Symptoms and diagnosis
AVN may present with groin pain during activity or at rest. MRI is sensitive in early disease, while radiographs help identify collapse and later degenerative change.
Why stage matters
Treatment differs substantially before and after femoral-head collapse. Lesion size and location also influence prognosis and management.
Joint-preservation options
In selected pre-collapse cases, core decompression may be considered, with or without adjunctive biologic techniques depending on the clinical situation and evidence.
When is hip replacement appropriate?
Once substantial collapse or secondary arthritis has developed with significant symptoms, total hip replacement is often the more predictable reconstructive option.
Risk factors
AVN can be associated with corticosteroid exposure, heavy alcohol use, certain blood disorders or trauma, although some cases are idiopathic.
Frequently Asked Questions
Does AVN always lead to hip replacement?
No. Stage, lesion size, location and symptoms matter, and selected early-stage cases may be suitable for joint-preservation treatment.
Is MRI necessary?
MRI is particularly useful when radiographs are normal or equivocal but clinical suspicion remains high.
Individualized Care
Treatment recommendations depend on symptoms, examination, imaging, activity demands and patient goals rather than any single test result.
