AI-powered finger pulley injury review for A2 and A4 pulley tears, bowstringing, climber finger injuries, flexor tendon separation, and tenosynovitis on MRI or ultrasound.
The finger pulley system keeps the flexor tendons close to the phalanges. A2 pulley injuries are well known in climbers because crimp positions create high force across the proximal phalanx. Ultrasound can dynamically show tendon bowstringing, while MRI can show pulley discontinuity, tendon separation from bone, edema, and associated tenosynovitis.
Both can help. Dynamic ultrasound can show bowstringing during active motion and is often excellent when performed by an experienced operator. MRI provides a broader view of soft tissue edema, tendon sheath fluid, and associated bone or ligament injury.
The A2 pulley is a major restraint over the proximal phalanx and takes high load in crimp grip. A complete A2 tear can allow bowstringing, reducing finger flexion efficiency and changing return-to-climbing planning.
