MRI of Total Hip Arthroplasty: Successful Ripple Artifact Reduction Using Wavelet Domain Filtering

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Slice encoding for metal artifact correction (SEMAC) is used in MRI for total hip arthroplasties for metal artifact reduction. However, ripple artifacts often arise near the implant, impairing diagnosis in affected regions. Hypothesis Applying a wavelet domain filter (WD‐Filter) might reduce ripple artifacts and improve image ...

Performance of the resurfaced hip. Part 2: the influence of prosthesis stem design on remodelling and fracture of the femoral neck [PDF]

, 2010
Hip resurfacing is a popular treatment for osteoarthritis in young, active patients. Previous studies have shown that occasional failures – femoral neck fracture and implant loosening, possibly associated with bone adaptation – are affected by prosthesis

Valproic Acid Inhibits Ferroptosis and Improves Bone Integration in OVX Rats Through the AMPK/SIRT1 Pathway

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT The prevalence of postmenopausal osteoporosis (PMOP) has been steadily increasing. Ferroptosis has been recognized as a critical factor influencing the bone‐forming ability of bone marrow mesenchymal stem cells (BMSCs). Valproic acid (VPA), an HDAC inhibitor, has been suggested to play a role in regulating osteoporosis development; however ...

Formation of a large rice body-containing cyst following total hip arthroplasty

BMC Research Notes, 2012
Background There are several well-described causes of a painful mass following total hip arthroplasty including polyethylene and metal wear debris, infection, expanding hematoma, dislocation, and synovial cysts. In addition to causing pain, these lesions,

Patients with previous anterior cruciate ligament reconstruction achieve equally good outcomes after total knee arthroplasty: A Swedish registry‐based study of 7755 patients

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Patients who have undergone anterior cruciate ligament reconstruction (ACLR) may later require total knee arthroplasty (TKA) due to osteoarthritis (OA). The impact of previous ACLR on patient‐reported outcomes (PROs) after TKA remains uncertain.

Assessing the material loss of the modular taper interface in retrieved metal on metal hip replacements [PDF]

, 2015
Measuring the amount of material loss in the case of revised hip replacements is considered to be a prerequisite of understanding and assessing the true in vivo performance of the implant.
