Bisphosphonates Cut Skeletal Morbidity in Multiple Myeloma
THURSDAY, May 17 (HealthDay News) -- For patients with multiple myeloma, bisphosphonate treatment is associated with reduced pathological vertebral fractures, skeletal related events (SREs), and pain, but bisphosphonates do not appear to improve overall survival (OS), with the exception of zoledronate, which has been found to be superior to placebo and etidronate for improving OS, according to a review and meta-analysis published online May 16 in the The Cochrane Library.

Lowest Fused Vertebral Level Linked to Motion in Scoliosis
THURSDAY, May 10 (HealthDay News) -- For postoperative patients with adolescent idiopathic scoliosis (AIS), preservation of vertebral motion segments allows for greater distribution of functional motion, according to a study published in the May 1 issue of Spine.
Lack of Sleep Not Necessarily Detrimental to Surgical Skills
