Avascular necrosis of the hip is a condition that results in necrosis that leads to bone collapse as a result of decreased blood supply to the bone. In hip avascular necrosis, which usually progresses with pain and limitation of movement, the aim is to protect the femoral head. Therefore, it is important to establish the diagnosis before the collapse of the femoral head. Various imaging methods are needed to diagnose the disease. Bone scintigraphy is a noninvasive imaging method. It is very sensitive in demonstrating bone lesions and is frequently used in diagnosing avascular necrosis. In our article, the role of nuclear imaging methods in the diagnosis of avascular hip necrosis is discussed.

Bone marrow aspirate concentrate (BMA) enhances the efficacy of core decompression (CD) which is the most commonly used surgery in the early stages of osteonecrosis with variable results. The purpose of the present study was to compare collapsed (stage IV) and noncollapsed patients (n: 30) that have osteonecrosis of the femoral head, in terms of variables, extent or stage of the lesion, pain scores, smoking habit, steroid usage. Demographic variables (age, sex), follow-up time, preop VAS, postop VAS, satisfaction point, frequency of smoking, and steroid usage, Ficat—Arlet stage were not different between collapsed (n: 24) and noncollapsed hips (n: 18) (p˃0.05). The only difference between the two groups was Kerbaul angle (p: 0.003), and necrotic index (p: 0.03), which were higher in collapsed patients (228±380 vs180±540, 38±13 Vs. 29±17).
Collapse or progress of disease mainly depends on the extent of the disease rather than demographic or etiologic factors, while collapsed patients report similar degrees of pain or satisfaction compared to non-collapsed patients.
