Post-traumatic intraosseous sheath development of the extensor carpi radials brevis tendon: a case report

This case highlights a rare post-traumatic deformity following a distal radius fracture, where the extensor carpi radialis brevis tendon formed an intraosseous sheath. It underscores the importance of considering unique anatomical changes when planning surgical interventions. This is the first reported case of an interosseous tendon sheath development around a tendon postdistal radius fracture, expanding the spectrum of known complications.
