ABSTRACT: Aim: The
objective of the study was to report the progressive complications of hip joint
disease in a population of sickle cell. Materials and Methods: A
descriptive and retrospective study from 2002 to 2008: A case of 31 sickle cell
subjects having presented an advanced osteonecrosis of the femoral head. All
the patients benefited from an arthroplasty in adulthood with a radiographic
monitoring in immediate post operative before and after one year. The sickle
cell subjects were compared to a non sickle cell control group of 37 patients
according to the same criteria. The analysis had included considerations of the
environment and the position of the prosthetic parts, as well as additional
modifications. The types of complications and the moment at which they occur
were indexed and analyzed using a statistical test of FISHER with a threshold
of significance level p Results: The average age of sickle cell patients was 35 years and non sickle cell
disease sufferers, 51, with a male predominance. Indications for surgery were
dominated by coxarthroses, 31 cases
(100%) in sickle cell disease sufferers and 17 cases (46%) among the control
group. All our patients underwent a radiological control in the immediate
postoperative. They were fewer between 6 months and 1 year (19%). The immediate
complications were dominated by fractures 2 cases in non sickle cell disease
sufferers. The complications before one year were marked by a predominance of
dislocation, 3 cases in the non sickle cell population against 2 cases in
sickle cell population. The loosening were the most observed complications in
both populations after a year and more (5 cases in sickle cell disease sufferers
and 6 cases in non sickle cell disease sufferers). Conclusion: The
evolutionary complications of joint replacements in sickle cell subjects are
not more frequent than in non sickle cell subjects.
