Diagnostic Performance of Ultrasound to Evaluate Mild Hip Osteoarthritis: Comparison With Radiography and MRI

Journal of Clinical Ultrasound, EarlyView.
A moderate‐sized femoral neck osteophyte (white arrow) in US (A), anteroposterior CR (B), and MRI (C). Additional osteoarthritis‐related changes (arrowheads) are visible in CR and MR, but not in US. US and CR demonstrated similar moderate diagnostic capability to detect mild hip osteoarthritis and were associated with increased hip pain.

Corrosion in Modular Revision Hip Stem Tapers – A Retrieval Analysis

Journal of Orthopaedic Research, EarlyView.
ABSTRACT In revision hip arthroplasty, modular stems enable intraoperative adjustment of the biomechanics of the hip to ensure a stable joint function even in complex anatomical cases. Modular stem junctions, however, carry the risk of junction degradation due to corrosive processes or even junction breakage.

Trunnionosis in total hip arthroplasty: a review

Journal of Orthopaedics and Traumatology, 2016
Trunnionosis is defined as wear of the femoral head–neck interface and has recently been acknowledged as a growing cause of total hip arthroplasty failure. Some studies have reported that it accounts for up to 3 % of all revisions.

A new mini-navigation tool allows accurate component placement during anterior total hip arthroplasty. [PDF]

, 2018
Introduction: Computer-assisted navigation systems have been explored in total hip arthroplasty (THA) to improve component positioning. While these systems traditionally rely on anterior pelvic plane registration, variances in soft tissue thickness ...

Scintigraphic assessment of bone status at one year following hip resurfacing : comparison of two surgical approaches using SPECT-CT scan [PDF]

, 2012
Objectives: To study the vascularity and bone metabolism of the femoral head/neck following hip resurfacing arthroplasty, and to use these results to compare the posterior and the trochanteric-flip approaches.

The Importance of Modeling Press‐Fit to Accurately Evaluate Interfacial Micromotion as an Indicator of Primary Stability in Uncemented Arthroplasty

Journal of Orthopaedic Research, EarlyView.
ABSTRACT Arthroplasty is most often performed to alleviate pain and restore function in patients with end‐stage degenerative joint disease. Uncemented implant fixation is increasingly used in total knee and total ankle arthroplasty. Implantation using interference press‐fit is a manufacturer‐recommended guideline for achieving stable primary fixation ...

Muscle activation pattern during gait and stair activities following total hip arthroplasty with a direct anterior approach: a comprehensive case study

Arthroplasty Today, 2018
Muscle activation following total hip arthroplasty with a direct anterior approach has not previously been reported in the literature. This case report details the electromyography outcome of a 60-year-old male patient with unilateral direct anterior ...

Evaluation of range of motion restriction within the hip joint [PDF]

, 2012
In Total Hip Arthroplasty, determining the impingement free range of motion requirement is a complex task. This is because in the native hip, motion is restricted by both impingement as well as soft tissue restraint. The aim of this study is to determine

Short-Term Radiographic Evaluation of a Tri-Tapered Femoral Stem in Direct Anterior Total Hip Arthroplasty [PDF]

, 2020
Introduction. Direct anterior approach (DAA) total hip arthroplasty (THA) has become increasingly popular, largely due to utilization of a true internervous and intermuscular plane. However, recent literature has demonstrated an increased rate of femoral

Frontiers in the Management of Orthopaedic Periprosthetic Joint Infection

Journal of Orthopaedic Research, EarlyView.
ABSTRACT Periprosthetic joint infection (PJI) is a devastating complication of total joint arthroplasty (TJA), one of the most frequently performed surgical procedures worldwide. Management of acute PJI commonly involves debridement, antibiotics, and implant retention (DAIR), though failure rates remain high due to antibiotic‐tolerant biofilms. Chronic
