RESUMO
BACKGROUND: Patients with adolescent idiopathic scoliosis (AIS) are typically treated surgically with posterior spinal fusion (PSF) when the curve continues to progress beyond 45 to 50 degrees. In adult patients, studies have shown that preoperative psychiatric diagnoses are associated with poorer clinical outcomes after lumbar spine surgery. This study aims to address whether a preoperative mental health disorder affects outcomes in pediatric patients with AIS treated with PSF. METHODS: We conducted a retrospective study of pediatric patients with a history of AIS requiring operative treatment with PSF at a single center with a minimum of 2-year follow-up. These patients were split into 2 groups: a subset that had a mental health disorder (MHD), and a control group. The MHD subset included patients with anxiety disorder, major depressive disorder, bipolar disorder, manic disorder, obsessive-compulsive disorder, attention deficit hyperactivity disorder, and stress disorder. The 2 groups were compared using independent student t -test and χ 2 analysis. RESULTS: A total of 417 patients were included in the study. Ninety-three patients were included in the MHD group, and 324 patients were included in the control group. The mean pain score for the MHD group was greater (3.93) compared with the control group (3.34). The PCA demands during inpatient stay for the MHD group were also greater (236.7) compared with the control group (140.0). There was no significant difference in the length of stay in the hospital between the MHD group (4.7 days) and the control group (4.6 days). There was a greater number of patients in the MHD cohort (25.8%) still using narcotic pain medication at first follow-up compared with the control group (12.0%). CONCLUSION: This study suggests that patients with AIS with a preoperative mental health disorder undergoing PSF experience more pain after surgery and require more pain medication during their recovery. LEVEL OF EVIDENCE: III. This is a retrospective review of pediatric patients with adolescent idiopathic scoliosis and a preoperative mental health diagnosis and their pain management requirements during the recovery period from posterior spinal fusion.

BACKGROUND: Significant heterogeneity exists regarding patient reported outcome measures (PROMs) used in total hip (THA) and knee (TKA) arthroplasty randomized controlled trials (RCTs). This study investigates the PROMs used as primary and secondary outcomes in contemporary arthroplasty RCTs. METHODS: A literature search identified THA and TKA RCTs that were published in top ten impact factor orthopaedic journals from 2017 to 2021. Screening identified 241 trials: 76 THA, 157 TKA, and eight combined. Data were extracted to identify PROMs utilized as either primary or secondary outcomes and the time period of measurement. RESULTS: Visual Analog Scale (VAS) Pain was the most reported primary PROM in THA (9.2%) and TKA (22.9%) trials. This was followed by Numeric Rating Scale (NRS) Pain (7.9%) and the Harris Hip score (6.6%) in THA trials and NRS Pain (4.5%) and the Knee Society score (4.5%) in TKA trials. Many THA (37.0%) and TKA (52.1%) trials did not clearly specify primary outcome time points. Only pain scales were reported at time points less than one week, while various joint-specific functional outcomes were reported at later time points. As secondary outcomes, the Harris Hip score (28.9%) was most common in THA trials and the Knee Society score (26.1%) was most common in TKA trials. Indeterminate primary or secondary outcomes were reported in 18.2% of studies. CONCLUSIONS: Contemporary THA and TKA trials exhibit heterogeneity of PROMs as study outcomes after the first postoperative week. Our findings highlight the need for consensus in PROM reporting and better methodological reporting to improve the interpretability of RCT outcomes. PROSPERO REGISTRATION NUMBER: CRD42022337255.

INTRODUCTION: Patient demographics, such as sex and age, are known risk factors for undergoing revision following primary total hip arthroplasty (THA). The military population is unique because of the increased rates of primary and secondary osteoarthritis of the hip. Treatment options are limited for returning patients to their line of duty; however, THA has been shown to be an effective option. The primary purpose of this study was to evaluate and contrast the demographic differences of patients undergoing primary THA between the U.S. active duty military population and the general population. The secondary goal was to identify the proportion of primary THA performed at the MTF within the military health system (MHS). METHODS: This was an exempt study determined by the local institutional review board. A retrospective analysis of the MHS Data Repository (MDR) and the National Surgical Quality Improvement Program (NSQIP) was performed. The databases were used to identify the patients who underwent THA from January 1, 2015 to December 31, 2020. The MDR was used to identify demographics such as sex, age, setting of surgery, geographic location, previous military deployments, history of deployment-related injuries, branch of service, and rank. The NSQIP database was queried for sex and age. The median age of the population was compared using the Mann-Whitney U test and gender was compared using the Chi-square test. RESULTS: The MDR was used to evaluate 2,734 patients, whereas the NSQIP database was used to evaluate 223,832 patients. In the military population, patients who underwent THA were 87.7% male with an average age of 45 years, whereas in the general population as measured via the NSQIP database, 45.2% patients were male with an average age of 66.0 years. Comparing the two groups, we demonstrated that the military patients were significantly more likely to be younger (P < .001) and males (P < .001). Only 29.6% of primary THAs were performed within the MTF. CONCLUSIONS: Patients in the MHS are undergoing THA at a younger age and are more likely to be male compared to the general population. A significant portion of primary THAs in the MHS are also being performed at civilian institutions. These demographics may result in increased risk of revision; however, long-term studies are warranted to evaluate survivorship in this unique population.

CASE: A 15-month-old boy who was being followed for developmental dysplasia of the hip because of breech presentation was discovered to have a solitary infantile myofibroma in the left femoral neck. The patient was avoiding weight-bearing on the affected extremity; thus, stabilization of the femoral neck was performed using a proximal femur locking plate. Postoperatively, he achieved all gross motor developmental milestones. CONCLUSION: This report is the first to describe a solitary infantile myofibroma in the femoral neck and demonstrates the utility of operative stabilization of these lesions.

INTRODUCTION: Military service members experience patellar dislocations at a rate 10 times that of civilians. The purpose of this study was to determine the return to duty rate of active duty military personnel following first-time or recurrent patellar dislocation. Secondary goals were to identify patient variables and radiographic parameters associated with recurrent instability and requiring medical separation from military service. METHODS: The Military Health System Data Repository was used to identify all active-duty military personnel who sustained a patellar dislocation between 2013 and 2018. Medical records were searched for patient variables including demographics, clinical findings, radiographic findings, treatment, adverse outcomes and military disposition. Patient variables associated with recurrent instability and undergoing medical separation were determined using univariate analysis and multivariate logistic regression. A total of 207 patients met inclusion and exclusion criteria. RESULTS: Following patellar instability event, 30% of the cohort underwent surgical treatment. Fourteen per cent (29 of 207) underwent medical separation from military service. Regardless of treatment, 9% (18 of 207) experienced recurrent dislocation and 3% (6 of 207) experienced recurrent instability without dislocation. On multivariate analysis, none of the studied patient variables were associated with recurrent instability or medical separation. CONCLUSIONS: Among military personnel, return to duty rates are similar to return to sport rates in civilians. This study demonstrates no difference in risk of recurrent instability or medical separation based on anatomical factors, which is useful during shared decision-making regarding treatment options and goals.
RESUMO
INTRODUCTION: Age and sex are known demographic risk factors for requiring revision surgery following primary total knee arthroplasty (TKA). Military service members are a unique population with barriers to long-term follow up after surgery. This study aims to compare demographic data between active duty military personnel and a nationwide sample to identify differences that may impact clinical and economic outcomes. METHODS: A retrospective observational analysis was performed using the Military Health System Data Repository (MDR) and the National Surgical Quality Improvement Program (NSQIP). Databases were queried for patients undergoing primary TKA between January 1, 2015 and December 31, 2020. The MDR was queried for demographic data including age, sex, duty status, facility type, geographic region, history of prior military deployment, history of deployment-related health condition, branch of military service, and military rank. National Surgical Quality Improvement Program was queried for age and sex. Median age between populations was compared with the Mann-Whitney U test, and gender was compared with a chi-squared test. RESULTS: During the study period, 2,094 primary TKA patients were identified from the MDR, and 357,865 TKA patients were identified from the NSQIP database. Military TKA patients were 79.4% male with a median age of 49.0, and NSQIP TKA patients were 38.9% were male, with a median age of 67. Military TKA patients were significantly more likely to be male (P < .001) and younger (P < .001). CONCLUSION: Patients undergoing TKA in the military are younger and more likely to be male compared to national trends. Current evidence suggests these factors may place them at a significant revision risk in the future. The application of quality metrics based on nationwide demographics may not be applicable to military members within the Military Health System.
RESUMO
OBJECTIVE: Medial calcar buttress plating combined with lateral locked plating is biomechanically tested against isolated lateral locked plating in synthetic humeri models for the treatment of proximal humerus fractures. METHODS: Proximal humerus fractures (OTA/AO type 11-A2.1) were manufactured in 10 pairs of Sawbones humeri models (Sawbones, Pacific Research Laboratories, Vashon Island, WA). Specimen were randomly assigned and instrumented with either medial calcar buttress plating combined with lateral locked plating (CP) or isolated lateral locked plating (LP). Nondestructive torsional and axial load tests were performed to evaluate construct stiffness. Large-cycle axial tests were conducted followed by destructive ramp-to-failure tests. Cyclic stiffness was compared in both nondestructive and ultimate failure loads. Failure displacement was recorded and compared between groups. RESULTS: The addition of medial calcar buttress plating to lateral locked plating constructs significantly increased the axial ( P < 0.01) and torsional ( P < 0.01) stiffness of the construct compared with isolated lateral locked plating by 95.56% and 37.46%, respectively. All models demonstrated greater axial stiffness ( P < 0.01) after 5000 cycles of axial compression, not dependent on the fixation method. During destructive testing, the CP construct withstood 45.35% larger load ( P < 0.01) and congruently exhibited 58% less humeral head displacement ( P = 0.02) before failure when compared with the LP construct. CONCLUSION: This study demonstrates the biomechanical superiority of medial calcar buttress plating when combined with lateral locked plating as compared with isolated lateral locked plating of OTA/AO type 11-A2.1 proximal humerus in synthetic humeri models.
