Dead arm syndrome starts with repetitive motion and forces on the posterior capsule of the shoulder. The posterior capsule is a band of fibrous tissue that interconnects with tendons of the rotator cuff of the shoulder. Four muscles and their tendons make up the rotator cuff. They cover the outside of the shoulder to hold, protect and move the ...
Late untreated crush syndrome death is caused by renal failure, coagulopathy and hemorrhage, and sepsis. [11] Due to the risk of crush syndrome, current recommendation to nonprofessional first-aiders (in the UK) is to not release those with a crush injury who have been trapped for more than 15 minutes.

Compartment syndrome. Compartment syndrome is a common complication of crush injury as a consequence of oedematous tissue injury, redistribution of fluid into the intracellular compartment and bleeding. Established compartment syndrome may result in worsened systemic crush syndrome and irreversible muscle cell death. [4] Acute kidney injury.
The muscle damage is most usually caused by a crush injury, strenuous exercise, medications, or a substance use disorder. [3] Other causes include infections , electrical injury , heat stroke , prolonged immobilization, lack of blood flow to a limb , or snake bites [ 3 ] as well as intense or prolonged exercise, particularly in hot conditions ...
The most commonly affected bone is the femur (thigh bone). [1] Other relatively common sites include the upper arm bone, knee, shoulder, and ankle. [1] Diagnosis is typically by medical imaging such as X-ray, CT scan, or MRI. [1] Rarely biopsy may be used. [1] Treatments may include medication, not walking on the affected leg, stretching, and ...
Compartment syndrome is a condition in which increased pressure within one of the body's anatomical compartments results in insufficient blood supply to tissue within that space. [6] [7] [8] There are two main types: acute and chronic. [6] Compartments of the leg or arm are most commonly involved. [3]
Discoloration of the hands, one hand colder than the other hand, weakness of the hand and arm muscles, and tingling are commonly present. [citation needed] Only 1% of people with carpal tunnel syndrome have concomitant TOS. [7] Repetitive motions can cause enlargement of muscles which causes compression of veins.
[58] [59] Loss of bone density (bone demineralization), thought to be due to lack of input from weakened or paralysed muscles, can increase the risk of fractures. [60] Conversely, a poorly understood phenomenon is the overgrowth of bone tissue in soft tissue areas, called heterotopic ossification. [61]
