PURPOSE To evaluate a modified experimental model for medication-related osteonecrosis of the jaw (MRONJ) through the upper right central incisor extraction followed by intravenous bisphosphonate administration. METHODS Forty five rats underwent the upper right central incisor tooth extraction were divided in 2 groups: Group I - experimental group, 30 rats received an intravenous administrat...
Although postarthroscopic glenohumeral chondrolysis has become a well-known disastrous complication of arthroscopic shoulder surgery, little is known about postarthroscopic humeral head osteonecrosis. This article describes 3 patients who were referred to the authors' practice with end-stage osteonecrosis after an arthroscopic rotator cuff repair or debridement.Three patients (average age, 63.3...
BACKGROUND Osteonecrosis of the femoral head is a debilitating disease that involves impaired blood supply to the femoral head and leads to femoral head collapse. METHODS We use whole-exome sequencing and Sanger sequencing to analyse a family with inherited osteonecrosis of the femoral head and fluorescent Ca(2+) imaging to functionally characterise the variant protein. RESULTS We report a ...
Management of osteonecrosis of the jaw associated with antiresorptive agents is challenging, and outcomes are unpredictable. The severity of disease is the main guide to management, and can help to predict prognosis. Most available staging systems for osteonecrosis, including the widely-used American Association of Oral and Maxillofacial Surgeons (AAOMS) system, classify severity on the basis o...
Bisphosphonates are routinely used in the prevention and treatment of osteoporosis. Osteonecrosis of the jaw is known to be an important but rare complication of bisphosphonate usage. We present our experience with two patients of osteonecrosis of the jaw due to bisphosphonate usage.
PURPOSE This is a case study of a patient with multiple myeloma presenting with bisphosphonate-associated osteonecrosis of the jaw after an extraction of tooth #18 while receiving intravenous bisphosphonates. The class of drugs known as bisphosphonates is discussed. The patient's presenting signs and symptoms are reviewed. Bisphosphonate induced osteonecrosis definition, management and professi...
Our objective was to study the incidence, etiology, and diagnosis of multifocal osteonecrosis (MFON) and its treatment options to facilitate an earlier diagnosis and to optimize treatment. A radiological investigation was performed in osteonecrosis patients with a high risk of MFON for a more accurate diagnosis between January 2010 and June 2015. For patients with osteonecrosis of both the hip ...
This prospective study was aimed to evaluate the incidence of osteonecrosis in Thai patients with fracture neck of femur Forty-three patients who had sustained fracture were enrolled in the present study. The overall incidence of osteonecrosis was 72.1%. Incidence of osteonecrosis was 53.3% among patients who underwent surgery within 1 week after injury and 82.1% among those who underwent surge...
BACKGROUND AND PURPOSE Gaucher disease is heterogeneous. One of the most devastating complications is bone involvement, ranging from mild osteopenia to osteonecrosis, but no markers have been discovered to predict onset and/or progression. We describe our experience in a large referral center using drilling for juxta-articular osteonecrosis in young patients with Gaucher disease. PATIENTS AND...
The widespread use of MRI in the diagnosis of articular pathology has allowed for an improved knowledge of a series of disturbances that occur with epiphyseal bone edema as a main radiological sign, featured as low signal intensity of the bone marrow on T1 and high signal on STIR and fat saturated T2 sequences. The new etiopathogenic theories postulate a clear differentiation between primary an...
