The purpose of this study was to identify the changes in untreated long head of the biceps brachii tendon (LHBT) after a rotator cuff tear and to evaluate the factors related to the changes. A cohort of 162 patients who underwent isolated supraspinatus with the preservation of LHBT was enrolled and evaluated. The cross-sectional area (CSA) of the LHBT on MRI was measured in the bicipital groove, and preoperative to postoperative difference was calculated at least 12 months postoperatively. Second, postoperative changes in the LHBT including intratendinous signal change, rupture, dislocation, or superior labral lesions were evaluated with seeking of factors that were correlated with the changes or newly developed lesions after rotator cuff repair.Aims
Methods
To determine the effectiveness of prone traction radiographs in predicting postoperative slip distance, slip angle, changes in disc height, and lordosis after surgery for degenerative spondylolisthesis of the lumbar spine. A total of 63 consecutive patients with a degenerative spondylolisthesis and preoperative prone traction radiographs obtained since 2010 were studied. Slip distance, slip angle, disc height, segmental lordosis, and global lordosis (L1 to S1) were measured on preoperative lateral standing radiographs, flexion-extension lateral radiographs, prone traction lateral radiographs, and postoperative lateral standing radiographs. Patients were divided into two groups: posterolateral fusion or posterolateral fusion with interbody fusion.Aims

Aims. Patients with multiple myeloma (MM) develop deposits in the spine
which may lead to vertebral compression fractures (VCFs). Our aim
was to establish which spinopelvic parameters are associated with
the greatest disability in patients with spinal myeloma and VCFs. Patients and Methods. We performed a retrospective cross-sectional review of 148 consecutive
patients (87 male, 61 female) with spinal myeloma and analysed correlations
between spinopelvic parameters and patient-reported outcome scores.
The mean age of the patients was 65.5 years (37 to 91) and the mean
number of vertebrae involved was 3.7 (1 to 15). Results. The thoracolumbar region was most commonly affected (109 patients,
73.6%), and was the site of most

Objectives. The purpose of this study was to develop an accurate, reliable and easily applicable method for determining the anatomical location of the joint line during revision knee arthroplasty. Methods. The transepicondylar width (TEW), the perpendicular distance between the medial and lateral epicondyles and the distal articular surfaces (DMAD, DLAD) and the distance between the medial and lateral epicondyles and the
The term mid-flexion instability has entered
the orthopaedic literature as a concept, but has not been confirmed
as a distinct clinical entity. The term is used freely, sometimes
as a synonym for flexion instability. However, the terms need to
be clearly separated. A cadaver study published in 1990 associated
joint line elevation with decreased stability at many angles of
flexion, but that model was not typical of clinical scenarios. The
literature is considered and it is proposed that the more common

This review summarises the evidence for the treatment
of displaced fractures of the femoral neck in elderly patients.
Results from randomised clinical trials and national register studies are
presented when available. . The advantages of arthroplasty compared with internal fixation
are supported by several studies. A number of studies contribute
to the discussions of total hip arthroplasty (THA) versus hemiarthroplasty
and unipolar versus bipolar hemiarthroplasty, but
no clear-cut evidence-based recommendation can be made. THA may
be particularly advantageous for active, lucid patients with a relatively
long life expectancy. For patients who are physiologically older,
hemiarthoplasty is probably satisfactory, and for the oldest patients with
more comorbidities, unipolar implants are considered to be sufficient.
If the hospital can support emergency THA surgery in sufficient
numbers and quality, there may be few patients who warrant bipolar
hemiarthroplasty. . The direct lateral approach reduces the risk of dislocation compared

The primary objective of this study was to compare migration of the cemented ATTUNE fixed bearing cruciate retaining tibial component with the cemented Press-Fit Condylar (PFC)-sigma fixed bearing cruciate retaining tibial component. The secondary objectives included comparing clinical and radiological outcomes and Patient Reported Outcome Measures (PROMs). A single blinded randomized, non-inferiority study was conducted including 74 patients. Radiostereometry examinations were made after weight bearing, but before hospital discharge, and at three, six, 12, and 24 months postoperatively. PROMS were collected preoperatively and at three, six, 12, and 24 months postoperatively. Radiographs for measuring radiolucencies were collected at two weeks and two years postoperatively.Aims
Methods
To report mid- to long-term results of Oxford mobile bearing domed lateral unicompartmental knee arthroplasty (UKA), and determine the effect of potential contraindications on outcome. A total of 325 consecutive domed lateral UKAs undertaken for the recommended indications were included, and their functional and survival outcomes were assessed. The effects of age, weight, activity, and the presence of full-thickness erosions of cartilage in the patellofemoral joint on outcome were evaluated.Aims

To establish whether there was a consensus among the members of the Hip Society (HS) on the role of direct anterior approach (DAA) contemporary primary total hip arthroplasty (THA). An online survey was sent to all 112 active and senior members of the HS, to which 71 members responded. The survey was constructed to determine whether they believed that evidence-based medicine proves, in modern clinical practice, that the DAA has significant benefits compared to risks when contrasted with other approaches. In addition, they were asked if they currently used the DAA.Aims

Aims. The aim of this study was to investigate the long-term clinical
and radiological outcome of patients who suffer recurrent injuries
to the anterior cruciate ligament (ACL) after reconstruction and
require revision surgery. Patients and Methods. From a consecutive series of 200 patients who underwent primary
reconstruction following rupture of the ACL, we identified 36 who
sustained a further rupture, 29 of whom underwent revision surgery.
Patients were reviewed prospectively at one, two, seven, 15 and
about 20 years after their original surgery. Primary outcome measures
were the number of further ruptures, the
