Prevalence and Risk Factors of Postoperative Falls Following Foot and Ankle Surgery.

BACKGROUND: No study has examined the incidence of risk factors for postoperative falls following foot and ankle surgery. We investigated the incidence and risk factors for postoperative falls in foot and ankle surgery using inpatient and outpatient population. METHODS: A single fellowship-trained foot and ankle surgeon instituted collection of a postoperative fall questionnaire at 2 and 6 weeks postoperatively. A retrospective review of 135 patients with complete prospectively collected fall questionnaire data was performed. Patient demographic information, injury characteristics, comorbidities, baseline medications, length of hospital stay, visual analog scale (VAS) pain scores were collected. After univariable analysis, a multivariable binary logistic regression was conducted to assess independent risk factors for postoperative falls. RESULTS: The median (interquartile range) age was 52 (21) and body mass index was 32.7 (11.1). A total of 108 patients (80%) underwent outpatient procedures. Thirty-nine of the 135 patients (28.9%) reported experiencing a fall in the first 6 weeks after surgery. In multivariable analysis, antidepressant use (adjusted odds ratio 3.41, 95% CI 1.19-9.81) and higher VAS pain scores at 2 weeks postoperatively (adjusted odds ratio 1.27, 95% CI 1.08-1.50) were found to be independent risk factors for postoperative falls. CONCLUSION: This study found a high incidence of postoperative falls in the first 6 weeks after foot and ankle surgery. Baseline antidepressant use and higher 2-week VAS pain scores were associated with postoperative falls. Foot and ankle surgeons should discuss the risk of falling with patients especially those with risk factors. LEVEL OF EVIDENCE: Level III, retrospective cohort study at a single institution.

Systemic Complications of Obesity in Operative Acetabular Fractures.

OBJECTIVE: To determine the effect of obesity on rates of systemic complications in operatively treated acetabular fractures. DESIGN: Retrospective Case-Control study. SETTING: Level 1 Trauma Center. PATIENTS/PARTICIPANTS: All patients with acetabular fractures managed operatively from January 2015 to December 2019. Patients were divided into groups based on their body mass index (BMI) (normal weight = BMI <25 kg/m2, overweight = BMI 25-30, obese = BMI 30-40, and morbidly obese = BMI >40). INTERVENTION: Operative management of an acetabular fracture. MAIN OUTCOME MEASUREMENT: Systemic complications, including mortality, sepsis, pneumonia, acute respiratory distress syndrome, deep vein thrombosis, pulmonary embolism, or venous thrombotic event. RESULTS: A total of 428 patients were identified. One hundred nine patients (25.4%) were in normal weight, 133 (31.1%) were overweight, 133 (31.1%) were obese, and 53 (12.4%) were morbidly obese. The rate of systemic complications was 17.5%, and overall mortality rate was 0.005%. There were no significant differences between the different BMI groups in all-cause complications or any individual complications. When the morbidly obese group was compared with all other patients, there were also no significant differences in all-cause complications or any individual complications. CONCLUSION: In conclusion, in this study, there was no association with increasing BMI and inpatient systemic complications after operative management of acetabular fractures. As we continue to refine our understanding of how obesity affects outcomes after acetabular fracture surgery, other indices of obesity might prove more useful in predicting complications. In the obese population, there are well-documented risks of postoperative infections and challenges in obtaining an anatomic reduction, but the fear of postoperative systemic complications should not deter surgeons from undertaking operative management of acetabular fractures in the obese population. Because the prevalence of obesity in trauma patients continues to increase, it is incumbent on us to continue to improve our understanding of optimal treatment for our patients.

Civilian Ballistic Tibia Shaft Fractures Compared With Blunt Tibia Shaft Fractures: Open or Closed?

OBJECTIVES: To identify a group of ballistic tibia fractures, report the outcomes of these fractures, and compare them with both closed and open tibia fractures sustained by blunt mechanisms. We hypothesized that ballistic tibia fractures and blunt open fractures would have similar outcomes. DESIGN: Retrospective cohort study. SETTING: A single Level-1 trauma center. PATIENTS/PARTICIPANTS: Adult patients presenting with ballistic (44), blunt closed (179), or blunt open (179) tibia fractures. INTERVENTION: Intramedullary stabilization of tibia fracture. MAIN OUTCOMES: Unplanned reoperation, soft tissue reconstruction, nonunion, compartment syndrome, and fracture-related infection. RESULTS: Compared with the blunt closed group, the ballistic fracture group required more operations (P < 0.01), had a higher occurrence of soft tissue reconstruction (P < 0.01), and higher incidence of compartment syndrome (P = 0.02). Ballistic and blunt closed groups did not significantly differ in rates of unplanned reoperation (P = 0.67), nonunion (11.4% vs. 4.5%, P = 0.08), or deep infection (9.1% vs. 5.6%, P = 0.49). In comparison to the blunt open group, the ballistic group required a similar number of operations (P = 0.12), had similar rates of unplanned reoperation (P = 0.10), soft tissue reconstruction (P = 0.56), nonunion (11.4% vs. 17.9%, P = 0.49), and fracture-related infection (9.1% vs. 10.1%, P = 1.0) but a higher incidence of compartment syndrome (15.9% vs. 5.0%, P = 0.02). CONCLUSIONS: Ballistic tibia fractures require more surgeries and have higher rates of soft tissue reconstruction than blunt closed fractures and seem to have outcomes similar to lower severity open fractures. We found a significantly higher rate of compartment syndrome in ballistic tibia fractures than both open and closed blunt fractures. When treating ballistic tibia fractures, surgeons should maintain a high level of suspicion for the development of compartment syndrome and counsel patients that ballistic tibia fractures seem to behave like an intermediate category between closed and open fractures sustained through blunt mechanisms.
