgery for degenerative disorders between January 2006 and June 2012. Of these, 33 patients (3.6% of the entire population) were over 85 years of age (85-94 years). Decompression-alone and instrumentation groups were compared in terms of comorbidities, American Society of Anesthesiologists (ASA)-physical status (PS) class, peri-operative complications, and Japanese Orthopedic Association (JOA) scores.
RESULTS: Thirty-three ≥ 85-year-old patients underwent surgery. All were ASA-PS class 2 (94%) or 3. The decompression-alone (n = 19) and instrumentation (n = 14) groups did not differ in comorbidity (95 vs. 100%, P = 0.383) or ASA-PS class (P = 0.561). Both exhibited improved JOA scores (decompression-alone: 13.4/29 to 22.7/29; instrumentation: 8.6/29 to 17.9/29; P = 0.9068) and had similar peri-operative complication rates (21.0 vs. 28.5%, P = 0.374).
CONCLUSIONS: Although instrumentation is considered more invasive than decompression, we detected no statistically significant differences in peri-operative complication rates between these two types of surgery in ≥ 85-year-old patients. Surgeons should perform instrumentation even in the patients over 85 years with ASA class 3 or less.
