Abstract
OBJECTIVES The purpose of this study was to examine the effects of the use of a vapocoolant blend of pentafluoropropane and tetrafluoroethane (Gebauer's Spray and Stretch) on hip flexion stretching. METHODS Thirty volunteers were randomly assigned to spray and stretch treatment and stretch only control groups. Each group was assessed pre- and posttest on passive and active hip flexion range of motion (ROM). RESULTS Findings indicated greater posttest hip flexion gains for the spray and stretch group over the stretch only group for both active and passive ROM. Additionally, females achieved greater pre- and posttest differences on active ROM compared to males. CONCLUSIONS Study findings suggest that spray and stretch techniques can be an effective treatment in increasing hip flexion ROM.

Abstract
Ninety patients (96 hips) scheduled for THA were stratified to fixation of the acetabular component in three main groups of about equal size. Fluoride cement, porous coated press-fit cup with ceramic coating or Palacos cum Gentamicin cement were used. All patients received Spectron EF stem. The migration of the cups and the femoral head penetration into the socket were measured with radiostereometric analysis. At 2 years the choice of fixation did not influence the migration or rotation of the cup. Patients with compromised bone quality showed increased three-dimensional (3D or total) migration. Proximal and 3D penetration rates were increased in cemented compared with the uncemented cups (p<0.001), which probably not could be related to the choice of fixation. Appearance of radiolucent lines was almost equal in the two cemented groups. Uncemented cups had less radiolucent lines at 2 years. Fluoride containing cement or uncemented fixation did not improve the early postoperative stability of the socket.

Abstract
BACKGROUND Tape blisters after hip surgery can be a source of postoperative morbidity and can increase patient discomfort. The purpose of this prospective study was to compare two different types of tape to determine whether the type of tape influences the rate of blister formation. METHODS Ninety-nine patients (100 hips) were enrolled in the study. Patients were randomized into one of two treatment groups: one treated with a nonstretchable silk tape and one treated with a perforated, stretchable cloth tape. After surgery, the assigned tape was applied over the postoperative dressing with care not to produce skin tension. At the first dressing change, the presence or absence of blisters was recorded as were the number, size, location, and type of any blisters. The presence or absence of tape blisters was recorded at the time of each subsequent dressing change. RESULTS A tape blister developed on twenty-five hips in twenty-five patients. The risk of a blister developing was 41% (twenty of forty-nine patients) when the nonstretchable silk tape was used and 10% (five of fifty patients) when the perforated cloth tape was used (relative risk = 4.08, 95% confidence interval = 1.53 to 10.87, p = 0.005). We found no association between formation of tape blisters and the age or gender of the patient, number of medical comorbidities, smoking history, results of nutritional assessment, or type of surgery. CONCLUSIONS The prevalence of tape blisters was significantly lower when perforated cloth tape was used than it was when nonstretchable silk tape was used.

Abstract
QUESTION The conically clamping inlay of solid metal for the Hofer-Imhof threaded socket makes possible the use of a metal-metal-bearing by completely dispensing with polyethylen but keeping the four-elements-construction of THR. In order to perceive long-term problems and complications patients of our hospital who took part in a closed multi-center-study which was established prospectively were checked again. METHOD Clinical and X-ray examination of 27 patients after 19 months on an average (12-23 months). RESULTS Harris-score increased from 38 points before the operation to 89 points three months after the operation and 91 points in the present check-up. Three months after the operation 22 patients were free of pain, at present only 12. X-Rays did not show any signs of loosening within the prostheses. But increasing ectopic ossifications of Brooker were found: ten times Class I, once Class II and six times Class III. CONCLUSION Using equal form of after treatment the increasing break out of pain as well as the growing symptom of ectopic ossifications in the hip area after the implantation of the Hofer-Imhof threaded socket with solid metal inlay is presumably caused by the use of the metal-metal-bearing as well as by the direct lining of the Co-Cr-inlay in the titan-socket and by possible changes in corrosion.
