Achilles allograft interposition arthroplasty effectively treats failed distal ulna resections, preventing painful convergence. This safe procedure is ideal for young, active patients unsuitable for implants.

Area of Science:

Orthopedic Surgery
Reconstructive Surgery

Background:

Distal ulna resection (Darrach procedure) complications include radioulnar impingement and instability.
High failure rates and lack of superior surgical techniques necessitate alternative treatments for failed Darrach procedures.

Purpose of the Study:

To evaluate the safety and efficacy of Achilles allograft interposition arthroplasty for failed distal ulna resections.
To present a viable alternative for young, active patients where implants may be inappropriate.

Main Methods:

Resection interposition arthroplasty using an Achilles tendon allograft.
Interposition between the distal radius and resected distal ulna to prevent convergence.

Main Results:

Achilles allograft interposition arthroplasty is a safe and highly effective treatment.

Keywords:

Achilles allograft distal ulna failed Darrach radioulnar impingement

The technique successfully prevents painful convergence of the radius on the ulna.

Conclusions:

Achilles allograft interposition arthroplasty is a recommended alternative for failed distal ulna resections.
This method is particularly suitable for young, active patients concerned about implant longevity.
