Introduction: Diabetes mellitus (DM) is a risk factor of infection. Although DM has been associated with worse functional outcomes after acetabular fracture, literature regarding the effect of DM on surgical site infection and other early complications is lacking., Methods: A 20-year registry from a level 1 trauma center was queried to identify 134 patients with DM and 345 nondiabetic patients with acetabular fractures., Results: The diabetic patient population was older (57.2 versus 43.2; P < 0.001) and had higher average body mass index (33.6 versus 29.5; P < 0.001). Eighty-three patients with DM and 270 nondiabetics were treated surgically (62% versus 78%; P < 0.001). Diabetic patients who were younger (54.6 versus 61.4; P = 0.01) with fewer comorbidities (1.7 versus 2.2; P = 0.04) were more frequently managed surgically. On univariate analysis, patients with DM more commonly developed any early infection (28.4% versus 21%; P = 0.049) but were no more likely to develop surgical site infection, or other postoperative complications. Older patient age, length of stay, baseline pulmonary disease, and concurrent abdominal injury were independent predictors of postoperative infection other than surgical site infection. Diabetics that developed infection had more comorbidities (2.4 versus 1.5; P < 0.001) and higher Injury Severity Score (24.1 versus 15.8; P = 0.003), and were more frequently insulin-dependent (72.7% versus 41%; P = 0.01)., Discussion: Independent of management strategy, diabetic patients were more likely to develop an infection after acetabular fracture. Insulin dependence was associated with postoperative infection on univariate analysis. Optimal selection of surgical candidates among patients with DM may limit postoperative infections., (Copyright © 2024 The Authors.

Introduction: The purpose of this study was to describe the practice of postmobilization radiography after lateral compression type 1 pelvis ring injury. We hypothesized that postmobilization radiographs would be more frequent over time and would not influence treatment., Methods: Displacement of pelvis ring injury on initial and final plain radiographs was measured. Frequency of postmobilization radiography was determined, and the impact on treatment and final radiographical outcome were assessed., Results: Of the 156 patients reviewed, 98 (62.8%) were women and mean age was 60.1 years. Thirty-three of 156 patients (21.2%) had a postmobilization radiograph. Over 5 years, radiographs increased to 67% of presenting patients. None of the patients who received postmobilization plain radiographs (n = 33) had any change in clinical plan afterward; all continued with nonsurgical care. Initial fracture characteristics and alignment were no different for patients with postmobilization radiographs. Final alignment was unchanged in nearly 70%. Overall, 74% of all nonsurgical patients experienced no change in alignment, with similar rates among the patients with postmobilization radiographs., Discussion: Patients with an lateral compression type 1 fracture demonstrated no changes in care after receiving postmobilization radiographs. However, the frequency of postmobilization radiographs increased over time, denoting opportunities to reduce costs and to improve efficiency and safety., (Copyright © 2023 The Authors.

Introduction: No guidelines exist for recommending return to driving. This study will examine time to brake (TTB) after lower extremity injuries versus in uninjured people. The potential effect of various types of lower extremity injuries on TTB will be measured., Methods: Patients with injuries to the pelvis, hip, femur, knee, tibia, ankle, and foot underwent testing using a driving simulator to assess TTB. Comparison was with a control group of uninjured people., Results: Two-hundred thirty-two patients with lower extremity injuries participated. The majority were in the tibia and ankle regions (47%). Mean TTB for control subjects was 0.74 seconds, compared with 0.83 for injured patients, noting a 0.09-second difference (P = 0.017). Left-sided injuries averaged TTB of 0.80 seconds, right-sided injuries averaged TTB of 0.86 seconds, and bilateral injuries averaged TTB of 0.83 seconds, all prolonged versus control subjects. The longest TTB was exhibited after ankle and foot injuries (0.89 seconds) while the shortest was after tibial shaft fractures (0.76 seconds)., Discussion: Any lower extremity injury caused a prolonged TTB compared with control patients. Left, right, and bilateral injuries all had longer TTB. Ankle and foot injuries experienced the longest TTB. Additional investigation is warranted to develop safe guidelines for return to driving., Competing Interests: This research was supported by a grant from the Orthopaedic Trauma Association.

Introduction: Among elderly patients, anterior column posterior hemitransverse (ACPHT) and associated both column (ABC) are common acetabular fracture patterns after low-energy mechanisms. Given the paucity of outcomes data in this cohort, the goal of this study was to determine the favorability of results with surgical versus nonsurgical management. Secondarily, factors linked with poor functional outcomes were assessed., Methods: Over a 16-year period, 81 patients aged ≥60 years with 82 ACPHT and ABC acetabular fractures were evaluated. Retrospectively, patient demographics, injury details, and early and late complications were collected. Functional outcomes were assessed with the Musculoskeletal Function Assessment (MFA) after a minimum of 12 months of follow-up., Results: During the study period, 81 patients sustained 82 ACPHT (n = 35, 43%) or ABC (n = 47) fractures, most secondary to low-energy falls (71%). Patients managed surgically were younger, had higher-energy mechanisms, and more often had an associated hip dislocation or marginal impaction (all P < 0.05). Of note, 42.3% and 18.5% of patients had early and late complications, respectively, with no differences between surgical and nonsurgical groups. Posttraumatic arthrosis (PTA) was noted in 27% overall (36% surgical versus 16% nonsurgical, P = 0.10). The mean MFA score was 25.2 after 59 months. Better outcomes were associated with high-energy mechanisms, multiple injuries, and surgical management (all P < 0.05). The worst MFA outcomes were among patients with PTA (40.2) and those requiring a secondary procedure (45.7), both P < 0.05., Discussion: Nonsurgical management had a low rate of PTA. Mitigating PTA and decreasing the rate of secondary surgeries seem crucial achieving satisfactory outcomes. Higher-energy injuries benefit from open reduction and internal fixation, as indicated by better MFA scores., (Copyright © 2022 The Authors.
