Professional activities during the trip from Sydney to Zurich:
In Hong Kong we visited Prof S.P. Chow and the Laboratories
of the Hong Kong University and of Queen Mary hospital and gave a presentation
on fracture treatment in porotic bone to AO alumni.The next day we visited
the laboratories and the teaching center of the Chinese University where
we participated in a series of lectures regarding the topic of osteoporosis
specially fall prevention treatment and fracture stabilization. The meetings
in Hong Kong were highly interesting, thank you S.P.Chow and P.C. Leung
and Qin Ling. Hope to see you soon again.

Med Activities in Japan
- Monday: Okinawa: technical stop for refueling and rest
- Tuesday: Arrival in Nagoya:and by Shinkansen to Kyoto to meet Prof.
Sadami Tsutsumi director of Material Research. Exchange about the different
running projects. One of the results of this discussion was the organization
of a meeting between Prof. Tsutsumi and the biomechanical research group
in Brisbane at the Queensland University of Technology (QUT). The topic
will be computer modeling of bone healing. An area of research where
Prof. Tsutsumi works with PC programs using parallel computing.
- Wednesday: Meeting with Prof. Shideo Niva in Nogoya. The main topic
of the discussion was fitness and senso motoric coordination. A topic
which is important in preventing, reducing squeal of fall and improving
the result of the internal stabilization of fractures in porotic bone.
The latter is achieved by improving control of loading of stabilized
- Thursday: Meeting with Prof. Moritoshi Itoman at Kitasato University
Tokio. Visit of the clinic, the bone bank and the research laboratories.
With Prof Ken Urabe the use of bone bank tendon was
the topic of discussion, the indication and problems of the Clancey
method, the autologous free graft and the bank graft of tendon with
bone to bone insertion. Prof. Kouji Naruse M.D. Ph.D., the head of the
research group, showed us his work on Low Intensity Pulsed Ultrasonic
Stimulation (LIPUS) of bone healing and treatment of delayed and non
unions. The animal model used is the rat remur fracture. The possibilities
and limitations of using this method together with implants was a topic
of interest. It would certainly be interesting to compare the results
of internal optimal internal fixation alone, internal fixation with
growth factors and internal fixation with LIPUS. The
internal fixator method for fractures or osteotomies in the mouse developed
in the Research Institute and Development Institute of Davos would offer
good standardization and extension of the study into knock out mice
for studies of the molecular biology aspects of fracture healing, treatment
and stimulation. In Tokyo we also met with Dr. Mat Yamage Ph.D. D.V.M.
who had worked earlier on in the Davos Research Lab studying the immunological
reaction of blood cells to metals. He since worked in Bern and at the
NIH and for the projects of the government in Kenya.
- Friday: By train to Kanazawa to meet Prof. Katsuro Tomita,
the pioneer of removal of vertebral bodies in tumors cases.
Here we also met with Prof. Takeshi Sawaguchi from Toyama. Prof. Sawaguchi
is member of newly created ASWG group under the chairmanship of Prof.
Michael Schütz. The goal of this group is to understand better
and allow reaction to the specific needs of the Asia orthopedic and
trauma world in respect to all aspects i.e. not only adapting the size
of the implants. A first meeting of the group had been held in Hong
Kong a few weeks ago. A meeting with local orthopaedic and trauma surgeons
followed in Kanazawa. The topic of discussion and presentation was fracture
fixation in osteoporotic bone. The different methods to improve anchorage
of implants, the biomechanics of the interface and the measures to protect
the interface from overload were discussed. The aspects of implant designs
and materials in relation to excessive locking of implants at screw
removal were discussed.
All in all the meetings in Japan were highly interesting and revealed
potential of collaboration. The meetings were in an excellent way organized
by Mr. Nobuo Fujii the manager for AO relations of Synthes Japan. Thanks
also to Mr. Kubota the head of Synthes Japan.
