NASS guideline on cervical radiculopathy
The North American Spine Society (NASS) has released a new Evidence-Based Clinical Guideline regarding the diagnosis and treatment of cervical radiculopathy from degenerative disorders. The new guideline can serve as an educational tool to assist practitioners and provides a definition and explanation of the natural history of the condition, along with outlines for reasonable evaluation and treatment options.

Knee alignment and tibiofemoral OA
People with varus knee alignment may be at higher risk for tibiofemoral osteoarthritis (OA) compared to those with valgus alignment, according to an online study in Annals of the Rheumatic Diseases. The observational, longitudinal study of 2,702 participants from the Multicenter Osteoarthritis Study cohort found 950 patients (1,307 knees) with radiographic OA at baseline. Varus alignment was associated with a greater risk of medial osteoarthritis progression and a reduced risk of lateral progression, and valgus alignment was associated with a greater risk of lateral progression and a reduced risk of medial progression.
