The thick tissue that
connects your muscles to the bone is called a tendon. Tendons are important for
carrying out the full range of movements of a particular muscle.
In the hand, there
are two sets of tendons that control all of the movements of the hand. The
flexor group of tendons attaches the muscles on the palmar side of the hand to
flex or bend the hand and fingers. The extensor group, on the other hand,
allows the hand to stretch out or extend. Extensor tendons and muscles are
found on the backside of the hand.How Can a Tendon
It’s not uncommon for
a tendon to get torn, or completely avulsed. This is more common in active
people who lift heavy weights. Crushing trauma to the hand can also result in
More frequently, hand
tendons are injured, as a result of contact sports and strength training,
accidental cuts, animal bites, traffic accidents or certain debilitating
chronic diseases such as advanced rheumatoid arthritis.How Does Tendon
When a tendon is torn
it can cause pain when the fingers are bent or straightened. Sometimes the
injury can be severe enough to cause numbness and swelling over the affected
area.How is a Tendon
A complete physical
examination should usually be enough for a qualified physician to diagnose a
tendon tear. However certain imaging tests such as an X-ray or an MRI scan can
further confirm the diagnosis.Hand Tendon Surgery
Depending upon the
extent of disease your doctor will decide the best course of action for you.
Sometimes the tears are minute enough to be treated with rest and bracing. In
most cases of tendon tears, however, surgery will be required.
When an extensor tendon is injured, the surgical procedure can be performed under local anaesthesia. If a flexor tendon is damaged, however, general anaesthesia might become necessary because of the complex nerve anatomy in the palmar side of the hand.What is the
Generally it can take
up to two months to fully recover after surgery. The prognosis is excellent if
proper post-operative care and rehabilitation is provided during this time
period. Hand physiotherapy and exercises also help to restore function.
