Factors associated with return to duty and need for subsequent procedures after calcaneus open reduction internal fixation in the military.

INTRODUCTION: Calcaneus fractures can be devastating injuries, and operative treatment is fraught with complications. We are unaware of any studies evaluating all calcaneus fractures, both open and closed, treated operatively in the military. The purpose of this study is to evaluate all calcaneus fractures that required open reduction internal fixation to determine soldiers' ability to return to work and the need for additional surgeries. METHODS: All active-duty patients undergoing open reduction internal fixation of calcaneus fractures from 2010-2016 were identified utilizing the Military Health System Management Analysis and Reporting Tool (M2). Armed Forces Health Longitudinal Technology Application (AHLTA) was utilized to determine comorbid medical conditions, subsequent procedures, surgical outcomes, and duty status within the military. RESULTS: Three hundred seventy-five active-duty service members who met our inclusion/exclusion criteria were identified. One hundred fifty-one patients (55.1%) sustained their calcaneus fracture as a result of a blast injury. One hundred sixty (59.3%) patients required separation from the military as a result of their injury. Among patients who required a subsequent procedure, thirty-four patients (9.1%) required a subtalar arthrodesis, and thirty-two patients (8.5%) eventually required a below knee amputation. Blast as mechanism of injury was the single most predictive variable for patients requiring separation from the military (Odds Ratio 16.2, p< .001), requiring a subsequent procedure (Odds Ratio 8.4, p < .001), and for requiring a below knee amputation (Odds Ratio 47.3, p < .001). CONCLUSION: Calcaneus fractures treated operatively in the military are often caused by blast injuries, and have a high rate of requiring subsequent procedures, amputation, and separation from the military.

Suture Button versus Screw Fixation for Distal Tibiofibular Injury and Expected Value Decision Analysis.

Patient preference for fixation technique of syndesmotic injury in the presence of an ankle fracture is not known. This study followed a five-step process for expected value decision analysis: decision tree, outcome probabilities, expected patient values, foldback analysis, and sensitivity analysis. Outcome variables were "well" (cases that did not require further procedures or suffer any complications related to surgery), surgical site infection (SSI), loss of reduction (LOR), hardware removal (HWR), and malreduction. The systematic review included 22 studies including 358 patients who underwent suture button fixation and 739 who underwent screw fixation. Outcome probabilities for suture button fixation were 76.4% well, 6.2% SSI, 5.4% LOR, 10.4% HWR, and 1.6% malreduction. Outcome probabilities for screw fixation were 47.1% well, 4.3% SSI, 8.1% LOR, 30.7% HWR, and 9.8% malreduction. After the survey and foldback analysis, overall utility values for suture button and screw fixation were 7.46 and 4.78, respectively. One-way sensitivity analysis revealed that the overall utility value for suture button fixation was greater than the utility value of screw fixation under all circumstances except when the rate of malreduction for suture button fixation was theoretically elevated to 85%. Level of evidence: therapeutic, level IV.

Impact of the Fascia Iliaca Block on Pain, Opioid Consumption, and Ambulation for Patients With Hip Fractures: A Prospective, Randomized Study.

OBJECTIVES: To determine the effect of the fascia iliaca block (FIB) on patients undergoing surgery for hip fractures. DESIGN: Prospective, randomized controlled trial. SETTING: Level I trauma center. PATIENTS/PARTICIPANTS: Patients (N = 97) undergoing surgery for hip fractures were prospectively randomized to receive either a perioperative FIB (FIB group) or no block (control group) from February 2018 to April 2019. MAIN OUTCOME MEASURES: Visual analog scale (VAS) score, morphine milligram equivalents, and postoperative ambulatory distance. RESULTS: Fifty-seven patients were randomized to the FIB group, and 40 patients were randomized to the control group. Eighteen patients crossed over from the FIB to the control group, and 12 patients crossed over from the control to the FIB group. In the intent-to-treat analysis, demographic data, mechanism of injury, radiographic fracture classification, and surgical procedure were similar between the 2 groups. The FIB group consumed fewer morphine milligram equivalents before surgery (13 vs. 17, P = 0.04), had a trend toward an improved visual analog scale score on postoperative day 2 (0 vs. 2 P = 0.06), and walked a farther distance on postoperative day 2 (25' vs. 2', P = 0.09). A greater proportion of the FIB group were discharged home (50.9% vs. 32.5%, P = 0.05). There were no differences in opioid-related, block-related, or medical complications between groups. In the as-treated and per-protocol analyses, there were no significant differences. CONCLUSIONS: A single perioperative FIB for patients with hip fractures undergoing surgery may decrease opioid consumption and increase the likelihood that a patient is discharged home. LEVEL OF EVIDENCE: Therapeutic Level II. See Instructions for Authors for a complete description of levels of evidence.
