Efficacy and safety of intra-articular botulinum toxin injection therapy for joint pain: A systematic review and meta-analysis.

Background: Studies conducted in various animal models of joint pain showed an anti-nociceptive effect of intra-articular botulinum toxin type A (BoNT-A). Randomized controlled trials (RCTs) in humans suggest a potential effect but results are disparate.

Objectives: To assess the efficacy and safety of intra-articular BoNT-A for the treatment of joint pain.

Bone Tissue in Magnetic Resonance Imaging: Contribution of New Zero Echo Time Sequences.

The introduction of new ultrashort and zero echo time (ZTE) sequences is revolutionizing magnetic resonance imaging (MRI) and optimizing patient management. These sequences acquire signals in tissues with very short T2: mineralized bone, cortical bone, and calcium deposits. They can be added to a classic MRI protocol.

Osteochondritis dissecans of the finger in a young climber. A case report.

We report the case of a 17-year-old climber presenting a rare case of osteochondritis dissecans of a proximal interphalangeal finger joint. A thorough bibliographic search confirmed the rarity of this pathology. The diagnosis and treatment choice are discussed in view of the literature findings.

Intra-articular botulinum toxin A injection for painful base-of-thumb osteoarthritis: a double-blind, randomised, controlled, phase 3 trial (RHIBOT).

Background: Intra-articular botulinum toxin A injection might have analgesic effects in patients with joint diseases. We aimed to compare the effects of intra-articular botulinum toxin A injection with those of intra-articular saline injection for patients with painful base-of-thumb osteoarthritis.

Methods: RHIBOT was a double-blind, randomised, controlled, phase 3 trial conducted at Cochin Hospital, Paris, France.
