Item Open Access Complications associated with surgical treatment of traumatic spinal fractures: a review of the scoliosis research society morbidity and mortality database.(World neurosurgery, 2014-05) Williams, Brian J; Smith, Justin S; Saulle, Dwight; Ames, Christopher P; Lenke, Lawrence G; Broadstone, Paul A; Vaccaro, Alexander R; Polly, David W; Shaffrey, Christopher IObjective
Traumatic spinal fracture is a common indication for surgery, with an associated high incidence of perioperative complications. The literature provides a wide range in the incidence of complications. We seek to assess the perioperative morbidity and mortality of surgery for traumatic spinal fractures and to identify predictors of their occurrence.Methods
We performed a retrospective analysis of all traumatic spinal fracture cases submitted by members of the Scoliosis Research Society from 2004 to 2007.Results
A total of 108,478 cases were submitted from 2004 through 2007, with 6,706 (6.2%) performed for treatment of traumatic fracture. Twenty-two percent of patients had preoperative neurological deficits. Intraoperative neuromonitoring was used in 58% of cases. The overall incidence of complications was 6.9%. The perioperative mortality was 0.5%. There were 59 (0.9%) new postoperative neurological deficits. Multivariate analysis demonstrated preoperative neurological deficit (P = .001; odds ratio [OR] 1.449, 95% confidence interval [CI] [1.156 to 1.817]) and fusion (P =.001; OR 1.12, 95% CI [1.072 to 1.168]) as predictors of complications and use of intraoperative neuromonitoring (P = .016; OR 1.949, 95% CI [1.13 to 3.361]), and preoperative neurological deficit (P < .001; OR 2.964, 95% CI [1.667 to 5.271]) as predictors of new postoperative neurological deficits (P < .001).Conclusions
Overall, surgery for the treatment of spinal fractures was performed with relatively low incidences of perioperative complications (6.9%) and mortality (0.5%). These data may prove useful for patient counseling and ongoing efforts to improve the safety of operative care for patients with spinal fracture.Item Open Access Faced joint locking.(Journal of neurosurgery.

Pediatrics, 2011-01) Fu, Kai-Ming G; Smith, Justin S; Polly, David W; Ames, Christopher P; Berven, Sigurd H; Perra, Joseph H; Glassman, Steven D; McCarthy, Richard E; Knapp, D Raymond; Shaffrey, Christopher I; Scoliosis Research Society Morbidity and Mortality CommitteeObject
Currently, few studies regarding morbidity and mortality associated with operative treatment of spinal disorders in children are available to guide the surgeon. This study provides more detailed morbidity and mortality data with an analysis of 23,918 pediatric cases reported in the multicenter, multisurgeon Scoliosis Research Society morbidity and mortality database.Methods
The Scoliosis Research Society morbidity and mortality database was queried for the years from 2004 to 2007. The inclusion criterion was age 18 years or younger. Cases were categorized by operation type and diagnosis. Details on the surgical approach, use of neurophysiological monitoring, and type of instrumentation were recorded. Major perioperative complications and deaths were evaluated. Statistical analysis was performed with chi-square testing, with a p value < 0.05 considered significant.Results
A total of 23,918 patients were included. The mean age was 13 ± 3.6 years (± SD). Spinal pathology included the following: scoliosis (in 19,642 patients), kyphosis (in 1455), spondylolisthesis (in 748), trauma (in 478), and other (in 1595 patients). The overall complication rate was 8.5%. Major complications included wound infections (2.7%), new neurological deficits (1.4%), implant-related complications (1.6%), and hematomas (0.4%). The most common medical complications were respiratory related (0.9%). Morbidity rates differed based on pathology, with patients undergoing treatment for kyphosis and spondylolisthesis having higher overall rates of morbidity (14.7% and 9.6%, respectively). Patients undergoing revision procedures (2034) or corrective osteotomies (2787) were more likely to suffer a complication or new neurological deficit. The majority of these deficits improved at least partially. Thirty-one deaths were reported for an overall rate of 1.3 per 1000. Respiratory complications were the most common cause of mortality (13 cases). Twenty-six of the deaths occurred in children undergoing scoliosis correction.Conclusions
Spinal surgery in children is associated with a range of complications depending on the type of operation. Mortality rates for all indications and operations were low. Patients undergoing more aggressive corrective procedures for deformity are more likely to suffer complications and new neurological deficits.Item Open Access The AOSpine North America Geriatric Odontoid Fracture Mortality Study: a retrospective review of mortality outcomes for operative versus nonoperative treatment of 322 patients with long-term follow-up.(Spine, 2013-06) Chapman, Jens; Smith, Justin S; Kopjar, Branko; Vaccaro, Alexander R; Arnold, Paul; Shaffrey, Christopher I; Fehlings, Michael GSTUDY DESIGN: Retrospective, multicenter cohort study. OBJECTIVE: Assess for differences in short- and long-term mortality between operative and nonoperative treatment for elderly patients with type II odontoid fractures. SUMMARY OF BACKGROUND DATA: There is controversy regarding whether operative or nonoperative management is the best treatment for elderly patients with type II odontoid fractures. METHODS: This is a retrospective study of consecutive patients aged 65 years or older with type II odontoid fracture from 3 level I trauma centers from 2003-2009. Demographics, comorbidities, and treatment were abstracted from medical records. Mortality outcomes were obtained from medical records and a public database. Hazard ratios (HRs) and 95% confidence intervals (CI) were calculated. RESULTS: A total of 322 patients were included (mean age, 81.8 yr; range, 65.0-101.5 yr). Compared with patients treated nonoperatively (n = 157), patients treated operatively (n = 165) were slightly younger (80.4 vs. 83.2 yr, P = 0.0014), had a longer hospital (15.0 vs. 7.4 d, P < 0.001) and intensive care unit (1.5 vs. 1.1 d, P = 0.008) stay, and were more likely to receive a feeding tube (18% vs. 5%, P = 0.0003). Operative and nonoperative treatment groups had similar sex distribution (P = 0.94) and Charlson comorbidity index (P = 0.11). Within 30 days of presentation, 14% of patients died, and at maximal follow-up (average = 2.05 yr; range = 0 d-7.02 yr), 44% had died. On multivariate analysis, nonoperative treatment was associated with higher 30-day mortality (HR = 3.00, 95% CI = 1.51-5.94, P = 0.0017), after adjusting for age (HR = 1.10, 95% CI = 1.05-1.14; P < 0.0001), male sex (P = 0.69), and Charlson comorbidity index (P = 0.16). At maximal follow-up, there was a trend toward higher mortality associated with nonoperative treatment (HR = 1.35, 95% CI = 0.97-1.89, P = 0.079), after adjusting for age (HR = 1.07, 95% CI = 1.05-1.10; P < 0.0001), male sex (HR = 1.55, 95% CI = 1.10-2.16; P = 0.012), and Charlson comorbidity index (HR = 1.28, 95% CI = 1.16-1.40; P < 0.0001). CONCLUSION: Surgical treatment of type II odontoid fracture in this elderly population did not negatively impact survival, even after adjusting for age, sex, and comorbidities. The data suggest a significant 30-day survival advantage and a trend toward improved longer-term survival for operatively treated over nonoperatively treated patients. LEVEL OF EVIDENCE: 4.
