Back Clinic Complex Injuries Chiropractic Team. Complex injuries happen when people experience severe or catastrophic injuries, or whose cases are more complex due to multiple trauma, psychological effects, and pre-existing medical histories. Complex injuries can be serial injuries of the upper extremity, severe soft tissue trauma, and concomitant (naturally accompanying or associated), injuries to vessels or nerves. These injuries go beyond the common sprain and strain and require a deeper level of assessment that may not be easily apparent.

Can physical therapy treatment protocols aimed at improving range of motion and flexibility around the hip and relieving inflammation around the sciatic nerve help individuals experiencing deep buttock pain or piriformis syndrome?
Deep Buttock Pain
Piriformis syndrome, a.k .a. deep buttock pain, is described as sciatic nerve irritation from the piriformis muscle.
The piriformis is a small muscle behind the hip joint in the buttocks.
It is about one centimeter in diameter and functions in the hip joint’s external rotation or turning outward.
The piriformis muscle and tendon are close to the sciatic nerve, which supplies the lower extremities with motor and sensory functions.
Depending on an individual’s anatomic variation of the muscle and tendon:
The two cross over, under, or through each other behind the hip joint in the deep buttock.
This relationship is thought to irritate the nerve, leading to sciatica symptoms.
Piriformis Syndrome
When diagnosed with piriformis syndrome, it is thought that the muscle and tendon bind to and/or spasm around the nerve, causing irritation and pain symptoms.
The theory supported is that when the piriformis muscle and its tendon tighten, the sciatic nerve becomes compressed or pinched. This decreases blood circulation and irritates the nerve from the pressure. (Shane P. Cass 2015)
Tenderness with pressure on the piriformis muscle.
Discomfort in the back of the thigh.
Deep buttock pain behind the hip.
Electric sensations, shocks, and pains travel down the back of the lower extremity.
Numbness in the lower extremity.
Some individuals develop symptoms abruptly, while others go through a gradual increase.
Diagnosis
Doctors will order X-rays, MRIs, and nerve conduction studies, which is normal.
Because piriformis syndrome can be challenging to diagnose, some individuals with minor hip pain may receive a piriformis syndrome diagnosis even if they don’t have the condition. (Shane P. Cass 2015)
It is sometimes referred to as deep buttock pain. Other causes of this type of pain include back and spinal problems like:
Herniated discs
Spinal stenosis
Radiculopathy – sciatica
Hip bursitis
A piriformis syndrome diagnosis is usually given when these other causes are eliminated.
When the diagnosis is uncertain, an injection is administered in the area of the piriformis muscle. (Danilo Jankovic et al., 2013)
Different medications can be used, but the injection itself is used to help determine the specific location of the discomfort.
When an injection is given into the piriformis muscle or tendon, it is often administered by ultrasound guidance to ensure the needle delivers the medication to the correct location. (Elizabeth A. Bardowski, J. W. Thomas Byrd 2019)
Avoiding activities that cause symptoms for at least a few weeks.
Physical Therapy
Emphasize stretching and strengthening the hip rotator muscles.
Non-Surgical Decompression
Gently pulls the spine to release any compression, allowing optimal rehydration and circulation and taking the pressure off the sciatic nerve.
Therapeutic Massage Techniques
To relax and release muscle tension and increase circulation.
Acupuncture
To help relax the piriformis muscle, sciatic nerve, and surrounding area.
Relieve pain.
Chiropractic Adjustments
Realignment rebalances the spine and musculoskeletal system to alleviate pain.
Anti-Inflammatory Medication
To decrease inflammation around the tendon.
Cortisone Injections
Injections are used to decrease inflammation and swelling.
Botulinum Toxin Injection
Injections of botulinum toxin paralyze the muscle to relieve pain.
Surgery
Surgery can be performed in rare cases to loosen the piriformis tendon, known as a piriformis release. (Shane P. Cass 2015)
Surgery is a last resort when conservative treatments have been tried for at least 6 months with little to no relief.
Recovery can take several months.

Knee injuries can present in physically active individuals that lift weights. Can understanding the types of weightlifting knee injuries help in prevention?
Weightlifting Knee Injuries
Weight training is very safe for the knees as regular weight training can improve knee strength and prevent injury as long as the correct form is followed. For Individuals with knee injuries from other activities, incorrect weight-training exercises could worsen the injury. (Ulrika Aasa et al., 2017) As well as, sudden twisting movements, poor alignment, and pre-existing injuries can increase the risk of worsening or creating further injuries. (Hagen Hartmann et al, 2013) The body and the knees are designed to support vertical forces on the joints.
Common Injuries
Weightlifting knee injuries occur as the knee joints endure a wide range of stresses and strains. In weight training, the ligaments that attach to the complex bone system of the knee joint can be damaged by incorrect movements, overloading the weight, and increasing the weight too soon. These injuries can result in pain, swelling, and immobility that can range from minor to severe, from a sprain or a slight tear to a complete tear in serious cases.
Anterior Cruciate Ligament – ACL – Injury
This ligament attaches the thigh’s femur bone to the lower leg’s shin bone/tibia and controls excessive rotation or extension of the knee joint. (American Academy of Family Physicians. 2024)
Anterior means front.
ACL injuries are seen mostly in athletes but can happen to anybody.
Severe damage to the ACL usually means surgical reconstruction and up to 12 months of rehabilitation.
When weightlifting, try to avoid twisting knee movements, intentionally or accidentally, under excessive load.
Posterior Cruciate Ligament – PCL – Injury
The PCL connects the femur and tibia at different points to the ACL.
It controls any backward motion of the tibia at the joint.
Injuries occur most with high-impact forces as a result of accidents and sometimes in activities where forceful trauma to the knee occurs.
Medial Collateral Ligament – MCL – Injury
This ligament maintains the knee from bending too far to the inside/medially.
Injuries mostly occur from impact to the outside of the knee or from accidental bodyweight force on the leg that bends at an unusual angle.
Lateral Collateral Ligament – LCL – Injury
This ligament connects the smaller bone of the lower leg/fibula to the femur.
It is opposite to the MCL.
It maintains excessive outward movement.
LCL injuries occur when a force pushes the knee out.
Cartilage Injury
Cartilage prevents bones from rubbing together and cushions impact forces.
Knee menisci are cartilage that cushions the knee joints inside and outside.
Other types of cartilage protect the thigh and shin bones.
When cartilage gets torn or damaged, surgery may be required.
Tendonitis
Aggravated and overused knee tendons can lead to weightlifting knee injuries.
A related injury known as iliotibial band syndrome/ITB causes pain to the outside of the knee, usually in runners, but it can occur from overuse.
Rest, stretching, physical therapy, and anti-inflammatory medication are a common treatment plan.
The condition causes the cartilage to deteriorate and bones to rub together, resulting in pain and stiffness.
Prevention
Individuals can minimize their risk of weightlifting knee injuries and pain by following their doctor’s and personal trainers’ recommendations.
Individuals with an existing knee injury should follow their doctor’s or physical therapist’s recommendations.
A knee sleeve can keep the muscles and joints secure, providing protection and support.
Stretching the leg and knee muscles can maintain joint flexibility.
Avoid sudden lateral movements.
Possible recommendations can include:
Avoiding Certain Exercises
Isolation exercises like leg curls, standing, or on a bench, as well as using the leg extension machine, can stress the knee.
Deep Squat Training
Research shows that the deep squat can protect against lower leg injury if the knee is healthy. However, this is when done with proper technique, under expert supervision, and with a gradual progressive load. (Hagen Hartmann et al, 2013)
Individuals should talk to their doctor before beginning a new exercise routine. A personal trainer can provide training in learning the proper technique and weightlifting form.

Individuals that engage in heavy exercise can develop heat cramps from overexertion. Can knowing the causes and symptoms help prevent future episodes from happening?
Heat Cramps
Heat cramps can develop during exercise from overexertion or prolonged exposure to high temperatures. The muscle cramps, spasms, and pain can range from mild to severe.
Electrolytes like sodium, calcium, and magnesium are important for properly functioning muscles, including the heart. The primary role of sweating is to regulate the body’s temperature. (MedlinePlus. 2015) Sweat is mostly water, electrolytes, and sodium. Excessive sweating from physical activity and exertion or a hot environment can cause electrolyte imbalances that lead to cramps, spasms, and other symptoms.
Causes and Activities
Heat cramps most commonly affect individuals who sweat excessively during strenuous activity or are exposed to hot temperatures for prolonged periods. The body and organs need to cool down, which causes sweat production. However, too much sweating can lead to dehydration and electrolyte depletion. (Centers for Disease Control and Prevention. 2022)
Age – Children and adults 65 years and older have the highest risk.
Excessive sweating.
Low sodium diet.
Preexisting Medical Conditions – heart disease, diabetes mellitus, and obesity are conditions that can increase the risk of muscle cramping.
Medications – blood pressure, diuretics, and antidepressants can affect electrolyte balance and hydration.
Alcohol consumption.
Self-Care
If heat cramps begin, immediately stop the activity and look for a cool environment. Rehydrate the body to replenish the fluid loss. Staying hydrated and drinking fluids regularly during intense activity or in a hot environment can help prevent the body from cramping. examples of beverages that increase electrolytes include:
Gently applying pressure and massaging affected muscles can help reduce pain and spasms. As symptoms resolve, it is recommended to not return to strenuous activity too soon because additional exertion can progressively lead to heatstroke or heat exhaustion. (Centers for Disease Control and Prevention. 2021) Heatstroke and heat exhaustion are two heat-related illnesses. (Centers for Disease Control and Prevention. 2022)
Heatstroke is when the body loses the ability to regulate temperature and can cause dangerously high temperatures.
Heat exhaustion is the body’s response to excessive fluid and electrolyte loss.
The majority of heat cramps develop during activities because of the exertion and sweating, causing more electrolytes to be lost and the body to become more dehydrated.
Symptoms can also develop minutes to hours after activity has ceased.
Duration
Most heat-related muscle cramps will resolve with rest and hydration within 30–60 minutes.
If muscle cramping or spasms do not subside within one hour, seek professional medical attention.
For individuals with heart conditions or on a low-sodium diet who develop heat cramps, regardless of duration, medical help is necessary to ensure there are no complications.
Finger sprains and dislocations are common hand injuries that can happen during work, physical/sports activities, or in automobile collisions and accidents. Can recognizing the symptoms help in developing an effective treatment strategy?
Finger Sprains and Dislocations
Finger sprains and dislocations are common injuries of the hand that cause pain and swelling.
A sprain happens when the finger tissue that supports a joint gets stretched beyond its limits in a way that stresses the ligaments and tendons.
The ligament tissue can be partially or completely torn. If the damage is bad enough, the joint comes apart.
This is a dislocation – A dislocation happens when the joint in the finger gets shifted out of its normal position.
Both injuries can cause pain and stiffness in the finger and hand.
Sprains
Finger sprains can happen any time the finger bends in an awkward or unusual way. This can happen from falling on the hand or getting hurt when engaged in physical activities like sports or household chores. Sprains can occur in any of the knuckle joints in the finger. However, most commonly, the joint in the middle of the finger gets sprained. It’s known as the proximal interphalangeal or PIP joint. (John Elfar, Tobias Mann. 2013) Symptoms of a finger sprain can include:
Other treatments to help a sprained finger include:
Elevate the hand if swelling and inflamed.
Gentle finger exercises/movements to prevent stiffness.
Icing the injured finger.
Take an anti-inflammatory medication.
Individuals who have not broken bones or dislocated the joint will probably be able to move their finger in about a week. A doctor will set a timeline for when to start using the finger normally.
Individuals who sprain their finger that feels swollen and stiff for longer than a few weeks are recommended to consult a doctor or specialist.
Thumb sprains and finger sprains in children may need to be splinted or taped for longer periods, as the ligament is not fully developed or as strong, which could lead to a tear.
Dislocations
A finger dislocation is a more severe injury involving the ligament, joint capsule, cartilage, and other tissues that causes misalignment of the finger. The ligaments and the joint capsule get torn when a joint is dislocated. The joint needs to be reset, which can be a simple process, or in severe cases, patients may need to be placed under anesthesia or undergo surgery to reset the joint properly.
In these cases, tendons or other tissues might be preventing the joint from getting into position.
Putting the finger back into the right position is known as”reduction.” Once reduced, the finger needs to be splinted.
Individuals also need an X-ray to ensure the joint is lined up correctly and that any bones were not broken or fractured when they sustained the injury. (James R. Borchers, Thomas M. Best. 2012)
Once reset, caring for a dislocated finger is basically the same as a sprained finger. Using ice on the finger, keeping the hand elevated to reduce swelling.

Individuals suffering from hip, thigh, and/or groin pain could be experiencing iliopsoas syndrome. Could knowing the symptoms and causes help in diagnosis and treatment?
Iliopsoas Syndrome
Iliopsoas syndrome encompasses several conditions that affect the inner hip muscle and can cause hip and thigh pain. The muscle helps to bend the leg toward the body.
The condition is usually caused by overuse injuries and commonly affects individuals who perform repeated hip flexion movements, like cyclists, gymnasts, dancers, runners, and soccer players. (Liran Lifshitz, et al., 2020)
The term is often used interchangeably with psoas syndrome, iliopsoas tendonitis, snapping hip syndrome, and iliopsoas bursitis. However, there are clinical differences.
Hip or groin clicking or snapping that can be heard and/or felt during movement.
Pain and/or stiffness in the hip and thigh area.
Pain that worsens when bending the hip – walking, climbing stairs, squatting, sitting.
Movements that involve bringing the knee toward the chest can worsen the pain.
Causes
The iliopsoas muscles are hip muscles on the front of the hip. They are made up of the psoas major, the psoas minor, and the iliacus. Small, fluid-filled sacs/bursae are within the hip joint between bones and soft tissues. The bursae reduce friction and provide cushioning to help the tendons, muscles, and other structures move smoothly over the bony prominences.
Iliopsoas bursitis happens when the bursa, which is located between the iliopsoas tendon and the inside of the hip joint, becomes inflamed and irritated.
Iliopsoas tendonitis/hip tendonitis happens when the tendon that attaches the thigh bone to the iliopsoas muscle becomes inflamed and irritated.
Iliopsoas bursitis and tendonitis are commonly caused by overuse injuries and intense activities like cycling, running, rowing, or strength training.
Diagnosis
Healthcare providers can diagnose iliopsoas syndrome based on symptom history and a hip examination.
Imaging tests – MRI and X-rays may be used to rule out other injuries or conditions like muscle tears. (Paul Walker, et al., 2021)
Avoid putting weight on the hip for a few days after the injury.
Ice
Apply ice immediately after the injury to bring the swelling down.
Use a cold pack for 20 minutes at a time, several times a day.
Do not apply ice directly on the skin.
Compression
Wrap the area in a soft bandage or use compression shorts to prevent further swelling.
Elevation
Rest as often as possible with the leg raised higher than the heart.
Medical Treatment
Non-steroidal anti-inflammatory drugs like ibuprofen and naproxen sodium can alleviate pain and reduce inflammation. (Paul Walker, et al., 2021)
Steroid injections can be used if symptoms continue or come back with additional injections administered as necessary. (Paul Walker, et al., 2021)
After pain and swelling subside, physical therapy may be recommended, as well as mild exercises to gradually improve hip strength and flexibility. (Paul Walker, et al., 2021)
A healthcare provider may recommend surgery in severe cases where pain persists, and conservative treatments don’t provide enough relief.

Hamstring muscle injuries are common, especially in athletes and individuals with physically demanding jobs. Is there a better chance of full recovery with surgical repair and post-op rehabilitation?
Hamstring Muscle Tear
Most often, hamstring muscle injuries are partial tears of the muscle. These types of injuries are muscle strains that occur when the muscle fibers are stretched beyond their normal limits. Complete tears of the hamstring muscle are unusual, but they do occur in both athletes and non-athletes. Determining the optimal treatment plan depends on:
The severity of the tendon tear
The expectations of the injured individual.
Incomplete tears are when the hamstring muscle is stretched too far, but not completely detached.
Complete tears usually occur at the top of the muscle where the tendon tears away from the pelvis.
A complete tear usually occurs when there is a sudden flexion of the hip and extension of the knee joint – when the muscle contracts in this position, it gets stretched beyond its limits.
Basic hamstring strains can be treated with simple steps – rest, ice, anti-inflammatory medications, and conservative therapies.
Symptoms
Symptoms of a hamstring muscle strain can include pain, bruising, swelling, and movement difficulty. (American Academy of Orthopaedic Surgeons. 2021) Individuals who sustain this injury typically experience sudden sharp pain. Signs of a tear can include:
Sharp pain where the buttock and thigh meet.
Difficulty walking.
Sitting can be difficult as the edge of a chair can place pressure directly on the injury.
Spasms and cramping sensations in the back of the thigh.
Weakness in the leg, specifically when bending the knee or lifting the leg behind the body.
Numbness or burning sensations as a result of sciatic nerve irritation.
Swelling and bruising in the back of the thigh – over time it can travel down to the back of the knee and calf and possibly into the foot.
With a complete hamstring tear, there is usually significant swelling and bruising that develops in the back of the thigh.
Diagnosis
The symptoms can be difficult to spot in the early stages which is why X-rays of the hip or thigh are usually obtained.
In some situations, a fragment of bone can get pulled off the pelvis along with the hamstring muscle attachment. MRI testing can be performed to evaluate the attachment and can define critical features of a complete hamstring muscle tear, including: (American Academy of Orthopaedic Surgeons. 2021)
The number of tendons involved.
Complete versus incomplete tearing.
The amount of retraction – the amount the tendons have pulled back.
This will guide the development of treatment.
Treatment
The treatment of a complete tear will depend on different factors. The other variable is the patient and their expectations.
Treatment is more aggressive in younger individuals like high-level athletes.
Treatment is less aggressive in middle-aged individuals.
Often a single tendon tear can be treated non-surgically.
When one tendon is involved, it is typically not pulled very far from its normal attachment and will develop scar tissue in a positive position.
Conversely, when three tendons have been torn, they usually pull more than a few centimeters away from the bone. These cases have better results with surgical repair. (UW Health. 2017)
Surgeons will use patient characteristics – high-level athletes or less physically active individuals – to guide treatment recommendations.
Rehabilitation
Rehabilitation following surgery can take 3-6 months or longer.
The first six weeks limit weight-bearing with the use of crutches.
Patients may be recommended to wear a brace to reduce tension on the repaired hamstring tendons.
Strengthening does not begin until three months post-op, and even light activities are usually delayed. (UW Health. 2017)
Because this injury can have a long recovery time, some individuals may choose nonsurgical treatment.
Sometimes these individuals experience symptoms of discomfort from sitting and may exhibit long-term weakness of the hamstring muscle.
Full recovery from a complete hamstring muscle injury takes time. Studies have shown high-level athletes are able to resume competitive sports after the repair and rehabilitation of an acute hamstring muscle injury. (Samuel K. Chu, Monica E. Rho. 2016)
Delaying surgical treatment may not always lead to optimal results.
When the tendon is torn away from its normal attachment, it begins to scar around the surrounding soft tissues.
When there is a delay of more than a few weeks following the initial injury, regaining the full length of the tendon and muscle can be challenging.
This could delay the rehabilitation process and may limit the potential for full recovery. (Ho Yoon Kwak, et al., 2011)
With severe injuries, there is a better chance of full recovery with surgical repair but could involve a long recovery and commitment to a post-op rehabilitation plan.

As the body ages, individuals want to stay active and maintain a healthy pain free lifestyle. Can regenerative cells for arthritis and cartilage damage be the future of neuromusculoskeletal medicine and joint healing?
Regenerative Cells For Arthritis and Cartilage Damage
Individuals want to continue to do the physical activities they love, which require healthy joints. Scientists are learning how to harness the abilities of regenerative cells to repair and regrow damaged and deteriorated cartilage. Current stem cell treatment of cartilage problems has not been shown to reverse the effects of arthritis and while studies show clinical improvement, further research is necessary. (Bryan M. Saltzman, et al., 2016)
Cartilage and How It Gets Damaged
Cartilage is a type of connective tissue. In the joints, there are a few types of cartilage. The most commonly referred to is the smooth lining known as articular or hyaline cartilage. This type forms a smooth layer of cushion on the end of a bone at the joint. (Rocky S. Tuan, et al., 2013)
The tissue is very strong and has the ability to compress and absorb energy.
It is very smooth allowing a joint to glide effortlessly through a limb’s range of motion.
When joint cartilage is damaged, the cushioning can wear down.
In traumatic injuries, a sudden force can cause the cartilage to break off and/or suffer damage, that exposes the underlying bone.
In osteoarthritis – degenerative or wear-and-tear arthritis, the smooth layer can wear down thin and unevenly.
Eventually, the cushion wears away, the joints become inflamed and swollen and movements become stiff and painful.
There are treatments for arthritis and cartilage damage, but these treatments are usually focused on relieving symptoms by smoothing down the damaged cartilage or replacing the joint surface with an artificial implant, like knee replacement or hip replacement surgeries. (Robert F. LaPrade, et al., 2016)
Regenerative Cells
Regenerative stem cells are special cells that have the ability to multiply and develop into different types of tissue. In an orthopedic surgery setting for joint problems, stem cells are obtained from adult stem cell primary sources which are bone marrow and fatty tissue. These cells have the ability to develop into cartilage cells, called chondrocytes. (Rocky S. Tuan, et al., 2013)
They also help by stimulating the body to reduce inflammation, stimulate cell repair, and improve blood circulation.
This process is caused by cellular signals and growth factors to stimulate the body to activate the healing processes.
Once stem cells have been obtained, they need to be delivered to the area of cartilage damage.
Cartilage is a complex tissue that is described as a scaffold structure that is composed of collagen, proteoglycans, water, and cells. (Rocky S. Tuan, et al., 2013)
To regenerate cartilage, the complex tissues must also be reconstructed.
There are studies on types of tissue scaffolds engineered to recreate a similar type of cartilage structure.
The stem cells can then be injected into the scaffold, in hopes of restoring a normal type of cartilage.
Non-Surgical Arthritis Treatments
Standard treatments such as cortisone shots or physical therapies work as well and provide benefits that could be utilized in combination with regenerative cells for arthritis and cartilage damage in the near future. Data takes time and therefore how this impacts the long-term health of a joint needs continued research in terms of tissue engineering and cell delivery to determine the best approach to help individuals.
