Article Synopsis
- Platelet-rich plasma (PRP) is derived from a person's own blood and is thought to aid in the healing of injuries by concentrating platelets, growth factors, and cytokines through a centrifugation process.
- * The paper reviews existing clinical studies on PRP injections specifically targeting the lumbar spine to assess their effectiveness in treating lower back pain, a major cause of disability among patients.
- * Although many studies support the use of PRP in various lumbar injection techniques, some research indicates it may not significantly alleviate back pain, highlighting the need for more rigorous, well-designed clinical trials to determine its true efficacy.
Objective: To describe a new technique to perform an ultrasound-guided intra-articular injection of the trapeziometacarpal (TMC) joint.
Design: Ultrasound-guided injection of the TMC joint was completed on fresh frozen cadaver hand specimens using diatriazoate meglumine contrast. A fluoroscopic posteroanterior image of the TMC joint was then obtained to verify intra-articular placement of the contrast.
