Nerve Damage Following Spinal Surgery
During spinal surgery, the chance of nerve damage due to bruising or accidental scalpel cuts is high. Nerves can also be damaged if the tissues around them become inflamed. Sometimes, the damaged nerves can be repaired, but they can also be permanently damaged. Therefore, damage to nerves after spinal surgery can be a very serious problem. According to medical malpractice statistics in the United States, 250,000 people in the U.S. die every year from medical errors and negligence, which is why it’s important to have a Philadelphia medical malpractice lawyer on your side if you or a family member have been severely injured due to an error by a medical professional.
Our nervous system is a critical component of our bodies – the two types of nerves are central and peripheral. Neurons form the network of nerves, which allows coordination of various physical activities and the regulation of bodily functions. Therefore, injuries to the nervous system are very problematic. Injuries to the nerves vary by their form, which makes it hard to group them by types. They were eventually categorized into three different kinds of nerve injuries in 1943 by Sir Herbert Seddon, neurotmesis, neurapraxia, and axonotmesis.
- Neurotmesis injuries – the worst type of nerve injury. It is identifiable by lacerations, contusions or stretches. With neurotmesis, the connectivity of the connective tissues and their axons is disrupted. The nerve’s sheath gets separated from the nerve. In other words, the nerve is snapped into two pieces. Partial recovery is all that can be hoped for with this type of injury.
- Neurapraxia injuries – do not alter the nerve’s structure but the injury interrupts impulse conduction. Neurapraxia normally is the result of minor external injuries, which cause loss of motor and sensory functions. That prevents coordination of some complex body movements. These injuries can be fully healed in about seven weeks. Neurapraxia injuries also disrupt blood supply and compress the nerves.
- xonotmesis injuries – the myelin sheath and neuronal axon are disrupted. The other nerve components are unaffected, including the endoneurium, epineurium, perineurium and Schwann cells. This type of injury paralyzes motor, sensory and autonomic nerves and is more serious than neurapraxia.
Nerve Damage Caused by Surgery
Nerve damage can be caused by other factors than the cuts and bruises that may result from mishandled surgical tools. For example, anesthesia can also cause nerve damage. The anesthetic medications or even the syringe used to give them might cause damage to the tissues of the nerves. The discomfort might be long-lasting or temporary. A spinal epidural, which is used in a spinal tap or during an infant’s delivery, can damage the nerves of the spinal cord if performed incorrectly.
Symptoms of Surgical Nerve Damage
There are several symptoms of nerve damage that can be present after surgery.
- You might experience numbness or a tingling sensation in the region of the damaged nerve. This is sometimes referred to as loss of innervation or “pins and needles.” The symptoms do not have to be in the area where the nerve was actually damaged due to the complex nature of the nervous system’s network structure. The symptoms could manifest far away from the injury.
- You could experience weakness in the ankles or feet if a nerve is damaged during knee surgery.
- Knee surgery can also cause a condition called “foot drop.”
- Damage to the spinal nerves can cause difficulty walking or a change in your regular walking pattern.
- Neuropathic pain, which burns severely, can be caused by an injury to the nerves of the spine or other areas during nerve surgery.
- Another injury that might be caused by knee surgery is dragging toe.
