Purpose: Extraction of the distal femoral cement mantle and restrictor during revision total hip arthroplasty (rTHA) is challenging and can compromise host bone stock. The aim of this study is to report outcomes of our femoral windowing technique for cement removal.
Methods: We report on a cohort of 36 patients with an average age of 68.7 years who underwent 40 cemented rTHA between 2011 and 2017 using a vascularised anterior femoral window. Clinical and radiological outcomes were retrospectively reviewed with a mean follow-up of 6.6 years (range, 3.8-10).
Results: Latest mean WOMAC score was 25.4 and all windows achieved radiographic union by a mean of 7.9 weeks. Femoral component survivorship was 100% and 38 out of 40 rTHAs showed no evidence of radiological loosening.
Conclusion: The vascularised anterior window to remove the distal femoral cement mantle under direct vision is safe and reproducible with excellent clinical and radiographic results.

Identifying a Reliable Intra-articular Landmark to Avoid Vascular Injury During Transacetabular Screw Fixation: A 3D Computed Tomography Study.
J Am Acad Orthop Surg

Introduction: Vascular injury during acetabular screw fixation is a life-threatening complication of total hip arthroplasty. This study uses three-dimensional computed tomography to (1) measure absolute distance from the external iliac artery (EIA) to the acetabulum, (2) determine available bone stock along the EIA path, and (3) create a novel acetabular vascular risk map.
Methods: A retrospective radiographic study was conducted using three-dimensional CT.
Relationship Between Pituitary Gland and Stem Cell in the Aspect of Hormone Production and Disease Prevention: A Narrative Review.
Endocr Metab Immune Disord Drug Targets

Amity Institute of Pharmacy, Amity University Haryana Chemistry Gurugram India.
Objectives: In the last two decades, scientists have gained a better understanding of several aspects of pituitary development. The signaling pathways that govern pituitary morphology and development have been identified, and the compensatory relationships among them are now known.
Aims: This paper aims to emphasize the wide variety of relationships between Pituitary Gland and Stem cells in hormone Production and disease prevention.
Most thoracic aortic aneurysms (TAAs) are asymptomatic and often diagnosed at the time of rupture. TAAs involving the proximal arch require adequate coverage with thoracic endovascular aortic repair, which is timely and challenging in emergent ruptures. In situ laser fenestration is a novel method of arch revascularization.

Background And Purpose: Prolonged venous transit (PVT), derived from computed tomography perfusion (CTP) time-to-maximum (T) maps, reflects compromised venous outflow (VO) in acute ischemic stroke due to large vessel occlusion (AIS-LVO). Poor VO is associated with worse clinical outcomes, but pre-treatment markers predictive of PVT are not well described.
Methods: We conducted a retrospective analysis of 189 patients with anterior circulation AIS-LVO who underwent baseline CT evaluation, including non-contrast CT, CT angiography, and CTP.
Comparison between ruptured anterior choroidal artery aneurysms and ruptured intracranial aneurysms in other locations in relation to aneurysm dimensions at rupture.

Purpose: It was noticed that anterior choroidal artery (AChoA) aneurysms appear to rupture at relatively smaller sizes compared with aneurysms in other intracranial locations, based on anecdotal clinical experience. We therefore aimed to compare ruptured AChoA aneurysms with other ruptured aneurysms in other intracranial locations, pertaining to aneurysm dimensions. This may help in finding out if the rupture risk stratification, based on the amalgamation of aneurysms of multiple locations in one group, precisely estimates aneurysm rupture risk.
