Solitary plasmacytoma of thoracic vertebra in a woman with Lynch syndrome: A case report.

Introduction: One of the major disabling health conditions among elderly is back pain due to degenerative diseases. Less than 1% of spine disorders are caused by malignancies. Among the rare primary vertebral neoplasms the multiple myeloma and the plasmacytoma account for 26% of these cases.

ACL graft migration under cyclic loading.

Elongation and migration of ACL grafts will lead to a deterioration of the initial stability of ACL reconstructions. The graft migration has been sparsely investigated independently from the elongation of the graft-fixation complex. The hypothesis of this investigation was that cyclic tensile loads cause a measurable migration of the grafts.

The effect of meniscus compression on the biomechanical properties of repaired meniscal lesions. Winner of the AGA-DonJoy Award 2003.

Introduction: The objective of the present study was to investigate the influence of meniscus compression, as it occurs with weight-bearing, on the biomechanical behavior of different repair types.

Materials And Methods: Young human meniscal tissue specimens were fitted with a single Bionx Arrow, a Innovasive Meniscal Screw, or a vertical suture (Ethibond 2-0) according to standard clinical practice. Test specimens then underwent repetitive loading with 10 N under 1 N pretension up to a maximum of 1182 cycles and were finally loaded to failure.
