Rate of Return to Military Active Duty After Single and 2-Level Anterior Cervical Discectomy and Fusion: A 4-Year Retrospective Review.

BACKGROUND: Over the years of rigorous of military service, military personnel may experience cervical spondylosis and radiculopathy. Given the frequency of this occurrence, the capacity to return to unrestricted full duty in the military after anterior cervical discectomy and fusion (ACDF) is worthy of analysis. OBJECTIVE: To identify the rate of return to full, unrestricted active duty after single and 2-level anterior cervical discectomy, and fusion surgery in military personnel. METHODS: A retrospective chart review was performed at a tertiary care military treatment facility for all active duty personnel who underwent a single or 2-level ACDF over a 4-yr period. Patient and procedural data were collected to include single or 2-level fusion, indication for surgery, fusion level, tobacco use, age, and military rank. Fischer's Exact and Wilcoxon Rank Sum tests were used to identify statistically significant differences in the rate of return to active duty. RESULTS: A total of 132 anterior cervical discectomy and fusions were analyzed. One hundred sixteen patients (88%) were able to return to unrestricted full active duty, while the remaining 16 required separation from the military for continued pain or disability. The return to active duty rate was significantly higher in service members with a rank of E7 or above (99%) than those E6 and below (73%). There was a strong association between the presence of a pseudoarthrosis and the capacity to return to full duty (P = .013). CONCLUSION: Both single and 2-level ACDFs have high overall success with an 88% rate of return to full duty.

Early venous thromboembolism chemoprophylaxis in combat-related penetrating brain injury.

OBJECTIVE Traumatic brain injury (TBI) is independently associated with deep vein thrombosis (DVT) and pulmonary embolism (PE). Given the numerous studies of civilian closed-head injury, the Brain Trauma Foundation recommends venous thromboembolism chemoprophylaxis (VTC) after severe TBI. No studies have specifically examined this practice in penetrating brain injury (PBI). Therefore, the authors examined the safety and effectiveness of early VTC after PBI with respect to worsening intracranial hemorrhage and DVT or PE. METHODS The Kandahar Airfield neurosurgery service managed 908 consults between January 2010 and March 2013. Eighty of these were US active duty members with PBI, 13 of whom were excluded from analysis because they presented with frankly nonsurvivable CNS injury or they died during initial resuscitation. This is a retrospective analysis of the remaining 67 patients. RESULTS Thirty-two patients received early VTC and 35 did not. Mean time to the first dose was 24 hours. Fifty-two patients had blast-related PBI and 15 had gunshot wounds (GSWs) to the head. The incidence of worsened intracranial hemorrhage was 16% after early VTC and 17% when it was not given, with the relative risk approaching 1 (RR = 0.91). The incidence of DVT or PE was 12% after early VTC and 17% when it was not given (RR = 0.73), though this difference was not statistically significant. CONCLUSIONS Early VTC was safe with regard to the progression of intracranial hemorrhage in this cohort of combat-related PBI patients. Data in this study suggest that this intervention may have been effective for the prevention of DVT or PE but not statistically significantly so. More research is needed to clarify the safety and efficacy of this practice.

Transdural metastasis from adenocarcinoma of the prostate mimicking subdural hematoma: case report.

BACKGROUND: Metastasis of prostatic adenocarcinoma to the nervous system is extremely rare and has been infrequently reported over the last several years. We describe the presentation, evaluation, and surgical intervention of a case of metastatic prostate carcinoma to the dura. CASE DESCRIPTION: This patient presented with symptoms and physical findings consistent with a subacute subdural hematoma in the setting of recently diagnosed adenocarcinoma of the prostate. He underwent a craniotomy for presumed subdural hematoma. The pathologic diagnosis was consistent with metastatic prostatic carcinoma. CONCLUSION: This case report demonstrates the need for broad differential diagnosis in the evaluation and treatment of patients presenting with seemingly straightforward subacute subdural hematomas.
