The peripheral nervous system

The peripheral nervous system consists of all the nerves outside of the brain and the spinal cord. Whether caused by injury, surgery, or conditions such as diabetic neuropathy, damage to the peripheral nerves can lead to debilitating chronic pain that is often very difficult to diagnose and therefore treat.

We help you with life-changing procedures, including nerve transplant surgery for those who have suffered traumatic injuries to the brachial plexus or other types of paralysis.

Identifying and treating nerve injuries and conditions

Brachial plexus injury

Symptoms can include loss of sensation or partial or complete paralysis in all or parts of the arm and hand becoming paralysed and numb. Most common after an impact to the shoulder or neck, usually following a motorbike accident or sporting injury.

Lumbosacral plexus injury

Usually injury received after a severe trauma to the lower part of the body with pelvic or hip fractures or dislocation leaving you with sensation loss and/or movement in the hip, knee, ankle, foot or toes.

Nerve compression

A number of different peripheral nerves may have their normal function impaired by entrapment with abnormal compression causing loss of sensation and pain. Most common is carpal tunnel syndrome.

Nerve tumours

Benign and malignant tumours can be removed without any added neurological problems by working inside the nerve.

Restoring limb function with surgical reconstruction

We use several methods to restore limb function following a nerve injury, these include muscle transfers, nerve transfers and joint fusions.

PNI Diagnostics
Latest diagnostic technology

Diagnostic imaging is fundamental for peripheral nerve damage and injury. Identifying the cause of your pain is not always clear and many of our patients have seen several other clinicians without finding the right diagnosis and relief for their pain. This is why we always invest in the latest and most accurate diagnostic equipment. To get the right diagnosis first time we use MRI, nuclear medicine (SPECT CT and PET CT), CT, neurophysiology (EMG, nerve conduction studies) and nerve blocks. Our technicians, physiologists, reporting clinicians and radiologists are all specialists in their field — using our machines to get the most precise information possible.

PNI caring for family
Caring for you like family

We treat patients from across the UK and internationally. We fully understand staying in hospital can be an anxious time which is why we surround you with an experienced team to support you fully throughout your treatment with us.

It’s by working together again and again they can innovate – improving a technique, or developing an approach – to transform care for you. The unit is supported by a multi-disciplinary team of specialists including oncologists, neurophysiologists, anaesthetists, radiologists and specialist physicians using the very latest endoscopic and diagnostic technology. Our specialist nurses are chosen for their high level of training and experience. We have everything we need to care for our patients – including the highest level intensive care units (ICU).

Whether you're experiencing pain from a previous nerve injury, have lost sensation, or you've experienced a traumatic injury to a nerve, we can offer the highest levels of care.

  • Function loss from old nerve injury

    Need to know

    When a nerve has been damaged many years before and has left the patient with permanent loss of function. in selected cases, the function can be partially restored by detaching muscles that perform another movement and redirecting them onto the paralysed muscles through surgery.

  • Nerve pain

    Need to know

    Nerves branch out from the spinal cord to other parts of your body. These enable messages to travel from your brain to other parts of your body; it's down to this that we're able to run and walk. The nerves in your back carry messages about sensations and muscle controls to your brain. When these nerves...

  • Peripheral nerve tumours

    Need to know

    Nerve tumours can develop within your nerves. As the nerves carry vital signals from your brain to the muscles in your body (allowing you to move and feel sensations), tumours can lead to loss of movement and pain if malignant. In most cases, the tumours are benign and can be removed with surgery.

  • Peripheral neuropathy

    Need to know

    The peripheral nervous system is a network of nerves in your body. It controls your hands, feet and arms. Sometimes, these nerves can be damaged, leading to pain, weakness and numbness. This condition is known as peripheral nephropathy. It affects 1 in 10 people over the age of 55. If you're experiencing...

  • Brachial plexus injury

    Need to know

    The brachial plexus is a group of five nerves which stem from the spinal cord in the neck. It connects the brain and spinal cord to the upper limb, allowing us movement and sensation. Brachial plexus injuries happen when the arm is forcefully pulled or stretched. Falls, motorbike and car accidents and...

  • Brachial plexus injuries during birth

    Need to know

    A brachial plexus injury can affect newborn babies, causing weakness in the baby's hand, arm and shoulder. The brachial plexus is a group of nerve fibres stemming from the spine and through the neck. If pressure is applied to the baby's head during delivery, these nerves can become damaged causing weakness...

  • Correction of brachial plexus injuries in children

    Need to know

    This procedure aims to correct shoulder deformities in children caused by brachial plexus palsy — muscle weakness in the shoulder, arm and hand. This condition is caused by injury to the brachial plexus during birth. The brachial plexus is a group of nerve fibres stemming from the spine...

  • Decompression and neurolysis of nerves

    Need to know

    Peripheral nerves serve the upper and lower parts of your body. Carpal tunnel syndrome (trapped nerve in the wrist) is a common example in the upper body and tarsal tunnel (trapped nerve in the ankle) is an example of the lower body. There are many causes of peripheral nerve damage. Traumatic impact,...

  • Nerve repair

    Need to know

    Nerve repair surgery aims to restore feeling and muscle use in a damaged area — it's a complex and delicate surgery. Our nerves are like special cables which carry messages to our brain and other parts of the body. When a nerve becomes damaged or injured, it may stop sending these signals,...

  • Resection of nerve tumours

    Need to know

    This procedure aims to remove peripheral nerve tumours as completely as possible, without damaging the nerve. Certain types of tumour (schwannomas) can be removed from the surface of a nerve, while others grow within a nerve (neurofibroma). In these cases, the nerve may be opened up so that the tumour...

  • Repair of brachial plexus injury

    Need to know

    This procedure aims to reattach or repair one of of your brachial plexus nerves. The brachial plexus is a group of five nerves stemming from the spinal cord in the neck. It connects the brain and spinal cord to nerves in the shoulder and arms, allowing movement and sensation. You have one brachial...

  • Peripheral nerve release

    Need to know

    Peripheral nerves run from your central nervous system (brain and spinal cord) to control movement and sensation in your muscles and limbs. If a nerve becomes pinched due to an injury or condition, it can cause pain, tingling or a lack of sensation. A surgical procedure can relieve these symptoms.

If you are suffering from a peripheral nerve injury it is important to get medical care as soon as possible because early diagnosis and treatment in some cases can prevent complications and permanent injury. At the peripheral nerve injury unit at The Wellington Hospital we provide better outcomes daily for patients suffering nerve damage

Mr Michael Fox, Consultant Orthopaedic Surgeon

Treating patients from birth

Infant brachial plexus injury is one of the most common types of birth injuries affecting thousands of infants each year.

A brachial plexus injury received during a complicated birth can affect newborn babies causing weakness in the baby's hand, arm and shoulder.

At The Portland Hospital we regularly treat infants providing them with the best possible outcomes.
