Use of an intraoperative sodium oxychlorosene-based infection prevention protocol to safely decrease postoperative wound infections after spine surgery.

OBJECTIVE: Postoperative infection remains prevalent after spinal surgical procedures. Institutional protocols for infection prevention have improved rates of infection after spine surgery. However, prior studies have focused on only elective surgical patients. The aim of this study was to determine the efficacy of a multiinstitutional intraoperative sodium oxychlorosene-based infection prevention protocol for decreasing rate of infection after instrumented spinal surgery. METHODS: A retrospective analysis was performed at two tertiary care institutions with level I trauma programs, and patients who underwent posterior instrumented spinal fusion between January 1, 2011, and May 31, 2019, were included. Postoperative deep wound infection rates were captured before and after implementation of a multiinstitutional infection prevention protocol. Possible adverse outcomes related to infection prevention techniques were also examined. In addition, consecutive patients treated from January 1, 2018, to May 31, 2019, were prospectively included in a database to collect preoperative and postoperative spine-specific quality of life measures and to assess the impact of postoperative infection on quality of life. RESULTS: A total of 5047 patients fit the inclusion criteria. Of these, 1043 patients underwent surgery prior to protocol implementation. The infection rate of this cohort (3.5%) decreased significantly after protocol implementation (1.2%, p < 0.001). Postoperative sterile seroma rates did not differ between the preprotocol and postprotocol groups (0.7% vs 0.7%, p = 0.5). In the 1031 patients who underwent surgery between January 2018 and May 2019, the fusion rate was 89.2%. Quality of life outcomes between patients with infection and those without infection were similar, although statistical power was limited owing to the low rate of infection. Notably, 2 of 10 patients who developed deep wound infection died of infection-related complications. CONCLUSIONS: An intraoperative sodium oxychlorosene-based infection prevention protocol helped to significantly decrease the rate of infection after spine surgery without negatively impacting other postoperative procedure-related metrics. Postoperative wound infection may be associated with higher-than-expected rate of postoperative mortality.

Treatment strategy for chondromyxoid fibroma of the sacrum.

We present a 59-year-old woman with a rare sacral chondromyxoid fibroma discovered incidentally and treated with curettage, bone grafting, and lumbopelvic fixation. At 1 year following surgery she remains symptom-free, has successfully fused her lumbopelvic construct and has no signs of tumor progression. The known literature contains only six previous reports of sacral chondromyxoid fibroma and discussion is presented on the diagnosis and treatment of this rare lesion.

Endovascular treatment and radiographic follow-up of proximal traumatic intracranial aneurysms in adolescents: case series and review of the literature.

PURPOSE: Traumatic intracranial aneurysms are rare lesions that are relatively more common in the pediatric population. Proximal traumatic aneurysms occur near the skull base. Direct surgical repair of these lesions is difficult due to the anatomically confined area, clinical status of a head injury patient, and the transmural nature of the injury. These lesions often lack a definable neck or wall suitable for clipping. While the indications and capabilities of endovascular treatment continue to expand, there are unanswered questions about the durability of treatment, especially in young patients. There are few reports examining the radiographic outcomes of endovascular treatment specifically for traumatic intracranial aneurysms. Therefore, we examined our experience treating these rare proximal lesions in an adolescent population. METHODS: A retrospective review of prospectively collected data from 2000-2008 in a large, multidisciplinary neurovascular and trauma center was performed. RESULTS: Three pediatric patients received endovascular treatment for traumatic intracranial aneurysms near the skull base. All patients had successful obliteration of their lesion without vessel sacrifice; however, two patients required multiple procedures for coil compaction or refilling of the aneurysm. There were no complications or ischemic events related to treatment. Follow-up imaging ranged from 6 months to 3.5 years. CONCLUSIONS: Traumatic intracranial aneurysms at the skull base can be successfully treated with endovascular methods; however, close follow-up is necessary.
