Brief summary

The hip prosthesis market is constantly growing with the number of prostheses reaching 949,000 in 2019. Along with this, there is also an increase in interest in short stems also called shortened stems. Thus on Pubmed, in 5 years, 171 publications have been listed. Thus, it seems interesting to study and analyze the performance of the shortened stem used in the Department of Orthopedic Surgery and Traumatology of the University Hospitals of Strasbourg and to compare them with the results of the literature.

Detailed description

The objective of this study is to observe the appearance of shortened stem radiological abnormalities at least 2 years postoperatively.

Inclusion criteria

* Male or female (age ≥18 years old) * Subject operated for first-line THA for an indication of centric hip osteoarthritis (including minor dysplasia and coxa profunda) and aseptic osteonecrosis of the femoral head * Subject who received a THA between January 2015 and December 2019 * Subject who received an uncemented shortened SCC or SCLA femoral stem * Radiological data available: pre-operative, immediate post-operative and post-operative at a minimum of 2 years (≥24 months) * Subject not objecting to the reuse of their data for scientific research purposes.

Exclusion criteria

* Subject having expressed its opposition to the reuse of its data for scientific research purposes. * Patient operated for inflammatory pathology or major dysplasia, recovery * Associated fractures or sequelae of fractures * Patient having presented intraoperative or early complications such as infections, intraoperative fracture, dislocation of the hip following the installation of the THA * Revision of hip arthroplasty during the study follow-up period for a cause not studied in the study.
