Preventing Fragility Fractures: A 3-Month Critical Window of Opportunity.

INTRODUCTION: Low-energy falls are the leading cause of injury-related morbidity and mortality in the elderly. In the past, physicians focused on treating fractures resulting from falls rather than preventing them. The purpose of this study is to identify patients with a hospital encounter for fall prior to a fracture as an opportunity for pre-injury intervention when patients might be motivated to engage in falls prevention. MATERIALS & METHODS: A retrospective analysis of all emergency room and inpatient encounters in 2016 with an ICD10 diagnosis code including "fall" across a tri-state health system was performed. Subsequent encounters with diagnosis of fracture within 2 years were then identified. Data was collected for time to subsequent fracture, fracture type and location, and length of stay of initial encounter. RESULTS: There were 12,382 encounters for falls among 10,589 patients. Of those patients, 1,040 (9.8%) sustained a subsequent fracture. Fractures were most commonly lower extremity fractures (661 fractures; 63.5%), including hip fractures (447 fractures; 45.87%). Median time from fall to fracture was 105 days (IQR 16-359 days). DISCUSSION: Falls are an important, modifiable risk factor for fragility fracture. This study demonstrates that patients are presenting to the hospital with one of the main modifiable risk factors for fracture within a time window that allows for intervention. CONCLUSIONS: Presentation to the hospital for a fall is a vital opportunity to intervene and prevent subsequent fracture in a high-risk population.

Minimal Clinically Important Difference After Carpal Tunnel Release Using the PROMIS Platform.

PURPOSE: In light of recently-proposed quality measures for carpal tunnel release (CTR), elucidating the minimal clinically important difference (MCID) for selected outcome measures will be important when interpreting treatment responses. Our purpose was to estimate the MCID of the Patient-Reported Outcomes Measurement Information System (PROMIS) instruments and the short Disabilities of the Arm, Shoulder, and Hand (QuickDASH) following CTR. METHODS: Adult patients undergoing isolated unilateral CTR between July 2014 and October 2016 were identified. Outcomes included the PROMIS Upper Extremity (UE) Computer Adaptive Test (CAT), Physical Function (PF) CAT, QuickDASH, and Pain Interference (PI) CAT. For inclusion, pretreatment baseline (within 60 days of surgery) and postoperative (6-90 days) UE or PF CAT scores were required, as well as a response on a 5-point Likert scale to the question "How much relief and/or improvement do you feel you have experienced as a result of your treatment?" The MCID was calculated using SD and minimum detectable change (MDC) distribution methods. RESULTS: In response to the Likert scale question, 88.6% of patients reported improvement at a mean of 14.8 days after surgery. The infrequency of patients reporting no change (5 of 44; 11.4%) precluded calculation of a statistically sound anchor-based MCID value. The MCID values, as calculated using the one-half SD method, were 3.6, 4.6, 10.4, and 3.4 for the UE CAT, PF CAT, QuickDASH, and PI CAT, respectively. CONCLUSIONS: We have calculated MCID values for the UE CAT, PF CAT, QuickDASH, and PI CAT for patients undergoing CTR. Although the small number of patients reporting no change and minimal change after surgery precluded an anchor-based MCID calculation, we report estimates using the one-half SD method for the MCID following CTR. CLINICAL RELEVANCE: These MCID estimates will be helpful when interpreting CTR clinical outcomes and for powering prospective trials.

Unstable Pelvic Ring Injuries: How Soon Can Patients Safely Bear Weight?

OBJECTIVE: To determine if time to weight bearing (WB) is associated with complications in operatively treated pelvic ring injuries. DESIGN: Retrospective cohort study. SETTING: Academic Level I trauma hospital. PATIENTS: Two hundred eighty-six patients with pelvic ring injuries treated operatively over a 10-year period [OTA/AO 61-B1-3, 61-C1-3; Young-Burgess lateral compression (LC) 1-3, anterior-posterior compression (APC) 1-3, and vertical shear] were included. INTERVENTION: Patients were stratified into early (≤8 weeks) and late (>8 weeks) time to full WB groups. MAIN OUTCOME MEASURE: Composite outcome of implant failure [broken screw(s)/plate(s), screw(s) loosening], revision surgery, and malunion. RESULTS: We identified 286 patients with a mean age of 39.9 years (range: 18-81 years) and an average follow-up of 1.2 years (1.0-9 years). There were 132 and 154 patients in the early and late WB groups, respectively. A total of 142 Young-Burgess LC-1, 48 LC-2, 23 LC-3, 10 APC-1, 45 APC-2, 8 APC-3, and 8 vertical shear injuries were noted. Complications were noted in 47 patients (16%). Complications included 18 implant failures, 16 malunions, and 13 patients who required revision operations for loss of reduction. Time to WB was not associated with composite complication rates (P = 0.24). APC-2, LC-3, and injuries with bilateral rami fractures were noted to have a higher complication rates independent of time to WB (P = 0.005, 0.03, and 0.03, respectively). CONCLUSIONS: No difference in implant failure, malunion, or early loss of reduction between operatively treated pelvic ring injuries allowed to WB as tolerated before 8 weeks compared with those who remained on protected WB protocol for any time greater than 8 weeks was noted. These data may provide information to support early WB protocols. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Cost Implications of Varying the Surgical Technique, Surgical Setting, and Anesthesia Type for Carpal Tunnel Release Surgery.

PURPOSE: Carpal tunnel release (CTR) is a common surgical procedure, representing a financial burden to the health care system. The purpose of this study was to test whether the choice of CTR technique (open carpal tunnel release [OCTR] vs endoscopic carpal tunnel release [ECTR]), surgical setting (operating room vs procedure room [PR]), and anesthetic type (local, monitored anesthesia care [MAC], Bier block, general) affected costs or payments. METHODS: Consecutive adult patients undergoing isolated unilateral CTR between July 2014, and October 2017, at a single academic medical center were identified. Patients undergoing ECTR converted to OCTR, revision surgery, or additional procedures were excluded. Using our institution's information technology value tools, we calculated total direct costs (TDCs), total combined payment (TCP), hospital payment, surgeon payment, and anesthesia payment for each surgical encounter. Cost data were normalized using each participant's surgical encounter cost divided by the average cost in the data set and compared across 8 groups (defined by surgery type, operation location, and anesthesia type). RESULTS: Of 479 included patients, the mean age was 55.3 ± 16.1 years, and 68% were female. Payer mix included commercial (45%), Medicare (37%), Medicaid (13%), workers' compensation (2%), self-pay (1%), and other (3%) insurance types. The TDC and TCP both differed significantly between each CTR group, and OCTR in the PR under local anesthesia was the lowest. The OCTR/local/operating room, OCTR/MAC/operating room, and ECTR/operating room, were associated with 6.3-fold, 11.0-fold, and 12.4-16.6-fold greater TDC than OCTR/local/PR, respectively. CONCLUSIONS: Performing OCTR under local anesthetic in the PR setting significantly minimizes direct surgical encounter costs relative to other surgical methods (ECTR), anesthetic methods (Bier block, MAC, general), and surgical settings (operating room). CLINICAL RELEVANCE: This study identifies modifiable factors that may lead to cost reductions for CTR surgery.

Obesity Is Associated With High Perioperative Complications Among Surgically Treated Intertrochanteric Fracture of the Femur.

OBJECTIVES: To document the complications among obese patients who underwent surgical fixation for intertrochanteric femur (IT) fractures and to compare with nonobese patients. DESIGN: Retrospective cohort study. SETTING: Four level I trauma centers. PATIENTS: 1078 IT fracture patients. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Patient and fracture characteristics, surgical duration, surgical delay intraoperative and postoperative complications, inpatient mortality, and length of stay. METHOD: A retrospective review at 4 academic level I trauma centers was conducted to identify skeletally mature patients who underwent surgical fixation of intertrochanteric fractures between June 2008 and December 2014. Descriptive data, injury characteristics, OTA fracture classification, and associated medical comorbidities were documented. The outcomes measured included in-hospital complications, length of stay, rate of blood transfusion, change in hemoglobin levels, operative time, and wound infection. RESULTS: Of 1078 unique patients who were treated for an IT fracture, 257 patients had a Body mass index (BMI) of 30 or greater. Patients with a high BMI (≥30) had a significantly lower mean age (73 vs. 77 years, P < 0.0001), higher percentage of high-energy injuries (18% vs. 9%, P = 0.0004), greater mean duration of surgery (96 vs. 86 minutes, P = 0.02), and higher mean length of stay (6.5 vs. 5.9 days, P = 0.004). The high-BMI group (n = 257) had significantly higher percentages of patients with complications overall (43% vs. 28%, P < 0.0001), respiratory complications (11% vs. 3%, P < 0.0001), electrolyte abnormalities (4% vs. 2%, P = 0.01), and sepsis (4% vs. 1%, P = 0.002). Patients with BMI ≥ 40 had a much higher rate of respiratory complications (18%) and wound complications (5%) than obese (BMI: 30-39.9) and nonobese patients (BMI < 30). CONCLUSION: Intertrochanteric hip fracture patients with a BMI of >30 kg/m are much more likely to sustain systemic complications including respiratory complications, electrolyte abnormalities, and sepsis. In addition, morbidly obese patients are more likely to sustain respiratory complications and wound infections than obese (BMI: 30-39.9 kg/m) and nonobese patients (BMI: < 30 kg/m). The findings from this study can help direct surgeons in the counseling to obese patients and their family, and perhaps increase hospital reimbursement for this group of patients. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

The Role of Radiographs and Office Visits in the Follow-Up of Healed Intertrochanteric Hip Fractures: An Economic Analysis.

OBJECTIVES: The purpose of this study was to evaluate the role and the necessity of radiographs and office visits obtained during follow-up of intertrochanteric hip injuries. DESIGN: Retrospective study. SETTING: Two level I trauma centers. PATIENTS: Four hundred sixty-five elderly patients who were surgically treated for an intertrochanteric fracture of the femur at 2 level I trauma centers between January 2009 and August 2014 were retrospectively identified from orthopaedic trauma databases. INTERVENTION: Analysis of all healed intertrochanteric hip fractures, including demographic characteristics, quality of reduction, time of healing, number of office visits, number of radiographs obtained, and each radiograph for fracture alignment, implant position or any pathological changes. RESULTS: The surgical fixation of 465 fractures included 155 short nails (33%), 232 long nails (50%), 69 sliding hip screw devices (15%), 7 trochanteric stabilizing plates (1.5%), and 2 proximal femur locking plates (0.5%). The average fracture healing time was 12.8 weeks and the average follow-up was 81.2 weeks. Radiographs of any patient obtained after the fracture had healed did not reveal any changes, including fracture alignment or implant position and hardware failure. In 9 patients, pathological changes, including arthritis (3), avascular necrosis (3), and ectopic ossification (3) were noted. The average number of elective office visits and radiographs obtained after the fracture had healed were 2.8 (range: 1-8) and 2.6 (range: 1-8), respectively. According to Medicare payments to the institution, these radiographs and office visits account for a direct cost of $360.81 and $192, respectively, per patient. CONCLUSION: The current study strongly suggests that there is a negligible role for radiographs and office visits during the follow-up of a well-healed hip fracture when there is documented evidence of radiographic and clinical healing with acceptable fracture alignment and implant position. Implementation of this simple measure will help in reducing the cost of care and inconvenience to elderly patients. LEVEL OF EVIDENCE: Diagnostic Level IV.

Postoperative opioid analgesic use after Nuss versus Ravitch pectus excavatum repair.

BACKGROUND/PURPOSE: Anticipated postoperative pain may affect procedure choice in patients with pectus excavatum. This study aims to compare postoperative pain in patients undergoing Nuss and Ravitch procedures. METHODS: A 5year retrospective review was performed. Data on age, gender, Haller index, procedure, pain scores, pain medications, and length of hospital stay were collected. Total inpatient opioid administration was converted to morphine equivalent daily dose per kilogram (MEDD/kg) and compared between procedures. RESULTS: One hundred eighty-one patients underwent 125 (69%) Nuss and 56 (31%) Ravitch procedures. Ravitch patients were older (15.7 yo vs 14.6 yo, p=0.004) and had a higher Haller index (5.21 vs 4.10, p=<0.001). Nuss patients had higher average daily pain scores, received 25% more opioids (MEDD/kg 0.66 vs. 0.49, p=<0.001), and received twice as much IV diazepam/kg. In the multivariate analysis, higher MEDD/kg correlated with both the Nuss procedure and older age in the Nuss group. Opioid administration did not correlate with Haller index or Nuss bar fixation technique. Increased NSAID administration did not correlate with lower use of opioids. CONCLUSION: The Nuss procedure is associated with greater postoperative pain compared to the Ravitch procedure. Opioid use is higher in older patients undergoing the Nuss procedure, but is not associated with severity of deformity.
