Introduction/UNASSIGNED:Distal radius fractures are the second most common fracture in the elderly population. The incidence of these fractures has increased over time, and is projected to continue to do so. The aim of this study is to utilize a validated trauma risk prediction tool to stratify middle-aged and geriatric patients with operative distal radius fractures as well as compare hospital quality metrics and inpatient hospitalization costs among the risk groups. Materials and Methods/UNASSIGNED:Patients were prospectively enrolled in an orthopedic trauma registry. The Score for Trauma Triage in Geriatric and Middle Aged (STTGMA) was calculated using patient demographics, injury severity, and functional status. Patients were then stratified into minimal-risk, moderate-risk, and high-risk cohorts based on their scores. Length of stay, need for escalation of care, complications, mortality, discharge location, 1-year patient reported outcomes, and index admission costs were evaluated. Results/UNASSIGNED:= .019). There were no complications or mortality in any of the risk groups. No patients required intensive care and all patients were discharged home. There was no difference in readmission rates, inpatient cost, or 1-year patient reported outcomes among the risk cohorts. Discussion/Conclusions/UNASSIGNED:The Score for Trauma Triage in Geriatric and Middle-Aged is able to risk-stratify patients that undergo operative intervention of distal radius fractures. Middle aged and elderly patients with isolated closed distal radius fractures can be safely managed on an outpatient basis regardless of risk. Standardized pathways can be created in the management of these injuries, thereby optimizing value-based care. Level of evidence/UNASSIGNED:Prognostic Level III.

Introduction/UNASSIGNED:The Score for Trauma Triage in the Geriatric and Middle-Aged (STTGMA) is a validated mortality risk score that evaluates 4 major physiologic criteria: age, comorbidities, vital signs, and anatomic injuries. The aim of this study was to investigate whether the addition of ASA physical status classification system to the STTGMA tool would improve risk stratification of a middle-aged and elderly trauma population. Methods/UNASSIGNED:A total of 1332 patients aged 55 years and older who sustained a hip fracture through a low-energy mechanism between October 2014 and February 2020 were included. The STTGMA and STTGMAASA mortality risk scores were calculated. The ability of the models to predict inpatient mortality was compared using area under the receiver operating characteristic curves (AUROCs) by DeLong's test. Patients were stratified into minimal, low, moderate, and high risk cohorts based on their risk scores. Comparative analyses between risk score stratification distribution of mortality, complications, length of stay, ICU admission, and readmission were performed using Fisher's exact test. Total cost of admission was fitted by univariate linear regression with STTGMA and STTGMAASA. Results/UNASSIGNED:There were 27 inpatient mortalities (2.0%). When STTGMA was used, the AUROC was 0.742. When STTGMAASA was used, the AUROC was 0.823. DeLong's test resulted in significant difference in predictive capacity for inpatient mortality between STTGMA and STTGMAASA (p = 0.04). Risk score stratification yielded significantly different distribution of all outcomes between risk cohorts (p < 0.01). STTGMAASA stratification produced a larger percentage of all negative outcomes with increasing risk cohort. Total hospital cost was statistically correlated with both STTGMAASA (p < 0.01) and STTGMA (p = 0.02). Conclusion/UNASSIGNED:Including ASA physical status as a variable in STTGMA improves the model's ability to predict inpatient mortality and risk stratify middle-aged and geriatric hip fracture patients.

Introduction/UNASSIGNED:Operative hip fractures are known to cause a loss in functional status in the elderly. While several studies exist demonstrating the association between age, pre-injury functioning, and comorbidities related to this loss of function, no studies have predicted this using a validated risk stratification tool. We attempt to use the Score for Trauma Triage for Geriatric and Middle-Aged (STTGMA) tool to predict loss of ambulatory function and need for assistive device use. Materials and Methods/UNASSIGNED:Five hundred and fifty-six patients ≥55 years of age who underwent operative hip fracture fixation were enrolled in a trauma registry. Demographics, functional status, injury severity, and hospital course were used to determine a STTGMA score and patients were stratified into risk quartiles. At least 1 year after hospitalization, patients completed the EQ-5D questionnaire for functional outcomes. Results/UNASSIGNED:Two hundred and sixty-eight (48.2%) patients or their family members responded to the questionnaire. Of the 184 patients alive, 65 (35.3%) reported a return to baseline function. Eighty-nine (48.4%) patients reported a loss in ambulatory status. Patients with higher STTGMA scores were older, had more comorbidities, reported greater need for help with daily activities, increased difficulty with self-care, and a reduction in return to activities of daily living (all p ≤ 0.001). Patients with lower STTGMA scores were more likely to never require an assistive device while those with higher scores were more likely to continue needing one (p = 0.004 and p < 0.001). Patients in the highest STTGMA risk groups were 1.5x more likely to have an impairment in ambulatory status (need for ambulatory assistive device or decreased ambulatory capacity) (p = 0.004). Discussion/UNASSIGNED:Patients in higher STTGMA risk quartiles were more likely to experience impairment after hip fracture surgery. The STTGMA tool can predict loss of ambulatory independence following hip fracture. At-risk populations can be targeted for enhanced physiotherapy and rehabilitation services for optimal return to prior functioning.

Introduction/UNASSIGNED:The purpose of this study is to determine if the risk of receiving a blood transfusion during hip fracture hospitalization can be predicted by a validated risk profiling score (Score for Trauma Triage in Geriatric and Middle Aged (STTGMA)). Materials and Methods/UNASSIGNED:A consecutive series of 1449 patients 55 years and older admitted for a hip fracture at one academic medical center were identified from a trauma database. The STTGMA risk score was calculated for each patient. Patients were stratified into risk groups based on their STTGMA score quantile: minimal risk (0-50%), low risk (50-80%), moderate risk (80-95%), and high risk (95-100%). Incidence and volume of blood transfusions were compared between risk groups. Results/UNASSIGNED:< 0.001). STTGMA was predictive of first transfusion incidence in both the preoperative and postoperative periods. There was no difference in mean total transfusion volume between the four risk groups. Conclusion/UNASSIGNED:The STTGMA model is capable of risk stratifying hip fracture patients more likely to receive blood transfusions during hospitalization. Surgeons can use this tool to anticipate transfusion requirements.

Introduction/UNASSIGNED:This study sought to investigate whether a validated trauma triage tool can stratify hospital quality measures and inpatient cost for middle-aged and geriatric trauma patients with isolated proximal and midshaft humerus fractures. Materials and Methods/UNASSIGNED:Patients aged 55 and older who sustained a proximal or midshaft humerus fracture and required inpatient treatment were included. Patient demographic, comorbidity, and injury severity information was used to calculate each patient's Score for Trauma Triage in the Geriatric and Middle-Aged (STTGMA). Based on scores, patients were stratified to create minimal, low, moderate, and high risk groups. Outcomes included length of stay, complications, operative management, ICU/SDU-level care, discharge disposition, unplanned readmission, and index admission costs. Results/UNASSIGNED:Seventy-four patients with 74 humerus fractures met final inclusion criteria. Fifty-eight (78.4%) patients presented with proximal humerus and 16 (21.6%) with midshaft humerus fractures. Mean length of stay was 5.5 ± 3.4 days with a significant difference among risk groups (P = 0.029). Lower risk patients were more likely to undergo surgical management (P = 0.015) while higher risk patients required more ICU/SDU-level care (P < 0.001). Twenty-six (70.3%) minimal risk patients were discharged home compared to zero high risk patients (P = 0.001). Higher risk patients experienced higher total inpatient costs across operative and nonoperative treatment groups. Conclusion/UNASSIGNED:The STTGMA tool is able to reliably predict hospital quality measures and cost outcomes that may allow hospitals and providers to improve value-based care and clinical decision-making for patients presenting with proximal and midshaft humerus fractures. Level of Evidence/UNASSIGNED:Prognostic Level III.

Introduction/UNASSIGNED:Despite the recommendation for postoperative orthopedic follow-up after a hip fracture in elderly patients, many patients do not return for these visits. In this study, we attempt to determine if early follow-up (<4 weeks post-discharge) changes orthopedic post-operative management. Materials and Methods/UNASSIGNED:1232 patients aged > 55 years old who underwent operative fixation for hip fractures were enrolled into an orthopedic trauma registry and followed from hospitalization through one year. Demographics, comorbidities, injury severity, and hospital course data were collected. Need for readmission and orthopedic follow-up were ascertained through chart review. Results/UNASSIGNED:417 patients (33.8%) patients did not return for any follow-up and 30 (2.4%) patients died <30 days from discharge. 370 (45.5%) patients had early orthopedic follow-up ≤28 days after discharge. 317 (38.9%) patients were seen ≥29 days after discharge (late follow-up). 127 (15.6%) patients returned for isolated non-orthopedic care. There were 23 (6.2%) readmissions in the early group, 17 (5.4%) in the late group, and 24 (18.9%) in the no follow-up group (p < 0.001). Patients discharged home were more likely to present for early follow-up compared to those with late and non-orthopedic follow-up (p = 0.002), however there was no difference in readmission rates between those discharged home vs. SNFs/SARs. Discussion/UNASSIGNED:Patients who received isolated non-orthopedic follow-up within 4 weeks of surgery experienced more hospital readmissions than those with follow-up in that time period; however, these readmissions were primarily due to medical issues. There was no difference in orthopedic-related readmissions and changes in orthopedic management between groups. Patients discharged to SNFs/SARs did not present for early orthopedic as often as those discharged home. Conclusion/UNASSIGNED:Early orthopedic follow up after hip fracture care does not change post-operative management in these patients and has implications for value-based care. Level of Evidence/UNASSIGNED:Prognostic Level III.

Background/UNASSIGNED:Inaccuracy of ankle syndesmotic repair via reduction and trans-syndesmotic fixation can occur during ankle fracture repair. The goal of this study was to determine whether reduction and fixation of the posterior malleolar fracture (PM) fragment in rotational ankle fractures reduces the need for independent syndesmotic screw fixation. Methods/UNASSIGNED:A retrospective study was conducted using a consecutive series of patients treated operatively for a rotationally unstable ankle fracture with a PM fragment between 2011-2017. All ankle fractures underwent open reduction and internal fixation and divided into two groups: PM fixed or not fixed. An intraoperative stress evaluation of the ankle following bony fixation was performed in all cases to evaluate syndesmotic instability. Patient and fracture characteristics, and intraoperative instability and trans-syndesmotic fixation were compared between both groups. Results/UNASSIGNED:Eighty-five unstable ankle fractures that had a PM fragment were identified. Forty-three fractures underwent PM fixation and 42 did not. There were no differences between the PM fixation groups with regard to age, gender, body mass index or fracture pattern (p>0.183 for all). On average, PM fragments in the fixed group were larger than those not fixed (p<0.001). There were significantly lower odds of needing syndesmotic fixation if the PM fragment was reduced and fixed (p<0.001). Only 2 out of 43 ankles with a fixed PM fragment underwent syndesmotic fixation compared with 34 out of 42 non-fixed PM fragments. Conclusion/UNASSIGNED:.

BACKGROUND:The purpose of this study was to compare the long-term functional status of patients treated surgically for a clavicular nonunion using patients treated either op-eratively or non-operatively for an acute clavicle fracture as a comparison group. METHODS:Twenty consecutive patients treated by a single surgeon for a clavicle fracture nonunion were identified. For comparison of outcomes, acute clavicle fractures were identified from an electronic medical record (EMR) query of the same orthopedic surgeon. Ninety acute clavicle fracture patients were identified and 27 (30%) patients were available for long-term follow-up. Clavicular nonunions were compared to acute clavicle fracture patients in a univariate analysis then a multivariate analysis to analyze clavicle nonunion patients against operative and non-operative acute clavicle fracture patients. The main outcome measures were time to bony union, postoperative complications, visual analog scale (VAS) pain scores, and Short Musculoskeletal Functional Assessment (SMFA) scores at long-term follow-up. RESULTS:There was no difference in time to healing or functional outcomes as assessed by SMFA and VAS pain scores between clavicle nonunion and acute fracture patients. Postoperative complications also did not differ between the groups. CONCLUSIONS:Patients who are treated surgically for clavicular nonunions ultimately regain a similar functional status as patients who are treated either operatively or non-operatively for an acute clavicle fracture and heal acutely.

Background/UNASSIGNED:Orthopedic surgeons use radiographs to determine degrees of fracture healing, guide progression of clinical care, and assist in determining weight bearing and removal of immobilization. However, no gold standard exists to determine the progression of healing of humeral shaft fractures treated non-operatively. Purpose/UNASSIGNED:The purpose of this study was to determine whether a scale comparable to the modified Radiographic Union Score for Tibial (RUST) fractures applied to non-operatively treated humeral shaft fractures can increase interobserver reliability in determining fracture healing. Methods/UNASSIGNED:A retrospective review was undertaken by three orthopedic traumatologists and one musculoskeletal radiologist, who evaluated 50 sets of anteroposterior and lateral radiographs, presented at random, of non-operatively treated humeral shaft fractures at various stages of healing from 17 patients. The radiographs were scored using a modified RUST scale called the Radiographic Humerus Union Measurement (RHUM). Observers were blinded to the time from injury. After a 4-week washout period, observers again scored the same radiographs. Observers classified each fracture as either healed or not healed based on the combination of radiographs. Inter- and intraobserver reliability of the RHUM were determined using an intraclass correlation coefficient (ICC). Interobserver reliability of determining a healed fracture was calculated using Cohen's kappa (κ) statistics. A receiver operator characteristic curve was conducted to determine the RHUM score predictive of a fracture being considered healed. Results/UNASSIGNED:ICC demonstrated almost perfect interobserver reliability (ICC, 0.838; ICC 95% CI, 0.765 to 0.896) and intraobserver reliability (ICC range, 0.822 to 0.948) of the RHUM. κ demonstrated substantial agreement between observers in considering a fracture healed (κ = 0.647). Receiver operating characteristic (ROC) curve demonstrated that a RHUM of 10 or higher is an excellent predictor of the observer considering the fracture healed (area under the ROC curve = 0.946, specificity = 0.957, 95% CI specificity, 0.916 to 0.979). Conclusions/UNASSIGNED:This cortical scoring system has excellent interobserver reliability in humeral shaft fractures treated non-operatively. Consistent with previous cortical scoring systems, a RHUM score of 10 or above can be considered radiographically healed.
