Core decompression is one of the more popular procedures for the treatment of early stages of avascular necrosis (AVN) of the femoral head. However, the controversy regarding its safety and effectiveness continues. In an attempt to clarify the situation, we are reporting on a large series of cases performed by a single surgeon with long-term follow-up. This is a prospective study in which resul...

Background: Hip joint preserving procedures delay the progression of femoral head osteonecrosis. Non-vascularised autologous bone grafts have been used to fill necrotic area and prevent collapse head. Harvesting use neck graft, minimizing donor site complications favoring regeneration after core decompression. Methods: 17 patients in early stage osteonecrosis were operated, 12 males 5 females w...

The thermal conductivities of mantle and core materials have a major impact on planetary evolution, but their experimental determination requires precise knowledge sample thickness at high pressure. Despite its importance, in most diamond anvil cell (DAC) experiments is not measured inferred from equations state, assuming isotropic contraction upon compression or expansion decompression. Here w...

A broken guide wire while operating on hip is one of every surgeon's most dreaded nightmares. We report here a method which was used successfully to retrieve a broken guide wire from a patient who was being operated for core decompression and fibular grafting for avascular necrosis of the femoral head.

Although core decompression is one of the more popular procedures for treating avascular necrosis, considerable controversy exists concerning its safety and effectiveness. The current authors review the results of a prospective study of 406 hips in 285 patients treated by one surgeon with core decompression and bone grafting. Patients were followed up for 2 to 14 years. The outcome was determin...

Osteonecrosis of the femoral head is an intractable disease often occurring in patients aged 30-40 years that can cause femoral head collapse, pain, and gait disturbance. Background factors, including corticosteroid use, alcohol intake, and idiopathic causes, have been indicated. It is estimated that 70-80 % of osteonecrosis patients experience femoral head collapse, for which total hip arthrop...

BACKGROUND This study analyzed the long-term outcomes of extracorporeal shockwave therapy (ESWT) and core decompression for early osteonecrosis of the femoral head (ONFH) with 8- to 9-year follow-up. METHODS The study cohort consisted of 48 patients with 57 hips including 23 patients with 29 hips in the ESWT group and 25 patients with 28 hips in the surgical group. Patients in ESWT group rece...

BACKGROUND Osteonecrosis of the femoral head can lead to destruction of the hip joint and disabling arthritis in young adults, if left untreated. Among the salvage procedures, core decompression combined with bone graft substitutes is a viable option for joint preservation. The purpose of this study was to review the outcomes of using synthetic bone graft substitute (calcium sulfate and calcium...
