Complete dislocation of the talus is an extremely rare injury. We report on a case that was treated according to a surgical technique described by Günal et al. According to this technique, a pseudarthrosis is created between the tibia and the calcaneus by transposing and fixing the medial malleolus laterally and displacing the entire foot anteriorly. The result was considered to be initially unsatisfactory. At the 2-year follow-up examination, the outcome was considered to be satisfactory. This was attributed to preservation of motion and stability in the new mortise.

The aim of the article is to present the medium-term results of surgical treatment of Schatzker's IV, V, and VI tibial plateau fractures, in a retrospective study of 22 patients at a level-1 trauma center. Twenty-two of 34 patients with Schatzker's IV–VI fractures completed follow-up at a mean of 56 months (range: 7–103 months). Patients' mean age was 47.6 years (range: 18–76 years). Open reduction and internal fixation were performed in 16 patients, while external fixators were used in the remaining six patents. Patients were assessed radiologically for the presence of arthritis using the Kellgren–Lawrence scale. Functional outcomes were measured using the Lysholm's knee score, knee injury, and osteoarthritis outcome score (KOOS). Quality of life was also assessed postoperatively using the EuroQol-5D (EQ-5D) form and EQ-VAS (visual analogue scale) score. There were no postoperative infections and no fracture went on to nonunion. Absence of arthritic change was noted in only 6.3% of cases. The average KOOS score was 80 and the average Lysholm's score was 84.91. Regarding the postoperative quality of life, mobility was impaired in 45.5%, self-care in 27.3%, and usual activities in 36.3% of patients. Pain or discomfort was reported in 77.2% and anxiety or depression in 40.9% of cases. The mean VAS score was 77.8. Eighty percent of patients had returned to their previous activities at the time of last follow-up. Although complex tibial plateau fractures are associated with a high rate of complications and can have a severe impact on the injured knee, most patients had quite satisfactory results during their medium-term clinical evaluation, in our study. It is a Level IV case series study.

The effect of salmon calcitonin on the maturation of the regenerate bone was assessed in an experimental model in rabbits. Twenty-six New Zealand White male rabbits, approximately 5 months old and weighing 3 to 3.5 kg, were subjected to a mid-diaphyseal tibial osteotomy. After 5 days, the right tibia was lengthened gradually at a rate of 0.375 mm every 12 hours, for 10 days. Ten international units of salmon calcitonin were administered daily subcutaneously to the study group (14 animals), whereas the animals of the control group (12 animals) were injected with a placebo, for the duration of the experiment. The bone mineral density of the regenerate bone was assessed on Days 20, 35, 45, and 55 of the experiment, in both groups, using dual energy xray absorptiometry. No statistical significant difference was found in the dual energy xray absorptiometry measurements between the study and control groups regarding the change of the bone mineral density of the new bone relative to a preoperative baseline measurement. Characteristic time-related changes were observed in the bone mineral density of the regenerate bone during its maturation, which proved to be identical in both groups. It seems that the administration of calcitonin does not enhance regenerate bone mineralization rate and tendency during bone lengthening.
