Risk factors affecting hip fracture patterns in an elderly Korean patient population.

Hip fracture in the elderly patient population, particularly the Korean patient cohort, is one of the most serious complications of osteoporosis and currently increasing alongside age. In this study, we attempted to identify various factors that could either indicate the risk for an intertrochanteric or femoral neck fracture in an osteoporotic Korean hip fracture patient cohort ≥ 65 years old. A retrospective analysis of 168 patients was performed for those who underwent surgical treatment for either an intertrochanteric or femoral neck fracture at Daegu Catholic University Medical Center from January 2013 to December 2015. Inclusion criteria included patients who sustained a intertrochanteric or femoral neck fracture between the designated time frame, ≥65 years old, and of Korean ethnicity. Differences between the T-score and Z-score regarding bone mineral density (BMD) and the relationship between BMD and subtype of the fracture for the intertrochanteric (n = 92) and femoral neck fracture (n = 76) groups were obtained. Demographical factors (age, sex, weight, height, and body mass index [BMI]) were analyzed as potential risk factors for intertrochanteric or femoral neck fractures using software. Of the total 168 patients, mean weight and BMI values were found to be lower in the intertrochanteric fracture group (P = .033) compared to the femoral neck fracture group (P = .044). Additionally, Z-scores for the intertrochanteric fracture group were lower in the trochanter (P = .030), intertrochanteric (P = .029), and Ward's triangle (P = .029) regions. Regarding the intertrochanteric fracture group, the A3 subgroup showed lower T-scores of the trochanteric region than the A1 fracture subgroup (P = .010). In an elderly Korean hip patient cohort, lower body weight, BMI, and BMD Z-scores are correlated with a higher incidence of intertrochanteric fractures when compared to femoral neck hip fractures.

Acute respiratory distress syndrome after treating ipsilateral femoral shaft and neck fracture with reamed intramedullary nailing in an asymptomatic COVID-19 patient.

Currently, it is quite difficult to determine the best timeframe of operative treatment, as well as conduct surgery on asymptomatic COVID-19 patients due to misunderstandings and unawareness of the patient's inflammation state. Caution needs to be taken in specific patient cohorts, particularly those with femoral shaft fractures, who are more likely to develop diseases like acute respiratory distress syndrome after a procedure like intramedullary nailing. In this case report, a 36-year-old patient suffered a motorcycle accident in which he suffered an ipsilateral femoral shaft and neck fracture of the hip. The patient's screening test for COVID-19 was positive before admission. Because the patient did not display any COVID-19-related symptoms upon arrival to the hospital, surgical fixation with a reamed intramedullary femoral nail was performed. Despite having a successful post-surgical outcome, the patient was diagnosed with acute respiratory distress syndrome 36 h after surgery, recovering fully after about 2 weeks. To prevent subsequent complications such as acute respiratory distress syndrome in a high inflammatory state patient like COVID-19, the respiratory status and the degree of systemic inflammation should be considered precisely when determining the surgical timing and method.
