iNTROdUcTiON

Orthopaedics and Trauma Queensland is an internationally recognised research group that

is developing into an international leader in research and education. it provides a stimulus

for research, education and clinical application within the international orthopaedic and

trauma communities.

Orthopaedics and Trauma Queensland develops and promotes the innovative use of

engineering and technology, in collaboration with surgeons, to provide new techniques,

materials, procedures and medical devices. its integration with clinical practice and strong links

with hospitals ensure that the research will be translated into practical outcomes for patients.

The group undertakes clinical practice in orthopaedics and trauma and applies core

engineering, modelling and clinical skills to challenges in medicine. The research is built on

a strong foundation of knowledge in biomedical engineering and incorporates expertise in

cell biology, mathematical modelling, human anatomy and physiology and clinical medicine

in orthopaedics and trauma. new knowledge is being developed and applied to the full

range of orthopaedic diseases and injuries, such as knee and hip replacements, fractures

and spinal deformities.

diREcTOR’s MEssAgE

welcome to the third Orthopaedics and Trauma Queensland

(O&TQ) annual report.

2008 was an exciting year with staff moving into the medical

engineering research Facility (merF) on the site of The Prince

charles hospital and the official opening on 16th september. merF

is already very busy running surgical skills workshops and the extra

research facilities are providing an impetus for accelerating research

activity in the group.

The research output of O&TQ continues to impress. in 2009 we are looking to develop our

international linkages and to investigate further funding avenues. in the first half of 2009

the group has continued to grow in numbers and research activity. Full details of these

activities will be provided in the 2009 annual report.

at the end of 2008 Professor dietmar w hutmacher took over as the medical device

domain leader in the institute of health and Biomedical innovation (ihBi), and associate

Professor clayton adam took over as the medical engineering Theme leader in the

Faculty of Built environment and engineering. These changes will provide us with a fresh

impetus to develop O&TQ into the future.

in addition, we have restructured O&TQ and i have pleasure in announcing that dr Peter

Boys, from the Queensland Orthopaedic research Trust has accepted the position of

chair of O&TQ. he will be leading our initiatives to position O&TQ both nationally and

internationally over the following year.

whilst i am standing down from some leadership positions i will still be intimately involved

in the activities of O&TQ. next year’s report will be led by Peter, clayton and dietmar and

i’m looking forward to the exciting prospects for the next few years.

Research and highlights

REsEARch OvERviEw

The research of Orthopaedics and Trauma

Queensland seeks to solve problems in a

broad range of areas, including:

sELEcTEd PROjEcT highLighTs

1. AO Brisbane spine Reference centre – Reducing secondary degeneration after spinal cord injury

The neurological damage from a spinal

cord injury is believed to be localised,

however it initiates a cascade of secondary

events which usually leads to extensive

and permanent paralysis. This secondary

damage begins with the disruption

of the blood – spinal cord barrier and

unleashes the body’s normal response

to tissue damage, inflammation. unlike

successful wound healing in other

tissues, inflammation in the spinal cord is

ongoing and can be observed for weeks

and months afterwards. This prolonged

inflammatory response is the catalyst for

secondary neurodegeneration and a major

reason for the limited repair response that

occurs naturally. in this ongoing work we

proposed that by early amplification of the

population and activation of inflammatory

cells, the inflammation would reach a

self limiting threshold and secondary

degeneration would not occur. we have now

shown that this is the case and Figure 1

below shows the difference between a

spinal cord where the inflammation has

been amplified (bottom) and one where it

has not (top). This work was recognised

by the spine society of australia research

award for 2008, and dr Ben goss was also

named runner up in the 2008 australian

society for medical research, Queensland

Premier’s award for senior Post-doctoral

medical researchers.

Figure 1. Images of two damaged spinal cords where the inflammation has been amplified (bottom) and one where it has not (top).

2. Medical Engineering – Probing the condition of cartilage during arthroscopy

a new quantitative arthroscopy system is

being developed to address the issues of

early stage detection of the causes of joint

degeneration and osteoarthritis in particular.

This device being developed by Professor

kunle Oloyede and Professor ross

crawford will be able to identify and

quantify the level of degradation of the

major components of articular cartilage.

The consequence of this capability will

be the elimination of subjectivity in the

visual assessment process which currently

limits the direct application of arthroscopic

evaluation to treatment.

The device will extend current grading

systems of the osteoarthritic condition to aid

treatment decisions, enabling the matching

of symptoms to surgical operations.

Furthermore, post-operative evaluation of

the healing process will be possible, leading

to the assessment of the effectiveness of

particular treatment methods.

Of significance is the inherent capacity of

this new device, the smarthroscope, to

categorise and quantify joint degeneration

in younger members of the population, so

that early intervention could be carried out.

The project will lead to potential reductions

in the need for extensive surgical

experience before effective diagnosis

and treatment decisions can be made.

Therefore the outcome will be beneficial to

regions of the world with limited surgical

expertise and facilities, such as developing

countries. more clinicians will be able

to participate in the treatment process

through quantitative diagnosis.

3. Northside spine Research group – Databases for clinical review of spine surgery procedures

The northside spine research group

is currently focused on developing

comprehensive clinical databases for a

range of spine surgery procedures to assess

the clinical efficacy of surgical treatments

for lumbar spinal disorders. Procedures

being assessed include: anterior lumbar

interbody fusion (aliF), transforaminal

lumbar interbody fusion (TliF), discectomy

(intervertebral disc removal), and

laminotomy/laminectomy procedures.

while the database development is

at an early stage, the potential for

improvement in clinical outcomes is

demonstrated in a current study of 78

patients undergoing spine fusion (TliF)

with a polyethylethylketone (Peek)

implant and bone morphogenetic protein

(BmP) to promote bony fusion. regular

post-operative assessment found early

complications in eight patients, two of

which were not linked with BmP. Fluid cyst

formation in the spinal canal in the region

of the posterior cage and the adjacent

epidural space were seen on post-operative

magnetic resonance imaging (mri) in four

patients. no such complications were seen

in 33 patients who previously underwent

TliF using a similar technique but where

bone graft rather than BmP was used.

Preliminary results indicate that, after a

change of BmP dose, fusion rates and

outcomes in these patients were improved.

The change in BmP dose and its effect on

bony union is being investigated over the

longer term by reviewing fusion rates pre

and post procedural change.

4. Orthopaedic Research group – Femoral nails for the developing world

whilst intramedullary nailing is a commonly

accepted technique for lower limb fracture

fixation, the cost of nails can be prohibitive

in hospitals in developing nations. in these

institutions bone cement has found many

‘off label’ applications, that whilst effective

do not meet manufacturer’s guidelines.

The aim of this study was to examine the

biomechanics of one such application,

fracture fixation using a bone cement

intramedullary nail.

The experiment involved creating a broken

femur then fixing the fracture using a nail

made from antibiotic simplex bone cement.

intramedullary nails made from bone cement

were able to provide sufficient promise in

this situation to warrant further investigation

for their applicability as a low cost alternative

for use in developing countries (Figure 2).

Figure 2. Example of fracture fixation using bone cement

5. Paediatric spine Research group – Patient specific computer modelling of spinal deformity surgery

researchers in the Paediatric spine

research group are using computer

modelling techniques to assist surgeons

in better predicting surgical outcomes for

scoliosis patients. The computer models

are developed using a patient’s computed

tomography (cT) scans and include

representations for the bone geometry and

spinal soft tissues as well as the devices

implanted by the surgeon. These devices

include metal rods which are attached

to the patient’s spine with screws and

tightened to correct the spinal deformity.

By simulating the forces applied to the

patient’s spine both during and after

surgery, it is possible to predict stresses

and strains in the implant and spinal tissue.

using this information, possible overload

of the spine and implant materials can

be predicted and thus, post-operative

complications (such as screw loosening

or tissue damage) can be avoided. By

predicting the outcomes of surgical

procedures in individual patients before

they are carried out, this will provide

surgeons with a pre-operative planning

tool to reduce surgical complications

and improve patient outcomes following

scoliosis surgery (Figure 3).

Figure 3. Full spine computer model of a scoliosis patient with surgical implant attached. Screws (green) are embedded in the spinal bones, called vertebrae (purple) and when attached to a rod (green), they reduce the curved deformity.

6. Regenerative Medicine group – Establishment of large preclinical animal models for critical sized bone defect healing

in collaboration with the Orthopaedic and

Trauma research groups, Professor dietmar

hutmacher’s regenerative medicine group

is combining basic science with advanced

surgical techniques, to develop innovative

and translational (from bench to bedside)

bone tissue engineering technologies for

treating segmental bone defects.

The reconstruction of large bone segments

(Figure 4) remains a significant clinical

problem. large bone defects occur

mainly as a result of extensive bone

loss due to pathological events such

as trauma, inflammation, and surgical

treatment of tumours. Present therapeutic

approaches include the application of

bone graft transplants (autograft, allograft,

xenograft), as well as implants made of

different synthetic and natural biomaterials.

however, no existing therapy has been

proven to be fully satisfactory.

R e s e a R C H a n d H i g H l i g H t s [ 3 ]

The area of bone tissue engineering (which

has its main focus on the development

of bioactive materials) offers significant

potential for bone defect reconstruction.

To tackle major bone tissue engineering

problems however, it is essential that

animal models, fixation devices, surgical

procedures and measurement methods

are standardized to allow the accumulation

of a reliable data pool as a base for further

research directions.

in order to study a tissue engineered

construct it is necessary to develop an

animal model which represents the clinical

situation as closely as possible. Based on a

recent review by the regenerative medicine

group (reichert Jc et al, 2009 Biomaterials

30:2149–2163), 7–9 year old sheep

are considered to be the most suitable

animals for use in an experimental model

of bone defect healing. in mature sheep,

bone consists principally of primary bone

structure in comparison with the largely

secondary, haversian bone composition of

humans. secondary osteonal remodelling

in sheep only takes place at an average

age of 7–9 years. Therefore, only older

sheep have a bone biology that is similar to

that in humans.

multidisciplinary approaches are essential

to realise the vision of treating large

segmental tibia defects by using novel

scaffolds in combination with either cells

or growth factors, and the regenerative

medicine group has assembled a team of

engineers, basic scientists and surgeons,

with the aim of allowing australia to

become a leading player in this exciting

and competitive field.

7. Trauma Research group – The influence of surgical approach on fracture healing outcomes

The Trauma research group has recently

completed an animal study in sheep to

determine whether the surgical approach

– the way in which a fixation implant is

applied to the fractured bone – has any

influence on the healing outcome of bone

fractures (Figure 5). minimally invasive

(so-called ‘keyhole’) surgery has become

a popular method to apply fracture fixation

plates, with fewer fractures treated by a

traditional open reduction internal fixation,

where the fracture site is exposed along

the entire length of the implanted fracture

fixation plate. however, while the newer

method offers obvious cosmetic (smaller

scars) and other potential advantages

(e.g. reduced infection risk), it comes at

the cost of increased exposure to x-ray

radiation and is generally more demanding

for the surgeon.

while the complete evaluation of the

experiments is still ongoing, initial results

indicate advantages for fractures treated in

a minimally invasive fashion. The minimally

invasive surgical approach resulted in less

damage to the soft tissues surrounding

the fracture. This was demonstrated by

analysis of clinical markers for muscle

injuries in the circulating blood. mechanical

testing of the healing bone, which is a

measure of healing outcome, showed an

earlier recovery of strength and stiffness

for the fractures treated with the minimally

invasive approach.

These first results demonstrate that

minimally invasive surgery for the internal

fixation of bone fractures, despite being

more demanding for the surgeon, leads

to outcomes that are comparable, if

not better, than those achieved using

traditional surgical methods. These results

have direct clinical implications and will

further aid the development of improved

surgical methods for the application of

fracture fixation implants.

QUT sMART TRAiN

The QuT smart Train set off from ipswich

in may 2008, to travel throughout the

state of Queensland for six weeks, with its

final week spent in Brisbane. all faculties

at QuT joined forces to create another

exciting and worthwhile experience for the

rural and regional communities around

Queensland. it is one of the state’s largest

community outreach programs, having

hosted over 90 000 visitors to date. One of

the four carriages featured O&TQ research

activities and games including ‘Professor

crawford’s bone quiz’, and an interactive

‘spine surgery game’ which both proved to

be extremely popular.

a smart Train event on the Toowoomba

platform was combined with the launch

of the mater children’s hospital annual

fundraiser, ‘5 k’s for kids’. The Paediatric

spine research group were featured on

the Toowoomba platform representing

the successful collaborative partnership

between mater clinicians and QuT
