Abstract: The present disclosure generally relates to an elbow arthoplasty prosthesis that includes an ulnar component, a humeral component, one or more articulation liners, and a retention trap. The ulnar component includes a spherical bearing head that can be inserted into the humeral component in a number of orientations. The articulation liners and the retention trap are operatively engaged to the humeral component to retain the ulnar component within a humeral socket. The present disclosure also relates to methods of assembling and implanting the prosthetic device.

Abstract: A secondary borane featuring two ortho-carborane substituents [HBoCb2, oCb=ortho-carborane] is useful as a powerful hydroboration reagent. The Lewis superacid, bis(1-methyl-ortho-carboranyl)borane, is rapidly accessed in two steps. It is a very effective hydroboration reagent capable of the hydroboration of alkenes, alkynes, cyclopropanes, and allenes. The large steric profile prevents double hydroboration of alkynes and promotes regioselectivity in allenes. The compound is a Lewis superacidic secondary borane and effective neutral hydroboration reagent.

Abstract: A new and innovative medical sizing instrument and method are provided for determining an appropriate depth and/or length of a clavicle hook plate for a patient. The provided medical sizing instrument may enable a surgeon to determine an appropriate hook depth without having to switch between different components, such as a series of templates. In an example, a surgeon may insert the medical sizing instrument into a patient the same as the surgeon would a clavicle hook plate, adjust the hook depth on the medical sizing instrument until a hook depth is obtained that appropriately maintains the anatomical alignment of the patient's clavicle and acromion, and read an indicated depth on the medical sizing instrument. The surgeon may then remove the medical sizing instrument from the patient and select the appropriate clavicle hook plate to insert into the patient.

Abstract: The described process synthesizes a halide-free single-site borane compound product tris(ortho-carboranyl)borane, or BoCb3. BoCb3 has Lewis superacid properties. The compounds, BoCb3, are thermally stable, and not reactive towards oxygen, but are sensitive to water. The characteristic high fluoride ion affinity is further translated to the catalytic C—F bond activation reactions of the unactivated alkyl fluorides towards the reduction and C—C bond forming reactions with silanes, and Fridel-Crafts type reactions with arenes. The potential of the synthesized Lewis acid as a catalysis is anticipated.
