A solution to gender inequity in surgery? Better caregiving policies.

SUMMARY: Attitudes toward women in surgery appear to be shifting in a positive direction. Why, then, do women still represent only 27% of surgeons in Canada? The answer may, at least in part, lie in the field's inability to adequately accommodate caregiving duties, which are still disproportionately "women's responsibilities" in our society. Although most Canadian academic centres now have paid maternity leave policies for trainees and faculty, these do not necessarily apply to surgeons working in the community, nor do they always reflect what occurs in practice. The perceived inability of the field to accommodate both personal and professional duties is often a significant deterrent to young women considering a career in surgery. In this commentary, we explore the need to address the "caregiver problem" as an important step toward achieving gender equity in surgery.

Attitudes and trends in the use of radiolucent spinal implants: A survey of the North American Spine Society section of spinal oncology.

Background: In spinal oncology, titanium implants pose several challenges including artifact on advanced imaging and therapeutic radiation perturbation. To mitigate these effects, there has been increased interest in radiolucent carbon fiber (CF) and CF-reinforced polyetheretherketone (CFR-PEEK) implants as an alternative for spinal reconstruction. This study surveyed the members of the North American Spine Society (NASS) section of Spinal Oncology to query their perspectives regarding the clinical utility, current practice patterns, and recommended future directions of radiolucent spinal implants. Methods: In February 2021, an anonymous survey was administered to the physicians of the NASS section of Spinal Oncology. Participation in the survey was optional. The survey contained 38 items including demographic questions as well as multiple-choice, yes/no questions, Likert rating scales, and short free-text responses pertaining to the "clinical concept", "efficacy", "problems/complications", "practice pattern", and "future directions" of radiolucent spinal implants. Results: Fifteen responses were received (71.4% response rate). Six of the participants (40%) were neurosurgeons, eight (53.3%) were orthopedic surgeons, and one was a spinal radiation oncologist. Overall, there were mixed opinions among the specialists. While several believed that radiolucent spinal implants provide substantial benefits for the detection of disease recurrence and radiation therapy options, others remained less convinced. Ongoing concerns included high costs, low availability, limited cervical and percutaneous options, and suboptimal screw and rod designs. As such, participants estimated that they currently utilize these implants for 27.3% of anterior and 14.7% of all posterior reconstructions after tumor resection. Conclusion: A survey of the NASS section of Spinal Oncology found a lack of consensus with regards to the imaging and radiation benefits, and several ongoing concerns about currently available options. Therefore, routine utilization of these implants for anterior and posterior spinal reconstructions remains low. Future investigations are warranted to practically validate these devices' theoretical risks and benefits.

Calcified Thoracic Disc Herniations in the Elderly: Revisiting the Laminectomy for Single Level Disease.

STUDY DESIGN: Retrospective case series. OBJECTIVES: Calcified thoracic disc herniations in the elderly present with a variety of clinical conditions and the treatment is a source of significant debate. Decompression of the disc space is done through anterior, lateral, posterolateral, and posterior approaches. There is significant morbidity of thoracic disc herniation and associated decompression. METHODS: The present report is a case series of 8 elderly patients with calcified discopathy who received a simple laminectomy without decompression of the disc space. RESULTS: Postoperatively, 5 patients mobilized independently, 2 with a walker, and 1 patient was nonambulatory. Two patients improved 1 ASIA (American Spinal Injury Association Impairment Scale) score, 1 patient improved 2 ASIA scores, and 3 patients had no change in ASIA score. CONCLUSION: In our experience, thoracic disc herniations require a technically difficult decompression and overall the complications are significant. We present a series of 8 patients who generally improved from a simple laminectomy and consider this a viable procedure for patients too unwell to undergo direct disc decompression.

Use of incisional vacuum-assisted closure in the prevention of postoperative infection in high-risk patients who underwent spine surgery: a proof-of-concept study.

OBJECTIVE: This proof-of-concept study was conducted to determine whether negative-pressure wound therapy, through the use of incisional vacuum-assisted closure (VAC), is associated with a reduction in surgical site infections (SSIs) when compared to standard wound dressings in patients undergoing open posterior spinal fusion who have a high risk of infection. METHODS: A total of 64 patients were examined; 21 patients received incisional VAC application (VAC group) versus 43 diagnosis-matched patients who received standard wound dressings (control group). Patients in the VAC group were prospectively enrolled in a consecutive series between March 2013 and March 2014 if they met the following diagnostic criteria for high risk of infection: posterior open surgery across the cervicothoracic junction; thoracic kyphosis due to metastatic disease; high-energy trauma; or multilevel revision reconstructive surgery. Patients in the VAC group also met one or more comorbidity criteria, including body mass index ≥ 35 or < 18.5, diabetes, previous radiation at surgical site, chemotherapy, steroid use, bedridden state, large traumatic soft-tissue disruption, or immunocompromised state. Consecutive patients in the control group were retrospectively selected from the previous year by the same high-risk infection diagnostic criteria as the VAC group. All surgeries were conducted by the same surgeon at a single site. The primary outcome was SSI. All patients had 1 year of follow-up after their surgery. Baseline demographics, intraoperative parameters, and postoperative wound infection rates were compared between groups. RESULTS: Patient demographics including underlying comorbidities were similar, with the exception that VAC-treated patients were malnourished (p = 0.020). VAC-treated patients underwent longer surgeries (p < 0.001) and required more postoperative ICU admissions (p = 0.039). The median length of hospital stay was not different between groups. In total, 9 control patients (21%) developed an SSI, versus 2 VAC-treated patients (10%). CONCLUSIONS: Patients in this cohort were selected to have an increased risk of infection; accordingly, the rate of SSI was high. However, negative-pressure wound therapy through VAC application to the postoperative incision resulted in a 50% reduction in SSI. No adverse effects were noted secondary to VAC application. The preliminary data confirm the authors' proof of concept and strongly support the need for a prospective randomized trial.
