Pedicle Subtraction Osteotomy Better With Two Surgeons
(HealthDay News) – Using a two-surgeon strategy for pedicle subtraction osteotomies is associated with better outcomes, according to a study published in the January issue of Spine Deformity.
Christopher P. Ames, MD, from the University of California in San Francisco, and colleagues assessed all 78 pedicle subtraction osteotomy cases (2005–2010) and compared perioperative morbidity based on the presence of a one (42 cases) or two surgeons (36 cases). Subset analysis excluded cases before 2007 and patients with staged anterior and posterior procedures.
The researchers found that the two groups differed significantly with respect to age (57.6 vs. 64.3 years in the single- versus two-surgeon groups), but were similar in terms of the mean number of posterior levels fused, levels decompressed, revision rates, and correction of radiographic parameters. The mean estimated blood loss was significantly higher with a single surgeon versus two surgeons (109 vs. 35%), as was estimated blood loss (5,278 mL vs. 2,003 mL). The average surgical time was significantly longer for single versus two surgeons (7.6 vs. 5.0 hours). There was at least one major complication within 30 days in 45% of the single-surgeon group compared with 25% of the two-surgeon group. There were also higher rates of unplanned surgery within 30 days in the single-surgeon group (19%) vs. the two-surgeon group (8%).
"The use of two surgeons at an experienced spine deformity center decreases the operative time and estimated blood loss, and may be a key factor in witnessed decreased major complication prevalence," the authors write.
