This book describes Deltoid Fibrosis, Diagnosis and Treatment and Related Diseases
I was reading about the dangers of vaccination injections in children about the dangers of some preservatives used in vaccines such as formaldehyde and thimerosal (no longer used), aluminium salts when I came across an article on the danger of injection into the deltoid muscle.
The deltoid muscle is the site most frequently used for vaccines.
This site is not often used for self-injection, since its small muscle mass limits the volume of medication that can be injected typically no more than 1 milliliter.
The correct area to give the injection is two finger widths below the acromion process.
At the bottom of the two fingers, will be an upside-down triangle.
The injection is given in the center of the triangle.
Complication from the injection are:
1.Severe pain at the injection site
2.Tingling or numbness
3.Redness, swelling, or warmth at the injection site
4.Drainage at the injection site
5.Prolonged bleeding
6.Signs of an allergic reaction, such as difficulty breathing or facial swelling
An additional danger is the formation of deltoid fibrosis or muscle contracture.
Deltoid fibrosis is a disorder featured by the formation of intramuscular fibrous bands within the deltoid muscle.
These are intramuscular fibrous bands within the deltoid muscle that produce secondary contractures that affect the shoulder joint function and stiffness of the deltoid muscle.
Deltoid Fibrosis is the deltoid muscle contracture forcing fibers in the abduction of the shoulder.
It is a localized fibrosis of the deltoid fibers that more often happen with the abduction contracture of the shoulder as a result.
Scapula swing and secondary scoliosis may be linked with this disorder.
Deltoid fibrosis was linked with fibrous contractures of the quadriceps and gluteal muscles and is probably a similar process.
Cause
The cause is not known.
Risk factors are:
Intramuscular injections,
Trauma and
Other congenital factors.
Pathogenesis
Deltoid fibrosis is most often linked with post-injection changes.
Many drugs have been involved as causative agents: Dramamine, iron, penicillin, lincomycin, pentazocine, streptomycin, tetracycline, vitamins and antipyretic.
There might be a muscle abnormality initially which makes the patients susceptible to injury and development of fibrosis.
There are 3 possible mechanisms for the development of deltoid contracture:
Direct disruption of the muscle by injection or injections linked toxicity
Minor ischemia due to an injection-swelling volume, compression and destruction of vascular fibrosis (fibroblast activity produces tissue edema and collagen production)
Subdivision fibrotic tissue and muscle determine minor ischemic neuropathy.
Injuries caused by repeated injections are considered myotoxicity of deltoid triggering contraction by determining the fibrotic myopathy myositis and secondary degeneration.
Degeneration of the nerve occurs simultaneously by fibrotic compression or ischemia.
Lesions appear in connective tissue.
This may be caused by an enzyme deficiency in collagen degradation, increased rates of collagen production, genetic defects in the regulation of collagen biosynthesis and fibroblast enzyme defect
Signs of deltoid fibrosis are:
Dimpling of the skin
Winging of the scapula
No specific laboratory studies or tests have been shown to be beneficial or helpful in the evaluation or treatment of deltoid fibrosis.
Diagnostic imaging is done for early evaluation.
Surgical treatment is directed on the release of the contracted, fibrous bands.
