1. In unreduced congenital dislocation of the hip in adults, causing severe symptoms, it seems that there is a place for a calculated abduction type of femoral osteotomy, which should "defunction" a painful false joint. Care should be taken to avoid excessive angulation, which may lead to painful symptoms from contact of the osteotomy apex to the area of the true acetabulum. Genu valgum and lateral rotation deformity are complications, as is failure of union at the osteotomy site.

2. A series of eleven hips in seven patients is reported, in which such an abduction type of osteotomy has been done. Six of these hips have been highly satisfactory. Three have required subsequent operations to correct deformity. Only one has ended up with arthrodesis. In three, results have been only fair. The use of a reversed nail-plate to secure internal fixation is described.

1. A group of cases is presented in which the os intermetatarseum took the form of an intermetatarsal spur, from which (in members of one family) there arose a tendon-like structure whose distal attachment was to the lateral aspect of the proximal phalanx of the great toe. The suggestion is made that this may represent a lost first plantar interosseous muscle.

2. Another effect of the presence of an os intermetatarseum is the production of metatarsus primus varus by its action as a wedge which spreads apart the bases of the two metatarsal bones. A very small wedge may at times produce considerable deviation (Case 4), and resection of the os can result in satisfactory correction.

3. It is also felt that over-development of extensor hallucis brevis may at times contribute to the formation of hallux valgus.
