Introduction: Although there is no consensus in the literature, it is believed that the Soong classification system and fracture pattern are risk factors for plate removal in distal radius fractures. Hypothesis: The aim of this large-scale study was to evaluate the relationship between Soong classification, fracture pattern, and implant removal in distal radius fractures. Materials and methods: We retrospectively evaluated 795 patients who underwent surgery using a volar locking plate for distal radius fractures at our clinic between 2005 and 2022. The patients were divided into two groups: implant removed, and implant retained. The groups were examined for demographic data, follow-up periods, fracture classifications, and radiological parameters. Additionally, the patients were divided into groups and compared according to the Soong classification, which was determined according to implant placement. Indications for implant removal were also included in this study, and their relationships with other parameters were evaluated. Results: A total of 123 and 672 patients were included in the implant removed and retained groups, respectively. The average age of the implant removed group was significantly lower (p = 0.005). There were no significant differences between the two groups in terms of fracture classification or other radiological parameters. In the implant removed group, the rate of grade 2, according to the Soong classification, was statistically higher than that in the other groups (p = 0.019). Flexor tenosynovitis was the most common reason for implant removal. Conclusion: The Soong classification system is an important risk factor associated with implant removal. This risk may increase, particularly among young patients. Surgeons should consider placing the distal radius locking plate as proximally as possible to reduce the frequency of implant removal.

Systemic Iodine Levels Increase With Povidone-Iodine Irrigation, but Does This Affect Thyroid Functions? a Case-Control Study
(Bmc, 2024) Ertan, Mehmet Batu; Basarir, Kerem; Kocaoglu, Hakan; Aydugan, Mehmet Yagiz; Guengoer, Erdal
BackgroundIntraoperative irrigation with diluted povidone iodine (PI) can be used to reduce the incidence of infection-related complications in arthroplasty surgeries. Since PI is associated with many interventions, especially skin antisepsis, its systemic effects are being studied. The aim of our study is to evaluate the systemic effects of PI, which we use as an irrigation solution, by means of urine iodine and thyroid function tests.MethodsIn this case-control study, 96 patients who underwent knee or hip arthroplasty were included and divided into two groups according to the irrigation solution. In the first group, PI was added to the standard irrigation. The second group was considered as the control group and only standard irrigation was applied. Urine iodine, thyroid stimulating hormone, free T3 and free T4 values were compared in the preoperative and postoperative periods of these two groups. In this way, the effect of absorbed iodine on thyroid functions was investigated.ResultsIn the diluted PI group, urinary iodine levels were measured at maximum levels (450 mu g/L) in the early postoperative period in most of the patients. The statistically significant difference in urinary iodine levels between the PI group and the control group, which started in the early postoperative period, continued until the last follow-up on the 14th postoperative day. In terms of thyroid functions, the observed differences were not statistically significant.ConclusionStudies to reduce periprosthetic infection show that PI can be preferred for irrigation before the closure of the joint area in total joint arthroplasty. Although the success of this treatment in periprosthetic infection has been investigated, its systemic examination has not been demonstrated. It was determined that PI treatment, which was seen to decrease in the systemic circulation within 14 days, did not show a statistically significant change in terms of thyroid functions when used at the determined concentration and duration. These results should be evaluated with larger and longer-term studies.Trial registrationClinical trials ID no. NCT05599841.
