People who suffer from neurotmesis often face a poor prognosis. They will more than likely never regain full functionality of the affected nerve, but surgical techniques do give people a better chance at regaining some function. Current research is focused on new ways to regenerate nerves and advance surgical techniques.

The first line of treatment is often to treat the patients pain with neuropathic drugs such as tricyclic antidepressants, serotonin reuptake inhibitors, and anticonvulsants. The second lines of drugs to treat pain are non-steroidal anti-inflammatories, tramadol, and opioids. Other techniques used to facilitate healing of the nerve and pain are either static or dynamic splinting that can both help protect the injured part as well as improve function. Sometimes surgery is an option, although the prognosis is still very poor of regaining function of the affected nerve. The goal of surgery is to join healthy nerve to unhealthy nerve. The most common surgical techniques include external neurolysis, end-to-end repair, nerve grafting, and nerve transfer from somewhere else in the body.

In terms of prognosis radial neuropathy is not necessarily permanent, though sometimes there could be partial loss of movement/sensation.Complications may be possible deformity of the hand in some individuals.

If the injury is axonal (the underlying nerve fiber itself is damaged) then full recovery may take months or years ( or could be permanent). EMG and nerve conduction studies are typically performed to diagnose the extent and distribution of the damage, and to help with prognosis for recovery.

The site and type of brachial plexus injury determine the prognosis. Avulsion and rupture injuries require timely surgical intervention for any chance of recovery. For milder injuries involving buildup of scar tissue and for neurapraxia, the potential for improvement varies, but there is a fair prognosis for spontaneous recovery, with a 90–100% return of function.

Treatment for brachial plexus injuries includes orthosis/splinting, occupational or physical therapy and, in some cases, surgery. Some brachial plexus injuries may heal without treatment. Many infants improve or recover within 6 months, but those that do not have a very poor outlook and will need further surgery to try to compensate for the nerve deficits. The ability to bend the elbow (biceps function) by the third month of life is considered an indicator of probable recovery, with additional upward movement of the wrist, as well as straightening of thumb and fingers an even stronger indicator of excellent spontaneous improvement. Gentle range of motion exercises performed by parents, accompanied by repeated examinations by a physician, may be all that is necessary for patients with strong indicators of recovery.

The exercises mentioned above can be done to help rehabilitate from mild cases of the injury. However, in more serious brachial plexus injuries surgical interventions can be used. Function can be restored by nerve repairs, nerve replacements, and surgery to remove tumors causing the injury. Another crucial factor to note is that psychological problems can hinder the rehabilitation process due to a lack of motivation from the patient. On top of promoting a lifetime process of physical healing, it is important to not overlook the psychological well-being of a patient. This is due to the possibility of depression or complications with head injuries.

The treatment and management of radial neuropathy can be achieved via the following methods:

- Physical therapy or occupational therapy

- Surgery(depending on the specific area and extent of damage)

- Splinting

According to medical professionals with the Cleveland Clinic, once an athlete suffers from an episode of cervical spinal cord, team physician or athletic trainer first stabilize the head and neck followed by a thorough neurologic inspection. If the injury is deemed severe, injured parties should be taken to a hospital for evaluation. Athletes that suffer from severe episodes of neurapraxia are urged to consult orthopaedic or spinal medical specialists. In mild cases of neurapraxia, the athlete is able to remove themselves from the field of play. However, the athlete is still advised to seek medical consultation.

In many cases recovery happens spontaneously and no treatment is needed. This spontaneous recovery can occur because distance between the injury location and the deltoid muscle is small. Spontaneous recovery may take as long as 12 months.

In order to combat pain and inflammation of nerves, medication may be prescribed.

Surgery is an option, but it has mixed results within the literature and is usually avoided because only about half of people who undergo surgery see any positive results from it. Some suggest that surgical exploration should be considered if no recovery occurs after 3 to 6 months. Some surgical options include nerve grafting, neurolysis, or nerve reconstruction. Surgery results are typically better for younger patients (under 25) and for nerve grafts less than six centimeters.

For some, recovery does not occur and surgery is not possible. In these cases, most patients’ surrounding muscles can compensate, allowing them to gain a satisfactory range of motion back. Physical therapy or Occupational therapy will help retrain and gain muscle tone back.

Stingers can be prevented by wearing protective gear, such as butterfly restrictors, designed to protect the head and neck from being forced into unnatural positions. This equipment is more feasible in positions where unrestricted head and neck movement is not required, such as American football lineman, than in positions like quarterback, where such movement is integral. Regardless of equipment, it is important to report even minor symptoms to an athletic trainer or team physician, and to allow appropriate recovery time.

Neurapraxia is often treated and cured by non-operative means. The primary goals of treatment are to maintain the proper nutrition of the paralyzed muscles, prevent contraction by the antagonists of the paralyzed muscles, and to consistently keep the joints mobile. A splint is often used in cases of neurapraxia because it is able to maintain a relaxed position of the paralyzed muscle. The splint prevents the paralyzed muscle from being overstretched either by the force of gravity or by other non-paralyzed antagonists. During the recovery period of neurapraxia, it is essential that the joints constantly undergo passive movement in order to preserve proper mobility. If joints are kept mobile, the limb has the best possible chance of benefit from the return of nervous function. Non-steroidal anti-inflammatory medications can also help to reduce swelling at the injury site. In addition to these non-operative remedies, it is suggested that muscles affected by neurapraxia be kept warm at all times. Circulation in the limb is stimulated with the use of heat.

Once voluntary movement has returned to the muscle, recovery and treatment continues by the participation in active exercises. Physical Therapy and Occupational Therapy are common sources of treatment during these early stages of restoration of active movement. Almost all cases of neurapraxia can be completely treated by non-operative means.

Currently, tendon transfers are being studied as a means of improving radial, medial, and ulnar nerve palsy.

Nerve injury is injury to nervous tissue. There is no single classification system that can describe all the many variations of nerve injury. In 1941, Seddon introduced a classification of nerve injuries based on three main types of nerve fiber injury and whether there is continuity of the nerve. Usually, however, (peripheral) nerve injury is classified in five stages, based on the extent of damage to both the nerve and the surrounding connective tissue, since supporting glial cells may be involved. Unlike in the central nervous system, neuroregeneration in the peripheral nervous system is possible. The processes that occur in peripheral regeneration can be divided into the following major events: Wallerian degeneration, axon regeneration/growth, and nerve reinnervation. The events that occur in peripheral regeneration occur with respect to the axis of the nerve injury. The proximal stump refers to the end of the injured neuron that is still attached to the neuron cell body; it is the part that regenerates. The distal stump refers to the end of the injured neuron that is still attached to the end of the axon; it is the part of the neuron that will degenerate but that remains in the area toward which the regenerating axon grows. The study of peripheral nerve injury began during the American Civil War and has greatly expanded to the point of using growth-promoting molecules.

The prognosis is usually good in terms of recovery. Rate of recovery depends on the distance from the site of injury, and axonal regeneration can go up to 1 inch per month. Complete recovery can take anywhere from 6 months to a year

Schwann cells provide the nerve with protection through the production of Nerve Growth Factors, and because these cells are intact this kind of nerve injury can be cured and normal feeling and sensations can be restored. Surgery can be done in order to help the nerve heal. The surgery will help with nerve regeneration, providing guidance to the nerve sprouts on where to attach on the proximal side of the injury. Damaged nerve axons can reattach themselves after surgery. Treatment of axonotmesis also consists of:

- Physical therapy or Occupational Therapy. Physical or Occupational therapy aims include:

- Pain relief

- Maintain range of motion

- Reducing muscular atrophy

- Patient education

- Use of assistive devices (Orthotic needs)

In terms of the prognosis of ulnar neuropathy early decompression of the nerve sees a return to normal ability (function). which should be immediate.Severe cubital tunnel syndrome tends to have a faster recovery process in individuals below the age of 70, as opposed to those above such an age. Finally, revisional surgery for cubital tunnel syndrome does not result well for those individuals over 50 years of age.

Most head injuries are of a benign nature and require no treatment beyond analgesics and close monitoring for potential complications such as intracranial bleeding. If the brain has been severely damaged by trauma, neurosurgical evaluation may be useful. Treatments may involve controlling elevated intracranial pressure. This can include sedation, paralytics, cerebrospinal fluid diversion. Second line alternatives include decompressive craniectomy (Jagannathan et al. found a net 65% favorable outcomes rate in pediatric patients), barbiturate coma, hypertonic saline and hypothermia. Although all of these methods have potential benefits, there has been no randomized study that has shown unequivocal benefit.

Clinicians will often consult clinical decision support rules such as the Canadian CT Head Rule or the New Orleans/Charity Head injury/Trauma Rule to decide if the patient needs further imaging studies or observation only. Rules like these are usually studied in depth by multiple research groups with large patient cohorts to ensure accuracy given the risk of adverse events in this area.

There are a number of colloquial terms used to describe radial nerve injuries, which are usually dependent on the causation factor:

- Saturday night palsy from falling asleep with one's arm hanging over the arm rest of a chair, compressing the radial nerve at the spiral groove.

- Honeymoon palsy from another individual sleeping on and compressing one's arm overnight. This can also refer to anterior interosseous nerve palsy from compression on the forearm resulting in an inability to flex the index and thumb tips. In this interpretation, it is a branch of the median nerve and not the radial nerve which is affected.

- Handcuff neuropathy from tight-fitting handcuffs compressing the superficial branch of the distal radial nerve; this is also referred to as cheiralgia paresthetica.

- Crutch palsy from poorly fitted axillary crutches.

- Squash palsy, from traction forces in a manner usually associated with the sport squash, can happen to squash players during prolonged periods between matches.

Anatomically, damage to the axillary nerve or suppression of it causes the palsy. This suppression, referred to as entrapment, causes the nerve pathway to become smaller and impulses cannot move through the nerve as easily. Furthermore, if trauma causes damage to the myelin sheath, or injures the nerve another way, this will also reduce the ability of nerve impulse flow.

Usually, an outside force is acting to suppress the nerve, or cause nerve damage. Most commonly, shoulder dislocation or fractions in the shoulder can cause the palsy. Contact sports such as football and hockey can cause the injury Other cases have been caused by repeated crutch pressure or injuries accidentally caused by health professionals (iatrogenesis). Furthermore, following an anterior shoulder operation; damage to the axillary nerve is possible and has been documented by various surgeons, thus causing axillary nerve palsy. Other possible causes include: deep infection, pressure from a cast or splint, fracture of the humerus, or nerve disorders in which the nerves become inflamed.

There are rare causes of axillary nerve palsy that do occur. For instance, axillary nerve palsy can occur after there is blunt trauma in the shoulder area without any sort of dislocation or fracture. Examples of this blunt trauma may include: being hit by heavy an object, falling on shoulder, a strong blow while participating in boxing, or motor vehicle accidents. Another rare cause of axillary nerve palsy can occur after utilizing a side birthing position. When the patient lies on their side for a strenuous amount of time, they can develop axillary nerve palsy. This rare complication of labor can occur due to the prolonged pressure on the axillary nerve while in a side-birth position. Some patients who are diagnosed with nodular fasciitis may develop axillary nerve palsy if the location of the rapid growth is near the axilla. In the case of Nodular Fasciitis, a fibrous band or the growth of a schwannoma can both press against the nerve, causing axillary nerve palsy.

An injury to the axillary nerve normally occurs from a direct impact of some sort to the outer arm, though it can result from injuring a shoulder via dislocation or compression of the nerve. The axillary nerve comes from the posterior cord of the brachial plexus at the coracoid process and provides the motor function to the deltoid and teres minor muscles. An EMG can be useful in determining if there is an injury to the axillary nerve. The largest numbers of axillary nerve palsies arise due to stretch injuries which are caused by blunt trauma or iatrogenesis. Axillary nerve palsy is characterized by the lack of shoulder abduction greater than 30 degrees with or without the loss of sense in the low two thirds of the shoulder. Normally the patients that have axillary nerve palsy are involved in blunt trauma and have a number of shoulder injuries. Surgery is not always required to solve the problem (information from: Midha, Rajiv, Zager, Eric. Surgery of Peripheral Nerves: A Case-Based Approach. Thieme Medical Publishers, Inc. 2008.)

People with diabetes mellitus are at higher risk for any kind of peripheral neuropathy, including ulnar nerve entrapments.

Cubital tunnel syndrome is more common in people who spend long periods of time with their elbows bent, such as when holding a telephone to the head. Flexing the elbow while the arm is pressed against a hard surface, such as leaning against the edge of a table, is a significant risk factor. The use of vibrating tools at work or other causes of repetitive activities increase the risk, including throwing a baseball.

Damage to or deformity of the elbow joint increases the risk of cubital tunnel syndrome. Additionally, people who have other nerve entrapments elsewhere in the arm and shoulder are at higher risk for ulnar nerve entrapment. There is some evidence that soft tissue compression of the nerve pathway in the shoulder by a bra strap over many years can cause symptoms of ulnar neuropathy, especially in very large-breasted women.

Stingers are best diagnosed by a medical professional. This person will assess the athlete's pain, range of head and neck motion, arm numbness, and muscle strength. Often, the affected athlete is allowed to return to play within a short time, but persistent symptoms will result in removal. Athletes are also advised to receive

regular evaluations until symptoms have ceased. If they have not after two weeks, or increase, additional tests such as magnetic resonance imaging (MRI) can be performed to detect a more serious injury, such as a herniated disc.

The order of treatments applied depends on whether the athlete's main complaint is pain or weakness. Both can be treated with an analgesic, anti-inflammatory medication, ice and heat, restriction of movement, and if necessary, cervical collar or traction. Surgery is only necessary in the most severe cases.

Electrical stimulation can promote nerve regeneration. The frequency of stimulation is an important factor in the success of both quality and quantity of axon regeneration as well as growth of the surrounding myelin and blood vessels that support the axon. Histological analysis and measurement of regeneration showed that low frequency stimulation had a more successful outcome than high frequency stimulation on regeneration of damaged sciatic nerves.

Surgery can be done in case a nerve has become cut or otherwise divided. Recovery of a nerve after surgical repair depends mainly on the age of the patient. Young children can recover close-to-normal nerve function. In contrast, a patient over 60 years old with a cut nerve in the hand would expect to recover only protective sensation, that is, the ability to distinguish hot/cold or sharp/dull. Many other factors also affect nerve recovery. The use of autologous nerve grafting procedures that involve redirection of regenerative donor nerve fibers into the graft conduit has been successful in restoring target muscle function. Localized delivery of soluble neurotrophic factors may help promote the rate of axon regeneration observed within these graft conduits.

An expanding area of nerve regeneration research deals with the development of scaffolding and bio-conduits. Scaffolding developed from biomaterial would be useful in nerve regeneration if they successfully exhibit essentially the same role as the endoneurial tubes and Schwann cell do in guiding regrowing axons.

Cubital tunnel syndrome may be prevented or reduced by maintaining good posture and proper use of the elbow and arms, such as wearing an arm splint while sleeping to maintain the arm is in a straight position instead of keeping the elbow tightly bent. A recent example of this is popularization of the concept of cell phone elbow.

Treatment varies. In most cases, the best treatment is to remove the cause of compression by modifying patient behavior, in combination with medical treatment to relieve inflammation and pain. Whatever the cause, typical treatment takes several weeks to months—depending on the degree of nerve damage. Typical treatment options include:

- Active Release Technique (ART) soft tissue treatment

- Wearing looser clothing and suspenders rather than belts

- Weight loss if obesity is present

- Non-steroidal anti-inflammatory drugs (NSAIDs) to reduce inflammatory pain if pain level limits motion and prevents sleep

- Reducing physical activity in relation to pain level. Acute pain may require absolute bed rest

- Deep tissue massage to reduce tension in the gluteal muscles, most commonly the gluteus maximus. The tensor fasciae latae may also be implicated.

The lateral cutaneous nerve of the thigh can occasionally be damaged during laparoscopic hernia repair, or scarring from the operation can lead to meralgia paraesthetica.

For lower pain levels, treatment may involve having the patient:

- Seek appropriate physical therapy, such as stretching and massage, which plays a large role in the management of pain

- Learn to perform inguinal ligament stretching (from a physical therapist or from a YouTube video) which can rapidly relieve symptoms

- Use rest periods to interrupt long periods of standing, walking, cycling, or other aggravating activity

- Lose weight, and exercise to strengthen abdominal muscles

- Wear clothing that is loose at the upper front hip area

- Apply heat, ice, or electrical stimulation

- Take nonsteroidal anti-inflammatory medications for 7–10 days

- Remove hair in affected area (shave)

- Lidocaine patches (must shave area first)

- Titanium dioxide patches to interfere with the electrostatic effect of the nerves on the surface of the skin

Pain may take significant time (weeks) to stop and, in some cases, numbness persists despite treatment. In severe cases, the physician might perform a local nerve block at the inguinal ligament, using a combination of local anaesthetic (lidocaine) and corticosteroids to provide relief that may last several weeks. Pain modifier drugs for neuralgic pain (such as amitriptyline, carbamazepine or gabapentin) may be tried, but are often not as helpful in the majority of patients.

Persistent and severe cases may require surgery to decompress the nerve or, as a last resort, to resect the nerve. The latter treatment leaves permanent numbness in the area.

Treatment for ulnar neuropathy can entail:

NSAID (non-steroidal anti-inflammatory) medicines. there is also the option of cortisone. Another possible option is splinting, to secure elbow, a conservative procedure endorsed by some. In cases where surgery is needed, cubital tunnel release, where the ligament of the cubital tunnel is cut, thereby alleviating pressure on nerve can be performed.

Treatment for the common occurrence of ulnar neuropathy resulting from overuse, with no fractures or structural abnormalities, is treatment massage, ice, and anti-inflammatories. Specifically, deep tissue massage to the triceps, myofascial release for the upper arm connective tissue, and cross-fiber friction to the triceps tendon.

Surgical decompression can give excellent results if the clinical picture and the EMG suggest a compression neuropathy.

In brachial plexus neuritis, conservative management may be more appropriate.

Spontaneous recovery has been reported, but is said to be delayed and incomplete.

There is a role for physiotherapy and this should be directed specifically towards the pattern of pain and symptoms. Soft tissue massage, stretches and exercises to directly mobilise the nerve tissue may be used.⁠
