Controversy about the use of an anatomical total shoulder arthroplasty
(aTSA) in young arthritic patients relates to which is the ideal
form of fixation for the glenoid component: cemented or cementless.
This study aimed to evaluate implant survival of aTSA when used
in patients aged < 60 years with primary glenohumeral osteoarthritis (OA),
and to compare the survival of cemented all-polyethylene and cementless
metal-backed glenoid components. A total of 69 consecutive aTSAs were performed in 67 patients
aged < 60 years with primary glenohumeral OA. Their mean age
at the time of surgery was 54 years (35 to 60). Of these aTSAs,
46 were undertaken using a cemented polyethylene component and 23
were undertaken using a cementless metal-backed component. The age, gender,
preoperative function, mobility, premorbid glenoid erosion, and
length of follow-up were comparable in the two groups. The patients
were reviewed clinically and radiographically at a mean of 10.3
years (5 to 12, Aims
Materials and Methods
The aims of this study were to analyse the long-term outcome
of vascularised fibular graft (VFG) reconstruction after tumour
resection and to evaluate the usefulness of the method. We retrospectively reviewed 49 patients who had undergone resection
of a sarcoma and reconstruction using a VFG between 1988 and 2015.
Their mean follow-up was 98 months (5 to 317). Reconstruction was
with an osteochondral graft (n = 13), intercalary graft (n = 12),
inlay graft (n = 4), or resection arthrodesis (n = 20). We analysed
the oncological and functional outcome, and the rate of bony union
and complications.Aims
Patients and Methods
Reconstruction of the acetabulum after resection of a periacetabular
malignancy is technically challenging and many different techniques
have been used with varying success. Our aim was to prepare a systematic
review of the literature dealing with these techniques in order
to clarify the management, the rate of complications and the outcomes. A search of PubMed and MEDLINE was conducted for English language
articles published between January 1990 and February 2017 with combinations
of key search terms to identify studies dealing with periacetabular
resection with reconstruction in patients with a malignancy. Studies
in English that reported radiographic or clinical outcomes were
included. Data collected from each study included: the number and
type of reconstructions, the pathological diagnosis of the lesions,
the mean age and follow-up, gender distribution, implant survivorship, complications,
functional outcome, and mortality. The results from individual studies
were combined for the general analysis, and then grouped according
to the type of reconstruction. Aims

The aim of this meta-analysis was to assess the safety and efficacy
of collagenase clostridium histolyticum compared with fasciectomy
and percutaneous needle fasciotomy (PNF) for Dupuytren’s disease. We systematically searched PubMed, EMBASE, LILACS, Web of Science,
Cochrane, Teseo and the ClinicalTrials.gov registry for clinical
trials and cohort or case-control studies which compared the clinical
outcomes and adverse effects of collagenase with those of fasciectomy
or PNF. Of 1345 articles retrieved, ten were selected. They described
the outcomes of 425 patients treated with collagenase and 418 treated
by fasciectomy or PNF. Complications were assessed using inverse-variance
weighted odds ratios (ORs). Clinical efficacy was assessed by differences
between the means for movement of the joint before and after treatment.
Dose adjustment was applied in all cases.Aims

In the time since Letournel popularised the surgical
treatment of acetabular fractures, more than 25 years ago, there
have been many changes within the field, related to patients, surgical
technique, implants and post-operative care. However, the long-term
outcomes appear largely unchanged. Does this represent stasis or
have the advances been mitigated by other negative factors? In this
article we have attempted to document the recent changes within
the surgery of patients with a fracture involving the acetabulum,
outline contemporary management, and identify the major problem
areas where further research is most needed. Cite this article:
Instability remains a challenging problem in both primary and
revision total hip arthroplasty (THA). Dual mobility components
confer increased stability, but there are concerns about the unique
complications associated with these designs, as well as the long-term
survivorship. We performed a systematic review of all English language articles
dealing with dual mobility THAs published between 2007 and 2016
in the MEDLINE and Embase electronic databases. A total of 54 articles
met inclusion criteria for the final analysis of primary and revision
dual mobility THAs and dual mobility THAs used in the treatment
of fractures of the femoral neck. We analysed the survivorship and
rates of aseptic loosening and of intraprosthetic and extra-articular
dislocation.Aims
Materials and Methods
The aim of this study was to describe the epidemiology of closed
isolated fractures of the femoral shaft in children, and to compare
the treatment and length of stay (LOS) between major trauma centres
(MTCs) and trauma units (TUs) in England. National data were obtained from the Trauma and Audit Research
Network for all isolated, closed fractures of the femoral shaft
in children from birth to 15 years of age, between 2012 and 2015.
Age, gender, the season in which the fracture occurred, non-accidental
injury, the mechanism of injury, hospital trauma status, LOS and
type of treatment were recorded.Aims
Patients and Methods
Malalignment of the tibial component could influence the long-term survival of a total knee arthroplasty (TKA). The object of this study was to investigate the biomechanical effect of varus and valgus malalignment on the tibial component under stance-phase gait cycle loading conditions. Validated finite element models for varus and valgus malalignment by 3° and 5° were developed to evaluate the effect of malalignment on the tibial component in TKA. Maximum contact stress and contact area on a polyethylene insert, maximum contact stress on patellar button and the collateral ligament force were investigated.Objectives
Methods
The posterior malleolus component of a fracture
of the ankle is important, yet often overlooked. Pre-operative CT scans
to identify and classify the pattern of the fracture are not used
enough. Posterior malleolus fractures are not difficult to fix.
After reduction and fixation of the posterior malleolus, the articular
surface of the tibia is restored; the fibula is out to length; the
syndesmosis is more stable and the patient can rehabilitate faster.
There is therefore considerable merit in fixing most posterior malleolus
fractures. An early post-operative CT scan to ensure that accurate
reduction has been achieved should also be considered. Cite this article:
We assessed the long-term (more than ten-year) outcomes of the
Kudo type-5 elbow prosthesis in patients with rheumatoid arthritis
(RA). We reviewed 41 elbows (Larsen Grade IV, n = 21; Grade V, n =
20) in 31 patients with RA who had undergone a Kudo type-5 total
elbow arthroplasty (TEA) between 1994 and 2003, and had been followed
up for more than ten years. The humeral component was cementless
and the all-polyethylene ulnar component cemented in every patient. Clinical
outcome was assessed using the Mayo elbow performance score. We
calculated the revision rate and evaluated potential risk factors
for revision. The duration of follow-up was a mean 141 months (120
to 203).Aims

The aim of this study was to compare the post-operative radiographic
and clinical outcomes between kinematically and mechanically aligned
total knee arthroplasties (TKAs). A total of 60 TKAs (30 kinematically and 30 mechanically aligned)
were performed in 60 patients with varus osteoarthritis of the knee
using a navigation system. The angles of orientation of the joint
line in relation to the floor, the conventional and true mechanical
axis (tMA) (the line from the centre of the hip to the lowest point
of the calcaneus) were compared, one year post-operatively, on single-leg
and double-leg standing long leg radiographs between the groups.
The range of movement and 2011 Knee Society Scores were also compared
between the groups at that time.Aims

Radial head arthroplasty (RHA) may be used in the treatment of
non-reconstructable radial head fractures. The aim of this study
was to evaluate the mid-term clinical and radiographic results of
RHA. Between 2002 and 2014, 77 RHAs were implanted in 54 men and 23
women with either acute injuries (54) or with traumatic sequelae
(23) of a fracture of the radial head. Four designs of RHA were
used, including the Guepar (Small Bone Innovations (SBi)/Stryker;
36), Evolutive (Aston Medical; 24), rHead RECON (SBi/Stryker; ten)
or rHead STANDARD (SBi/Stryker; 7) prostheses. The mean follow-up
was 74.0 months (standard deviation (Aims
Patients and Methods
Non-traumatic osteonecrosis of the femoral head
is a potentially devastating condition, the prevalence of which
is increasing. Many joint-preserving forms of treatment, both medical
and surgical, have been developed in an attempt to slow or reverse
its progression, as it usually affects young patients. However, it is important to evaluate the best evidence that is
available for the many forms of treatment considering the variation
in the demographics of the patients, the methodology and the outcomes
in the studies that have been published, so that it can be used
effectively. The purpose of this review, therefore, was to provide an up-to-date,
evidence-based guide to the management, both non-operative and operative,
of non-traumatic osteonecrosis of the femoral head. Cite this article:
