This is a systematic review and meta-analysis study.The purpose of this systematic review and meta-analysis study is to evaluate the outcomes of a tantalum fusion device in anterior cervical discectomy and fusion (ACDF) for the treatment of cervical Porous tantalum osteonecrosis implants have been used in femoral head necrosis for several years, while the clinical outcomes were mixed. As a joint-preserving surgery, early necrosis deterioration and conversion to total hip arthroplasy failed our expectation. We hence investigate an observational
OBJECTIVE
To study a modified porous tantalum technique for the treatment of osteonecrosis of the femoral head.
METHODS
The porous tantalum rod was combined with endoscopy, curettage, autologous bone grafting and use of bone marrow aspirates from iliac crest aspiration in 49 patients (58 hips) with
In 15 human subjects, the vasa deferentia were occluded by applying two tantalum clips on one side and by conventional vasectomy with silk ligatures on the other. After 2 weeks, the occluded segments were recovered for histopathologic examination of serial sections. Obstructing the seminal tract did
BACKGROUND
Modem indications for use of cemented or uncemented implants in revision hip arthroplasty are comparable. The use of bone cement provides predictable short term results, but the lack of osteointegration deteriorates its long term durability. Uncemented implants undergo osteointegration,
OBJECTIVE
The study presents the mid-term results in patients treated with circumferential, i.e., 360-degreee, fusion of the lumbar spine carried out by posterolateral instrumented spondylodesis and anterior intersomatic fusion using a tantalum implant for replacement of an intervertebral disc. The
Osteonecrosis of the femoral head is a progressive disease. Without operative intervention, it most often results in collapse and deterioration of the joint. Many joint-preserving surgeries have been implemented, but no uniform treatment exists. The authors report a modified technique of tantalum
To study the functional significance of transient coronary occlusion on systolic and diastolic left ventricular function relative to the anatomic site of occlusion, first-pass radionuclide angiography with a mobile multiwire gamma camera using tantalum-178 (dose activity less than or equal to 84
BACKGROUND
Palmaz stents, Strecker stents, and Wallstents, all used clinically, differ substantially in their physical characteristics, yet how differently the vascular wall reacts to them has not been demonstrated conclusively. We therefore undertook a side-by-side comparison.
RESULTS
One stent was
BACKGROUND
Anterior cervical discectomy and fusion with a porous tantalum cage is an accepted method to treat degenerated cervical discs, with good results, similar to those with autologous bone graft and plating at short- and mid-term follow-up. However, to date, long-term follow-up studies have
The body is unable to repair and regenerate large area bone defects. Moreover, the repair capacity of articular cartilage is very limited. There has long been a lack of effective treatments for osteochondral lesions. The engineered tissue with biphase synthetic for osteochondral repair In this paper, we report on the use of tantalum as adhesion layer for platinum electrodes used in high-temperature SAW devices based on langasite substrates (LGS). Tantalum exhibits a great adhesive strength and a very low mobility through the Pt film, ensuring a device lifetime at 900°C of about
Because interventional radiology (IVR) procedures are being performed with increasing frequency, patient X-ray exposure dose for X-ray fluoroscopic and radiographic procedures should not be ignored. In order to avoid excessive X-ray exposure, exposure dose rate limits are specified in the Japanese
In controlled experiments, the posterior facial veins in the rabbits neck (diameter 1.5-2.0 mm) were repaired, either by manual suture with 10-0 nylon or by the use of Nakayama's ring pin stapler. The so-called Nakayama "animal" rings, made from metal alloy, as well as the "human" rings, made from
Elongation and migration of ACL grafts will lead to a deterioration of the initial stability of ACL reconstructions. The graft migration has been sparsely investigated independently from the elongation of the graft-fixation complex. The hypothesis of this investigation was that cyclic tensile loads
