Avascular necrosis is the destruction of bone tissue as a result of a lack of blood flow. Alternative synonyms for this condition include osteonecrosis, aseptic necrosis, and ischemic bone necrosis. In dire cases, bone collapse may occur. It tends to affect the hip, shoulder, knee, hand, and foot. Other typical locations are the shoulder, knees, and ankles. Avascular necrosis is a clinical condition characterized by complaints such as localized discomfort and limited range of motion. Early conservative treatment helps to decrease the progression of the symptoms. In the initial stages of avascular necrosis, physiotherapy plays a crucial role to reduce pain and improve the range of motion. This case study aims to inform readers about the conservative treatment protocol that can manage avascular necrosis in the initial condition.

Avascular necrosis (AVN) is a known complication during the management of developmental dysplasia of the hip (DDH). It has the potential to alter the growth of the head or acetabulum and prevent the best outcomes. While past literature has evaluated the risks of AVN and strategies to avoid it, studies on the impact of AVN on the outcomes are scarce.

The early treatment of Osteonecrosis of Femoral Head (ONFH) remains a clinical challenge. Conventional Bone Marrow Mesenchymal Stem Cell (BMSC) injection methods often result in unsatisfactory outcomes due to mechanical cell damage, low cell survival and retention rates, inadequate cell matrix accumulation, and poor intercellular interaction. In this study, we employed a novel cell carrier material termed "3D Microscaffold" to deliver BMSCs, addressing these issues and enhancing the therapeutic effects of cell therapy for ONFH.

Background: Avascular necrosis (AVN) of the femoral head is a degenerative condition characterized by ischemic bone death, resulting in pain and impaired mobility. Core decompression, a surgical intervention, is widely performed for stage II AVN to alleviate symptoms and delay disease progression. While clinical and radiological outcomes are well-documented, the psychosocial dimensions of recovery remain underexplored.

Background: This study aims to evaluate the clinical outcome of biofluorescent imaging system (BIS) guided MRONJ surgery through analyzing 3D volumetric changes in CBCT data of bone structure.
Methods: BIS-guided surgery for MRONJ surgery was performed by grinding red-fluorescent area from remained residual bone detected by Qray-pen. CBCT data was collected preoperatively, postoperatively, and at last follow-up more than 3 months of each patient.

As life expectancy among patients infected with the human immunodeficiency virus (HIV) increases, a growing number of complications have been observed. This population displays an elevated risk of ischemic necrosis of the femoral head in comparison to the general population, which may be attributed to HIV infection, antiretroviral medication use, and hormone application. Patients infected with the human immunodeficiency virus (HIV) who also have necrosis of the femoral head tend to present at an earlier age, with a rapid disease progression and a high incidence of bilateral onset.
