Virtual Surgical Simulation & 3D Printed Surgical Guide forSupramalleolar Osteotomy Correction of Varus Deformity

JuVolume 3,

Case Presentation
Korea University Ansan Hospital
Gi Won Choi, M.D., Ph.D.
Best Academic Case Presentation Award, KFAS 2023 Spring Meeting
A 74-year-old female patient, who underwent surgery for a left tibial fracture 40 years ago,
visited the hospital with ankle varus deformity due to malunion (Fig 1). The patient complainedof discomfort while walking due to ankle and hindfoot varus deformity but did not complain ofankle pain. Therefore, correction using SMO was planned, and through visual surgical simulation,
it was predicted that a correction angle of 24 º and an osteotomy gap open of 12 mm would benecessary (Fig 2). An osteotomy guide (Fig 3) and an osteotomy gap block (Fig 4) were madeby 3D printing to perform the osteotomy and correct the deformity according to the predictedgoal. One year after surgery, ankle varus was corrected according to surgical simulation (Fig 5),
and the patient was able to walk comfortably. When the osteotomy for deformity correction wasperformed, virtual surgical simulation and 3D printed surgical guide can be used to predict thetarget value for correction and are useful for increasing the accuracy of deformity correction.

Use of HyProCure in Correcting Flatfoot in Adolescent andAdult Asians: A Radiographic Study Using a New Method ofMeasuring Hindfoot Alignment

The highlight of this paper is to introduce a new method of measuring hindfoot malalignment,
especially valgus malalignment.
Most of us are familiar with the Saltzman view for assessing hindfoot malalignment. However,the Saltzman view is not reproducible because it does not control the rotation of the ankle
i.e., if the ankle is in internal or external rotation, the hindfoot valgus measurement seen on
the Saltzman view can change. Some radiographers will use the medial border of the foot todetermine the ankle rotation; however, in many people with flatfoot deformity the forefoot isabducted. Aligning the medial border of the foot to face medially will result in the ankle being inexcessive internal rotation, hence affecting the eventual measurement of hindfoot valgus fromthe Saltzman view.
The method of measurement described here is named the Fibula Axis Calcaneal Offset
method (FACO). This is described in the paper in detail. In the study, this method is used toevaluate a series of patients who underwent flatfoot correction surgery to show how the FACO
measurements correlate with the flatfoot / heel valgus correction pre- and post-surgery. The
FACO method allows the radiographer to set the ankle in the correct rotation before performing
the X-ray. It does not require special equipment or X-ray platforms as it merely utilizes a standard
standing ankle mortise view for measurement. A standard standing ankle mortise view also
allows the patient to bear weight in a normal physiological condition.
In this paper, a series of adult and adolescent patients underwent peri-talar stabilization with asinus tarsi arthroereisis device. Their pre- and post-surgery hindfoot alignment, FACO, Meary'sangle and other radiographic parameters were measured. The aim of the paper is to showthat there is a significant and predictable improvement of the hindfoot valgus after peri-talar
stabilization and this can be measured objectively and accurately with the FACO method.
