Bioabsorbable implants.

Absorbable implants have become the hottest implant material, overtaking titanium as the future. Absorbable devices have moved beyond orthopedics and maxillofacial surgery to spine, vascular, plastics and general surgery. This chapter outlines the experiences of many specialties.

Acquired fibrokeratoma of the heel.

Acquired fibrokeratomas traditionally have been classified by both appearance and anatomical location. They are benign, solitary lesions that characteristically involve the digits of the hands and feet. The authors present a case with unusual involvement of the plantar surface of the heel.

Diagnosis of abdominal lesions. The use of intravenous aortography, nephrotomography and retrograde aortography.

New and safe methods of investigating the kidney by x-ray visualization of its circulation are now available. This can be done either by injecting large amounts of contrast material through a vein and then taking multiple x-ray exposures of the kidneys, or by injecting the contrast material backward into the aorta to the level of the renal arteries. Another method of x-ray examination now available is taking body section films of the kidneys when the contrast medium is in the kidney substance.
