Calcification is a process where calcium builds up in areas of body tissue where it doesn't normally exist. Calcification of muscles, also known as myositis ossificans, is a rare condition characterized by the abnormal formation of bone within muscle tissue. It is usually caused by trauma or injury to the affected area, such as a deep muscle bruise or repetitive muscle injury. Calcification can also be caused by autoimmune disorders such as dermatomyositis, which results in prominent calcifications in the muscles of the upper arms and legs. Patients with severe injuries, such as level 1 trauma or burns, often face complications of calcification during recovery, including loss of bone and calcification of soft tissue.

Calcification is the body's response to inflammation, injury, or certain biological processes
Calcification can be identified through a biopsy, which collects a tissue sample for testing. If no cancer cells are found, the calcification is labelled as benign. Calcification can be harmful when it disrupts organ function and affects blood vessels. For example, heart valves can develop calcifications that may require surgery if the buildup is severe enough to affect the valve's function.
In some cases, calcification can be beneficial. For instance, plasmin, a protease known for its clot-busting role in the blood, can prevent muscle 'hardening' and protect soft tissue from turning to bone after severe injuries. Researchers have found that plasmin is required to prevent calcification and heterotopic ossification after acute muscle injury.
Calcification can also be influenced by certain biological processes. For instance, bone morphogenetic protein (BMP) is a factor that promotes bone formation and may contribute to trauma-induced muscle calcification. However, attempts to stop bone formation by blocking BMP could potentially harm the bones. Therefore, the ideal treatment would be one that prevents calcification in soft tissue while also being beneficial for bone biology.

Calcification can lead to organ failure and disrupt blood vessels
Calcification is a buildup of calcium in body tissue, blood vessels, or organs. This buildup can form hardened deposits in soft tissues, arteries, and other areas. Calcification can occur in almost any part of the body. It is believed to be the body's response to inflammation, injury, or certain biological processes.
Calcification can also cause loss of bone or osteoporosis. It can lead to heterotopic ossification, which is the presence of bone in soft tissue where bone does not normally exist. Calcification can interfere with motion and respiration and can be lethal at an early age.
Vanderbilt researchers have found that severe injuries can trigger systemic inflammatory response syndrome, resulting in organ failure. Calcification can also cause pain and limit mobility.

Heterotopic ossification is the presence of bone in soft tissue where it does not normally exist
Heterotopic ossification (HO) is the presence of bone in soft tissue where it does not normally exist. It is a condition where bone tissue develops in soft tissues, and it often occurs after an injury or major surgery. It can also be caused by autoimmune disorders such as CREST syndrome or dermatomyositis, or as a complication of closed head injury, paraplegia, or quadriplegia. In rare cases, it can be genetic and congenital, interfering with motion and respiration and leading to early death.
HO can develop in anyone, but certain patients, such as those with ankylosing spondylitis or diffuse idiopathic skeletal hyperostosis, are more prone to it. It is twice as common in males than in females, although older females (over 65) have an increased risk. It is also commonly seen in patients with burns, strokes, spinal cord injuries, amputations, joint replacements, and traumatic brain injuries.
The condition can range from small, clinically insignificant foci of ossification to large deposits of bone that cause pain and restrict movement. The most common symptom is pain around the ossification site, along with soft tissue swelling, fever, and poor mobility of the affected joint.
HO is diagnosed when soft tissue ossification with a sharp demarcation from the surrounding soft tissues is seen on a radiograph or an MRI scan. Treatment options include medications such as NSAIDs and corticosteroids, physical therapy, and, in some cases, surgery.

Calcification can be caused by autoimmune disorders such as dermatomyositis and CREST syndrome
Calcification occurs when calcium builds up in areas of body tissue where calcium does not normally exist. Calcification can be caused by autoimmune disorders such as dermatomyositis and CREST syndrome.
Dermatomyositis is an autoimmune disorder that can cause soft tissue calcification. It is a type of connective tissue disease that results in inflammation and calcification of the muscles, most prominently in the upper arms and legs. This inflammation and calcification can lead to pain, limited mobility, and reduced muscle function.
CREST syndrome, also known as Cutaneous Systemic Sclerosis or Limited Scleroderma, is an autoimmune disease characterised by calcinosis, Raynaud's phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasia. Calcinosis is the pathologic calcification of soft tissues, leading to the deposition of calcium salts into the skin and subcutaneous tissue. This can cause pain, tenderness, ulceration, and secondary infection at the site of calcification. CREST syndrome is a subtype of progressive systemic sclerosis (SSc) and occurs in approximately 22-25% of all cases.
Both dermatomyositis and CREST syndrome can result in calcification of soft tissues, including muscles. This calcification is believed to occur due to chronic stress, local trauma, or underlying inflammatory processes associated with these autoimmune disorders. The exact cause of CREST syndrome is not fully understood, but it is thought to be influenced by a combination of genetic, immunological, and environmental factors.
It is important to note that while calcification can occur in these autoimmune disorders, it is also associated with other conditions and injuries. For example, severe injuries, such as level 1 trauma or burns, can lead to soft tissue calcification and heterotopic ossification, which is the formation of bone in soft tissues. Additionally, certain patients with conditions like ankylosing spondylitis or DISH (diffuse idiopathic skeletal hyperostosis) have a tendency to form bone around surgical sites, leading to calcification and ossification.

Protease plasmin protects soft tissue from turning to bone after severe injuries
Injured muscles can calcify, leading to heterotopic ossification, or bone formation outside of its usual location. This can occur almost anywhere in the musculoskeletal system and is usually seen following an injury to an area. Calcification is the buildup of calcium in areas of body tissue where it doesn't typically exist.
Calcification after severe injuries is a complication that causes pain and limits mobility. Patients with severe injuries, such as level 1 trauma or burns, face many bone-related complications during recovery, including calcification of soft tissue. Calcification can also occur in connective tissue and is believed to be the body's response to inflammation, injury, or certain biological processes.
Protease plasmin, known for its clot-busting role in the blood, protects soft tissue from turning to bone after severe injuries and certain orthopedic surgeries. Plasmin is beneficial for both bone healing and the protection of soft tissue from calcification. It is a protease that is specifically activated in virtually all areas of injury and is involved in many tissue repair networks.
Vanderbilt researchers discovered that early inappropriate activation of the enzyme plasmin caused by severe injury is a trigger of systemic inflammatory response syndrome and resulting organ failure. This finding could help minimize bone-related complications in severely injured patients.

Frequently asked questions
Calcification occurs when calcium builds up in areas of body tissue where calcium doesn't usually exist.
Calcification is the body's response to inflammation, injury, or certain biological processes. Certain patients, such as those with ankylosing spondylitis or DISH, are predisposed to form bone around surgical sites. Calcification can also be caused by autoimmune disorders such as the CREST syndrome or dermatomyositis.
Calcification treatment depends on several factors. Minor calcifications aren't considered dangerous, but more severe cases may require surgery. Getting regular check-ups is important to monitor potential complications.
