Radiographic Evaluation of First Tarsometatarsal Joint Arthrodesis for Hallux Valgus Deformity: Does the Fusion of the First to the Second Metatarsal Base Reduce the Radiological Recurrence Rate?

Background: Modified Lapidus arthrodesis (MLA) is a well-established treatment option for symptomatic hallux valgus deformity (HVD). However, recurrence of the deformity remains a concern. The goal of this study was to evaluate the effect of an additional intermetatarsal fusion on the radiographic recurrence rate after first tarsometatarsal (TMT-I) arthrodesis.

A cone beam CT based 3D-assessment of bony forefoot geometry after modified Lapidus arthrodesis.

Background: Modified Lapidus arthrodesis (MLA) is a well-established treatment modality for hallux valgus deformities (HVD) associated with instability of the first ray. Although the three-dimensional (3D) nature of HVD has long been recognized, diagnostics still focus on plain radiographs. The objective of this study was to validate 3D Cone Beam CT (CBCT) in the perioperative assessment of HVD with focus on the alignment of the forefoot.

Pedographic, clinical, and functional outcome after scarf osteotomy.

The aim of this study was to investigate whether a Scarf osteotomy for hallux valgus correction achieves a good functional restoration with pain reduction, improved mobility, and hallux loading. Therefore, we prospectively studied 32 patients who had a Scarf osteotomy for unilateral hallux valgus. We performed clinical, radiographic, and pedographic evaluations after a mean followup of 33 months to assess clinical and functional outcomes.
