[Predictive factors of perioperative morbidity in revision total hip arthroplasty].
The awareness and prevention of perioperative morbidity are essential in revision total hip arthroplasty [THA]. Therefore, it was the purpose of this study to assess the rate of perioperative complications following revision THA in order to evaluate the impact of patient- and procedure-related variables. ⋯ Revision status with a three-fold increase in patients with multiple revisions as well as operation duration with a 1 % increase per min starting from the mean operation time significantly influence the perioperative morbidity. Patients with a first revision, furthermore, seem to be at greater risk for an adverse event perioperatively if their implant is fully cemented. These findings should be taken into account prior to initiating surgery.

[A prospective two-year follow-up of thoracic and lumbar osteolytic vertebral fractures caused by multiple myeloma treated with balloon kyphoplasty].
Balloon kyphoplasty is a minimally invasive procedure for the stabilization of osteoporotic and osteolytic vertebral fractures. The purpose of this prospective study was to evaluate this operative procedure in the treatment of osteolytic vertebral fractures with regard to the reduction of pain and functional improvement of the patients and further to evaluate the restoration of vertebral height postoperatively. ⋯ In the treatment of osteolytic vertebral fractures balloon kyphoplasty led to a quick and sustained reduction of pain and as well as a functional improvement for the patients. A restoration of the vertebral height and reduction of the kyphotic angle was especially attributable to the balloon technique. The balloon kyphoplasty was able to stabilize the fractured vertebrae in the long-term and was able to prevent an increase of kyphotic deformity. Balloon kyphoplasty is an outstanding alternative in comparison to the established therapeutic concepts in the treatment of osteolytic vertebral fractures.

Comparative Study[Primary stability of cementless implanted hip stems made of titanium alloy with metaphyseal fixation. A prospective clinical Roentgen-Stereometry-Analysis (RSA) study].
Under early mobilisation and full weightbearing the primary stability of two different cementless hip stems should be examined by using Roentgen Stereometric Analysis (RSA). ⋯ Both cementless implanted titanium hip stems showed a sufficient primary and midterm stability with excellent clinical results. The measured migrations do not differ from those given in literature for cemented stems.

Comparative Study Controlled Clinical Trial[Comparative analysis of patient-centered outcome of total hip and knee arthroplasty].
The aim of the present study was a comparative investigation of the functional improvement reported by patients suffering from primary osteoarthritis of the knee or hip undergoing total joint replacement and assessed at 3 months. ⋯ We conclude that patients with hip replacement show more improvement 3 months after the surgery than patients with knee replacement. Furthermore, it was seen that patients who were more disabled before surgery achieved more improvement than the less-disabled patients. However, they did not achieve the level of the less disabled patients. Thus, the recommendation that total joint replacement should be performed as late as possible should be reviewed.

Randomized Controlled Trial[Postoperative autologous transfusion from blood drainage after total hip joint arthroplasty--how much value is really there?].
Are autologous blood transfusions sufficient or do we need the transfusion of unwashed or washed wound drainage blood in total hip arthroplasty? ⋯ We do not recommend the transfusion of wound drainage.
