The rise and fall of Queckenstedt's test between 1916 and 1970, a milestone in spinal cord diagnostics and why it matters

BACKGROUND AND PURPOSE

In 1916, Hans H. G. Queckenstedt (1876-1918) was the first to describe a test aimed at detecting spinal cerebrospinal fluid (CSF) space obstruction through lumbar CSF pressure measurements in paraplegic patients. For this test, bilateral jugular vein compression was applied during lumbar puncture and consecutive changes in lumbar CSF pressure were then observed. Findings were rated as normal, or indicative of incomplete or complete spinal block. This test, known as Queckenstedt's test, became widely adopted and further developed in the field.

METHODS

This systematic literature review provides an overview of the milestones in research using Queckenstedt's test.

RESULTS

Clinical research involving Queckenstedt's test was widely disseminated across the globe. In 1922, the proof of concept for Queckenstedt's test was provided by James B. Ayer (1882-1963) through simultaneous cisternal and lumbar CSF pressure measurements. He found that the cisternal (in contrast to lumbar) pressure remained responsive in cases with spinal block. The test was further refined up until the 1960s, and was considered a routine diagnostic procedure for testing of spinal canal obstruction. Developments in non-invasive spinal computed tomography and magnetic resonance imaging led to a significant decline in interest in Queckenstedt's test, and the test eventually disappeared from textbooks and clinical routine. However, at the beginning of the 21st century there was renewed interest in revealing the biomechanical properties of the CSF through advanced recording and computational techniques to complement spinal imaging.

CONCLUSION

Spine and spinal cord physicians should be familiar with Queckenstedt's test, which not only represented a milestone in spinal diagnostics, but provided a physiological framework for the appreciation of spinal cord compression that is still valid today.

Women in spine surgery: can we change the society?

BACKGROUND

Although the number of educated women and physicians, and especially neurosurgeons, is increasing worldwide, the educational opportunities, careers, and beliefs concerning female neurosurgeon's status and abilities are undermined. To date, reported studies have focused on the conditions of the work environment, work-life balance, and the academic career of female neurosurgeons. In this study, we aimed to report the patients' viewpoint and how they choose spine physicians.

METHODS

We conducted an international survey based on 19 questions in four languages (Bulgarian, Greek, English, and German). The responses of 413 individuals, unrelated to the medical field (sex, 315 female and 115 male individuals; one individual did not answer the question regarding the gender), were obtained. Except for the question regarding the patient's preference for the physician sex, the survey aimed to examine the factors that might be contributing to this choice, including education, age, heard/read recommendations/advertisements, knowledge regarding the work of the neurosurgeons/orthopedists, and their difference regarding spine surgery.

RESULTS

The majority of the participants responded that they prefer male surgeons to treat their spine. The results showed a significant correlation between the choice of a male spine surgeon and heard/read advertisements/recommendations and knowledge regarding the work of the neurosurgeon. Despite the fact that education was not related to physician selection, it was an indirect factor that led to the final choice.

CONCLUSION

Women in surgery, mainly in neurosurgery, are being treated by society in an unequal way. Female surgeons are still discriminated because of their gender. The most patients prefer female physicians to talk to, but still believe that they are incapable to perform spine surgery. We cannot stop this until we change our mindset and perception of reality.

Maxine Deborrah Hyde: First Female Graduate of Case Western Reserve University's Neurologic Surgery Residency Program and Second Black Female Neurosurgeon in the United States

BACKGROUND

The historical diversity gap in the neurosurgical workforce persists to this day. Women, despite constituting over half of the yearly total of medical school graduates, comprise only 6% of certified practicing neurosurgeons in the United States. Furthermore, Black Americans make up under 4% of U.S. neurosurgeons, despite making up around 14% of the national population. The purpose of this account is to highlight the life and career of Dr. Maxine Deborrah Hyde and illustrate the importance and necessity of diversity and inclusivity in advancing the field of neurosurgery. Through this paper, we aspire to encourage the development of new diversity initiatives.

METHODS

Original scientific and bibliographic materials of Hyde were examined, and an extensive analysis of her life was compiled.

RESULTS

Despite growing up during the era of Jim Crow, Dr. Hyde persevered and became the valedictorian of Oak Park High School. As a first-generation college student at Tougaloo College, she later earned her MS from Cleveland State University. Dr. Hyde graduated with honors from Case Western Reserve University School of Medicine in 1977. Thereafter, she became the first female and first Black graduate of Case Western's neurosurgery residency and the second Black woman to receive certification from the American Board of Neurological Surgery. Later in life, Dr. Hyde established the Beacon of Hope Scholarship Foundation to assist disadvantaged students in overcoming educational barriers.

CONCLUSIONS

Dr. Hyde was a trailblazer who overcame systematic barriers and paved the way for future generations of aspiring neurosurgeons.
