Objective To compare the clinical outcomes of primary metal-on-metal total hip replacement (MoM-TR) converted to uncemented total hip replacement (UTR) or cemented total hip replacement (CTR) in patients with femoral neck fractures (AO/OTA: 31B/C). Methods Patient data of 234 UTR or CTR revisions after primary MoM-TR failure from March 2007 to January 2018 were retrospectively identified. Clinical outcomes, including the Harris hip score (HHS) and key orthopaedic complications, were collected at 3, 6, and 12 months following conversion and every 12 months thereafter. Results The mean follow-up was 84.12 (67–100) months for UTR and 84.23 (66–101) months for CTR. At the last follow-up, the HHS was better in the CTR- than UTR-treated patients. Noteworthy dissimilarities were correspondingly detected in the key orthopaedic complication rates (16.1% for CTR vs. 47.4% for UTR). Statistically significant differences in specific orthopaedic complications were also detected in the re-revision rate (10.3% for UTR vs. 2.5% for CTR), prosthesis loosening rate (16.3% for UTR vs. 5.9% for CTR), and periprosthetic fracture rate (12.0% for UTR vs. 4.2% for CTR). Conclusion In the setting of revision of failed primary MoM-TR, CTR may demonstrate advantages over UTR in improving functional outcomes and reducing key orthopaedic complications.

Linear Polarisation

The open circuit potential and linear polarisation resistance were measured during pin-on-plate tribometer tests for three different total hip replacement bearing material combinations in 0.35% NaCl and bovine serum solutions. In addition, surface analysis was performed using laser interferometry and focused ion beam scanning electron microscopy. It was found that the level of tribologically enhanced corrosion taking place at the bearing surface was substantially higher for metal-on-metal tribocouples than metal-on-polymer ones. Tribological depassivation may be reduced by the presence of organic boundary lubricants.

Nationwide Register Study

Background: Few previous studies have analysed the possible teratogenic effect of maternal total hip replacement (THR) on congenital anomalies. The aim of this study was to estimate the risk of major congenital anomalies in the offspring of women with THR. Furthermore, we compared the risks based on type of implant (metal-on-metal [MoM]/non-MoM). Methods: The study population for this register-based cohort study was gathered from six Finnish national registers. All fertile-aged females who underwent THR from 1980 to 2007 and three reference females for each THR patient without THR were selected. THR operation day was the start of the follow-up for both groups. Information on pregnancies, induced abortions (IA) and congenital anomalies was gathered for the years 1987–2007 and the proportions of congenital anomalies were compared. Results: In the THR group, 2429 women had 256 pregnancies, 205 (80.1%) deliveries and 51 (19.9%) IAs. In the reference group, 7276 women had 1670 pregnancies, 1443 (86.4%) deliveries and 236 (13.6%) IAs. There was no difference in the incidence of major anomalies between the THR (3.5%, n = 9) and the reference group (3.6%, n = 60), p = 0.91. In the THR group, there was no difference in the risk of major anomalies between the patients with a MoM-THR (10.5%, 2/19) and those with a non-MoM (2.9%, 7/241) (OR 3.93, 95% confidence interval 0.76–20.2; p = 0.13). Conclusions: Reassuringly, maternal THR does not appear to increase the risk of major congenital anomalies or pregnancies ending due to suspected foetal anomalies. Studies with larger study populations are needed to further assess the risk of anomalies in the offspring of women having MoM-THR.
