Aims. Lumbar fusion is known to reduce the variation in pelvic tilt
between standing and sitting. A flexible lumbo-pelvic unit increases
the stability of total hip arthroplasty (THA) when seated by increasing
anterior clearance and acetabular anteversion, thereby preventing
impingement of the prosthesis. Lumbar fusion may eliminate this protective
pelvic movement. The effect of lumbar fusion on the stability of
total hip arthroplasty has not previously been investigated. Patients and Methods. The Medicare database was searched for patients who had undergone
THA and spinal fusion between 2005 and 2012. PearlDiver software
was used to query the database by the International Classification
of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) procedural
code for primary THA and lumbar spinal fusion. Patients who had
undergone both lumbar fusion and THA were then divided into three
groups: 1 to 2 levels, 3 to 7 levels and 8+ levels of fusion. The

Aims. The aim of this systematic review was to report the rate of dislocation
following the use of dual mobility (DM) acetabular components in
primary and revision total hip arthroplasty (THA). Materials and Methods. A systematic review of the literature according to the Preferred
Reporting Items for Systematic Reviews and Meta-analyses guidelines
was performed. A comprehensive search of Pubmed/Medline, Cochrane
Library and Embase (Scopus) was conducted for English articles between
January 1974 and March 2016 using various combinations of the keywords “dual
mobility”, “dual-mobility”, “tripolar”, “double-mobility”, “double
mobility”, “hip”, “cup”, “socket”. The following data were extracted
by two investigators independently: demographics, whether the operation
was a primary or revision THA, length of follow-up, the design of
the components, diameter of the femoral head, and type of fixation
of the acetabular component. Results. In all, 59 articles met our inclusion criteria. These included
a total of 17 908 THAs which were divided into two groups: studies
dealing with DM components in primary THA and those dealing with
these components in revision THA. The mean rate of
The aim of this retrospective study was to compare the functional
and radiological outcomes of bridge plating, screw fixation, and
a combination of both methods for the treatment of Lisfranc fracture
dislocations. A total of 108 patients were treated for a Lisfranc fracture
dislocation over a period of nine years. Of these, 38 underwent
transarticular screw fixation, 45 dorsal bridge plating, and 25
a combination technique. Injuries were assessed preoperatively according
to the Myerson classification system. The outcome measures included
the American Orthopaedic Foot and Ankle Society (AOFAS) score, the
validated Manchester Oxford Foot Questionnaire (MOXFQ) functional
tool, and the radiological Wilppula classification of anatomical

Aims. Uncemented implants are now commonly used at reimplantation of a two-stage revision total hip arthoplasty (THA) following periprosthetic joint infection (PJI). However, there is a paucity of data on the performance of the most commonly used uncemented femoral implants – modular fluted tapered (MFT) femoral components – in this setting. This study evaluated implant survival, radiological results, and clinical outcomes in a large cohort of reimplantation THAs using MFT components. Methods. We identified 236 reimplantation THAs from a single tertiary care academic institution from September 2000 to September 2020. Two designs of MFT femoral components were used as part of an established two-stage exchange protocol for the treatment of PJI. Mean age at reimplantation was 65 years (SD 11), mean BMI was 32 kg/m. 2. (SD 7), and 46% (n = 109) were female. Mean follow-up was seven years (SD 4). A competing risk model accounting for death was used. Results. The 15-year cumulative incidence of any revision was 24%. There were 48 revisions, with the most common reasons being

Aims. Adverse spinal motion or balance (spine mobility) and adverse pelvic mobility, in combination, are often referred to as adverse spinopelvic mobility (SPM). A stiff lumbar spine, large posterior standing pelvic tilt, and severe sagittal spinal deformity have been identified as risk factors for increased hip instability. Adverse SPM can create functional malposition of the acetabular components and hence is an instability risk. Adverse pelvic mobility is often, but not always, associated with abnormal spinal motion parameters.
