Tendon ruptures and what to do about them

Tendon ruptures and what to do about themTendon ruptures are fairly uncommon however they can and do occur. They are often associated with sharp sudden movements, a sudden onset of symptoms and considerable loss of function or disability. Before we can discuss what you should do if you have or suspect that you have a tendon rupture, we first need to discuss what a tendon is.

What are Tendons?

Tendons are tough connective tissue bands or cords that connect muscle to bone. They are responsible for transmitting the forces generated by muscles to the bones that they are connected to. They consist of various types of collagen organised into fascicles. Theses fascicles are then organised into bundles, which are then surrounded by a membrane called the epitenon. This unit is then described as the tendon.

What can go wrong with Tendons?

There are broadly 2 categories of tendon problems tendon rupture and  tendinopathies.

Tendon rupture

Tendons are extremely strong as mentioned above, therefore normally they will only rupture under fairly high loads unless there is some underlying problem affecting the strength of the tendon. For example certain antibiotics such those of the fluroquinolone class, the patient having rheumatoid arthritis or gout, there being a previous history of tendinopathy or previous steriod injection. The later being one of the reasons for the reluctance of medical staff to repeatedly inject steriods.

A paper from 2015 found that approximately 10% of those who sustained an achilles tendon rupture had  had a pre-existing tendon problem. Therefore the take home message would be that if you participate in a sport or activity, where you are placing a substantial amount of load on your tendons. It would be prudent to address any tendon discomfort properly and not to just ingnore it.

In general rupturing a tendon is not that common with the same paper referenced above reporting an incidence of 7 per 100,000 for achilles tendon ruptures and noting that over 80% occured when taking  part  in recreational sport.

Obviously any tendon can potentially rupture, however the four that commonly occur in an otherwise healthy population are the quadriceps, achilles, rotator cuff and biceps tendons.

Generally the causes of tendon rupture are;

Direct truama to the area.

Eccentric loading this is when the muscle contracts as its being stretched in the opposite direction. For example if the patient tries to lower an object that is too heavy(Biceps tendon rupture) or landing after jumping(Achilles tendon or Quadriceps tendon rupture)

Forcible contraction against excessive resistance. for example explosive push off when sprinting(Achilles tendon rupture) or lifting heavy objects or pushing hard against an immovible object eg a jammed door(biceps or rotator cuff tendon tear)

How to recognise if you have ruptured a tendon

Generally a tendon rupure will have some or all of the following signs or symptoms:

An audible pop or snap

Sudden onset of extreme debilitating pain

Rapid marked bruising

Marked muscle weakness

An inability to use or move the affected leg or arm

An inability to weight bear

In our clinical experience if you have sustained a tendon rupture you will be in absolutely no doubt that you have sustained a significant injury. If it is affecting your leg you will be unable to walk and if it is affecting your arm you will have lost the ability to use your arm.

 

What should you do if you think that you have ruptured a tendon

You should attend A & E if you have the above symptoms and you think that you may have ruptured a tendon. The staff in A & E will assess you and if there is a rupture present, decide whether it is complete or partial. You may need an X Ray to assess if there is any bony damage present. For example an avulsion fracture where the tendon and a small piece of bone are pulled off the bone.

What happens next will depend on the site and extent of the tendon rupture. For example quadriceps ruptures will normally be surgically repaired. Whilst biceps, achilles and rotator cuff tendon ruptures will often be managed non surgically initially.

For a tendon rupture that affects your ability to walk you will need crutches or some other walking aid. In the case of an achilles tendon rupture that is being managed non surgically you will need a moonboot with a heal raise.

What happens next

After a period of immobilistion which will vary depending on which tendon has been injuried and the management approach which has been chosen. The patient will start the rehabilitation journey.

It is extremely important that the healing tendon is loaded optimally to facilitate as full and as quick a recovery as is possible, whilst minimising any loss of function and the risk of re-rupture.

There is good research evidence that collegen synthesis and collegen remodeling is positively affected by loading. These two processes are essential for a strong and pliable repair. Therefore a rehabilitation approach which includes stretching and range of movement exercises to restore range of movement, strengthening exercises to restore power and strength and eventually end stage rehabilitation including plyometrics and a graded return to training and participation in sport or other activities is essential.

However It is also essential to get the timing, volume and intensity of these types of training right. Otherwise the tendon may be lengthened  excessively if stretching is started too early or the tendon may rupture if a strength or plyometric programme is too aggressive, implented too soon or there is simply not enough recovery planned.
