Bone stock-preserving short stem prostheses have gained importance in total hip arthroplasty (THA) with the use of minimally invasive surgical procedures. Because of their metaphyseal fixation and their dependency on the calcar radius, it is unknown whether the femoral offset can be reproduced with the same accuracy following short stem vs standard stem THA. This study clarifies whether it is p...

BACKGROUND Few, if any data are available are available regarding the time-trends in characteristics of patients who have undergone primary THA. Our objective was to examine the time-trends in key demographic and clinical characteristics of patients undergoing primary total hip arthroplasty (THA). METHODS We used the data from the Mayo Clinic Total Joint Registry from 1993-2005 to examine the...

BACKGROUND AND PURPOSE Pediatric hip diseases account for 9% of all primary hip arthroplasties in the Norwegian Arthroplasty Register. We wanted to validate the diagnosis as reported to the register and to assess the quality of life of these patients after hip replacement. PATIENTS AND METHODS 540 patients accepted to participate in this follow-up study (634 hips). All were less than 40 years...

OBJECTIVE To evaluate sex differences in the clinical and structural presentation, and natural history of hip OA. METHODS A multicentre, prospective, longitudinal, five year follow up study of 508 patients (302 women, 206 men, mean age 63 (7) years) with painful hip OA. Data collected were baseline demographics, symptomatic, therapeutic, and structural variables; symptomatic variables and cha...

BACKGROUND Both surgeon and hospital procedure volumes have been found to be associated with total hip arthroplasty (THA) outcomes. However, little research has been conducted on the relative influence. We studied the association between THA survivorship and both hospital and surgeon procedure volumes, considering their relative impact. METHODS A population-based cohort included all patients ...

BACKGROUND: Nowadays total hip arthroplasty (THA) is the method of choice for treatment late stages osteonecrosis femoral head (OFH) and osteoarthritis (OA) joint.
 OBJECTIVE: To evaluate efficacy complication pattern THA in OFH OA.
 MATERIALS AND METHODS: The study included 74 patients who underwent primary OA IIIIV (Kellgren Lawrence classification) (ARCO classification). Group 1 34...

Intraoperative proximal femoral fracture, one of the most common complications of total hip arthroplasty (THA), occurs more often in cementless procedures and can affect rehabilitation, hospitalization time, and cost of treatment. The goal of this study was to identify risk factors for intraoperative proximal femoral fracture in THA to identify high-risk groups preoperatively and minimize the i...

The position of the acetabular cup is a major factor in the long-term outcome of total hip arthroplasty (THA). Malpositioning of the acetabular cup frequently has been reported with the use of a minimally invasive implantation technique. It remains unclear whether the limited visibility or the increased retractor traction and thus tilting of the pelvis during cup implantation is the cause. This...
