Sir,
I read this article with interest and I want to
congratulate the authors for carrying
out a randomised controlled trial comparing manipulation under anaesthesia
with hydrodilatation. I would like to raise a few points regarding
hydrodilatation as a treatment for adhesive capsulitis of shoulder.
I want to draw the authors' attention to their statement that “there is a
lack of evidence on how to treat frozen shoulder.” There have been few
randomised controlled trials in the past comparing different ways to treat
frozen shoulder. Buchbinder et al1 reported the results of their work. The authors demonstrated the efficacy of arthrographic distension with normal saline and corticosteroid
over placebo in patients with a painful stiff shoulder. Three other trials2-4
have compared distension with or without steroid with corticosteroid
alone. Two of these studies2,3 failed to show any benefit for distension
and corticosteroid over corticosteroid injection alone. Gam et al4
reported a significant improvement in range of motion and analgesic use in
the group treated with distension and steroid compared with steroid alone.
We are currently evaluating the results of repeat distension in adhesive
capsulitis patients. Early results are quite promising and seem to extend
the benefit.
Buchbinder and Green5 stated that the timing of joint distension in
treating patients with frozen shoulder may also influence outcome. Due to
pain in the early stages of the disorder patients may be unable to tolerate
distension, resulting in the injection of insufficient volume. The authors
suggested that distension may be more effective in the later phases.
