A systematic review and network meta-analysis of outcomes after total wrist arthroplasty in inflammatory and non-inflammatory arthritis.

This systematic review analysed the available evidence on the clinical outcomes of total wrist arthroplasty (TWA) in patients with inflammatory and non-inflammatory arthritis. After screening, 12 studies met the inclusion criteria. They involved 359 patients with 378 TWA implants. The results showed that TWA significantly improved Disabilities of the Arm, Shoulder and Hand (DASH)/Quick-DASH scores and pain visual analogue scale scores in both arthritis groups compared with preoperative values. However, there was no statistically significant difference in the outcome scores between the two groups. Three studies reported Patient-Rated Wrist Evaluation (PRWE) scores, and TWA significantly improved PRWE scores in non-inflammatory arthritis but not in inflammatory arthritis, with no significant difference in postoperative outcome scores between the two groups. Although the included studies have limitations, the review suggests that TWA may be a successful treatment for wrist pain in individuals with either inflammatory or non-inflammatory arthritis. However, further high-quality trials are needed to confirm these findings.

Dual mobility hip arthroplasty: iatrogenic intraprosthetic dislocation of a 22 mm head.

We describe the first intraprosthetic dislocations of a 22 mm head in a dual mobility hip replacement in the literature. This case emphasises the importance of information gathering and planning when dealing with arthroplasty complications. Furthermore, it highlights the necessity of adequate muscle relaxation and analgesia when dealing with hip dislocations. A 78-year-old patient presented to the emergency department (ED) with a spontaneous dislocation of her left dual-mobility total hip replacement 3 months after first-stage revision surgery for infection. Reduction via manipulation under analgesia was then attempted in the ED but was ultimately unsuccessful; an iatrogenic intraprosthetic dislocation of the polyethylene liner was sustained. Several factors may have contributed to liner dislocation: a failure to appreciate the implant type, multiple manipulations in ED were attempted under analgesia, but no sedation or muscle relaxation was administered to the patient. The patient subsequently underwent revision surgery.
