Objective: To investigate effect of veno-arteriolization of finger lateral vein for repairing severed finger tips.
Methods: From March 2007 to April 2012, 20 patients with severed finger tips were treated with veno-arteriolization of finger lateral vein after failure in anastomosing artery of finger over times. During operation, the dominant digital artery at proximal end and the dominant finger lateral vein at distal end was anastomosed as the blood supply, the non-superiorty finger lateral vein was anastomosed as the blood drainage.
Results: All flaps survived completely and achieved primary healing. 18 patients were successfully followed up for 6 to 12 months with satisfactory appearance and nail growth. Finger pulp was plump with good flexibility. The average length of nail was (15.6 +/- 2.7) mm and the average motion of DIP joint was (62 +/- 4) degrees. The average two point discrimination was (4.6 +/- 0.3) mm and the average sensation measurement was S3+.
Conclusion: The veno-arteriolization of finger lateral vein is a valuable method for repairing severed finger tips, which can promote nail growth, and restore fingers motion and sensation.

Lateral band snapping syndrome can be a debilitating condition involving the proximal interphalangeal (PIP) joint of the fingers. Although rare, it is thought to occur due to disruption of the finger extensor mechanism allowing inappropriate subluxation of the lateral bands over the PIP joint, leading to mechanical and painful symptoms.Here, we describe a woman in her early 40s with a painful, snapping PIP joint secondary to a work-related injury.

Rapid, point-of-care tests are critical for early diagnosis of disease and detection of biological threats. Lateral flow immunoassays (LFIAs) are well-suited for point-of-care testing due to their ease of use and straightforward readout. However, limitations in sensitivity, quantification, and integration into sample-to-result systems indicate the need for further advancements.

Background: Stroke is the leading cause of acquired motor deficiencies in adults. Restoring prehension abilities is challenging for individuals who have not recovered active hand opening capacities after their rehabilitation. Self-triggered functional electrical stimulation applied to finger extensor muscles to restore grasping abilities in daily life is called grasp neuroprosthesis (GNP) and remains poorly accessible to the post-stroke population.

Introduction: Destruction of the metacarpophalangeal joint can result in disabling pain and stiffness. Several therapeutic options are available, including pyrocarbon interposition implants. The primary endpoint of this study was assessment of clinical and radiographic outcomes in 34 patients treated with HAPY® pyrocarbon interposition implants (Tornier, Grenoble, France) with a minimum follow-up of 3 years.
