Study Tests Unilateral Versus Bilateral Lumbar Fusion
MONDAY, April 9 (HealthDay News) -- For patients with degenerative lumbar diseases, the unilateral pedicle screw (PS) instrumented transforaminal lumbar interbody fusion (TLIF) procedure results in shorter operative time, less blood loss, and reduced implant costs compared with a bilateral PS instrumented TLIF procedure, according to research published in the March issue of The Spine Journal.
Targeted Exercise Relieves Sciatica Pain
MONDAY, April 9 (HealthDay News) -- Active conservative symptom-guided therapy for severe sciatica can safely reduce pain and improve neurological function at a rate that matches or surpasses outcomes from common higher-cost surgical interventions, according to a Danish study published in the April 1 issue of Spine.
Lumbar Spinal Stenosis Lowers Health-Related QoL
FRIDAY, April 6 (HealthDay News) -- Patients diagnosed with lumbar spinal stenosis (LSS) have a substantial burden of illness and reduced health-related quality of life (HRQL) compared to the general population, and their HRQL is compounded by associated comorbidities, according to a study published in the March issue of The Spinal Journal.
