Hao and their dedicated team for their hard work in making this Newsletter a success. Witheach edition, we have witnessed the evolution of our Newsletter, presenting a diverse rangeof content including scientific articles including rare case reports and groundbreaking original
research papers in the field of foot and ankle surgery.
I would like to congratulate Professor Jin Woo Lee on his great success of hosting 2024 IFFAS
meeting in Seoul. His great team has showed us what a successful academic meeting should
be! And I am also honoured to inform you that the upcoming 10th AFFAS meeting will be heldin Singapore in Oct. 2025. This meeting will be hosted by Dr. Keen Wai Chong. I want to thankDr. Chong for his effort in preparing this AFFAS meeting. This conference promises to be aremarkable gathering of distinguished foot and ankle surgeons from around the world. And it
will offer a unique platform for collaboration and the exchange of innovative ideas about footankle surgery. Please book mark this event in your schedule and encourage your colleague toattend this meeting.

Dear Colleagues,
It is with great honour that Singapore has been selected as the host country for the scientificmeeting of the 10th Asian Federation of Foot & Ankle Surgeons. It is also a great responsibility
to ensure that the meeting will live up to the high standards achieved by President Huang
Peng-Ju in the most recent 9th AFFAS in Kaohsiung.
After consultations with the AFFAS country councils during our recent council meeting inSeoul, it was decided that the best dates will be from October 30th to November 1st 2025. As
such, we have started preparations.
As I am also the President of the Singapore Orthopaedic Association in 2025, the 10th AFFAS
meeting in 2025 will be held in conjunction with the Singapore Orthopaedic Association 46th
Annual Scientific Meeting. The theme of the ASM will be on the Foot and Ankle. I have also
managed to obtain preliminary approval from AO Asia Pacific to hold a concurrent AO Trauma
Foot & Ankle Symposium. In addition, I also plan to have a pre-congress cadaveric workshop
in Foot & Ankle arthroscopy and sports medicine. All these events will be held in and around
October 30th to November 1st 2025. Please make a date on your calendars.
With the many academic activities, it is my hope that the 10th AFFAS will be well attended
and supported by all our Asian colleagues, from senior surgeons to residents. There will besomething for everyone.

Distal Metatarsal Osteotomies with the Spear Plate inAsian Patients for Hallux Valgus Correction
Zhi H Tang1, Keen W Chong2, Chi S Chong3
Received on:30 June 2023; Accepted on: 15 September 2023; Published on: 30 December 2023

The highlight of this paper is to introduce a minimally-invasive technique in hallux valgus correction
with the use of intramedullary plate fixation.
Percutaneous hallux valgus correction with screw fixation has gained popularity over recent years.
Stable fixation would depend on an “in-out-in” screw engaging the lateral cortex of the metatarsalbone. Placement of the screw can be technically demanding.
Use of intramedullary implant to stabilise the osteotomy in a minimally invasive fashion can be an
useful alternative, providing a stable construct.
In this paper, we report improvement in hallux valgus angle, inter-metatarsal angle as well tibial
sesamoid position in a series of Asian patients who had undergone hallux valgus correction using theSpear plate.

Validity of the Center-Center Method for the Syndesmotic
Fixation Axis Compared to the Transsyndesmotic Axis.

Placement of clamp forceps along the trans-syndesmotic axis reduces the risk of iatrogenic
syndesmotic malreduction during ankle fracture surgery with tibiofibular diastasis. However,determining the transsyndesmotic axis is challenging intraoperatively.
This study assessed the difference between the transsyndesmotic axis and the axis determinedby an intraoperative fluoroscopic center-center technique using digitally reconstructedradiographs. We found that the transsyndesmotic axis was externally rotated to the centercenter axis in the axial plane. We also found that the difference between the two axes wassmaller when the center-center technique was applied closer to the ankle joint. These findings
can assist surgeons in accurately placing syndesmotic clamping and subsequent fixation along
the transsyndesmotic axis for optimal results
