PURPOSE To evaluate the causes and frequency of the squeaking sound in ceramic-on-ceramic THA. MATERIALS AND METHODS This study included 61 hips of 50 patients who underwent ceramic-on-ceramic THA in our hospital from March 1999 to April 2005. The average age at the time of operation was 57.6 years. The average duration of follow-up was 69.5 months. Three(More)
The Prodigy femoral component was extensively coated along its entire length, except for a smooth bullet-shaped distal tip. At a minimum 5 year followup we compared the results of that stem to those of a proximally coated first generation femoral component at comparable followup to address the question of which design performed better. For the extensively(More)
BACKGROUND The aim of this study was to investigate the causes of the high revision rate of the hydroxyapatite-coated Anatomique Benoist Girard (ABG-I) prosthesis. METHODS We performed 204 total hip arthroplasties (THAs) at our hospital between March 1992 and December 1996. Of the 204 THA patients, 129 were followed up; the mean duration of follow-up was(More)
A hip arthroscopy technique for the reduction and internal fixation of a displaced femoral head fracture is presented. Open treatment is often required for femoral head fractures. However, it is shown below how large fragments of a femoral head fracture-dislocation were reduced and internally fixated using hip arthroscopy. This was performed in the supine(More)
BACKGROUND To understand why hydroxyapatite (HA)-coated acetabular cups did not produce satisfactory results, we measured the extent of bone ongrowth and HA absorption of the retrieved cups. METHODS Between March 1992 and June 1998, a total of 289 patients underwent total hip arthroplasty with an HA-coated ABG (Anatomical Benoist Giraud) prosthesis in our(More)
BACKGROUND To evaluate the effectiveness of minimally invasive surgery total hip arthroplasty (THA) using the two-incision technique as described by Mears. METHODS From January 2003 to December 2006, sixty-four patients underwent total hip arthroplasty using the one-incision (group I) and two-incision (group II) technique by one surgeon. There were 34(More)
PURPOSE We aimed to evaluate the results of surgical treatment of periprosthetic femoral fractures in cementless total hip arthroplasty (THA). MATERIALS AND METHODS From June 2002 to May 2012, 40 patients who could be followed-up for more than 1 year after surgery were enrolled in this study. The mean duration of follow-up was 28.5 months (range, 15-97(More)
PURPOSE To evaluate the clinical and radiological results, as well as the survival rate, associated with total hip arthroplasty using a hydroxyapatite (HA)-coated anatomical femoral stem at a follow-up of ≥12 years. MATERIALS AND METHODS From April 1992 to May 1997, 86 patients (102 hips) underwent total hip arthroplasty with a HA-coated ABG I (Anatomical(More)
PURPOSE The purpose of this study was to evaluate if the femoral head's size has an impact on dislocation rates following total hip arthroplasty (THA). MATERIALS AND METHODS Five hundreds forty-three THA performed using a posterolateral approach in our hospital and followed up more than 6 months were included in this study. We evaluated dislocation rates(More)
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(More)
