The aim of this study was to examine the efficacy and safety
of multiple boluses of intravenous (IV) tranexamic acid (TXA) on
the hidden blood loss (HBL) and inflammatory response following
primary total hip arthroplasty (THA). A total of 150 patients were allocated randomly to receive a
single bolus of 20 mg/kg IV TXA before the incision (group A), a
single bolus followed by a second bolus of 1 g IV-TXA three hours
later (group B) or a single bolus followed by two boluses of 1 g
IV-TXA three and six hours later (group C). All patients were treated
using a standard peri-operative enhanced recovery protocol. Primary
outcomes were HBL and the level of haemoglobin (Hb) as well as the
levels of C-reactive protein (CRP) and interleukin-6 (IL-6) as markers
of inflammation. Secondary outcomes included the length of stay
in hospital and the incidence of venous thromboembolism (VTE).Aims
Patients and Methods
Infection following total hip or knee arthroplasty is a serious
complication. We noted an increase in post-operative infection in
cases carried out in temporary operating theatres. We therefore
compared those cases performed in standard and temporary operating
theatres and examined the deep periprosthetic infection rates. A total of 1223 primary hip and knee arthroplasties were performed
between August 2012 and June 2013. A total of 539 (44%) were performed
in temporary theatres. The two groups were matched for age, gender,
body mass index and American Society of Anesthesiologists grade.Aims
Patients and methods
The number of arthroplasties being performed
increases each year. Patients undergoing an arthroplasty are at
risk of venous thromboembolism (VTE) and appropriate prophylaxis
has been recommended. However, the optimal protocol and the best
agent to minimise VTE under these circumstances are not known. Although
many agents may be used, there is a difference in their efficacy
and the risk of bleeding. Thus, the selection of a particular agent relies
on the balance between the desire to minimise VTE and the attempt
to reduce the risk of bleeding, with its undesirable, and occasionally
fatal, consequences. Acetylsalicylic acid (aspirin) is an agent for VTE prophylaxis
following arthroplasty. Many studies have shown its efficacy in
minimising VTE under these circumstances. It is inexpensive and
well-tolerated, and its use does not require routine blood tests.
It is also a ‘milder’ agent and unlikely to result in haematoma
formation, which may increase both the risk of infection and the
need for further surgery. Aspirin is also unlikely to result in persistent
wound drainage, which has been shown to be associated with the use
of agents such as low-molecular-weight heparin (LMWH) and other
more aggressive agents. The main objective of this review was to summarise the current
evidence relating to the efficacy of aspirin as a VTE prophylaxis
following arthroplasty, and to address some of the common questions
about its use. There is convincing evidence that, taking all factors into account,
aspirin is an effective, inexpensive, and safe form of VTE following
arthroplasty in patients without a major risk factor for VTE, such
as previous VTE. Cite this article:
The purpose of the present study was to evaluate the impact of
intravenous tranexamic acid on the reduction of blood loss, transfusion
rate, and early post-operative clinical outcome in total shoulder
arthroplasty. A randomised, placebo-controlled trial which included 54 patients
undergoing unilateral primary stemless anatomical or stemmed reverse
total shoulder arthroplasty was undertaken. Patients received either
100 ml saline (placebo, n = 27), or 100 ml saline together with
1000 mg of tranexamic acid (TXA, n = 27) intravenously prior to
skin incision and during wound closure. Peri-operative blood loss
via an intra-articular drain was recorded and total blood loss was
calculated. The post-operative transfusion rate was documented.
Assessment of early clinical parameters included the visual analogue
scale for pain (VAS), documentation of haematoma formation and adverse events.Aims

Patients and Methods
Blood loss during total knee replacement (TKR)
remains a significant concern. In this study, 114 patients underwent TKR,
and were divided into two groups based on whether they received
a new generation fibrin sealant intra-operatively, or a local infiltration
containing adrenaline. Groups were then compared for mean calculated
total blood volume (TBV) loss, transfusion rates, and knee range
of movement. Mean TBV loss was similar between groups: fibrin sealant
mean was 705 ml (281 to 1744), local adrenaline mean was 712 ml
(261 to 2308) (p = 0.929). Overall, significantly fewer units of
blood were transfused in the fibrin sealant group (seven units)
compared with the local adrenaline group (15 units) (p = 0.0479).
Per patient transfused, significantly fewer units of blood were transfused
in the fibrin sealant group (1.0 units) compared with the local
adrenaline group (1.67 units) (p = 0.027), suggesting that the fibrin
sealant may reduce the need for multiple unit transfusions. Knee
range of movement was similar between groups. From our results,
it appears that application of this newer fibrin sealant results
in blood loss and transfusion rates that are low and similar to
previously applied fibrin sealants. Cite this article:
Lateral epicondylitis, or ’tennis elbow’, is
a common condition that usually affects patients between 35 and
55 years of age. It is generally self-limiting, but in some patients
it may continue to cause persistent symptoms, which can be refractory
to treatment. This review discusses the mechanism of disease, symptoms
and signs, investigations, current management protocols and potential
new treatments. Cite this article:
Induced membrane technique is a relatively new technique in the reconstruction of large bone defects. It involves the implantation of polymethylmethacrylate (PMMA) cement in the bone defects to induce the formation of membranes after radical debridement and reconstruction of bone defects using an autologous cancellous bone graft in a span of four to eight weeks. The purpose of this study was to explore the clinical outcomes of the induced membrane technique for the treatment of post-traumatic osteomyelitis in 32 patients. A total of 32 cases of post-traumatic osteomyelitis were admitted to our department between August 2011 and October 2012. This retrospective study included 22 men and ten women, with a mean age of 40 years (19 to 70). Within this group there were 20 tibias and 12 femurs with a mean defect of 5 cm (1.5 to 12.5). Antibiotic-loaded PMMA cement was inserted into the defects after radical debridement. After approximately eight weeks, the defects were implanted with bone graft.Objectives
Methods
An extensive review of the spinal and arthroplasty
literature was undertaken to evaluate the effectiveness of local
antibiotic irrigation during surgery. The efficacy of antibiotic
irrigation for the prevention of acute post-operative infection
after total joint arthroplasty was evaluated retrospectively in
2293 arthroplasties (1990 patients) between January 2004 and December
2013. The mean follow-up was 73 months (20 to 139). One surgeon
performed all the procedures with minimal post-operative infection. The intra-operative protocol included an irrigation solution
of normal saline with vancomycin 1000 mg/l and polymyxin 250 000
units/l at the rate of 2 l per hour. No patient required re-admission
for primary infection or further antibiotic treatment. Two morbidly obese
patients (two total hip arthroplasties) developed subcutaneous fat
necrosis requiring debridement and one was revised because the deep
capsular sutures were contaminated by the draining subcutaneous
haematoma. One patient who had undergone total knee arthroplasty
had unrecognised damage to the lateral superior geniculate artery
and developed a haematoma that became infected secondarily four
months after the surgery and underwent revision. The use of antibiotic irrigation during arthroplasty surgery
has been highly effective for the prevention of infection in the
author’s practice. However, it should be understood that any routine
prophylactic use of antibiotics may result in resistant organisms,
and the wise stewardship of the use of antibiotics is an important
part of surgical practice. Cite this article:

The long-term functional outcome of total hip arthroplasty (THA)
performed by trainees is not known. A multicentre retrospective
study of 879 THAs was undertaken to investigate any differences
in outcome between those performed by trainee surgeons and consultants. A total of 879 patients with a mean age of 69.5 years (37 to
94) were included in the study; 584 THAs (66.4%) were undertaken
by consultants, 138 (15.7%) by junior trainees and 148 (16.8%) by
senior trainees. Patients were scored using the Harris Hip Score
(HHS) pre-operatively and at one, three, five, seven and ten years
post-operatively. Surgical outcome, complications and survival were
compared between groups. The effect of supervision was determined
by comparing supervised and unsupervised trainees. A primary univariate
analysis was used to select variables for inclusion in multivariate
analysis. Aims
