Abstract
Background Fractured stem of the hip prosthesis is well documented in the literature. Although it is rare, it is considered as a challenging problem. Many techniques have been described to solve this problem. Purpose of the Study. Evaluation of the effect of anterolateral bone window for extraction of the cemented femoral stem of hemiarthroplasty in revision total hip replacement. Methods The study included eight revision hip arthroplasties in eight patients, with a broken stem of cemented (Thompson) hemiarthroplasty, which has been revised by the anterolateral proximal femoral window. All cases received cemented cups and cement-in-cement stems, except one case who received cementless long stem. Clinical follow-up of cases by Harries hip score (HHS) and X-ray. Results Functional improvement of HHS of all cases, with no signs of loosening, after a mean follow-up period of 1.5 years. Conclusion Extraction of broken stem is a challenging procedure. Many techniques have been described for revision of cases with a fractured stem of hip prosthesis, but we think that the anterolateral femoral bone window is a reproducible technique due to the characteristics of simplicity, short-time procedure, less invasive, not requiring extra instruments, and can be successful for most patients.
Highlights
Fractured stem of the hip prosthesis is well documented in the literature with an incidence rate between 0.23 and 11% [1, 2]. ree-dimensional analysis of stresses around the stem showed the highest concentration of stresses on the lateral aspect of the middle third, so fracture usually starts at the anterolateral aspect of the stem [3]
There are some very few cases that may occasionally present with a broken stem especially with older designs that are used in the past such as cemented ompson hemiarthroplasty, which is still used in some countries for fractured neck of femur in the older age group of patients
We presented eight cases of revision cemented unipolar hemiarthroplasty after broken cemented stems of ompson hemiarthroplasty, in which we used the anterolateral bone window techniques for extraction of the distal portion of stem
