Pseudarthrosis of the scaphoid

The scaphoid is one of the 8 small bones of the wrist that plays a stabilizing role. After a fracture, it can happen that the scaphoid does not consolidate, we speak then of pseudarthrosis. Fragments create friction during wrist movements. These frictions damage the cartilage and can cause osteoarthritis.

Depending on the stage of development, your surgeon may suggest one of the surgical procedures described below. It is also possible that he associates several of these gestures during the procedure.

Osteosynthesis

Consists in fixing the two parts of the fractured bone using screws. This procedure is performed as outpatient care and allows recovering a practically normal articular mobility.

Graft

Consists in taking a small graft at the level of the iliac crest (hip) and put in place this healthy graft in place of damaged part of the scaphoid. Pins or screws will hold the grafted bones. This intervention makes it possible to find an almost normal mobility of the joint.

Resection

Consists in taking the degraded scaphoid fragment if consolidation is not possible.

Prothsesis

This relatively rare procedure involves replacing the highly damaged parts of the joint with a prosthetic implant.
