Core application of plantar scanner in medical diagnosis
The plantar scanner provides a scientific basis for clinical diagnosis and treatment through high-precision 3D modeling technology. Its medical diagnosis application covers the following areas:
I. Screening for abnormal foot structure
1. Arch morphology analysis
Using laser or structured light scanning technology, the arch height, curvature and symmetry are accurately measured to identify structural abnormalities such as flat feet (arch index <0.21) and high arch feet (arch index >0.37), with an error of ≤±0.5mm.
2. Quantitative evaluation of deformity
The 3D model can calculate parameters such as calcaneal valgus angle and hallux valgus angle, assist in the diagnosis of diseases such as hallux valgus and hallux valgus, and generate a visual report to guide the formulation of correction plans.

II. Postoperative rehabilitation and efficacy evaluation
1. Postoperative mechanical reconstruction verification
Compare the preoperative and postoperative 3D models to quantitatively evaluate the morphological recovery effects of arch correction, calcaneal osteotomy and other surgeries, and monitor the bone alignment status.
2. Dynamic tracking of rehabilitation training
By scanning data in multiple periods, analyzing changes in plantar morphology and other factors, and evaluating the efficacy of orthopedic insoles or rehabilitation training on lower limb force adjustment .
IV. Monitoring of children’s foot development
Early warning of abnormalities
Using non-invasive scanning technology, regularly record the development curve of children’s arches (such as the average annual growth value of arch height from 3 to 12 years old), identify developmental delays or abnormal trends, and provide a window period for intervention treatment .
V. Biomechanical pathology research
Diagnosis of gait abnormalities
Combined with dynamic pressure maps (such as the peak heel impact force and forefoot propulsion force distribution during the gait cycle), analyze the pathological mechanisms associated with plantar pressure imbalance and knee pain, lumbar compensatory scoliosis, etc.
