Avascular necrosis involving more than one carpal bone is rare, and the appropriate treatment for this condition has not yet been established. In this report, two patients with concomitant Preiser's and Kienböck's disease who also had severe wrist pain without obvious traumas were treated by closing radial wedge osteotomy (CRWO). Clinical evaluation showed that CRWO was effective against both conditions and indicated that it is more suitable for early stage than stage II diseases of the Hebert and Lichtman classifications.

Traditional packed beds in chromatography suffer from increased band broadening due to the random nature of packing, leading non-ideal fluid flow and channeling. To address these challenges, pillar array columns have been developed, offering improved performance over random packing thanks to their homogenous fluid profiles. The study aims to i) evaluate fluid dynamics and chromatographic performance across different PAC morphologies, ii) establish the influence of column morphology on performance, and iii) assess the correlation between chromatographic performance and hydrodynamic parameters.

Wearable motion capture gloves enable the precise analysis of hand and finger movements for a variety of uses, including robotic surgery, rehabilitation, and most commonly, virtual augmentation. However, many motion capture gloves restrict natural hand movement with a closed-palm design, including fabric over the palm and fingers. In order to alleviate slippage, improve comfort, reduce sizing issues, and eliminate movement restrictions, this paper presents a new low-cost data glove with an innovative open-palm and finger-free design.

Wrist movements play a crucial role in upper-limb motor tasks. As prosthetic and robotic hand technologies have evolved, increasing attention has been focused on replicating the anatomy and functionality of the wrist. Closely imitating the biomechanics and movement mechanisms of human limbs is expected to enhance the overall performance of bionic robotic hands.

Objective: To investigate the short-term clinical effect of closed reduction single arm external fixator combined with percutaneous needle fixation in the treatment of C1 distal radius fracture in elderly patients.
Methods: Between December 2022 and December 2023, a total of 60 elderly patients diagnosed with type C1 distal radius fractures were treated, comprising 9 males and 51 females. The age ranged from 65 to 84 years old, with an average of (72.
Objective: To compare the short-term clinical efficacy and safety of closed reduction with Kirschner wire fixation versus open reduction with plate fixation for treating osteoporotic Colles' fractures in middle-aged and elderly patients.
Methods: Between January 2018 and January 2023, 119 patients with Colles fractures were retrospectively analyzed, including 39 males and 80 females, aged from 48 to 74 years old with an average of(60.58±6.
