Extensive limb lengthening in Ollier's disease: 25-year follow-up.

A case of extensive lower limb lengthening (32 cm) in a 14-year-old male patient with Ollier's disease is reported. A varus deformity of the femur and a valgus deformity of the tibia were evident. The femur was successfully lengthened 22 cm by metaphyseal distraction, and the tibia was lengthened 10 cm by two-stage distraction-compression method with a cylindrical bone allograft.

Bone status in healthy Estonian women assessed with quantitative ultrasonometry.

We assessed age-related changes of bone status in healthy Estonian women in various age groups with quantitative ultrasonometry. The speed of sound (SOS), broadband ultrasound attenuation (BUA), and stiffness index (SI) of the calcaneus were measured in 288 women. BUA and SI values peaked at 30-39 years of age while SOS peaked at 20-29 years and decreased thereafter.
