Case: Dorsal dislocations of the distal interphalangeal joint with associated volar base fractures of the distal phalanx are complex injuries that pose challenges for achieving stable reduction and restoring optimal joint function. This case report describes the successful management of a 40-year-old male cardiologist who sustained such an injury after a cricket ball trauma. The treatment involved a combined approach of closed reduction, dorsal extension block pinning, and intrafocal pinning of the volar base fracture.

Early repair of flexor tendon injuries is ideal, but delays are common. We studied the outcomes of flexor tendon repairs delayed from 5 days to 6 months and carried out under wide-awake local anaesthesia with no tourniquet (WALANT). Twenty-four patients (29 fingers) who underwent primary flexor tendon repair on zone II using a four- to six-strand core suture technique, followed by controlled early active motion therapy.

Synergistic binding ability of electrostatic tweezers and femtosecond laser-structured slippery surfaces enabling unusual droplet manipulation applications.

Lab Chip

January 2025

CAS Key Laboratory of Mechanical Behavior and Design of Materials, Department of Precision Machinery and Precision Instrumentation, University of Science and Technology of China, Hefei, 230027, P. R. China.

We propose a novel contactless droplet manipulation strategy that combines electrostatic tweezers (ESTs) with lubricated slippery surfaces. Electrostatic induction causes the droplet to experience an electrostatic force, allowing it to move with the horizontal shift of the EST. Because both the EST and the slippery operating platform prepared by a femtosecond laser exhibit a strong binding effect on droplets, the EST droplet manipulation features significant flexibility, high precision, and can work under various operating conditions.
