pleuropneumoniae serovar 1, 3, 5, or 7. Serum samples collected at the day of inoculation or vaccination and 7, 14, 21, and 28 days later were used to compare the assays. On samples from experimentally infected pigs, the dual-plate CF assay, quad-plate ELISA-1,

single-plate ELISA-2, and single-plate MK-0518 in vivo ELISA-3 had sensitivities of 0.46, 0.74, 0.13, and 0.13 and specificities of 0.90, 1.0, 1.0, and 1.0, respectively. Vaccinated pigs were identified only by the dual-plate CF assay and the quad-plate ELISA-1. In addition, 90 serum samples with unknown A. pleuropneumoniae exposure collected under field conditions were tested with all assays. The agreement of the 4 assays on field samples was slight to fair. While several assays are available for demonstration of A. pleuropneumoniae exposure, differences in assay targets complicate test choices. Decisions on which assay or combination of assays to use depend on the specific reasons for running the assays.”
“Background: Acromioclavicular joint dislocations are common orthopaedic injuries. Numerous operative techniques have been

described, but the gold standard has yet to be defined. The goal of fixation is to create a stiff and strong reconstruction of the coracoclavicular ligaments to provide optimal stability. The modified Weaver-Dunn Bindarit concentration is the traditional surgical procedure. However, due to the high rate of recurrent instability with this technique, a shift toward a more anatomic repair has occurred.\n\nPurpose: To evaluate the biomechanical performance of multiple types of coracoclavicular ligament reconstruction.\n\nStudy Design: Controlled laboratory study.\n\nMethods: SC79 Thirty fresh-frozen human cadaveric shoulders were assigned to 1 of 5 reconstruction groups or a control group: modified Weaver-Dunn, nonanatomic allograft, anatomic allograft, anatomic suture, and GraftRope. A type III acromioclavicular joint dislocation was simulated in all specimens. The

5 techniques were completed, and a cyclic preload and a load-to-failure protocol were performed.\n\nResults: The control had an average load to failure of 1330.6 +/- 447.0 N. Compared with all techniques, the anatomic allograft had the highest load to failure, 948 +/- 148 N. It had a significantly higher load to failure than the modified Weaver-Dunn (523.2 +/- 98.6 N, P = .001), the anatomic suture (578.2 +/- 195.3 N, P = .01), the nonanatomic allograft (591.2 +/- 65.6 N, P = .003), and the GraftRope (646 +/- 167.4, P = .016). No significant difference in load to failure was found between the remaining techniques.\n\nConclusion: The anatomic allograft reconstruction has superior initial biomechanical properties compared with the modified Weaver-Dunn, nonanatomic allograft, anatomic suture, and GraftRope techniques.\n\nClinical Relevance: Anatomic reconstruction of the coracoclavicular ligaments with allograft may provide a stronger biological solution for acromioclavicular joint dislocations.
