RESUMO

PURPOSE: Surgical intervention for lateral compression (LC) 1 and 2 pelvic ring fractures is controversial. Posterior ring stabilization remains the most common mode of initial fixation. However, greater mechanical instability is observed in the anterior component of LC pelvic fractures. This study tested whether reduction and percutaneous superior ramus fixation will decrease the instability of LC pelvic fractures on intraoperative fluoroscopic imaging. METHODS: All adult patients (≥ 18 years) presenting with either a Young-Burgess LC1 or LC2 pelvic ring disruption treated operatively with percutaneous anterior followed by posterior fixation by a single surgeon from July 2021 to June 2023 were retrospectively reviewed. Displacement of the anterior ring to intraoperative manual internal rotation stress examination under fluoroscopy was compared before and after anterior pelvic ring reduction and fixation and prior to posterior pelvic ring fixation. Pre- and post-operative visual analog scores (VAS) for pain were also compared. RESULTS: Twenty-one patients with a mean age of 48.7 years were included. Fifteen patients (71.4%) presented with an LC1, and six (28.6%) with an LC2 injury patterns. Anterior pelvic fixation alone provided 7.5mm reduction in mean displacement of the anterior pelvic ring (pre-operative = 9.2 mm vs. post-operative = 1.6 mm, p < 0.001). VAS significantly decreased from 7.2 one-day pre-operatively to 2.2 twenty-four h post-operatively (p < 0.001). CONCLUSIONS: Reduction and fixation of the anterior pelvic ring prior to posterior fixation for LC1 and LC2 pelvic ring disruptions substantially improves mechanical stability on intraoperative stress examination. Combination of percutaneous anterior and posterior fixation significantly decreased VAS above the MCID 24 h after stabilization.

RESUMO

INTRODUCTION: Patient-centered treatment and research should focus on the outcomes that matter to patients. The primary aim of this study was to determine the outcome preferences of patients after musculoskeletal trauma. The secondary aim was to identify discrepancies between outcome preferences of surgeons and patients. METHODS: A Best-worst scaling choice experiment survey was administered to patients with operative lower extremity injuries and orthopaedic surgeons who take trauma call. Participants completed 13 choice sets of 3 randomly-ordered outcomes, including: a full recovery (back to normal) without any problems; a problem that requires additional surgery or hospital stay versus medication or treatment in clinic/emergency department; minimal to moderate versus severe pain for 6 weeks; need for crutches/walker versus wheelchair for 6-12 weeks; being unable to work for 6-12 weeks; requiring 2-4 weeks in a facility; a perfect versus poor or worst-possible EuroQol 5 Dimension (EQ-5D) score at 1 year; and death. Within each set, participants ranked their "most-preferred" to "least-preferred" outcomes. Responses were aggregated to calculate the relative importance, or marginal utility, of each outcome stratified by respondent type. RESULTS: Fifty-five patients and 65 surgeons participated. The most preferred outcome for patients and surgeons was a full recovery (back to normal) without any problems, followed by minimal to moderate pain for 6 weeks and a perfect EQ-5D score. The least preferred outcomes were death and the worst EQ-5D score, which had similar marginal utility, followed by a poor EQ-5D score and a problem that needs another surgery or stay at a hospital, which also had similar marginal utility. Surgeons, in comparison to patients, assigned a higher marginal utility to perfect EQ-5D scores at one year (3.55 vs. 2.03; p < 0.0001) and a 2-4 week stay in a facility (0.52 vs. -0.21; p = 0.001), and a lower marginal utility to severe pain for 6 weeks (-0.58 vs. -0.08; p = 0.04) and a poor EQ-5D score (-1.88 vs. -1.03; p = 0.02). CONCLUSIONS: A full recovery (back to normal) without any problems was the most-preferred outcome for both patients and surgeons. Patient-centered care and research should focus on both patients' return to baseline and the avoidance of complications. LEVEL OF EVIDENCE: N/A.

RESUMO

PURPOSE: To identify a cohort of isolated medial tibial plateau fractures treated with surgical fixation and to categorize them by Moore and Wahlquist classifications in order to determine the rate of complications with each fracture morphology and the predictive value of each classification system. We hypothesized there would be high rates of neurovascular injury, compartment syndrome, and complications overall with a higher incidence of neurovascular injury in Moore type III rim avulsion fractures and Wahlquist type C fractures that enter the plateau lateral to the tibial spines. METHODS: Patients who presented to six Level I trauma centers between 2010 and 2021 who underwent surgical fixation for isolated medial tibial plateau fractures were retrospectively reviewed. Data including demographics, radiographs, complications, and functional outcomes were collected. RESULTS: One hundred and fifty isolated medial tibial plateau fractures were included. All patients were classified by the Wahlquist classification of medial tibial plateau fractures, and 139 patients were classifiable by the Moore classification of tibial plateau fracture-dislocations. Nine percent of fractures presented with neurovascular injury: 5 % with isolated vascular injury and 6 % with isolated nerve injury. There were no significant differences in neurovascular injury by fracture type (Wahlquist p = 0.16, Moore p = 0.33). Compartment syndrome developed in two patients (1.3 %). The average final range of motion was 0.8-122° with no difference by Wahlquist or Moore classifications (p = 0.11, p = 0.52). The overall complication rate was 32 % without differences by fracture morphology. The overall rate of return to the operating room (OR) was 25 %. CONCLUSIONS: Isolated medial tibial plateau fractures often represent fracture-dislocations of the knee and should receive a meticulous neurovascular exam on presentation with a high suspicion for neurovascular injury. No specific fracture pattern was found to be predictive of neurovascular injuries, complications, or final knee range of motion. Patients should be counseled pre-operatively regarding high rates of return to the OR after the index surgery.

RESUMO

PURPOSE: Determine if anterior internal versus supra-acetabular external fixation of unstable pelvic fractures is associated with care needs or discharge. METHODS: A retrospective cohort study was performed at two tertiary trauma referral centers. Adults with unstable pelvis fractures (AO/OTA 61B/61C) who received operative fixation of the anterior and posterior pelvic ring by two orthopedic trauma surgeons from October 2020 to November 2022 were included. The primary outcome was discharge destination. Secondary outcomes included intensive care unit (ICU) or ventilator days, length of stay, and hospital charges. RESULTS: Eighty-three eligible patients were 38.6% female, with a mean age of 47.2 ± 20.3 years and BMI 28.1 ± 6.4 kg/m2. Fifty-nine patients (71.1%) received anterior pelvis internal fixation and 24 (28.9%) received external fixation. External fixation was associated with weight-bearing restrictions (91.7% versus 49.2%, p = 0.01). No differences in demographic, functional status, insurance type, fracture classification, or injury severity measures were observed by treatment. Internal versus external anterior pelvic fixation was not associated with discharge to home (49.2% versus 29.2%, p = 0.10), median ICU days (3.0 [interquartile range (IQR) 7.8 versus 5.5 [IQR 4.3], p = 0.14, ventilator days (0 [IQR 6.0] versus 0 [IQR 2.8], p = 0.51), length of stay (13.0 [IQR 13.0] versus 17.5 (IQR 20.5), p = 0.38), or total hospital charges (US dollars 180,311 [IQR 219,061.75] versus 243,622 [IQR 187,111], p = 0.14). CONCLUSIONS: Anterior internal versus supra-acetabular external fixation of unstable pelvis fractures was not significantly associated with discharge destination, critical care, hospital length of stay, or hospital charges. This sample may be underpowered to detect differences between groups. LEVEL OF EVIDENCE: Therapeutic Level IV.

RESUMO

PURPOSE: To determine if subchondral rafting wires retained as adjunctive tibial plateau fracture fixation affect postoperative articular subsidence. METHODS: A retrospective cohort study was conducted at one Level 1 trauma center and one academic university hospital. Consecutive adults with closed, displaced OTA/AO 41B/C tibial plateau fractures treated between 2018 and 2023 with open reduction internal fixation were included. Patients who were not ambulatory, with contralateral injuries limiting weight bearing, and without follow-up radiographs of the injured extremity were excluded. The intervention was retention of subchondral rafting wires as definitive fixation. The primary outcome was linear articular surface subsidence between postoperative and follow-up AP knee radiographs. Linear subsidence was compared between groups using Welch's two sample t test. Associations of linear subsidence with patient, injury, and treatment characteristics were assessed by multivariable linear regression. RESULTS: We identified 179 patients of a mean age of 44 ± 14 years, of whom 15 (8.4%) received subchondral rafting wires. Median follow-up was 121 days. No patients who received rafting wires as definitive implants experienced linear subsidence ≥ 2 mm, while 22 patients (13.4%) who did not receive rafting wires experienced linear subsidence ≥ 2 mm (p = 0.130). Subchondral rafting wires were associated with less linear subsidence (0.3 mm [95% confidence interval - 0.3-0.9 mm] vsersus 1.0 mm [- 0.9-2.9 mm], p < 0.001). The depth of linear subsidence was significantly associated on multivariable regression with male sex, depressed plateau area, active smoking, and retained rafting wires. CONCLUSION: Subchondral rafting wires were associated with a small reduction in articular subsidence after internal fixation of tibial plateau fractures. Routine rafting wires may be useful for patients and fractures at high risk of articular subsidence.

RESUMO

INTRODUCTION: Distal femur fractures account for 3-6% of all femur fractures. Internal fixation of most distal femur fractures with an anatomic lateral locking plate should permit some motion at the metaphyseal portion of the fracture when secondary bone healing is planned by the operating surgeon. While several studies have been performed evaluating union rates for distal femur fractures with stainless steel and titanium plates, the timing of callus formation between stainless steel and titanium implants used as bridge plates for distal femur fractures (AO/OTA 33-A and -C) has been investigated to a lesser extent. We hypothesize that callus will be visualized earlier with post-operative radiographs with titanium versus stainless steel bridge plates. METHODS: We retrospectively reviewed a consecutive cohort of patients over 18 years of age with acute AO/OTA 33-A and 33-C fracture patterns treated with an isolated stainless steel or titanium lateral bridge plate within 4 weeks of injury by a single fellowship-trained orthopedic trauma surgeon from 2011 to 2020 at one academic Level 1 trauma center. An independent, fellowship-trained orthopedic trauma attending surgeon reviewed anterior-posterior (AP) and lateral radiographs from every available post-operative clinic visit and graded them using the Modified Radiographic Score for Tibia (mRUST). RESULTS: Twenty-five subjects were included in the study with 10 with stainless steel and 15 with titanium plates. There were no significant differences in demographics between both groups, including age, sex, BMI, injury classification, open versus closed, mechanism, and laterality. Statistically significant increased mRUST scores, indicating increased callus formation, were seen on 12-week radiographs (8.4 vs. 11.9, p = 0.02) when titanium bridge plates were used. There were no statistically significant differences in mRUST scores at 6 or 24-weeks, but scores in the titanium group were higher in at every timepoint. DISCUSSION: In conclusion, we observed greater callus formation at 12 weeks after internal fixation of 33-A and 33-C distal femur fractures treated with titanium locked lateral distal femoral bridge plates compared to stainless steel plates. Our data suggest that titanium metallurgy may have quicker callus formation compared to stainless steel if an isolated, lateral locked bridge plate is chosen for distal femur fracture fixation.

RESUMO

OBJECTIVES: To quantify how patients with lateral compression type 1 (LC1) pelvis fracture value attributes of operative versus nonoperative treatment. DESIGN: Discrete choice experiment. SETTING: Three US Level 1 trauma centers. PATIENT SELECTION CRITERIA: Adult survivors of an LC1 pelvis treated between June 2016 and March 2023 were identified from institutional registries. The choice experiment was administered as a survey from March through August 2023. OUTCOME MEASURES AND COMPARISONS: Participants chose between 12 hypothetical comparisons of treatment attributes including operative or nonoperative care, risk of death, severity of pain, risk of secondary surgery, shorter hospital stay, discharge destination, and independence in ambulation within 1 month of injury. The marginal utility of each treatment attribute, for example, the strength of participants' aggregate preference for an attribute as indicated by their survey choices, was estimated by multinomial logit modeling with and without stratification by treatment received. RESULTS: Four hundred forty-nine eligible patients were identified. The survey was distributed to 182 patients and collected from 72 patients (39%) at a median 2.3 years after injury. Respondents were 66% female with a median age of 59 years (IQR, 34-69 years). Before injury, 94% ambulated independently and 75% were working; 41% received operative treatment. Independence with ambulation provided the highest relative marginal utility (21%, P < 0.001), followed by discharge to home versus skilled nursing (20%, P < 0.001), moderate versus severe postdischarge pain (17%, P < 0.001), shorter hospital stay (16%, P < 0.001), secondary surgery (15%, P < 0.001), and mortality (10%, P = 0.02). Overall, no relative utility for operative versus nonoperative treatment was observed (2%, P = 0.54). However, respondents strongly preferred the treatment they received: operative patients valued operative treatment (utility, 0.37 vs. -0.37, P < 0.001); nonoperative patients valued nonoperative treatment (utility, 0.19 vs. -0.19, P < 0.001). CONCLUSIONS: LC1 pelvis fracture patients valued independence with ambulation, shorter hospital stay, and avoiding secondary surgery and mortality in the month after their injury. Patients preferred the treatment they received rather than operative versus nonoperative care.

RESUMO

OBJECTIVE: To determine whether intrawound vancomycin changes the bacteriology of surgical site infection pathogens and investigate the emergence of antibiotic-resistant pathogens. DESIGN: Secondary analysis of phase III, prospective, randomized clinical trial. SETTING: Thirty-six US trauma centers. PATIENT SELECTION CRITERIA: Patients who became infected after fixation of tibial plateau or pilon fracture. OUTCOME MEASURES AND COMPARISONS: Pathogen types and bacterial susceptibilities as determined from routine clinical culture in the operating room. RESULTS: Seventy-four patients were studied who were 67.5% male with a mean age of 48.6 years. A lower proportion of gram-positive cocci was observed in the vancomycin powder compared with the standard-of-care group (3.7% vs. 8.0%, P = 0.01). Methicillin-resistant Staphylococcus aureus infection incidence was comparable in both the vancomycin powder and the standard-of-care groups, but rates of methicillin-susceptible S. aureus infections were lower in the treatment group (1.4% vs. 4.8%, P = 0.01). The incidence of coagulase-negative Staphylococci and gram-negative rod infections were similar in both groups. There was no significant difference in susceptibilities between groups in rates of vancomycin-resistant enterococcus. CONCLUSIONS: Topical vancomycin powder decreases the likelihood of gram-positive infections consistent with the biologic activity of vancomycin. Fewer methicillin-susceptible S. aureus and coagulase-negative Staphylococci infections were observed in the group treated with vancomycin powder. An effect of vancomycin powder on methicillin-resistant S. aureus infection risk was not detected given the low incidence in both the intrawound vancomycin and the standard-of-care groups. There was no emergence of gram-negative rod infections or increased resistance patterns observed. Use of topical vancomycin powder does not seem to produce infections in these patients with greater antibiotic resistance than would have occurred without its use. LEVEL OF EVIDENCE: Therapeutic Level II. See Instructions for Authors for a complete description of levels of evidence.

RESUMO

OBJECTIVE: Assess associations between fellowship training, procedure, and performance in femoral neck fracture (FNF) surgery on adults by American Board of Orthopaedic Surgery (ABOS) Part II Examination candidates. SETTING: ABOS SCRIBE database exam years 2007-2020. PARTICIPANTS: 6,777 candidates performing 39,283 FNF surgeries on adults age ≥ 50 years. INTERVENTION: Fellowship training. MAIN OUTCOME MEASUREMENTS: Case volume; procedure performed: internal fixation (IF), hemiarthroplasty (HA), or total hip arthroplasty (THA); complications; readmission; reoperation. RESULTS: Over the observation period, fewer candidates reported FNF surgery (68% overall, -0.6%/year, R2=0.80) while more candidates reported fellowship training (87% overall, +1.4%/year, R2=0.81). The rate of any complication was significantly associated with fellowship training (32% overall, p<0.001). Readmission (12%, p=0.080) and reoperation (5%, p=0.531) were not significantly associated with fellowship training. The odds of any complication (odds ratio [OR]=-0.03 [95% CI -0.07 to -0.001] per 10 cases) and surgical complication (OR=-0.12 [95% CI -0.17 to -0.07] per 10 cases) were negatively associated with candidate FNF case volume. 3,396 THA for FNF were performed (8% of cases). THA use increased 25 cases/year (R2=0.83) and was associated with adult reconstruction (p<0.001) and oncology (p<0.001) fellowship training. Any complication of THA for FNF (32%, p=0.261), readmission (9% overall, p=0.321), and reoperation (5%, p=0.200) were not significantly associated with fellowship training. CONCLUSIONS: Between 2007-2020, femoral neck fracture surgery was performed by fewer ABOS Part II Examination candidates and there was greater use of THA. Over this time period there was a greater prevalence of fellowship training but complications were not associated with fellowship training. Complications were associated with FNF case volume. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

RESUMO

OBJECTIVES: Occult instability in minimally displaced lateral compression (LC) pelvic ring injuries may have clinical relevance for treatment. We describe two novel LC pelvis fracture stress examinations - pelvic binder stress radiography (PBR) and pelvic binder stress bladder manometry (PBM) - which do not require sedation, anesthesia, patient transport, or radiation of personnel. METHODS: A biomechanical study was performed with five fresh elderly cadavers. Sequential osteotomies of the pelvis simulated increasingly unstable LC pelvis fracture patterns (OTA/AO 61A2.2, 61B1.1a, 61B1.1b, 61B2.1). Compressive force was quantitatively applied using a pelvic binder and scale. Pelvis fracture displacement was measured on AP and inlet fluoroscopic views. Pelvic bladder pressure (PBM) was measured using a Foley catheter as a water column. RESULTS: Fracture displacement strongly correlated with force applied (R2=0.600-0.963). PBR discriminated between simulated LC injuries. Mean displacement of 61B1.1b injuries >1cm was observed at 3.8kg on AP view and 5kg on inlet view. Mean displacement of 61B1.1a injuries >1cm was observed at 8.2kg on AP view and 9.3kg on inlet view. 61A2.2 injuries did not displace >1cm at forces up to 10kg. >95% of 61B1.1a and 61B1.1b injuries displaced >1cm at 10kg. PBM moderately correlated with force applied (R2=0.517-0.842) but did not discriminate between LC injuries. CONCLUSIONS: PBR is feasible, precisely quantified occult mechanical instability in simulated LC pelvis fractures in response to reproducible applied force, and discriminated between simulated LC pelvis fractures. PBM did not discriminate between simulated LC fractures. A clinical trial to validate the safety and efficacy of PBR for assessing occult instability in LC pelvis fracture is warranted.

RESUMO

PURPOSE: Underweight patients experience poor outcomes after elective orthopaedic procedures. The effect of underweight body mass index (BMI) on complications after acetabular fracture is not well-described. We evaluate if underweight status is associated with inpatient complications after acetabular fractures. METHODS: Adult patients (≥ 18 years) presenting with acetabular fracture between 2015 and 2019 were identified from Trauma Quality Program data. Adjusted odds (aOR) of any inpatient complication or mortality were compared between patients with underweight BMI (< 18.5 kg/m2) and normal BMI (18.5-25 kg/m2) using multivariable logistic regression and stratifying by age ≥ 65 years. RESULTS: The 1299 underweight patients aged ≥ 65 years compared to 11,629 normal weight patients experienced a 1.2-times and 2.7-times greater aOR of any complication (38.6% vs. 36.6%, p = 0.010) and inpatient mortality (7.9% vs. 4.2%, p < 0.001), respectively. The 1688 underweight patients aged 18-64 years compared to 24,762 normal weight patients experienced a 1.2-times and 1.5-times greater aOR of any inpatient complication (38.9% vs. 34.8%, aOR p = 0.006) and inpatient mortality (4.1% vs. 2.5%, p < 0.001), respectively. CONCLUSION: Underweight adult patients with acetabular fracture are at increased risk for inpatient complications and mortality, particularly those ≥ 65 years old. LEVEL OF EVIDENCE: Prognostic Level III.

RESUMO

BACKGROUND: Acute total hip arthroplasty (THA) may be an alternative or an adjuvant to internal fixation for surgical treatment of acetabular fractures. We investigate recent trends in the operative management of acetabular fractures. We hypothesize that the incidence of acute THA for acetabular fractures has increased over time. METHODS: 4569 middle-aged (45-64 years) and older adults (≥ 65 years) who received acute operative management of an acetabular fracture within 3 weeks of admission between 2010 and 2020 were identified from the United States Nationwide Inpatient Sample database. Treatment was classified as open reduction internal fixation (ORIF), THA, or combined ORIF and THA (ORIF + THA). Patients were stratified by age ≥ 65 years old. Associations between demographic factors and the incidence of each procedure over the study period were modeled using linear regression. RESULTS: The relative incidence of treatments was 80.9% ORIF, 12.1% THA, and 7.0% ORIF + THA. Among patients aged 45-64 years old, THA increased 4.8% [R2 = 0.62; ß1 = 0.6% (95% Confidence Interval (CI) 0.2-0.9%)] and ORIF + THA increased 2.6% [R2 = 0.73; ß1 = 0.3% (95% CI 0.2-0.4%)], while the use of ORIF decreased 7.4% [R2 = 0.75; ß1 = -0.9% (95% CI -1.2 to -0.5%)]. Among patients ≥ 65 years old, THA increased 16.5% [R2 = 0.87; ß1 = 1.7% (95% CI 1.2-2.2%)] and ORIF + THA increased 5.0% [R2 = 0.38, ß1 = 0.6% (95% CI 0.0-1.3%)], while ORIF decreased 21.5% [R2 = 0.75; ß1 = -2.4% (95% CI -3.45 to -1.3%)]. CONCLUSION: The treatment of acetabular fractures with acute THA has increased in the last decade, particularly among older adults.

RESUMO

INTRODUCTION: Obesity remains a global epidemic. The effect of obesity on the risk of complications after acetabular fracture is unknown. Here, we evaluate the effect of BMI on early complications and mortality after acetabular fracture. We hypothesize that the risk of inpatient complications and mortality will be greater in patients with high BMI when compared to those with normal BMI. METHODS: Adult patients with acetabular fracture were identified via the Trauma Quality Improvement Program data from 2015 to 2019. The primary outcome was overall complication rate with reference to normal-weight patients (BMI = 25-30 kg/m2). The secondary outcome was rates of death. The association of obesity class on the primary and secondary outcomes was assessed using Bonferroni-corrected multiple logistic regression models considering patient, injury, and treatment covariates. RESULTS: A total of 99,721 patients with acetabular fracture were identified. Class I obesity (BMI = 30-35 kg/m2) was associated with 1.2 greater adjusted relative risk (aRR; 95% confidence interval (CI) 1.1-1.3) of any adverse event, without significant increases in adjusted risk of death. Class II obesity (BMI = 35-40 kg/m2) was associated with aRR = 1.2 (95% CI 1.1-1.3) of any adverse event and aRR = 1.5 (95% CI 1.2-2.0) of death. Class III obesity (BMI ≥ 40 kg/m2) was associated with aRR = 1.3 (95% CI 1.2-1.4) of any adverse event and aRR = 2.3 (95% CI 1.8-2.9) of death. CONCLUSION: Obesity is associated greater risk of adverse events and death following acetabular fracture. Obesity severity classification scales with these risks.

RESUMO

PURPOSE: Open reduction internal fixation of tibial plateau and pilon fractures may be complicated by deep surgical site infection requiring operative debridement and antibiotic therapy. The management of superficial surgical site infection is controversial. We sought to determine whether superficial infection is associated with an increased risk of deep infection requiring surgical debridement after fixation of tibial plateau and pilon fractures. METHODS: This is a secondary analysis of data from the VANCO trial, which included 980 adult patients with a tibial plateau or pilon fracture at elevated risk of infection who underwent open reduction internal fixation with plates and screws with or without intrawound vancomycin powder. An association of superficial surgical site infection with deep surgical site infection requiring debridement surgery and antibiotics was explored after matching on risk factors for deep surgical site infection. RESULTS: Of the 980 patients, we observed 30 superficial infections (3.1%) and 76 deep infections (7.8%). Among patients who developed a superficial infection, the unadjusted incidence of developing a deep infection within 90 days was 12.8% (95% confidence interval [CI] 1.3-24.2%). However, after a 3:1 match on infection risk factors, the 90-day marginal probability of a deep surgical site infection after sustaining a superficial infection was 6.0% (95% CI - 6.5-18.5%, p = 0.35). CONCLUSION: Deep infection after superficial infection is uncommon following operative fixation of tibial plateau and pilon fractures. Increased risk of subsequent deep infection attributable to superficial infection was inconclusive in these data. LEVEL OF EVIDENCE: Prognostic Level II.

RESUMO

PURPOSE: To estimate survival of acetabular fracture repair by tracking patients across healthcare encounters. We hypothesized that hip survival estimated this way would be lower than reported by single-surgeon or single-center series not capturing censored reoperations. METHODS: Retrospective health insurance administrative database cohort study. All claimed healthcare encounters for employer-sponsored health insurance beneficiaries aged 18-65 years without pre-existing hip pathology with a newly diagnosed acetabular fracture were identified between October 1, 2015, through December 31, 2018. The intervention was open reduction internal fixation of acetabular fracture during index admission. The primary outcome was survival of the acetabular fracture repair to subsequent reoperation by arthroscopy, arthrotomy for drainage of infection, implant removal, revision acetabular fixation, hip arthroplasty, hip resection, or arthrodesis. RESULTS: 38 reoperation procedures on the fractured acetabulum in 852 patients occurred within 2 years (incidence 4.5%). Total hip arthroplasty (2.5%) and revision internal fixation (1.5%) accounted for most early reoperations. Multivariable Cox regression identified an association between reoperation and increasing patient age (hazard ratio = 1.4 per decade, p < 0.01). The prevalence of any mental health condition was 29%. CONCLUSIONS: Non-elderly adults with employer-sponsored insurance who sustain acetabular fractures have a greater burden of mental health disease than similarly insured patients without these injuries. Survival of the native acetabulum after fracture fixation exceeded 95% at 2 years and decreased with increasing patient age. LEVEL OF EVIDENCE: Level III, Prognostic Study.

RESUMO

BACKGROUND: Patients with traumatic pelvic ring injury may present with hypotension secondary to hemorrhage. Preperitoneal pelvic packing (PPP) and angioembolization (AE) are alternative interventions for management of hypotension associated with pelvic ring injury refractory to resuscitation and circumferential compression. We hypothesized that PPP may be independently associated with increased risk of venous thromboembolism (VTE) compared with AE in patients with hypotension and pelvic ring injury. METHODS: Adult patients with pelvic ring injury and hypotension managed with PPP or AE were retrospectively identified in the Trauma Quality Improvement Program (TQIP) database from 2015 to 2019. Patients were matched on a propensity score for receiving PPP based on patient, injury, and treatment factors. The primary outcome was the risk of VTE after matching on the propensity score for treatment. The secondary outcomes included inpatient clinically important deep vein thrombosis, pulmonary embolism, respiratory failure, mortality, unplanned reoperation, sepsis, surgical site infection, hospital length of stay, and intensive care unit (ICU) length of stay. RESULTS: In this study, 502 patients treated with PPP and 2,439 patients treated with AE met inclusion criteria. After propensity score matching on age, smoking status, Injury Severity Score, Tile B or C pelvic ring injury, bilateral femoral fracture, serious head injury, units of plasma and platelets given within 4 hours of admission, laparotomy, and level-I trauma center facility designation, 183 patients treated with PPP and 183 patients treated with AE remained. PPP, compared with AE, was associated with a 9.8% greater absolute risk of VTE, 6.5% greater risk of clinically important deep vein thrombosis, and 4.9% greater risk of respiratory failure after propensity score matching. CONCLUSIONS: PPP for the management of hypotension associated with pelvic ring injury is associated with higher rates of inpatient VTE events and sequelae compared with AE. LEVEL OF EVIDENCE: Prognostic Level III . See Instructions for Authors for a complete description of levels of evidence.

RESUMO

Metadiaphyseal proximal radius fractures blur the distinction between the radial neck and radial shaft fractures. Operative management presents unique technical challenges both in terms of surgical approach and fixation method. We discuss relevant anatomy, safe surgical approach, and options and techniques for fracture fixation. We describe 6 patients who achieved satisfactory functional outcomes, even in cases of severe bone loss secondary to ballistic trauma. An extensile dorsal approach with exposure of the posterior interosseous nerve is recommended when normal soft tissue intervals have not already been extensively disrupted. Robust fixation can be achieved by contouring and repurposing a variety of plates such as a variety of mini fragment plates (2.4 mm T or Y-plates), flexible nails, or even distal radius plates.

RESUMO

AIMS: Antibiotic administration, severity of injury, and debridement are associated with surgical site infection (SSI) after internal fixation of open fractures. We sought to validate a time-dependent treatment effect of antibiotic administration. PATIENTS: Consecutive open fracture patients at a level 1 trauma center with minimum 30-day follow-up were identified from an orthopaedic registry from 2013-2017. METHODS: The primary endpoint was SSI within 90 days. A threshold time to antibiotic administration associated with SSI was ascertained by receiver-operator analysis. A Cox proportional hazards model adjusted for age, smoking, and drug use determined the treatment effect of antibiotic administration within the threshold period. RESULTS: Ten percent of 230 patients developed a SSI. There was a trend for patients who did not develop an SSI to receive antibiotics earlier than those who did develop an SSI (61 minutes, IQR 33-107 vs 83 minutes, IQR 40-186), p=0.053). Intravenous antibiotic administration after 120 minutes of presentation of an open fracture to emergency department was significantly associated with a 2.4 increased hazard of surgical site infection (p=0.036) within 90 days. CONCLUSION: Antibiotic administration greater than 120 minutes after ED presentation of an open fracture was associated with an increased risk of SSI.

RESUMO

A prospective observational cohort of 20 primary total hip arthroplasty (n = 12) and total knee arthroplasty (n = 8) patients (mean age: 63 ± 6 years) was passively monitored with a consumer-level wearable activity sensor before and 6 weeks after surgery. Patients were clustered by minimal change or decreased activity using sensor data. Decreased postoperative activity was associated with greater pain reduction (-5.5 vs -2.0, P = .03). All patients surpassed minimal clinical benefit thresholds of total joint arthroplasty (TJA) (Hip Disability and Osteoarthritis Score Junior 30.5 vs 20.8, P = .23; Knee Injury and Osteoarthritis Outcome Score Junior 23.3 vs 18.2, P = .77) within 6 weeks. Patients who objectively "take it easy" after TJA may experience less pain with no difference in early subjective outcome. Remote, passive analysis of outpatient wearable sensor data may permit real-time detection of early problems after TJA.
