Background: The tibio-calcaneal angle (TCA) does not measure individual forefoot contributions to the overall foot balance. Using standard radiographs we calculated the ideal hindfoot alignment based on ground reaction force (GRF), independently from the tibial axis.
Methods: Thirty-six patients (40ft.) were included. Mean age was 56. Weight bearing radiographs were taken. Calcaneal offsets were measured using tibio-calcaneal angles and GRF algorithms. Measurements were compared using the Bland-Altman method.
Findings: Both methods agreed (p>0.05) but individual discrepancies were found. Mean measured offsets were -11.5mm (SD: 10.2) using TCA and -8mm (SD: 9.3) using GRF. Mean bias between the methods was -0.88mm.
Interpretation: The GRF algorithm successfully measured hindfoot alignment. The absence of a previous gold standard and radiographic variability are a limit. The TCA underestimated calcaneal offset. Discrepancies showed that forefoot position data provided increased accuracy. This could be of particular relevance for surgical planning.

Background: The management of anterior colliculus fractures in combination with deltoid ligament injuries is a topic of debate, and there is a need to improve surgical outcomes. The purpose of the present study was to describe the application of a modified double-row suture bridge technique and evaluate its early clinical outcomes in the management of anterior colliculus fracture combined with deltoid ligament injury.
Methods: From 2020 to 2022, 12 patients with anterior colliculus fracture combined with deltoid ligament injury were treated using a modified double-row suture bridge technique.

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.
Different Positions of Weightbearing CT Images Can Influence the Hindfoot Alignment Evaluation Using 2-Dimensional Methodology.

Background: Three-dimensional weightbearing CT (WBCT) has been widely used to assess foot and ankle alignment. However, most current measurement methods are based on 2-dimensional concepts-distance, long axis, angulation, etc-and are sensitive to changes in orientation of the WBCT images. This study demonstrated how changes in positioning of the image can significantly influence the evaluation of hindfoot alignment.
