Common Symptoms and Functional Limitations of AVN Hip

AVN of the hip often begins with mild, aching pain in the groin, buttock, or thigh. This discomfort may worsen with walking or standing and can gradually become more persistent. As the disease progresses, patients may notice stiffness, reduced hip movement, and difficulty performing daily activities like climbing stairs or sitting cross-legged.

In advanced stages, the hip joint may lose its normal shape, leading to a limp and severe pain even at rest. Functional limitations can include trouble getting up from a chair, decreased walking distance, and reliance on support for balance. Early recognition of these symptoms is crucial for timely intervention and better outcomes[c2].

  • Groin or thigh pain, especially with activity
  • Stiffness and reduced hip movement
  • Limping or difficulty walking
  • Pain at rest in advanced cases
  • Difficulty with daily tasks (e.g., stairs, sitting)

Diagnosis and Candidacy Assessment for AVN Hip Treatment

Key Imaging Tests Used to Confirm AVN Hip Diagnosis

Imaging plays a central role in diagnosing AVN of the hip. X-rays are usually the first step and can reveal changes in bone structure in moderate to advanced cases. However, early AVN may not be visible on X-ray, so MRI scans are considered the gold standard for detecting early bone changes and assessing the extent of damage[c3]. CT scans may also be used to evaluate joint collapse or plan surgery.

These imaging tests help doctors determine the stage of AVN, which guides treatment decisions. MRI is especially useful for identifying candidates for hip-preserving procedures before the joint surface collapses. Accurate imaging ensures the most appropriate and timely intervention is chosen.

How Doctors Assess Eligibility for AVN Hip Procedures

Doctors evaluate several factors to decide if a patient is suitable for hip-preserving surgery or requires joint replacement. Key considerations include the stage of AVN, age, activity level, and overall health. Early-stage AVN with preserved joint shape may be managed with core decompression or bone grafting, while advanced collapse often requires hip replacement.

Other factors, such as the presence of other medical conditions and the patient’s expectations, are also considered. A thorough assessment ensures that the chosen procedure offers the best chance for pain relief and improved mobility.

Role of Blood Tests and Fitness Evaluation Before Surgery

Before any surgical intervention, blood tests are performed to check for anemia, infection, and overall organ function. These tests help identify risks that could affect healing or increase complications. Screening for underlying causes of AVN, such as steroid use or blood disorders, may also be included.

A fitness evaluation, including cardiac and respiratory assessment, is essential to ensure the patient can safely undergo anesthesia and surgery. Addressing any medical issues before the procedure helps reduce the risk of complications and supports a smoother recovery process.

  • X-ray: Initial screening for bone changes
  • MRI: Detects early AVN and guides treatment
  • CT scan: Assesses joint collapse or surgical planning
  • Blood tests: Rule out infection and assess fitness
  • Fitness check: Ensures safe anesthesia and recovery

Non-Surgical Treatment Options for AVN Hip

Medications and Physical Therapy for Early AVN Hip

For early-stage avascular necrosis (AVN) of the hip, doctors may recommend medications such as non-steroidal anti-inflammatory drugs (NSAIDs) to reduce pain and swelling. Bisphosphonates or statins can sometimes be prescribed to slow bone damage, though their benefits are still being studied[c4]. Physical therapy is important for maintaining joint mobility and muscle strength, which can help delay progression of symptoms.

Supervised exercises focus on gentle range-of-motion and strengthening routines. These therapies do not reverse AVN but may improve daily function and reduce discomfort. Patients should follow their physiotherapist’s advice closely to avoid overloading the hip joint.

  • NSAIDs for pain relief
  • Bisphosphonates may slow bone loss
  • Supervised physiotherapy is key
  • Medications do not cure AVN

Lifestyle Modifications and Activity Restrictions

Lifestyle changes are essential in managing early AVN of the hip. Patients are usually advised to limit weight-bearing activities, such as running or jumping, to reduce stress on the affected joint. Using a walking aid like a cane can help offload pressure and slow joint deterioration.

Other recommendations include avoiding alcohol and tobacco, as these can worsen blood supply to the hip bone. Maintaining a healthy weight and following a balanced diet may also support bone health. These measures are most effective when started early and combined with medical management.

  • Limit high-impact activities
  • Use walking aids if needed
  • Avoid alcohol and smoking
  • Maintain healthy body weight

Surgical Procedures for AVN Hip in India

Core Decompression and Bone Grafting Techniques

Core decompression is a surgical procedure where a small channel is drilled into the affected hip bone to relieve pressure and improve blood flow. This technique is often used in the early stages of AVN to help preserve the natural joint. Sometimes, bone grafting is added to support bone healing and provide structural stability[c5].

Bone grafts may be taken from the patient’s own body or from a donor. The goal is to encourage new bone growth and delay or prevent the need for hip replacement. Recovery can take several weeks, and patients may need to use crutches during the healing period.

  • Relieves bone pressure
  • Improves blood supply
  • May delay joint replacement

Total Hip Replacement: Indications and Procedure Steps

Total hip replacement is recommended when AVN has caused significant joint damage and pain that limits daily activities. The procedure involves removing the damaged bone and cartilage and replacing them with artificial components made of metal, ceramic, or plastic[c6].

The surgery is performed under anesthesia and typically takes 1–2 hours. Patients usually begin walking with support within a day or two after surgery. Most people experience a major reduction in pain and improved mobility after recovery.
