Rethinking polyiodides: the role of electron-deficient multicenter bonds.

Despite a bicentennial history, the interest in polyiodides and related systems still flourishes. The chemical puzzle provided by the intricate nature of chemical bonding in these polyanions remains challenging these days. The advent of the halogen bond and the spreading interest in supramolecular interactions of halogen-based systems promoted further recent interest.

Intramedullary Nail Fixation for Metacarpal Fracture: A Case Report and Review of the Clinical and Biomechanical Evidence.

We present two cases of complex metacarpal fractures treated with an intramedullary locking nail. This is an emerging fixation method that minimizes tissue insult, provides sufficient stability, and allows early mobilization. Locking nails accommodate the capture of fractured fragments in complex unstable patterns and provide longitudinal and rotational stability.

Functional composite spacer (antibiotic cement around a hemiarthroplasty) for the treatment of shoulder infections: minimum 5-year outcomes.

Background: Periprosthetic infections remain a challenging complication after shoulder arthroplasty, and an ideal treatment protocol has yet to be established. Two-stage revision is a common approach. Historically, the first stage entails placement of an all-cement antibiotic spacer.
