This study aims to propose latitude cut deviation for differentiating hip arthroplasty types and evaluate its diagnostic utility in distinguishing total (THA) from hemiarthroplasty using radiography. After assessing various cup designs top manufacturers THA hemiarthroplasty, we conducted a retrospective on 40 patients (20 20 hemiarthroplasty). Three readers independently evaluated the radiograp...

Fractures of the femoral neck in elderly patients can be treated by internal fixation, hemiarthroplasty, or total hip arthroplasty (THA), and the treatment modality used should be determined on the basis of considerations of the degree of fracture displacement, age, functional demands, and the risk factors for surgery and anesthesia. We studied 85 active elderly patients who underwent minimally...

The purpose of this study was to compare total hip arthroplasty (THA) and hip resurfacing arthroplasty (HRA) with regard to the amount of acetabular bone stock removed and the ability to restore leg length and offset. Anteroposterior pelvis radiographs of 153 consecutive THAs and 84 consecutive HRAs were compared. Excluded patients were those with prior hip surgery, those in which a best-fit ci...

The utilization of autologous and allogeneic transfusions in total joint arthroplasties was to characterize patients who may benefit from giving preoperative blood donations. We conducted a retrospective chart review of 525 patients to document preoperative hematocrit, estimated blood loss, length of stay, transfusions, and medical comorbidities. Results of our review showed that total hip arth...

Newer arthroplasty designs claim to provide superior range of motion (ROM) and greater stability than their predecessors. However, there is no way to compare ROM of implant systems in an equivalent anatomical environment in a clinical setting. This study used computer-aided design to compare ROM after hip resurfacing, 28 mm THA, 36 mm THA, and anatomic dual mobility (ADM) THA in 3D models of 5 ...

Perioperative blood management remains a challenge during total hip arthroplasty (THA) and total knee arthroplasty (TKA). The purpose of this study was to systematically examine the relationship between body mass index (BMI) and perioperative blood transfusion during THA and TKA while attempting to resolve conflicting results in previously published studies. The authors retrospectively evaluate...

INTRODUCTION The objective of this study was to assess the number and magnitude of preoperative expectations and to correlate them with the degree of satisfaction expressed one year after Total Hip Arthroplasty (THA) or Total Knee Arthroplasty (TKA), in patients with severe and painful osteoarthritis (OA). MATERIALS AND METHODS Preoperative expectations (within 20 days prior to surgery) and p...

Amyloidoma of soft tissues is rare, and no previously published reports describe it in relation to hip prostheses. This article presents the case of a 78-year-old woman with a medical history of myelodysplasia and mild renal failure who underwent a right-sided metal-on-polyethylene total hip arthroplasty in 2003. She presented to the outpatient clinic with a 1-year history of right anterior thi...
