Immunohistochemical study of angiogenesis after local administration of platelet-rich plasma in a patellar tendon defect.

A full thickness defect was made in the central portion of the patellar tendon of 48 New Zealand white rabbits. Platelet-rich plasma (PRP) gel was then applied and filled the tendon defect. The same procedure was performed in the control group, without the application of PRP.

Comparative study of 5 different membranes for guided bone regeneration of rabbit mandibular defects beyond critical size.

Background: Although several studies have examined use of collagen membranes in guided bone regeneration (GBR), none has examined the use of human fascia temporalis as a bioabsorbable barrier. The majority of studies related to GBR have examined critical size defects. We sought to assess the human fascia temporalis and other well-documented membranes applied for GBR in mandibular osseous defects beyond critical size.

External fixation of intertrochanteric fractures in elderly high-risk patients.

This study concerns 56 elderly high-risk patients with an intertrochanteric fracture of the femur, who were treated with the Citieffe/Ch-N external fixator between November 2002 and February 2004. A short intraoperative time (37 minutes), no need for peroperative blood transfusion, fast mobilisation and a short hospitalisation (average 6 days, thus reducing the total cost) were noted. Union was obtained in all patients after 6 months.
