Authors: Neuwirth Alexander L. , Stitzlein Russell N. , Neuwirth Madalyn G. , Kelz Rachel K. , Mehta Samir 
Published: January 2018

Background:
Future generations of orthopaedic surgeons must continue to be trained in the surgical management of hip fractures. This study assesses the effect of resident participation on outcomes for the treatment of intertrochanteric hip fractures.

Methods:
The National Surgical Quality Improvement Program (NSQIP) database (2010 to 2013) was queried for intertrochanteric hip fractures (International Classification of Diseases, 9th Revision, Clinical Modification [ICD-9-CM] code 820.21) treated with either extramedullary (Current Procedural Terminology [CPT] code 27244) or intramedullary (CPT code 27245) fixation. Demographic variables, including resident participation, as well as primary (death and serious morbidity) and secondary outcome variables were extracted for analysis. Univariate, propensity score-matched, and multivariate logistic regression analyses were performed to evaluate outcome variables.

Results:
Data on resident participation were available for 1,764 cases (21.0%). Univariate analyses for all intertrochanteric hip fractures demonstrated no significant difference in 30-day mortality (6.3% versus 7.8%; p = 0.264) or serious morbidity (44.9% versus 43.2%; p = 0.506) between the groups with and without resident participation. Multivariate and propensity score-matched analyses gave similar results. Resident involvement was associated with prolonged operating-room time, length of stay, and time to discharge when a prolonged case was defined as one above the 90th percentile for time parameters.

Conclusions:
Resident participation was not associated with an increase in morbidity or mortality but was associated with an increase in time-related secondary outcome measures. While attending surgeon supervision is necessary, residents can and should be involved in the care of these patients without concern that resident involvement negatively impacts perioperative morbidity and mortality.

Published: January 2018

Background:
Microfracture is commonly performed for cartilage repair but usually results in fibrocartilage. Microfracture augmented by autologous bone marrow concentrate (BMC) was previously shown to yield structurally superior cartilage repairs in an equine model compared with microfracture alone. The current study was performed to test the hypothesis that autologous BMC without concomitant microfracture improves cartilage repair compared with microfracture alone.

Methods:
Autologous sternal bone marrow aspirate (BMA) was concentrated using a commercial system. Cells from BMC were evaluated for chondrogenic potential in vitro and in vivo. Bilateral full-thickness chondral defects (15-mm diameter) were created on the midlateral trochlear ridge in 8 horses. Paired defects were randomly assigned to treatment with BMC without concomitant microfracture, or to microfracture alone. The repairs were evaluated at 1 year by in vitro assessment, arthroscopy, morphological magnetic resonance imaging (MRI), quantitative T2-weighted and ultrashort echo time enhanced T2* (UTE-T2*) MRI mapping, and histological assessment.

Results:
Culture-expanded but not freshly isolated cells from BMA and BMC underwent cartilage differentiation in vitro. In vivo, cartilage repairs in both groups were fibrous to fibrocartilaginous at 1 year of follow-up, with no differences observed between BMC and microfracture by arthroscopy, T2 and UTE-T2* MRI values, and histological assessment (p > 0.05). Morphological MRI showed subchondral bone changes not observed by arthroscopy and improved overall outcomes for the BMC repairs (p = 0.03). Differences in repair tissue UTE-T2* texture features were observed between the treatment groups (p < 0.05).

Conclusions:
When BMC was applied directly to critical-sized, full-thickness chondral defects in an equine model, the cartilage repair results were similar to those of microfracture. Our data suggest that, given the few mesenchymal stem cells in minimally manipulated BMC, other mechanisms such as paracrine, anti-inflammatory, or immunomodulatory effects may have been responsible for tissue regeneration in a previous study in which BMC was applied to microfractured repairs. While our conclusions are limited by small numbers, the better MRI outcomes for the BMC repairs may have been related to reduced surgical trauma to the subchondral bone.

Clinical Relevance:
MRI provides important information on chondral defect subsurface repair organization and subchondral bone structure that is not well assessed by arthroscopy.
The Effect of Alternative Bearing Surfaces on the Risk of Revision Due to Infection in Minimally Stabilized Total Knee Replacement
Authors: Vertullo Christopher J. , Lewis Peter L. , Peng Yi , Graves Stephen E. , de Steiger Richard N. 
Published: January 2018

Background:
The effect of alternative bearing materials on the risk of revision due to infection after total knee replacement remains uncertain. By reducing the immunomodulating polyethylene wear-particle burden and with different substrate bacterial adhesion properties, Oxinium oxidized zirconium and cross-linked polyethylene (XLPE) could alter infection risk. The purpose of the current study was to analyze the risk of revision for infection in 3 comparisons of bearing combinations.

Methods:
To evaluate the risk of revision for infection with XLPE, cobalt-chromium (CoCr) on XLPE was compared with CoCr on non-cross-linked polyethylene (NXLPE). To evaluate Oxinium, Oxinium-NXLPE was compared with CoCr-NXLPE, and to evaluate the possibility of an additional beneficial effect of Oxinium on XLPE, Oxinium-XLPE was compared with CoCr-XLPE. The cumulative percent revision (CPR) and hazard ratio (HR) for revision for infection in primary total knee replacement for osteoarthritis were determined from registry data from September 1, 1999, to December 31, 2015. Revisions within 6 months following the primary surgery were censored from the analysis, while procedures with posterior stabilized or fully stabilized total knee replacements as well as prostheses with a known higher risk of revision were excluded. Analyses were stratified by age, sex, and fixation type.

Results:
Of the 326,603 included primary total knee replacements, 1,511 (0.46%) were revised for infection. The risk of revision for infection was lower for CoCr-XLPE compared with CoCr-NXLPE (HR = 0.74; 95% confidence interval [CI] = 0.65 to 0.84; p < 0.001). This effect was apparent for both male and female patients overall, all fixation types, antibiotic cement use, those <65 years of age, and male patients ≥65 years of age. However, for female patients ≥65 years of age, there was no difference. Overall, Oxinium-NXLPE had the same revision risk as CoCr-NXLPE regardless of fixation; however, for cemented fixation, subanalysis showed a lower risk for Oxinium-NXLPE compared with CoCr-NXLPE (HR = 0.69; 95% CI = 0.51 to 0.94; p = 0.018). Oxinium-XLPE had the same revision risk for infection as CoCr-XLPE overall, among male patients, and when cemented fixation had been used.

Conclusions:
In this registry analysis, CoCr-XLPE had a 26% lower risk of revision for infection than CoCr-NXLPE, suggesting a reduction of wear particle-induced immunomodulation with XLPE. Oxinium-XLPE had the same risk as CoCr-XLPE. Overall, Oxinium did not reduce the infection risk.

Core Ideas
The confidence interval (CI) of Pearson’s correlation coefficient (r) was investigated.Confidence interval width is inversely proportional to r and sample size (n).It is recommended to use 1000 or more bootstrap replicates in order to not underestimate CI width (CIw).A model to estimate CIw as a function of n and r is proposed.
The nonparametric bootstrap percentile method has been widely used to estimate confidence intervals (CI) for Pearson’s product‐moment correlation coefficient (r). However, because most studies provide results for specific crops and pre‐stablished CIs, an innovative approach to CI estimation is needed. The aim of this study was to propose a model that predicts CI width (CIw) as a function of the sample size (n) and the strength of association among traits. Additionally, we also investigated the extent to which the number of bootstrap replicates (BRs) influences CI estimation. Seventy‐eight different r magnitudes from a maize field experiment were used. The 95% CI half‐width for each trait combination was estimated based on 991 different sample sizes and seven different numbers of BRs. A simple nonlinear model with n and r as predictors is proposed for estimating the CIw: , where δ, β0, and β1 are the model coefficients. Based on our data, the fitted model was: . This model exhibited excellent goodness of fit (R2 = 0.988; root mean square error [RMSE] = 0.011). Considering an assumed magnitude of association (r), the n for a desired CIw can then be calculated as: . We also recommend using ≥1000 BRs, to prevent underestimating CIw. Finally, we present an intuitive table that provides previously estimated n for 9 levels of half‐widths for 95% CIs (0.05, 0.1,... 0.45) and 19 magnitudes for r (0.05, 0.10,..., 0.95).
A Novel and Facile Method for Characterizing Shrinkage Geometry along the Granitic Soil Profile

Published: January 2018

Core Ideas
A simple and facile approach was proposed for measuring the anisotropic shrinkage.
Subsidence was dominant for soils in the loose and aggregated structure.
Horizontal shrinkage was predominant for soils with the horizontal arrangement of plate particles
The shrinkage behavior of granite soils was controlled by clay content and pore structure.
Soil volume change resulting from frequent drying–wetting cycles leads to severe erosion and landslides in granite regions. Limited attempts have been made to investigate the shrinkage geometry of these soils. Here, a new method was proposed for characterizing soil shrinkage behavior by testing cylindrical specimens of undisturbed granitic soils sampled separately in vertical and horizontal directions at the pedogenic layers (i.e., surface [L1], lateritic [L2 and L3], sandy [L4], and detritus [L5] layers). For L1, the coefficient of linear extensibility (COLE) was larger in the vertical than in the horizontal direction, whereas it was the opposite for L2 and L3. For L4 and L5, the COLE showed no significant differences between the two directions. A modified van Genuchten equation fitted well with the COLE curves (p < 0.01). The shrinkage potential decreased in the order of L3 > L2 > L1, L4 > L5. Subsidence was dominant for the L1 soil due to the loose‐aggregated structure, whereas cracking was dominant in the lateritic layer soils due to the horizontal arrangement of clay particles. The shrinkage geometry for L4 and L5 was largely determined by soil structure inherited from the configuration of granite rock. The shrinkage behavior of granite soils was controlled by clay content and pore structure. This new method of measuring shrinkage geometry is accurate, low cost, nondestructive, and labor saving but remains to be improved and validated on a wide range of soil types.
Interpreting TDR Signal Propagation through Soils with Distinct Layers of Nonaqueous‐Phase Liquid and Water Content
Authors: Comegna A. , Coppola A. , Dragonetti G. , Severino G. , Sommella A. 
Published: January 2018

Core Ideas
The TDR response in the presence of NAPL transport was investigated in a homogeneous soil.
The experimental framework was designed to simulate sharp NAPL fronts that moved in the soil.
The TDR waveforms were analyzed to deduce the influence of NAPLs on TDR signal propagation.
A general procedure to determine the location of an NAPL‐contaminated front was developed.
Several studies have demonstrated that time‐domain reflectometry (TDR) has an enormous potential to detect and monitor nonaqueous‐phase liquids (NAPLs) in uniformly contaminated soils with reference to different‐textured soils and under different saturation conditions. Few attempts have been proposed to describe NAPL distribution by using TDR when a contaminated front propagates through a soil. In this study, the TDR response in the presence of NAPL‐contaminant transport processes was investigated in a homogeneous soil under confined conditions with a series of laboratory‐controlled tests. The laboratory procedure involved measurements of dielectric permittivity (εb) and electrical conductivity (ECb) and the acquisition of the reflected TDR waveforms. The experimental framework was designed to simulate sharp NAPL fronts that moved in the soil columns and generated zones of contrasting permittivity. During the experiments, different initial conditions were assumed, as well as different degrees of contamination, by varying the volumetric water (θw) and NAPL (θNAPL) contents. The acquired TDR waveforms were systematically analyzed to deduce the influence of NAPLs on TDR signal propagation. A general procedure to determine the location of an NAPL‐contaminated front within a soil column was developed. Equipment calibration, measurement accuracy, and error sources were investigated in relation to the experimental procedure setup and the column preparation conditions. The results show that there may be some difficulties when interpreting TDR signals to locate the NAPL front for two main reasons: first, the expected additional reflection at the interface is not always distinguishable; second, there may be problems even locating both the first peak and the reflection point at the end of the TDR probe, especially when the signal shifts from a low to a high impedance layer. The suggested methodology provides a tool to overcome such intrinsic difficulties in NAPL front detection during the propagation of the contaminant.
