Augmented Reality Navigation-Guided Core Decompression for Osteonecrosis of Femoral Head

Core decompression with bone marrow injection for the treatment of femoral head osteonecrosis
Background:
Core decompression has been recommended in treatment of non-traumatic femoral head necrosis in early stage. Injection with patient's own bone marrow from the iliac crest might promote bone formation in the femoral head.
Objective:
To evaluate the result of patients treated by this technique.
Material And Method:
Retrospective review of a series cases by the medical records and radiographic pictures.
Results:
There were 34 procedures from 32 patients. Mean follow-up time was 24.6 months in stage 2 and 27.8 months in stage 3. Radiographic progression was observed in 76% and 69% of stage 2 and 3. Twenty one percent of stage 2 hips underwent other surgeries when 46% of stage 3 did at last follow-up. Pain relief was observed in all cases after the surgery.
Conclusion:
The proposed technique yielded only fair results. Probably due to most patients had steroid related pathology.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
