An increase in the risk of excessive femoral anteversion for relatively younger age and types of femoral morphology in total hip arthroplasty with direct anterior approach.
Direct anterior approach (DAA) is known to diminish a dislocation risk and widely used for total hip arthroplasty (THA). On the other hand, anterior dislocation due to increasing stem anteversion and cup anteversion is an important complication. ⋯ The risk of excessive femoral anteversion increases for relatively younger age and for types of femoral morphology according to the Dorr classification, moreover with an increase of CA in DAA-THA with cementless tapered-wedge stem.

After-hours elective spine deformity corrective surgery for patients with Adolescent Idiopathic Scoliosis: Is it safe?
The aim of this study was to compare the outcome of after-hours electively planned Posterior Spinal Fusion surgeries for Adolescent Idiopathic Scoliosis (AIS) patients with daytime surgeries. ⋯ After-hours elective spine deformity corrective surgeries for healthy ambulatory patients with AIS were as safe as when they were done during daytime.

Comparative StudyClinical outcomes of dual 3.5-mm locking compression plate fixation for humeral shaft fractures: Comparison with single 4.5-mm locking compression plate fixation.
Recently, several in vitro biomechanical studies that used dual small locking plate fixation for humeral shaft fractures have investigated. However, in vivo studies about dual plate fixation for humeral shaft fractures are limited. The purpose of our study was to report the outcomes of dual small plating for humeral shaft fractures in comparison with those of single large fragment plating. ⋯ For diaphyseal humeral fractures, dual 3.5-mm LCP fixation to the humerus is a possible treatment choice. This method showed satisfactory union rate, ROM, and complication rate, without increasing surgical time, in comparison with the conventional single 4.5-mm LCP fixation. Level of evidence: III.

Screw trajectory affects screw cut-out risk after fixation for nondisplaced femoral neck fracture in elderly patients.
Incidence of femoral neck fracture has risen with the aging of the population and has critical implications with regard to patient death, functional dependence, and social costs. Screw fixation using triangular configurations and calcar placement are still the preferred treatment for nondisplaced femoral neck fracture, to reduce the risk of loss of reduction and nonunion. However, this method is still controversial in terms of the effects of screw trajectory, including parallel or nonparallel configurations, on fixation of femoral neck fractures. This study aimed to compare the incidence of complications between patients who have undergone fixation with a parallel or a nonparallel screw trajectory. ⋯ Our results suggested that fixation with nonparallel screws for nondisplaced femoral neck fracture in elderly and osteoporotic patients might interfere with shortening of the femoral neck along with fracture healing, leaving patients at risk of postoperative screw cut-out from the femoral head.

The influence of the CT scan in the evaluation and treatment of nondisplaced femoral neck fractures in the elderly.
The management of nondisplaced femoral neck fractures (FNFs) has evolved, with emphasis in radiographic features such as posterior displacement. However, the role of advanced imaging in this scenario is still not well defined. Therefore, our objective is to assess the impact of a computed tomography scan (CT) on interobserver agreement (IA) of fracture classification, posterior tilt measurement, and treatment decisions in nondisplaced FNF in elderly patients. ⋯ IA for fracture classification and posterior tilt evaluation in nondisplaced FNF was not altered by the usage of a CT. There is improvement in treatment agreement when a CT scan is added to conventional imaging, with changes in treatment in 21% of cases.
