OrthoHeal FlexiOH Short Leg

Because immobilising a leg slows venous return and raises clot risk in a way an arm device does not. Temporary cast immobilisation of a leg in adults is associated with a 2 to 3 per cent risk of deep vein thrombosis, with consequences running from long-term leg pain and swelling through pulmonary embolism to death. Over 70,000 people a year in the UK are treated with a leg cast or splint, so this is a volume problem rather than an edge case. NICE guideline NG89 recommends pharmacological thromboprophylaxis for temporary lower limb immobilisation where the VTE risk outweighs the bleeding risk, which in practice means a documented risk assessment at the point the device goes on.

The Royal College of Emergency Medicine set them and audits against them. First, every emergency department should operate a risk assessment tool compliant with NICE NG89 for ambulatory adults requiring leg immobilisation. Second, every patient discharged with a leg immobilisation device should routinely receive a patient information leaflet setting out the raised clot risk and the symptoms that warrant urgent attention. Third, any patient whose assessment indicates thromboprophylaxis should receive the first dose before leaving the department. Buying a leg immobiliser without those three in place buys the risk without the control.

In some patients, yes, which makes it the most commercially and clinically consequential question on this datasheet. Published emergency guidance states that where a patient is managed in a removable device, permitted to weight-bear, and carries no other VTE risk factors, chemical thromboprophylaxis is not required. Guidance also expresses a preference for removable devices over rigid non-removable immobilisation where the injury allows. The supplied sheet does not state whether this device is weight-bearing, partially weight-bearing or non-weight-bearing. Ask for that in writing, ask whether a sole or footplate is supplied or sold separately, and ask what load the shell is rated to take.

Not stated. Manufacturer photography appears to show a footplate or sole arrangement beneath the foot, but a photograph is not a bill of materials and a walking surface is exactly the kind of component sold separately. Establish whether a sole is included, whether it is integral or detachable, whether it is replaceable when worn, and what surfaces it is rated for. A patient issued a weight-bearing device without a usable walking surface will improvise one, and the improvisation is where the falls happen.

So they can be seen. Circulation, colour, capillary refill, swelling and sensation at the toes are the standard checks for a below-knee immobilisation, and leaving the digits outside the shell means those checks need nothing removed. It also means the patient and any community practitioner can look at them between appointments. Two practical points follow: exposed toes need protecting in cold weather and against knocks, and patient instructions should say explicitly what change in colour, swelling or sensation means seeking urgent review.

More than the letters suggest. Six codes have to cover foot length, ankle circumference and calf circumference simultaneously, and those three vary independently between people: a slim ankle with a heavy calf, or a long foot on a narrow leg, is common rather than exceptional. Request the measurement chart showing what each code assumes at all three points, then check it against a sample of your own patients. On a device that may be weight-bearing, a poor fit at the foot is not just uncomfortable, it changes how load passes through the shell.

The usual problem, amplified. Lower limb injuries swell substantially and resolve slowly, and the leg is dependent for most of the day. Too tight risks neurovascular compromise, compartment syndrome and pressure injury, and the lower leg is a recognised site for all three. Too loose lets the limb move inside the shell and, on a weight-bearing device, lets load pass through the wrong places. Ask how the device accommodates that change and whether the zip provides any adjustment, because a full-length zip on a cured shell may or may not offer any.

By the full-length zip, without a cast saw. On a lower limb device that matters more than usual: compartment syndrome of the leg is a surgical emergency, and the immobilisation must come off completely and immediately, including any padding, with the limb elevated to heart level. A zip running the front of the shin achieves that in seconds with no saw injury risk. Confirm that it runs freely after curing and that the full length opens, and make the method part of staff familiarisation and of the patient leaflet.

All three follow from a leg immobilisation and none appears on the datasheet, so the department has to supply them. A patient in a below-knee device has altered gait and balance regardless of weight-bearing status, which raises falls risk particularly in older patients and on stairs. Crutches or another walking aid usually need issuing and fitting alongside. And driving in a lower limb immobilisation raises questions of vehicle control and insurance validity that patients should be told to check with their insurer rather than assume. Build all three into the patient information issued with the device.

The open lattice leaves a substantial proportion of skin exposed and the material is described as washable, so washing and showering are part of intended use. For a below-knee device worn over several weeks this is a meaningful benefit, and it removes the plastic-bag routine that patients otherwise resort to. Obtain the manufacturer's guidance on drying and full immersion, establish whether a liner is used and how it behaves when wet, and be specific in patient instructions about drying between the toes and around the heel.

Request the position in writing. Lower limb immobilisation is high volume, so the difference between single patient use and reprocessing is a material line in an annual budget rather than a technicality. If single patient use, establish the per-episode cost and the disposal route. If reprocessable, expect a defined decontamination method, a cycle limit, and the zip and any sole to inspect as separate wearing components.

OrthoHeal is an Indian manufacturer, and the FlexiOH range is distributed through European medical retail channels, which implies CE marking for the variants sold there. No CE marking or UKCA position is evidenced on the supplied sheet for the Short Leg, and this page makes no such claim on its behalf. Request the declaration of conformity, certificate scope, instructions for use and current UKCA position from the seller at quotation, and treat all four as conditions of order. Device classification under the UK Medical Devices Regulations 2002 is confirmed against the declaration at order.
