Use of the Dedicated Orthopaedic Trauma Room for Open Tibia and Femur Fractures: Does It Make a Difference?

OBJECTIVE: To assess the "Dedicated Orthopaedic Trauma Operating Room" (DOTOR) effect on management and outcomes of open tibia and femur fractures. DESIGN: Retrospective chart review. LOCATION: University Level I Trauma Center. METHODS: Patients categorized into those managed in the DOTOR versus those managed in a standard on-call operating room (OCOR). Data collected include patient and injury characteristics, time to debridement, and patient outcomes. RESULTS: A total of 297 patients with 347 open tibia and femur fractures were included; 154 patients (174 fractures) were managed in the DOTOR group and 143 patients (170 fractures) were managed in the OCOR group. The average time to debridement was significantly longer for DOTOR (12.9 hours) versus OCOR (5.4 hours). The DOTOR group was 9 times less likely to undergo debridement within 6 hours. The number of patients debrided within 24 hours was similar (90% for DOTOR vs. 96% OCOR). The rate of primary fracture union was significantly higher in the DOTOR (73.2% vs. 56.6%). OCOR patients were twice as likely to have an unplanned surgery. Rates of infection, nonunion, and amputation were similar. CONCLUSION: Despite earlier access to the Operating room for debridement in the OCOR group, there was no difference in the infection rate compared with the DOTOR group. However, patients managed in the DOTOR group were more likely to go on to uncomplicated fracture union and less likely to have an unplanned surgery. LEVEL OF EVIDENCE: Therapeutic Level III.

What Is Important Besides Getting the Bone to Heal? Impact on Tissue Injury Other Than the Fracture.

Fracture surgeons do a great job of managing bone issues, but they may overlook the associated soft tissue injuries that play a significant role in the final outcome after musculoskeletal injury. The soft tissue reconstruction ladder can help guide reconstructive procedures based on the least complex procedure that allows the best chance of fracture healing. Muscle injury, volume loss, and deconditioning occur with traumatic injury and during the recovery phase. Neuromuscular stimulation, nutrition, and strength training are potential ways to aid in recovery. Complex periarticular knee injuries have a high rate of associated soft tissue injuries that may affect outcome if associated with knee instability. Identifying and addressing these injuries can increase the likelihood of a good outcome. Articular cartilage loss can make articular reconstruction impossible. Large fresh osteoarticular allografts can be a reconstructive option. Addressing all the damaged structures involved with a fracture may be the next step in improving patient outcomes.

Working length and proximal screw constructs in plate osteosynthesis of distal femur fractures.

BACKGROUND: The study purpose is to evaluate the working length, proximal screw density, and diaphyseal fixation mode and the correlation to fracture union after locking plate osteosynthesis of distal femoral fractures using bridge-plating technique. METHODS: A four-year retrospective review was performed to identify patients undergoing operative fixation of distal femur fractures with a distal femoral locking plate using bridge-plating technique for the metadiaphyseal region. Primary variables included fracture union, secondary surgery for union, plate working length, and diaphyseal screw technique and configuration. Multiple secondary variables including plate metallurgy and coronal plane fracture alignment were also collected. RESULTS: Ninety-six patients with distal femur fractures with a mean age 60 years met inclusion criteria. None of the clinical parameters were statistically significant indicators of union. Likewise, none of the following surgical technique parameters were associated with fracture union: plate metallurgy, the mean working length, screw density and number of proximal screws and screw cortices. However, diaphyseal screw technique did show statistical significance. Hybrid technique had a statistically significant higher chance of union when compared to locking (p=0.02). All proximal locking screw constructs were 2.9 times more likely to lead to nonunion. CONCLUSIONS: Plating constructs with all locking screws used in the diaphysis when bridge-plating distal femur locking plates were 2.9 times more likely to incur a nonunion. However, other factors associated with more flexible fixation constructs such as increased working length, decreased proximal screw number, and decreased proximal screw density were not significantly associated with union in this study.

Symptomatic Implant Removal Following Dual Mini-Fragment Plating for Clavicular Shaft Fractures.

OBJECTIVES: To determine the proportion of patients requiring secondary surgery for symptomatic implant removal after open reduction, internal fixation using dual mini-fragment plating technique for clavicular shaft fractures. DESIGN: Retrospective observational study. SETTING: Single university Level 1 trauma center. PATIENTS: Eighty-one patients treated with open reduction, internal fixation using dual mini-fragment plating technique for clavicular shaft fractures (OTA/AO 15-B1, B2, and B3) with minimum 12-month follow-up (median 477 days; range 371-1549 days). INTERVENTION: Open reduction, internal fixation using dual mini-fragment plating technique for clavicular shaft fractures. MAIN OUTCOME MEASUREMENTS: Incidence of secondary surgery, QuickDASH (Disabilities of the Arm, Shoulder, and Hand) scores. RESULTS: Six of 81 patients (7.4%) underwent secondary surgery for implant removal for any reason. Of these, 3 (3.7%) underwent symptomatic implant (soft-tissue irritation) removal, 2 (2.5%) required implant removal in the setting of infection, and 1 patient (1.2%) required revision open reduction internal fixation for early implant failure. The mean QuickDASH score in this series was 8.44 (±6.94, range 0-77.27). The associated implant cost of the typical construct utilized in this series was $1511.38. The mean surgical time was 97 minutes (range 71-143 minutes). CONCLUSIONS: The utilization of a dual mini-fragment plating technique in the treatment of clavicular shaft fractures results in a low rates of secondary surgery for symptomatic implant removal (3.7%) and similar QuickDASH scores when compared with historical controls treated with 3.5-mm plates placed on the superior clavicle. Potential disadvantages in using this technique include a higher surgical implant cost and length of surgery. LEVEL OF EVIDENCE: Therapeutic Level IV.

Early femur fracture fixation is associated with a reduction in pulmonary complications and hospital charges: a decade of experience with 1,376 diaphyseal femur fractures.

BACKGROUND: Early fixation (<24 hour) of femur fractures with an intramedullary nail (IMN) has been associated with a decreased incidence of pulmonary complication (PC) in stable trauma patients. Early fixation is in accordance with the "two-hit" hypothesis, that is, an increase in proinflammatory markers during Days 3 to 5 after injury, increases the risk of developing a PC. We hypothesized that early IMN fixation of femur fractures would be associated with a decreased incidence of PC, hospital stay, and overall charges. METHODS: A retrospective review of all trauma patients with diaphyseal femur fractures was performed from January 2000 through December 2010 at an academic Level 1 trauma center. The cohort was divided into those who underwent early fixation (<24 hours) and delayed fixation (≥24 hours). Multivariable logistic regression modeling was used to adjust for the anatomic (Injury Severity Score [ISS]) and physiologic (Revised Trauma Score [RTS]) severity of injury. The primary outcome of interest was PC, defined as the presence of pneumonia (PNA), pulmonary embolism, or adult respiratory distress syndrome. Continuous variables are expressed as mean (SD). The analysis was repeated for patients with an ISS of greater than 15 and an ISS of greater than 25. RESULTS: During the study period, 1,755 patients were admitted with a diaphyseal femur fracture, of whom 1,376 patients underwent primary IMN. A total of 1,032 (75%) underwent early fixation (median, 7.4 hours; interquartile range [IQR], 3.7-12.9 hours), and 344 (25%) underwent delayed fixation (median, 40.9 hours; IQR, 31.0-64.9 hours). The early fixation group had lower ISS (median [IQR], 10 [10-19] vs. 17.5 [10-27]; p < 0.001) and a higher RTS (median [IQR], 7.84 [7.84-7.84] vs. 7.84 [7.84-7.84]; p < 0.001). PC were reduced in the early fixation group, (3.9% vs. 13.4%, p < 0.001). Specifically, there was a decreased incidence of PNA (2% vs. 11%, p < 0.001), pulmonary embolism (2% vs. 4%, p < 0.21), and adult respiratory distress syndrome (0.002% vs. 0.02%, p < 0.001). After adjustment for anatomic (ISS) and physiologic (RTS) indices of injury severity, early fixation was independently associated with a reduction in PC (odds ratio, 0.43; 95% confidence interval, 0.25-0.72; p = 0.002). The early fixation group also had a decrease in hospital length of stay (median [IQR], 6 [4-11] vs. 10 [6-17]; p < 0.001), ventilator days (median [IQR], 0 [0-0] vs. 0 [0-4]; p < 0.001), and hospital charges (median [IQR], $59,561 [$38,618-$106,780] vs. $97,018 [48,249-205,570]; p < 0.001). Mortality was low in both groups (0.4% vs. 1.7%, p < 0.01). Similar results were seen in patients with an ISS of greater than 15 and ISS of greater than 25. CONCLUSION: Controlling for anatomic and physiologic severity of injury, early femoral IMN was associated with an almost 60% reduction in odds of developing PCs. Early fixation was also associated with a reduction ventilator days, hospital length of stay, and overall hospital charges. As the list of "never events" continues to expand and improving quality of care while reducing costs is emphasized, early (<24 hours) definitive operative intervention seems to decrease complications, achieve early hospital discharge, and reduce hospital charges.
