Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Hip arthroscopy after previous surgical hip dislocation for femoroacetabular impingement

, 2007
PURPOSE: The purpose of this study was to examine whether arthroscopic adhesiolysis can relieve symptoms of patients with persistent pain after open surgical hip dislocation for femoroacetabular impingement syndrome without osseous or cartilaginous ...

Open anterior hip dislocation in a young adult with exposed femoral head and no neurovascular damage [PDF]

, 2012
Anterior hip dislocation is common in younger adults and is the result of severe, high energy trauma such as high-velocity motor vehicle accidents or falls from great heights.

Surgical hip dislocation through a modified direct lateral approach: real-time perfusion monitoring

Arthroplasty Today, 2019
This study aimed to measure femoral head perfusion during hip resurfacing arthroplasty through a trochanter-sparing modified direct lateral approach. High-power laser Doppler probes were inserted into the femoral heads of 26 patients (26 hips, age range ...

Traumatic Hip Dislocation in Pediatric Patients: Clinical Case Series and a Narrative Review of the Literature with an Emphasis on Primary and Long-Term Complications

Children, 2023
Traumatic hip dislocation is a rare injury in pediatric populations. Dislocation may be associated with low-energy trauma, such as a minor fall. Traumatic hip dislocation is associated with severe complications, such as avascular necrosis of the femoral ...

Microstructure Modification of Additively Manufactured Mo–9Si–8B by Annealing and Its Effects on High‐Temperature Mechanical Properties

Advanced Engineering Materials, EarlyView.
Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

Recurrent and radiographically unrecognized iatrogenic intra‐prosthesis hip dislocations

Journal of the American College of Emergency Physicians Open, 2020
Hip dislocation is a common complication after total hip arthroplasty surgery. Newer prosthetic implants aim to reduce the risk of dislocation. The new dual mobility implant has a unique design that may result in intra‐prosthetic dislocation. We report a

Cryogenic Deformation Behavior of TiAl and Insights Into Embrittlement After High‐Temperature Exposure Combined With Secondary Ion Mass Spectroscopy of Near Surface Chemistry

Advanced Engineering Materials, EarlyView.
Near‐surface deuterium enrichment profiles for different microstructural types of TiAl after exposure at 700 °C in a heavy water‐containing environment. The deuterium levels are significantly higher than expected from natural occurrence, indicating that the heavy water dissociated during the exposure treatment and entered the specimens.

Salvage of dislocated hip and knee during limb lengthening for congenital femoral deficiency [PDF]

The Egyptian Orthopaedic Journal, 2017
BackgroundThe articular and soft tissue deficiencies associated with congenital femoral deficiency are reported to predispose to joint dislocation during limb lengthening, which would negate the value of limb lengthening.Patients and methodsThe cases of ...
