By Chris Faubel, MD -- Procedure description for intraarticular hip corticosteroid injection under fluoroscopy

By Chris Faubel, MD -- Kullenberg et al (2004) evaluated the effectiveness of intraarticular corticosteroid injections in eighty (80) patients with hip osteoarthritis and pain for more than 4 weeks. One group only received 2ml of Kenalog, while the other group received local anesthetic (mepivacaine) only. Intraarticular injections of local anesthetics are great for diagnosing whether "hip pain" is truly from the hip or not. But is it an effective pain reliever weeks later? Are corticosteroids more effective than local anesthetics for the hip? Do either decrease the incidence of total hip arthroplasty? Find out here.

The Roland-Morris Disability Questionnaire is an excellent, short, questionnaire for following the progress of patient's functional improvement with low back pain over time. It is particularly effective for acute and subacute patients.

By Chris Faubel, MD -- Anatomy Lesson: The PIN innervates all the muscles on the dorsal side of the forearm, EXCEPT the brachioradialis, extensor carpi radialis longus (ECRL), and anconeus.

By Chris Faubel, MD -- We know the high prevalence of lumbar spine pathology via MRI in asymptomatic individuals, but what about CAT scans?

By Chris Faubel, MD -- Borenstein et al. (2001) sent a questionnaire to 67 individuals whom obtained an MRI seven (7) years prior. The authors were trying to figure out if the painLESS pathology noted seven (7) years earlier, ended up becoming painFUL, and therefore predictive for future episodes of low back pain. They ultimately noted that the asymptomatic findings were NOT predictive of future development or duration of LBP.
