This study describes the Osseointegration Group of Australia’s
Accelerated Protocol two-stage strategy (OGAAP-1) for the osseointegrated
reconstruction of amputated limbs. We report clinical outcomes in 50 unilateral trans-femoral amputees
with a mean age of 49.4 years (24 to 73), with a minimum one-year
follow-up. Outcome measures included the Questionnaire for persons
with a Trans-Femoral Amputation, the health assessment questionnaire
Short-Form-36 Health Survey, the Amputation Mobility Predictor scores
presented as K-levels, 6 Minute Walk Test and timed up and go tests.
Adverse events included soft-tissue problems, infection, fractures
and failure of the implant.Aims
Patients and Methods
The injured anterior cruciate ligament (ACL) is thought to exhibit an impaired healing response, and attempts at surgical repair have not been successful. Connective tissue growth factor (CTGF) is reported to be associated with wound healing, probably through transforming growth factor beta 1 (TGF-β1). A rabbit ACL injury model was used to study the effect of CTGF on ligament recovery. Quantitative real-time PCR (qRT-PCR) was performed for detection of changes in RNA levels of TGF-β1, type 1 collagen (COL1), type 2 collagen (COL2), SRY-related high mobility group-box gene9 (SOX9), tissue inhibitor of metalloproteinase-1 (TIMP-1) and matrix metallopeptidase 13 (MMP-13). Expression of related proteins was detected by Western blotting.Objectives
Methods
Intercalary allografts following resection of a primary diaphyseal
tumour have high rates of complications and failures. At our institution
intercalary allografts are augmented with intramedullary cement
and fixed using compression plating. Our aim was to evaluate their
long-term outcomes. A total of 46 patients underwent reconstruction with an intercalary
allograft between 1989 and 2014. The patients had a mean age of
32.8 years (14 to 77). The most common diagnoses were osteosarcoma
(n = 16) and chondrosarcoma (n = 9). The location of the tumours
was in the femur in 21, the tibia in 16 and the humerus in nine. Function
was assessed using the Musculoskeletal Tumor Society (MSTS) scoring
system and the Toronto Extremity Salvage Score (TESS). The survival
of the graft and the overall survival were assessed using the Kaplan-Meier method.Aims
Patients and Methods
The aim of this study was to compare the biomechanical stability and clinical outcome of external fixator combined with limited internal fixation (EFLIF) and open reduction and internal fixation (ORIF) in treating Sanders type 2 calcaneal fractures. Two types of fixation systems were selected for finite element analysis and a dual cohort study. Two fixation systems were simulated to fix the fracture in a finite element model. The relative displacement and stress distribution were analysed and compared. A total of 71 consecutive patients with closed Sanders type 2 calcaneal fractures were enrolled and divided into two groups according to the treatment to which they chose: the EFLIF group and the ORIF group. The radiological and clinical outcomes were evaluated and compared.Objectives
Methods
To analyse the effectiveness of debridement and implant retention
(DAIR) in patients with hip periprosthetic joint infection (PJI)
and the relationship to patient characteristics. The outcome was
evaluated in hips with confirmed PJI and a follow-up of not less
than two years. Patients in whom DAIR was performed were identified from our
hip arthroplasty register (between 2004 and 2013). Adherence to
criteria for DAIR was assessed according to a previously published
algorithm.Aims
Patients and Methods
To determine the outcomes following revision surgery of metal-on-metal
hip arthroplasties (MoMHA) performed for adverse reactions to metal
debris (ARMD), and to identify factors predictive of re-revision. We performed a retrospective observational study using National
Joint Registry (NJR) data on 2535 MoMHAs undergoing revision surgery
for ARMD between 2008 and 2014. The outcomes studied following revision were
intra-operative complications, mortality and re-revision surgery.
Predictors of re-revision were identified using competing-risk regression
modelling.Aims
Patients and Methods
Myxofibrosarcomas (MFSs) are malignant soft-tissue sarcomas characteristically
presenting as painless slowly growing masses in the extremities.
Locally infiltrative growth means that the risk of local recurrence
is high. We reviewed our experience to make recommendations about
resection strategies and the role of the multidisciplinary team
in the management of these tumours. Patients with a primary or recurrent MFS who were treated surgically
in our unit between 1997 and 2012 were included in the study. Clinical
records and imaging were reviewed. A total of 50 patients with a
median age of 68.4 years (interquartile range 61.6 to 81.8) were
included. There were 35 men; 49 underwent surgery in our unit.Aims
Patients and Methods
Heterotopic ossification (HO) occurs after arthroplasty, especially
total hip arthroplasty. In this study we describe the incidence,
evolution, morphology and clinical consequences of HO following
reverse shoulder arthroplasty. This is a single-centre retrospective study of 132 consecutive
patients who received a Delta III or Delta Xtend reverse total shoulder
arthroplasty between 2006 and 2013 for the treatment of cuff tear
arthropathy. There were 96 women and 36 men. Their mean age at the
time of surgery was 69 years (49 to 89) and the mean follow-up was
36 months (12 to 84). The incidence, evolution, morphology and clinical
consequences of HO using the Constant-Murley score (CS) were analysed.
A modified Brooker classification of HO of the hip was used.Aims
Patients and Methods
Cubitus varus is the most common late complication of a supracondylar
fracture of the humerus in children. Correction can be performed
using one of a number of techniques of osteotomy but each has disadvantages.
We describe a new technique for correcting post-traumatic cubitus
varus using a lateral closing wedge isosceles triangular osteotomy. A lateral closing wedge isosceles triangular osteotomy was performed
in 25 patients (15 male and ten female with a mean age of 9.5 years
(6 to 12)) between May 2010 and April 2013. All patients had cubitus
varus secondary to malunion of a supracondylar fracture, with good
function of the elbow and a full range of movement. The osteotomy
lines were marked on the bone with an isosceles triangular template
made before surgery, after which the osteotomy was performed leaving
the medial cortex intact. Fixation was performed using two lateral
2 mm Kirschner (K)-wires and patients were immobilised in an above-elbow
plaster. By six to eight weeks callus was present and the wires
and cast were removed. Patients were reviewed at four and six weeks,
three, six and 12 months and then every two years until skeletal
maturity. Clinical and radiographic outcomes were categorised as excellent,
good or poor.Aims
Patients and Methods
The aim of this study was to report the outcome following primary
fixation or a staged protocol for type C fractures of the tibial
plafond. We studied all patients who sustained a complex intra-articular
fracture (AO type C) of the distal tibia over an 11-year period.
The primary short-term outcome was infection. The primary long-term
outcome was the Foot and Ankle Outcome Score (FAOS).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
