Intraosseous DRUJ prosthesis insertion technique

(A) A curvilinear incision was made on the ulnar side of the distal forearm extending over DRUJ on dorsal side.

(B) A length of approximately 24 mm was cut from the distal ulna surface, and 20 mm was cut from the distal ulna.

(C) The osteophytes were removed and the remaining joint cartilage was destroyed.

(D) Arthrodesis of the DRUJ is performed using a fully-threaded cancellous screw in the distal and a partially-threaded cancellous screw in the proximal side.

(E) Distal stem is inserted.

(F) The proximal stem and the locking part are inserted.

(G) The globe is placed between the two pieces of the locking system.

(H) These two pieces were rotated 180-degree relative to each other for the final locking of the prosthesis, and the locking part was fixed to the proximal stem using the screws designed in the prosthesis.
