Metatarsus primus varus. A statistical study

Metatarsus primus varus. A statistical study.

A survey of 6000 schoolchildren discovered 36 cases of unilateral and 60 cases of bilateral hallux valgus, defined as a metatarsophalangeal angle of more than 14.5 degrees, measured on standing radiographs. Metatarsus primus varus was found not only in the early stages of hallux valgus but in the unaffected feet of children with unilateral hallux valgus. Adduction of the first metatarsal is not...

Systematic revision of the trilobite genera Laudonia and Lochmanolenellus (Olenelloidea) from the lower Dyeran (Cambrian Series 2) of western Laurentia.

The olenelloid trilobite genus Laudonia Harrington, 1956 was thought to occur widely along the Cordilleran margin of Laurentia in lowermost Dyeran strata (Cambrian Series 2). However, supposed occurrences in the Rosella Formation (Cassiar Mountains, northern British Columbia), the Mural Formation (Cariboo Mountains, east-central British Columbia) and the Poleta Formation (Nevada)--re-examined, ...

Ball and socket ankle joint in metatarsus adductus varus. (S-shaped or serpentine foot).

Metatarsus adductus varus is characterised by fixed adduction and supination of the forefoot and valgus deformity of the heel. On weight-bearing this valgus becomes more pronounced, thus enabling the forefoot to pronate and increase its area of contact with the ground (Figs. 1 and 2). This rare and unyielding deformity of the forefoot and hindfoot must be clearly distinguished from the common m...
