The Denis Browne bar

The original, described in 1931, and the ancestor of every foot abduction brace in use today. In the one randomized trial against a newer design, it produced comparable results.

Written by Heath, who has lived it: casts from birth, a fusion at sixteen, the US Army, and distance running.

What it is

The design everything else is a variation on

Every foot abduction brace currently marketed is an evolution and adaptation of the orthosis Denis Browne described in 19311. The original is a dorsiflexed foot brace attached to leather boots, with openings at the toe and heel so the foot can be checked for being plantigrade1.

The bar is still the reference point. Markell shoes are designed specifically to work with a Denis Browne bar1, and when studies compare a new brace against “traditional” bracing, the Denis Browne is usually what they mean.

The basic arrangement, two shoes held on one bar, is simple enough to spot in an old family photo. The ones below are mine, from before the Ponseti method was standard, so the shoes and the schedule are not what a clinic hands out today.

Weigh the evidence yourself

Two studies disagree. Which would you trust more?

Pick one to see what it found, what it does well, and where it is weak. The third option is how the two read together.

The randomized trial

38 patients and 60 feet, randomly given either a Denis Browne or a newer above-knee brace, then followed for 24 months.

What it foundFinal Pirani scores were comparable, 0.42 against 0.57 (p = 0.411).

On compliance86.7 percent rated good or intermediate with the newer brace against 66.7 percent. Not statistically significant (p = 0.118).

Its strengthRandom allocation. Nobody chose which feet got which brace.

Its weaknessIt is small, and a trial this size can miss a real difference.

The retrospective series

28 patients and 49 feet, comparing a dynamic brace with a traditional Denis Browne after treatment had already happened.

What it foundNon-compliance of 41 percent with the Denis Browne against 7.1 percent with the dynamic brace, and skin lesions of 23.5 percent against 7 percent.

Its strengthA large gap that is easy to understand.

Its weaknessNo randomization. Families given a dynamic brace may differ in ways that also affect compliance.

AlsoCompliance in studies like this is usually reported by parents.

Read them together

They do not agree, and that is the honest state of the evidence. The stronger design found the feet came out the same. The weaker one found a large difference in whether families kept the brace on.

Both can be trueA brace can be harder to live with and still produce the same foot when it is actually worn.

What that means for youIf you have a Denis Browne and it stays on, the trial is the more relevant of the two.

If it does not stay onThe series is the one worth reading. What a dynamic bar changes.

The evidence

A randomized trial, which is rare here

Most brace comparisons are retrospective. One is not. A randomized controlled trial allocated 60 feet in 38 patients to either a foot external rotation above-knee brace or a Denis Browne, and followed them for 24 months2.

Final Pirani scores were comparable: 0.42 against 0.57, a difference that did not reach significance (p = 0.411). Parental compliance was better with the newer brace, 86.7 percent rated good or intermediate against 66.7 percent, but that difference also did not reach statistical significance (p = 0.118)2.

What it means. The authors concluded both braces achieved good comparable outcomes. On the thing that matters most, how the feet ended up, the ninety-year-old design held its own.

What it might mean. Thirty-eight patients is small, and a small trial can miss a real difference as easily as it can invent one. Neither result being significant means neither brace was shown to be better, which is not the same as showing they are the same.

Set against that, a separate series reported non-compliance of 41 percent with a traditional Denis Browne against 7.1 percent with a dynamic brace, and skin lesions of 23.5 percent against 7 percent1. That is a much larger gap than the trial found, from a weaker study design. Both things are in the literature and they do not agree.

What to make of it

Old is not the argument either way

The honest summary is that the case against the Denis Browne rests on comfort and compliance in retrospective series, and the one randomized comparison found the feet came out the same2.

Some authors have concluded that newer and more expensive designs did not deliver better compliance than the Denis Browne at all1. If you have been handed one, you have not been handed an inferior brace.

Denis Browne bar

What is the Denis Browne bar?

The original foot abduction orthosis, described in 1931. A dorsiflexed foot brace on leather boots, with openings at the toe and heel so the foot can be checked for being plantigrade. Every brace in use today is an adaptation of it.

Is the Denis Browne brace outdated?

Not on the evidence. A randomized trial of 60 feet found final Pirani scores comparable with a newer brace, 0.42 against 0.57, with no significant difference. It remains the design others are measured against.

Do newer braces have better compliance?

It depends which study. In the randomized trial the compliance difference was not statistically significant. In a retrospective series the gap was large: 41 percent non-compliance with a Denis Browne against 7.1 percent with a dynamic brace. The literature does not agree with itself here.

What shoes go with a Denis Browne bar?

Markell shoes are designed specifically for it. Other shoes attach to other bars, and compatibility is a question for the orthotist rather than something to arrange yourself.

Why is it still used?

It works, it is simple, and it is inexpensive relative to the newer designs. The trial evidence does not show a newer brace producing better-corrected feet.
