The direct posterior approach with subperiosteal dissection of the paraspinal muscles from the vertebrae is considered to be the standard approach for the surgical treatment of adolescent idiopathic scoliosis (AIS). We investigated whether or not a minimally-invasive surgery (MIS) technique could offer improved results. Consecutive AIS patients treated with an MIS technique at two tertiary centres from June 2013 to March 2016 were retrospectively included. Preoperative patient deformity characteristics, perioperative parameters, power of deformity correction, and complications were studied. A total of 93 patients were included. The outcome of the first 25 patients and the latter 68 were compared as part of our safety analysis to examine the effect of the learning curve.Aims
Methods
The aim of this study was to report a retrospective, consecutive
series of patients with adolescent idiopathic scoliosis (AIS) who
were treated with posterior minimally invasive surgery (MIS) with
a mean follow-up of two years ( We prospectively collected the data of 70 consecutive patients
with AIS treated with MIS using three incisions and a muscle-splitting
approach by a single surgeon between June 2013 and February 2016
and these were retrospectively reviewed. There were eight male and
62 female patients with a mean age of 15 years (Aims
Patients and Methods
This study aimed to determine the diagnostic performance of radiographic
criteria to detect aseptic acetabular loosening after revision total
hip arthroplasty (THA). Secondary aims were to determine the predictive
values of different thresholds of migration and to determine the
predictive values of radiolucency criteria. Acetabular component migration to re-revision was measured retrospectively
using Ein-Bild-Rontgen-Analyse (EBRA-Cup) and manual measurements
(Sutherland method) in two groups: Group A, 52 components (48 patients) found
not loose at re-revision and Group B, 42 components (36 patients)
found loose at re-revision between 1980 and 2015. The presence and
extent of radiolucent lines was also assessed.Aims
Patients and Methods
The purpose of this study was to determine the sensitivity, specificity
and predictive values of previously reported thresholds of proximal
translation and sagittal rotation of cementless acetabular components
used for revision total hip arthroplasty (THA) at various times
during early follow-up. Migration of cementless acetabular components was measured retrospectively
in 84 patients (94 components) using Ein-Bild-Rontgen-Analyse (EBRA-Cup)
in two groups of patients. In Group A, components were recorded
as not being loose intra-operatively at re-revision THA (52 components/48
patients) and Group B components were recorded to be loose at re-revision
(42 components/36 patients).Aims
