Objective This study was performed to compare the clinical and radiological outcomes of displaced femoral neck fractures (FNFs) treated with either hemiarthroplasty or total hip arthroplasty (THA) in elderly patients. Morbidity and mortality were also evaluated. Methods Twenty-two patients who underwent hemiarthroplasty and 16 patients who underwent THA for treatment of Garden type 3-4 FNFs from 2012 to 2015 were enrolled in this study. All patients were >65 years of age. Cox regression analysis was performed for mortality evaluation. Results The postoperative blood loss volume, decrease in the hemoglobin level, and transfusion rate were significantly higher in the THA group. The univariate mortality risk was higher in patients with a Charlson comorbidity score of >4, American Society of Anesthesiologists score of >2, Singh index of <3, and postoperative hospitalization of >1 week. Conclusion This study revealed no significant difference in the short-term clinical and radiological results between cementless hemiarthroplasty and THA in elderly patients with displaced FNFs. However, morbidity and mortality were associated with the presence of additional systemic diseases. THA is the preferred surgical technique in patients with displaced FNFs and low comorbidities.

Objective: Fibrous dysplasia is a slowly progressing bone lesion resulting from displacement of the normal medullary bone with abnormal fibroosseous tissue. The aim of this study was to assess the similarities and differences of our cases in relation to published reports., Material and Method: In this study, the archives of the Uludag University Medical Faculty Department of Pathology were screened for fibrous dysplasia cases between 2004 and 2016., Results: Within the mentioned period, there were 36 cases diagnosed as fibrous dysplasia. There were 21 male, and 15 female cases with an average age of 27.8±14.8 years (range 7-79 years). The most frequently affected sites were femur, costae, and craniofacial bones. There was one case localized to metacarpal bone, a very rare affection site. There were 4 polyostotic cases including 2 cases of McCune-Albright syndrome. Pelvic bone was affected in the polyostotic type, similar to published reports. Unlike former reports, however, long tubular bones were affected in male patients in our series. In our series, 32 cases had classical fibrous dysplasia, 3 cases had fibrocartilaginous, and one case had fibroosseous variants. Four cases localized to costae were accompanied by aneurysmal bone cyst. The presenting symptom was pathological fractures in a total of 4 cases, 3 localized to the femur, and 1 to the costa. Recurrence occurred in 5 cases treated with curettage. Two of the monostotic fibrous dysplasia cases developed malignant transformation into osteosarcoma., Conclusion: We conclude that our series of fibrous dysplasia cases have slight differences and mainly similar characteristics with the series reported earlier, when all features are taken into consideration.

Synovial sarcoma (SS) is a type of soft-tissue sarcoma, often linked to poor survival. Although overexpression of enhancer of zeste homologue 2 (EZH2) has been associated with poor prognosis in different tumors, a few studies investigated this link in SS. Here, we analyzed the relationship between EZH2 expression and prognostic factors in SS. We included 29 patients with SS. Immunostaining of EZH2 was performed with (D2C9) XPTM Rabbit mAb antibody, and the results were classified as low EZH2 expression (negative or weak expression) and high EZH2 expression category (moderate or strong expression). Analysis of survival in relation to prognostic factors was performed with Kaplan-Meier survival curves and Cox proportional hazard regression analysis. Our sample included 19/29 female and 10/29 male patients, with age range 16-63 years. The tumor diameter ranged from 2 to 15 cm. Necrosis was observed in 15/29 cases. Sixteen cases had >10 mitoses per 50 high-power fields (HPFs). Out of 29 cases, 14 showed low and 15 had high EZH2 expression. Statistically significant results were obtained for the association between the presence of metastasis and necrosis (p = 0.042), high EZH2 expression and distant metastasis (p = 0.018), high EZH2 expression and necrosis (p = 0.016), and high EZH2 expression and the tumor size >5 cm versus tumor size ≤5 cm (p = 0.014). Patients with all of the following: the tumor size ≤5 cm, low EZH2 expression, and without necrosis and distant metastasis had significantly longer survival time. Our results are consistent with previous studies, suggesting that EZH2 overexpression is an indicator of poor prognosis in SS.

Background: We aimed to compare two (plate-screws and locked intramedullary nail) biological internal fixation techniques in the treatment of adult femur shaft fractures., Methods: Group I included 28 patients operated with biological internal fixation with plate and screws. Group II consisted of 31 patients operated with locked intramedullary nailing technique. During the follow-up period in Group I, 1 patient died and 3 patients dropped out of the study, so the results of 24 patients were evaluated. During the follow-up period in Group II, 2 patients died and 3 patients dropped out of the study, so the results of 26 patients were evaluated in this group., Results: Age, sex, injury mechanism, fracture type, time to operation, duration of operation, amount of bleeding, fluoroscopy usage time, early and late complications, duration of hospitalization, fracture union time, and functional results of all patients were comparatively evaluated., Conclusion: According to our results, no superiority of either technique was demonstrated with respect to fracture union time, complication rate and functional results. Biological internal fixation with plate and screws is an alternative technique to locked intramedullary nailing in patients with multi-trauma or compromised pulmonary or cardiac function, or in complex comminuted or segmented diaphyseal or metaphyseal fractures.
