The Use of Computer Navigation in Total Hip Arthroplasty Is Associated with a Reduced Rate of Revision for Dislocation: A Study of 6,912 Navigated THA Procedures from the Australian Orthopaedic Association National Joint Replacement Registry.

Background: The use of computer navigation has been shown to produce more accurate cup positioning when compared with non-navigated total hip arthroplasty (THA), but so far there is only limited evidence to show its effect on clinical outcomes. The present study analyzed data from the Australian Orthopaedic Association National Joint Replacement Registry to assess the impact of computer navigation on the rates of all-cause revision and revision for dislocation following THA.

Methods: Data for all non-navigated and navigated primary THAs performed for osteoarthritis in Australia from January 1, 2009, to December 31, 2019, were examined to assess the rate of revision.

Review of orthopaedic trauma surgery during the peak of COVID-19 pandemic - An observational cohort study in the UK.

Aim: This study aims to estimate the risk of acquiring medical complication or death from COVID-19 infection in patients who were admitted for orthopaedic trauma surgery during the peak and plateau of pandemic. Unlike other recently published studies, where patient-cohort included a more morbid group and cancer surgeries, we report on a group of patients who had limb surgery and were more akin to elective orthopaedic surgery.

Methods: The study included 214 patients who underwent orthopaedic trauma surgeries in the hospital between 12th March and 12th May-2020 when the pandemic was on the rise in the United Kingdom.

Extensor Carpi Radialis Longus Tenodesis Using a Biotenodesis Screw for Treatment of Symptomatic Geissler 2 Scapholunate Dissociation.

Treatment of scapholunate dissociation (SLD) depends on the degree of injury. We present our technique of extensor carpi radialis longus (ECRL) tenodesis for Geissler grade 2 SLD and our preliminary results. After arthroscopic confirmation of Geissler grade 2 SLD, we use a single incision and a polyetheretherketone (PEEK) anchor, attaching half of the ECRL tendon to the scaphoid.

Walking impairments after severe tibia plateau fractures. A gait pattern analysis.

Purpose: Tibia plateau fractures are severe knee injuries which have a great impact on the patients' lives, but in what extend is not clear yet in the literature. The purpose of this study was to investigate the short-term gait alternations after severe tibia plateau fractures treated with circular Ilizarov frame.

Materials & Methods: Gait pattern evaluation was performed to patients who were treated with circular Ilizarov frame after severe tibia plateau fractures (Schatzker IV-VI), three to six months after the frame removal.

Chertsey Outcome Score for Trauma: Development and validation of a new unifying patient reported outcome measure for orthopaedic trauma.

Purpose: Lately there is an increasing tendency of using Patient Reported Outcome Measures (PROMs) as a final indicator of the outcome of many surgical treatments in orthopaedics and in other medical specialties. Currently there are many outcome scores in orthopaedics and most of them are site specific. In the contrary there is a lack of trauma specific outcome scores.
