BACKGROUND Metatarsus primus elevatus (MPE) has long been suggested as a primary causative factor in the pathogenesis of hallux rigidus (HR). The purpose of this investigation was to more clearly define this relationship by comparison of first ray position in patients with hallux rigidus, hallux valgus, and a control population with no known foot pathology. MATERIALS AND METHODS Clinical and ...

Recent molecular phylogenetic investigations of the red algal genus Mastocarpus from the northeast Pacific resolved numerous cryptic species. Although species were clearly defined through genetic analyses, the correct names to apply to the species remained unclear due to both morphological variability within species and morphological similarity between species. To determine the appropriate name...

An intra-articular ligament of the first metatarsophalangeal joint (MTPJ) has been observed by the authors during dissection for hallux valgus and hallux rigidus corrective surgery over a number of years. The enigmatic incidence and role of this structure prompted further investigation. A literature review was conducted across several scientific databases using the search terms “first metatarso...

This is a retrospective, multicenter study examining the long-term results for the treatment of end-stage hallux rigidus using 3 different surgical procedures. A total of 158 subjects (105 females and 53 males) were included in the present study. They had undergone 1 of the following surgical procedures: arthrodesis, hemi-implant, or resectional arthroplasty. The long-term results for the subje...
