Transvaginal emergence of a broken cup marker ring 21 years after total hip arthroplasty.

Broken cups, wires, and cable systems have the potential to cause complications, and they can migrate into joints, abdominal and thoracic organs. We describe a case of migration and transvaginal emergence of a marker wire from a polyethylene cup.

The effect of stress-reducing, low-dose ethanol infusion on frequency of bleeding complications in long-term alcoholic patients undergoing major surgery.

Perioperative low-dose ethanol infusion is a feasible option for stress reduction and prophylaxis of alcoholism-associated complications. Because alcohol has inhibitory effects on hemostasis, our study focused on the effect of perioperative low-dose ethanol infusion on bleeding complications, defined as transfused blood units and reoperations, in alcoholic patients undergoing major surgery. We included 44 long-term alcoholic patients scheduled for tumor resection of the aerodigestive and gastrointestinal tract.

A prospective, randomized study of computer-assisted and conventional total knee arthroplasty. Three-dimensional evaluation of implant alignment and rotation.

Background: Despite the use of modern instruments in total knee arthroplasty, component malalignment remains a problem. Whether a computer-assisted implantation technique can improve the accuracy of the spatial positioning of an implant is a matter of debate. The objective of this study was to determine whether computer-assisted total knee arthroplasty is superior to the conventional surgical method with regard to the precision of implant positioning.

Autologous bone marrow-derived cells enhance muscle strength following skeletal muscle crush injury in rats.

Insufficient post-traumatic skeletal muscle regeneration with consecutive functional deficiency continues to be a serious problem in orthopedic and trauma surgery. Transplantation of autologous muscle precursor cells has shown encouraging results in muscle trauma treatment but is associated with significant donor site morbidity. In contrast to this, bone marrow-derived (BMD) cells can be obtained without any functional deficit by puncture.
