Otto Bock Tübinger Hip Abduction Brace Orthosis

Tübingen Hip Abduction Orthosis 28L10:

• Based on the principle of the proven seated squat position with flexion in excess of 90 degrees and moderate abduction
• Reproducible hip flexion setting
• Individual flexion using beaded cords
• Adjustable abduction using spreader bar
• Individually adaptable
• Easy to apply

In a multi-center study conducted in 20 clinics in Austria, Switzerland and Germany, Tönnis (1999) carried out a comparison of all commonly used treatment methods. The results of the infant hips which were treated with only one orthosis were evaluated. Tönnis compared the improvement of the bony alpha-angle in the sonograph according to Graf, from the beginning to the end of treatment. 

The most favourable position for risk-free development of the hip joints is what Fettweis calls the seated squat position and which Salter calls the human position, in which the hip joints are bent in excess of 90 degrees and abducted by about 40 degrees. Orthoses which provide these conditions and which prevent uncontrolled abduction with a spreader bar achieve grade I (complete maturing with alpha angle 62 degrees as the lower boundary) in 98 percent to 99 percent of all cases analysed by Tönnis. The Tübingen hip abduction orthosis meets all of the above requirements fully.

Over 100 000 Tübingen hip abduction orthoses were used between 1987 and 2000, primarily in German-speaking regions. Not a single case of femoral head necrosis is known.
