Effectiveness of fibrin sealant after cementless total hip replacement: a double-blind randomized controlled trial.

Unlabelled: Fibrinogen-based sealants have been used to improve hemostasis after total hip replacement (THR) with conflicting results. We therefore conducted a double-blind randomized controlled trial to determine whether the commercially available fibrin sealant Quixil is effective in reducing the volume of red blood cell transfusions, postoperative blood loss and postoperative hemoglobin drop. Patients with coxarthrosis scheduled for primary cementless THR, were enrolled in a single hospital setting and randomized to either a fibrin sealant group (n=35) or a negative control group (n=35).

Cementless Metasul metal-on-metal total hip arthroplasties at 13 years.

Second-generation metal-on-metal bearings have been used since the late 1980s as alternative bearings to eliminate aseptic loosening due to polyethylene wear. The aim of the present study was to evaluate the long-term results of a series of Metasul (Zimmer GmbH, Winterthur, Switzerland) metal-on-metal total hip arthroplasty (THA). One hundred forty-nine cementless THAs with a 28-mm Metasul articulation were performed in 111 consecutive patients.

[Italian consensus on EULAR recommendations 2005 for the management of hip osteoarthritis].

The recommendations for the management of osteoarthritis (OA) of the hip were proposed by EULAR in 2005. Among the most important objectives of the expert charged to provide these recommendations were their wide dissemination and implementation. Thus, the information generated can be used by each individual country to produce their own set of management guidelines and algorithms for treatment in primary care.

Arthroplasty in high grade congenital hip dislocation: Personal experience and review of the literature.

Total hip arthroplasty (THA) in congenital high grade hip dislocation often represents a problematic issue. Reviewing their selected cases and literature data, authors focus on some key points for this demanding surgery. Most important steps are acetabular positioning and surgical approach (exposure and release).

Periprosthetic bone density around fully hydroxyapatite coated femoral stem.

In this study, periprosthetic bone mineral density was measured at scheduled time intervals after surgery by dual energy x-ray absorptiometry in 21 patients to assess the history of bone density redistribution after femoral stem insertion. Measurements of changes in bone density with time were obtained for the regions of the greater trochanter, the lateral cortex, the tip, the medial cortex, and the calcar. In all regions, bone density decreased during the first 3 months after surgery; this was followed by a prolonged period of 18 to 30 months of bone gain, a subsequent period of steady state, and the final resumption of bone aging processes after the third postoperative year.

Analysis of the gait of adults who had residua of congenital dysplasia of the hip.

Twenty-one adult subjects who had symptomatic residua of unilateral congenital dysplasia of the hip, with various degrees of degenerative changes, were studied with respect to the physical and radiographic findings and gait performance. Three-dimensional body reconstruction; the Trendelenburg sign; spatiotemporal parameters of stride; ground-reaction forces; kinematics of the hip, knee, and ankle; moments of forces; and joint powers were evaluated bilaterally. The kinematic and kinetic parameters of the affected limb were compared with those of the unaffected limb and with those of the limbs of normal control subjects.

Dual X-ray absorptiometry for the evaluation of bone density from the proximal femur after total hip arthroplasty: analysis protocols and reproducibility.

Dual X-ray absorptiometry (DXA) instruments are now able to evaluate bone mineral density (BMD) of bone surrounding metal implants. The assessment of BMD around prosthetic components could provide additional information for the follow-up of total hip arthroplasty (THA). In this study, we evaluated the potential application of DXA in the field of THA.

Prophylaxis with indomethacin for heterotopic ossification after Chiari osteotomy of the pelvis.

One hundred patients who had painful dysplasia of the hip were treated with a Chiari osteotomy of the pelvis, and the postoperative radiographs were reviewed for the development of heterotopic ossification. Sixty patients did not receive indomethacin postoperatively, and eighteen (30 per cent) had heterotopic ossification of at least class 1; forty patients received indomethacin for two weeks postoperatively, and only three (8 per cent) of them had heterotopic ossification. This difference was significant (p < 0.
