A Trial of the Effect of 2-Step Orthosis Treatment for Mallet Finger Fractures.

Context: Many patients report poor therapeutic outcomes following mallet finger fracture surgery. A more reliable technique is urgently needed.

Objective: To present a novel treatment for mallet finger fractures using a 2-step orthosis method.

Industrial separation of oxygen isotopes by oxygen distillation.

O-labeled water (Water- O) is a widely used starting material of F-labeled diagnostic agents in positron emission tomography (PET). Conventionally, Water- O has been separated from other stable oxygen isotope species ( O, O) by water distillation or nitric oxide distillation. However, conventional methods are costly and may have safety issues.

A randomized controlled trial of the effect of 2-step orthosis treatment for a mallet finger of tendinous origin.

Study Design: A randomized clinical trial, with patients treated either by new 2-step orthosis or by the figure-eight-type orthosis with the distal interphalangeal (DIP) joint extended.

Purpose Of The Study: To report on our new orthosis and to evaluate the treatment efficacy of using a 2-step orthosis for the treatment of a mallet finger of tendinous origin compared with a conventional orthosis.

Methods: Forty-four patients were randomized into the 2-step or conventional orthosis groups.

An ultrasonic air pump using an acoustic traveling wave along a small air gap.

An ultrasonic air pump that uses a traveling wave along a small air gap between a bending vibrator and a reflector is discussed. The authors investigate ultrasonic air pumps that make use of bending vibrators and reflectors and confirm that air can be induced to flow by generating an asymmetric acoustic standing wave along an air gap. In this paper, we proposed a novel ultrasonic air pump in which a traveling wave along an air gap induces acoustic streaming and achieves one-way airflow.

An anatomical study of the ligaments of the ulnar compartment of the wrist.

The ligamentous structures of the triangular fibrocartilage complex (TFCC) and their attachments were examined anatomically and histologically using fresh and embalmed cadavers. The TFCC was observed to have a three-dimensional structure consisting of three palmar ligaments--the short radiolunate (SRL), ulnolunate (UL), and ulnotriquetral (UT) ligaments. In addition, the attachment site of the ulnocarpal ligament (UC), which had been previously unknown, was identified.
