Abstract
It remains a matter of debate whether to fix or to replace subcapital fractures of femur, particularly the displaced one’s. Orthopaedic surgeons face the challenge of providing the best treatment for intracapsular fracture of the femur. Most authors agree that in young demanding patients with no displacement fracture, the internal fixation techniques should be used with the proper anatomical reduction and without delay. However the risk of reoperation is somehow near 30%. On the other hand patients with a displaced fracture will need to consider a few more options like the arthroplasty.
In this 5 year retrospective study we compare the mortality, morbidity, functional status of patients following each of the principal methods of treatment for subcapital fractures of the femur.
We could in this way observe a group of 48 patients operated between 1998 and 2002 and wich we divided in two sub-groups according to the AO classification of their fractures.
The first group had 20 patients all classified as B1 fractures with no displacement, they were treated mainly by internal fixation. The second group had 28 patients with B3 fractures with displacement, they were treated mainly by replacement of the femoral head. All of these patients were followed in an average of 20 and 24 months respectively.
We found no significant difference in the mortality rate, average age, sex, ethiology in the two sub-groups, but the reoperation rate of the internal fixation, mainly the first sub-group was four times the arthroplasty. The internal fixation did have fewer immediate postoperative complications and shorter hospital stay. We also did find that in the first group we had 6 revisions because implant failure and non-union, in the second group we had 2 revisions because of implant failure. Patients submitted to internal fixation had, in long term, more severe pain and impaired walking than those with arthroplasty. The average Harris Hip Score was 79 for the first group and 82 for the second group.
We can conclude, although this is a very small sample, as in other series that the displaced fractures have a more consensual treatment specially the older patients in which the treatment of choice is arthroplasty. In the non displaced fractures the first choice is internal fixation, but because of the high rate of the non union the doubt is always present whether to fix or replace.
Is our patient willing to stand for that?
