Outcomes of a hydroxyapatite ceramic-coated femoral stem in primary total hip arthroplasty: a report of excellent survivorship from a single United Kingdom centre.

Background: Hydroxyapatite (HA) coated femoral stems were introduced to enhance the biological fixation at the implant-bone interface, aiming to increase the longevity and survival of the prostheses. We aimed to assess the long-term outcomes of an HA ceramic (HAC) coated stem in primary total hip arthroplasty (THA), assess the stem survival, and clinically evaluate the patients using patient-reported outcome measures (PROMs) and radiological evaluation of stem osseointegration.

Patients And Methods: This was a prospective evaluation of a retrospective cohort of 385 patients (442 hips) who underwent primary THA between June 2008 and December 2018.

Internal fixator external fixator in the management of unstable pelvic ring injuries: A prospective comparative cohort study.

Background: Reconstruction of the pelvic ring anatomy in unstable anterior pelvic ring injuries is a significant step to reduce the mortality rate associated with these injuries efficiently. There is a debate on using either an anterior subcutaneous pelvis internal fixator (INFIX) or an anterior supra-acetabular external fixator (EXFIX) to manage an unstable anterior pelvic ring fracture.

Aim: To compare the functional and radiological outcomes and complications of INFIX EXFIX in managing unstable pelvic ring injuries.

Minimally invasive stabilization of posterior pelvic ring injuries through transiliac internal fixator versus Iliosacral screw: A prospective comparative cohort study.

Introduction: Longitudinal sacral fractures are usually a matter of controversy regarding decision-making for reduction, fixation, and approach. Percutaneous and minimally invasive techniques present perioperative difficulties, but with fewer postoperative complications compared to open techniques. The objective of this study was to compare the functional as well as radiological outcomes of the Transiliac Internal fixator (TIFI) versus Iliosacral screw (ISS) fixation of sacral fractures applied percutaneously in a minimally invasive technique.

Does minimally invasive percutaneous transilial internal fixator became an effective option for sacral fractures? A prospective study with novel implantation technique.

Aim: To assess radiological and functional outcomes of transilial internal fixator (TIFI) for treatment of sacral complete transforaminal fractures with a novel implantation technique that decrease wound irritation problems in addition to facilitating easy application of reduction methods beside showing the best entry points, screw trajectories and angles.

Methods: A Prospective case series from 2019 to 2021 was conducted at university hospital including 72 patients with Denis type 2 sacral fractures. The operative and fluoroscopy time, reduction, implantation techniques, postoperative radiological and functional data were collected and evaluated with minimum follow-up of 12 months.

Minimally invasive sacroiliac fusion, a case series, and a literature review.

Introduction: Non-autoimmune sacroiliac joint pain contributes to nearly a quarter of low back pain patients. Non-surgical management fails to satisfy patients. A new minimally invasive technique for sacroiliac stabilization has been introduced, defying the traditional rules of fusion.

Safety of Transcatheter Aortic Valve Replacement in Patients with Aortic Aneurysm: A Propensity-Matched Analysis.

Introduction: There is a paucity of data regarding the outcomes of transcatheter aortic valve replacement (TAVR) among patients with thoracic or abdominal aortic aneurysms (AA). Using the Nationwide Inpatient Sample (NIS) database, we explored the safety of TAVR among patients with a diagnosis of AA.

Methods: We queried the National Inpatient Sample database (2012-2017) for hospitalized patients undergoing TAVR, using ICD-9 and ICD-10 codes for endovascular TAVR.

Coronary Artery and Pulmonary Artery Fistula: Rare Congenital Coronary Artery Fistula.

Coronary artery fistula is a rare condition that can be congenital or acquired. Most patients with these anomalies remain asymptomatic, but symptoms and complications may develop with increasing age. We discuss the clinical presentation, diagnostic work-up, and management options for this condition.

Single versus double column fixation in transverse fractures of the acetabulum: A randomised controlled trial.

Introduction: Biomechanical studies have compared fixation methods in transverse acetabular fractures, yet there is not enough clinical data to suggest an optimal fixation method. The aim of this randomized controlled trail was to compare fracture stability in posterior plating alone versus posterior plating and anterior column lag-screw fixation in treatment of transverse and transverse with posterior wall acetabular fractures.

Methods: Thirty patients were randomized to one of two groups, either posterior fixation alone (single column group), or posterior plating and anterior fixation with percutaneous anterior column screw (double column group).

Quadrilateral plate fractures of the acetabulum: Proposition for a novel classification system.

Background: Currently, there is no definition or classification system for quadrilateral plate (QLP) fractures; the aim was to anatomically and radiologically characterise the QLP, propose a definition and classify QLP fractures.

Methods: This study included an anatomical component and a radiological component. The anatomical study aimed at defining the characteristics of the QLP; the QLP was identified using four articulating bony pelvis specimens.
