BACKGROUND Retrieval studies have suggested that the cause of femoral implant failure after metal-on-metal hip resurfacing is multifactorial. Both varus positioning of the femoral component and notching of the superior part of the femoral neck have been associated with femoral component failure. The hypotheses of this study were that placement of a femoral resurfacing component alters femoral n...

OBJECTIVE A review is made of the publications on bone regeneration using particulate grafts, with an evaluation of the success of implants placed in such regenerated areas. MATERIAL AND METHOD A Medline search using different key words was made of the articles published between 1999-2009 involving at least two patients subjected to grafting with autologous, homologous or xenogenic bone, non-...

Some patients with epilepsy not controlled by medication will benefit from surgical removal of the seizure focus in the brain, if the seizure focus can be identified. The seizure focus has to be localized in one hemisphere only. This is referred to as refractory complex partial epilepsy. The problem is that identification of the seizure focus is not easily accomplished. One way to identify the ...

There continues to be considerable interest in P and K fertilizer placement among cash grain producers for several reasons. Growers have faced low commodity prices for several years and are interested in certain placement methods that may enhance the efficiency of nutrient use and therefore reduce their input costs. This issue seems be more important in high residue management systems where bro...

Using a locomotor conditioning preparation, we examined whether manipulating time between exposure to distinct environmental cues and nicotine administration affected conditioned responding. Rats that received nicotine (0.42 mg/kg base) immediately before placement in an environment for 30 min on eight separate occasions displayed hyperactivity relative to controls in a subsequent injection/dru...

BACKGROUND Patients with resorbed edentulous alveolar ridges in the posterior maxilla often require lateral window sinus augmentation procedures prior to implant placement. Lateral window sinus augmentation procedures can produce incomplete bone augmentation as consequence of surgical and healing complications producing unusual and complex sinus anatomy. Although incomplete bone formation after...

PURPOSE We describe surgical outcomes in a single-surgeon, consecutive series of patients who received scleral buckle placement for primary retinal detachment using a modified external needle drainage technique. METHODS Eighty-two eyes of 80 patients with primary retinal detachment underwent scleral buckle placement with modified external needle drainage. Preoperative, postoperative, and surg...

A technique is described for accomplishing both localized sinus augmentation and guided bone regeneration at the time of maxillary molar extraction. One hundred nine sites were treated in 92 patients. Of these, 102 procedures (94.0%) were successful and 7 (6.0%) were partially successful. Success was defined as the ability to ideally position an implant at least 10 mm in length and 4.8 mm in wi...

Acute iatrogenic arterial dissection is a known complication of endovascular techniques and can be treated with prolonged ballooning, stent placement, or balloon fenestration. Treatment of common femoral artery (CFA) dissection needs special attention because of the potential compromise of either the deep or superficial femoral artery origin and the enhanced mechanical stress to arteries in the...
