Wrist Avascular Necrosis (AVN) or Osteonecrosis

 AVN Treatment Options

 Tampa, Saint Petersburg and Clearwater, Fl

What is AVN?


Avascular Necrosis (AVN) is a condition in which the blood flow to a region of bone is disrupted and the bone then dies (necrosis).

There are many terms in the medical literature for AVN (synonyms).

Avascular Necrosisavn wrist


Ischemic Necrosis

Bone infarction

All these terms basically reflect the loss of blood flow (Avascular or ischemic), and the term bone or osteo with the word necrosis, which reflects bone death.


Wrist Bones

The most commonly affected bones in the wrist with AVN, are the carpal bones the lunate and scaphoid. The lunate is more commonly affected than the scaphoid.

Trauma is the predominate risk factor for the development of osteonecrosis in the wrist.


Risk Factors


Idiopathic (unknown)

Steroids (cortisone)

Alcohol excess


Disease states (Lupus, Sickle cell, Gaucher’s, Caisson’s)



X-rays, bone scan, and MRI show characteristic findings.

Pain and tenderness over affected bone.



Rest and immobilization in a cast is a mainstay of treatment. If bone and joint collapse occurs, typically surgery is recommended for a variety of procedures depending on the surgeon. Carpal resection, prosthetic joint replacement or even wrist fusion may be offered.

STEM CELL THERAPY  has been used successfully in many joints with ischemic necrosis. The premise is quite simply, the body tries and naturally heal AVN with stem cells. It is just a difficult task to accomplish with the loss blood supply (avascular)

and the bone death (necrosis). Assisting the body in the natural healing process is the aim of Regenerative Medicine. Platelet Rich Plasma (PRP) and Stem Cell Therapy use this principles to aid in repair and regeneration.

Athletes with AVN are in need of successful treatment to stay in their sport. Most other desire a functional wrist with quality of life.
