BACKGROUND The purpose of the present study is to use a statewide, population-based data set to identify mortality rates at 30-day and 1-year postoperatively following total hip arthroplasty (THA) and hemiarthroplasty (HA) for displaced femoral neck fractures. The secondary aim of the study is to determine whether arthroplasty volume confers a protective effect on the mortality rate following f...

In primary total hip arthroplasty (THA), dual-modular stems were introduced to better restore stability, femoral offset, and leg length. This entry highlights the gathered knowledge about related complications in combinations with titanium (Ti) cobalt-chrome (CoCr) exchangeable necks. The reasons for a modular neck failure are multifactorial. Some of still on market despite fact th these design...

OBJECTIVE To study the HRQOL in veterans with prevalent total knee arthroplasty (TKA) or total hip arthroplasty (THA) and compare them with age- and gender-matched US population and control veteran population without these procedures. METHODS A cohort study and cross-sectional survey on veterans obtained demographics and HRQOL with Short-Form 36 for veterans (SF-36V). Veterans were categorize...

Background and purpose - According to previous Nordic Arthroplasty Register Association (NARA) data, the 10-year implant survival of cemented total hip arthroplasties (THAs) is 94% in patients aged 65-74 and 96% in patients aged 75 or more. Here we report a brand-level comparison of cemented THA based on the NARA database, which has not been done previously. Patients and methods - We determined...

IMPORTANCE There are concerns about increased mortality in patients with metal-on-metal bearings in total hip arthroplasty (THA). OBJECTIVE To determine the mortality and the morbidity in patients with metal-on-metal articulations (MOM THA) compared to patients with non-metal-on-metal articulations (non-MOM THA) after primary total hip arthroplasty. DATA SOURCES Search of PubMed, MEDLINE, E...

BACKGROUND The number of septic total hip arthroplasty (THA) revisions is increasing continuously, placing a growing financial burden on hospitals. Orthopedic departments performing septic THA revisions have no basis for decision making regarding resource allocation as the costs of this procedure for the departments are unknown. It is widely assumed that septic THA procedures can only be perfor...

OBJECTIVE Subtle deformities of the hip joint are implicated in the etiology of osteoarthritis (OA) of the hip. Parameters that quantify these deformities may aid understanding of these associations. We undertook this study to examine relationships between such parameters and the 19-year risk of total hip arthroplasty (THA) for end-stage OA. METHODS A new software program designed for measuri...

OBJECTIVES To determine chronic opioid use pre-THA (total hip arthroplasty) and post-THA, and risk factors for persistent or new chronic opioid use post-THA. DESIGN Retrospective cohort study. SETTING Australian Government Department of Veterans' Affairs health claims database. PARTICIPANTS 9525 patients who had an elective unilateral THA between 1/01/2001 and 12/31/2012. PRIMARY OUTCOM...

Various complications occur during total hip arthroplasty (THA). It is common to implement trial treatments of various implants during THA. Here we report on 2 cases in which the trial femoral head fell into the pelvis and migrated during THA. The trial head was not retrieved but left inside in one case, while the other presented the opportunity for a possible retrieval. It is important to reco...
