RESUMO
BACKGROUND: Numerous studies have demonstrated an increase in the number of anterior cruciate ligament (ACL) reconstruction procedures performed in pediatric patients. Despite this, most knowledge of surgical site infection rates after these procedures are based on adult studies and data is currently limited in pediatric patients. The purpose of this study was to describe and analyze the rates of infection after ACL reconstruction among pediatric patients and adolescent patients (compared with young adult patients) utilizing the MarketScan Commercial Claims and Encounters Database. METHODS: The Truven Health Analytics MarketScan Commercial Claims and Encounters database was assessed to access health care utilization data for privately insured individuals aged 5 to 30 years old. ACL reconstruction records performed between 2006 and 2018 were identified using Current Procedures Terminology (CPT) codes. International Classification of Diseases Ninth Revision (ICD-9), Tenth (ICD-10) codes and CPT codes were used to identify patients requiring treatment for infection. All patients had at least 180 days of insurance coverage after intervention. RESULTS: A total of 44,501 individuals aged below 18 years old and 63,495 individuals aged 18 to 30 years old that underwent arthroscopic ACL reconstruction were identified. There were no differences in infection rates between those below 18 years old (0.52%) and those above 18 years old (0.46%, P=0.227). However, among patients below 18 years old, patients below 15 years old had a significantly lower rate of infection at 0.37% compared with adolescents (15 to 17 y old) at 0.55% (P=0.039). Among young adults, males had higher rates of infection than females (0.52% vs. 0.37%), while no difference was observed in the pediatric and adolescent population (0.58% vs. 0.47%, P=0.109). CONCLUSION: Utilizing an insurance database, this study demonstrated that rates of infection after ACL Reconstruction in a pediatric/adolescent population are low (0.52%) and similar to rates in young adults. Infection rates after ACLR reconstruction appear to be slightly lower in patients under 15 years of age (0.37%). LEVEL OF EVIDENCE: Level III-Retrospective comparative study.

BACKGROUND: The lack of a common patient-reported outcome metric used among the orthopaedic population is a problem that has been previously identified by the American Academy of Orthopaedic Surgeons. The Patient-Reported Outcomes Measurement Information System (PROMIS) was developed by the National Institute of Health with the goal of creating a precise and efficient measurement tool for patient-reported symptoms, functioning, and health-related quality of life to be used in clinical research. A study summarizing its use in the pediatric orthopaedic population has not been previously performed. METHODS: We performed a literature search of Ovid Medline, Embase, Scopus, and the Cochrane Central Register of Controlled Trials from 2010 to August 2021. There were 1961 unique citations included after the removal of 1756 duplicates. After initial screening, 183 studies were screened under full-text review leaving a final number of 51 studies included in this scoping review. RESULTS: Pediatric PROMIS studies were grouped by body part or sub-speciality: "Hand and Upper Extremity" (25.5%, n=13), "Sports" (23.5%, n=12), "Spine" (13.7%, n=7), "Trauma" (13.7%, n=7), "General Pediatric Orthopaedics" (11.8%, n=6), "Lower Extremity" (9.8%, n=5), and "Orthopaedic Oncology" (2%, n=1). An increase in studies utilizing PROMIS was seen throughout the study period with only 3 studies published from 2013 to 2016 to 39 in 2020 and 2021 alone. The 3 most frequently used pediatric PROMIS domains were Pain Interference (76.5%, n=39/51), Mobility (60.8%, n=31/51), and Upper Extremity (54.9%, n=28/51). 64.3% (n=9/14) of the included studies which reported on the floor effects of Pain Interference exhibited a significant floor effect. In all, 77.8% (n=7/9) of the included studies which reported on ceiling effects of Upper Extremity exhibited a significant ceiling effect. CONCLUSION: The use of PROMIS increased significantly since the first publication in 2013 suggesting orthopaedic providers have increasingly utilized PROMIS in their day-to-day practice as an outcome measure. Ceiling and floor effects were prominent in several of the included domains (Pain Interference and Upper Extremity). Overall, PROMIS measures are efficient, reliable, and effective to use.

BACKGROUND: Pediatric sports medicine is a new and rapidly growing subspecialty within orthopaedic surgery. However, there is very limited literature on the practice of pediatric sports medicine in North America. Therefore, the purpose of this study was to evaluate and describe the current practice patterns of orthopaedic surgeons specializing in pediatric sports medicine. METHODS: An online survey was distributed to orthopaedic surgeons specializing in pediatric sports medicine through the Pediatric Research in Sports Medicine Society. The purpose of the survey was to characterize (1) surgeon demographics, (2) the breakdown of different joint specialization, and (3) the specific procedures for joints that the surgeons specialize in. RESULTS: Responses from 55 orthopaedic surgeons were collected and analyzed. Most respondents considered pediatric sports medicine as the primary focus of their practice (89.1%, n=49/55). The number of fellowships completed was almost evenly split between either a single fellowship (52.7%, n=29/55) or 2 or more (47.3%, n=26/55). The most common combination of fellowships was pediatric orthopaedics and adult sports medicine (32.7%, n=18/55). Most survey respondents had been in practice for <10 years (69.0%, n=38/55) and were affiliated with an academic center (61.8%, n=34/55). On average, 77.5% of the patients treated were <18 years old. The knee joint was the most specialized joint, with 98.2% (n=54/55) respondents reporting that the knee joint constituted ≥25% of their practice. The knee joint constituted a mean of 52.1% of the respondents' overall practice, followed by the shoulder (15.2%), hip (13.9%), ankle (7.5%), elbow (7.1%), and wrist (4.2%). CONCLUSIONS: Pediatric sports medicine practices are variable and have distinct practice patterns in pediatric, orthopaedic, and adult sports practices. In the current study, most surgeons are less than 10 years into practice, affiliated with academic centers, and have typically completed either 1 or 2 fellowships after residency. Surgeons were most commonly specialized in the knee joint and cared for patients <18 years old. LEVEL OF EVIDENCE: Level of evidence IV.

BACKGROUND: After treatment with in situ stabilization, slipped capital femoral epiphysis (SCFE) patients have variable degrees of deformity that can contribute to femoroacetabular impingement (FAI). To evaluate the severity of residual deformity most physicians currently use biplanar radiographs of an anteroposterior pelvis which profiles the lateral head-neck deformity and a frog lateral view which profiles the anterior head-neck deformity. However, the assessment of FAI morphology commonly relies on the 45-degree Dunn view to profile the anterolateral head-neck junction where FAI deformity is maximal. Therefore, the purpose of this study was to compare the magnitude of residual SCFE deformity detected on the frog lateral radiograph to the 45-degree Dunn radiograph. METHODS: A retrospective review of radiographic images of 50 hips (47 patients) diagnosed with SCFE at a single academic institution from 2014 to 2018 was performed. The group included 25 hips evaluated postoperatively after fixation (Group 1) and 25 hips presenting with residual symptomatic SCFE deformity after previous pinning (Group 2). The alpha angle was assessed on both the 45-degree Dunn and frog lateral views for comparison. The modified Southwick slip angle was assessed on the frog lateral view only as a measure of SCFE severity. RESULTS: The Dunn view showed the maximal residual SCFE deformity as measured by the alpha angle in 88% (44/50) of cases. Overall, the mean alpha angle (70.7 degree vs. 60.1 degree, P <0.001) was significantly larger on the Dunn view as compared with frog lateral. Subgroup analysis showed a larger alpha angle on Dunn view compared with frog lateral in both immediate postoperative and residual SCFE deformities as well: Group 1 (69.5 degree vs. 60.9 degree, P <0.001) and Group 2 (71.9 degree vs. 59.3 degree, P <0.001). CONCLUSION: In patients with SCFE, the maximal residual deformity of the proximal femur can typically be seen on the 45-degree Dunn view, rather than on the frog lateral view. Our findings suggest the 45-degree Dunn view may be beneficial part of the postoperative assessment of SCFEs to quantify the true maximal deformity present. LEVEL OF EVIDENCE: Level IV.

BACKGROUND: Plain radiographic evaluation remains the standard initial assessment of patellar instability, while 3-dimensional imaging is obtained in some patients. Merchant radiographs can demonstrate the tibial tubercle relative to the trochlear groove (TT-TG), but the determination of the TT-TG from these radiographs has been abandoned since its original description. The purpose of this study is to evaluate the utility of the TT-TG measured on Merchant radiographs for the assessment of patellar instability. METHODS: A prospective cohort study was performed of pediatric and adolescent patients aged 10 to 18 who underwent standardized Merchant radiographs, including a total of 98 knees (in 57 patients). Merchant TT-TG was measured as the distance between the center of the trochlear groove and the tibial tubercle, with both lines perpendicular to the anterior femoral condylar axis. In Part 1, the Merchant TT-TG measured by the tibial tubercle radiographic appearance was compared with the measurement utilizing a radiographic marker. In Part 2, the Merchant TT-TG was compared with the magnetic resonance imaging (MRI) TT-TG distance using bivariate linear regression analysis. TT-TG measurements were compared in patients with and without patellar instability with receiver operating characteristic curve analysis. RESULTS: The tibial tubercle was identified on Merchant radiograph in 81.7% (67/82) of knees, and there was an excellent correlation (Pearson correlation coefficient=0.85) between the Merchant TT-TG and the measurement based on marker placement. Merchant TT-TG was on average 4.5 mm less than MRI TT-TG (12.8±4.4 vs. 8.4±7.7 mm, P<0.001) and was moderately correlated (Pearson correlation coefficient=0.58, P<0.01). TT-TG distance was increased in patients with patellar instability compared with those without patellar instability on the Merchant view (10.5±6.9 vs. 2.0±5.5 mm, P<0.001) and MRI (13.9±4.4 vs. 10.5±2.9 mm, P=0.012). Merchant TT-TG also demonstrated a higher area under the curve than MRI TT-TG (0.872 vs. 0.775) in differentiating patients with and without patellar instability. CONCLUSIONS: Standardized Merchant radiographs allow for reliable assessment of the Merchant TT-TG distance when the tibial tubercle is visualized and moderately correlate with MRI TT-TG (with Merchant TT-TG on average 4.5 mm less than MRI). LEVEL OF EVIDENCE: Level III.

BACKGROUND: The utilization of meniscal repair techniques continues to evolve in an effort to maximize the rate of healing. Meniscal repair outcomes at a minimum of 5 years postoperatively appear to better represent the true failure rates. Thus, a systematic review and meta-analysis of the current literature was conducted to assess the rate of failure at a minimum of 5 years after meniscal repair. METHODS: We performed a systematic review of studies reporting the outcomes of meniscal repair at a minimum of 5 years postoperatively. A standardized search and review strategy was utilized. Failure was defined as recurrent clinical symptoms or a meniscal reintervention to repair or resect the meniscus in any capacity, as defined by the study. When reported, outcomes were assessed relative to anterior cruciate ligament (ACL) status, sex, age, and postoperative rehabilitation protocol. Meta-analyses were performed with a random-effects model. RESULTS: A total of 27 studies of 1,612 patients and 1,630 meniscal repairs were included in this review and meta-analysis. The pooled overall failure rate was 22.6%, while the failure rate of modern repairs (excluding early-generation all-inside devices) was 19.5%. Medial repairs were significantly more likely to fail compared with lateral repairs (23.9% versus 12.6%, p = 0.04). Failure rates were similar for inside-out (14.2%) and modern all-inside repairs (15.8%). Early-generation all-inside devices had a significantly higher failure rate (30.2%) compared with modern all-inside devices (15.8%, p = 0.01). There was no significant difference in meniscal failure rate between repairs with concomitant ACL reconstruction (21.2%) and repairs in ACL-intact knees (23.3%, p = 0.54). CONCLUSIONS: Modern meniscal repair had an overall failure rate of 19.5% at a minimum of 5 years postoperatively. Modern all-inside techniques appear to have improved the success rate of meniscal repair compared with use of early-generation all-inside devices. Lateral repairs were significantly more likely to be successful compared with medial repairs, while no difference was seen between patients undergoing meniscal repair with and without concomitant ACL reconstruction.

BACKGROUND: Meniscal pathology is commonly encountered in the setting of anterior cruciate ligament (ACL) rupture and is increasingly common in the pediatric and adolescent population. Studies have shown that over half of individuals presenting with ACL rupture will have concurrent meniscal pathology. PURPOSE: To define trends in the utilization of meniscal procedures (ie, meniscus repair vs partial meniscectomy) and short-term complications in pediatric and young adult patients with meniscal pathology in the setting of a concurrent ACL reconstruction. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: The IBM MarketScan Commercial Database was utilized to identify ACL reconstruction procedures performed between 2006 and 2018 for individuals aged 5 to 30 years. Annual proportions of meniscectomy and meniscal repair were analyzed, and short-term complications were compared between pediatric/adolescent patients (aged 5-17 years) and young adults (aged 18-30 years). RESULTS: An overall 40,736 records of individuals <18 years old with ACL tears were included. The pediatric/adolescent population had a significantly lower proportion of concomitant meniscal procedures (56.8%; 23,149/40,736) than the young adult population (59.7%; 33,764/56,515; P < .01). From 2006 to 2018, utilization of meniscal repair in the setting of ACL reconstruction steadily increased (20.1% to 35.1% [+15 percentage points], P < .01), while the proportion with meniscectomy decreased (34.4% to 21.3% [-13.1 percentage points], P < .01). There was no difference in rate of reoperation for repeat meniscal repair or meniscectomy in the pediatric/adolescent population for those undergoing meniscal repair versus meniscectomy within 180 days of primary surgery (1.7% [188/10,766] vs 1.5% [186/12,383]; P = .14). CONCLUSION: From 2006 to 2018, the proportion of patients receiving ACL reconstruction with concomitant meniscal repair increased (20.1% to 35.1%) while the proportion with meniscectomy decreased (34.4% to 21.3%) in the pediatric/adolescent population. Meniscal repair was not associated with a higher 180-day rate of reoperation for repeat meniscal repair or meniscectomy than meniscectomy in the setting of ACL reconstruction.

The treatment of scoliosis has been explored and debated in medicine since the first recorded texts. Scoliosis treatment has shifted over time from external modalities, such as traction and bracing, to internal stabilization techniques that leverage surgical advances. Surgical fixation constructs can generally be separated into two different modalities: dynamic vs. static constructs. For skeletally immature individuals with progressive deformities, surgical options range from traditional or magnetically controlled growing rods to vertebral body staples or tethering. For individuals who have reached skeletal maturity, many devices have been developed that provide static length constructs. Understanding the surgical options available is critical for the appropriate management of this varied patient population. With this article, we sought to provide a summary of past and present techniques and devices used in the treatment of scoliosis.
RESUMO
BACKGROUND: With the rapidly growing body of FAI literature in the last decade, improved evidence exists to support FAI surgery. However, it remains unclear how well third-party insurance company's FAI policies have adapted over time to improved evidence. The purpose of this study was (1) to compare the 2020 FAI surgery criteria of four major insurance companies utilizing a multi-center cohort of FAI patients undergoing surgery to identify rates and causes of ineligibility, and (2) to compare the rates of approval based on changes in policy from 2012 to 2020. METHODS: Four major insurance companies' coverage policies with specific criteria for the surgical treatment of FAI were applied to this population at two time points (2012 and 2020). The policies listed various combinations of age, symptom duration, radiographic signs of FAI, radiographic signs of osteoarthritis, and physical exam findings. A prospective, multi-center cohort of 712 patients (including 45.5% males and 54.5% females with a mean age of 28.7 years) undergoing surgical treatment of FAI was utilized for analysis of insurance policies. RESULTS: Based on 2020 FAI policies across 4 insurers, 22.5% (range 18.4-28.4%) of FAI patients would be deemed ineligible. In 2012, the average percent exclusion of the four companies was 23.7%. The most likely reason to be excluded was either failure to meet imaging criteria (alpha angle >50° or positive cross-over sign) [13%, n=94]) or the absence of an impingement sign (9%, n=65). Other causes of exclusion were <6-month symptom duration (6%, n=44), age <15 years (4%, n=28), or skeletally immaturity (3%, n=23). CONCLUSION: Our study shows that despite a six-year span of growing literature and updated policies, nearly 1 in 5 patients diagnosed with FAI would still potentially be denied coverage. This highlights a continued divide between surgeons and insurance companies. There is a major need for improved consensus regarding the diagnosis of FAI and appropriate indications for surgical intervention.Level of Evidence: IV.

BACKGROUND: The Patient-Reported Outcomes Measurement Information System (PROMIS) computer-adaptive testing (CAT) has been shown to be a valid and reliable means of assessing patient-reported outcomes. However, normal scores and distributions for a subset of a healthy young athletic population have not been established. PURPOSE: To establish normative PROMIS scores for the domains of Physical Function (PF-CAT), Mobility (M-CAT), Upper Extremity Function (UE-CAT), and Pain Interference (PI-CAT) and determine the frequency of floor and ceiling effects in a population of healthy collegiate athletes. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: Healthy collegiate athletes (18-23 years of age) were prospectively enrolled to complete the 4 PROMIS CAT domains. Additionally, the athletes provided information regarding their age, sex, and sport(s). Mean scores (±SD) and identification of ceiling or floor effects were calculated. Ceiling and floor effects were considered significant if >15% of the participants obtained the highest or lowest possible score on a domain. RESULTS: A total of 194 healthy athletes (mean age, 19.1 years) were included in the study: 118 (60.8%) men and 76 (39.2%) women. Mean scores were 62.9 ± 6.7 for PF-CAT, 58.2 ± 4.1 for M-CAT, 57.4 ± 5.8 for UE-CAT, and 43.2 ± 6.2 for PI-CAT. Distributions of scores for M-CAT and UE-CAT indicated strong ceiling effects by 77.3% and 66.0% of the participants, respectively. In healthy athletes, the PF-CAT differed most from the expected population-based mean score (50), with the mean being >1 SD above (62.9), without a ceiling effect observed. There were no significant sex- or age-based differences on any of the PROMIS domain scores. CONCLUSION: Healthy collegiate athletes scored nearly 1 SD from population-based means for all of the domains tested. M-CAT and UE-CAT demonstrated ceiling effects in more than two-thirds of healthy athletes, which may limit their utility in this population. The PF-CAT did not demonstrate floor or ceiling effects and demonstrated differences in a young adult athletic population from the population mean. The mean PF-CAT score of 62.9 can represent a target for return of function in injured athletes.
RESUMO
STUDY DESIGN: Retrospective cohort. OBJECTIVE: To determine if the presence of diabetes mellitus as comorbidity is associated with complications, inpatient length of stay, or direct hospital costs after minimally invasive transforaminal lumbar interbody fusion (MIS TLIF). SUMMARY OF BACKGROUND DATA: Very few studies have investigated the effect of diabetes on complications, length of stay, or costs in minimally invasive lumbar surgeries. METHODS: Patients undergoing primary, single-level MIS TLIF were retrospectively reviewed. Diabetic and nondiabetic patients were propensity matched in a 1:1 manner for age, sex, and comorbidity burden. An association between diabetic status and preoperative demographic or perioperative variables, including inpatient length of stay, was tested for using Student t test or χ analysis. Multivariate linear regression was used to test for an association between diabetic status and direct hospital costs. RESULTS: After 1:1 propensity matching, 100 patients were included in this analysis. There were no significant differences in age, sex, body mass index, smoking status, or Charlson Comorbidity Index between propensity-matched patients with and without diabetes. In regards to the length of stay, no significant differences existed between diabetic and nondiabetic groups (68.7 vs. 58.3 h, P=0.218). No other significant differences existed in other perioperative variables including operative time, intraoperative blood loss, or complication rate (P≥0.05 for each). Multivariate analysis indicated that diabetic status was not associated with differences in total direct hospital costs (US$20,428 vs. US$20,429, P=0.792) or cost subcategories after MIS TLIF (P≥0.05 for each). CONCLUSIONS: In this investigation, diabetes was not associated with postoperative complication rates, inpatient length of stay, or direct hospital costs after primary, single-level MIS TLIF. The reduced extent of operative exposure and tissue trauma in MIS TLIF may mitigate the risk of complications in diabetic patients, possibly preventing extensions in hospital stay length and associated hospital costs.

STUDY DESIGN: This was a systematic review. OBJECTIVE: The objective of this study was to review radiographic, clinical, and surgical outcomes of expandable interbody device implantation following lumbar fusion. SUMMARY OF BACKGROUND DATA: Few studies have evaluated postsurgical outcomes of expandable implants following lumbar interbody fusion. METHODS: A systematic review was performed to identify studies investigating expandable intervertebral body devices in lumbar fusion. Radiographic parameters, fusion assessments, patient-reported outcomes (PROs), complications, and revision data were recorded. A comparison of expandable and static devices was performed using a meta-analysis. RESULTS: Eleven articles were included. Postoperative improvements for each radiographic parameters for expandable versus static device implantation ranged from: lumbar lordosis, +2.0 to +5.0 degrees (expandable) versus +1.0 to +4.4 degrees (static); segmental lordosis, +1.0 to +5.2 degrees (expandable) versus+1.1 to +2.3 degrees (static); disk height, +0.82 to +4.8 mm (expandable) versus +0.26 to +6.9 mm (static); foraminal height, +0.13 to +2.8 mm (expandable) versus and +0.05 to +3.0 mm (static). Fusion rates ranged from 72.1% at 6 months to 100% at terminal follow-up. Preoperative to final follow-up improvement for the various PROs assessed were: Oswestry Disability Index, -15.4 to -56.3 (expandable) versus -13.6 to -26.3 (static); Visual Analog Scale (VAS) Back, -3.2 to -6.0 (expandable) versus -3.1 to -4.1 (static); and VAS Leg, -2.9 to -7.1 (expandable) -3.0 versus -4.8 (static). Static cages had a reported complication rate ranging from 6.0% to 16.1% and a subsidence rate of 6.0%. Expandable cages had a reported complication rate that ranged from 0.0.% to 10.0% and a subsidence rate of 5.5%-10.0%. A meta-analysis demonstrated a statistically significant difference in the PRO Oswestry Disability Index, but not VAS Back, VAS Leg, or radiographic outcomes (disk height or foraminal height). CONCLUSION: There is no clear evidence for the use of expandable interbody devices over static devices.

STUDY DESIGN: This was a retrospective study. OBJECTIVE: To determine whether an association exists between preoperative patient activation, as measured by the 10-Item Patient Activation Measure (PAM-10), and postoperative outcomes following anterior cervical discectomy and fusion (ACDF). SUMMARY OF BACKGROUND DATA: Patient motivation in maintaining positive health behaviors, a concept known as patient activation, has been established as an indicator for improvement in pain, disability, and physical function after surgery. However, no studies examine the effect of preoperative patient activation scores on outcomes following ACDF. METHODS: A prospectively maintained database was retrospectively reviewed and included patients that had a primary, 1-3 level ACDF for degenerative pathology. Patients were categorized into 3 subgroups according to their preoperative PAM-10 scores as follows: "low PAM" (bottom quartile), "moderate PAM" (second and third quartile), and "high PAM" (top quartile). Demographics and perioperative characteristics were recorded. Patient-reported outcomes including Neck Disability Index, 12-Item Short-Form Physical Component Score (SF-12 PCS), and Visual Analogue Scale (VAS) neck and arm pain were collected preoperatively and at 6-week, 3-month, 6-month, and 12-month postoperative follow-up. RESULTS: A total of 64 patients were included in this analysis. Patients were stratified by their PAM scores as follows: 25 had a low PAM score, 19 had a moderate PAM score, and 20 had a high PAM score. There was no difference in inpatient VAS pain scores or narcotic consumption. In addition, there was no difference in improvement in VAS neck pain, VAS arm pain, Neck Disability Index, and SF-12 PCS among subgroups at all postoperative follow-ups. CONCLUSIONS: Although PAM has been associated with better postoperative recovery in lumbar spine patients and other orthopedic surgeries, our investigation suggests that preoperative PAM assessments are not an effective method to predict postoperative outcomes following an ACDF.

STUDY DESIGN: A systematic review. OBJECTIVE: The aim of this study was to determine the association between study outcomes and the presence of a conflict of interest (COI) in the lumbar disc arthroplasty (LDA) literature. SUMMARY OF BACKGROUND DATA: Previous studies have evaluated the efficacy of LDA as a surgical alternative to arthrodesis. As investigators may have financial relationships with LDA device companies, it is important to consider the role of COI on study outcomes. METHODS: A systematic review was performed to identify articles reporting clinical outcomes of LDA. Any financial COIs disclosed were recorded and confirmed through Open Payments and ProPublica databases. Study outcomes were graded as favorable, unfavorable, or equivocal. Pearson Chi-squared analysis was used to determine an association between COI and study outcomes. Favorable outcomes were tested for an association with study characteristics using Poisson regression with robust error variance. RESULTS: Fifty-seven articles were included, 30 had a financial COI, while 27 did not. Ninety percent of the conflicted studies disclosed their COI in the article. Studies with United States authors were more likely to be conflicted (Pâ=â0.019). A majority of studies reported favorable outcomes for LDA (nâ=â39). Conflicted studies were more likely to report favorable outcomes than nonconflicted studies (Pâ=â0.020). Articles with COIs related to consultant fees (Pâ=â0.003), research funding (Pâ=â0.002), and stock ownership (Pâ<â0.001) were more likely to report favorable outcomes. CONCLUSION: This study highlights the importance for authors to accurately report conflicting relationships with industry. As such, orthopedic surgeons should critically evaluate study outcomes with regard to potential conflicts before recommending LDA as a surgical option to their patients. LEVEL OF EVIDENCE: 3.

STUDY DESIGN: This was a retrospective cohort study. OBJECTIVE: This study evaluates if an association exists between preoperative depression and postoperative outcomes following minimally invasive transforaminal lumbar interbody fusion (MIS TLIF). SUMMARY OF BACKGROUND DATA: Few studies have quantified preoperative depression symptoms using Patient Health Questionnaire-9 (PHQ-9) to predict postoperative outcomes after lumbar fusion, especially MIS TLIF. METHODS: A surgical database of patients undergoing primary, single-level MIS TLIF was retrospectively reviewed. Patients were stratified by predefined preoperative PHQ-9 scores: no depression (<5), mild depression (5-9), and moderate to severe depression (≥10). Inpatient pain scores and narcotics use were recorded. Oswestry Disability Index, Veterans RAND-12 Mental Component Score and Physical Component Score, and Visual Analog Scale (VAS) back and leg pain scores were collected preoperatively and at 6-week, 12-week, and 6-month follow-up. One-way analysis of variance and χ analysis determined if an association existed between PHQ-9 subgroups and baseline characteristics or perioperative outcomes. Multivariate linear regression assessed for an association between PHQ-9 and postoperative patient-reported outcomes. RESULTS: In total, 94 patients were included. Patients with higher PHQ-9 scores were younger, obese, and carried workers' compensation insurance. Higher PHQ-9 scores were associated with worse preoperative Oswestry Disability Index, Veterans RAND-12 Mental Component Score and Physical Component Score, and VAS back and leg pain scores. Patients with higher PHQ-9 reported greater inpatient VAS pain scores on postoperative day 0 and 1 and demonstrated greater hourly narcotics consumption on postoperative day 0. Furthermore, higher PHQ-9 scores exhibited less improvement in all patient-reported outcomes. CONCLUSIONS: Patients with severe depression symptoms reported greater pain, increased narcotics consumption, and less clinical improvement after MIS TLIF. Therefore, patients with greater PHQ-9 scores should be monitored more closely and may benefit from additional counseling with regard to postoperative outcomes to better manage pain control and expectations of recovery.

OBJECTIVEThis study aimed to determine if the preoperative Patient-Reported Outcomes Measurement Information System, Physical Function (PROMIS PF) score is predictive of immediate postoperative patient pain and narcotics consumption or long-term patient-reported outcomes (PROs) following minimally invasive transforaminal lumbar interbody fusion (MIS TLIF).METHODSA prospectively maintained database was retrospectively reviewed. Patients who underwent primary, single-level MIS TLIF for degenerative pathology were identified and grouped by their preoperative PROMIS PF scores: mild disability (score 40-50), moderate disability (score 30-39.9), and severe disability (score 20-29.9). Postoperative pain was quantified using the visual analog scale (VAS), and narcotics consumption was quantified using Oral Morphine Equivalents. PROMIS PF, Oswestry Disability Index (ODI), 12-Item Short-Form Health Survey, Physical Component Summary (SF-12 PCS), and VAS back and leg pain were collected preoperatively and at 6-week, 3-month, 6-month, and 12-month follow-up. Preoperative PROMIS PF subgroups were tested for an association with demographic and perioperative characteristics using 1-way ANOVA or chi-square analysis. Preoperative PROMIS PF subgroups were tested for an association with immediate postoperative pain and narcotics consumption in addition to improvements in PROMIS PF, ODI, SF-12 PCS, and VAS back and leg pain by using linear regression controlling for statistically different demographic characteristics.RESULTSA total of 130 patients were included in this analysis. Patients were grouped by their preoperative PROMIS PF scores: 15.4% had mild disability, 63.8% had moderate disability, and 20.8% had severe disability. There were no significant differences among the subgroups in terms of age, sex, smoking status, and comorbidity burden. Patients with greater disability were more likely to be obese and to have workers' compensation insurance. There were no differences among subgroups in regard to operative levels, operative time, estimated blood loss, and hospital length of stay. Patients with greater disability reported higher VAS pain scores and narcotics consumption for postoperative day 0 and postoperative day 1. Patients with greater preoperative disability demonstrated lower PROMIS PF, ODI, SF-12 PCS, and worse VAS pain scores at each postoperative time point.CONCLUSIONSPatients with worse preoperative disability, as assessed by PROMIS PF, experienced increased pain and narcotics consumption, along with less improvement in long-term PROs. The authors conclude that PROMIS PF is an efficient and accurate instrument that can quickly assess patient disability in the preoperative period and predict both short-term and long-term surgical outcomes.
