Increasingly, patients with bilateral hip arthritis wish to undergo staged total hip arthroplasty (THA). With the rise in demand for arthroplasty, perioperative risk assessment and counselling is crucial for shared decision making. However, it is unknown if complications that occur after a unilateral hip arthroplasty predict complications following surgery of the contralateral hip. We used nationwide linked discharge data from the Healthcare Cost and Utilization Project between 2005 and 2014 to analyze the incidence and recurrence of complications following the first- and second-stage operations in staged bilateral total hip arthroplasty (BTHAs). Complications included perioperative medical adverse events within 30 to 60 days, and infection and mechanical complications within one year. Conditional probabilities and odds ratios (ORs) were calculated to determine whether experiencing a complication after the first stage of surgery increased the risk of developing the same complication after the second stage.Aims
Patients and Methods
The Walch Type C dysplastic glenoid is characterized by excessive
retroversion. This anatomical study describes its morphology. A total of 29 shoulders with a dysplastic glenoid were analyzed.
CT was used to measure retroversion, inclination, height, width,
radius-of-curvature, surface area, depth, subluxation of the humeral
head and the Goutallier classification of fatty infiltration. The
severity of dysplasia and deficiency of the posterior rim of the
glenoid were recorded.Aims
Patients and Methods
Few reconstructive techniques are available for patients requiring
complex acetabular revisions such as those involving Paprosky type
2C, 3A and 3B deficiencies and pelvic discontinuity. Our aim was
to describe the development of the patient specific Triflange acetabular
component for use in these patients, the surgical technique and
mid-term results. We include a description of the pre-operative
CT scanning, the construction of a model, operative planning, and
surgical technique. All implants were coated with porous plasma
spray and hydroxyapatite if desired. A multicentre, retrospective review of 95 complex acetabular
reconstructions in 94 patients was performed. A total of 61 (64.2%)
were female. The mean age of the patients was 66 (38 to 85). The
mean body mass index was 29 kg/m2 (18 to 51). Outcome
was reported using the Harris Hip Score (HHS), complications, failures
and survival.Aims
Patients and Methods
We present an audit comparing our level I major trauma centre’s
data for a cohort of patients with hip fractures in the National
Hip Fracture Database (NHFD) with locally held data on these patients. A total of 2036 records for episodes between July 2009 and June
2014 were reviewed. Aims
Patients and Methods
There is uncertainty regarding the optimal means of thromboprophylaxis
following total hip and knee arthroplasty (THA, TKA). This systematic
review presents the evidence for acetylsalicylic acid (aspirin)
as a thromboprophylactic agent in THA and TKA and compares it with
other chemoprophylactic agents. A search of literature published between 2004 and 2014 was performed
in accordance with Preferred Reporting Items for Systematic Reviews
and Meta-Analyses guidelines. A total of 13 studies were eligible
for inclusion.Aims
Materials and Methods
The extent and depth of routine health care data
are growing at an ever-increasing rate, forming huge repositories
of information. These repositories can answer a vast array of questions.
However, an understanding of the purpose of the dataset used and
the quality of the data collected are paramount to determine the
reliability of the result obtained. This Editorial describes the importance of adherence to sound
methodological principles in the reporting and publication of research
using ‘big’ data, with a suggested reporting framework for future Cite this article:
