This plexus extends from the spinal cord through the cervicoaxillary canal in the neck over the first rib and into the armpit. We present a case of isolated lower brachial plexus palsy with the presumed diagnosis of Klumpke palsy.
Brachial plexus injuries may reduce or eliminate the communication between the spinal cord and the shoulder arm wrist and hand.
Lower brachial plexus palsy. Klumpke palsy was described over a century ago in adults who sustained injuries to the lower roots of the brachial plexus. Whereas some clinicians consider the birth palsy type to be of historical interest only others do not believe it exists. We present a case of isolated lower brachial plexus palsy with the presumed diagnosis of Klumpke palsy.

We present a case of isolated lower brachial plexus palsy with the presumed diagnosis of Klumpke palsy.
In contrast Klumpkes or Klumpke-Dejerine palsy affects the lower roots of the brachial plexus C8 T1. Both these types of lesions usually involve a specific injury mechanism that results in the excessive stretching of either the upper plexus due to an increase of the angle between the shoulder and head or the lower plexus associated with hyper abduction of the arm Figure 3. Lower Brachial Plexus Injury.
Klumpkes Palsy Site of injury Inferior trunk of the brachial plexus C8T1 Mechanism Traction injury due to excessive force placed on an abducted shoulder results in violent stretching - tearing of the lower portion of the brachial plexus Causes Klumpkes palsy is the rarest brachial plexus syndrome. Lower brachial plexus injuries occur when the arm and shoulder are forced upward increasing the angle between the arm and the chest. This illustration shows a left plexus.
Reproduced with permission from the Mayo Foundation for Medical Education and Research. Brachial plexus injuries may reduce or eliminate the communication between the spinal cord and the shoulder arm wrist and hand. This may mean both loss of feeling and loss of use of your arm or hand or both.
The severity of a brachial plexus injury varies. In some people function and feeling return to normal over days to weeks. Brachial plexus injuries are classically defined as Erbs or Klumpkes palsies.
Erbs upper type palsy involves cranial nerves C5 and C6. The brachial plexus is a network of nerves formed by the anterior rami of the lower four cervical nerves and first thoracic nerve C5 C6 C7 C8 and T1. This plexus extends from the spinal cord through the cervicoaxillary canal in the neck over the first rib and into the armpit.
It supplies afferent and efferent nerve fibers to the chest shoulder arm forearm and hand. Brachial plexus palsies can be divided anatomically into upper plexus involving cervical nerve roots C5C7 lower plexus involving spinal nerve roots C8 and T1 and total plexus palsies. Isolated involvement of the lower plexus is extremely unusual as exemplified by the fact that no case was identified in the British Paediatric Surveillance Unit survey of CBPP.
Lower brachial plexus lesion Klumpkes palsy A Klumpkes palsy also referred to as Dejerine-Klumpke palsy is a paralysis of the arm that is caused by an injury to the lower roots of the brachial plexus. The most commonly involved root is C8 but T1 can also be affected. Klumpke palsy also known as Klumpke paralysis is a type of lower brachial plexus injury that affects brachial plexus injury at birth.
It is caused by an injury to the first thoracic nerve T1 and the eighth cervical nerve C8 all of which come from the spinal cord. The brachial plexus is a network of spinal nerves that. Brachial plexus is the network of nerves which runs through the cervical spine neck axilla and then into arm or it is a network of nerves passing through the cervico axillary canal to reach axilla and innervates brachium upper arm antebrachium forearm and handIt is a somatic nerve plexus formed by intercommunications among the ventral rami roots of the lower 4 cervical nerves C5-C8 and the.
In most cases of brachial plexus birth palsy it is the upper nerves in the brachial plexus that are affected. This is known as Erbs palsy. The infant may not be able to move the shoulder but may be able to move the fingers.
If both the upper and lower nerves are stretched the condition is usually more severe than just Erbs palsy. Erbs palsy is a paralysis of the arm caused by injury to the upper group of the arms main nerves specifically the severing of the upper trunk C5C6 nerves. These form part of the brachial plexus comprising the ventral rami of spinal nerves C5C8 and thoracic nerve T1.
