What are the treatment options for avascular necrosis of the femoral head?

Question

Hello doctor,

My 6-year-old daughter has sickle cell disease and has recently been diagnosed with avascular necrosis of the femoral head. She experiences moderate pain when weight is applied to her leg. She has followed the recommended two-month bed rest. There is noticeable muscle atrophy in her right leg due to disuse, and there is also a leg length discrepancy. She walks with a limp and exhibits some stiffness in her hip. I have been informed that she is considered too young for surgery. Can physiotherapy be beneficial, and what are her available treatment options?

Hello,

Welcome to icliniq.com.

I read your query and understood your concern. Based on the information you provided, it seems to be avascular necrosis (AVN) of the femoral head, where blood flow to the bone is compromised. The treatment options can vary depending on the severity of the condition, the age of the patient, and other factors. While surgery may not be recommended for a 6-year-old, other treatment options and supportive measures can be considered. Physiotherapy can play a role in managing symptoms and promoting functional improvement. I suggest you following potential treatment options that you might consider:

Physiotherapy: Physiotherapy can help improve muscle strength, joint mobility, and overall function. A physiotherapist can design a tailored exercise program to address muscle atrophy, improve gait mechanics, and alleviate stiffness in the hip. They may also use modalities such as heat or cold therapy, electrical stimulation, or ultrasound to provide pain relief and promote healing.
Pain management: Medications such as nonsteroidal anti-inflammatory drugs (NSAIDs) or analgesics may be prescribed to help manage pain and discomfort.
Assistive devices: Depending on the extent of the leg length discrepancy and the associated gait abnormalities, your daughter may benefit from using assistive devices such as crutches or orthotic devices to support her mobility and relieve pressure on the affected hip joint.
Regular follow-up and monitoring: Close monitoring of the condition through regular check-ups and imaging studies can help assess the progression of AVN and determine if any changes in treatment approach are necessary.

I suggest you consult specialists and discuss with your daughter's healthcare team, including her pediatrician, orthopedic specialist, and physiotherapist. They will be able to provide you with specific guidance based on her individual condition and needs. Physiotherapy can play a significant role in addressing muscle atrophy and leg length discrepancy associated with avascular necrosis (AVN) of the femoral head. Here are some ways in which physiotherapy can help:

Muscle strengthening exercises: A physiotherapist can design a targeted exercise program to help strengthen the muscles that have experienced atrophy due to disuse. These exercises may include activities such as resisted movements, weight-bearing exercises, and functional movements that specifically target the affected muscles. Strengthening the muscles can help improve their size, strength, and overall function.
Range of motion exercises: Physiotherapy can involve specific exercises to improve joint mobility and reduce stiffness in the hip. These exercises may include passive or active range of motion exercises, stretching techniques, and joint mobilization techniques. Improving joint mobility can help alleviate stiffness, improve gait mechanics, and enhance overall functional movement.
Gait training: A physiotherapist can analyze your daughter's gait pattern and identify any abnormalities or compensatory movements caused by the leg length discrepancy or hip stiffness. They can then provide gait training exercises and techniques to promote a more symmetrical and efficient walking pattern. This may include exercises to address any muscle imbalances, improve weight distribution, and enhance overall walking mechanics.
Functional training: Physiotherapy can focus on functional training to help your daughter regain her ability to perform daily activities with greater ease and efficiency. This may involve exercises that simulate real-life movements and tasks, such as climbing stairs, getting up from a chair, or walking on uneven surfaces. Functional training can help improve overall functional capacity and independence.
Orthotic intervention: In some cases, a physiotherapist may recommend the use of orthotic devices, such as heel lifts or shoe inserts, to address the leg length discrepancy and provide better alignment and support during walking and weight-bearing activities. These devices can help reduce strain on the affected hip joint and improve overall gait mechanics.

I hope this has helped you. Kindly follow up if you have more doubts.

Thank you.
