Total Hip Replacement Using a Highly Cross-Linked Polyethylene Liner in Asians with Small Acetabulum

Total hip replacement using a highly crosslinked polyethylene liner in Asians with small acetabulum.

PURPOSE To evaluate the medium-term outcomes of total hip replacement (THR) using a thin highly cross-linked polyethylene (HXLPE) liner in an Asian population. METHODS Medical records of 20 men and 44 women aged 26 to 80 (mean, 59) years who underwent 80 THRs using a thin HXLPE liner by a single surgeon were reviewed. Indications for THR included dysplasia (n = 26), avascular necrosis (n=26),...

Total Hip Arthroplasty Using Metal Head on a Highly Cross-linked Polyethylene Liner

PURPOSE This retrospective study was performed to evaluate the clinical results and measure polyethylene liner wear in total hip arthroplasty (THA) with highly cross-linked polyethylene. MATERIALS AND METHODS Except for patients who had died or were unable to have follow-up at least 2 years, 60 of 78 hips that underwent THA were included this study. The mean age was 64.5 years (range, 25-81 y...

Acetabular Liner for Total Hip Arthroplasty at Five Years Clinical Performance of a Durasul Highly Cross-Linked Polyethylene

Rim cracking of the cross-linked longevity polyethylene acetabular liner after total hip arthroplasty.

BACKGROUND Studies have suggested that cross-linked polyethylene bearings reduce wear rates from 40% to 100% compared with conventional polyethylene. However, the reduced mechanical properties of highly cross-linked polyethylene have the potential to be a limiting factor in device performance. We reviewed a series of retrieved acetabular liners with a fracture of the superior rim to assess the ...

Reconstruction of the Acetabulum in Developmental Dysplasia of the Hip in Total Hip Replacement

Developmental dysplasia of the hip (DDH) or congenital hip dysplasia (CDH) is the most prevalent developmental childhood hip disorder. It includes a wide spectrum of hip abnormalities ranging from dysplasia to subluxation and complete dislocation of the hip joint. The natural history of neglected DDH in adults is highly variable. The mean age of onset of symptoms is 34.5 years for dysplastic DD...
