A. Definition of AVASCULAR NECROSIS (AVN)
Avascular necrosis (AVN) is a condition in which the blood supply of the bone tissue is disrupted and causes bone cell death.
This can happen in any bone, but it most commonly occurs in the hip joint.
B. Cause of AVN
Common causes of AVASCULAR NECROSIS (AVN) include trauma, long-term use of corticosteroids, and excessive alcohol consumption.
Symptoms of AVASCULAR NECROSIS (AVN) include joint pain, stiffness, and limited range of motion.
II. Stages of Avascular Necrosis
The “Ficat and arlet” classification system divides AVN into four stages based on the extent of bone damage seen in imaging studies such as X-rays and MRI scans.
- In stage 1, the bone is still healthy but may begin to show signs of damage.
- In stage 2, the bone begins to show signs of damage, but there are no fractures.
- In stage 3, there is a fracture or collapse of the bone.
- In stage 4, there is a complete collapse of the bone.
III. Treatment option for AVASCULAR NECROSIS (AVN)
A. Surgical Treatment, and
B. Conservative Treatment
A. Surgical Treatment
In the surgical treatment of AVN- Joint replacement surgery is most common. While surgery can be effective in treating AVN, there are some drawbacks and potential complications associated with this procedure. Some of the drawbacks of surgery in AVN include:
- Risks of anesthesia: Surgery requires the use of anesthesia, which carries risks such as allergic reactions, breathing problems, and even death in rare cases.
- Risk of infection: There is a risk of infection associated with any surgical procedure, including surgery for AVN.
- Bleeding: Surgery for AVN can lead to bleeding, which may require blood transfusions in some cases.
- Pain and discomfort: Surgery can cause pain and discomfort, which may require medication and a period of recovery time.
- Age Factor: The age factor is very important to decide whether to go for surgery or not, since the implant life is 15-20 years. In the case of a young patient, revision (surgery) is needed and it will be very complicated to operate on the same hip again.
B. Conservative Treatment for AVASCULAR NECROSIS (AVN)
In conservative treatment, it can be
- Core decompression, and
A. Core Decompression
In a conservative treatment known as core decompression, the inner layer of the bone is removed to release pressure and enhance blood flow to the injured area.
Some of the drawbacks of core decompression in AVN include:
- Limited effectiveness: Core decompression may not be effective in treating more advanced stages of AVN, where there is significant bone damage and collapse.
- Risk of fracture: Core decompression can weaken the bone, which may increase the risk of fracture in some patients.
- Limited long-term success: While core decompression can provide short-term relief from pain and slow down the progression of AVN, the long-term success of the procedure is limited. Some patients may still require joint replacement surgery in the future.
- Cost: Core decompression can be expensive, and the cost may not be covered by insurance in all cases.
B. Physiotherapy Treatment
AVASCULAR NECROSIS (AVN) Specific Physiotherapy Treatment such as shockwave therapy, class 4 LASER, TRF (Targeted Radio Frequency) Therapy/ Tecar Therapy, and Super Inductive System SIS are non-surgical treatment options for AVASCULAR NECROSIS (AVN). These techniques help to increase blood flow to the affected area and promote healing.
1. Shockwave Therapy
Shockwave therapy involves the use of high-energy sound waves to stimulate healing and reduce pain. This technique is often used for chronic pain conditions such as AVASCULAR NECROSIS (AVN).
2. Class 4 LASER
Class 4 LASER is a non-invasive treatment that uses light energy to stimulate healing and reduce pain. This technique is often used for soft tissue injuries and chronic pain conditions.
3.TRF (Targeted Radiofrequency) Therapy/ TECAR Therapy
TRF (Targeted Radiofrequency) Therapy/ TECAR Therapy is a non-invasive treatment that uses radiofrequency energy to stimulate healing and reduce pain. This technique is often used for musculoskeletal injuries and chronic pain conditions.
4. Super Inductive System (SIS)
Super Inductive System SIS is a non-invasive treatment that uses electromagnetic energy to stimulate healing and reduce pain. This technique is often used for chronic pain conditions such as AVASCULAR NECROSIS (AVN).
In conclusion, AVASCULAR NECROSIS (AVN) is a serious condition that can cause significant pain and limited mobility. However, Advanced Physiotherapy treatment for AVN (Avascular necrosis) will be a great health rather than surgery. By working with the physiotherapist at the Elite Physiotherapy and sports injury centre and exploring these treatment options, you can take the first step toward overcoming AVASCULAR NECROSIS (AVN) and regaining your quality of life.
