Is two-stage revision surgery for infected hip arthroplasty worth the suffering, resources and results compared to one-stage?

Purpose: Periprosthetic joint infection (PJI) is the most serious complication of total hip arthroplasty. The treatment is usually revision in either 1 or 2 stages. This study analyses revision with impaction bone grafting for periprosthetic joint infection of the hip and compares 1- and 2-stage strategies.

Implant migration and bone mineral density measured simultaneously by low-dose CT scans: a 2-year study on 17 acetabular revisions with impaction bone grafting.

Background and purpose - Early postoperative implant migration predicts failure of joint replacements. Bone mineral density reflects bone quality and bone-graft incorporation. Implant migration and bone densitometry analysis usually require special equipment.

Low-dose CT-based implant motion analysis is a precise tool for early migration measurements of hip cups: a clinical study of 24 patients.

Background and purpose - Early implant migration is known to be a predictive factor of clinical loosening in total hip arthroplasty (THA). Radiostereometric analysis (RSA) is the gold standard used to measure early migration in patients. However, RSA requires costly, specialized imaging equipment and the image process is complex.

A 2- to 16-Year Clinical Follow-Up of Revision Total Hip Arthroplasty Using a New Acetabular Implant Combined With Impacted Bone Allografts and a Cemented Cup.

Background: Treatment of acetabular bone loss with impaction bone grafting (IBG) at revision total hip arthroplasty is highly dependent on mechanical stability and graft compression for clinical success. Here, we describe a new technique to further compress and stabilize the acetabular graft bed with a thin, perforated titanium shell.

Methods: We retrospectively analyzed 170 cases of acetabular revision arthroplasty 7 years (standard deviation 2.

A 3- to 18-Year Follow-Up of Revision Total Hip Arthroplasty With Impacted Bone Allografts and Cemented Lubinus SP II Stem. Clinical, Radiographic, and Survivorship Analysis With Comparison to the Literature.

Background: We present the first medium- to long-term follow-up of revision total hip arthroplasty using impaction bone grafting (IBG) combined with the matte and collared Lubinus SP II stem for cases of severe osteolysis and stem loosening.

Methods: Sixty-nine femoral revisions were identified for 67 patients consecutively operated with revision femoral arthroplasty using IBG and a cemented Lubinus SP II stem. The mean age was 69 years (standard deviation, 9.

Component dissociation after closed reduction of dual mobility sockets - a report of three cases.

Dual mobility sockets have been introduced in recent years to manage cases of potential instability after hip arthroplasty, and their use is increasing in revision surgery. We present 3 cases of intra-prosthetic dissociation between the outer polyethylene liner and the femoral head after closed reduction of prosthetic dislocation.
