Spinopelvic fixation provides an important anchor for long fusions in spinal deformity surgery, and it is also used in the treatment of other spine pathologies. Iliac screws are known to sometimes require reoperation due to pain resulting from hardware prominence and skin injury. S-2 alar/iliac (S2AI) screws do not often require removal, but they may provide inadequate fixation in select cases. In this paper the authors describe a technique for S-1 alar/iliac screws that may be used independently or as a supplement to S2AI screws. A preliminary biomechanical analysis and 2 clinical case examples are also provided.

Spinal epidural abscesses (SEAs) can be difficult to diagnose and may result in neurological compromise or even death. Delays in diagnosis or treatment may worsen the prognosis. While SEA presents a high risk for litigation, little is known about the medicolegal ramifications of this condition. An enhanced understanding of potential legal implications is important for practicing spine surgeons, emergency medicine physicians, and internists.
The VerdictSearch database, a large legal-claims database, was queried for “epidural abscess”–related legal cases. Demographic and clinical data were examined for all claims; any irrelevant cases or cases with incomplete information were excluded. The effects of age of the plaintiff, sex of the plaintiff, presence of a known infection, resulting paraplegia or quadriplegia, delay in diagnosis, and delay in treatment on the proportion of plaintiff rulings and size of payments were assessed.
In total, 56 cases met the inclusion criteria. Of the 56 cases, 17 (30.4%) were settled, 22 (39.3%) resulted in a defendant ruling, and 17 (30.4%) resulted in a plaintiff ruling. The mean award for plaintiff rulings was $5,277,468 ± $6,348,462 (range $185,000–$19,792,000), which was significantly larger than the mean award for cases that were settled out of court, $1,914,265 ± $1,313,322 (range $100,000–$4,500,000) (p < 0.05). The mean age of the plaintiffs was 47.0 ± 14.4 years; 23 (41.1%) of the plaintiffs were female and 33 (58.9%) were male. The proportion of plaintiff verdicts and size of monetary awards were not affected by age or sex (p > 0.49). The presence of a previously known infection was also not associated with the proportion of plaintiff verdicts or indemnity payments (p > 0.29). In contrast, juries were more likely to rule in favor of plaintiffs who became paraplegic or quadriplegic (p = 0.03) compared with plaintiffs who suffered pain or isolated weakness. Monetary awards for paraplegic or quadriplegic patients were also significantly higher (p = 0.003). Plaintiffs were more likely to win if there was a delay in diagnosis (p = 0.04) or delay in treatment (p = 0.006), although there was no difference in monetary awards (p > 0.57). Internists were the most commonly sued physician (named in 13 suits [23.2%]), followed by emergency medicine physicians (named in 8 [14.3%]), and orthopedic surgeons (named in 3 [5.4%]).
This investigation is the largest examination of legal claims due to spinal epidural abscess to date. The proportion of plaintiff verdicts was significantly higher in cases in which the patient became paraplegic or quadriplegic and in cases in which there was delay in diagnosis or treatment. Additionally, paralysis is linked to large sums awarded to the plaintiff. Nonsurgeon physicians, who are often responsible for initial diagnosis, were more likely to be sued than were surgeons.

Authors of this study analyzed hospital readmissions following laminectomy and developed predictive models to identify readmitted patients with an accuracy >95% when using all variables and >79% when using only predischarge variables. A model capable of predicting 40% of readmitted patients was created using only the variables known predischarge. This investigation is important in its provision of data that will assist the development of predictive models for readmission as well as interventions to prevent readmission in high-risk patients.

Sarcopenia, the muscle atrophy associated with aging and disease progression, accounts for nearly $18.5 billion in health care expenditures annually. Given the high prevalence of sarcopenia in patients undergoing orthopedic surgery, the goal of this study was to assess the impact of sarcopenia on inpatient costs following thoracolumbar spine surgery.
Patients older than 55 years undergoing thoracolumbar spine surgery from 2003 to 2015 were retrospectively analyzed. Sarcopenia was measured using total psoas area at the L-4 vertebra on perioperative CT scans. Hospital billing data were used to compare inpatient costs, transfusion rate, and rate of advanced imaging utilization.
Of the 50 patients assessed, 16 were sarcopenic. Mean total hospital costs were 1.75-fold greater for sarcopenic patients compared with nonsarcopenic patients ($53,128 vs $30,292, p = 0.04). Sarcopenic patients were 2.1 times as likely to require a blood transfusion (43.8% vs 20.6%, p = 0.04). Sarcopenic patients had a 2.6-fold greater usage of advanced imaging (68.8% vs 26.5%, p = 0.002) with associated higher diagnostic imaging costs ($2452 vs $801, p = 0.01). Sarcopenic patients also had greater pharmacy, laboratory, respiratory care, and emergency department costs.
This study is the first to show that sarcopenia is associated with higher postoperative costs and rates of blood transfusion following thoracolumbar spine surgery. Measuring the psoas area may represent a strategy for predicting perioperative costs in spine surgery patients.

Adverse events related to spine surgery sometimes lead to litigation. Few studies have evaluated the association between spine surgical complications and medical malpractice proceedings, outcomes, and awards. The aim of this study was to identify the most frequent causes of alleged malpractice in spine surgery and to gain insight into patient demographic and clinical characteristics associated with medical negligence litigation.
A search for “spine surgery” spanning February 1988 to May 2015 was conducted utilizing the medicolegal research service VerdictSearch (ALM Media Properties, LLC). Demographic data for the plaintiff and defendant in addition to clinical data for the procedure and legal outcomes were examined. Spinal cord injury, anoxic/hypoxic brain injury, and death were classified as catastrophic complications; all other complications were classified as noncatastrophic. Both chi-square and t-tests were used to evaluate the effect of these variables on case outcomes and awards granted.
A total of 569 legal cases were examined; 335 cases were excluded due to irrelevance or insufficient information. Of the 234 cases included in this investigation, 54.2% (127 cases) resulted in a defendant ruling, 26.1% (61) in a plaintiff ruling, and 19.6% (46) in a settlement. The awards granted for plaintiff rulings ranged from $134,000 to $38,323,196 (mean $4,045,205 ± $6,804,647). Awards for settlements ranged from $125,000 to $9,000,000 (mean $1,930,278 ± $2,113,593), which was significantly less than plaintiff rulings (p = 0.022). Compared with cases without a delay in diagnosis of the complication, the cases with a diagnostic delay were more likely to result in a plaintiff verdict or settlement (42.9% vs 72.7%, p = 0.007) than a defense verdict, and were more likely to settle out of court (17.5% vs 40.9%, p = 0.008). Similarly, compared with cases without a delay in treatment of the complication, those with a therapeutic delay were more likely to result in a plaintiff verdict or settlement (43.7% vs 68.4%, p = 0.03) than a defense verdict, and were more likely to settle out of court (18.1% vs 36.8%, p = 0.04). Overall, 28% of cases (66/234) involved catastrophic complications. Physicians were more likely to lose cases (plaintiff verdict or settlement) with catastrophic complications (66.7% vs 37.5%, p < 0.001). In cases with a plaintiff ruling, catastrophic complications resulted in significantly larger mean awards than noncatastrophic complications ($6.1M vs $2.9M, p = 0.04). The medical specialty of the provider and the age or sex of the patient were not associated with the case outcome or award granted (p > 0.05). The average time to a decision for defendant verdicts was 5.1 years; for plaintiff rulings, 5.0 years; and for settlements, 3.4 years.
Delays in the diagnosis and the treatment of a surgical complication predict legal case outcomes favoring the plaintiff. Catastrophic complications are linked to large sums awarded to the plaintiff and are predictive of rulings against the physician. For physician defendants, the costs of settlements are significantly less than those of losing in court. Although this study provides potentially valuable data from a large series of postoperative litigation cases, it may not provide a true representation of all jurisdictions, each of which has variable malpractice laws and medicolegal environments.
