Evaluation of Femoral Head Avascular Necrosis With Virtual Noncalcium Dual-Energy Computed Tomography.

Objective: Our aim was to investigate the effectiveness of the dual-energy computed tomography (DECT) virtual noncalcium (VNCa) technique in avascular necrosis (AVN) for detecting bone marrow edema (BME) and staging.

Methods: This prospective study included adult patients diagnosed with unilateral or bilateral femoral head AVN between January 2023 and December 2023, who had magnetic resonance imaging (MRI) and DECT. Two participants were excluded from the study due to undergoing surgical procedures during the period between the scans.

Mean S1 inlet and outlet view angles are not safe for all individuals according to three-dimensional tomographic measurements.

Although there are many studies evaluating optimal inlet and outlet angles required for the correct placement of S1 iliosacral screws, there is no study evaluating reliability and feasibility of these angles for all individuals on three-dimensional (3D) anatomical models. A total of 100 women and 100 men were selected randomly. A vertical line was created according to long axis of the tomography device on which patient was lying in supine position.

TT-TG distance decreases after open wedge distal femoral varization osteotomy in patients with genu valgum & patellar instability. A pilot 3D computed tomography simulation study.

Background: Genu valgum is considered to be a risk factor for patellar instability. Correction of valgus alone or combined with a tibial tuberosity medialization has been described. However, changes occurring in the tibial tuberosity-trochlear groove (TT-TG) distance after a lateral distal femoral opening wedge osteotomy (LDF-OWO) are not known.

Incidence and Factors Associated With Pulmonary Embolism After Upper Extremity Trauma: A Tertiary Hospital Experience in Turkey.

Introduction Venous thromboembolism (VTE), particularly pulmonary embolism (PE), is the third highest cause of death in trauma patients who survive beyond the first day. Musculoskeletal surgery is associated with several complications, some of which may be life-threatening, including deep vein thrombosis (DVT) and PE. Objective This research aims to describe risk variables for VTE after upper extremity (UE) fracture at a single institution and estimate the incidence of PE following UE fracture.

Comparison of open reduction alone and open reduction plus Dega osteotomy in developmental dysplasia of the hip.

In the treatment of developmental dysplasia of the hip, concentric reduction of the femoral head into the acetabular cavity plays a key role in the natural development of the acetabulum. However, there is still debate on the need for additional acetabular osteotomies and their timing. In this study, we compared open reduction (OR) alone with OR plus Dega osteotomy for acetabular index (AI) development.

Chondroprotective effects of a new glucosamine combination in rats: Gene expression, biochemical and histopathological evaluation.

Aims: This study investigates the effect of a new combination of glucosamine hydrochloride, chondroitin sulfate, methylsulfonylmethane, Harpagophytum procumbens root extract (standardized to 3% harpagoside) and bromelain extract (GCMHB) on formalin-induced damage to cartilage tissue in the rat knee joint and evaluates this combination in comparison with another combination of glucosamine hydrochloride, chondroitin sulfate and methylsulfonylmethane (GKM).

Materials And Methods: Animals in the control group were injected with formalin into the knee joint (FCG). Animals in the GCMHB-500 group were given 500mg/kg GCMHB+formalin, and those in the GKM-500 group were given 500mg/kg GKM+formalin.

Recurrent anterior shoulder instability: Review of the literature and current concepts.

The purpose of this review article is to discuss the clinical spectrum of recurrent traumatic anterior shoulder instability with the current concepts and controversies at the scientific level. Because of increasing participation of people from any age group of the population in sports activities, health care professionals dealing with the care of trauma patients must have a thorough understanding of the anatomy, patho-physiology, risk factors, and management of anterior shoulder instability. The risk factors for recurrent shoulder dislocation are young age, participation in high demand contact sports activities, presence of Hill-Sachs or osseous Bankart lesion, previous history of ipsilateral traumatic dislocation, ipsilateral rotator cuff or deltoid muscle insufficiency, and underlying ligamentous laxity.
