A minimally invasive technique of core decompression and cancellous bone grafting of femoral head osteonecrosis

Abstract

Background: Osteonecrosis, or avascular necrosis (AVN), is a severe condition affecting the hip joints, particularly in younger and middle-aged individuals. Detecting it early and managing it effectively is crucial to prevent secondary osteoarthritis and potential hip replacement surgery. Core decompression and bone grafting are primary treatments in the initial stages, aiming to restore blood flow to the femoral head and prevent its deformation. However, traditional surgical methods involving extensive dissection may compromise blood supply to the femoral head. To counter this, we've developed an innovative minimally invasive technique for core decompression and bone grafting. This approach minimizes tissue disruption, reduces bleeding, shortens surgery time, ensures precise graft placement, facilitates graft impaction, and lowers the risk of graft failure. Implementing this technique allows us to effectively manage early AVN stages while also making the surgery more cost-effective.Our minimally invasive core decompression and bone grafting technique present significant advantages in treating early-stage AVN of the femoral head. By preserving vascularity in the affected area, we aim for successful outcomes and potentially steer clear of more invasive procedures such as total hip replacement surgery. Aim: To introduce a novel technique of minimally invasive core decompression and cancellous bone grafting for femoral head osteonecrosis. Methods: Clinical data from patients diagnosed with AVN and treated using the minimally invasive novel technique were retrospectively analyzed. Conclusion: This novel technique of core decompression and bone grafting is a simple, safe, and reliable joint-preserving surgical treatment for early-stage avascular necrosis. It avoids serious perioperative complications, utilizes an inexpensive adjuvant substance, and holds promise in preventing disease progression and minimizing the need for more invasive procedures like total hip arthroplasty.
