Complications Following Partial and Total Wrist Arthroplasty: A Single-Center Retrospective Review

To describe our institution's experience with complications following partial and total wrist arthroplasty (TWA).

We performed a retrospective review of 105 wrist surgeries in 100 patients who underwent surgery with prosthetic replacement of the distal radius, the proximal carpus, or both at a single institution. Patient factors including age, sex, body mass index, handedness, underlying disease, and previous injury were recorded. Outcomes focused particularly on postoperative complications and need for revision surgery.

Forty-seven TWAs, 52 distal radius hemiarthroplasties, and 6 proximal carpal hemiarthroplasties were reviewed with a mean follow-up duration of 35 ± 28 months. Overall complication and revision rates were 51% (53 of 105) and 39% (41 of 105), respectively. Postoperative contracture accounted for the largest number of complications needing additional surgery (20%), followed by component failure (15%). Deep infections occurred in 2 TWAs and 1 distal radius hemiarthroplasty and required removal of hardware, antibiotic spacer placement, and a prolonged course of intravenous antibiotics prior to a definitive operation. Of those patients requiring additional surgery, 41% (n = 10) underwent at least 2 procedures, and 10% (n = 4) underwent at least 6 additional surgeries.

Although TWA and partial wrist arthroplasty are attractive treatment options for the painful arthritic wrist, there remains a noteworthy potential for complications requiring additional surgery. A detailed understanding of these risks is essential for surgeons so that patients may be counseled accordingly and that alternative treatment options may be considered.
