Osteoarthritis of the trapezometacarpal joint is a common form of arthritis. At present, there is a significant void between conservative and operative managements. Viscosupplementation is occasionally considered as an in-between therapy.

We aimed to compare the therapeutic benefit of a single intra-articular injection of Sodium Hyaluronate (SH; OstenilĀ®mini) to a single intra-articular injection of Methylprednisolone Acetate (MA; Depomedrone) in the management of rhizarthrosis (TMOA; Trapezometacarpal Osteoarthritis).

A retrospective review was performed over a 12 month period. We reviewed 25 patients who had received a single injection of viscosupplementation (SH) performed with fluoroscopic guidance and had been followed up at 12 weeks. These patients were compared with 21 patients who had received a single steroid injection (MA) and had been followed up at 12 weeks.

Of the SH group, 52% (n = 13) reported some benefit from the injection. The MA group reported an 86% (n=18) benefit from the injection.

We found that a single injection of viscosupplementation (SH) is effective in relieving pain and improving function in about half of patients with rhizarthrosis (TMOA). The efficacy of a single steroid injection (MA), however, was superior with a far greater proportion of patients reporting analgesic and functional benefits.
