Otto disease

Ot·to dis·ease

(ot'ō),
a disease characterized by an inward bulging of the acetabulum into the pelvic cavity, resulting in protrusion of the femoral head; found in association with arthritis of the hip joints, usually rheumatoid arthritis.

arthrogryposis multiplex congenita

A rare sporadic condition characterised by joint contractures, dislocations, rigid skeletal deformities (e.g., clubfoot or talipes equinovarus), skin atrophy and replacement of limb muscles with fibrous tissue. AMC is not a sui generis disease, but rather a descriptive term that signifies multiple congenital contractures. The aetiologies encompass both neurogenic and primary myopathic diseases, but most cases are not due to neuromuscular disease.
 
Pathogenesis
Uncertain; a common link may be intrauterine movement during a critical period of limb development.
 
Management
Arthrodesis.
