Background: Pes planus (flatfoot) and pes cavus (high arch foot) are common foot deformities, often requiring clinical and radiographic assessment for diagnosis and potential subsequent management. Traditional diagnostic methods, while effective, pose limitations such as cost, radiation exposure, and accessibility, particularly in underserved areas.
Aim: To develop deep learning algorithms that detect and classify such deformities using smartphone cameras.
Impact of dorsal closing wedge calcaneal osteotomy on hindfoot alignment and biomechanics of patients with insertional achilles tendinopathy; A weightbearing CT-based simulation study.

Article Synopsis
- The study investigates how dorsal closing wedge calcaneal osteotomy (DCWCO) influences hindfoot alignment and the power of the gastrocnemius-soleus (G-S) muscle complex in patients with insertional Achilles tendinopathy (IAT).
- Using CT scans of six patients, researchers created various foot models to analyze the biomechanics of different osteotomy placements (anterior vs. posterior) and resulted in 42-foot models.
- Findings suggest that the anterior osteotomy significantly impacts foot alignment and reduces the Böhler angle, while the posterior osteotomy leads to greater decompression of the Achilles tendon.
Current treatment strategy for managing Weber B ankle fractures is mainly governed by mortise congruency, malleolar alignment, deltoid ligament competence and fracture stability. While nonoperative treatment has yielded good functional outcomes in satisfactorily aligned stable injuries, a biomechanical rationale is not firmly established. Furthermore, current radiographic analysis is obscured by observer inaccuracy and beam rotation.

The talar dome is supplied by the posterior tibial artery (PTA) and, to a lesser degree, the sinus tarsi artery (STA). The role of talar dome hypovascularity on OLT remains poorly studied.
