Salvage of failed resection arthroplasties of the distal radioulnar joint using a new ulnar head prosthesis

Management of Complications of Wrist Arthroplasty and Wrist Fusion

“…If that is not possible to perform, such as in a multiply operated wrist lacking adequate soft tissue, conversion to a total DRUJ arthroplasty can be considered. One study reports a single case of stem loosening, which was subsequently corrected with revision to a larger diameter stem (88). This same study reported another case of heterotopic ossification first noted radiographically nearly four years post-operatively that was treated conservatively.…”

“…In addition to the soft-tissue stabilization procedures just mentioned, both ulnar head and DRUJ replacement implants can be used as salvage for failed resection arthroplasty of the distal ulna (40,(87)(88)(89). Long-term outcomes following ulnar head replacement for treatment of failed distal ulnar resection have shown promise even greater than ten years after the initial surgery (88).…”

“…For ulnar head prostheses, the most common reported complication is recurrent instability (87,88). This is often the result of inadequate soft-tissue coverage and can be treated with reinforcement of the soft-tissue repair, such as with a retinacular flap (88).…”
