OBJECTIVE
The biological reaction to wear debris is critical to the osteolysis underlying aseptic loosening of joint prosthetic implants. In an attempt to reduce aseptic loosening, ceramics have been introduced. This study was designed to evaluate, compare and correlate the expression of Toll-like
To assess the natural evolution of the osseous reaction following arthroscopic double-row rotator cuff repair with PEEK anchors and to analyze its correlation with clinical shoulder function.Between 2015 and 2017, 159 patients received arthroscopic A 93-year-old man presented with a one-month history of persistent left hip pain of sudden onset. At first visit, radiographs revealed a fracture line at the medial portion of the acetabulum with no displacement. Magnetic resonance imaging revealed bone marrow edema in the corresponding medial
OBJECTIVE
The purpose of this study was to describe the MRI appearance in atraumatic osteolysis of the distal clavicle (AODC).
METHODS
We retrospectively evaluated MRI, medical records, ancillary diagnostic imaging studies and clinical course in five men and two women (mean age, 39 years) in whom
OBJECTIVE
To investigate the association between distal clavicular osteolysis and subchondral fractures of the distal clavicle at MRI.
METHODS
This study was approved by the hospital human research committee, which waived the need for informed consent. Three radiologists retrospectively analyzed 36
OBJECTIVE
Atraumatic distal clavicular osteolysis (DCO) has been described in adult male weightlifters. Our purpose was to investigate the frequency, magnetic resonance imaging (MRI) characteristics, risk factors, and long-term sequelae of DCO in young patients.
METHODS
Individuals with atraumatic
A 62-year-old man with a history of right total hip arthroplasty, who was managed conservatively for moderate osteolysis, presented with acute-onset, painless, significant, and diffuse right lower extremity edema. Initial laboratory markers were negative for infection. Advanced imaging demonstrated
The study objective was to determine the tissue response to polyethylene and/or titanium particles and the role that these play in peri-prosthetic osteolysis in a rabbit model of implant failure. Twenty-two mature rabbits were used. Unilateral tibial arthroplasty was performed on all of them. The
OBJECTIVE
The purpose of this work was to characterize the MR features of post-traumatic osteolysis of the distal clavicle in patients who have sustained a previous separation of the ipsilateral acromioclavicular (AC) joint.
METHODS
We studied eight male patients (mean age 25 years) with intractable
OBJECTIVE
To describe the MR imaging findings in patients with osteolysis of the distal clavicle and to compare the MR imaging appearance of clavicular osteolysis following acute injury with that related to chronic stress.
METHODS
MR imaging examinations were reviewed in 17 patients (14 men, 3
Background MRI with metal artifact reduction has gained importance in assessment of pain with total hip arthroplasty (THA). However, its role in diagnosis of periprosthetic joint infection (PJI) has not been well defined. Purpose To evaluate findings of PJI after THA and to determine the diagnostic
UNASSIGNED
The most common modes of failure of cemented unicompartmental knee arthroplasty (UKA) designs are aseptic loosening and unexplained pain at short- to mid-term follow-up, which is likely linked to early fixation failure. Determining these modes of failure remains challenging; conventional
BACKGROUND
A magnetic resonance imaging (MRI) scan of the shoulder can have added value in diagnosing symptomatic osteoarthritis of the acromioclavicular (AC) joint. Specific MRI signs have been recognized but not analyzed extensively before. This study aims to identify predictive MRI signs in
Retrospective chart review of patients who underwent anterior cervical discectomy and fusion (ACDF) using low-dose recombinant human bone morphogenic protein (rhBMP)-2.Determine whether severity and incidence of respiratory complications after ACDF surgery This study compared 3 composites made of hydroxyapatite and polyhydroxybutyrate to determine their biocompatibility, osteointegration, and osteoconduction in rabbits bone defects. Hydroxyapatite-polyhydroxybutyrate was tested in a 10:90 vol/vol ratio for composite 1, 25:75 for composite 2, and 50:50
