The purpose of this study is to evaluate the midterm results of cementless revision total hip arthroplasty (THA) using Wagner Cone Prosthesis. Between 1996 and 2007, 36 hips in 36 consecutive patients underwent femoral revision THA using Wagner Cone Prosthesis. Among them 28 hips were followed for more than 5 years. The mean age at revision surgery was 57 years and a mean follow-up was 7.6 years. The Paprosky classification system was used for preoperative bone loss evaluation. Clinical results were evaluated using Harris hip scores. For evaluation of the femoral component, radiolucent lines at bone-implant interfaces were evaluated and femoral component vertical subsidence was measured. Heterotopic bone formation and complications were also evaluated.Purpose
Material and Methods
The purpose of this study was to evaluate the results of two stage reconstruction for infected arthroplasty of hip joint and to know the risk factor for failures. From May 2004 to September 2011, 104 consecutive patients (105 hips) who underwent two stage reconstruction for the infected arthroplasty of hip joint were retrospectively evaluated. There were 60 hips with primary THA infection (Acute infection 22, Delayed infection 38), 4 hips with revision THA infection (Acute infection 1, Delayed infection 3), 20 hips with primary hemiarthroplasty infection (Acute infection 14, Delayed infection 6) and 24 hips with acute pyogenic coxitis. We evaluated the number of surgeries before two-stage reconstruction and also analysed the cultured pathogens. Mean follow duration after 2nd stage revision THA was 1.80 ± 1.76 years and average age at the time of 1st stage surgery (Debridement and PROSTALAC insertion) was 62.8 ± 14.3 years.Purpose:
Patients and Methods:
The purpose of this study is to know the peri-operative morbidity, clinical and radiographical outcomes of conversion THA from failed transtrochanter rotational osteotomy (TRO). From 2003 January to 2009 January, there were 18 hips(18 patients) who underwent conversion THA from TRO for osteonecrosis of the femoral head (ONFH) (Group I). The mean duration from TRO to conversion THA was 2.6 years. We made a matched control group of 18 primary THA for ONFH (Group II) and we evaluated perioperative morbidity and complications in each group. For the clinical evaluation, we checked Harris hip score (HHS) and WOMAC score. For the radiographical evaluation, we evaluated implant position, stability and osteolysis.Purpose
Patients and methods
This study was performed to evaluate the minimum 5-year clinical and radiological results of liner cementation into a stable acetabular shell using a metal-inlay, polyethylene liner during revision total hip arthroplasty (THA). Sixty-six hips (63 patients) that underwent revision THA using a metal-inlay polyethylene liner cementation were included. The causes of revision were; polyethylene wear in 37 cases, femoral stem loosening in 20 cases, ceramic head fracture in 4 cases, and recurrent dislocation in 5 cases. Clinical results were graded at final follow-up using Harris hip scores, and radiographs were evaluated to determine acetabular component inclination, the stabilities of acetabular and femoral components, correction of hip centers, and the progression of osteolysis.Introduction
Methods
Hip arthroplasty is a good treatment option for displaced femoral neck fracture in elderly patients. However, neuromuscular disease such as cerebral infarction or hemorrhage can be a concerning problem for THA since dislocation after operation can frequently occur. The purpose of this prospective study was to evaluate the functional results of modified minimally invasive (MI) two-incision total hip arthroplasty (THA) with the use of large-diameter (>38mm) metal-on-metal articulation in patients with muscle weakness. 19 consecutive patients (19 hips) with displaced femoral neck fracture with muscle weakness were enrolled. There were 11 patients with cerebral infarction, 4 patients with cerebral hemorrhage and 4 patients with Parkinson's disease. In the lateral position, an anterolateral approach between the gluteus medius and tensor fascia lata and a posterior approach between the piriformis and gluteus medius were used. Surgical morbidity, functional recovery, radiological implantation properties, range of motion (ROM) and complications were assessed.Purpose
