RÉSUMÉ
This paper focuses on recent advances in research on strategies that support self-control in everyday life. No one strategy or set of strategies appears to be effective at all times and in all situations. To understand effective self-control, we must expand our understanding of how strategies fit the situation and the person. To this end, we propose researching unexplored aspects of situations, how self-control strategies develop in the first place, and the role of emotion regulation in self-control strategy effectiveness. We also highlight methodological blind spots and offer ways to correct them and introduce new methodological approaches to best capture self-control strategies in everyday life.

INTRODUCTION: Distal femur fractures (DFFs) are associated with high complication and mortality rates in the elderly. Using the National Inpatient Sample and Medicare data, we describe trends in the incidence of DFFs by fixation type and associated healthcare costs. METHODS: Annual population rates and volume of inpatient DFFs were estimated using Poisson regression with the US Census as a denominator. We used Current Procedural Terminology codes in Medicare patients to determine episode-of-care cost by treatment, classified as intramedullary nail, open reduction and internal fixation, and distal femur arthroplasty (DFR). RESULTS: The annual incidence of DFFs in the United States is approximately 27.4 per 100,000. Admission for DFFs increased from 2002 to 2020, with the highest volume and rate in those aged 85 years and older. DFF incidence increased (1.95×) from 142 per 1 million (95% CI: 140 to 144) in 2006 to 281 per 1 million (95% CI: 278-284) in 2019. From 2012 to 2019, the percentage of DFFs treated by intramedullary nail increased from 6.8% to 8.4%, open reduction and internal fixation decreased from 89.9% to 76.6%, and DFR increased from 3.3% to 14.9%. DFR cost was significantly greater than other treatment choices across all years for initial inpatient admission costs and 90-day episode-of-care costs (all P < 0.0001). CONCLUSION: DFF volume has increased in the past 20 years, predominantly in elderly patients. Greater than 4.5× increase was observed in the proportion of geriatric DFFs treated with DFR during this study period. The total cost of DFR treatment was consistently greater than other surgical treatments.
RÉSUMÉ
Background: Dual plating of the distal femur is indicated for the treatment of complex intra-articular fractures, supracondylar femoral fractures, low periprosthetic fractures, and nonunions. The aim of this procedure is anatomical alignment of the articular surface, restoration of the articular block, and prevention of varus collapse. Description: Following preoperative planning, the patient is positioned supine with the knee flexed at 30°. The lateral incision is made first, with a mid-lateral incision that is in line with the femoral shaft. If intra-articular work is needed this incision can be extended by curving anteriorly over the lateral femoral condyle. Next, the iliotibial band is transected in line with its fibers. The vastus lateralis fascia is incised and elevated off the septum, working distal to proximal. Care should be taken to maintain hemostasis when encountering femoral artery perforating vessels. Once there is adequate exposure, several reduction aids can be utilized, including a bump under the knee, Schanz pins, Kirschner wires, and reduction clamps. A lateral precontoured plate is placed submuscularly, and the most proximal holes are filled percutaneously. The medial incision begins distally at the adductor tubercle and is a straight incision made proximally in line with the femoral shaft. The underlying fascia is transected in line with the skin incision, and the vastus medialis is elevated. Care should be taken to avoid the descending geniculate artery, as well as its articular branch and the muscular branch to the vastus medialis. A lateral tibial plateau plate is contoured and placed. Alternatives: Nonoperative treatment of distal femoral fractures is rare, but relative indications for nonoperative treatment include frailty of the patient, lack of ambulatory status, a non-reconstructible fracture, or a stable fracture. These patients are placed in a long-leg cast followed by a hinged knee brace1. There are several other surgical fixation options, including lateral plating, retrograde intramedullary nailing, distal femoral replacement, and augmentation of a retrograde nail with a plate. Rationale: Dual plating has several benefits, depending on the clinical scenario. Biomechanical studies have found that dual plating results in increased stiffness and construct strength2,3. Additional construct stability can be offered through the use of locking plates, particularly in osteoporotic bone. Taken together, this increased stability and construct strength can allow for earlier weight-bearing, which is particularly important for fractures in the geriatric population. Furthermore, the increased stiffness and construct strength make this procedure a favorable treatment option for nonunion, and it has been shown to result in lower rates of postoperative nonunion compared with lateral plating alone4-7. Adjunctive use of a medial plate also has been suggested to prevent varus collapse, particularly with metaphyseal comminution and poor bone quality2,3,8. Finally, in the periprosthetic fracture population, dual plating also removes the concern of incompatibility with a retrograde nail. Expected Outcomes: The outcomes of dual plating are promising, given the severity of the injury. When comparing operative to nonoperative treatment outcomes, nonoperatively managed patients had worse functional outcomes and higher rates of complications related to immobility1. Dual plating of supracondylar fractures and intra-articular distal femoral fractures yields nonunion rates ranging from 0% to 12.5%, lower than the 18% to 20% reported with lateral locking plates4-7,9-12. This reduction in nonunions has been shown to lead to fewer revisions when compared with single-plating techniques7. In prior studies, 95% of nonunions treated with the dual-plating technique achieved union postoperatively11. One concern when utilizing the medial approach is critical damage to medial vascularity; however, this result has not been reported in the literature, and there is a safe operating window13. Despite the benefits of dual plating, there are relatively high rates of infection following dual plating (0% to 16.7%) compared with lateral plating alone (3.6% to 8.5%)5,14-17. However, many of these studies are small case series, highlighting that a surgeon's comfort and skill with these procedures is paramount to patient outcomes. Important Tips: Meticulous placement and contouring of lateral and medial plates are required to prevent malreduction of the articular block that creates a "golf-club deformity."18,19During the medial approach, be aware of descending geniculate artery-particularly its muscular branch, which is â¼5 cm from the adductor tubercle/medial epicondyle, and its root, which enters the compartment at the adductor hiatus at â¼16 cm13.
RÉSUMÉ
OBJECTIVES: This study compared the maximal compression force before thread stripping of the novel bone-screw-fastener (BSF) with the traditional buttress screw (TBS) in synthetic osteoporotic and cadaveric bone models. METHODS: The maximum compression force of the plate-bone interface before loss of screw purchase during screw tightening was measured between self-tapping 3.5-mm BSF and 3.5-mm TBS using calibrated load cells. Three synthetic biomechanical models were used: a synthetic osteoporotic diaphysis (model 1), a 3-layer biomechanical polyurethane foam with 50-10-50 pounds-per-cubic-foot layering (model 2), and a 3-layer polyurethane foam with 50-15-50 pounds-per-cubic-foot layering (model 3). For the cadaveric metaphyseal model, 3 sets of cadaveric tibial plafonds and 3 sets of cadaveric tibial plateaus were used. A plate with sensors between the bone and plate interface was used to measure compression force during screw tightening in the synthetic bone models, while an annular load cell that measured screw compression as it slid through a guide was used to measure compression in the cadaver models. RESULTS: Across all synthetic osteoporotic bone models, the BSF demonstrated greater maximal compression force before stripping compared with the TBS [model 1, 155.51 N (SD = 7.77 N) versus 138.78 N (SD = 12.74 N), P = 0.036; model 2, 218.14 N (SD = 14.15 N) versus 110.23 N (SD = 8.00 N), P < 0.001; model 3, 382.72 N (SD = 20.15) versus 341.09 N (SD = 15.57 N), P = 0.003]. The BSF had greater maximal compression force for the overall cadaver trials, the tibial plafond trials, and the tibial plateau trials [overall, 111.27 N vs. 97.54 N (SD 32.32 N), P = 0.002; plafond, 149.6 N versus 132.92 N (SD 31.32 N), P = 0.006; plateau, 81.33 N versus 69.89 N (SD 33.38 N), P = 0.03]. CONCLUSIONS: The novel bone-screw-fastener generated 11%-65% greater maximal compression force than the TBS in synthetic osteoporotic and cadaveric metaphyseal bone models. A greater compression force may increase construct stability, facilitate early weight-bearing, and reduce construct failure.

Tibial plateau fractures are caused by high-energy or low-energy trauma and result in complex injuries that require careful management of both osseous injuries and associated soft tissues. The posterior aspect of the tibial plateau can be involved in a variety of fracture patterns, requiring systematic evaluation, imaging, and advanced surgical planning to address these complex injuries. Early classification systems failed to classify posterior plateau fractures; however, three-dimensional imaging and newer classification schemes, including the Quadrant System and 3D systems, have incorporated posterior column lesions. There has been a growing body of literature focused on fixation principles and plating options for posterior column fractures. Furthermore, there are multiple approaches for surgeons to choose between, including a direct posterior, posteromedial, posterolateral (including Lobenhoffer and lateral condyle osteotomy), and combined posterior approach. This article presents a guide for managing posterior tibial plateau fractures, including the initial evaluation and management, descriptions of the surgical approaches, principles of fixation, and the associated outcomes and complications.
RÉSUMÉ
BACKGROUND: Previous arthroplasty utilization research predominantly examined Black and White populations within the US. This is the first known study to examine utilization and complications in poorly studied minority racial groups such as Asians and Native Hawaiian/Pacific-Islanders (NHPI) as compared to Whites. RESULTS: Data from 3304 primary total hip and knee arthroplasty patients (2011 to 2019) were retrospectively collected, involving 1789 Asians (52.2%), 1164 Whites (34%) and 320 Native Hawaiians/Pacific Islanders (NHPI) (9.3%). The 2012 arthroplasty utilization rates for Asian, White, and NHPI increased by 32.5%, 11.2%, and 86.5%, respectively, by 2019. Compared to Asians, Whites more often underwent hip arthroplasty compared to knee arthroplasty (odds ratio (OR) 1.755; p < 0.001). Compared to Asians, Whites and NHPI more often received total knee compared to unicompartmental knee arthroplasty (White: OR 1.499; NHPI: OR 2.013; p < 0.001). White patients had longer hospitalizations (2.66 days) compared to Asians (2.19 days) (p = 0.005) following bilateral procedures. Medicare was the most common insurance for Asians (66.2%) and Whites (54.2%) while private insurance was most common for NHPI (49.4%). Compared to Asians, economic status was higher for Whites (White OR 0.695; p < 0.001) but lower for NHPI (OR 1.456; p < 0.001). After controlling for bilateral procedures, NHPI had a lower risk of transfusion compared to Asians (OR 0.478; p < 0.001) and Whites had increased risk of wound or systemic complications compared to Asians (OR 2.086; p = 0.045). CONCLUSIONS: Despite NHPI demonstrating a significantly poorer health profile and lower socioeconomic status, contrary to previous literature involving minority racial groups, no significant overall differences in arthroplasty utilization rates or perioperative complications could be demonstrated amongst the racial groups examined.

OBJECTIVES: To assess trends in Patient-Reported Outcome Measurement Information Systems (PROMIS) Physical Function (PF) and Pain Interference (PI) in surgically treated tibial shaft fracture patients progressing to union versus nonunion. DESIGN: Retrospective cohort study. SETTING: Level 1 trauma center. PATIENT SELECTION CRITERIA: Patients with operatively treated tibial shaft fractures (AO/OTA 42-A, B, C) using an intramedullary nail. OUTCOME MEASURES AND COMPARISONS: PROMIS PF and PI were compared between patients progressing to union and patients requiring nonunion repair. RESULTS: A total of 234 patients (196 union, 38 nonunion) were included consisting 144 men and 90 women. The mean age of included patients was 40.8 years. A significant difference in mean PROMIS PF between union and nonunion patients was observed at 1-3 months ( P = 0.005), 3-6 months ( P < 0.001), 6-9 months ( P = 0.003), and 6-12 months ( P = 0.018). The odds of developing nonunion for every unit decrease in PROMIS PF was significant at 3-6 months (OR 1.07, P = 0.028) and 6-9 months (OR 1.17, P = 0.015). A significant difference in mean PROMIS PI between union and nonunion patients was observed at 1-3 months ( P = 0.001), 3-6 months ( P = 0.005), and 6-9 months ( P = 0.005). The odds of developing nonunion for every unit increase in PROMIS PI was significant at 1-3 months (OR 1.11, P = 0.005), 3-6 months (OR 1.10, P = 0.011), and 6-9 months (OR 1.23, P = 0.011). CONCLUSIONS: Poorly trending PROMIS PF and PI in the clinical setting is a factor that can be used to evaluate progression to nonunion following tibial shaft repair where imaging studies may lag behind.

OBJECTIVES: To determine the postoperative trajectory and recovery of patients who undergo Lisfranc open reduction and internal fixation using Patient-Reported Outcomes Measurement Information System (PROMIS) physical function (PF) and pain interference (PI). DESIGN: Retrospective cohort study. SETTING: Level 1 trauma center. PATIENT SELECTION CRITERIA: Patients who underwent Lisfranc open reduction and internal fixation between January 2002 and December 2022 with documented PROMIS PF and/or PI scores after surgery. OUTCOME MEASURES AND COMPARISONS: PROMIS PF and PI were mapped over time up to 1 year after surgery. A subanalysis was performed to compare recovery trajectories between high-energy and low-energy injuries. RESULTS: A total of 182 patients were included with average age of 38.7 (SD 15.9) years (59 high-energy and 122 low-energy injuries). PROMIS PF scores at 0, 6, 12, 24, and 48 weeks were 30.2, 31.4, 39.2, 43.9, and 46.7, respectively. There was significant improvement in PROMIS PF between 6 and 12 weeks ( P < 0.001), 12-24 weeks ( P < 0.001), and 24-48 weeks ( P = 0.022). A significant difference in PROMIS PF between high and low-energy injuries was seen at 0 week (28.4 vs. 31.4, P = 0.010). PROMIS PI scores at 0, 6, 12, 24, and 48 weeks were 62.2, 58.5, 56.6, 55.7, and 55.6, respectively. There was significant improvement in PROMIS PI 0-6 weeks ( P = 0.016). A significant difference in PROMIS PI between high-energy and low-energy injuries was seen at 48 weeks with scores of (58.6 vs. 54.2, P = 0.044). CONCLUSIONS: After Lisfranc open reduction and internal fixation, patients can expect improvement in PF up to 1 year after surgery, with the biggest improvement in PROMIS PF scores between 6 and 12 weeks and PROMIS PI scores between 0 and 6 weeks after surgery. Regardless the energy type, Lisfranc injuries seem to regain comparable PF by 6-12 months after surgery. However, patients with higher energy Lisfranc injuries should be counseled that these injuries may lead to worse PI at 1 year after surgery as compared with lower energy injuries. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

BACKGROUND: Despite increasing attention, disparities in outcomes for Black and Hispanic patients undergoing orthopedic surgery are widening. In other racial-ethnic minority groups, outcomes often go unreported. We sought to quantify disparities in surgical outcomes among Asian, American Indian or Alaskan Native, and Native Hawaiian or Pacific Islander patients across multiple orthopedic subspecialties. MATERIALS AND METHODS: The National Surgical Quality Improvement Program was queried to identify all surgical procedures performed by an orthopedic surgeon from 2014 to 2020. Multivariable logistic regression models were used to investigate the impact of race and ethnicity on 30-day medical complications, readmission, reoperation, and mortality, while adjusting for orthopedic subspecialty and patient characteristics. RESULTS: Across 1,512,480 orthopedic procedures, all patients who were not White were less likely to have arthroplasty-related procedures (P<.001), and Hispanic, Asian, and American Indian or Alaskan Native patients were more likely to have trauma-related procedures (P<.001). American Indian or Alaskan Native (adjusted odds ratio [AOR], 1.005; 95% CI, 1.001-1.009; P=.011) and Native Hawaiian or Pacific Islander (AOR, 1.009; 95% CI, 1.005-1.014; P<.001) patients had higher odds of major medical complications compared with White patients. American Indian or Alaskan Native patients had higher risk of reoperation (AOR, 1.005; 95% CI, 1.002-1.008; P=.002) and Native Hawaiian or Pacific Islander patients had higher odds of mortality (AOR, 1.003; 95% CI, 1.000-1.005; P=.019) compared with White patients. CONCLUSION: Disparities regarding surgical outcome and utilization rates persist across orthopedic surgery. American Indian or Alaskan Native and Native Hawaiian or Pacific Islander patients, who are under-represented in research, have lower rates of arthroplasty but higher odds of medical complication, reoperation, and mortality. This study highlights the importance of including these patients in orthopedic research to affect policy-related discussions. [Orthopedics. 2024;47(3):e131-e138.].

INTRODUCTION: Understanding minimal clinically important differences (MCID) in patient reported outcome measurement are important in improving patient care. The purpose of this study was to determine the MCID of Patient-Reported Outcome Measurement System (PROMIS) Physical Function (PF) domain for patients who underwent operative fixation of a tibial plateau fracture. METHODS: All patients with tibial plateau fractures that underwent operative fixation at a single level 1 trauma center were identified by Current Procedural Terminology codes. Patients without PROMIS PF scores or an anchor question at two-time points postoperatively were excluded. Anchor-based and distribution-based MCIDs were calculated. RESULTS: The MCID for PROMIS PF scores was 4.85 in the distribution-based method and 3.93 (SD 14.01) in the anchor-based method. There was significantly more improvement in the score from the first postoperative score (<7 weeks) to the second postoperative time (<78 weeks) in the improvement group 10.95 (SD 9.95) compared to the no improvement group 7.02 (SD 9.87) in the anchor-based method (P < 0.001). The percentage of patients achieving MCID at 7 weeks, 3 months, 6 months, and 1 year were 37-42 %, 57-62 %, 80-84 %, and 95-87 %, respectively. DISCUSSION: This study identified MCID values for PROMIS PF scores in the tibial plateau fracture population. Both MCID scores were similar, resulting in a reliable value for future studies and clinical decision-making. An MCID of 3.93 to 4.85 can be used as a clinical and investigative standard for patients with operative tibial plateau fractures.

INTRODUCTION: This study described a deformity induced by medial plating of supracondylar distal femur fractures using plates that are precontoured for other anatomic locations. MATERIALS AND METHODS: OTA/AO 33A fractures were created in 12 sawbone femurs and fixed with either a proximal humerus locking plate (PH), an ipsilateral lateral tibial plateau plate (LTP), or an ipsilateral medial distal tibial plate (MDT). A motion capture system measured changes in length and rotation of the distal femur as the plate was applied. Each plate underwent four trials and the mean and standard deviation (SD) for each measurement was reported. An analysis of variance with post hoc Tukey test compared malreduction measures between plate types. RESULTS: All plates consistently created a varus deformity. There was lateral lengthening with a compensatory medial shortening and an increase in the lateral distal femoral angle. The distal fracture fragment was laterally translated, and internally rotated. The PH plate had significantly greater lateral length (27.39 mm SD 4.78, p = 0.007), shorter medial length (13.57 mm SD 4.99, p = 0.028), greater lateral translation (28.82 mm SD 5.70, p = 0.010) and greater widening of the lateral distal femoral angle (28.54° SD 4.98, p < 0.001) than the LTP and MDT plates. The MDT plate had significantly greater angulation anteriorly (8.40° SD 1.07, p < 0.001) and laterally (7.63° SD 3.10, p = 0.002) than the PH and LTP plates. There was no significant difference between plates in internal rotation (PH: 3.07° SD 2.79; LTP: 2.05° SD 1.05; MDT 3.81° SD 3.56; p = 0.659). CONCLUSION: When dual plating supracondylar distal femur fractures, poor plate positioning and a mismatch between plate contour and the slope of the medial distal femur can lead to varus angulation, internal rotation, and lateral translation or a "reverse golf club deformity". After comparing three types of precontoured plates, the authors recommend initial evaluation of the ipsilateral proximal tibial plate when placing a plate along the medial distal femur.

BACKGROUND: Postoperative acute kidney injury (AKI) is a critical issue in geriatric patients with pre-existing chronic kidney disease (CKD) undergoing orthopedic trauma surgery. The goal of this study was to investigate modifiable intraoperative risk factors for AKI. METHODS: A retrospective study was conducted on 206 geriatric patients with CKD, who underwent orthopedic trauma surgery. Several variables, including intraoperative blood loss, postoperative hypoalbuminemia, intraoperative blood pressure and long-term use of potentially nephrotoxic drugs, were analyzed. RESULTS: Postoperative AKI (KIDGO) was observed in 25.2% of the patients. The 1-year mortality rate increased significantly from 26.7% to 30.8% in patients who developed AKI. Primary risk factors for AKI were blood loss (p < 0.001), postoperative hypoalbuminemia (p = 0.050), and potentially nephrotoxic drugs prior to admission (angiotensin-converting enzyme inhibitors, angiotensin-II receptor antagonists, diuretics, antibiotics, NSAIDs) (p = 0.003). Furthermore, the AKI stage negatively correlated with propofol dose per body weight (p = 0.001) and there was a significant association between AKI and the use of cement (p = 0.027). No significant association between intraoperative hypotension and AKI was observed in any statistical test. Femur fracture surgeries showed the greatest blood loss (524mL ± 357mL, p = 0.005), particularly intramedullary nailing at the proximal femur (598mL ± 395mL) and revision surgery (769mL ± 436mL). CONCLUSION: In geriatric trauma patients with pre-existing CKD, intraoperative blood loss, postoperative hypoalbuminemia, and pre-admission use of potentially nephrotoxic drugs are associated with postoperative AKI. The findings highlight the necessity to mitigate intraoperative blood loss and promote ortho-geriatric co-management to reduce the incidence and subsequent mortality in this high-risk population.

Anterior cruciate ligament tears or ruptures are common orthopedic injuries. Anterior cruciate ligament reconstruction (ACLR) is an orthopedic procedure allowing for earlier return to sports, improved maintenance of lifestyle demands, and restored knee stability and kinematics. A perioperative rehabilitative adjunct recently gaining interest is blood flow restriction (BFR), a method in which temporary restriction of blood flow to a chosen extremity is introduced and can be used as early as a few days postoperative. There has been increasing investigation and recent literature regarding BFR. This review synthesizes current concepts of BFR use in the ACLR perioperative period.

PURPOSE: Patient-reported minimal clinically important differences (MCID) provide a standard to compare clinical outcomes. The purpose of this study was to calculate the MCID of PROMIS Physical Function (PF), Pain Interference (PI), Anxiety (AX), and Depression (DEP) scores in patients with pelvis and/or acetabular fractures. METHODS: All patients with operatively treated pelvic and/or acetabular fractures were identified. Patients were categorized as either only pelvis and/or acetabular fractures (PA) or polytrauma (PT). PROMIS PF, PI, AX, and DEP scores were evaluated at 3-month, 6-month, and 12-month intervals. Distribution-based MCID and anchor-based MCID were calculated for the overall cohort, PA, and PT groups. RESULTS: The overall distribution-based MCIDs were PF (5.19), PI (3.97), AX (4.33), and DEP (4.41). The overall anchor-based MCIDs were PF (7.18), PI (8.03), AX (5.85), DEP (5.00). The percentage of patients achieving MCID for AX was 39.8-54% at 3 months and 32.7-56% at 12 months. The percentage of patients achieving MCID for DEP was 35.7-39.3% at 3 months and 32.1-35.7% at 12 months. The PT group had worse PROMIS PF scores than the PA group at all time points [post-operative, 3-month, 6-month, and 12-month scores, (28.3 (6.3) vs. 26.8 (6.8) P = 0.016), (38.1 (9.2) vs. 35.0 (8.7) P = 0.037), (42.8 (8.2) vs. 39 (9.6) P = 0.015), (46.2 (9.7) vs. 41.2 (9.7) P = 0.011)]. CONCLUSION: An overall MCID for PROMIS PF was 5.19-7.18, PROMIS PI 3.97-8.03, PROMIS AX of 4.33-5.85, and PROMIS DEP of 4.41-5.00. The PT group had worse PROMIS PF at all time points. The percentage of patients achieving MCID for AX and DEP plateaued at 3 months post-operatively. LEVEL OF EVIDENCE: Level IV.
RÉSUMÉ
OBJECTIVE: To calculate the minimal clinically important differences (MCIDs) of patient-reported outcomes measurement information system physical function (PROMIS PF) scores for patients with operatively treated tibial shaft fractures. DESIGN: Retrospective Cohort Study. SETTING: A Level 1 trauma center. PATIENTS: All operatively treated tibial shaft fractures identified by Current Procedural Terminology codes. INTERVENTION: Enrolled patients treated acutely with operative fixation of their tibia. MAIN OUTCOME MEASUREMENTS: MCIDs were calculated by distribution-based and anchor-based methods, calculated from PROMIS PF scores completed at least at two-time points postoperatively. MCIDs were calculated at different time points including overall, 7-12 weeks, 3-6 months, and 6-24 months. MCIDs were calculated for different subgroups including open fractures, closed fractures, any complications, and no complications. RESULTS: MCID for PROMIS PF scores was 5.7 in the distribution-based method and 7.84 (SD 18.65) in the anchor-based method. At 6-24 postoperatively, the months the distribution-based MCID was 5.95 from a postoperative baseline 27.83 (8.74) to 42.85 (9.61), P < 0.001. At 6-24 months, the anchor-based MCID was 10.62 with a score difference between the improvement group of 16.03 (10.73) and the no improvement group of 5.41 (15.75), P < 0.001. Patients with open fractures (distribution-based 6.22 and anchor-based 8.05) and any complications (distribution-based 5.71 and anchor-based 9.29) had similar or higher MCIDs depending on the methodology used than the overall cohort MCIDs. CONCLUSION: This study identified distribution-based MCID of 5.7 and anchor-based MCID of 7.84 calculated from PROMIS PF scores in operative tibial shaft fractures. Distribution-based methods yielded smaller MCIDs than anchor-based methods. These MCID scores provide a standard to compare clinical and investigational outcomes.

BACKGROUND: The diagnosis of a fragility fracture represents an important intervention event for the initiation of medical osteoporosis treatments. However, it is unclear if osteoporosis medications increase the risk of nonunion if administered in the setting of acute fracture. The purpose of the present study was to investigate whether bisphosphonates or selective estrogen receptor modulators/hormone replacement therapy (SERM/HRT) are associated with nonunion following fracture in a Medicare population. METHODS: A retrospective analysis of Medicare claims from 2016 to 2019 was performed to identify patients ≥65 years of age who had a surgically treated long-bone fracture as identified with Current Procedural Terminology (CPT) codes and International Classification of Diseases, 10th Revision (ICD-10) codes. Successive claims were linked for each beneficiary through 1 year following the fracture to determine fracture union status. Multivariable logistic regression models were specified to identify the association between medications and fracture union status while controlling for age, sex, race, Charlson Comorbidity Index (CCI), and fracture type. RESULTS: Of the 111,343 included fractures, 10,452 (9.4%) were associated with a diagnosis of nonunion within 1 year. The nonunion group was younger (79.8 ± 8.3 versus 80.6 ± 8.4 years; p < 0.001), more likely to be White (92.4% versus 90.9%; p < 0.001), and more likely to have a CCI of ≥2 (50.9% versus 49.4%; p < 0.001). Bisphosphonate use was more common in the nonunion group (12.2% versus 11.4%; p = 0.017). When controlling for race, age, sex, and CCI, neither bisphosphonates (OR, 1.06 [95% CI, 0.99 to 1.12]; p = 0.101) nor SERM/HRT (OR, 1.13 [0.93 to 1.36]; p = 0.218) were associated with nonunion. Bisphosphonate use within 90 days post-fracture was not significantly associated with nonunion (OR, 0.94 [95% CI, 0.86 to 1.03]; p = 0.175), and the timing of medication administration did not influence fracture union status. CONCLUSIONS: The rate of nonunion after operatively treated long-bone fractures was 9.4%. In this cohort, use of a bisphosphonate or SERM/HRT was not associated with fracture union status at 1 year. Orthopaedic surgeons should not withhold or delay initiating medical therapies for osteoporosis in the setting of acute fracture out of concern for nonunion. LEVEL OF EVIDENCE: Prognostic Level III .

BACKGROUND: Restoration of a neutral mechanical axis (MA) is important to the success of total knee arthroplasty (TKA). While known differences are present between Asians and Caucasians regarding native knee alignment, it is unknown whether such differences exist amongst Native Hawaiian/Other Pacific Islanders (NHPI) or if utilizing a fixed distal femoral cut of 6° can consistently achieve a neutral MA in these minority racial groups. This study examines the preoperative deformities presented by Asians, Caucasians, and NHPI, and the resulting knee alignment achieved following TKA when a fixed 6° distal femoral cut is targeted for all patients. METHODS: Preoperative and postoperative MA was measured from 835 Asian, 447 Caucasian, and 163 NHPI hip-to-ankle radiographs. All patients underwent TKA in which a standard distal femoral cut of 6° valgus was targeted for all patients. Data were evaluated as continuous variables and by groupings of varus (MA < - 3°), valgus (MA > 3°), and neutral (- 3° ≤ MA ≤ 3°) alignment. RESULTS: Preoperative deformity ranged from 38° varus to 29° valgus. The proportion of Asian and NHPI presenting with varus alignment prior to surgery was significantly greater than Caucasian patients in both males (Asians: 80.6%; Caucasians: 67.0%; NHPI: 79.0%, p = 0.001) and females (Asians: 66.1%; Caucasians: 45.7%; NHPI: 63.2%, p < 0.001). There was no difference in the proportion of patients (72-79%) achieving a neutral MA amongst all three racial groups. CONCLUSION: NHPI appear to have similar preoperative deformities to Asians with both groups having significantly more varus alignment than Caucasians. Despite a wide range of preoperative deformity, application of a fixed distal femoral cut of 6° valgus successfully established a neutral MA equally in the majority of patients across all three racial groups.

BACKGROUND: Large animal fracture models that allow for anatomic fracture fixation are currently lacking. It was hypothesized that a compressed air impaction system can generate a reproducible tibial plafond fracture and be adjustable to create fractures consistent with high and low energy fractures seen in humans. METHODS: Pilot testing of the impaction system was done by impacting polyurethane foam blocks at varying compressed air pressures. A guillotine impaction test was performed on the same foam blocks to create an energy conversion. A total of 12 porcine hindlimb hindlimbs were subjected to low-energy (42.2 J) and high-energy (73.9 J) impact to create tibial plafond fractures. FINDINGS: Guillotine impaction test demonstrated strong correlations between potential energy and foam block impaction depth (R2 = 0.99). Compressed air impaction system test strongly correlated with foam block impaction depth (R2 = 0.99). All six porcine hindlimbs in the low-energy group developed simple coronal split tibial plafond fractures. All six porcine hindlimbs in the high-energy group developed complex, multi-fragmentary tibial plafond fractures. INTERPRETATION: This porcine fracture model created tibial plafond fracture patterns with similar fracture morphology as human patients without violation of the soft tissue structures or adjacent joints. This model would allow for anatomic fixation, the study of post-traumatic osteoarthritis, or the delivery of locally targeted therapeutics to the ankle joint.

Background: Parallax is poorly understood and can mislead surgeons using intraoperative fluoroscopy (IF) to guide cup placement during anterior approach (AA) total hip arthroplasty. The purpose of this study was to examine how changes in fluoroscopic beam positioning in relation to the hip and pelvis affects the projected acetabular image. Methods: An acetabular component was positioned in an anatomic pelvis model in 45° and 20° of abduction and anteversion, respectively using a computer assisted cup targeting system. Fluoroscopic images were taken at various caudal and cranially directed angles with the fluoroscopic beam centered over the hip then pelvis. In each position, four independent observers measured the abduction and anteversion angles of the projected cup image using the same computer targeting system. Results: Cup abduction and anteversion measured 43.5° and 19.5° when IF was centered over the hip and 40.5 and 27.5° when centered over the pelvis in the neutral position. Increasing the caudal direction of the beam 20° increased the projected abduction/anteversion angles by approximately 7°/12° and 9°/16° when centered over the hip and pelvis respectively. Increasing the cranial direction of the beam 20° decreased the measured abduction/anteversion angles by roughly 4°/20° and 4°/24° when centered over the hip and pelvis, respectively. Conclusion: The projected image of the acetabular component can change dramatically depending on fluoroscopic beam position relative to the hip and pelvis. Recognizing the approximate direction and magnitude of change with differing fluoroscopy positions may help surgeons avoid cup malpositioning.

Background: This technique utilizes a full-thickness flap to provide a posterior approach to the scapula for open reduction and internal fracture fixation. The present video article outlines the Judet approach along with an incision modification tip for the surgeon's consideration. Description: Prior to making the incision, perform preoperative planning, patient and C-arm positioning, and identification of the primary fragments of the fracture that necessitate fixation on imaging. The Judet incision is made, and the full-thickness flap is retracted laterally (also described as a "boomerang-shaped" incision, allowing for the flap to be reflected medially). Next, detach and reflect the deltoid off the scapular spine superolaterally to reveal the internervous plane between the infraspinatus and teres minor. Utilize this interval to access the fracture sites while making sure to reflect the infraspinatus cranially, carefully minding the suprascapular neurovascular bundle, and the teres minor inferiorly, protecting the axillary nerve. A longitudinal arthrotomy may then be created parallel to the posterior border of the glenoid, with careful attention paid toward protecting the labrum from iatrogenic injury. The arthrotomy will allow for intra-articular evaluation of the reduction if needed. Primary fractures are then reduced. Reduction is confirmed with use of fluoroscopy, and fixation is applied to maintain the reduction. Alternatives: Most scapular fractures do well with nonoperative treatment, and this has been well documented in the literature. Open reduction and internal fixation has been shown to offer good-to-excellent clinical outcomes with minimal risk of complications in patients with traumatic scapular fractures that necessitate operative treatment1.â¯In certain fractures of the glenoid fossa,â¯operative treatment is necessary to restore normal anatomy, provide stability to the glenohumeral joint, and facilitate functional rehabilitation. Operative treatment is typically reserved for injuries with intra-articular involvement that results in joint incongruity or joint instability2,3. When operative treatment is indicated, an open posterior approach is utilized for some fractures. The posterior Judet approach is the best-known operative technique for such fractures, while other modifications of the Judet technique have also been described in the literature3-5. Rationale: Reports state that scapular body or neck and glenoid fossa fractures account for up to 80% of scapular fractures6.â¯Open reduction and internal fixation of the scapula is an invasive procedure, requiring large incisions and manipulation of soft tissues to expose the various possible fracture sites on the scapula. Thus, numerus surgical techniques have been described that allow surgeons to best tailor treatment to their patients on a case-by-case basis. However, the Judet approach is the workhorse approach for the operative treatment of scapular fractures and is a technique that should be mastered7. The Judet approach allows access to the posterior scapula and provides excellent exposure for fractures that require posterior fixation. The alternative boomerang-shaped incision represents a mirrored version of the Judet incision, with the skin flap reflected medially. The benefit of this modified approach is that it increases the degree of lateral surgical exposure of the scapula and provides easier access to the glenohumeral joint. Expected Outcomes: With this technique for open reduction and internal fixation of scapular fractures, patients can expect comparable outcomes to those described in the literature for the standard Judet technique. These outcomes have been reported as clinical scores and defined as good-to-excellent in a few retrospective case series1,2. Given the variability in scapular fracture morphology, a trauma surgeon should have a strong repertoire of approaches to address these fractures on a case-by-case basis. The Judet approach is one of these necessary approaches and has been shown in the literature to have acceptable outcomes1-3,7. Important Tips: Placing the vertical limb of the boomerang incision too medial can limit lateral exposure of the scapula and make glenohumeral joint access difficult. To avoid this, be sure that the vertical limb of the incision remains in line with the posterior axillary fold.Wound-healing complications can occur following such an extensive surgical approach. A thorough and secure wound closure with repair of the deltoid back to the scapular spine may avoid these problems.Difficulty with intra-articular visualization may occur. Placing a threaded pin into the humeral head or a small distractor across the glenohumeral joint (with a pin in the extra-articular proximal humerus) may improve visualization. Manipulation of the arm can also be beneficial in this regard.Lateral positioning offers easier imaging and allows for exposure to the coracoid or clavicle if these structures are also injured and require operative fixation.Drawing a boomerang-shaped incision with the horizontal limb paralleling the scapular spine and vertical limb along the posterior axillary fold of the arm allows the skin flap to be reflected medially, increasing the degree of lateral surgical exposure of the scapula.After identifying the internervous plane between the infraspinatus and teres minor, take care to reflect the infraspinatus cranially, protecting the suprascapular neurovascular bundle, and the teres minor inferiorly, protecting the axillary nerve.
