Reverse homodigital dorsal wraparound flap for reconstruction of distal thumb.

Reconstruction of degloving injury or amputation of distal thumb with no indication of replantation has always been a challenging problem for hand surgeons. In this study, a reverse homodigital dorsal wraparound flap innervated by the dorsal digital nerve was devised to repair degloving injury or amputation of distal thumb in 20 consecutive cases. In nine cases of thumb amputation, we skeletonized the phalanxes of the amputated part as a free cortical bone with Kirschner wires.

Biomechanical analysis of locking plates for fixation of metacarpal shaft fractures: A finite element analysis.

Background: There appears to be a paucity of knowledge about the biomechanics of locking plates for the fixation of metacarpal shaft fractures. A thorough understanding of the biomechanics of locking plates is needed to apply them correctly, optimize outcomes, and avoid complications. The purpose of this study is to investigate the biomechanics of the fixation of metacarpal fractures using locking plate-screw constructs with different numbers of screws.

Methods: A total of 19 patients with distal fingertip degloving injuries treated with digital dorsal fascial island flap combined with crossfinger flap in our hospital from April 2018 to August 2020 were retrospectively included. Semmes-Weinstein (SW) monofilament and static two-point discrimination (S-2PD) tests, active range-of-motion (ROM) of the fingers, cold intolerance, visual analog scale (VAS) score patient complications, and patient satisfaction were evaluated.

Second dorsal metacarpal artery-based index finger dorsal island flap for the management of thumb defects.

Index finger dorsal island flaps were frequently utilized by hand surgeons to reconstruct thumb defects. However, the blood supply of the traditional index finger dorsal island flap comes from the first dorsal metacarpal artery, which has a smaller diameter, more anatomical variation, and can be injured in conjunction with thumb injuries. Therefore, we design an alternative index finger dorsal island flap based on the second dorsal metacarpal artery to treat thumb skin defects.

lncRNA TUG1 promotes proliferation and differentiation of osteoblasts by regulating the miR-545-3p/CNR2 axis.

This study was designed to investigate the function of TUG1 in the proliferation and differentiation of osteoblast precursor cells hFOB1.
