Avascular Necrosis Treatment in Missouri
Find orthopedic specialists who treat avascular necrosis in Missouri
Avascular necrosis (AVN), also called osteonecrosis, is the death of bone tissue due to loss of blood supply. Without adequate blood flow, the bone cells die and the bone structure collapses over time. The femoral head - the ball of the hip joint - is the most commonly affected site, but the knee, shoulder, and ankle can also be involved. AVN ranges from early-stage disease with no collapse (often manageable with joint-preserving procedures) to late-stage collapse requiring joint replacement.
Common symptoms of avascular necrosis
- Groin pain that comes on gradually, often without a clear injury
- Pain that worsens with weight bearing and activity
- Limited range of hip motion
- Pain at night in more advanced stages
- Limping to offload the affected hip
When to see a specialist
See an orthopedic specialist promptly if you have risk factors (corticosteroid use, alcohol use, prior hip trauma, sickle cell disease, or history of decompression sickness) and develop hip or groin pain. Early-stage AVN is detected on MRI before collapse - and early intervention preserves more options. Once the bone collapses, joint-preserving treatments become less effective.
Treatment options
Activity modification and protected weight bearing
For early small lesions in non-weight-bearing areas of the femoral head. Crutches to reduce load while the area is monitored.
Core decompression
A drill is passed into the femoral head to reduce intraosseous pressure and stimulate new blood vessel growth. Most effective in early stages before collapse. Often combined with bone graft or stem cell therapy.
Bone grafting and vascularized fibula
For patients with pre-collapse disease: a vascularized bone graft (often from the fibula) is implanted to provide structural support and a new blood supply. Complex procedure with variable outcomes.
Total hip replacement
For patients with femoral head collapse and pain. The standard treatment for late-stage AVN. Highly effective at relieving pain and restoring function.
Recovery timeline
Depends entirely on stage. Core decompression: 6-8 weeks on crutches, 3-6 months for full recovery. Total hip replacement for collapsed AVN: 3-6 months for full recovery. Early intervention consistently produces better outcomes.
