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.

Protrusio acetabuli should be recognized prior to hip replacement surgery as this helps avoid potential complications.
Protrusio acetabuli is medial displacement of the acetabulum beyond the radiographic teardrop with medial migration of the femoral head into the pelvis (1).
Diagnosis of protrusio acetabuli is made on the basis of an antero-posterior radiograph of the pelvis that demonstrates a centre-edge angle greater than 40 degrees and medialization of the medial wall of the acetabulum past the ilioischial line (4).
Protrusio acetabuli and its potential complications should be recognised pre-operatively and this surgery should be regarded as a complex primary hip arthroplasty ideally performed by an experienced hip surgeon.
Abnormalities that can be associated with pincer FAI include acetabular retroversion, coxa profunda, and protrusio acetabuli.
Protrusio acetabuli and acetabular retroversion (a posteriorly oriented acetabulum) can be seen on oblique axial MRI of the hip.
Protrusio acetabuli, although not specific to PsA, is often found in patients with true PsA (Fig.
2) Protrusio acetabuli received scant attention until the turn of 19th century.
Primary protrusio acetabuli remains a diagnosis of exclusion, and as such many of the cases reported in the past may have in fact been secondary to undiagnosed conditions.
The incidence of primary protrusio acetabuli in these groups was 25.
Typically, patients with primary protrusio acetabuli present with increasing stiffness rather than pain.
Sherlock, (36) in 1995, suggested that primary protrusio acetabuli and acute idiopathic chondrolysis may have been the same condition.
