ABSTRACT

OBJECTIVES: To explore the association between time to surgery (TTS) and postoperative complications in geriatric patients with acetabular fractures. DESIGN: Retrospective cohort study. SETTING: Level I trauma center. PATIENTS/PARTICIPANTS: 51 consecutive geriatric patients (60 years of age or older) who presented to a Level 1 trauma center for surgical fixation of an acetabular fracture between 2013 and 2020. MAIN OUTCOME MEASUREMENT: The primary and secondary outcomes were 30-day postoperative complications and length of hospital stay (LOS), respectively. TTS was determined by time between arrival to ED and time of surgery, with a threshold of 48 hours (early vs. delayed TTS group). RESULTS: Nineteen patients (37.3%) had ≥1 postoperative complications. Patients in the delayed TTS group had 5× higher odds of developing ≥1 complications (odds ratio: 4.86, confidence interval: 1.48-15.96). There were no 30-day mortalities in either group. Patients in the delayed TTS group had an average LOS of 19 days compared with early TTS patients who had an average LOS of 12 days ( P = 0.040). CONCLUSION: Geriatric patients with acetabular fractures with delayed TTS had increased postoperative complications and LOS. These data suggest that expedited care may have a similar protective effect in geriatric patients with acetabular fractures, as it does in the acute hip fracture population. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

ABSTRACT

BACKGROUND: Frailty is a well-established risk factor in patients undergoing total knee arthroplasty (TKA). How age modifies the impact of frailty on outcomes in these patients, however, remains unknown. In this study, we aimed to describe and evaluate the applicability of a novel risk stratification tool-the age-adjusted modified Frailty Index (aamFI)-in patients undergoing TKA. METHODS: A national database was queried for all patients undergoing primary TKA from 2015 to 2019. There were 271,271 patients who met inclusion criteria for this study. First, outcomes were compared between chronologically young and old frail patients. In accordance with previous studies, the 75th percentile of age of all included patients (73 years) was used as a binary cutoff. Then, frailty was classified using the novel aamFI, which constitutes the 5-item mFI with the addition of 1 point for patients ≥73 years. Multivariable logistic regressions were then used to investigate the relationship between aamFI and postoperative outcomes. RESULTS: Frail patients ≥73 years had a higher incidence of complications compared to frail patients <73 years. There was a strong association between aamFI and complications. An aamFI of ≥3 (reference aamFI of 0) was associated with an increased odds of 30-day mortality (odds ratio [OR] 8.6, 95% CI 5.0-14.8), any complication (OR 3.1, 95% CI 2.9-3.3), deep vein thrombosis (OR 1.5, 95% CI 1.2-1.8), and nonhome discharge (OR 6.1, 95% CI 5.8-6.4; all P < .001). CONCLUSION: Although frailty negatively influences outcomes following TKA in patients of all ages, chronologically old, frail patients are particularly vulnerable. The aamFI accounts for this and represents a simple, but powerful tool for stratifying risk in patients undergoing primary TKA.

ABSTRACT

BACKGROUND: Success rates for surgical management of chronic exertional compartment syndrome (CECS) are historically lower with release of the deep posterior compartment compared with isolated anterolateral releases. At our institution, when a deep posterior compartment release is performed, we routinely examine for a separate posterior tibial muscle osseofascial sheath and release it if present. PURPOSE: Within the context of this surgical approach, the aim of the current study was to compare long-term patient satisfaction and activity levels in patients who underwent 2-compartment fasciotomy versus a modified 4-compartment fasciotomy for CECS. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Patients treated with fasciotomy for lower extremity CECS from 2007 to 2017 were retrospectively identified. In all patients in whom a 4-compartment fasciotomy was indicated, the tibialis posterior muscle was examined for a separate osseofascial sheath, which was released when present. Patients completed a series of validated patient-reported outcome (PRO) surveys, including the Marx activity score, Tegner activity score, 12-Item Short Form Health Survey, and Likert score for patient satisfaction. RESULTS: Of the 48 patients who were included in this study, 34 (71%) patients with a total of 52 operative limbs responded and completed PRO surveys. The mean follow-up for the entire cohort was 5.5 ± 2.6 years. Of the 34 patients, 23 (68%) underwent 2-compartment fasciotomy and 11 (32%) underwent 4-compartment fasciotomy. Among the patients in the 4-compartment fasciotomy group, 7 (64%) were found to have a fifth compartment. No significant difference was found in any of the validated PRO measures between patients who had a 2- versus 4-compartment fasciotomy or those who underwent 4-compartment fasciotomy with or without a present fifth compartment. At a mean 5.5-year follow-up, 74% of patients who underwent a 2-compartment release reported good or excellent outcomes compared with 82% of patients who underwent our modified 4-compartment release. CONCLUSION: The current study, which included the longest follow-up on CECS patients in the literature, demonstrated that the addition of a release of the posterior tibial muscle fascia led to no significant difference in PRO measures between patients who underwent a 2- versus 4-compartment fasciotomy, when historically the 2-compartment fasciotomy group has had higher success rates.

ABSTRACT

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: To compare clinical outcomes and radiographic parameters between patients treated with a posterior spinal fusion that had a lower instrumented vertebra at T11, T12, and L1. BACKGROUND: Posterior instrumented fusions are well established for treating patients with adolescent idiopathic scoliosis (AIS). Fusions limited to the thoracic spine can adequately correct a spinal deformity while preserving lumbar segmental mobility. However, fusions that end at the thoracolumbar junction have been proposed to cause adjacent segment complications. Studies comparing outcomes between patients who were treated with fusions that end at the thoracolumbar junction with varying LIVs are limited. METHODS: A multicenter database was queried for patients with AIS that had Lenke Type 1 and 2 curves treated with a fusion that had an LIV at T11, T12, or L1. Coronal curve magnitude, degree of junctional kyphosis, C7-central sacral line, thoracic apical translation, and sagittal stable vertebrae were measured. Clinical and functional outcomes were assessed using the Scoliosis Research Society-22 (SRS-22) questionnaire and lumbar flexibility testing. RESULTS: The lower instrumented level was below the sagittal stable vertebrae in 22.7%, 40%, and 66.2% of patients in the LIV-T11, T12, and L1 groups, respectively (p < 0.001). The 5-year postoperative lumbar curve magnitudes were 20.3°, 16.3°, and 14.0° for T11, T12, and L1-LIV, respectively (p < 0.001). No patients in the T11 group (0%), two patients in the T12 group (2.5%), and one patient in the L1 (0.8%) group developed distal junctional kyphosis (p = 0.5). The 5-year postoperative total SRS-22 scores were 4.21, 4.50, and 4.38 (p = 0.029). Lumbar flexion decreased by 0.78 cm in the T11-LIV group, increased by 0.01 cm in the T12-LIV group, and decreased by 0.15 cm in the L1-LIV group (p = 0.434). CONCLUSION: There was no significant difference in SRS-22 scores, development of distal junctional kyphosis or loss of lumbar mobility between patients treated with a spinal fusion that had an LIV at T11, T12, or L1. LEVEL OF EVIDENCE: Level III.

ABSTRACT

OBJECTIVES: To explore the association between increased time in traction and in-hospital pulmonary complications in patients with acetabular fractures. DESIGN: Retrospective. SETTING: Level I trauma center. PATIENTS/PARTICIPANTS: One hundred ninety consecutive patients. INTERVENTION: Application of skeletal traction before fixation of acetabular fracture. MAIN OUTCOME MEASUREMENTS: The primary outcome measure was pulmonary complication as defined by pulmonary embolism, pneumonia, and acute respiratory distress syndrome. Secondary outcome measures included length of intensive care unit stay (in days), total length of hospital stay (in days), deep hardware-associated infection, subsequent conversion to total hip arthroplasty, urinary tract infection, and lower-extremity deep venous thrombosis. RESULTS: The mean time in traction for patients who developed a pulmonary complication was 210 hours compared with 62 hours for those who did not (P < 0.001). After controlling for Injury Severity Score, chest injury, and concomitant long bone injury requiring intramedullary nailing, the odds of developing a pulmonary complication for patients who spent longer than 120 hours in traction were over 40 times higher than those treated within 5 days (P < 0.001). The mean intensive care unit stay for patients who spent at least 120 hours in traction was 17 days compared with 5 days for those treated in less than 120 hours (P < 0.001). CONCLUSION: Early definitive fixation and decreased time in skeletal traction is associated with a lower rate of complications in patients with acetabular fractures. Our results would suggest that fixation of acetabular fractures before 120 hours (5 days) confers a significant risk-reduction benefit. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

ABSTRACT

INTRODUCTION: The purpose of the present study was to evaluate the prevalence of closed suction drainage after a Kocher-Langenbeck (K-L) approach for surgical fixation of acetabular fractures and to determine the impact of closed suction drainage on patient outcomes. METHODS: This retrospective study reports on 171 consecutive patients that presented to a single level I trauma center for surgical fixation of an acetabular fracture. Medical records were reviewed to evaluate the use of closed suction drains. The primary outcomes measures were rate of packed red blood cell (PRBC) transfusion and length of hospital stay (LOS). Secondary outcome measures were 30-day post-operative wound complication and 1-year deep infection rates. RESULTS: Of the 171 patients included in this study, 140 (82%) patients were treated with drains. There was a significant association between the use of closed suction drainage and post-operative blood transfusion rate (p = 0.002). Thirty-five patients (25%) treated with drains required a post-operative blood transfusion compared to 0% in the no drain cohort. Regarding the total number of drains used, for every additional closed suction drain that was placed beyond a single drain, the odds of receiving a blood transfusion doubled (p = 0.002). Use of closed suction drainage was associated with a significantly longer LOS (p = 0.015), and no difference in wound complication or deep infection rates. CONCLUSION: The use of closed suction drains for treatment of acetabular fractures using a K-L approach is associated with increased rates of blood transfusion and increased length of hospital stay, with no impact on surgical site infection rates. The results of this study suggest against routine drain usage in acetabular surgery.

ABSTRACT

OBJECTIVE: To examine the relationship of nutrition parameters with the modified frailty index (mFI) and postoperative complications in hip fracture patients. DESIGN: Retrospective observational cohort study. SETTING: Urban, American College of Surgeons-Verified, Level-1, Trauma Center. PATIENTS/PARTICIPANTS: Three hundred seventy-seven consecutive patients with isolated hip fractures. INTERVENTION: N/A. MAIN OUTCOME MEASURES: On admission, albumin and total lymphocyte count (TLC) levels and complication data were collected. Additionally, mFI scores were calculated. Statistical analysis was then used to analyze the association between frailty, malnutrition, and postoperative complications. RESULTS: Overall, 62.6% and 17.5% of patients were malnourished as defined by TLC of <1500 cells per cubic millimeter and albumin of <3.5 g/dL, respectively. Both TLC (P = 0.024; r = -0.12) and albumin (P < 0.001; r = -0.23) weakly correlated with frailty. Combining malnutrition and frailty revealed predictive synergy. Albumin of <3.5 g/dL and mFI of ≥0.18 in the same patient resulted in a positive predictive value of 69% and a likelihood ratio of 4 (2.15-7.43) for postoperative complications. Similarly, the combination of hypoalbuminemia and frailty resulted in a positive predictive value of 23.3% and likelihood ratio of 8.52 (P < 0.001) for mortality. CONCLUSIONS: When patients are frail and malnourished, there is a risk elevation beyond that of frailty or malnutrition in isolation. This high-risk cohort can be easily identified at admission with routine laboratory values and clinical history. There is an opportunity to improve outcomes in frail hip fracture patients because malnutrition represents a potentially modifiable risk factor. LEVEL OF EVIDENCE: Prognostic Level III.

ABSTRACT

BACKGROUND: Although preoperative templating in total hip arthroplasty is helpful to ensure appropriate component position, there is no single-view radiographic method to determine femoral anteversion (FA) preoperatively. The aim of the present study was to validate the use of radiographic measurement of FA using a modified Budin view. METHODS: This prospective study reports on 105 limbs from 65 patients. Computed tomography (CT) scans and radiographs were obtained to measure native FA. Radiographs were obtained using the modified Budin protocol with 90° flexion at the knee and 90° flexion and 30° abduction at the hip. Pearson correlation analyses, paired-samples t-test, and Bland-Altman plots were performed to assess correlation and agreement between methods. Data were grouped into subsets based on CT-derived FA in 5° intervals. Groups included all limbs, FA < 35°, FA < 30°, and FA < 25°. RESULTS: For all limbs, Bland-Altman analysis revealed a fixed bias (mean bias, -0.8°; 95% confidence interval, -1.4° to -0.2°) and showed that radiographic methods underestimated FA. Subset analyses were performed and revealed excellent correlation between CT and radiographic measurements for all subgroups (r = 0.97, P < .001). Paired-samples t-tests revealed no significant difference between methodologies for any of the subgroups. Radiographic and CT methods showed excellent agreement, and the bias between methods was within 0.5° for all subgroups. There was no fixed bias and thus no systematic difference in methods within any of the subgroup analyses. CONCLUSION: Radiographic measurement of FA using a modified Budin view is a valid and reliable technique.
