Civilian Ballistic Femoral Shaft Fractures Compared With Blunt Femur Shaft Fractures.

OBJECTIVE: To assess ballistic femoral shaft fracture outcomes in comparison with closed and open femoral shaft fractures sustained by blunt mechanisms. We hypothesized that ballistic femoral shaft fractures would have similar outcomes to blunt open fractures. DESIGN: Retrospective cohort study. SETTING: Academic Level I trauma center. PARTICIPANTS: Patients 16 years and older presenting with ballistic (140), blunt closed (317), or blunt open (71) femoral shaft fractures. MAIN OUTCOMES: Unplanned return to operating room, fracture-related infection, soft tissue reconstruction, nonunion, implant failure, length of stay, Injury Severity Scores, hospital charges, and compartment syndrome. RESULTS: A total of 528 femoral shaft fractures were identified. A group of 140 ballistic fractures and comparison groups of all femoral shaft fractures sustained by blunt mechanisms and treated with intramedullary nailing were included in the analysis. Among the 2 subgroups of nonballistic injuries, 317 were blunt closed fractures and 71 were blunt open fractures. The ballistic group was associated with a 3-fold increase in overall complications (30%) compared with the blunt closed group (10%, P < 0.001), had a higher occurrence of thigh compartment syndrome (P < 0.001), and required more soft tissue reconstruction (P < 0.001) than either of the blunt fracture groups. CONCLUSIONS: Ballistic femoral shaft fractures do not perfectly fit with blunt closed or open femoral fractures. A high index of suspicion for the development of thigh compartment syndrome should be maintained in ballistic femoral shaft fractures. The overall rates of nonunion and infection were comparable between all groups, but the all-cause complication rate was significantly higher in the ballistic group compared with the blunt closed group.

Risk Factors for Deep Infection and Conversion Total Hip Arthroplasty After Operative Combined Pelvic Ring and Acetabular Fractures.

OBJECTIVES: To determine risk factors for deep infection and conversion total hip arthroplasty (THA) after operative management of combined pelvic ring and acetabular injuries. DESIGN: Retrospective case control study. SETTING: Level 1 trauma center. PATIENTS AND INTERVENTION: We reviewed 150 operative combined pelvic ring and acetabular injuries at our institution from 2010 to 2019, with an average follow-up of 690 (90-3282) days. MAIN OUTCOME MEASUREMENTS: Deep infection and conversion THA. RESULTS: Patients who developed deep infection (N = 17, 11.3%) had higher rates of hip dislocation ( P = 0.030), intraoperative transfusion ( P = 0.030), higher body mass index (BMI) ( P = 0.046), increased estimated blood loss ( P < 0.001), more intraoperative units transfused ( P = 0.004), and longer operative times ( P = 0.035). Of the 84 patients with 1-year follow-up, 24 (28.6%) required conversion to THA. Patients requiring conversion THA were older ( P = 0.022) and had higher rates of transverse posterior wall fracture pattern ( P = 0.034), posterior wall involvement ( P < 0.001), hip dislocation ( P = 0.031), wall comminution ( P = 0.002), and increased estimated blood loss ( P = 0.024). The order of the pelvic ring versus acetabular fixation did not affect rates of conversion to THA ( P = 0.109). Multiple logistic regression showed that an increased number of intraoperative units transfused [adjusted odds ratio (aOR) = 1.56, 95% confidence interval (CI) = 1.16-2.09, P = 0.003] and higher BMI (aOR = 1.10, 95% CI = 1.01-1.16, P = 0.024) were independently associated with an increased odds of deep infection. Posterior wall involvement was independently associated with an increased odds of conversion THA (aOR = 5.73, 95% CI = 1.17-27.04, P = 0.031). CONCLUSIONS: Rates of deep infection and conversion THA after operative fixation of combined injuries were 11.3% and 28.6%, respectively. Higher average BMI and number of intraoperative units of blood transfused were independently associated with deep infection, whereas posterior wall involvement was independently associated with conversion to THA in these patients. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Quality Improvement Tools in Total Joint Arthroplasty: A Systematic Review.

Systems review and quality improvement (QI) is a significant need within orthopaedic surgery. The focus of this paper is to systematically review QI principles utilized in total joint arthroplasty to determine most successful QI tools. A systematic search on MEDLINE/Pubmed, Embase, Cochrane Library and other sources was conducted from September 1991 through October 2018. The three primary improved outcomes from each article were recorded along with the date, author and subspecialty. Thirty-four eligible studies related to joint arthroplasty were identified for inclusion in the systematic review. The most common outcomes that were improved in these publications were: length of stay (LOS), cost, medication management, and patient education. Lean, clinical care pathways (CCP), plan-do-check-act (PDCA), and shared decision-making improved those metrics. Four metrics were found that were consistently improved by certain quality improvement tools: LOS, cost, medication management, and patient education. Further research is warranted to continue to build a framework for quality improvement in orthopaedic surgery. (Journal of Surgical Orthopaedic Advances 30(3):125-130, 2021).
