Circumferential graft for elbow instability
No full textFor those patients with instability of the medial
and lateral sided of the elbow, there is a place for
a circumferential graft. This has the main advantage
of simplifying the bone tunnel creation and
graft fixation, compared to having both medialand

The many faces of brane-flux annihilation
No full text© 2015, The Author(s). Abstract: Fluxes can decay via the nucleation of Brown-Teitelboim bubbles, but when the decaying fluxes induce D-brane charges this process must be accompanied with an annihilation of D-branes. This occurs via dynamics inside the bubble wall as was well described for D3¯ branes annihilating against 3-form fluxes. In this paper we extend this to the other Dp¯ branes with p smaller than seven. Generically there are two decay channels: one for the RR flux and one for the NSNS flux. The RR channel is accompanied by brane annihilation that can be understood from the Dp¯ branes polarising into D(p + 2) branes, whereas the NSNS channel corresponds to Dp¯ branes polarising into NS5 branes or KK5 branes. We illustrate this with the decay of antibranes probing local toroidal throat geometries obtained from T-duality of the D6 solution in massive type IIA. We show that Dp¯ branes are metastable against annihilation in these backgrounds, at least at the probe level.sponsorship: We thank Iosif Bena and Ulf Danielsson for useful discussions and Marjorie Schillo and Ellen van der Woerd for many helpful comments on the manuscript.

Radial Nerve Entrapment at the Elbow
No full textRadial nerve injuries, at different levels, have been reported in swimming, tennis, golf, weight lifting, and several kinds of throwing sports. The mechanisms of injury include direct trauma and compression injuries. Radial tunnel syndrome is an uncommon pathology. However 5–8% of patients with chronic lateral epicondylitis have involvement of the posterior interosseous nerve (Celli et al. Treatment of elbow lesions. Spinger 281–297, 2008).
It is important to differentiate the two clinical syndromes related to the radial nerve.
The radial tunnel syndrome (RTS) is a compression of the radial nerve in a potential space four fingerbreadths long, located along the anterior aspect of the proximal radius, whereas the posterior interosseous nerve (PIN) syndrome relates to a compression of the PIN, with weakness of its muscles. There is weakness of extension of all of the digits, with sparing of the extensor carpi radialis brevis (ECRB).
The proximal radial nerve compression sites include fibrous bands between brachial and brachioradialis muscle anterior to the radiocapitellar joint, recurrent radial vessels (leash of Henry) at the radial neck, bands at the medial proximal edge of ECRB muscle or at the Frohse arcade (proximal edge of the superficial portion of the supinator muscle), as well as at the distal edge of the supinator muscle. The most common site includes membranous or tendinous fibers of the proximal edge of the supinator muscle. Surgery indicated if clinical symptoms of radial nerve entrapment despite conservative treatment persist
Endoscopically Assisted Decompression of Radial Nerve
No full textUsing an endoscopically assisted technique, we are able to identify all possible compression sites and where required to release them. The entry point, located 5 cm proximal of the radial humeral epicondyle between the brachioradialis/brachialis and triceps muscle, allows endoscopic exposure of the superficial and deep radial nerve branches distal of the elbow as well as the radial nerve proximal of the elbow. From this entry point, the radial nerve can be followed proximally to the spiral groove until the radial nerve disappears around the humerus. The superficial branch and the posterior interosseous nerve can be followed distally, 3–4 cm distal of the anterior elbow crease from a second incision. This forearm portal can be created by incising the skin over the transilluminated light. The scope can then be introduced at this level, and the radial nerve (superficial radial nerve and PIN) may be followed distally to the supinator muscle
Smeared antibranes polarise in AdS
No full text© 2015, The Author(s). Abstract: In the recent literature it has been questioned whether the local backreaction of antibranes in flux throats can induce a perturbative brane-flux decay. Most evidence for this can be gathered for D6 branes and Dp branes smeared over 6 − p compact directions, in line with the absence of finite temperature solutions for these cases. The solutions in the literature have flat worldvolume geometries and non-compact transversal spaces. In this paper we consider what happens when the worldvolume is AdS and the transversal space is compact. We show that in these circumstances brane polarisation smoothens out the flux singularity, which is an indication that brane-flux decay is prevented. This is consistent with the fact that the cosmological constant would be less negative after brane-flux decay. Our results extend recent results on AdS7 solutions from D6 branes to AdSp+1 solutions from Dp branes. We show that supersymmetry of the AdS solutions depend on p non-trivially.sponsorship: We would like to thank Iosif Bena, Ulf Danielsson, Alessandro Tomasiello, Daniel Thompson, Joseph Polchinski, Andrea Puhm and especially Nikolay Bobev for useful discussions.

Author Correction
No full textThe original version of this Article contained an error in Table 4, in which the coefficients of the LASSO regression model of treatment response corresponded to a version that was performed without non-coding genes. The new version of the table, which was generated during revision of the manuscript, contains the coefficients that were obtained after including potential non-coding driver genes in the model. Genomic features that became statistically significant after re-running the model were also added, which included: ‘nr of 10 kb–1Mb deletions’, ‘SBS41’, ‘Non-coding - LINC00672’, ‘Gain 7p12.3 - (PKD1L1)’, ‘Loss 4q22.1 - (CCSER1)’, and ‘Loss 18q23 - (NFATC1*)’. This has now been corrected in both the PDF and HTML versions of the Article. The original version of this Article also contained an error in the author affiliations. The affiliations of Job van Riet with Cancer Computational Biology Center, Erasmus MC Cancer Institute, Erasmus University Medical Center Rotterdam, Rotterdam, The Netherlands and Department of Urology, Erasmus MC Cancer Institute, Erasmus University Medical Center Rotterdam, Rotterdam, The Netherlands were inadvertently omitted. This has now been corrected in both the PDF and HTML versions of the Article. The original version of this Article contained an error in the Methods, section “Whole-genome sequencing; identification of somatic changes”, which incorrectly read ‘GATK BQSR and Haplotype Caller v3.4.46 were used to call somatic mutations.’ The correct version is ‘GATK BQSR and Haplotype Caller v3.4.46 and Strelka v1.0.14 were used to call somatic mutations’. This has been corrected in both the PDF and HTML versions of the Article.</p
Pattern of osteophyte distribution in primary osteoarthritis of the elbow
No full textCopyright © 2008 Journal of Shoulder and Elbow Surgery Board of Trustees Published by Mosby, Inc.The goal of this study was to look at the pattern of osteophyte distribution on a 3-dimensional computed tomography scan of patients with symptomatic osteoarthritis in the elbow. We recruited 22 consecutive patients with symptomatic osteoarthritis of the elbow for the study. Three-dimensional reconstructed anterior, posterior, medial, and lateral views of the elbow were reviewed. Ulnohumeral osteophytes were found in 21 patients (95%), and radiohumeral osteophytes were found in 13 (59%). Cadaveric and biomechanical studies suggest that the radiohumeral joint appears to be more prone to wear and stress than the ulnohumeral joint. Our study showed that the percentage of patients with ulnohumeral joint osteophytes (95%) was higher than that of radiohumeral joint (59%). Therefore, this study challenges the conventional belief that osteoarthritis starts from the radiohumeral joint and progress toward the ulnohumeral joint.Yeow Wai Lim, Roger P. van Riet, Ravi Mittal and Gregory I.
