Biomechanical performance of the new BeadEx implant in the treatment of osteoporotic vertebral body compression fractures: restoration and maintenance of height and stability.

Background: Vertebral compression fractures are counted among the most common complications of osteoporosis. For treatment, a new, alternative implant has been developed (BeadEx, Expandis, Hof HaCarmel, Israel). The aim of the present in vitro study was to evaluate whether this implant is able to restore the initial height and three-dimensional stability after fracture and whether it is able to maintain this height and stability during complex cyclic loading.

[Asymptomatic bilateral developmental dislocation of the hip].

Developmental dislocation of the hip (DDH) is 1 of the commonest problems of the infant locomotive system. While its natural history is usually unpredictable, it is fully agreed that early diagnosis and treatment are essential. We present an 86-year-old man in whom asymptomatic bilateral DDH was diagnosed incidentally.
