Unlabelled: We present an update of 19 acetabular reconstructions, performed with a cemented total hip arthroplasty and impaction bone-grafting, in situ at the time of our previous report. At a mean follow-up of 30 years (range, 27 to 35 years), no additional patients were lost to follow-up. Two patients (3 reconstructions) died for reasons unrelated to the hip surgery.
View Article and Find Full Text PDFBackground: Developmental dysplasia of the hip (DDH) is a common cause of secondary osteoarthritis (OA) in younger patients, and when end-stage OA develops, a THA can provide a solution. Different options have been developed to reconstruct these defects, one of which is impaction bone grafting combined with a cemented cup. To determine the true value of a specific technique, it is important to evaluate patients at a long-term followup.
View Article and Find Full Text PDFIntroduction: Despite improvements in the technique of femoral impaction bone grafting, reconstruction failures still can occur. Therefore, the aim of our study was to determine risk factors for the endpoint re-revision for any reason.
Methods: We used prospectively collected demographic, clinical and surgical data of all 202 patients who underwent 208 femoral revisions using the X-change Femoral Revision System (Stryker-Howmedica), fresh-frozen morcellised allograft and a cemented polished Exeter stem in our department from 1991 to 2007.
Background And Purpose: Very little has been published on the outcome of femoral cemented revisions using a third-generation cementing technique. We report the medium-term outcome of a consecutive series of patients treated in this way.
Patients And Methods: This study included 92 consecutive cemented femoral revisions performed in our department with a third-generation cementing technique and without instrumented bone impaction grafting between 1996 and 2007.
Background: The increasing number of total hip arthroplasties (THAs) performed in younger patients will inevitably generate larger numbers of revision procedures for this specific group of patients. Unfortunately, no satisfying revision method with acceptable survivorship 10 years after revision has been described for these patients so far.
Questions/purposes: The purposes of this study were to (1) analyze the clinical outcome; (2) complication rate; (3) survivorship; and (4) radiographic outcome of cemented revision THA performed with impaction bone grafting (IBG) on both the acetabular and femoral sides in one surgery in patients younger than 55 years old.
Purpose: It is often a difficult decision whether it is safe to perform revision hip surgery in a patient of 80 years and older. Therefore we evaluated the results of cemented revisions in these elderly patients.
Methods: Clinical data, radiographs and complications of 49 consecutive cup and/or stem revisions in 48 patients were prospectively collected.
Introduction: For the revision of failed acetabular components impaction bone grafting (IBG) with a cemented cup is a well known technique. Claims have been made that this is a biological reconstruction technique, restoring the bone stock loss and thereby facilitating future revisions. However, there are no scientific data proving this claim.

However, most available cemented stems are too long to fit in the existing cement mantle. We evaluated the medium-term outcomes of the 125 mm short tapered polished stem (Exeter Short Revision Stem (SRS)) with a 44 mm offset specifically designed to facilitate cement-in-cement revisions of hip arthroplasties.

Case Description And Methods: Due to the high risk of recurrent bleeding and limitations regarding full weight bearing of the stump, a normal socket fitting process was not possible. Using a multidisciplinary approach, a prosthesis was designed to enable full weight bearing in a flexed knee position with ischial tuberosity support to prevent full weight bearing on the tibial part of the stump.
Background: Surgical treatment options for sternoclavicular joint luxations described in the literature are numerous, although all have limitations. Therefore, there is no favorable surgical treatment for sternoclavicular luxations when nonoperative treatment has failed.
Description Of Technique: We developed the polydioxanone (PDS) envelope plasty, a modification of the figure-of-eight technique, using a PDS ligament.
Background: The number of total hip arthroplasties in patients under 30 years is increasing over the years. Almost all of them will face at least one or more future revisions in their life. Therefore, the implant used should have a high survival rate, and needs to be easily revisable resulting in a low re-revision rate.

The present update study shows the results after twenty to twenty-eight years. Eight additional cups had to be revised--four because of aseptic loosening, three because of wear, and one during a revision of the stem.

Background: Loosening of acetabular components often leads to bony defects. Management of extensive acetabular bone loss in hip revision arthroplasty can be a tremendous challenge.
Questions/purposes: We asked whether a reconstruction with impacted bone grafts will provide a durable and pain-free function in extensive acetabular defects.
Objective: To determine the long-term results of primary cemented total hip arthroplasty in patients under the age of 40. In cases of acetabular defects, initial reconstruction with bone impaction grafting was performed.
Design: Cohort analysis.
Background And Purpose: Total hip arthroplasties in young patients have lower long-term survival rates than in older patients. We evaluated the use of a unique treatment protocol in patients aged between 40 and 50 years. In all cases we used a cemented THA, and for acetabular deficiencies we also used impacted bone grafts together with a cemented cup.

However, in cases of acetabular bone stock defects, we also use bone impaction grafting. We prospectively followed 130 patients with 175 cemented cups; no patients were lost to followup.

After a minimal follow-up of 2 years, 33 hips were studied. In total hip arthroplasty after failed osteotomy, when compared with total hip arthroplasty after failed bone impaction grafting, clinical and radiologic outcome was less favorable, more complications were observed, and there was a higher revision rate for a technically more demanding procedure.

The bone impaction grafting technique in combination with a cemented total hip can restore the bone stock in these patients, but do these reconstructions yield satisfying long-term results? We used this technique in 28 hips (22 consecutive patients). The degree of dislocation was graded preoperatively as Crowe I in five hips, Crowe II in eight hips, Crowe III in nine hips, and Crowe IV in four hips.

Bone morphogenetic proteins (BMPs) accelerate bone repair in experimental and clinical conditions. Impacted Morsellized Cancellous Bone grafts (MCB) are successfully used to reconstruct bone defects after failed hip implants. The main question in this study was if BMP-7 (OP-1) mixed with MCB could accelerate the incorporation of MCB and prevents the formation of a soft tissue interface after remodeling of the MCB.
View Article and Find Full Text PDFBone impaction grafting has been advocated for reconstruction of femoral head osteonecrosis. However, bone grafts do not prevent the progression of collapse and subsequent disabling osteoarthritis in late-stage osteonecrosis. We hypothesized reconstruction of large subchondral defects with a mix of impacted morsellized cancellous bone grafts and calcium phosphate cement would afford mechanical stability allowing remodeling into new bone without femoral head collapse.

Background: Osteonecrosis of the distal portion of the femur produces a segment of dead bone in the weight-bearing portion of the femoral condyle, frequently associated with subchondral fracture and collapse and eventually resulting in secondary osteoarthritis. Treatment of these late stages of osteonecrosis in the knee can be problematic. The purpose of the present study was to evaluate a new surgical technique in which the subchondral osteonecrotic lesion is removed.

Reconstructing large loaded bone defects with ceramic bone graft extenders is tempting considering the expected future donor bone shortage. However, whether there are negative effects is unknown. Standardized large defects in the acetabulum of goats were created and subsequently reconstructed with metal mesh and impacted morselized cancellous bone grafts or a 50/50% volume mixture of tricalcium phosphate-hydroxyapatite granules and morselized cancellous bone grafts using the bone impaction grafting technique.
