In Vivo Evaluation of Hemiarthroplasty Bearing Materials Using Animal Models: A Scoping Review (Part II)

Journal of Orthopaedic Research, Volume 44, Issue 1, January 2026.
ABSTRACT Hemiarthroplasty is commonly used to treat damage localized to one side of a synovial joint, maximally preserving the patient's opposing healthy bone and cartilage; however, challenges remain due to accelerated wear of the cartilage articulating with the implant surface. This scoping review summarized investigations of hemiarthroplasty bearing

Intestinal helminths as population markers of the Amazonian fish Mylesinus paraschomburgkii, with descriptions of five new genera and seven new species of trematodes [PDF]

, 1996
Helminths from the intestinal tracts of fish called "pacus" were studied. The fish were found only in rapids areas of Northeastern tributaries of the Amazon River.

Mechanical Evaluation of Posterior Wall Acetabular Facture Fixation: Patient‐Specific Implants Versus Conventional Implants

Journal of Orthopaedic Research, Volume 44, Issue 1, January 2026.
ABSTRACT The aim of the study was to design a standardized mechanical test setup and a corresponding finite element analysis to assess the stability and strength of both patient‐specific and conventional implants for posterior wall acetabular fractures.

Current Uses for Medical Imaging With Orthopaedic Implant Technology

Journal of Orthopaedic Research, Volume 44, Issue 1, January 2026.
ABSTRACT Musculoskeletal applications have been at the forefront of medical imaging since the first‐ever x‐ray was taken of a hand. Radiography remains routine in orthopaedics for surgical planning and diagnosing implant complications. Fluoroscopy is used to guide intra‐operative implant placement and to assess kinematics of different implants ...

Precision, Accuracy, and Observer Reliability of Computed Tomography‐Based Radiostereometric Analysis in Measuring Femoral Stem Migration In Vitro

Journal of Orthopaedic Research, Volume 44, Issue 1, January 2026.
ABSTRACT CT‐based radiostereometric analysis (CT‐RSA) is a method of measuring implant micromotion using low‐dose CT scans. We evaluated the precision, accuracy, and observer reliability of CT‐RSA for measuring femoral stem translation in THA in vitro.

Capsular management strategies in hip arthroscopy for femoroacetabular impingement syndrome: A multilevel meta‐analysis

Knee Surgery, Sports Traumatology, Arthroscopy, Volume 34, Issue 1, Page 284-308, January 2026.
Abstract Purpose To compare three capsular management strategies in hip arthroscopy (capsule preservation [CP], capsule repair [CR] and capsule unrepaired [CU]) for femoroacetabular impingement syndrome (FAIS). We hypothesized that CP and CR would provide superior outcomes compared with CU.

Impact of simultaneous exposure to RF and gradient electromagnetic fields on implant MR safety labeling

Magnetic Resonance in Medicine, Volume 95, Issue 1, Page 601-612, January 2026.
Abstract Purpose To investigate whether heating contributions produced by radiofrequency (RF) and gradient fields superpose sufficiently at the worst‐case locations to justify their simultaneous consideration in magnetic resonance imaging (MRI) implant safety labeling.

The acetabular blood supply: implications for periacetabular osteotomies [PDF]

, 2018
As the popularity of juxta-acetabular osteotomies in adults increases, concern arises that such a procedure will potentially cause avascular necrosis of the acetabular fragment.
