Case Report A Surgical Opinion in a 36-Week Pregnant with Tibia Fracture: Intramedullary Nailing

The operative treatment of tibial fractures in late pregnancy is a controversial issue that is rarely discussed in the literature. Here we present a case of a tibial diaphyseal fracture in a woman that was 36 weeks pregnant, which was treated with intramedullary nails under noninvasive foetal monitoring with cardiotocography. The patient underwent a successful surgery, and no harm or adverse events to either the mother or the foetus were reported during or after the procedure. Following surgery, the mother had a comfortable pregnancy and a normal spontaneous vaginal delivery with a healthy newborn

Endoscopically Assisted Resection of a Rare Mass: Intra-Articular Osteochondroma of Shoulder Originated from Scapula

Osteochondromas are the most common benign bone tumors which are mostly seen in the metaphysis of distal femur, proximal tibia, and proximal humerus. As arising from flat bones such as scapula is a rare case, intra-articular osteochondroma is also rare. When the literature is searched it appeared that the scapula and shoulder joint are an uncommon site for osteochondroma. We present a case in which a patient had an osteochondroma placed in shoulder joint and originated from scapula which is a rare situation determined in the literature

Workability test method for metals applied to examine a workability measure (plastic limit) for clays

The Kure clay (KC) and the Deresakari clay (DC), taken from the Sogut region (Bilecik, Turkey), were examined by chemical analysis, X-ray diffraction (XRD) and thermal analysis techniques. It was determined that the KC and DC, whose basic clay mineral was kaolinite, contained 37% and 66% free quartz as mass percentage, respectively. The compression and upset tests applied to metals were applied to KC and DC. The KC and DC green bodies were passed through an extruder, and cylindrical clay green bodies having different moisture contents were obtained and used in the experiments. The yield stresses (sigma (0.2)) were determined from the compression tests. Plastic tensile strain limit values (epsilon (theta)*) were determined from the upset tests. The product of the two characteristic values, sigma (epsilon)(*)(0,2)(theta)(,) was defined as the workability. The variation of the sigma (0.2), epsilon (0)* and sigma (0.2)epsilon (theta)* values as a function of the moisture content of the green bodies was discussed for KC and DC. From the maxima of the sigma (0.2) curves, the optimum moisture percentages were determined as 22.0 and 26.5 for the KC and DC, respectively. These results and the results obtained from the Atterberg and Pfefferkorn tests were discussed comparatively

İzole Tip 2 Slap Lezyonu Nedeniyle Artroskopik Tamir Uygulanan Hastaların Kısa Dönem Klinik Sonuçlarının Değerlendirilmesi

Objective: The purpose of this study was to assess the clinical outcomes of isolated type IIsuperior labrum anteriorposterior (SLAP) lesions which were repaired arthroscopically Methods: The patientswho wereunderwent arthroscopic stabilization for isolated type IISLAP lesions werereviewed retrospectively. Shoulder function was evaluated according to the Constant-Murley score and visual analog scale (VAS) .Ranges of motion of the shoulders were evaluated both preoperatively and at the final follow-up. Results: A total of19 patients were evaluated. Of the patients; 15 were male and 4 were female and 31.5(23-45) was determined to be the mean age. Mean follow-up duration was 16.8 months (8-26). Preoperative mean Constant-Murley score was57 (40-71), whereas it was determined to be a mean of 81 (66- 98) at the final follow-up. VAS was determined to be 7(6-9) preoperatively, whereas it was determined to be 2 (0-5) at the final follow-up. Statistically significant differences were determined for both scoring systems at the final follow-up compared with the preoperative period(p<0.001). Conclusion: Arthroscopic repair ofisolated type II SLAP lesionsappeared as a reliable and effective procedure with respect to short-time clinical outcomes

Patellar Fixation With Suspensory Fixation Device in Single-Tunnel Medial Patellofemoral Ligament Reconstruction

The medial patellofemoral ligament (MPFL) is the primary soft-tissue stabilizer of the patellofemoral joint. Among the patellofemoral instability surgery options, MPFL reconstruction is the most preferred soft-tissue procedure. There is no gold-standard surgical treatment method in MPFL reconstruction, and many surgical methods have been described. We describe our surgical technique for MPFL reconstruction wherein the semitendinosus autograft is fixed to a single tunnel opened in the patella with a suspensory fixation device and only a single interference screw on the femoral side

Biomechanical Evaluation of a Novel Apatite-Wollastonite Ceramic Cage Design for Lumbar Interbody Fusion: A Finite Element Model Study

Objectives. Cage design and material properties play a crucial role in the long-term results, since interbody fusions using intervertebral cages have become one of the basic procedures in spinal surgery. Our aim is to design a novel Apatite-Wollastonite interbody fusion cage and evaluate its biomechanical behavior in silico in a segmental spinal model. Materials and Methods. Mechanical properties for the Apatite-Wollastonite bioceramic cages were obtained by fitting finite element results to the experimental compression behavior of a cage prototype. The prototype was made from hydroxyapatite, pseudowollastonite, and frit by sintering. The elasticmodulus of thematerial was found to be 32 GPa. Three intact lumbar vertebral segments were modelled with the ANSYS 12.0.1 software and this model was modified to simulate a Posterior Lumbar Interbody Fusion. Four cage designs in different geometries were analyzed in silico under axial loading, flexion, extension, and lateral bending. Results. The K2 design had the best overall biomechanical performance for the loads considered. Maximumcage stress recorded was 36.7MPa in compression after a flexion load, which was within the biomechanical limits of the cage. Conclusion. Biomechanical analyses suggest that K2 bioceramic cage is an optimal design and reveals essential material properties for a stable interbody fusion
