The son (Alexei) of the last Tsar (Nicholas II) of Russia was a hemophiliac.

Occurrence, etiology, classification of the disease The incidence is approx. We distinguish various disorders depending on the defect in the blood clotting system: ▬ Hemophilia A: This is the commonest form, an X-linked recessive condition (gene locus Xq28).

Only 5% of hemophiliacs are affected by the same as that of a degenerative arthritis. The radiological changes can be classified The clinical manifestations of hemophilia depend on as shown in ⊡ Table 4. The classification of the severity of hemophilia is presented in ⊡ Table 4. As a rule, spon- taneous hemorrhages occur only if the plasma level is less than 5%, while patients with a plasma level of under 1% are greatly at risk. The severest changes are observed in the knee and elbow, while the lesions in the ankle, which is likewise frequently affected, are less likely to result in such a rapid onset of osteoarthritis. In a severe case of hemophilia, a hemorrhage can occur in one of these joints even after ⊡ Fig. CT scan of the pelvis of a 20-year old male patient with a a minor trauma. The bloody effusion remains in the joint huge hemophilic pseudotumor and very rapidly leads to damage to the cartilage surface.

The location of the gene defect in this autosomal-dominant disorder is not known. Histological in- vestigations have shown an absence of normal cancellous bone formation in the metaphysis in metatropic dwarfism, resulting in impaired enchondral bone formation. In others, the trunk is normal in length while the extremities are shortened (⊡ Fig. However, scoliosis and kyphosis, develop at an early stage, there- by shortening the trunk as well, while the face appears normal. Atlantoaxial instability is occasionally present and can cause a tetraplegia.

Very premature osteoarthritis can occur as a result of the changes in the epiphyses. The orthopaedic treatment addresses the deformities in the joints and the kyphoscoliosis. The location of the gene defect in this autosomal- recessive disorder is not yet known. Two subtypes are distinguished: Type I is characterized by the spotty distri- bution of enchondral ossification in the epiphyseal plates, an irregular metaphyseal junction and islands of poorly mineralized cartilage in the metaphyses.
