Interdisciplinary consensus statements on imaging of DRUJ instability and TFCC injuries.

Objectives: The purpose of this agreement was to establish evidence-based consensus statements on imaging of distal radioulnar joint (DRUJ) instability and triangular fibrocartilage complex (TFCC) injuries by an expert group using the Delphi technique.

Methods: Nineteen hand surgeons developed a preliminary list of questions on DRUJ instability and TFCC injuries. Radiologists created statements based on the literature and the authors' clinical experience.

Benign subcutaneous emphysema: a rare and challenging entity .

We report the case of a craftsman who developed a rapidly progressive subcutaneous emphysema of his forearm after a minor stab injury into the palm of his hand. Based on our case report we discuss differential diagnosis and management of acute subcutaneous emphysema.

Transosseous Sutures in Tendon-to-Bone Repairs: the Role of the Epitendinous Suture.

Background: Numerous transosseous fixation techniques for flexor tendon injuries in Zone 1 of the hand have been described in the literature. While relatively high maximal loads to failure are documented in different biomechanical experiments, several tests revealed a low 2 mm gapping resistance of the tendon-to-bone repairs. We therefore aimed to investigate the effect on gap formation adding a peripheral suture to an established transosseous fixation technique.

Biomechanical analysis of a new 8-strand technique for flexor tendon repair.

We sought to compare the strength and rupture sites of a new 8-strand suture technique with those of an established 6-strand flexor tendon repair through biomechanical analysis. This new 8-strand suture pattern places minimal suture material in the remodeling zone and focuses on protecting the knot, a well-known weak point of the suture construct. The knot was buried within the tendon so as to not interfere with tendon gliding.
