Letter to the Editor Comparison of acetabular reamings during hip resurfacing versus uncemented total hip arthoplasty
1. SA Brennan, JA Harty, C Gormley, SK O’Rourke. Comparison of acetabular reamings during hip resurfacing versus uncemented total hip arthoplasty. J Orthop Surg (Hong Kong) 2009;17:42–6. To the Editor: We read with interest the article by Brennan et al.1 They concluded that: “In hip resurfacing, the use of an appropriately small femoral component avoids oversizing the acetabular component and r...
متن کاملResults of uncemented porous-coated anatomic total hip replacement.
We reviewed a consecutive series of 241 uncemented, porous-coated anatomic (PCA) hip replacements at an average follow-up of five years (2 to 9). Of these, 32 had failed (13%), 26 at the acetabular component (11%) and six at the femoral component (2%). Acetabular failure was associated with local osteolysis and excessive polyethylene wear in 20 cases: in these histological examination showed gi...
متن کاملBirmingham hip resurfacing: is acetabular bone conserved?
Hip resurfacing is a bone-conserving procedure with respect to proximal femoral resection, but there is debate in the literature as to whether the same holds true for the acetabulum. We have investigated whether the Birmingham hip resurfacing conserves acetabular bone. Between 1998 and 2005, 500 Birmingham hip resurfacings were performed by two surgeons. Between 1996 and 2005 they undertook 700...
متن کاملHip Arthroplasty and its Revision in a Child: Case Report and Literature Review
Juvenile idiopathic arthritis is the leading cause of hip replacement in young children. However, arthroplasty in this population is challenging with several concerns about quality of the growing bone, young age for revision surgery, and difficulties in potential several revisions. In this study we introduce a case of a 12-year old who is one of the youngest patients to undergo revision hip art...
متن کاملComparison of acetabular reamings during hip resurfacing versus uncemented total hip arthroplasty.
PURPOSE To compare the quantity of bone removed from the acetabulum during resurfacing hip arthroplasty versus uncemented total hip arthroplasty (THA). METHODS 62 consecutive patients with osteoarthritis of the hip were prospectively studied. 24 men and 7 women aged 40 to 86 (mean, 59) years underwent Birmingham hip resurfacing. 13 men and 18 women aged 34 to 88 (mean, 61) years underwent unc...
