Examples And Differences Between Chronic and Acute Injury

Have you ever heard your doctor saying that your injury is an acute or chronic one? What are their differences? You need to know exactly what they are and what you should do. Their symptoms are different and the treatment methods differ as well. After all, it is your own body and you will be the one affected by it.

Acute injury

Acute injury is a sudden injury that is usually associated with a traumatic event such as clashing into another player during sports or a fall from a bike. You body undergo changes during this period and often it is a negative one. A traumatic impact can cause your bone to crack, muscles to tear or ligaments to snap. You will experience a sudden sharp pain that is often severe, immediate swelling and even cold purple regions in your body that indicates a lack of proper blood circulation in that injured part. You may even lose your stability if your knee ligaments are torn and you will be unable to place your body weight on it.

Chronic injury

Chronic injuries can be also called overuse injuries. Like the name suggests, it is caused by overuse of particular part of your body either through sports or exercises. They develop slowly and last a long time. Their symptoms are mild compared to acute injuries and the pain they cause are also little. This causes the patient to ignore the injury and carry on with their activities. Over time, it will build up and cause more problems. Some common symptoms of chronic injuries include experiencing pain whenever you engage in sporting activities, swelling after each game and constant aching when you are not doing anything. In other words, chronic injuries are lifestyle threatening as they restrict you from participating in many things. Some examples of chronic injuries are stress fractures caused by repeated loading of a particular part, causing tiny cracks in your bone each time. Tennis players also commonly suffer from tennis elbow which is effectively pain near the elbow due to overuse.

Whether the injury is chronic or acute, they must be treated immediately. The first step would be to stop whatever sporting activity immediately and perform R.I.C.E. Out of these 2 injuries, the most dangerous one would be chronic injuries as their pain is minimal but will last for a long time. Patients will thus be unable to know the full extent of their injury.

4 Steps To Reduce Risk of ACL Injury


There are 4 main ligaments in our knee which gives rise to the stability. The ligaments work together to prevent excessive motion to the knee joint and prevent over stretching which might lead to injuries. The most important ligament out of the 4 is the Anterior Cruciate Ligament (ACL). However, ACL injuries are also the most common ligament injury and many teenagers have had ACL reconstruction performed on them. So what are some steps you can take to help reduce the risk of ACL injury?

Before knowing how to reduce the risk of ACL injuries, you should understand how does the ACL tear. ACL tears occur due to a sudden twisting action, causing tremendous stress on the ligaments and ultimately rupturing the ACL. This is much more common in sports such as rugby, basketball and soccer which involves constant knee twisting and sudden changes in direction where the foot is still firmly rooted in the ground while the knee twists, instantly tearing the ACL.

Leg muscle strengthening

Leg muscle strengthening exercises will help to increase leg strength and lead to a more stable knee joint. A strong knee joint can help to resist sudden movement and hold the ligaments firmly in place during sudden twisting actions, reducing the risk of ACL injuries. Some excellent leg muscle strengthening exercises include hamstring curls, walking lunges and toe heel raises.

Neuromuscular training

Neuromuscular training is an excellent preventive method. It teaches the body how to obtain maximum knee stability and how the knee should move when jumping, pivoting and landing. Most injuries occur due to awkward landing on the knees, causing the ligament to twist and rupture. Scientific studies have also concluded that neuromuscular training significantly reduces the risk of ACL tears.

Knee bracing

If you have a weak knee or feel a little instability in the knee, you should use a knee brace. A good knee brace is able to make you feel like you are not wearing one, hold the knee ligaments firmly together and offer better support to the knee as a whole. There are some knee braces that are even allowed to be worn for games. Knee braces will offer better stability and provide you with more confidence.

Sufficient rest

Sufficient rest periods in-between training and games will allow the body ample of time for reconditioning and repair of the tissues. If you overstress your body, you are depriving it of repair time and sooner or later, the tissues and ligaments will break down. To speed up recovery process, some athletes consume foods that are high in protein such as chicken breast and protein shakes.

Reducing the risk of ACL injuries is as easy as 1-2-3. You only need to make a little bit of effort to buff up the muscles and don protective and supportive gears when you are playing your favourite sport.


3 Types of Anterior Shoulder Instability

Shoulder instability is a condition when the ball of the shoulder is dislocated from the socket, causing problems for people. The shoulder anatomy can be explained by using a ball and socket model. The ball is able to move about in the socket, providing nearly full range of motion for the shoulder. However, this model can cause instability when the ball slips out of the socket when injured. Anterior instability is caused by the ball slipping out from the front of the socket. Anterior instability is usually caused by trauma, with a sudden impact on the shoulder either directly or indirectly.

One of the most important structures that stabilize our shoulder is the inferior glenohumeral ligament, commonly known as IGHL. The IGHL limits gross anterior-inferior subluxations and prevents any sudden movement. During an anterior shoulder injury, the sudden huge impact normally exceeds the amount of force the ligaments can withstand, thus causing tears and stretching. This will in turn lead to instability of the shoulder.

When there is the presence of Bankart lesions repair, it implies that there is a failure of the IGHL at the gelnoid insertion. The most common lesion in anterior shoulder instability is the Bankart lesion. The tear is big enough to involve the labrum, the middle labrum as well as the superoanterior labrum. Without the labrum, the ball will get dislocated from the shoulder socket and causes subluxation. As the ball pops out of the socket, the labrum is often torn in the process. Patients suffering from a Bankart lesion will experience their scapular periosteum rupturing as theirlabroligamentous ligaments are forcefully detached from the glenoid.

3 types of instability are devised for medical practitioner to plan for bankart surgery:

  1. Type 1 – Presence of a partial Bankart lesion with a small detachment of the capsulolabral complex but no indication of the capsule stripping from the glenoid labrum
  2. Type 2 – Moderate detaching of the labrum and the capsule from the glenoid, with preservation of the labral shape.
  3. Type 3 – Severe detaching of the capsulolabral complex, with attenuation of the glenoid labrum

Our shoulders play an important role in our day to day activities. It is of utmost importance to protect it. Building strong shoulder muscles is the best defence against dislocations and instability. A delay in diagnosis may lead to more serious long term problems such as arthritis. Patients should seek immediate medical assistance prevent it from getting worse.
