Core Decompression for Avascular Necrosis

Core decompression relieves pressure in the femoral head to treat early avascular necrosis, preserving the hip joint before collapse occurs.

Joint-Preserving Treatment for Early AVN

Core Decompression is a minimally invasive procedure performed to treat early-stage avascular necrosis (AVN) of the hip before the femoral head collapses. The procedure involves drilling into the dead bone to relieve pressure and stimulate new blood vessel growth.

AVN occurs when the blood supply to the femoral head is interrupted, causing bone death. If left untreated, the dead bone weakens and the femoral head collapses, leading to severe hip arthritis requiring joint replacement. Core decompression is most effective when performed early, before collapse occurs.

At Mountain Spine & Orthopedics, our hip specialists use advanced imaging including MRI to detect AVN in its early stages. When appropriate, core decompression can preserve the hip joint and prevent the need for joint replacement, making early diagnosis and treatment crucial.

Ideal Candidates for Core Decompression

  • Patients with early-stage avascular necrosis before femoral head collapse
  • Those with AVN detected on MRI but minimal symptoms
  • Younger patients who want to preserve their natural hip joint
  • Individuals with small areas of bone death (less than 30% of femoral head)
  • Patients without significant collapse or deformity of the femoral head
  • Those who understand the importance of early intervention
  • Patients willing to follow post-operative restrictions to protect the healing bone

The Core Decompression Process

  1. Small incisions are made to access the greater trochanter (bony prominence on the femur)
  2. A specialized drill is used to create channels into the dead bone in the femoral head
  3. The drilling relieves pressure within the bone and removes some of the dead tissue
  4. In some cases, bone graft or biologic material may be inserted to stimulate healing
  5. The channels allow new blood vessels to grow into the area
  6. The incisions are closed and the patient begins protected weight-bearing

Benefits of Core Decompression for Avascular Necrosis

  • Preserves the natural hip joint when successful
  • Prevents femoral head collapse in early-stage AVN
  • Minimally invasive procedure with small incisions
  • May avoid the need for joint replacement
  • Stimulates new blood vessel growth
  • Allows for potential future procedures if needed

Recovery After Core Decompression

Recovery Timeline: 3-6 Months for Bone Healing

Recovery from core decompression requires careful protection of the healing bone to prevent collapse. Patients typically use crutches for 6-12 weeks with protected weight-bearing.

Phase 1 (Weeks 1-6): Strict protected weight-bearing with crutches, gentle range of motion exercises, and avoidance of high-impact activities. The bone needs time to heal and revascularize.

Phase 2 (Weeks 6-12): Gradual progression to partial weight-bearing, continued protection of the healing bone, and initiation of low-impact exercises.

Phase 3 (Months 3-6): Progressive return to full weight-bearing as healing is confirmed on imaging, continued low-impact exercise, and gradual return to activities.

Long-term: Regular monitoring with imaging to assess healing. If successful, patients can return to normal activities. If collapse occurs despite treatment, joint replacement may be necessary.

Frequently Asked Questions

What is core decompression for avascular necrosis?

Core decompression is a joint-preserving surgery for early-stage avascular necrosis (AVN). The surgeon drills small holes into the femoral head to reduce pressure, stimulate new blood vessel growth, and slow bone death.

Who is a candidate for core decompression?

Ideal candidates have early-stage AVN (pre-collapse stages) detected on MRI with minimal symptoms. Success rates are highest when performed before femoral head collapse. Late-stage AVN with collapse requires hip replacement rather than decompression.

What is the success rate of core decompression?

Success varies by AVN stage. Early-stage (Ficat I-II) success rates are 60-85% in slowing progression. Late-stage or post-collapse cases have poor outcomes. Younger patients and those addressing underlying causes (stopping steroids/alcohol) have better results.

What is the recovery time for core decompression?

Patients use crutches with protected weight-bearing for 6-12 weeks to allow healing. Full recovery takes 3-6 months. Avoiding impact activities initially prevents femoral head collapse during healing. Serial X-rays monitor bone healing and potential progression.

What happens if core decompression fails?

If AVN progresses to femoral head collapse despite decompression, total hip replacement becomes necessary. Some patients may undergo vascularized bone grafting as a bridge procedure before eventual replacement if young.
