Catheter-related bladder discomfort (CRBD) has been found in many patients with urologic surgery. The authors investigated the effect of analgesic-eluting urethral catheters on postoperative CRBD.

Patient safety regarding wrong site surgery has been one of the priority issues in surgical fields including that spine care. Since wrong-side DM foot patient was reported on a public mass media 1996, wrong-site issue attracted wide interest as safety. Despite many prevention campaigns care such operate through your initial program by Canadian Orthopaedic Association, sign American Academy Orthopedic Surgeon, sign, mark and X-ray North Spine Society, Universal Protocol Joint Commission,...

The objective of this study was to investigate the incidence osteonecrosis femoral head (ONFH) after cephalomedullary nailing in elderly patients with pertrochanteric fractures and analyze risk factors related ONFH.

Abstract The objective of this retrospective study was to investigate the surgical outcomes AO/OTA 31 A1-3 trochanteric fractures treated with new-generation Gamma3 nail U-Blade (RC) lag screw and analyze risk factors related fixation failure. A total 318 consecutive patients who underwent cephalomedullary nailing using for hip between September 2015 June 2018 were enrolled. average age 80 years most (69%) women. mean follow-up 12.2 months a minimum 6 months. 309 (97.2%) showed bony union...

This study aimed to compare the mechanical characteristics of four fixation methods including an anatomical suprapectineal quadrilateral surface (QLS) plate in hemipelvic models anterior column-posterior hemitransverse acetabular fractures typical elderly patients.In total, 24 composite were used and allocated groups: group 1, pre-contoured QLS plate; 2, reconstruction with two periarticular long screws; 3, a buttress 4, T-plate. Axial structural stiffness displacement each column fragment...

Antiplatelet medication has been frequently performed in elderly patients with hip fracture, because of comorbidities. This observational cohort study was to evaluate the effect continuous perioperative antiplatelet on outcomes after cephalomedullary nailing (CMN) a proximal femur fracture.One hundred and sixty-two consecutive aged ≥70 years undergoing CMN for fracture between January 2015 2017 were recruited. Of 162 patients, 47 (study group) taking antiplatelets preoperatively due...

High tibial osteotomy (HTO) is an effective alternative for medial compartmental knee osteoarthritis (OA). Circulating microRNAs (miRNAs) are known to serve as OA-related biomarkers. The present study investigated the differential expression of serum miRNAs before and after HTO identify potential prognostic miRNA-polymerase chain reaction (PCR) arrays were used screen in at preoperative 6-month postoperative time points from six patients, differentially expressed identified profiling stage...

There are concerns regarding nail/medullary canal mismatch and initial stability after cephalomedullary nailing in unstable pertrochanteric fractures. This study aimed to investigate the effect of an additional anteroposterior blocking screw on fixation fracture models with a short nail (CMN) fixation.Eight finite element (FEMs), comprising four different femoral diameters, without screws, were constructed, intertrochanteric fractures fixed CMNs reproduced all FEMs. Micromotions distal shaft...

Conflicting results have been reported regarding the factors that can predict discrepancy in coronal alignment of lower limb between radiographs taken standing and supine positions. Therefore, this study aimed to investigate discrepancies positions.We retrospectively evaluated medical records patients who underwent full-length anteroposterior both positions January 2019 September 2021.
