What is Perthes Disease?

Legg-Calvé-Perthes disease is a condition in which blood supply to the femoral head is disrupted, leading to avascular (non-infectious) necrosis. It most commonly affects children 3-12 years old (peak incidence 5-7 years), predominantly boys (4:1 ratio).

The disease progresses cyclically: necrosis → fragmentation → healing → remodeling. The natural course takes 2-5 years. The primary concern is deformity of the femoral head, which can lead to early osteoarthritis in adulthood.

Stages of disease (Waldenström classification):

  • I — Necrosis — disruption of blood supply, beginning of destruction. X-rays may appear normal
  • II — Fragmentation — femoral head breaks down, areas of lysis appear. The most critical period
  • III — Healing — new bone tissue growth, reossification
  • IV — Remodeling — final shaping of the head. Deformity (coxa plana, coxa magna) determines long-term prognosis

Facts about Perthes Disease

  • ICD-10: M91.1
  • Age: 3-12 years (peak 5-7)
  • Gender: boys 4 times more often
  • Bilateral: 10-15% of cases
  • Duration: 2-5 years
  • Risk: early hip osteoarthritis with deformity

Symptoms of Perthes Disease

Early signs

  • Limping (child limps without apparent cause)
  • Pain in the groin, thigh, or knee
  • Limited hip rotation and abduction
  • Fatigue with walking
  • Muscle spasm

Progression

  • Limb shortening
  • Atrophy of thigh and buttock muscles
  • Marked limitation of movement
  • Inability to run and jump
  • Positive Trendelenburg sign

Prognostic factors

  • Age of onset — before age 6 has better prognosis
  • Degree of involvement — Herring classification (A, B, C)
  • Preservation of shape — the less deformation, the better
  • Early treatment — the key to a good outcome

How MIBRAR® helps with Perthes Disease

MIBRAR® accelerates natural bone regeneration, improves blood supply to the necrosis area, and helps prevent deformation of the femoral head — the main long-term problem of Perthes Disease.

01

Stage Assessment

MRI of the hip joint is analyzed to determine the disease stage, extent of involvement (Herring classification), and prognosis. An individual treatment plan is developed.

02

Obtaining Concentrates

From blood — CGF with angiogenic factors (VEGF, PDGF) for restoration of blood supply. From adipose tissue — Lipogems® with stem cells to accelerate osteogenesis.

03

Injection into Necrosis Area

Under navigational control, concentrates are delivered directly into the femoral head — the area of disrupted blood supply. The procedure is minimally invasive and safe.

04

Accelerated Recovery

Stem cells and growth factors stimulate neovascularization and osteogenesis. This accelerates the recovery phase and promotes formation of a more spherical femoral head, reducing the risk of deformation and early osteoarthritis.

Scientific Basis of MIBRAR® for Perthes Disease

Traditional treatment of Perthes Disease involves observation, orthoses, activity restriction, and in severe cases — surgery (osteotomy). None of these methods accelerate bone regeneration. MIBRAR® fills this gap — delivering stem cells and growth factors directly to the necrosis area.

How MIBRAR® Affects Perthes Disease:

  1. Neovascularization — vascular growth factors (VEGF, PDGF, FGF) stimulate growth of new blood vessels in the ischemic area, restoring blood supply to the femoral head
  2. Osteogenesis — mesenchymal stem cells differentiate into osteoblasts and accelerate formation of new bone tissue in the recovery phase
  3. Anti-inflammatory effect — reduction of synovitis and edema typical of the active disease phase
  4. Preservation of shape — accelerated regeneration helps maintain a more spherical femoral head shape, reducing the risk of deformation (coxa plana)

Important: MIBRAR® is most effective in early stages and the fragmentation phase, when natural recovery begins. Each case is evaluated individually.

Advantages of MIBRAR® for Perthes Disease

  • Accelerated recovery — shortened disease duration
  • Deformation prevention — preservation of femoral head shape
  • Minimal invasiveness — micro-puncture
  • Without general anesthesia — local anesthesia
  • Osteoarthritis protection — long-term prognosis

Frequently Asked Questions about Perthes Disease Treatment

From what age can Perthes Disease be treated with the MIBRAR® method?
Each case is evaluated individually. MIBRAR® uses the patient's own cells (autologous concentrates), minimizing risks. Prof. Babayan will assess the MRI images and determine feasibility and optimal treatment timing.
Can MIBRAR® prevent femoral head deformation?
MIBRAR® accelerates bone tissue regeneration and improves blood supply, which promotes the formation of a more spherical femoral head. The earlier treatment is started and the smaller the volume of damage, the higher the chances of preventing significant deformity.
Does MIBRAR® replace traditional Perthes Disease treatment?
MIBRAR® can be applied as a complement to standard treatment (activity restriction, physiotherapy, orthoses) or as an alternative to surgical intervention in suitable cases. Regenerative concentrates accelerate the natural recovery process, which with standard treatment takes 2–5 years.
Does MIBRAR® treat the consequences of Perthes Disease in adults?
Yes. Adults with consequences of Perthes Disease (femoral head deformity, early Hip Osteoarthritis) are good candidates for MIBRAR®. Regenerative concentrates restore cartilage, reduce inflammation, and slow the progression of osteoarthritis, delaying or eliminating the need for joint replacement.
