We make all code and models freely available alongside a demonstration of the web interface.Dynamic nuclear polarization-enhanced (DNP) magic angle spinning (MAS) NMR of biological systems is a rapidly growing field. Large signal enhancements make the technique particularly attractive for signal-limited cases, such as studies of complex biological assemblies or at natural isotopic abundance. However, spectral resolution is considerably reduced compared to ambient-temperature non-DNP spectra. Herein, we report a systematic investigation into sensitivity and resolution of 1D and 2D 13C-detected DNP MAS NMR experiments on HIV-1 CA tubular assemblies. We show that the magnitude and sign of signal enhancement as well as the homogeneous line width are strongly dependent on the biradical concentration, the dominant polarization transfer pathway, and the enhancement buildup time. Our findings provide guidance for optimal choice of sample preparation and experimental conditions in DNP experiments.Recently, Bayesian estimation coupled with finite element modeling has been demonstrated as a viable tool for estimating vocal fold material properties from kinematic information obtained via high-speed video recordings. In this article, the sensitivity of the parameter estimations to the employed fluid model is explored by considering Bernoulli and one-dimensional viscous fluid flow models. Simulation results indicate that prescribing an ad hoc separation location for the Bernoulli flow model can lead to large estimate biases, whereas including the separation location as an estimated parameter leads to results comparable to that of the viscous fluid flow model.This case report documents a rare inversion of a closed metacarpal head fracture in the setting of polytrauma. Although rare, hemispherical articular bones can fracture and rotate 180°. Because of the symmetry of the bone and the rarity of an inverted, metacarpal head fracture, a delay in diagnosis and subsequent treatment can occur, which can lead to a poor outcome. This is particularly true in the setting of polytrauma. A 38-year-old male, polytrauma patient presented to the emergency department (ED) after falling off a bridge and being struck by an oncoming vehicle. He presented with multiple surgical fractures of the upper and lower extremities as well as his pelvis. Three days after he was brought to the ED, x-rays were performed of his painful left hand, which revealed an extra-articular third metacarpal head fracture, for which he underwent open reduction of the closed fracture. Both collateral ligaments were intact and the head fragment had inverted within the constraints of these ligaments. Some of the ligament and capsular tissue remained attached to the head fragment along the radial and ulnar margins but was otherwise entirely covered with cartilage. The reduction maneuver was difficult but after the reduction was achieved, the fracture appeared stable and no internal fixation was used. Post reduction, the injury was splinted for 2 weeks and then early motion was allowed. The fracture has since healed, and the patient has attained near-full function of the finger and joint.
Loeys-Dietz syndrome (LDS) is a genetic syndrome caused by mutations in transforming growth factor beta receptors (TGFBR) 1 and 2. It can manifest with craniofacial, musculoskeletal, cognitive abnormalities, and vascular pathologies including early onset aortic root aneurysms, extensive aortic dissections, and TAAA. Open repair is considered the gold standard treatment but carries morbidity risks, especially in patients with multiple previous aortic procedures. Endovascular treatment is associated with treatment failure when used in the native aorta, because of inherent wall weakness precluding seal. This case report adds to the available literature on hybrid treatment of LDS associated aortic pathologies.

This is the report of staged hybrid TAAA treatment in a 24 year old male patient with multiple previous aortic procedures via sternotomy and thoracotomy. Retrograde infrarenal aortic visceral debranching was performed using 14mm by 7mm bifurcated Dacron grafts. These emerged from the limbs of an 18mm byndovascular seal in surgical grafts. Short term surveillance showed no complications. Limitations to making recommendations include lack of long term follow up.
The aim of our study is to prove the validity and reliability of the Greek translated version of the self-report section of the American Shoulder and Elbow Surgeons (ASES) questionnaire.

A total of 108 patients with various shoulder disorders were evaluated at two different orthopediccenters. All patients answered the Greek ASES questionnaire as well as the previously validated Greek version of the Disability Arm Shoulder and Hand score. Three days after the first evaluation, a subgroup of 40 individuals was randomly selected to complete again the Greek ASES text to prove its reliability, after the test-retest procedure. Reliability was tested with Cronbach's alpha, stability by calculating the intraclass correlation coefficient and by Blant Altman plot and structural validity with the confirmatory factor analysis.

The internal consistency of the ASES functional score and the ASES total score was 0.925 and 0.750 respectively. The intraclass correlation coefficient between initial assessment and reassessment of the ASES functional and total score was 0.951 and 0.938 (
< .001), respectively. The correlation coefficientscorrelation between the ASES functional and total scores with DASH total score were -0.881 and -0.759 (
< .001), respectively.

The Greek ASES version proved to be equivalent to the English original version in evaluating different shoulder disorders in the Greek population.

Most patients have successful outcomes with minimal limitations after distal biceps repair, but a minority continues experiencing functional constraints. We hypothesize that low scores on a validated mental health measure correlate with worse patient-reported outcomes and increased difficulty with return to work and sport.

We conducted a retrospective review of a consecutive series of patients who underwent distal biceps repair with a single-incision cortical button technique and immediate mobilization. check details Patient-reported outcome data were available at 1 year or later for 33 (85%) patients. The primary outcomes were American Shoulder and Elbow Surgeons-Elbow (ASES-E) score, Single Assessment Numeric Evaluation score, Visual Analog Scale for pain, Disabilities of the Arm, Shoulder and Hand Score (QuickDASH), and Veterans RAND 12 (VR-12) quality-of-life assessment.

All patients were male, with a median age of 49 years (range, 28-65). None had reruptures, and 1 (3%) had superficial wound dehiscence that heal
=.026). Most patients (17 of 24, 71%) with MCS≥50 had a perfect score of 36 on the ASES-E functional outcome score, compared with only 22% (2 of 9) among patients with MCS<50.

Patients who undergo distal biceps repair show excellent functional patient-reported outcomes at 1-year and later follow-up. Lower scores on the VR-12 MCS are associated with worse patient-reported outcome scores and difficulty with return to work and sporting activities.

Elbow fracture dislocations represent difficult injuries to treat, with a high percentage of complications. Classically, they are divided into posterolateral, posteromedial and transulnar pattern. It is essential to distinguish them to guide intraoperative treatment to achieve an anatomic and stable reduction that allows early mobility.

A retrospective study of 89 adult patients diagnosed with elbow fracture dislocations who underwent a standardized surgery between 2013 and 2018 with a minimum follow-up of 12 months. Demographic data, characteristics of the injury, and associated procedures were collected. Patients were evaluated with functional scores (Mayo elbow performance score/Broberg and Morrey score) and ranges of movement at the end of the follow-up.

The mean age was 41 ± 12 years, mostly men (82%), with an average follow-up of 29 months. We present 42 patients with posterolateral fracture dislocation (47%), 21 posteromedial (24%) and 26 transulnar (29%). The average range of motion at the end of follow-up was-12 ± 11° extension, 124 ± 20° flexion, 76 ± 16° pronation, and 73 ± 20° supination, with a Mayo elbow performance score of 88.7 ± 12 points and 87.2 ± 12 points in the Broberg and Morrey scale. Reoperation rate was 23%, with no infection or heterotopic ossification cases. Transulnar fracture dislocations have significantly worse extension and supination. As per the functional result (Mayo elbow performance score/Broberg and Morrey scale), there are no significant differences between the different patterns.

Proper injury pattern recognition and a standardized surgical management lead to a stable joint and good results in range of motion. Functional results are encouraging at least at short term, despite the high reoperations rate.

Based on the controversy over whether the extensor tendon is the only lesion of lateral epicondylitis of the elbow and numerous reports of concomitant lateral collateral ligament involvement, potential damage to the lateral collateral ligament complex should be considered for the treatment.

About 25 elbows in 23 patients (débridement group) and 22 elbows in 20 patients (reconstruction group) who were diagnosed with lateral epicondylitis and had an average of 22 months of symptoms revealing anatomical lesion on MRI were included. The capitellum-sublime tubercle-radial head (CSR) angle was measured on both sides preoperatively, and the visual analog scale (VAS) and Mayo elbow performance score (MEPS) were measured over 12 months, postoperatively.

The initial preoperative mean VAS was statistically significant with 4.6 in the débridement group and 6.5 in the reconstruction group (
<.05). Postoperative VAS was continuously decreased in both groups with no significant difference at each assessment periodprevious surgery.
In the surgical treatment of recalcitrant lateral epicondylitis, lateral ulnar collateral ligament reconstruction added to the débridement of extensor origin may provide better results for the patients with suspicious lateral ligament insufficiency or failed previous surgery.
Coronal shear fractures of the distal humerus are rare injuries, and fragmentation of the capitellum and trochlea with posterior comminution is challenging for surgeons. We retrospectively evaluated the functional outcomes of patients with coronal shear fractures managed with open reduction and internal fixation, focusing on the number of trochlea fragments in Dubberley type 3B fractures.

The functional outcomes of 25 patients, including 8 patients with type 3B fractures, with a mean age (and standard deviation) of 57±20 years, were evaluated at a mean follow-up duration of 15±9 months. Type 3B fractures were classified into two groups those with two trochlea fragments or less group (group A) and those with three or more fragments (group B). Patient outcomes were assessed with clinical and radiographic examination, range of motion, and the Mayo Elbow Performance scale (MEPS).

Two patients with type 3B in group B experienced nonunion, and two patients with type 3B in group A and 1 patient with type 1B demonstrated avascular necrosis on radiographs.
