Use of preoperative embolization prior to Transplant nephrectomy.

Introduction: After a failed transplant, management of a non-functional graft with pain or recurrent infections can be challenging. Transplant nephrectomy (TN) can be a morbid procedure with the potential for significant blood loss. Embolization of the renal artery alone has been proposed as a method of reducing complications from an in vivo failed kidney transplant.

Testosterone and the prostate: implications for the treatment of hypogonadal men.

Late-onset hypogonadism (LOH) and testosterone replacement therapy (TRT) are subjects of much recent research. Because aging men are at risk for benign prostatic hyperplasia (BPH) and prostate cancer, elucidating the relationship between testosterone and these diseases is crucial to ensure its safe administration. It is known that testosterone supplementation may worsen active prostate cancer and that its blockade or removal slows the disease's progression.

Ontogenetic structural and material variations in ovine calcanei: a model for interpreting bone adaptation.

Experimental models are needed for resolving relative influences of genetic, epigenetic, and nonheritable functionally induced (extragenetic) factors in the emergence of developmental adaptations in limb bones of larger mammals. We examined regional/ontogenetic morphologic variations in sheep calcanei, which exhibit marked heterogeneity in structural and material organization by skeletal maturity. Cross-sections and lateral radiographs of an ontogenetic series of domesticated sheep calcanei (fetal to adult) were examined for variations in biomechanically important structural (cortical thickness and trabecular architecture) and material (percent ash and predominant collagen fiber orientation) characteristics.

The orthopedist as clinical densitometrist: cost- and time-effectiveness.

We tested the hypothesis that an orthopedic surgeon and his or her staff can efficiently and economically provide a bone densitometry service. This hypothesis reflects a philosophy that orthopedists should take a more active role in identifying patients at risk for osteoporosis. We evaluated the cost- and time-effectiveness of an orthopedic surgeon and his medical assistant in completing reports and related correspondence for dual-energy x-ray absorptiometry scans conducted in an orthopedic subspecialty clinic.

Knowledge and opinions of orthopaedic surgeons concerning medical evaluation and treatment of patients with osteoporotic fracture.

Background: With the exponential increase in osteoporotic fractures, orthopaedic surgeons are in a logical position to become more involved in the medical treatment of this disease. However, it has been hypothesized that surgeons may not be inclined to initiate such treatment if they do not view medical interventions as an extension of their surgical opportunities. The objective of this study was to determine the knowledge and opinions of orthopaedic surgeons with regard to their opportunities for initiating medical treatment of patients with an osteoporotic fracture.
