Effect of platelet-rich plasma combined with demineralised bone matrix on bone healing in rabbit ulnar defects.

Introduction: This study evaluates the effect of autologous platelet-rich plasma (PRP) combined with xenogeneic demineralised bone matrix (DBM) on bone healing of critical-size ulnar defects (2-2.5 times the ulnar diameter) in New Zealand White rabbits.

Methods: Critical-size defects were created unilaterally in the ulna of 36 rabbits, while keeping the contralateral limb intact.

The Effect of Low Molecular Weight Heparins on Fracture Healing.

Venous Thromboembolism is a serious complication in the trauma patient. The most commonly studied and used anticoagulant treatment in prophylaxis of thrombosis is heparin. The prolonged use of unfractionated heparin has been connected with increased incidence of osteoporotic fractures.

Georges-Paul Dieulafoy (1839-1911) and the first description of "exulceratio simplex".

Professor Georges Dieulafoy is considered to be an outstanding clinician who played a leading role in medicine during the 19th century. He invented the well-known Dieulafoy aspirator, he described a triad for the diagnosis of acute appendicitis and he tried to bridge the gap between internal medicine and surgery. This article presents in details the first description of "exulceratio simplex" that bears his name.

Sexual dimorphism of the hip joint in Greeks.

The objective of the present study was to report our measurements of hip bones within the Greek population and review the possible implications of these differences in their health as well as in social life. For this purpose the remains of 100 male and 100 female pelvic and femoral bones were studied. The distance from the pubic tubercle to the anterior rim of the acetabulum, the acetabulum diameter between its rims, their ratio, the depth of the acetabulum, the diameter of the femoral head and the ratio between the femoral head and the diameter of the acetabulum were measured.
