Abstract

Background: Shoulder arthroscopy is one of the most commonly performed orthopaedic procedures used to treat a variety of conditions, with >500,000 procedures performed each year. Purpose: To systematically review the randomized controlled trials (RCTs) on pain control after shoulder arthroscopy in the acute postoperative setting and to ascertain the best available evidence in managing pain after shoulder arthroscopy to optimize patient outcomes. Study Design: Systematic review and meta-analysis. Methods: A systematic review of the literature was performed based on the PRISMA (Preferred Reporting Items for Systematic Meta-Analyses) guidelines. Studies were included if they were RCTs evaluating interventions to reduce postoperative pain after shoulder arthroscopy: nerve blocks, nerve block adjuncts, subacromial injections, patient-controlled analgesia, oral medications, or other modalities. Meta-analyses and network meta-analyses were performed where appropriate. Results: Our study included 83 RCTs. Across 40 studies, peripheral nerve blocks were found to significantly reduce postoperative pain and opioid use, but there was no significant difference among the variable nerve blocks in the network meta-analysis. However, continuous interscalene block did have the highest P-score at most time points. Nerve block adjuncts were consistently shown across 18 studies to prolong the nerve block time and reduce pain. Preoperative administration was shown to significantly reduce postoperative pain scores ( P < .05). No benefit was found in any of the studies evaluating subacromial infusions. Conclusion: Continuous interscalene block resulted in the lowest pain levels at most time points, although this was not significantly different when compared with the other nerve blocks. Additionally, nerve block adjuncts may prolong the postoperative block time and improve pain control. There is promising evidence for some oral medications and newer modalities to control pain and reduce opioid use. However, we found no evidence to support the use of subacromial infusions or patient-controlled analgesia.

Abstract

STUDY DESIGN Systematic literature review. OBJECTIVE The aim of this study was to systematically review the current evidence in the literature on thoracic discectomies, to compare the clinical outcomes, and to determine whether there is evidence to support the use of either the anterior or posterior approach. SUMMARY OF BACKGROUND DATA Thoracic disc herniations (TDHs) often present with myelopathy, radiculopathy, or a combination of both. The posterior approach for thoracic discectomy has been associated with a lower complication rate, but no systematic review exists comparing the clinical outcomes. METHODS MEDLINE, EMBASE, and The Cochrane Library databases were searched in accordance with the PRISMA guidelines for studies performing an anterior or posterior thoracic discectomy. The methodological quality was assessed using the Methodological Index for Non-Randomized Studies checklist. The reported clinical outcomes were evaluated using risk ratio, with a P

Abstract

Rotator cuff tears are a common pathology, with an increasing number of repairs being performed arthroscopically. The purpose of this study was to systematically review the results in the current meta-analyses on arthroscopic rotator cuff repair, looking specifically at double-row repair compared with single-row repair, at whether platelet-rich plasma should be used adjunctively at the time of the surgical procedure, and at the effects of early-motion compared with late-motion rehabilitation postoperatively.MEDLINE, Embase, and the Cochrane Library were screened for meta-analyses on arthroscopic rotator cuff repair. The levels and quality of the evidence were assessed, and the clinical outcomes were evaluated. A significant result was defined as p0.05.Twenty-four meta-analyses were identified, with 10 meta-analyses on double-row repair compared with single-row repair, 7 meta-analyses on platelet-rich plasma compared with a control, and 7 meta-analyses on early motion compared with late motion. Studies found a significant result in terms of reduced retear rates and/or increased tendon-healing rate for double-row repair (6 of 10 studies; p0.05), without a clinically important improvement in functional outcomes (0 of 10 studies). There was a favorable outcome when using platelet-rich plasma in small-to-medium tears in terms of a reduced rate of retear (4 of 4 studies; p0.05). However, in the 1 study in which platelet-rich plasma was stratified into pure platelet-rich plasma and platelet-rich fibrin matrix preparation, there was a significantly lower retear rate for tears of all sizes with platelet-rich plasma and not with platelet-rich fibrin (p0.05). Range of motion was shown to be significantly better with early motion (5 of 6 studies; p0.05) in the majority of the meta-analyses, without an increased risk of retear (6 of 6 studies; p0.05).The highest Level of Evidence and the highest-quality studies all supported the use of double-row repair, adjunctive platelet-rich plasma, and early-motion rehabilitation postoperatively in arthroscopic rotator cuff repair.Therapeutic Level III.

Abstract

We present a measurement of semi-inclusive spin asymmetries for positively and negatively charged hadrons from deep inelastic scattering of polarised muons on polarised protons and deuterons in the range $0.003$1 GeV$^2$. Compared to our previous publication on this subject, with the new data the statistical errors have been reduced by nearly a factor of two. From these asymmetries and our inclusive spin asymmetries we determine the polarised quark distributions of valence quarks and non-strange sea quarks at $Q^2$=10 GeV$^2$. The polarised $u$ valence quark distribution, $\Delta u_v(x)$, is positive and the polarisation increases with $x$. The polarised $d$ valence quark distribution, $\Delta d_v(x)$, is negative and the non-strange sea distribution, $\Delta \bar q(x)$, is consistent with zero over the measured range of $x$. We find for the first moments $\int_0^1 \Delta u_v(x) dx = 0.77 \pm 0.10 \pm 0.08$, $\int_0^1 \Delta d_v(x) dx = -0.52 \pm 0.14 \pm 0.09$ and $\int_0^1 \Delta \bar q(x) dx= 0.01 \pm 0.04 \pm 0.03$, where we assumed $\Delta \bar u(x) = \Delta \bar d(x)$. We also determine for the first time the second moments of the valence distributions $\int_0^1 x \Delta q_v(x) dx$., Comment: 17 pages

Abstract

We present a new measurement of the virtual photon proton asymmetry $A_1^{\rm p}$ from deep inelastic scattering of polarized muons on polarized protons in the kinematic range $0.0008 < x < 0.7$ and $0.2 < Q^{2} < 100$ GeV$^{2}$. With this, the statistical uncertainty of our measurement has improved by a factor of $2$ compared to our previous measurements. The spin-dependent structure function $g_{1}^{\rm p}$ is determined for the data with $Q^{2} > 1$ GeV$^{2}$. A perturbative QCD evolution in next-to-leading order is used to determine $g_1^{\rm p}(x)$ at a constant $Q^2$. At $Q^{2} = 10$ GeV$^{2}$ we find, in the measured range, $\int_{0.003}^{0.7} g_{1}^{\rm p}(x){\rm d}x = 0.139 \pm 0.006~({\rm stat})\pm 0.008~({\rm syst)} \pm 0.006~({\rm evol})$. The value of the first moment $\Gamma_{1}^{\rm p} = \int_{0}^{1} g_{1}^{\rm p}(x){\rm d}x$ of $g_{1}^{\rm p}$ depends on the approach used to describe the behaviour of $g_{1}^{\rm p}$ at low $x$. We find that the Ellis-Jaffe sum rule is violated. With our published result for $\Gamma_{1}^{\rm d}$ we confirm the Bjorken sum rule with an accuracy of $\approx 15\%$ at the one standard deviation level.

Abstract

We present a new measurement of the spin-dependent structure function $g_{1}^{\rm d}$ of the deuteron from deep inelastic scattering of 190 GeV polarized muons on polarized deuterons. The results are combined with our previous measurements of $g_{1}^{\rm d}$. A perturbative QCD evolution in next-to-leading order is used to compute $g_{1}^{\rm d}(x)$ at a constant $Q^{2}$. At $Q^{2} = 10$ GeV$^{2}$, we obtain a first moment $\Gamma_{1}^{\rm d} = \int_{0}^{1} g_{1}^{\rm d}{\rm d}x = 0.041 \pm 0.008$, a flavour-singlet axial charge of the nucleon $a_{0} = 0.30 \pm 0.08$, and an axial charge of the strange quark $a_{s} = -0.09 \pm 0.03$. Using our earlier determination of $\Gamma_{1}^{\rm p}$, we obtain $\Gamma_1^{\rm p} - \Gamma_1^{\rm n} = 0.183 \pm 0.035$ at $Q^2 = 10\,\mbox{GeV}^2$. This result is in agreement with the Bjorken sum rule which predicts $\Gamma_1^{\rm p} - \Gamma_1^{\rm n} = 0.186 \pm 0.002$ at the same $Q^2$.

Abstract

A muon beam polarimeter has been built for the SMC experiment at the CERN SPS, for muon energies of 100 to 200 GeV. The beam polarisation is determined from the energy spectrum of positrons from the decay μ+ → e+ νcνμ. A polarisation of - 0.82 is measured with a relative systematic accuracy of 3%.

Abstract

In the energy region 10 - 100 TeV both the c.r. composition from direct measurements and the cross section for high energy secondary production in the very forward region for p-air interactions are rather uncertain. Contemporaneous measurements of the total energy and of the threshold energy/nucleon of the primary particle can be provided by the atmospheric Cherenkov light and high energy muons. These measurements are performed by the combined operation of the Cherenkov array of the EAS-TOP experiment on the surface (810 gcm(2) atmospheric depth) and of the LVD experiment in the underground Gran Sasso Laboratories (3300 m w.e.; E-mu(th) = 1.3 TeV) leading to the measurement of < N-mu > (E-mu > 1.3 TeV, E-o) in the given energy range. The combined operation of the experiments and preliminary results are reported.

Abstract

A muon beam polarimeter was built for the SMC experiment at the CERN SPS, for beam energies of 100 and 190 GeV. The beam polarisation is determined from the asymmetry in the elastic scattering off the polarised electrons of a ferromagnetic target whose magnetisation is periodically reversed. At muon energies of 100 and 190 GeV the measured polarisation is P-mu = -0.80 +/- 0.03 (stat.) +/- 0.02 (syst.) and P-mu = - 0.797 +/- 0.011 (stat.) +/- 0.012 (syst.), respectively. These results agree with measurements of the beam polarisation using a shape analysis of the decay positron energy spectrum. (C) 2000 Elsevier Science B.V. All rights reserved.

Abstract

We present the results of the spin asymmetries $A_1$ of the proton and the deuteron in the kinematic region extending down to $x=6\cdot 10^{-5}$ and $Q^2=0.01$ GeV$^2$. The data were taken with a dedicated low $x$ trigger, which required hadron detection in addition to the scattered muon, so as to reduce the background at low $x$. The results complement our previous measurements and the two sets are consistent in the overlap region. No sig\-ni\-fi\-cant spin effects are found in the newly explored region.

Abstract

Arrays of limited streamer tubes of the Iarocci type were deployed in our experiment at CERN as part of a forward muon detector system with provisions for the beam to pass through the center of each panel in the array. A total of 16 4 m x 4 m panels were assembled with inductive readout strips on both sides of each panel. An active feedback system. was deployed to regulate the high voltage to the streamer tubes to insure a constant efficiency for minimum ionizing particles. The arrays were operated in this environment for over five years of data taking. Streamer tube track-reconstruction efficiencies and tube replacement rates are reported.

Abstract

The polarized target of the Spin Muon Collaboration at CERN was used for deep inelastic muon scattering experiments during 1993-1996 with a polarized muon beam to investigate the spin structure of the nucleon. Most of the experiments were carried out with longitudinal target polarization and 190 GeV muons, and some were done with transverse polarization and 100 GeV muons. Protons as well as deuterons were polarized by dynamic nuclear polarization (DNP) in three kinds of solid materials - butanol, ammonia, and deuterated butanol - with maximum degrees of polarization of 94%, 91% and 60%, respectively. Considerable attention was paid to the accuracies of the NMR polarization measurements and their analyses, the accuracies achieved were between 2.0% and 3.2%. The SMC target system with two cells of opposite polarizations, each cell 65 cm long and 5 cm in diameter, constitutes the largest polarized target system ever built and facilitates accurate spin asymmetry measurements. The design considerations, construction and performance of the target are reviewed, (C) 1999 Elsevier Science B.V. All rights reserved.

Abstract

We present evidence for a dependence of the average deep underground muon energies on shower size in the coincident EAS-TOP and LVD data at the Gran Sasso laboratories. The measured relation agrees with a mixed chemical composition of the cosmic ray primary spectrum at energies around 10(15) eV. (C) 1998 Elsevier Science B.V.

Abstract

We present a next-to-leading order QCD analysis of the presently available data on the spin structure function [Formula Presented] including the final data from the Spin Muon Collaboration. We present results for the first moments of the proton, deuteron, and neutron structure functions, and determine singlet and nonsinglet parton distributions in two factorization schemes. We also test the Bjorken sum rule and find agreement with the theoretical prediction at the level of 10%. © 1998 The American Physical Society.

Abstract

The 1996 data taking of the SMC experiment used polarized protons to measure the spin-dependent structure function g(1) of the proton. Three liters of solid granular ammonia were irradiated at the Bonn electron linac in order to create the paramagnetic radicals which are needed for polarizing the protons. Proton polarizations of +/- (90 +/- 2.5)% were routinely reached. An analysis based on a theoretical line shape for spin-1. systems with large quadrupolar broadening was developed which allowed the nitrogen polarization in the ammonia to be determined with a 10% relative error. The measured quadrupolar coupling constant of N-14 agrees well with earlier extrapolated values. The polarization of the nitrogen nuclei was measured as a function of the proton polarization in order to provide a test of the equal spin temperature (EST) hypothesis. It was found to be closely valid under the dynamic nuclear polarization conditions with which the protons are polarized. Large deviations from EST could be induced by cross relaxing the proton and nitrogen spin systems at low fields. Nitrogen polarizations up to 40% were reached by these means.

Abstract

An analytic model of the deuteron absorption function has been developed and is compared to experimental NMR signals of deuterated butanol obtained at the SMC experiment in order to determine the deuteron polarization. The absorption function model includes dipolar broadening and a frequency-dependent treatment of the intensity factors. The high-precision TE signal data available are used to adjust the model for Q-meter distortions and dispersion effects. Once the Q-meter adjustment is made, the enhanced polarizations determined by the asymmetry and TE-calibration methods compare well within the accuracy of each method. In analyzing the NMR signals, the quadrupolar coupling constants could be determined for both the CD and the OD bonds of deuterated butanol.

Abstract

We present a new measurement of the spin-dependent structure function g 1 d of the deuteron in deep inelastic scattering of 190 GeV polarised muons on polarised deuterons, in the kinematic range 0.003 x 2 Q 2 2 . This structure function is found to be negative at small x . The first moment Γ 1 d =∫ 0 1 g 1 d d x evaluated at Q 0 2 = 10 GeV 2 is 0.034 ± 0.009 (stat.) ± 0.006 (syst.). This value is below the Ellis-Jaffe sum rule prediction by three standard deviations. Using our earlier determination of Γ 1 p , we obtain Γ 1 p − Γ 1 n = 0.199 ± 0.038 which agrees with the Bjorken sum rule.

Abstract

We analyse the proton, deuteron and neutron spin dependent structure functions at fixed $Q^{2}$ = 5 GeV$^{2}$. The experimental asymmetries for the proton, neutron and deuteron are compared and found to be consistent. The first moment of the neutron structure function is evaluated using all available data. We find that the Bjorken sum rule is confirmed within an experimental uncertainty of 17%. The quark spin contribution to the nucleon spin is small, and the strange quark spin content is different from zero.

Abstract

The 10-probe NMR system for measuring the polarization in the deuterated butanol target of the Spin Muon Collaboration is presented. It is calibrated by determining the integrated spectrum in thermal equilibrium at 1 K. Thermal stabilization and control of electromagnetic interference were effective in reducing drift and electronic noise, so that high quality thermal equilibrium signals were obtained. The calibration constant was determined with a reproducibility of 2%. Systematic effects of circuit drift and of the magnetic field shift have been studied. The resulting 4.4% uncertainty of the calibration dominates the 5% overall error on the target polarization value which was typically 0.45.

Abstract

We present the final results of the spin asymmetries A(1) and the spin structure functions g(1) of the proton and the deuteron in the kinematic range 0.0008 < x < 0.7 and 0.2 < Q(2) < 100 GeV2. For the determination of A(1), in addition to the usual method which employs inclusive scattering events and includes a large radiative background at low x, we use a new method which minimizes the radiative background by selecting events with at least one hadron as well as a muon in the final state. We find that this hadron method gives smaller errors for x < 0.02, so it is combined with the usual method to provide the optimal set of results. [S0556-2821(98)07017-9].
