Ultrasound-guided trigger finger release with a minimally invasive knife: A retrospective analysis of 297 releases.

Trigger finger, or stenosing tenovaginitis, is a common condition characterized by impaired flexor tendon sliding due to thickening of the A1 pulley. While open surgical release remains the gold standard for the treatment of persistent trigger finger, there is increasing interest in minimally invasive ultrasound-guided techniques to improve precision and outcomes. The purpose of this study is to evaluate the outcomes, safety, and complications associated with ultrasound-guided trigger finger release using a minimally invasive surgical knife.

Defining trapezial dysplasia - analysis of trapezial inclination in a normal population.

We assess the distribution of trapezial inclination in a young population in order to propose a threshold for trapezial dysplasia. One hundred peritrapezial views were reconstructed from wrist computed tomography scan datasets to measure trapezial inclination. Seventy peritrapezial views were constructed from 10 datasets to assess the influence of radiograph rotation.

Clinical and ultrasonographical follow-up after standard removal of distal radius volar plates positioned distal to the watershed line.

Marginal fracture types of the distal radius may require volar plate positioning distal to the watershed line. Subsequently, plate prominence with direct friction with the flexor tendons occurs which is associated with flexor tendon pathology. Standard plate removal can be proposed.
