Injuries to the flexor tendon pulley system of the hand
The tendon-bone distance shows promise as an indirect approach in determining singular A2 and A4 pulley ruptures, but has its limitations where the A3 pulley is concerned. The flexor tendon pulley system of the finger functions to maintain the flexor tendons of the fingers close to the phalanges, enabling full range of motion in finger flexing movements. These structures are subjected to extreme forces in sports such as rock climbing, and their rupture is a frequent consequence. Accurate diagnosis of pulley injuries depends on the use of crucial imaging techniques, but these are often accompanied by challenges. The article of Schöffl et al. (2016) offers, next to some good visuals, a measurement system for the ultrasound diagnostics of various pulley rupture combinations.
