The effects of inclusion of minimal-dose corticosteroid in autologous whole blood and dextrose injection for the treatment of lateral epicondylitis
Journal of back and musculoskeletal rehabilitation. 2021
BACKGOUND Lateral epicondylitis (LE) is one of the most common musculoskeletal disorders that causes pain. OBJECTIVES We evaluated the effect of the inclusion of a minimal dose of corticosteroid in a solution comprising autologous whole blood (AWB), 20% dextrose, and 2% lidocaine for treating LE. METHODS In this randomized prospective trial LE patients were allocated to the CS+ group (n= 70; solution comprising 1 mL AWB, 1 mL 20% dextrose, 0.4 mL 2% lidocaine, and 0.1 mL (0.4 mg) dexamethasone palmitate; injected into the common wrist extensor tendon) or the CS- group (n= 70; same solution as above but without dexamethasone palmitate). Five injections were administered at monthly intervals. At each visit, pain intensity was evaluated using the numeric rating scale (NRS), and grip strength was measured using a hand-grip dynamometer. RESULTS In the CS+ and CS- groups, 1 and 10 patients dropped out, respectively. In both groups, the NRS scores at each evaluation were significantly lower than the pretreatment scores. The NRS scores from pretreatment to the second and third visits were significantly lower in the CS+ group than those in the CS- group. However, at the fourth and fifth visits, and 6 months after the last injection (the sixth visit), the degree of pain reduction between the groups was not significantly different. Grip strength increased significantly over time in both groups. At each evaluation, grip strength was significantly higher than that at the pretreatment stage. However, the degree of increase was not significantly different between groups. CONCLUSIONS The inclusion of a minimal dose of corticosteroid in the AWB and 20% dextrose injection can reduce pain, especially during early treatment.
