Comparative meta-analysis on the various vascularized bone flaps used for the treatment of scaphoid nonunion
(2017)We did a meta-analysis of the literature in order to clarify which of the vascularized bone flaps (VBF) used for scaphoid non-union treatment has the best outcome with regard to various parameters. We analyzed 54 articles ... -
Deep Learning for the Differential Diagnosis between Transient Osteoporosis and Avascular Necrosis of the Hip
(2022)Differential diagnosis between avascular necrosis (AVN) and transient osteoporosis of the hip (TOH) can be complicated even for experienced MSK radiologists. Our study attempted to use MR images in order to develop a deep ... -
Management of scaphoid nonunions with vascularized bone grafts from the distal radius: mid- to long-term follow-up
(2017)Scaphoid nonunion represents a challenging problem that leads to disability if neglected. Vascularized bone grafts are proposed to augment the local biology and increase the likelihood of union but long-term outcomes are ... -
MR angiogram confirms sustained blood flow in 1,2 ICSR artery of vascularized bone grafting in scaphoid nonunion treatment
(2019)Purpose: To evaluate the functioning of 1,2 intercompartmental supraretinacular artery (ICSRA) in vascularized bone grafting (VBG) of scaphoid nonunions with avascular necrosis of proximal pole. Materials and methods: ... -
MRI of the hip: Current concepts on bone marrow oedema
(2017)Bone marrow oedema (BME) is commonly found in hip MR imaging. BME is a nonspecific finding which can be related to a wide variety of diseases. However, there are cases where its existence or its pattern can narrow the ... -
Overestimation of the risk of revision with Kaplan-Meier presenting the long-term outcome of total hip replacement in older patients
(2018)Introduction: The purpose of the present study was (i) to review the long-term outcome of cemented Charnley total hip replacements (THRs) performed by 1 surgeon (GH), 20 to 42 years ago, in patients ≥60 years, using both ... -
Postacute sequelae of SARS-CoV-2 infection. Osteonecrosis must not be overlooked
(2022)Recovery from COVID-19 is not always uneventful, especially in critically ill hospitalized patients. Persistent symptoms including fatigue/ weakness, shortness of breath, anxiety, and depression have been described at ... -
Predictive role of cytokine gene polymorphisms for the development of femoral head osteonecrosis
(2012)Introduction: Osteonecrosis (ON) is a multifactorial disease that leads to hip destruction. Lately, much focus has been at femoral head preservation with nonsurgical methods. In this study we examined the polymorphisms of ... -
Radiomics and machine learning can differentiate transient osteoporosis from avascular necrosis of the hip
(2021)Differentiation between transient osteoporosis (TOH) and avascular necrosis (AVN) of the hip is a longstanding challenge in musculoskeletal radiology. The purpose of this study was to utilize MRI-based radiomics and machine ... -
The role of MR imaging in staging femoral head osteonecrosis
(2007)Reliability, accuracy and prognostic value of any classification system are important in evaluation and treatment of femoral head osteonecrosis. The purpose of the present study was to correlate the plain radiographs with ... -
Trabecular metal - Orthopaedic applications of a novel material
(2011)Unlike conventional porous-coated materials used in orthopaedic surgery, Trabecular Metal™ (TMT) is a novel material. It is made of tantalum with three-dimensional porosity throughout its volume resembling the structure ... -
White Matter Lesions in Femoral Head Osteonecrosis patients: Manifestation of vascular disease or not?
(2011)Background: Osteonecrosis has been associated with the presence of white matter lesions. The objective of this study was to investigate the association between macro- and micro-vascular disease and white matter lesions. ...
