Vacuum suspension socket, for the firmest fit we make
Vacuum suspension holds the socket on with suction instead of a pin or strap, so the stump and socket move as one. Less movement means less rubbing, better control and a leg that feels lighter, and some systems actively draw air out as you walk.

In short
How does vacuum suspension work?
The short answer
In a vacuum socket, the air between the liner and the socket is pushed out through a one-way valve, so the socket is held on by negative pressure. Passive systems use a seal-in liner or a sealing sleeve with an expulsion valve. Elevated vacuum systems, such as the Ottobock Harmony or the Össur Unity, add a small pump that keeps drawing air out as you walk, which also helps keep the stump size steady through the day.
A below knee leg with vacuum suspension typically costs Rs 250,000 to 900,000 or more.
Is it right for you?
Who vacuum suspension suits
Usually a good fit if
- Active users who want the most secure, controlled fit
- Stumps whose size stays fairly steady through the day
- Users with rubbing or pistoning on other systems
- Users with stump-end discomfort from a pin
We may advise waiting, or something else, if
- Stumps that change size a lot, including early after surgery and some dialysis patients
- Users who cannot keep to a careful daily routine
- Skin problems on the stump that need treating first
- Tight budgets; a pin lock gives much of the benefit for less
Systems
Three ways to use vacuum
From a simple sealing sleeve to a pump that keeps working as you walk.
| System | How the seal works | Typical user | Indicative price of the leg |
|---|---|---|---|
| Sleeve with valve | An outer sleeve seals the top of the socket | Moderate activity | Rs 250,000 to 500,000 |
| Seal-in liner | Rings on the liner seal inside the socket | Active users | Rs 300,000 to 650,000 |
| Elevated vacuum | A pump keeps drawing air out | Very active users | Rs 600,000 to 900,000+ |

How vacuum holds a leg on
When you push the stump into the socket, the air beneath it escapes through a one-way valve. A seal, either rings on the liner or a sleeve over the top of the socket, stops air getting back in. As you lift the leg, the vacuum holds the socket to the liner. With an elevated vacuum pump, the air is drawn out continuously, making the hold even firmer.
Why less movement matters
Every millimetre the stump moves inside the socket means rubbing, lost energy and a leg that feels heavier than it is. With vacuum, the socket moves with the stump, so control is better, the leg feels lighter and many users have fewer skin problems. Users often say they feel the ground better through the leg.
Stump size: the key to success
A vacuum socket fits a stump of a particular size. If the stump swells or shrinks a lot during the day, the seal can be lost or the fit becomes too tight. That is why vacuum suits stumps that have settled, and why it is usually not the first choice soon after surgery. Elevated vacuum systems help here, because the continuous suction tends to keep the stump size steadier.
Daily routine and the heat
Keep the valve clean and free of sand, put the leg on carefully so the seal sits right, and check the valve before walking. Heavy sweating can affect the seal in summer; dry the liner at midday. If you feel the socket loosen or hear air, stop, press the valve and push the stump back in firmly. For wudu, the leg comes off quickly once the valve is released.
Travelling to us?
Coming to us for vacuum suspension from another city or country
Tell us your city or country and your travel dates when you call. We plan the visits as close together as the stump allows, so most patients can finish the casting, test socket and fitting in one stay, whether they come from Quetta or fly in from Dubai, with a shorter trip later for adjustments if needed.
Questions
Questions about the vacuum suspension socket
How does a vacuum socket stay on?
Air is pushed out through a one-way valve when you put the leg on, and the seal stops it coming back in, so suction holds the socket to the liner.
Is vacuum suspension worth the extra cost?
For active users with a fairly steady stump size, it gives the firmest, most controlled fit and often fewer skin problems. For others, a pin lock is simpler and costs less.
What if I lose the seal while walking?
You will feel the socket loosen or hear air. Stop, press the valve and push the stump back in firmly. If it keeps happening, the liner, sleeve or socket needs checking.
Can I use vacuum suspension soon after surgery?
Usually not, because the stump changes size too much early on. A temporary leg with socks is better until the stump has settled.
