[Salvage procedures of the elbow. Alternatives to elbow arthroplasty].

Destructive changes of the elbow joint represent a challenge for both patient and surgeon. Resection arthroplasty is associated with postoperative instability and loss of power and is a rarely performed procedure. Interpositional arthroplasty remains a useful option for healthy active patients with severe post-traumatic elbow arthrosis and is one of the oldest methods used to reconstruct the elbow. The principle of interpositional arthroplasty is based on a sparing resection of the destroyed joint surface and on creating a congruent elbow joint with human tissue. Nowadays, autogenous dermis, fascia lata or Achilles allograft are used. A preoperatively stable elbow is required to prevent instability following interpositional arthroplasty. The use of total elbow arthroplasty is limited due to the contraindications and in such cases the only remaining options are salvage procedures of the elbow. In general, arthrodesis should be performed in patients with painful osteoarthritis of the elbow with high demands on the upper extremities. Historically, tuberculosis was the most common indication for elbow arthrodesis and various methods of elbow arthrodesis have been described. However, most attention has been given to the position in which the elbow joint should be fixed and should be decided depending on the individual characteristics of the patient. Sufficient bone stock is crucial for a successful elbow arthrodesis and in cases with massive bone loss reconstruction of the elbow using an allograft can be performed to restore bone quality. However, the high complication rate of this procedure limits the scope of its use. Nevertheless, allograft procedures can restore pain-free joint function for several years.
