COVID-19 hip fracture outcomes: The role of Ct values and D-dimer levels?

Introduction: The COVID-19 pandemic has caused high mortality rates in hip fracture patients, but data for Asian patients are lacking. Whilst Cycle threshold (Ct) values and D-dimer have been reported as predictors of mortality in COVID-19 patients, their prognostic roles in those with concomitant hip fracture remain unknown. The objectives of this study were to i) assess the clinical outcomes of COVID-19 hip fractures patients in the Chinese population, ii) identify risk factors of mortality and complications, and iii) determine the prognostic roles of Ct values and D-dimer levels.

Surgical accuracy of image-free versus image-based robotic-assisted total knee arthroplasty.

Background: This study investigated the accuracy in achieving proper lower limb alignment and component positions after total knee replacement (TKR) with image-free and image-based robotic-assisted TKR.

Methods: A total of 129 patients (166 knees) suffering from end-stage knee arthritis who underwent TKA operated by robotic-assisted surgery between the years 2018 and mid-2021 were recruited. Radiological outcomes were compared between image-free and image-based robotic-assisted surgical systems.

Should nails be locked dynamically or statically in atypical femoral fractures? - A radiological analysis of time to union and reoperations in 236 displaced fractures with 4 years average follow-up.

Introduction: Atypical femoral fractures (AFFs) are associated with delayed union and higher reoperation rates. Axial dynamization of intramedullary nails is hypothesized to reduce time-to-union (TTU) and fixation failure as compared to static locking.

Methods: Consecutive acutely displaced AFFs fixed with long intramedullary nails across five centres between 2006 and 2021 with a minimum postoperative follow-up of three months were retrospectively reviewed.

A Toolbox of Bone Consolidation for the Interventional Radiologist.

Bone consolidation is increasingly used in the treatment of both benign and malignant bone conditions. Percutaneous vertebroplasty, for example, has been shown to be useful in vertebral compression fractures in the VAPOUR trial which showed its superiority to placebo for pain reduction in the treatment of acute vertebral compressive fractures. Further tools have since been developed, such as kyphoplasty, spinal implants, and even developments in bone cements itself in attempt to improve outcome, such as chemotherapy-loaded cement or cement replacements such as radio-opaque silicon polymer.

Surgeon-designed patient-specific instrumentation improves glenoid component screw placement for reverse total shoulder arthroplasty in a population with small glenoid dimensions.

Purpose: Glenoid component loosening is a potential complication of reverse total shoulder arthroplasty (rTSA), occurring in part due to lack of adequate screw purchase in quality scapular bone stock. This study was to determine the efficacy of a surgeon-designed, 3D-printed patient-specific instrumentation (PSI) compared to conventional instrumentation (CI) in achieving longer superior and inferior screw lengths for glenoid component fixation.

Methods: A multi-centre retrospective analysis of patients who underwent rTSA between 2015 and 2020.

Orthogeriatric Multidisciplinary Co-Management Across Acute and Rehabilitation Care Improves Length of Stay, Functional Outcomes and Complications in Geriatric Hip Fracture Patients.

Introduction: As the global number of geriatric hip fracture cases continues to proliferate, a newly developed orthogeriatric co-management multidisciplinary care model has been implemented since November 2018 to meet further increases in demand. Our objective was to evaluate the effectiveness of the new pathway in improving the clinical outcomes of fragility hip fractures.

Methods: The data of geriatric hip fracture patients from 1 April 2018 till 30 October 2018 was collected as the conventional orthopaedic care model (pre-orthogeriatric care model) to compare with data from the orthogeriatric co-management model, 1 Feb 2019 till 31 August 2019.

Topical administration of tranexamic acid in elderly patients undergoing short femoral nailing for intertrochanteric fracture: A randomised controlled trial.

Introduction: Topical application of tranexamic acid (TXA) has been proposed as an alternative to intravenous administration to reduce perioperative bleeding in orthopaedic surgery. The purpose of this randomised controlled trial was to evaluate the efficacy and safety of 1 g topically applied TXA in patients undergoing fixation of intertrochanteric hip fractures by short femoral nailing.

Methods: A total of 121 patients were enrolled between May 2018 and January 2020.

Comparing 3 Different Techniques of Patella Fracture Fixation and Their Complications.

Introduction: Patella fractures managed by fixation with metal implants often cause local soft tissue irritation and necessitate implant removal. An alternative is to utilize suture-based fixation methods. We have adopted suture and hybrid fixation in the routine management of patella fractures.
