- April 28, 2026The ECU tendon runs in its own fibro-osseous groove on the dorsal distal ulna within the sixth extensor compartment, stabilised…
- April 28, 2026The FDP tendons pass through the carpal tunnel deep to the FDS tendons, then split through the Camper chiasm in…
- April 28, 2026The FDS tendons lie superficial to the FDP tendons in the carpal tunnel and in the finger flexor sheaths. At…
- April 28, 2026The EPB tendon shares the first extensor compartment with the APL and is involved in de Quervain tenosynovitis alongside APL.…
- April 28, 2026The APL tendon passes through the first extensor compartment with the EPB, inserting on the first metacarpal base. It may…
- April 28, 2026The extensor indicis proprius tendon runs ulnar to the EDC index finger tendon in the fourth compartment, providing independent index…
- April 28, 2026The EDM tendon in the fifth extensor compartment provides independent little finger extension (like the EI for the index). It…
- April 28, 2026The lumbrical tendons arise uniquely from the flexor tendons themselves (FDP) rather than from bone, and insert into the extensor…
- April 28, 2026The dorsal radiocarpal ligament connects the dorsal radial rim to the triquetrum and lunate, providing dorsal radiocarpal stability. It is…
