OBJECTIVE
To explore the recent clinical curative effect of Tantalum rod in treating the early avascular necrosis.
METHODS
From January 2008 to November 2008, the 25 patients (39 hips) with early avascular necrosis accepted tantalum rod placement and included 9 males (11 hips) and 16 females (28
OBJECTIVE
To study the effectiveness of avascular necrosis of the femoral head treated by lesions clearance,
METHODS
Between March 2008 and May 2010, 14 patients (16 compact bone grafting, and porous tantalum rod implantation. hips) with avascular necrosis of the femoral head were treated by lesions
Incorrect treatment for femur head necrosis can cause collapse of femoral head and tresult in severe harm for the patients (especially for the patient with middle-aged and young). The structure and mechanics characteristics of tantalum rod is similar to bone tissue, it higher strength and can adapt
Femoral head necrosis (FHN) is a progressive pathology due to the failure of blood supply to the proximal femoral epiphysis, with consequent necrosis of the sub-chondral bone and collapse of the articular cartilage and loss of congruity between the head and the acetabulum. Borrowing the biological
OBJECTIVE
To investigate a new method for the treatment adult early femur head necrosis in order to avoid further collapse and necrosis and improve the clinical symptoms.
METHODS
From January 2009 to June 2010, 10 hips of 9 patients, including 7 males and 2 females, aged from 29 to 63 years old
The aim of this study was to evaluate the effect of a porous tantalum rod implant for the treatment of early femoral head necrosis. From April 2007 to June 2009, a total of 35 femoral head necrosis patients (with 49 hips) were treated with core decompression in combination with the insertion of a
Avascular necrosis of the femoral head (ANFH) is a common ailment characterized by necrosis of bone trabecular and bone marrow. It's mainly caused by the destruction of the blood supply in the femoral head and high rate of morbidity and disability is involved. Many methods have been tried including
OBJECTIVE
The effective results shown in the porous systems of tantalum employed for the use of osseointegrates has been demonstrated by means of animal experimentation. However, there is a total lack of any research studies on the osseointegration of tantalum implants from retrieval of the same
Efficacy of osteointegration of tantalum porous systems has been demonstrated through animal experimentation. However, there is a lack of studies that evaluate osteointegration of implants retrieved after a period of implantation in humans. For this study, eight rod implants used for the treatment
Porous tantalum rod implantation is a novel surgical method that is used to treat avascular necrosis (AVN) of the femoral head (hip). In the present study, the results of core decompression and tantalum rod implantation were compared with non-surgical treatment for AVN, and the survivorship of the
Objective: To compare the clinical effects of marrow core decompression with bone grafting and marrow core decompression with porous tantalum rod implantation in treating avascular necrosis of non-traumatic femoral head.
OBJECTIVE
Femoral head necrosis (FHN) is a debilitating disease which seriously affects the patients' quality of life, especially the young. The porous tantalum rod has the advantages of high volumetric porosity, low modulus of elasticity, and excellent osteoinduction, with exceptional
Global avascular necrosis of the talus is a devastating complication that usually occurs as a result of a post-traumatic or metabolic etiology. When conservative options fail, tibiocalcaneal arthrodesis is generally indicated in conjunction with massive bone grafting to maintain the functional
Cobalt-chromium-molybdenum alloys with high carbon content (HC-CoCrMo) are widely used as materials for arthroprosthesis, in particular in metal-on-metal (MoM) hip joints. In spite of their good wear and corrosion resistance, production of metallic wear particles and metal ion release will occur on
