Researchers drive standardization of the evaluation and treatment of adult spinal deformity (ASD). Belgian researchers have found that the level of the medial joint line is the key prerequisite for normal joint stability. Japan “beats” U.S. when it comes to the expense of adult spinal deformity surgery.

What percentage of your knee patients ‘look good, feel bad’? If its 18%, you’re typical. Why? One reason may be over reliance on neutral alignment. That heretical thought was forcefully and brilliantly raised in this remarkable debate between Chit Ranawat and Michael Dunbar. If ever there was a MUST READ debate, this is it.


21,000-Patient Mental Health Study; Predicting Knee Pain by Weight Lost; Long-Term Hip Arthroscopy Follow Up Study

New study finds possible association between mental health disorders and complications in patients with thoracolumbar, cervical spinal pathologies. Research from NYU Langone Health indicates that youth and amount of weight loss can predict pain reduction in knee OA. And younger female patients without labral repairs are more likely to require revision arthroscopy.

Study says overdosing on food with Advanced Glycation End Products (AGEs) negatively impacts bone quality. Traditional ‘red flags’ not so predictive of serious pathology as previously thought, says work from HSS and Emory. And low vitamin D in mothers could mean elevated kyphosis risk for offspring.


Pediatric Osteoporosis Linked to Anti-Inflammatory Meds?; Tool Identifies Risk for Dislocations After THA; Do Higher Volume Hospitals=Better Value in Hip, Knee Revision?

Left: Young mice, before puberty (2 weeks old), have many nestin-positive (green) mesenchymal stem cells (MSCs) in the primary spongiosa to maintain or build bone mass during bone elongation initiated by the growth plate above.

Long-term glucocorticoid therapy dangerous for adolescent bone health. Which THA patients may be at higher risk for an implant dislocation? Researchers at NYU Langone Health have some thoughts. And Rush researchers find that low volume hospitals had a higher mean hospital-specific charges for hip, knee revision.
