Objective: The aim of this study was to determine the prevalence of predatory journals in Orthopedics and Traumatology and to investigate the relationship of these publications with the regulations of scientific fields made in recent years in Turkey. Methods: The journals and publishers between the years 2000e2018 were screened and websites visited one by one on the basis of the orthopedic journals and publishers list determined as predators or possible predators. Orthopedic publications originated from Turkey was detected in these predatory journals. Article admissions, article processing charges, editorial and referee average response times were reviewed from the websites of journals. In addition, the effect of changing associate professorship application requirements and academic incentive regulation on the preference of predatory journals was examined. Results: Between 2000 and 2018 years 1626 issues which can be reached in 282 journals were examined. 4795 articles were screened in 29 journals which have articles originated from Turkey. One hundred and six (2.21%) articles which originated from Turkey was reached in these publications. Average article processing charge was $865 ($ 0e1819). Fifty-nine of 106 (55%) articles originated from Turkey were found in only 4 journal. Journals which have articles originated from Turkey were not on the Web of Science list. The response time to the articles was between 2 and 6 weeks in these journals. After the change criteria in associate professorship in 2016, 3.32 fold increase in annual average number of publications originated from Turkey have been identified in predatory journals. After the change criteria in academic incentive regulation in 2015, 4.76 fold increase in annual average number of publications originated from Turkey have been identified in predatory journals. Conclusion: The number of articles in predatory journals is increasing all over the world. This situation also valid in the field of Orthopaedics and Traumatology in Turkey. Authors should pay attention regarding predatory journals not only article processing charges but also very short evaluation period.

Joint Diseases and Related Surgery (JDRS), the official journal of the Turkish Joint Diseases Foundation, is an international, peer-reviewed, immediate open access journal. All published articles in JDRS has been free for everyone, without embargo, since 1990.

This study reviews the long-term efficacy of short-segment posterior instrumentation and fusion (SSPIF) in treating thoracolumbar burst fractures. Authors retrospectively reviewed the radiographic results of single-level thoracolumbar burst fractures treated by SSPIF. Vertebral body height and wedge angles were measured on the preoperative, postoperative, and follow-up radiographic images. The degree of pain and work ability was measured using the Denis scale. The analysis consisted of 12 patients with a mean age of 39.7 years (range 21–60) and a mean follow-up of 225.6 ± 20.3 months. There were significant differences among the wedge angles at preoperative and other periods of time, but there was no significant difference between the early postoperative and all other time periods afterwards (P < .001, P = .567, P = .937, P = .879). SSPIF effectively restored the anterior and middle vertebral body height and wedge angle deformities, and the improvement was maintained for almost 20 years after the surgery. Therefore, SSPIF is a safe and effective modality of treatment for thoracolumbar burst fractures.

Objective: The purpose of this study was to investigate the results and complications in patients who had low-grade chondrosarcomas in the appendicular skeleton and were treated by intralesional curettage and cementation within the scope of 25 years of experience in a single center. Methods: Ninety-one patients (72 female and 19 male) were retrospectively analyzed. The median at the time of surgery was 43 (17-78) years, and the median follow-up was 102 (26-288) months. All patients were treated by intralesional curettage followed by cementation with high-viscosity bone cement (polymethylmethacrylate). Complications and local recurrence rates, as well as clinical outcome scores were recorded. Results: Five patients (5.49%) developed local recurrence at an average of 6.6 (6-9) months postoperatively. Four were treated with localwide excision and reconstruction with tumor prosthesis. One patient received recurettage and cementation. Two recurred patients were dedifferentiated into grade II chondrosarcomas in the last intervention. No major postoperative complication was identified in the series. Patients achieved an average Musculoskeletal Tumor Society scoring system of 92.4% (standard deviation 5.2; range 80-100) in the sixth postoperative month. Musculoskeletal Tumor Society scores in the recurrent patients decreased from an average of 90% to 75.3% after the final intervention. Conclusion: Intralesional curettage and cementation seem safe and reliable techniques with low recurrence and complication rates in treating low-grade chondrosarcomas of the appendicular skeleton. Clinical, radiological, and pathological evaluations are mandatory before surgical intervention, and a multidisciplinary approach is crucial. A strict follow-up regimen in the early postoperative period is needed and strongly recommended to detect local recurrence.

OBJECTIVE: This study aims to investigate the effect of bone grafting on the bone union in exchange nailing (EN) for the treatment of femoral shaft nonunions. METHODS: A total of 26 patients (16 male) were included in this study. The mean age of the patients was 36.1 +/- 9.3. Bone grafts were used in 8 patients (bone graft group), and EN was performed without bone grafting (no bone graft group) in 18 patients. Etiology, fracture type, location, and classification of the fractures at the time of initial injury were evaluated. The reduction type (open or closed) and locking status of the nails were also noted. Nonunion types were recorded. In the bone grafting group, iliac bone autografts were used in seven patients and a synthetic bone graft was used in one patient. Following EN, the presence and duration of bone union, and the increase in the nails' diameter were analyzed for each group and compared. RESULTS: Union rates were 100% and 94.4% in bone grafting and no bone grafting groups, respectively. The mean union period was not significant between the groups (22.5 and 16.5 months, respectively). The mean increase in the nail diameter was 1.88 mm in the bone graft group and 2.00 mm in the no bone graft group (p>0.05). CONCLUSION: This study demonstrated that high union rates can be achieved with EN by means of using larger diameter nails with or without bone grafting in the management of femoral shaft nonunions, and bone grafting had no significant effect on union rates and periods.

The current study aimed to objectively evaluate the fit of a rectangular, tapered stem to the severely dysplastic hips on the basis of the proximal femoral anatomy and the dimensional properties of the stem. It was hypothesized that the stem size planned with accordance to the diaphyseal canal width alone can accommodate the distal femur successfully with no sizing mismatch. Forty-six patients (53 hips) suffering from secondary osteoarthritis due to hip dysplasia scheduled for total hip arthroplasty (THA) with a subtrochanteric transverse shortening osteotomy were included. All hips were Crowe type 4. All patients underwent preoperative computed tomography imaging. Height of femoral head center (HCH) was determined. Medullary canal diameter measurements at different levels were made. These were made at a level (1) 35% of HCH above the lesser trochanter (DT +35), (2) 70% of HCH below the lesser trochanter (DT -70), and (3) at the level of isthmus (Di). Medullary canal flare indices were calculated from the individual parameter ratios. Similar measurements were carried out for the different sizes of the femoral stem. The mean DT +35 was 41.9 ± 6.4 mm, the mean DT-70 was 17.3 ± 2.2 mm, and the mean Di was 12.8 ± 1.9 mm. In all femurs, the width of the isthmus was wider than that of the corresponding femoral stem isthmus. The femoral stem sizes established with respect to the diaphyseal width of the femur were all compatible with the isthmus width of the femur. Tapered and rectangular stems can accommodate the proximal femur above and below the osteotomy level in Crowe type IV hip dyplasia patients, thereby constituting a viable option as the femoral stem in this patient group with technically demanding difficulties.
