The use of a bovine collagen construct for reconstruction of full-thickness scalp defects in the elderly patient with cutaneous malignancy.

Full-thickness defects of the scalp following cancer resection are reconstructive challenges when bone is exposed. Local, regional, and/or free tissue transfer have all been described for reconstruction when the pericranium is exposed. We examined the surgical outcomes from 23 patients who underwent placement of bovine collagen constructs.

A true aneurysm of the profunda femoris artery: a case report and review of the English language literature.

A rare case of true aneurysm of the profunda femoris artery (PFA) is reported. Surgical management consisted of ligation of the aneurysm and decompression of the sac. Presentation, diagnosis, and treatment of true PFA aneurysms are discussed and the English language literature is comprehensively reviewed.

Unique rodent model of distraction osteogenesis of the mandible.

Despite the increasing use of distraction osteogenesis (DO) of the mandible, the molecular mechanisms regulating new bone formation during DO remain poorly understood. The purposes of this study were (1) to establish a unique rodent model of DO capable of outlining parameters for new bone formation at the distraction site and (2) to determine a critical-size defect to differentiate osteogenesis resulting from distraction from conventional fracture healing at the osteotomy site. Adult Sprague-Dawley rats were fitted successfully with this newly developed distraction device.
