Understanding Injuries Related to Sport
Dr Joe de Beer has worked with many sportsmen over many different sports. Hes knowledge within sports injuries is diverse, listed below is some of the information he has acquired over his career.
Injuries Related to Cricket
Shoulder injuries can occur from direct falls onto the shoulder or indirect forces where the arm is outstretched and causes an injury to the shoulder- the force is applied to the lever of the arm which injures the pivot (the shoulder joint).
The diagnosis of the cause of shoulder pain can be made easier by taking into account certain principles. The age and gender of the person experiencing the pain, certain types of shoulder pain and disorders occur with frequency in certain ages and genders – commonly these conditions should be considered in such a person.
Rollover the yellow dots below depicting the possible injury areas and injuries within cricket.
As in rugby and soccer, concussion can occur. Symptoms include amnesia, memory loss, headache, confusion, poor coordination or vision difficulties. Players who have suffered concussions do not necessarily lose consciousness.
Little can actually be done to treat a concussion, other than rest. However, it's crucial that a physician examine anyone who might have a concussion in order to exclude intracranial bleeding.
The first type is an overuse injury of the shoulder associated with throwing, typically referred to as “thrower's shoulder”. The second type refers to acute, traumatic injuries,that are especially prevalent when players fall on a shoulder while they are fielding.
Thrower's shoulder is a chronic shoulder pain that gradually worsens while the player is throwing the ball.
There are a number of potential causes: Poor throwing technique, Shoulder muscle imbalance, Previous injury, Shoulder instability, Too much or too little practice, Poor posture.
Thrower's shoulder involves injury to the tendons of the rotator cuff (the muscles around the shoulder joint), and may include weakness around the scapula (shoulder blade). There may be associated bursitis (inflammation of the joint sac) within the shoulder.
Traumatic injury to the shoulder classically occur when a fielder dives for the ball and lands hard on an outstretched arm. The injury could include damage in the form of tears to the tendons around the shoulder and in isolated cases dislocation of the shoulder may occur. Pain in this kind of injury usually limits participation in the game.
Management of these injuries are listed below.

Improper batting and bowling techniques as well as incorrect equipment, such as bats that are too heavy, put unnecessary strain on the forearm.
Common types of injury include:
Tennis elbow is localised to the outside of the elbow. It can occur as a result of throwing, especially if the cricketer leads the throwing motion with his elbow.
Another possible cause of elbow pain would be a batsman attempting to use the wrist to flick the bat.
The pain is localized to the elbow and is aggravated by wrist and finger movements (such as shaking someone’s hand).
This injury is managed using physiotherapy and rehabilitation to correct strength imbalances of the forearm. It is important that the throwing and batting technique is assessed to identify risk factors for this injury.
Although not as common as tennis elbow, thrower’s elbow is just as debilitating and painful. Thrower’s elbow effects both the inside and outside of the elbow.
It is an overuse injury due to the extremely high forces on the elbow joint when throwing a ball. The throwing motion causes the structures on the medial side (inside) of the elbow to stretch, while at the same time compresses the structures on the lateral side (outside) of the elbow. Over time this results in micro fractures in the forearm bones and can eventually lead to bone spurs and bone chips.
Lower back pain is not a problem exclusive to the fast bowlers and is equally devastating when it happens to batsmen or wicketkeepers.
There are many potential causes of these injuries. Poor bowling technique (called a mixed action technique), overbowling and relative youth are the common culprits. Other possible causes include poor physical preparation, the impact forces associated with the delivery stride, inadequate footwear, and previous injury.
Early detection and diagnosis is very important. Following this, treatment includes physiotherapy for pain and rehabilitation, which is undertaken by a physiotherapist and biokineticist.
The focus of the rehabilitation is twofold:
Firstly, it is essential to retrain the core muscles which are responsible for spinal stability.
Secondly, and equally as important, is strengthening of the entire trunk, upper and lower body in order to help the body deal with the huge impact forces associated with fast bowling.
Biomechanical changes are often necessary and these can be achieved by means of collaboration between the medical team and the coach.
However, the injury might also include rib contusions, rib fractures, costochondral (the small joints between the sternum and ribs) separation and dislocation, sternum fracture and even an injury of the lungs.
In rare cases, damage to the internal organs such as the kidney, liver or spleen may occur.
A groin strain is a stretch, tear or the complete rupture of the muscle called the adductor longus, which runs from the pubic bone to the inside of the thigh bone. Groin strains will reoccur often if they are not allowed to heal fully.
Needless to say, getting hit by the ball in the groin is – very – painful and may result in testicular rupture. Wearing a cricket box, also known as a cup, is essential.
The most obvious area where injuries occur is at the striker’s end where finger/hand injuries are caused by the tremendous impact of the ball.
The hand consists of eight wrist bones, the palm with its five metacarpal bones, and the fingers. Treatment of finger fractures differ. Such fractures are generally treated by means of a so-called buddy strap by which the injured finger is attached to the adjacent finger. Any fracture takes six weeks to heal completely.
It is important that the finger is X-rayed to ensure that the fracture does not include a piece of bone that is displaced and will hamper the appropriate healing of the bone.
Management includes strapping the finger to provide support by splinting it to the adjacent finger.
In a limited number of cases surgery may be required. Physiotherapy is important to ensure that the finger and hand do not become stiff during the period of healing.
This can be a very frustrating injury as it can keep a cricketer out of the game for a number of weeks.
A muscle strain occurs when a muscle is loaded and a number of the muscle fibres become torn and inflammation of the tissue occurs.
A chronic hamstring tear is an injury common to many sports. Cricket is no different.
There are numerous risk factors for developing this injury, the most likely being a previous injury to the hamstring muscle. This is a very important point as it emphasizes the importance of rehabilitating the hamstring muscle adequately when it is first injured, to prevent recurrence.
Other factors which could cause a chronic hamstring strain would be muscle imbalance, lower back inflexibility or pain, inappropriate training, and slipping while batting or bowling.
A chronic hamstring strain can also involve an underlying ‘nerve problem’ and should be assessed by a physiotherapist.
An acute hamstring strain is associated with an acute overload of the muscle, which could occur during batting or fielding in a pressure situation.

Pain underneath the kneecap
Aching and stiffness after exertion
Pain when you contract your quadriceps
There are three grades of injury:
Grade one jumper’s knee is when the pain only occurs after training .
What can be done?
You can carry on training but always apply ice afterwards
Wear a support brace or a heat retainer
Grade two jumper’s knee is when your knee hurts before and after exercise, but the pain decreases
once you are warmed up.
The biggest risk factor is over training. Beginners are also at increased risk because they are not used to the high impact running has on the muscles and joints of the lower leg and foot.
Running on hard surfaces, Excessive pronation, Improper stretching, Lack of warm-up, Training too hard, Increasing mileage too quickly
Pain on the inside of the shin, Lumps and bumps over the bone, Pain when the toes or foot are bent downwards, A redness over the inside of the shin, If the pain is on the front outside of the shinbone it might be anterior compartment syndrome, which is a more severe problem - see your doctor.
Another common injury is a calf muscle strain which can be caused by twisting or pulling the muscles or by being hit in the back of the leg by a cricket ball. Chronic strains are usually the result of overuse.
An acute strain is caused by trauma or an injury such as a blow to the muscle or over stressing the calf muscle. Chronic strains are usually the result of overuse - prolonged, repetitive movement of the muscles.
Contributing factors include an inadequate warm up, lack of flexibility, fatigue and insufficient strength.
The calf muscles consist of the Gastrocnemius muscle, which is the big muscle at the back of the lower leg and the Soleus muscle, which is a smaller muscle lower in the leg, below the Gastrocnemius.
A sprain occurs when the ligaments around a joint are overstretched or tear. This is often due to a sudden wrench or twist which causes the bones of a joint to separate unduly.
Minor sprains and strains can be treated at home using the following measures:
Start treatment as soon as possible to reduce swelling and speed up recovery. The less swelling, the more blood can get to the injured part to start the repair process.
Apply the R.I.C.E. method listed below.
Another injury to consider is posterior impingement of the ankle. This injury is characterised by pain in the region of the achilles tendon. It is caused by maximal plantarflexion (pointing toes), most especially when this occurs at a time of impact.
This injury classically affects the right foot (of a right-handed bowler) at back foot impact during the delivery stride. This can be aggravated by uneven surfaces, which are commonly found at the run-up at the nets. There is a ‘pinching’ or impingement of the soft tissue at the back of the ankle.
Management may require surgery in a limited number of cases to reduce the impingement of tissue by bone or to release a restricted tendon. Other management would include strengthening to allow controlled landing of the foot and assessing the bowling biomechanics to prevent poor landing mechanics.
Coaches and players should be aware of the quality of the surfaces that fast bowlers practice on.
Managing Shoulder Problems
Management of throwers shoulder injury includes appropriate diagnosis and identification of all the potential causes of the shoulder pain. Pain management and rehabilitation are the two mainstays of treatment for this condition.
Rehabilitation is focused on both stability and strength around the shoulder joint. It is essential that there is a balance of strength around the joint.
Rehabilitation and correction of the cricketer’s throwing technique is important to prevent the recurrence of injury.
Management of traumatic injury of the shoulder includes appropriate diagnosis, which in some cases will require referral to an orthopaedic surgeon. If the injury is significant, surgery may be necessary.
Following this, it is essential that the cricketer is appropriately rehabilitated to prevent weakness of selected muscles, which may in turn lead to a future overuse injury.
The R.I.C.E. method:
- Do not apply heat during the first two days as this will only increase swelling.
- Use paracetamol for the first day of the injury, since it will reduce pain without increasing bleeding.
- Thereafter, ibuprofen (or other nonsteroidal antiinflammatories) or aspirin is a good choice. Don’t give aspirin to a child younger than 16 years.
- Arnica oil works well to reduce swelling.
- After 48 hours, start moving the limb gently, but only enough not to cause pain.
- Gradually increase the range of movement – let pain be your guide.
- Strains usually heal in about a week. Sprains may take up to three weeks to heal.
