Dynamics of femoral bone remodelling in well fixed total hip arthroplasty. A 20-year follow-up of 20 hips.

The aim of our study was to investigate the dynamics of cortical thinning around well fixed cemented Muller straight stems without osteolysis at diffe...

Periprosthetic femoral fractures in total hip arthroplasty.
Periprosthetic fractures in total hip arthroplasty (THA) are a significant problem facing hip surgeons, and were responsible for revision surgery in 9% of single stage revision THAs recorded in the National Joint Registry of England and Wales (NJR) i

Removing a well-fixed femoral sleeve during revision total knee arthroplasty.
The following surgical technique describes a case of a 51-year-old man with severe juvenile rheumatoid arthritis that required a 2-stage revision of an infected revision total knee implant. The patient had previously been implanted with a revision ro

Bone remodelling of the scapula after a total shoulder arthroplasty.
According to Wolff's law, the changes in stress after a prosthesis implantation may modify the shape and internal structure of bone, thus compromising the long-term prosthesis fixation and, consequently, be a significant factor for glenoid loosening.

Computer aided densitometric image analysis of bone remodelling after total hip arthroplasty.
By means of a simple and inexpensive system, the computer aided densitometric image analysis (CADIA), we can now evaluate on X-ray film the effect of long term bone remodelling after total hip arthroplasties (THA). The results of CADIA system applied

Satisfying Results of Primary Hip Arthroplasty in Patients With Hip Dysplasia at a Mean Followup of 20 Years.
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

Removal of well-fixed fixed femoral stems.
The removal of a well-fixed prosthetic stem raises technical challenges. The objective is not only to remove the material, but also to prepare the implantation of a new prosthesis. Cemented stems are only very rarely unremovable; extraction of the ce
