[Haemophilia and knee function: are there differences between haemophilic and healthy children?].

With early prophylactic treatment our haemophilic children grow up in good health. Nevertheless, we cannot prevent every bleeding. Those bleedings may be just subclinical but they could lead to overloading of the knee and more and more of the ankle joint in the long term.

Orthopaedic issues in sports for persons with haemophilia.

Persons with haemophilia should not feel limited in their ability to participate in sports. After consultation with a physician or other health-care provider and with a proper understanding of the risks involved and the strategies for managing these risks, patients with haemophilia can - and should - enjoy physical activities. We have analysed numerous reports of sports injury statistics and used them to rank a variety of sports according to their degree of injury risk.

[Ultrasound topometric measurements of thoracic kyphosis and lumbar lordosis in school children with normal and insufficient posture].

Aim: The posture of school children was examined in order to establish whether possible differences in clinically normal and insufficient posture can be detected by means of ultrasound topometry.

Method: 105 healthy school children (56 female, 49 male) with an average age of 8 years (+/- 0.9) were examined.

Intra-articular hyaluronic acid in the treatment of haemophilic arthropathy of the knee. Clinical, radiological and sonographical assessment.

Hyaluronic acid has been used successfully in the treatment of osteoarthritis since 1989. There is no experience in haemophiliacs in larger study groups. In a prospective study, 20 patients (21 knees) with haemophilic arthropathy of the knee received 20 mg hyaluronic acid by intra-articular injection for 5 consecutive weeks.

[Measurement of spinal anteflexion in school children by ultrasound topometry].

Aim: The anteflexion of the spine in normal schoolchildren was examined by 3D real-time ultrasound topometry to see if differences in the form of restrictions of anteflexion could be detected.

Methods: 102 schoolchildren at the age of 7 to 9 years volunteered to the study. We measured the spinal anteflexion by recording the row of the spines (C7-L5) in a maximally flexed position with a topometric digitiser.
