Background: Given the neurotrauma that soldiers might face during wars, a byproduct of such devastating neurosurgical conditions can be novel data, which can act as a catalyst for potentially paradigm-shifting research. We aimed to identify the impact of major U.S. military campaigns on military neurosurgery literature across defined time periods.
Methods: A comprehensive Elsevier's Scopus database search was performed to capture all published and indexed studies from 1915 to 2021 relevant to military neurosurgery. A discrete set of validated informetric metadata parameters were extracted and analyzed using productivity analysis, citation analysis, keyword analysis, text mining, content analysis, and collaboration network mapping.
Results: Our search yielded 2216 documents. Annual scientific production since 1915 grew at a compounded rate of 6.1% per year, with the most significant increases during U.S. military campaigns (coefficient = 42.9, P < 0.001) and following the introduction of the Department of Defense Trauma Registry in 2007 (coefficient = 114.5; P < 0.001). Each war had a direct influence on military neurosurgery literature growth (P < 0.05), with the most prominent following the Afghanistan war. The journals with the most publications on military neurosurgery were Military Medicine (n = 168) and Journal of Head Trauma. The topmost cited author was Hoge et al. (N = 2083), while the topmost cited country was the United States (N = 1098).
Conclusions: Since World War II, the military has contributed significant historical developments to neurosurgery, the most prominent being after the Iraq and Afghanistan wars and the introduction of the Department of Defense Trauma Registry.
