Introduction

The exact statistics of ankle injury are difficult to get, but it is estimated that of all the trauma cases, about 10 per cent in general hospitals are related to the ankle. There is another interesting estimate that says 2.21 per 1000 exposure hours in youth (13-18 years) sports lead to ankle injury, largely in football. The injuries are of two types – sprain and broken. There are types in each case. Let us look them up by categories.

What is a sprained ankle?

A sprained ankle is basically a ligament tear. A ligament is a tissue or an elastic band-like thing that attaches two bones. An ankle has four such kinds of ligaments. The most common tear that happens is called the Anterior Talofibular Ligament (ATFL). This usually happens when one twists the ankle while walking on an uneven surface or when the foot falls in a hole, or something, and the foot turns inwards. When the foot turns inwards, the ligament on the outer side gets overstretched and tears, of course, on the application of a certain amount of force.

Ligament damage (the "rubber bands" connecting bones). Three grades: Grade 1 (stretch), Grade 2 (partial tear), Grade 3 (complete tear).

What is a broken ankle?

A broken ankle happens again with a similar kind of force or injury, but where instead of the ligament giving way, the bone fractures.

Break vs Sprain Ankle

The basic difference between a sprained ankle vs a broken ankle is that a sprained ankle is a soft tissue injury where the ligaments are affected, and a broken ankle is a bone injury where the two main bones called the fibula and the medial malleolus are fractured. The third part of the bone is called the posterior malleolus.

When it is only the fibula it is called a lateral malleolus fracture, when both the lateral and medial malleolus are involved it is called a bimalleolar fracture; and when all three are involved it is called a trimalleolar fracture.  

Shared symptoms (why it's confusing)

The symptoms are slightly confusing in minimally or undisplaced fractures when compared with sprained ankle, because they manifest themselves through the same swelling or redness on the lateral side or the outer side of the foot.

In cases where both the lateral and medial malleolus are fractured, then the patient is usually unable to bear weight. He cannot stand, unlike in a sprained ankle where he can stand but feels pain on certain movements.

Signs more likely in a sprain

Small swelling on the outer aspect of the foot. Patients can walk, they can put weight on their foot, but inward movement, or excessive inward movement, causes pain.

Signs more likely in a fracture:

Immediate severe pain, rapid swelling, deformity/visible misalignment, numbness/tingling, bone tenderness directly over the bone (not soft tissue), inability to bear any weight, audible crack sound

In fractures, if it is displaced, patients will also have problems standing. They will face an inability to put weight on their foot.

As in a sprain, even without a major immobilisation, the pain may gradually subside, but with a fracture the pain will increase if it is not treated.

The 4-Question Self-Assessment: Sprain or Break?

• Q1: Did you hear a sound? (pop = possible sprain; crack/grinding = more likely fracture)
• Q2: Where is the pain/tenderness? (over the bone = fracture signal; soft tissue = sprain signal)
• Q3: Is the ankle visibly deformed or crooked?
• Q4: Can you take 4 steps (Ottawa Ankle Rules)? - name and explain this clinical protocol; no competitor explains it in plain English

A sprain usually does not cause a sound or anything, though there is pain and tenderness or a sudden swelling. Usually there is no Ecchymosis (bleeding or internal haemorrhage).

The best thing to do after an injury is to apply ice and keep the limb elevated on a pillow or something similar, and then gradually exercise it. Immobilisation is prescribed if it is persistent. Fractures have to be obviously treated differently.

How Doctors Tell the Difference

Doctors identify by physical examination to see whether it is bony tenderness or a tender area over the bone, by which it is understood whether there is a higher chance of a fracture. There are certain soft points where the ligament tenderness is felt.

In either case. the protocol is to immobilise it first. Usually people tend to miss the ankle sprains because they tend to ignore it and often, as it is not immobilised, it becomes chronic later on. Ligament injuries are comparatively difficult to heal as opposed to bone injuries.

A bone is the only tissue the body which heals by forming new bone. All other tissues heal by forming scar tissue. So even when a ligament heals it is healed by a fibrous protein called collagen which may not have the properties of the original ligament. But a bone, once it is united is perfect

Treatment: Sprain vs Fracture - What's Different

Treating an ankle sprain/ We usually prescribe immobilisation of two to three weeks with a plaster shoe or an air cast walker or both. If it is a very minimal tenderness, then just a compression bandage.

Treating a broken ankle:

• Non-displaced: boot or cast (6–8 weeks).
• Displaced: surgical realignment + plate/screws (ORIF).

For fractures, the lateral malleolus fracture in isolation may be treated in a plaster. But the medial malleolus fracture, also known as a fracture of necessity, should be operated upon and fixed, as otherwise it will go on to become a non-union. There is a tissue called periosteum that goes inside the fracture site and does not allow new bones to form.  That’s why this requires surgical intervention.

Recovery Timeline:

• A sprain usually takes two to three weeks.
• Fractures usually take three months.

The difference in the recovery timeline is because, in surgery, a plate is screwed in to align the fractured bones, to allow the body to take care of the healing. For the bones to join, the body has to step in; a plate is not a bone substitute. It is just there to help the bone to unite in the proper axis and alignment and length over a period of three to six and nine months.

The newer plates that have come in are very thin, titanium, MRI-compatible, biologically inert, and not causing any allergic reactions are not usually removed these days. Only the syndesmotic screw needs removal.

Can You Have Both at the Same Time?

Yes, both can happen: a fracture on one side and a ligament tear on the other. For example, there can be a fracture on the lateral side and a deltoid ligament injury on the medial side.

Prevention: How to Protect Your Ankle

• Proper footwear for activity type
• Proprioception/balance exercises (proven to reduce re-sprain risk)
• Ankle taping/bracing for high-risk sports
• Strengthening: calf raises, lateral band walks, single-leg balance
• Warm-up before activity, avoid uneven surfaces when fatigued

However, a chronic ligament tear has to be operated upon with ligament reconstruction. Usually it is preserved for athletes or sportspersons or high activity individuals who suffer from chronic instability – episodes every three or four months where the leg is twisted, leading to pain for three to four days after which they are back to the field again. These types of people are operated upon with internal braces and ATFL (anterior talofibular ligament) repair.

What to Know About Your Ankle Injury

Conclusion

If your ankle is hurt, it is always advisable to seek appropriate medical advice by visiting a hospital. In a place like Peerless Hospital of the Peerless Group, there will be facilities to check your injury to determine appropriate treatment.  It is important to keep in mind that even a ligament tear needs properly guided care lest it become permanent. And if it is a fracture, only in a place like the Peerless Hospital can you receive the entire treatment procedure under one roof.
