Dual Mobility in Extreme Situations of Revision Hip Arthroplasty: A Case Series of 3 Cases and Review of Literature.
J Orthop Case Rep
December 2024
Department of Orthopaedics, Seth GS Medical College and KEM Hospital, Mumbai, Maharashtra, India.
Introduction: Dual mobility (DM) total hip replacement (THR) features an acetabular component with an unconstrained tripolar build which ensures a greater range of motion without provoking any dislocation.We report three cases with extremes of surgical misadventure where we carried out a revision arthroplasty with a DM cup. The causes of the failure of the primary arthroplasty were multifactorial, even individually, and ranged from instability due to component malposition, trochanteric fracture, intrapelvic prosthesis protrusion, etc.

Article Synopsis
- * Certain medications, like tacrolimus, used in patients post-liver transplantation, can increase the risk of developing peripheral nerve issues.
- * This case study illustrates early EMG findings for a patient on tacrolimus who experienced a reversible brachial plexopathy, emphasizing that such injuries may not always involve axonal damage.
Central venous catheter insertion profile and complications among neonates in Saudi Arabia: a cross-sectional study.
BMJ Open
November 2024
Department of Pediatrics, College of Medicine, Imam Mohammad Ibn Saud Islamic University, Riyadh, Saudi Arabia
Objectives: To compare complications in neonates who had umbilical venous catheter (UVC) versus peripherally inserted central catheter (PICC), percentage of non-elective removal of central catheters, and to compare complications of PICC in the upper limb compared with the lower limb.
Design: A prospective cross-sectional cohort study.
Setting: Neonatal intensive care unit (NICU) in Prince Sultan Military Medical City in Riyadh, Saudi Arabia.
Linear and Volumetric Polyethylene Wear Patterns after Primary Cruciate-Retaining Total Knee Arthroplasty Failure: An Analysis Using Optical Scanning and Computer-Aided Design Models.
Materials (Basel)
October 2024
Valdoltra Orthopaedic Hospital, Jadranska cesta 31, 6280 Ankaran, Slovenia.
(1) Background: Analyses of retrieved inserts allow for a better understanding of TKA failure mechanisms and the detection of factors that cause increased wear. The purpose of this implant retrieval study was to identify whether insert volumetric wear significantly differs among groups of common causes of total knee arthroplasty failure, whether there is a characteristic wear distribution pattern for a common cause of failure, and whether nominal insert size and component size ratio (femur-to-insert) influence linear and volumetric wear rates. (2) Methods: We digitally reconstructed 59 retrieved single-model cruciate-retaining inserts and computed their articular load-bearing surface wear utilizing an optical scanner and computer-aided design models as references.

J Orthop Case Rep
September 2024
Department of Orthopaedics, AIIMS, Bhubaneswar, Odisha, India.
Article Synopsis
- * A 63-year-old man with cervical myelopathy experienced neurological decline after decompression surgery, which was confirmed by MRI showing significant cervical cord edema, despite there being no issues with the surgical implants.
- * It's crucial for spine surgeons to consider and discuss WCS when patients exhibit unexplained neurological deterioration after surgery, as the underlying mechanisms and appropriate treatments for WCS are still not well understood, raising ethical and legal concerns.
