[Osseous rupture of the attachment of the tendon of the extensor carpi radialis brevis muscle].

The author reports on a 42-year-old male patient who presented in our clinic with swelling over the left wrist bones after a fall. Dorsal and palmar wrist movement was painful, yet nearly equal on both sides. The X-ray showed an isolated osseous tendon rupture of the extensor carpi radialis brevis muscle at the base of the third metacarpal. This finding was confirmed upon surgical exploration, and a traction band was applied. After osseous healing of the fragments, the metal was removed early due to irritative synovialitis. Thereafter, the patient's wrist mobility soon became free and undisturbed.
