The reported incidence of complications following medial open-wedge high tibial osteotomy (MOWHTO) varies. The authors sought to assess the complications, additional surgeries, and joint survival following MOWHTO in patients with isolated medial compartment arthrosis during a mean follow-up of 10 years. This retrospective study involved patients implanted with spacer plates, angle adjustable plates, or inverse L-type plates with wedges between 2000 and 2010. A total of 504 knees from 441 patients were examined. Mean age of the study population was 52.6±7.0 years, with 56 (11.1%) knees from men and 448 (88.9%) from women. The 10-year Kaplan-Meier joint survival rate was 94.8%. Overall complication rate for MOWHTO was 63.7%, with complications in 20.3% of treated knees requiring additional surgery. In this population, although the overall complication rate and the need for additional surgery were high, the need for additional surgery resulting from serious complications was low (2.6%). The high joint survival rate and low rate of additional surgery for serious complications indicate that MOWHTO can be safely applied in patients with isolated medial gonarthrosis.

Background: The Talon™ DistalFix™ Proximal Femoral Nail (Talon-PFN) is a new proximal femoral intramedullary nail designed for the treatment of intertrochanteric femoral fractures. This study aimed to report the clinical and radiological outcomes of patients treated using a proximal femoral intramedullary nail with a novel design., Methods: Patients with either stable or unstable (AO/OTA type 31-A1, 2, 3) intertrochanteric fractures who were treated with the Talon-PFN between October 2014 and January 2018 in our department participated in this retrospective study. Patients' demographics, clinical characteristics, and functional and radiographical outcomes were evaluated., Results: A total of 110 patients (65 females, 45 males) with a mean age of 80.6 ± 9.1 years participated in this study. The mean follow-up time was 24 ± 13.4 months. The overall mortality rate during follow-up was 50.48%. The most common perioperative complications were a malposition of the femoral neck screw and talon cutout, both of which occurred in 17 patients (15.5%). The most common complications observed during follow-up were a lesser trochanter nonunion/malunion in 34 patients (30.9%), valgus malunion in 18 patients 16.4%), lateral screw migration in four patients (3.6%), and varus malunion in 15 patients (13.7%). A late screw cutout through the femoral head was seen in four patients (3.6%). At least one complication was detected in 53 patients (48.2%). However, revision surgery was performed in only six of these cases (5.5%)., Conclusion: According to the results obtained in this study, the Talon-PFN, which has similar clinical and radiological outcomes compared to other proximal femoral intramedullary nail designs according to the reported studies, can be a suitable alternative in the treatment of intertrochanteric fractures., Competing Interests: Declaration of Competing Interest There are no conflicts of interest associated with this article., (Copyright © 2020 Elsevier Ltd.

Our purpose is to evaluate the complications of open hip dislocation, which is used as a helpful technique in hip surgery. We have retrospectively reviewed 45 hips of 44 cases who applied open hip dislocation with various indications in our institute between the years 2006-2013. There were 27 males and 17 females whose mean age was 31,9 (range, 11-58) years with mean follow-up time of 56,9 months (range, 13-106). The number of cases with at least one complication related to open hip dislocation was 27. Within our series 14 hips have developed only 1 complication, 1 hip have 2, 10 hips have 3 and 2 hips have 4 different complications. Regarding Dindo-Clavien classification 17 hips were evaluated as Grade I (38%), 3 hips were Grade IIa (7%), 2 hips were Grade IIb (4%) and 5 hips were Grade III (11%). In conclusion, the absence of major complications after open hip dislocation does not make it absolutely safe. Open hip dislocations can only be indicated when trochanteric complications are considered. The patients need to be well informed on potential issues and risks.

Background: We aimed to determine the possible factors leading to re-operation in patients undergoing mechanical valve replacement and to investigate the relationship between valvular thrombus formation and mean platelet volume., Methods: The medical records of 43 patients with mechanical valve implantation, who were admitted to the Department of Cardiovascular Surgery of Dr Siyami Ersek Thoracic and Cardiovascular Surgery Training and Research Hospital between 2000 and 2005 were analysed retrospectively. Data recorded included demographic characteristics, valve type, size and location, implantation position, warfarin use, INR level, additional cardiac intervention, presence of left atrial thrombus, valvular thrombus, pannus formation, perivalvular leak, left atrial aneurysm, platelet count and mean platelet volume (MPV), bleeding after the primary surgery and/or revision of surgery due to other reasons, valve protection, aortic root expansion, presence of valve calcification and infective endocarditis, pre- and postoperative rhythm pattern, brand name of prosthesis, distance of the patient's house from a cardiac surgery centre, and concomitant noncardiac systemic diseases., Results: Mean age was 49.3 years (range 19-78 years). Of the patients, 51% (n = 22) were males and 49% (n = 21) were females. The re-operation mortality was 11.6%. Age, gender, valve type, brand of valve prosthesis, and implantation position were not risk factors for re-operation. The MPV was higher and statistically significant in patients with valvular thrombus during re-operation (p < 0.001). MPV was determined to be an independent risk factor with 85% sensitivity and 87% specificity., Conclusion: MPV and INR levels should be closely monitored when designing individualised postoperative medical treatment for patients undergoing heart valve re-operation.

Purpose: Pectus deformities and cardiac problems sometimes require simultaneous surgery. We report our experience of performing this surgery and review the relevant literature., Methods: We performed simultaneous pectus deformity correction and open-heart surgery in six patients between 1999 and 2006. The pectus deformities were pectus carinatum in one patient and pectus excavatum in five patients. The cardiac problems were coronary artery disease in one patient, an atrioseptal defect (ASD) with a ventricular septal defect (VSD) in one, a VSD in one, mitral valve insufficiency with left atrial dilatation in one, and an ascending aortic aneurysm with aortic valve insufficiency caused by Marfan's syndrome in two. We corrected the pectus deformities using the modified Ravitch's sternoplasty in all patients. First, while the patient was supine, we resected the costal cartilage; then, after completing the cardiac surgery, the sternum was closed and the additional time required for the pectus operation was calculated for each patient. Patients were examined 1, 4, and 6 months postoperatively., Results: The average operation time was 102 min, and there were no major complications. The pectus bars were removed 4-6 months postoperatively. Good cardiac and cosmetic results were achieved in all patients, who were followed up for 5 years., Conclusions: Concomitant pectus deformity correction and open-heart surgery can be performed safely, eliminating the risks of a second operation in a staged procedure.
