process. The ulnopalmar access ensures reliable soft tissue coverage after the surgical procedure.

only the extensor carpi ulnaris muscle or anconaeus muscle is pushed off in the proximal third in front of
the dorsal ulnar surface.
Access to the radius according to Thompson, Henry or Boyd
Depending on the preoperative planning and the later position of the IPS® Implants Forearm
Reconstruction implant based on the case report, one of the three accesses according to Thompson, Henry

Positioning and use of the drill and marking guide on the ulna
The drill and marking guide is aligned with the ulna as defined in the pre-operative planning and illustrated
in the case report, and provisionally fixated using Kirschner wires. An image converter check is performed
to confirm the correct position of the drill and marking guide, and to correct it if necessary. In the next step,
the holes are pre-drilled with the drill and marking guide and using the respectively appropriate drill
bushing:
