RESUMEN
Background: During the initial coronavirus pandemic lockdown period, remote hip and knee arthroplasty care was heavily employed out of necessity. However, data on patient satisfaction with telemedicine specific to hip and knee arthroplasty patients remains unknown. Methods: All patients who had a telemedicine visit in the hip and knee arthroplasty department and completed a telemedicine satisfaction survey at a specialty hospital from April 1, 2020, to December 31, 2020, were identified. Patient satisfaction with telemedicine, gauged through a series of questions, were analyzed and evaluated over time. Independent factors associated with high satisfaction, defined as the "Top Box" response to the survey question "Likelihood of your recommending our video visit service to others," were identified. Results: Overall, 29,003 patients who had an in-person or telemedicine visit in the hip and knee arthroplasty department during the study period were identified. During the initial coronavirus pandemic lockdown period, defined as April 1, 2020-May 31, 2020, rate of overall telemedicine utilization was approximately 84%. After the initial lockdown period, the rate of overall telemedicine utilization was approximately 8% of all visits per month. Average satisfaction scores for a series of 14 questions were consistently above 4.5 out of 5. Multivariable regression revealed younger age, particularly 18-64 years old, to be the only independent factor associated with high satisfaction with telemedicine. The rate of high satisfaction remained statistically similar throughout the study period (P > .05). Conclusions: Patient satisfaction with telemedicine was consistently high in various domains and remained high throughout the study period, regardless of loosened pandemic restrictions. This technology will most likely continue to be utilized, but perhaps it should be targeted at patients younger than 65 years of age.
RESUMEN
Developmental dysplasia of the hip (DDH) often leads to characteristic acetabular dysplasia and typical femoral anomalies. There are numerous treatments for skeletally mature patients with DDH including hip arthroscopy, pelvic and femoral osteotomies, as well as total hip arthroplasty. Before proceeding to an arthroplasty procedure, it can be helpful to obtain an opinion of a hip preservation specialist to ascertain if alternative surgical treatments could contribute to the patient's care. In general, the use of robotic navigation has been associated with a higher proportion of cups placed in the Lewinnek safe zone, larger improvements in Harris Hip Scores, and no difference in overall complication rates in comparison to manual total hip arthroplasty. The use of robotic navigation allows for both 2-dimensional and 3-dimensional preoperative templating, enabling the surgeon to plan the position of the construct such that it achieves maximum bony purchase and hip stability. In complex DDH cases, surgeons can work with a biomechanics department to complete a fit check assessment, which utilizes 3-dimensional templating software to ascertain the appropriateness of the implant's geometry with the patient's anatomy. Furthermore, a 3-dimensional printed plastic model of the pelvis and/or femur can be constructed in order to complete a rehearsal procedure, which may be particularly helpful for those cases involving osteotomies. The literature on the use of robotic-assisted total hip arthroplasty in patients with DDH demonstrates improved component positioning in comparison to navigated as well as manual methods; however, studies with long-term follow-up in this patient population are lacking.
RESUMEN
PURPOSE: Pelvic tilt (PT) is important to consider when planning total hip arthroplasty (THA) due to its dynamic impact on acetabular orientation. The degree of sagittal pelvic rotation varies during functional activities and can be difficult to measure without proper imaging. The purpose of this study was to evaluate PT variation in the supine, standing, and seated positions. METHODS: A multi-centre cross-sectional study was performed that included 358 THA patients who had preo-perative PT measured from supine CT scan and standing and upright seated lateral radiographs. Supine, standing, and seated PT and associated changes between functional positions were evaluated. Anterior PT was assigned a positive value. RESULTS: In the supine position, mean PT was 4° (range, -35° to 20°), where 23% had posterior PT and 69% anterior PT. In the standing position, mean PT was 1° (range, -23° to 29°), where 40% had posterior PT and 54% anterior PT. In the seated position, mean PT was -18° (range, -43° to 47°), where 95% had posterior PT and 4% anterior PT. From standing to seated, the pelvis rotated posteriorly in 97% of cases (maximum 60°) with 16% of cases considered stiff (change ≤ 10°) and 18% of cases considered hypermobile (change ≥ 30°). CONCLUSION: Patients undergoing THA have marked PT variation in the supine, standing, and seated positions. There was wide variability in PT change from standing to seated, with 16% of patients considered stiff and 18% considered hypermobile. Functional imaging should be performed on patients prior to THA to allow for more accurate planning.

BACKGROUND: There is a lack of consensus on optimal skin closure and dressing strategies to reduce early wound complication rates after primary total hip arthroplasty (THA) and total knee arthroplasty (TKA). METHODS: All 13,271 patients at low risk for wound complications undergoing primary, unilateral THA (7,816), and TKA (5,455) for idiopathic osteoarthritis at our institution between August 2016 and July 2021 were identified. Skin closure, dressing type, and postoperative events related to wound complications were recorded during the first 30 postoperative days. RESULTS: The need for unscheduled office visits to address wound complications was more frequent after TKA than THA (2.74 versus 1.78%, P < .001), and after direct anterior versus posterior approach THA (2.94 versus 1.39%, P < .001). Patients who developed a wound complication, had a mean of 2.9 additional office visits. Compared to the use of topical adhesives, skin closure with staples had the highest risk of wound complications (odds ratio 1.8 [1.07-3.11], P = .028). Topical adhesives with polyester mesh had higher rates of allergic contact dermatitis than topical adhesives without mesh (1.4 versus 0.5%, P < .0001). CONCLUSION: Wound complications after primary THA and TKA were often self-limited but increased burden on the patient, surgeon, and care team. These data, which suggest different rates of certain complications with different skin closure strategies, can inform a surgeon on optimal closure methods in their practice. Adoption of the skin closure technique with the lowest risk of complications in our hospital would conservatively result in a reduction of 95 unscheduled office visits and save a projected $585,678 annually.

STUDY DESIGN: Retrospective cohort comparison study. OBJECTIVE: The aim was to compare perioperative complications and 30-day readmission between ambulatory and inpatient posterior cervical foraminotomy (PCF) in the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database. SUMMARY OF BACKGROUND DATA: Single-level PCF for cervical radiculopathy is increasingly being performed as an ambulatory procedure. Despite this increase, there is a lack of published literature documenting the safety of ambulatory PCF. MATERIALS AND METHODS: Patients who underwent PCF (through laminotomy or laminectomy) were identified in the 2005-2018 NSQIP database. Ambulatory procedures were defined as cases that had hospital length of stay=0 days. Inpatient procedures were defined as cases that had length of stay=1-4 days. Patient characteristics, comorbidities, and procedural variables (laminotomy or laminectomy performed) were compared between the 2 cohorts. Propensity score matched comparisons were then performed for postoperative complications and 30-day readmissions between the 2 groups. RESULTS: In total, 795 ambulatory and 1789 inpatient single-level PCF cases were identified. After matching, there were 795 ambulatory and 795 inpatient cases. Statistical analysis after propensity score matching revealed no significant difference in individual complications including 30-day readmission, thromboembolic events, wound complications, and reoperation, or aggregated complications between ambulatory versus matched inpatient procedures. Overall 30-day readmissions after ambulatory single-level PCF were noted for 2.46% of the study population, and the most common reasons were surgical site infections (46%) and pain control (15%). CONCLUSIONS: The perioperative outcomes assessed in this study support the conclusion that single-level PCF for cervical radiculopathy can be performed for correctly selected patients in the ambulatory setting without increased rates of 30-day perioperative complications or readmissions compared with inpatient procedures. LEVEL OF EVIDENCE: Level III.

INTRODUCTION: Although one of the touted benefits of the direct anterior approach (DAA) includes decreased postoperative pain, there is no consensus on the effect of surgical approach on postoperative pain and subsequent analgesic consumption. METHODS: Consecutive patients undergoing total hip arthroplasty by a single surgeon from May 2016 to March 2020 were identified. Procedures were categorized as DAA or posterior approach. Patient demographics and surgical details were assessed. Patient-reported maximum pain by postoperative day (POD), total opioid consumption during hospitalization, and whether the patient required a refill of opioid prescription within 3 months after discharge were compared between the two surgical approaches through multivariate analyses. RESULTS: A total of 611 patients were included in this study (447 DAA and 164 posterior approaches). On multivariate analyses that controlled for preoperative/intraoperative differences, patients in the DAA group had lower average maximum reported pain (0 to 10 scale) on POD #0 (6.5 versus 6.8, P = 0.034) and POD #1 (5.4 versus 6.1, P = 0.018). However, the DAA was not associated with a statistically significant reduction in total inpatient oral morphine equivalents consumed (79.8 versus 100.1, P = 0.486). Furthermore, there was no association between surgical approach and opioid prescription refill within 3 months after discharge (P = 0.864). DISCUSSION: The DAA was associated with slightly lower patient-reported pain. Furthermore, statistical analysis did not provide the necessary evidence to reject the null hypothesis, which was that there would be no difference in opioid utilization between the two approaches. Other perioperative factors may be more important to opioid use reduction than the surgical approach alone.

BACKGROUND: Early aseptic revision within 90 days after primary TKA is a devastating complication. The causes, complications, and rerevision risks of aseptic revision TKA performed during this period are poorly described. QUESTIONS/PURPOSES: (1) What is the likelihood of re-revision within 2 years after early aseptic TKA revision within 90 days compared with that of a control group of patients undergoing primary TKA? (2) What are the indications for early aseptic TKA revision within 90 days? (3) What are the differences in revision risk between different indications for early aseptic revision TKA? METHODS: Patients who underwent unilateral aseptic revision TKA within 90 days of the index procedure were identified in a national insurance claims database (PearlDiver Technologies) using administrative codes. The exclusion criteria comprised revision for infection, history of bilateral TKA, and age younger than 18 years. The PearlDiver database was selected for its large and geographically diverse patient base and the availability of outpatient follow-up data that are unavailable in other databases focused on inpatient care. A total of 481 patients met criteria for early aseptic revision TKA, with 14% (67) loss to follow-up at 2 years. This final cohort of 414 patients was compared with a control group of patients who underwent primary TKA without revision within 90 days. For the control group, 137,661 patients underwent primary TKA without early revision, with 13% (18,138) loss to follow-up at 2 years. Among these patients, 414 controls were matched using a one-to-one propensity score method; no differences in age, gender, and Charlson comorbidity index score were observed between the groups. Indications for initial revision and 2-year re-revision were recorded. The Kaplan-Meier method was used to assess survival between the early revision and control groups. RESULTS: Two-year survivorship free from additional revision surgery was lower in the early aseptic revision cohort compared with the control (78% [95% confidence interval 77% to 79%] versus 98% [95% CI 96% to 99%]; p < 0.001). Among early revisions, 10% (43 of 414) of the patients underwent re-revision for periprosthetic infection with an antibiotic spacer within 2 years. The reasons for early aseptic revision TKA were instability/dislocation (37% [153 of 414]), periprosthetic fracture (23% [96 of 414]), aseptic loosening (23% [95 of 414]), pain (11% [45 of 414]), and arthrofibrosis (6% [25 of 414]). Early revision for pain was associated with higher odds of re-revision than early revisions performed for other all other reasons (44% [20 of 45] versus 29% [100 of 344]; odds ratio 2.0 [95% CI 1.0 to 3.7]; p = 0.04). CONCLUSION: Acute early aseptic revision TKA carries a high risk of re-revision at 2 years and a high risk of subsequent periprosthetic joint infection. Patients who undergo an early revision should be carefully counseled regarding the very high risk of repeat revision and discouraged from having early revision unless the indications are absolutely clear and compelling. Early aseptic revision for pain alone carries an unacceptably high risk of repeat revision and should not be performed. Adjunctive measures for infection prophylaxis should be strongly considered. Specific interventions to reduce surgical complications in this subset of patients have not been adequately studied; additional investigation of strategies to minimize the risk of reoperation or infection is warranted. LEVEL OF EVIDENCE: Level III, therapeutic study.

BACKGROUND: the demographics, mechanisms of injury, and concurrent injuries associated with cervical, thoracic and lumbar spinal fracture and/or spinal cord injury remain poorly characterized. METHODS: Patients aged 18 and older with spinal injury between 2011 and 2015 in the National Trauma Data Bank (NTDB) were identified. Patient demographics, comorbidity burden, mechanism of injury, and associated injuries were analyzed. RESULTS: in total, 520,183 patients with acute spinal injury were identified including 216,522 cervical, 191,218 thoracic, and 220,294 lumbar. The age distributions were trimodal with peaks in incidence at around 2155 and a lesser peak around 85 years of age. The number of comorbidities increased while injury severity decreased with advancing patient age. Motor vehicle accidents (MVAs) were the most common mechanism of injury. Associated bony and internal organ injuries were common and occurred in 63% of cervical spine injury patients, 79% of thoracic spine injury patients, and 71% of lumbar spine injury patients. In all three sub-populations, there was a predominance of injuries in the local area of the primary injury. For cervical, these were rib injuries (28%), thoracic spine injuries (22%), skull fractures (20%), intracranial injuries (26%) and lung injuries (21%). For thoracic, these were rib injuries (47%), lumbar spine injuries (26%), cervical spine injuries (25%), lung injuries (35%) and intracranial injuries (24%). For lumbar, these were rib injuries (38%), thoracic spine injuries (22%), pelvic fractures (20%), lung injuries (26%) and intracranial injuries (19%). Multivariate regression analysis demonstrated that increased injury severity was strongly correlated with increased mortality, with lesser contributions from increased age and comorbidity burden. CONCLUSIONS: the current study revealed spinal fractures and/or cord injuries had high incidences of associated injuries that had a predominance of local distribution. These findings, in combination with the mortality analysis, demonstrate the importance of local targeted evaluations for associated injuries.
RESUMEN
BACKGROUND: A higher volume of primary total hip arthroplasty (THA) is starting to be performed as an outpatient procedure. However, data on appropriate patient selection for this surgical protocol is scarce. METHODS: Patients who underwent primary THA were identified in the 2012-2018 National Surgical Quality Improvement Program database. Outpatient procedure was defined as having a hospital length of stay of 0 days. The primary outcome was a readmission within the 30-day postoperative period. Risk factors for and effect of overnight hospital stay on 30-day readmission after outpatient THA were identified through multivariable models. Reasons for and timing of readmission were also identified. RESULTS: A total of 5245 outpatient THA patients and 44,171 patients who stayed 1 night were identified. The incidence of 30-day readmission after outpatient THA was 1.60% (95% confidence interval [CI] 1.26-1.94). Risk factors for 30-day readmission after outpatient THA include the following: older age relative to 18-60 years old (most notably 71-75 years old, relative risk [RR] = 2.3, 95% CI = 1.15-4.62; 76-80 years old, RR = 6.6, 95% CI = 3.55-12.43; and >80 years old, RR = 5.6, 95% CI = 2.43-12.89, P < .001) and bleeding disorders (RR = 4.5, 95% CI = 1.45-14.31, P = .010). For patients who had some of these risk factors, their risk of medically related 30-day readmission was reduced if they had stayed 1 night at the hospital (P < .05). The majority of readmissions were surgically related (62%), including wound complications (27%) and periprosthetic fractures (25%). CONCLUSION: The rate of 30-day readmission after outpatient THA was low. Patients who are at high risk for 30-day readmission after outpatient THA include those with older age and bleeding disorders. Some of these patients may benefit from an inpatient hospital stay.

BACKGROUND CONTEXT: Surgical site infections (SSIs) are medically devastating and financially costly complications after posterior spinal fusion (PSF) for neuromuscular scoliosis (NMS). Many strategies exist to reduce their occurrence. The efficacy of intraoperative antibiotics in the wound or bone graft is gaining in popularity, but this practice has not been well-studied in the PSF NMS population. PURPOSE: To assess the potential utility of intraoperative local antibiotics in patients with NMS undergoing PSF. STUDY DESIGN/SETTING: Retrospective review of prospectively collected data. PATIENT SAMPLE: Pediatric patients who underwent PSF for NMS were identified from the 2016-2018 National Surgical Quality Improvement Program (NSQIP) pediatric spinal fusion datasets. OUTCOME MEASURES: Perioperative adverse outcome variables assed included the occurrence of SSI, renal complications, and adverse hospital metrics. METHODS: Patient demographic factors, comorbidities, and the use of intraoperative antibiotics in the wound were recorded (a specifically assessed variable in the dataset). The association between the use of intraoperative antibiotics and the occurrence of adverse outcomes/infection was assessed for the entire study population and higher risk sub-populations. RESULTS: In total, 1,990 patients met the inclusion criteria, of which 87% received local antibiotics. Higher risk patients were more likely to receive local antibiotics in the wound as part of their procedure. When controlling for potentially confounding factors, the use of local antibiotics was not statistically significantly associated with any of the studied adverse outcomes for the overall study population. Subgroup analysis of higher risk patient populations (≥13 levels fused, osteotomy performed, prior deformity surgery, nonasthma lung condition) revealed a significantly decreased risk of SSI in patients undergoing ≥13 level fusions (relative risk: 0.48, 95% confidence interval: 0.25-0.91). CONCLUSIONS: With no increased overall risks and reduced SSIs in higher risk NMS patients undergoing PSF, the use of intrawound antibiotics appears to be supported by this dataset.

BACKGROUND: The etiology, complications, and rerevision risks of early aseptic revision total hip arthroplasty (THA) within 90 days are insufficiently documented. METHODS: A national insurance claims database (PearlDiver Technologies, Fort Wayne, IN) was queried for patients who underwent unilateral aseptic revision THA within 90 days of the index procedure using administrative codes. Patients who underwent revision for infection, without minimum 2-year follow-up, and younger than 18 years were excluded. This cohort was matched based on gender, age, and Charlson Comorbidity Index to a control group of patients who underwent primary THA without revision within 90 days. Two-year rerevision and 90-day complication rates were recorded. Chi-square and Fisher exact tests were used as appropriate for statistical comparison. RESULTS: Four hundred two patients met the inclusion criteria for early aseptic revision within 90 days of the index procedure and were matched to the control group. The overall 2-year rerevision rate was higher in the early revision group compared with control group (14.9% vs 2.5%, P < .001). Complications within 90 days occurred more frequently in the early revision group, including blood transfusion (10.2% vs 3.2%, P < .001), deep vein thrombosis (9.0% vs 3.2%, P = .001), and pulmonary embolism (2.74% vs 0.75%, P = .031). The most common reasons for early aseptic revision were dislocation (41.5%), fracture (38.1%), and loosening (17.4%). CONCLUSION: Early aseptic revision THA is associated with significantly higher 90-day complication rates and 2-year rerevision rates compared with a control group of primary THA without revision. The most common reasons for acute early revision were dislocation, fracture, and mechanical loosening. LEVEL OF EVIDENCE: Level III.

BACKGROUND: Geriatric femoral neck fracture is a common injury for which hemiarthroplasty (HA) or total hip arthroplasty (THA) may be considered in select patients. As prior database studies comparing these have not used propensity matching, which is a robust statistical method of controlling for potentially confounding variables, unmatched and matched methodologies are contrasted in the present study. METHODS: Patients aged ≥70 years who underwent HA or THA for hip fractures were identified from the 2012-2015 National Surgical Quality Improvement database. Propensity score 1:1 matching was performed. Differences in rates of 30-day postoperative adverse outcomes were compared using multivariate logistic regression for unmatched and matched cohorts. RESULTS: In total, 15,558 patients (14,403 HA and 1155 THA) were evaluated. Although multivariate outcomes for the unmatched populations were different for blood transfusion, mortality, minor adverse events, major adverse events, and reoperation, multivariate outcomes for matched populations only differed for blood transfusion (odds ratio 0.6 for HA vs THA, P < .001). Of note, although readmissions were similar for the two groups, patients undergoing THA had a 5.4% greater rate of perioperative readmission due to dislocation. CONCLUSION: Geriatric patients undergoing HA and THA for hip fracture were compared with and without propensity matching. Once matching was performed, the only differences in outcomes between the two groups were a lower transfusion rate among the HA group and a greater readmission rate due to dislocation among the THA group. This suggests that either procedure can be safely considered if found to be advantageous from a longer-term outcome perspective. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

BACKGROUND: Extensive research has been conducted concerning the epidemiology of fractures of the calcaneus and ankle. However, less work has characterized the population sustaining talus fractures, necessitating the analysis of a large, national sample to assess the presentation of this important injury. METHODS: The current study included adult patients from the 2011 through 2015 National Trauma Data Bank (NTDB) who had talus fractures. Modified Charlson Comorbidity Index (CCI), mechanism of injury (MOI), Injury Severity Score (ISS), and associated injuries were evaluated. RESULTS: Out of 25,615 talus fracture patients, 15,607 (61%) were males. The age distribution showed a general decline in frequency as age increased after a peak incidence at 21 years of age. As expected, CCI increased as age increased. The mechanism of injury analysis showed a decline in motor vehicle accidents (MVAs) and an increase in falls as age increased. ISS was generally higher for MVAs compared to falls and other injuries.Overall, 89% of patients with a talus fracture had an associated injury. Among associated bony injuries, non-talus lower extremity fractures were common, with ankle fractures (noted in 42.7%) and calcaneus fractures (noted in 27.8%) being the most notable. The most common associated internal organ injuries were lung (noted in 19.0%) and intracranial injuries (noted in 14.9%). CONCLUSION: This large cohort of patients with talus fractures defined the demographics of those who sustain this injury and demonstrated ankle and calcaneus fractures to be the most commonly associated injuries. Other associated orthopaedic and non-orthopaedic injuries were also defined. In fact, the incidence of associated lumbar spine fracture was similar to that seen for calcaneus fractures (14%) and nearly 1 in 5 patients had a thoracic organ injury. Clinicians need to maintain a high suspicion for such associated injuries for those who present with talus fractures. LEVEL OF EVIDENCE: Level II, retrospective study.
RESUMEN
STUDY DESIGN: This was a retrospective study of prospectively collected data. OBJECTIVE: To utilize a large national database with prospectively collected data [National Surgical Quality Improvement Program Pediatric (NSQIP-Pediatric)] to study the safety and effectiveness of antifibrinolytic use during multilevel posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS). SUMMARY OF BACKGROUND DATA: There is currently a lack of consensus and evidence regarding the safety and effectiveness of antifibrinolytic use for pediatric patients undergoing corrective surgery for AIS. MATERIALS AND METHODS: Patients who underwent multilevel PSF for AIS in the 2016 NSQIP-Pediatric database were identified. Preoperative and procedural characteristics were compared between patients who received antifibrinolytics versus those who did not. Multivariate regressions were used to compare perioperative transfusion rates and postoperative outcomes, such as rate of return to the operating room, 30-day readmission, and intensive care unit and hospital length of stay between the 2 treatment groups. RESULTS: This study included 975 patients who received antifibrinolytics and 223 patients who did not. Patients who received these agents tended to have more levels fused, osteotomies performed, and longer operative times. After controlling for these variances, there were no statistical differences in rate and volume of transfusion, rate of return to the operating room, 30-day readmission, 30-day postoperative complications, or intensive care unit or hospital length of stay between the 2 treatment groups. CONCLUSIONS: This study did not demonstrate transfusion reduction in the group that received antifibrinolytics. This finding may be, in part, secondary to nonoptimized or nonstandardized protocols for antifibrinolytic use in pediatric deformity surgery or the inability to adequately control for selection bias, as those with greater surgical invasiveness may be more likely to receive antifibrinolytics. Nonetheless, using antifibrinolytics in this population appears safe and not associated with increased perioperative complications. LEVEL OF EVIDENCE: Level III.

BACKGROUND: The last decade has seen increasing initiatives to improve health care delivery while decreasing financial expenditures, as particularly exemplified by the implementation of bundled payments for lower extremity arthroplasty, which hold the providers responsible for the both the quality and cost of these procedures. In this context, the utility of routine preoperative laboratory testing is unknown. The present study characterizes the associations, if any, between preoperative sodium, blood urea nitrogen (BUN), and creatinine values and the occurrence of general health adverse outcomes following total hip arthroplasty (THA). METHODS: Patients undergoing primary THA were identified in the 2011-2015 National Surgical Quality Improvement Program. Cases with traumatic, oncologic, or infectious indications were excluded. Preoperative levels of sodium, BUN, and creatinine were tested for associations with perioperative adverse events and adverse hospital metrics using multivariate regressions that adjusted for patient baseline characteristics. RESULTS: A total of 92,093 patients were included, of which 5.25% had an abnormal preoperative sodium level, 24.20% had an abnormal preoperative BUN level, and 11.95% had an abnormal preoperative creatinine level. Abnormal preoperative sodium levels (odds ratios: 1.23-1.50, p < 0.007) and creatinine levels (odds ratios: 1.27-1.55, p < 0.007) were associated with the occurrence of all studied adverse outcomes and abnormal preoperative BUN levels (odds ratios: 1.15-1.52, p < 0.007) were associated with the occurrence of all adverse outcomes except for hospital readmission. CONCLUSIONS: Abnormal preoperative laboratory testing is significantly associated with adverse outcomes following THA, supporting the added value of laboratory evaluation of patients before elective arthroplasty procedures. STUDY DESIGN: Clinical, Level III.

PURPOSE: To compare the efficacy, as measured through the rate of reoperation, and rates of other 30-day perioperative complications between arthrotomy and arthroscopy for the treatment of septic native shoulders in a national patient population. METHODS: Patients who were diagnosed with septic arthritis in a native shoulder and underwent irrigation and debridement through arthrotomy or arthroscopy were identified in the 2005-2016 National Surgical Quality Improvement Program database. Patient preoperative characteristics were characterized. Rate of reoperation, a proxy used to measure treatment efficacy, and other perioperative complications were compared between the 2 procedures. RESULTS: In total, 100 patients undergoing shoulder arthrotomy and 155 patients undergoing shoulder arthroscopy for septic shoulder were identified. On univariate analysis, there were no statistically significant differences in patient preoperative characteristics, operative time (60 vs. 48 minutes, P = .290), length of stay (7.5 vs. 6.6 days, P = .267), or time to reoperation (8.9 vs. 7.2 days, P = .594) between the 2 surgical groups. On multivariate analysis controlling for patient characteristics, there were no statistically significant differences in risk of reoperation (relative risk [RR] = 1.914, 99% confidence interval [CI] = 0.730-5.016, P = .083), any adverse events (RR = 1.254, 99% CI = 0.860-1.831, P = .122), minor adverse events (RR = 1.304, 99% CI = 0.558-3.047, P = .421), serious adverse events (RR = 1.306, 99% CI = 0.842-2.025, P = .118), or readmission (RR = 0.999, 99% CI = 0.441-2.261, P = .998) comparing arthrotomy with arthroscopy. CONCLUSIONS: By demonstrating similar rates of reoperation, other postoperative complications, and 30-day readmissions, the current study suggests that arthrotomy and arthroscopic surgery have similar efficacy in treating septic shoulders. However, owing to the small sample size, there is still the possibility of a type II error. LEVEL OF EVIDENCE: Level III, therapeutic retrospective comparative study.

BACKGROUND: Surgical treatment for lumbar degenerative spondylolisthesis has been shown to provide better long-term outcomes than conservative treatment. However, there is variation in surgical approaches employed by surgeons. This study investigates current surgical practice patterns and compares perioperative outcomes of 3 common surgical treatments for this pathology. METHODS: A survey was administered to surgeons who attended the Lumbar Spine Research Society (LSRS) meeting in 2014. Data were extracted from the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) from 2005 to 2014 to characterize the same responses. The 2 data sets were compared. Perioperative outcomes of those in the ACS-NSQIP posterior fusion subcohorts were characterized and compared. RESULTS: Posterior surgical approaches utilized by surgeons who responded to the LSRS survey were similar to those captured by ACS-NSQIP where 72% of those with degenerative spondylolisthesis were fused. Of those that were fused, 8% had an uninstrumented posterior fusion, 33% had an instrumented posterior fusion, and 59% had an instrumented posterior fusion with interbody. On multivariate analysis, there was no difference in risk of postoperative adverse events, readmission, or length of stay between these 3 common types of fusion. CONCLUSIONS: Practice patterns for the posterior management of lumbar degenerative spondylolisthesis were similar between LSRS survey responses and ACS-NSQIP data. The ACS-NSQIP perioperative outcome measures assessed were similar regardless of surgical technique. These findings highlight that cost-benefit considerations and longer-term outcomes have to be the measures by which surgical technique is chosen for degenerative spondylolisthesis.
RESUMEN
INTRODUCTION: Large cohort studies evaluating cardiac complications in patients undergoing spine surgery are lacking. The purpose of this study was to determine the incidence, timing, risk factors, and effect of cardiac complications in spine surgery by using a national database, the American College of Surgeons National Surgical Quality Improvement Program. METHODS: Patients who underwent spine surgery in the 2005 to 2012 National Surgical Quality Improvement Program database were identified. The primary outcome was an occurrence of cardiac arrest or myocardial infarction during the operation or the 30-day postoperative period. Risk factors for development of cardiac complications were identified using multivariate regression. The postoperative length of stay, 30-day readmission, and mortality were compared between patients who did and did not experience a cardiac complication. RESULTS: A total of 30,339 patients who underwent spine surgery were identified. The incidence of cardiac complications was 0.34% (95% confidence interval [CI], 0.27% to 0.40%). Of the cases in which a cardiac complication developed, 30% were diagnosed after discharge. Risk factors for the development of cardiac complications were greater age (most notably ≥80 years, relative risk [RR] = 5.53; 95% CI = 2.28 to 13.43; P < 0.001), insulin-dependent diabetes (RR = 2.58; 95% CI = 1.51 to 4.41; P = 0.002), preoperative anemia (RR = 2.46; 95% CI = 1.62 to 3.76; P < 0.001), and history of cardiac disorders and treatments (RR = 1.88; 95% CI = 1.16 to 3.07; P = 0.011). Development of a cardiac complication before discharge was associated with a greater length of stay (7.9 versus 2.6 days; P < 0.001), and a cardiac complication after discharge was associated with increased 30-day readmission (RR = 12.32; 95% CI = 8.17 to 18.59; P < 0.001). Development of a cardiac complication any time during the operation or 30-day postoperative period was associated with increased mortality (RR = 113.83; 95% CI = 58.72 to 220.68; P < 0.001). DISCUSSION: Perioperative cardiac complications were diagnosed in approximately 1 in 300 patients undergoing spine surgery. High-risk patients should be medically optimized and closely monitored through the perioperative period. LEVEL OF EVIDENCE: Level III.

BACKGROUND: Comorbidity indices like the modified Charlson Comorbidity Index (mCCI) and the modified Frailty Index (mFI) are commonly reported in large database outcomes research. It is unclear if they provide greater association and discriminative ability for postoperative adverse events after total shoulder arthroplasty (TSA) than simple variables. QUESTIONS/PURPOSES: Using a large research database to examine postoperative adverse events after anatomic and reverse TSA, we asked: (1) Which demographic/anthropometric variable among age, sex, and body mass index (BMI) has the best discriminative ability as measured by receiver operating characteristics (ROC)? (2) Which comorbidity index, among the American Society of Anesthesiologists (ASA) classification, the mCCI, or the mFI, has the best ROC? (3) Does a combination of a demographic/anthropometric variable and a comorbidity index provide better ROC than either variable alone? METHODS: Patients who underwent TSA from 2005 to 2015 were identified from the National Surgical Quality Improvement Program (NSQIP). This multicenter database with representative samples from more than 600 hospitals in the United States was chosen for its prospectively collected data and documented superiority over administrative databases. Of an initial 10,597 cases identified, 70 were excluded due to missing age, sex, height, weight, or being younger than 18 years of age, leaving a total of 10,527 patients in the study. Demographics, medical comorbidities, and ASA scores were collected, while BMI, mCCI and mFI were calculated for each patient. Though all required data variables were found in the NSQIP, the completeness of data elements was not determined in this study, and missing data were treated as being the null condition. Thirty-day outcomes included postoperative severe adverse events, any adverse events, extended length of stay (LOS, defined as > 3 days), and discharge to a higher level of care. ROC analysis was performed for each variable and outcome, by plotting its sensitivity against one minus the specificity. The area under the curve (AUC) was used as a measure of model discriminative ability, ranging from 0 to 1, where 1 represents a perfectly accurate test, and 0.5 indicates a test that is no better than chance. RESULTS: Among demographic/anthropometric variables, age had a higher AUC (0.587-0.727) than sex (0.520-0.628) and BMI (0.492-0.546) for all study outcomes (all p < 0.050), while ASA (0.580-0.630) and mFI (0.568-0.622) had higher AUCs than mCCI (0.532-0.570) among comorbidity indices (all p < 0.050). A combination of age and ASA had higher AUCs (0.608-0.752) than age or ASA alone for any adverse event, extended LOS, and discharge to higher level of care (all p < 0.05). Notably, for nearly all variables and outcomes, the AUCs showed fair or moderate discriminative ability at best. CONCLUSION: Despite the use of existing comorbidity indices adapted to large databases such as the NSQIP, they provide no greater association with adverse events after TSA than simple variables such as age and ASA status, which have only fair associations themselves. Based on database-specific coding patterns, the development of database- or NSQIP-specific indices may improve their ability to provide preoperative risk stratification. LEVEL OF EVIDENCE: Level III, diagnostic study.

BACKGROUND CONTEXT: Posterior lumbar fusion (PLF) is a commonly performed procedure. The evolution of bundled payment plans is beginning to require physicians to more closely consider patient outcomes up to 90 days after an operation. Current quality metrics and other databases often consider only 30 postoperative days. The relatively new Healthcare Cost and Utilization Project Nationwide Readmissions Database (HCUP-NRD) tracks patient-linked hospital admissions data for up to one calendar year. PURPOSE: To identify readmission rates within 90 days of discharge following PLF and to put this in context of 30 day readmission and baseline readmission rates. STUDY DESIGN: Retrospective study of patients in the HCUP-NRD. PATIENT SAMPLE: Any patient undergoing PLF performed in the first 9 months of 2013 were identified in the HCUP-NRD. OUTCOME MEASURES: Readmission patterns up to a full calendar year after discharge. METHODS: PLFs performed in the first 9 months of 2013 were identified in the HCUP-NRD. Patient demographics and readmissions were tracked for 90 days after discharge. To estimate the average admission rate in an untreated population, the average daily admission rate in the last quarter of the year was calculated for a subset of PLF patients who had their operation in the first quarter of the year. This study was deemed exempt by the institution's Human Investigation Committee. RESULTS: Of 26,727 PLFs, 1,580 patients (5.91%) were readmitted within 30 days of discharge and 2,603 patients (9.74%) were readmitted within 90 days of discharge. Of all readmissions within 90 days, 54.56% occurred in the first 30 days. However, if only counting readmissions above the baseline admission rate of a matched population from the 4th quarter of the year (0.08% of population/day), 89.78% of 90 day readmissions occurred within the first 30 days. CONCLUSIONS: The current study delineates readmission rates after PLF and puts this in the context of 30-day readmission rates and baseline readmission rates for those undergoing PLF. These results are important for patient counseling, planning, and preparing for potential bundled payments in spine surgery.
