Understanding Shoulder or Rotator Cuff Injuries From Car Accidents

Car Accidents Can Exert Tremendous Forces on Shoulders

During a car accident, the driver and passengers’ shoulders are subjected to many strong forces that can result in significant injuries.

Although seat belts are designed to protect and do their job well, when a vehicle suddenly stops or collides with another object, the body continues to move forward due to inertia. As a result, the shoulders push against the restraints which can exert a concentrated, significant amount of pressure.

Meanwhile, if the collision is severe enough that the airbags deploy, the shoulders can be jolted or bruised even more as airbags emerge with a lot of force and speed. Additionally, the driver’s proximity to the steering wheel can cause more direct trauma, especially if they’re thrown forward onto it. Combined, all of these forces make shoulders more vulnerable to many kinds of injuries, ranging from fractures and dislocations to soft tissue damage.

What is Whiplash in Shoulder?

Despite usually affecting the neck due to the rapid and acute back-and-forth motion caused by sudden deceleration, the impact of whiplash also often radiates down into the shoulders, too. The motion of a sudden stop can strain shoulder muscles and ligaments, and can also lead to pain and stiffness. As a result, a car accident victim may suffer from shoulders that have inflammation, decreased range of motion, or associated injuries alongside the more commonly recognized neck symptoms of whiplash.

The anatomy of a shoulder is complex yet delicate. The ball-and-socket joint is made up of bones, ligaments, tendons, and muscles, all working together to allow arm articulation and movement in various directions. When whiplash strains the muscle and ligaments, often caused by rear-end or front-end car collisions as well as physical abuse, sports injuries, or any sudden jolt, the shoulder’s function can be negatively impacted.

There are several risk factors that can elevate the likelihood of shoulder whiplash injuries in a car accident, too. Drivers who sit closer to the steering wheel, have pre-existing shoulder conditions, weren’t wearing a seatbelt, or have a poorly positioned headrest can all expect to have more severe injuries.

A primary symptom of whiplash is pain that radiates from the neck down into one or both shoulders, stiffness in the shoulders, headaches at the base of the skill, and a generally decreased range of motion. A medical professional can diagnose whiplash with a physical examination or with imaging tests like X-rays, MRIs, and CT scans.

There are several non-invasive treatment options to help mitigate the pain and long-term effects of whiplash, including pain management medication, physiotherapy, and hot or cold compress, while in some severe cases, surgery might be required to repair internal damage.

It’s important to understand that while whiplash can affect the shoulder, not every case will. Each individual’s experience and recovery will differ based on various factors.

Usually, rehabilitation via physical therapy is enough for victims to regain strength and mobility, especially when it’s combined with rest and avoiding strenuous activities. Mild to moderate cases of whiplash generally recover fully within a few weeks or a few months, but severe cases can take longer, sometimes over a year. However, if left untreated, whiplash can have long-term complications including chronic pain, prolonged muscle weakness, or decreased range of motion.

Depending on the type of treatment needed, whether that’s needing an orthopedic surgeon, physiatrist, physical therapist, or chiropractor, the estimated medical cost varies greatly based on the severity of the injury and the treatment chosen, but it can range from only a few hundred dollars to several thousand or more.

While exact statistics for shoulder pain as a result of whiplash aren’t readily available, more than 2 million Americans report standard whiplash injuries every year. Drivers and passengers alike can prevent potential whiplash during a car accident by ensuring their headrests are properly positioned, wearing their seatbelts, and regularly exercising to strengthen the neck and shoulder muscles.

What is Shoulder Dislocation?

The sudden and forceful impact of a car accident can jolt the body in many directions, resulting in arms being violently thrust forward, backward, or to the side. The abrupt motion often applies a lot of excessive force to the shoulder joint, well past what it can withstand, and pushes the head of the upper arm bone (humerus) out of the shoulder socket (glenoid) which results in a shoulder dislocation.

Side impacts or rollovers, as well as things like the position of the arm or arms during the crash, and the presence of direct trauma from impact with an object, can all further increase the likelihood of a dislocated shoulder.

The ball-and-socket shoulder joint, formed by the humerus and glenoid, is one of the body’s most mobile joints but direct blows, falls, or even extreme rotation of the shoulder that might occur in sports, car accidents, or other traumatic incidents, can all result in dislocation.

Unfortunately, previous shoulder dislocations increase the risk of additional dislocations, as does ligamentous laxity, participating in high-contact sports, or having a condition that causes muscle weakness.

Diagnosing a dislocated shoulder is fairly easy, as there is often a visible deformity, swelling, pain, inability to move the joint, numbness, and tingling around the area, although a physical examination and imaging tests, most commonly X-rays, can confirm the dislocation and check for fractures. Orthopedic surgeons, sports medicine physicians, physical therapists, and sometimes emergency medicine doctors (for initial treatment) can address shoulder dislocations.

Immediate medical attention will be needed to relocate the shoulder, while ongoing treatment options usually necessitate immobilization of the arm in a sling, pain medication, and physical therapy. People suffering from mild dislocations usually recover in a few weeks, but more severe cases or those requiring surgery can take several months.

Doctors usually recommend that people who suffer from a shoulder dislocation rest before following a guided rehabilitation program designed to restore strength and flexibility. Physical therapy is often vital, and can reduce the risk of long-term issues like future dislocations, chronic instability, and possibly even the development of arthritis in the joint.

For shoulder dislocations, the associated medical costs for treatment and recovery vary based on severity and treatment, of course. It can range from a few hundred dollars to several thousand dollars or more for emergency care, not including follow-up care, physical therapy, or potential surgeries.

Statistics show that shoulder dislocations represent about 50% of all major joint dislocations seen in emergency departments, but they can be prevented by using protective gear in contact sports, avoiding situations where the arm could be forcibly leveraged away from the body, and by exercising to strengthen the shoulder muscles.

What is a Separated Shoulder?

In a car accident, a shoulder separation, distinct from a dislocation, occurs when there’s a forceful trauma directly to the top of the shoulder. This trauma can be caused by the shoulder’s violent collision with elements like the car door, window, or ground in the case of a rollover.

The strong impact damages (or sometimes tears) the ligaments that connect the collarbone (clavicle) to the shoulder blade (scapula) at the acromioclavicular (AC) joint, and the result is the separation of these bones. Additionally, the sudden jerk from the seatbelt or abrupt deceleration upon impact can also contribute to the cause of a separated shoulder, especially if the arm is positioned away from the body during the crash.

It’s not always a car accident that causes a shoulder separation, too, as direct blows to the shoulder, participating in contact sports, falls onto an outstretched hand or shoulder, or a sudden pull, like those experienced in car accidents, can all have the same result. Previous shoulder injuries and conditions that weaken ligaments also increase the possibility of separated shoulders.

A separated shoulder can be excruciatingly painful, and is usually accompanied by pain at the top of the shoulder, swelling, bruising, a bump or raised area over the joint in more severe cases, and limited shoulder movement overall. A doctor’s physical examination and imaging tests like X-rays or MRI can confirm the diagnosis.

Depending on the severity of the separated shoulder, which is rated from Type I to Type VI, treatment can range from rest, ice, and over-the-counter pain medications to surgery for more serious separations.

Mild separations can heal in a few weeks, but severe cases or ones that require surgery may take several months for a full recovery. For the latter, medical professionals like orthopedic surgeons, sports medicine physicians, and physical therapists are usually needed to treat shoulder separations.

Physical therapy, combined with rest and avoiding strenuous activities, is usually all that’s needed to regain strength and mobility. If shoulder separations aren’t properly treated, they can lead to chronic pain, instability, or even osteoarthritis in the joint.

Because of the vast difference in types of shoulder separations, from mild sprains to full tears requiring surgery, the medical cost associated with this type of injury varies widely. It may only cost a few hundred dollars for the less severe issues, while shoulder separations that require surgery can cost significantly more.

The exact statistics on the number of shoulder separations resulting specifically from car accidents are scarce, but it’s a common injury in contact sports and traumatic incidents. However, to decrease the odds of suffering from a shoulder separation, always use protective gear in risky activities, strengthen the shoulder muscles through regular exercise, and take proper safety precautions in vehicles like always wearing a seat belt and making sure headrests are adjusted appropriately.

What is a Rotator Cuff Tear?

Car accidents can result in rotator cuff tears either from a single traumatic event or accumulated stress during the incident. When the car gets hit or stops suddenly, the driver or passenger’s body and, in particular the arms, may jerk violently. Abrupt movements such as bracing for the impact, gripping the steering wheel, or being thrown forward, or direct trauma to the shoulder from a physical impact, can overload and strain the rotator cuff tendons. As a result, partial or complete tears are common. Additionally, forces from seat belts, airbags, and the body’s natural protective mechanisms can also contribute to this sensitive group of tendons in the shoulder being injured.

The rotator cuff includes four different muscles (supraspinatus, infraspinatus, teres minor, and subscapularis) along with their associated tendons which encircle the head of the humerus. Together, the rotator cuff allows the arm to lift and rotate while also keeping it centered in the shoulder socket. A torn rotator cuff is the result of tears (or damage to) these tendons and muscles that help stabilize and move the shoulder joint.

Other than traumatic events like car accidents, rotator cuff injuries can be caused by general wear and tear over time, heavy lifting, or repetitive overhead motions. Age, involvement in certain sports or jobs that require repetitive arm motions, bone spurs, and previous shoulder injuries, are all valid risk factors that can lead to rotator cuff tears.

Although a physical examination and imaging tests such as MRI, ultrasound, or X-ray, are usually needed to officially diagnose a rotator cuff tear, there are usually some symptoms that can indicate the issue such as pain while resting and at night, weakness in lifting or rotating the arm, and a crackling sensation upon moving the shoulder.

Orthopedic surgeons, sports medicine specialists, and physical therapists can all diagnose and treat rotator cuff tears, but the treatment depends on the severity of the injury. Often, rest, physical therapy, pain relief medications, corticosteroid injections, or surgery for larger or more complex tears is needed. In most cases, physical therapy is essential in restoring strength and range of motion while the exact approach depends on the extent of the tear.

Non-surgical recovery for rotator cuff injuries takes approximately several weeks to a few months. Conversely, recovery from surgery can take anywhere from 4 to 6 months, with full strength returning only after about a year.

Depending on the severity of the injury and treatment necessary for recovery, estimated medical costs for rotator cuff injuries range from a few hundred dollars for non-surgical treatment to over $10,000 for surgery, depending on the location, complexity, and healthcare provider selected.

If left untreated, improperly healed rotator cuff tears can lead to permanent pain, weakness, decreased joint function, or detrimental degenerative changes like arthritis.

Rotator cuff issues amount to more than 4.5 million physician visits annually in the United States, and tears become more common as age advances. To prevent the possibility of a potential rotator cuff injury, it’s recommended to use proper techniques during physical activity, avoid excessive strain, and keep up with regular strength training and flexibility exercises.

What is a Shoulder Fracture?

A fracture refers to a break in a bone, and for the shoulder, that means one of three main bones that comprise the area: the collarbone (clavicle), the upper arm bone (humerus), or the shoulder blade (scapula), all of which work together to allow for a wide range of arm motions while providing structural support. Current statistics show that the clavicle is the most common shoulder bone inured, accounting for about 5% of all adult fractures.

Shoulder fractures usually occur as a result of direct trauma, a fall onto an outstretched arm, or a high-energy collision like a car accident. For the latter, shoulder fractures can be caused by the sheer force of the crash itself, especially if the shoulder strikes a hard object like the car door, window, or steering wheel. Additionally, the abrupt restraint by the seatbelt, coupled with the body’s forward momentum during a collision, can sometimes exert enough force on the shoulder region to result in a fracture.

High-speed collisions, improper seatbelt usage, and pre-existing bone conditions like osteoporosis all increase the risk of shoulder fractures. Pain, swelling, bruising, deformity, limited shoulder movement, and in some cases, a grinding sensation, can all hint at the underlying issue, but a physical examination followed by imaging tests such as X-rays, CT scans, or MRI will be needed to determine the fracture’s exact location and severity.

Depending on the specifics of shoulder fracture, treatment can range from simple immobilization using a sling or brace to surgical intervention for realigning and securing bone fragments. Orthopedic surgeons and trauma surgeons can address shoulder fractures, while physical therapists are essential in assisting in the post-injury rehabilitation process.

Physical therapy itself is an important part of the recovery and rehabilitation process, as it can help restore range of motion and strength when combined with rest. Of course, rehabilitation varies based on the fracture’s severity and the treatment approach.

Often, the recovery time for a non-displaced shoulder fracture to heal is roughly 6-8 weeks, while more severe fractures or ones that require surgery may need several months for complete recovery.

Of course, the average medical cost of treating a shoulder fracture varies according to the severity of the injury. It’s reasonable to expect an expense ranging from a few hundred to over a thousand dollars for non-surgical treatment options, to $10,000 or more for surgery, depending on complexity and healthcare providers.

If a shoulder fracture isn’t treated properly, complications can arise such as chronic pain, decreased shoulder mobility, or post-traumatic arthritis. Fortunately, advancements in surgical techniques can minimize invasiveness and optimize outcomes for those who seek treatment.

To prevent the chances of a shoulder fracture, it’s important to always wear a seatbelt, keep car safety features in proper working order, and maintain bone health through diet and exercise.

What is a Brachial Plexus Injury?

A Brachial Plexus Injury (BPI) refers to damage to the brachial plexus, a network of nerves that transmit signals from the neck’s spinal cord (C5-C8 and T1) to the arm, shoulder, and hand. The intricate nerve bundle is fragile, and can easily be stretched, compressed, or torn due to sudden trauma.

In the case of a car accident, a Brachial Plexus Injury can occur when there’s a forceful impact that causes the shoulder to be violently pushed downward while the neck tilts to the opposite side, such as in a side-impact collision or rollover. This kind of sharp motion can stretch or rupture the BPI nerves, or even detach them from the spinal cord, and lead to various degrees of dysfunction in the affected limb including weakness, numbness, severe pain, diminished reflexes, or complete paralysis of the affected arm.

High-speed collisions, ejections from the vehicle, motorbike accidents, and failure to use or improper use of seatbelts, all increase the chances of sustaining a Brachial Plexus Injury.

Along with specialized imaging studies like MRI or CT myelogram, and electrophysiological studies like electromyography (EMG), Brachial Plexus Injuries are diagnosed via clinical examinations from neurologists, neurosurgeons, orthopedic surgeons, although physical therapists play roles in diagnosing and treating Brachial Plexus Injuries, too.

Mild Brachial Plexus Injuries can resolve in mere weeks to months, while more severe BPIs may take months or years to heal, with some patients never fully recovering even with intervention; severe nerve injuries can lead to permanent disability, chronic pain, and muscle atrophy.

Depending on the severity, treatment may include pain management medication, physical therapy, nerve grafts, nerve transfers, or muscle transfers. In all cases of BPI, physical therapy is essential in preventing joint stiffness and regaining function, but the rehabilitation’s exact duration and success depend on the injury’s extent and treatment.

Due to the incredibly complex nature of nerves, more specialized surgeries to repair damage to the Brachial Plexus may result in medical expenses costing tens of thousands of dollars, while less severe issues may only cost a few thousand to treat.

Advances in microsurgical techniques have improved outcomes for nerve grafting and transfers, and studies on nerve growth factors and regenerative medicine hold promise for future treatments. All of this is good news for people who suffer from BPIs, as Brachial Plexus Injuries account for approximately 5% of all traumatic injuries of peripheral nerves and are often seen in car accident victims.

To reduce the risk of sustaining a Brachial Plexus Injuries, always be sure to properly use seatbelts and protective gear (for motorcyclists or bicyclists), practice safe driving, and make sure your vehicle has the latest safety features!

What is Tendonitis and Bursitis in the Shoulder?

Tendonitis (sometimes also spelled tendinitis) and bursitis in the shoulder both refer to inflammation of specific structures within the joint itself.

Tendonitis refers to inflammation of the tendons, fibrous cords attaching muscles to bones. In the shoulder, this is often the four tendons of the rotator cuff which stabilize and mobilize the shoulder joint. Bursitis, meanwhile, refers to inflammation of the bursa, which is a small fluid-filled sac that acts as a cushion to reduce friction between the bones and soft tissues.

In a car accident, the sudden and forceful impact or jolt, such as when a person’s shoulder is slammed against the door or restrained abruptly by the seatbelt, can strain the tendons and cause inflammation, which then leads to tendinitis. Similarly, trauma from a car accident can irritate or compress the delicate bursae, resulting in bursitis.

Diagnosing tendinitis or bursitis involves a clinical examination from an orthopedic surgeon, rheumatologist, physical therapist, or sports medicine specialist, and imaging tests like X-rays, MRI, or ultrasound can confirm, while pain (often worsened with movement or at night), swelling, limited range of motion, and tenderness are all common symptoms of both conditions.

Non-surgical treatment options for tendonitis and bursitis commonly include rest, ice, nonsteroidal anti-inflammatory drugs (NSAIDs), physical therapy to aid in restoring motion and strength, or corticosteroid injections, although some persistent cases may require surgery. Similarly, current research has supported the effectiveness of regenerative treatments such as platelet-rich plasma (PRP) injections to help heal tendinitis.

Depending on the severity of the issue and which treatment is needed, the medical costs of tendonitis and bursitis can range from a conservative few hundred dollars for medication and physical therapy, to a few thousand dollars for injections, to $10,000 or more for surgery.

The recovery time for tendonitis and bursitis varies depending on several factors, but most patients see improvement in weeks to a few months unless surgical intervention is needed and the recovery period is lengthened as a result. It’s important to remember, though, that previous shoulder injuries, pre-existing inflammatory conditions, age, and abrupt high-impact trauma – like a car accident – all contribute to higher risk factors of contracting tendinitis or bursitis.

Chronic tendinitis, or recurrent bursitis, might lead to a reduced range of motion, persistent pain, or degenerative changes in the shoulder, so it’s important to try and prevent these injuries. With millions of cases reported annually in the United States, it’s unknown how many are caused by car accidents, but tendinitis and bursitis are extremely common shoulder ailments!

What is Thoracic Outlet Syndrome (TOS)?

Compression of the blood vessels or nerves situated between the collarbone (clavicle) and the first rib, in a narrow area called the thoracic outlet, causes a condition called Thoracic Outlet Syndrome (TOS). This area contains vital neurovascular structures, including parts of the brachial plexus (nerves) and the subclavian artery and vein, which serve the arm and hand, and compression from TOS often manifests in pain in the neck and shoulder, numbness and tingling in the fingers, a weakened grip, and sometimes discoloration or swelling in the arm.

After the trauma of a car accident, TOS can develop from the resulting inflammation, scar tissue formation, or from direct injury to the structures of the thoracic outlet. Sharp and sudden impacts from airbag deployments or seatbelt restraints can displace or injure the clavicle or other structures which can then contribute to compression and symptoms of TOS.

Prior neck or shoulder injuries increase the risk of TOS, while anatomical variations (like an extra rib) and high-impact collisions are also risk factors. However, making sure to properly use seatbelts, driving safely, and strengthening and stretching exercises for the neck and shoulders can help reduce those risks!

Thoracic Outlet Syndrome is usually diagnosed by vascular surgeons, neurologists, or orthopedic surgeons with a clinical examination, imaging studies (like X-rays or MRI), and specialized tests such as nerve conduction studies, but physical therapists also play a role in diagnosing and treating TOS.

Despite precise statistics on TOS from car accidents being tough to pinpoint, car accidents are a known traumatic cause of the condition. For people who suffer from Thoracic Outlet Syndrome, the recommended course of treatment is generally physical therapy, pain relief medications, anti-inflammatory drugs, lifestyle changes, and, in severe cases, surgical decompression of the nerves or blood vessels in the thoracic outlet.

The TOS recovery and rehabilitation process focuses on strengthening and stretching exercises with physical therapy, but recovery can range from weeks to months, depending on severity.

Mild cases of TOS can resolve in as little as a few weeks with proper management, but severe or surgical cases can take several months. In terms of costs, this means conservative treatments might only be a few hundred or a couple thousand dollars, but surgery can cost upwards of $10,000 or more depending on the procedure and aftercare.

It’s important not to ignore the signs of TOS, though, since untreated or chronic Thoracic Outlet Syndrome can lead to permanent nerve damage, chronic pain, or dangerous circulatory issues!

Fortunately, studies are being done on refining optimal surgical techniques in addition to enhancing the efficacy of non-surgical treatments, and developing better diagnostic criteria.

What is Frozen Shoulder or Adhesive Capsulitis?

The medical term “adhesive capsulitis” is more commonly called “frozen shoulder” and refers to a condition where the shoulder joint becomes stiff and painful, resulting in limited range of motion. It’s characterized by the thickening and tightening of the shoulder capsule, which is the connective tissue surrounding the joint.

After a car accident, either direct trauma to the shoulder or prolonged immobilization to other injuries can cause a frozen shoulder. The inflammation and scar tissue formation from the trauma can further restrict the joint’s movement, and if the shoulder isn’t moved regularly post-accident due to pain or fear, adhesive capsulitis can develop and intensify.

The shoulder’s ball-and-socket joint includes the head of the humerus (arm bone) and the glenoid cavity of the scapula (shoulder blade), and it’s all encased in a capsule of connective tissue. People of older ages, who have pre-existing shoulder conditions, or who suffer from prolonged post-accident immobilization, diabetes, or thyroid issues, have a higher risk of developing a frozen shoulder.

While exact figures attributing frozen shoulder to car accidents aren’t readily available, it’s estimated that approximately 2-5% of the general population experience adhesive capsulitis at some point in their lives.

Frozen shoulder isn’t always obvious, but the gradual onset of pain, worsening shoulder stiffness, difficulty in sleeping due to pain, and limited shoulder mobility all hint at the underlying condition. To appropriately diagnose, it’s necessary to undergo a clinical examination by an orthopedic surgeon, rheumatologist, physical therapist, or sports medicine specialist, and use imaging tests like X-rays or MRI to rule out other issues.

Once frozen shoulder is confirmed, physical therapy can be crucial as the focus on stretching and strengthening exercises can help during the recovery process which typically happens in phases (freezing, frozen, thawing) over the course of 12-18 months; if left untreated, the condition can lead to prolonged pain and permanent range-of-motion limitations.

After a car accident or trauma, it’s important to follow a medical professional’s guidelines for early mobilization, physical therapy, or regular shoulder exercises to help prevent stiffness.

Pain relief medications, physical therapy, nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroid injections, joint distension, and in severe cases, surgery, have all proven to be effective treatment options for frozen shoulder.

Conservative treatments for the condition often range from a few hundred to a couple of thousand dollars in medical care costs. When needed, surgical treatments for frozen shoulder can significantly elevate costs, sometimes exceeding $10,000.
