Update: October 2018 Osteosclerosis is a condition called
a symptom of many diseases — consisting in condensing one or
several sections of the bones. As a result, the bone loses its elasticity, and
under normal loads, a fracture can occur precisely in foci
Osteosclerosis of the bones does not show itself for a long time, while the process
goes deeper and can lead to immobilization of the limb,
development of tumors, pathological fractures. Detect
disease by radiography, and according to its results orthopedists
or traumatologists prescribe treatment: either conservative or
Causes of pathology
Pathology occurs when bone synthesis goes faster than its
destruction. This happens when:
- hereditary diseases. This is osteopetrosis or
marble disease, osteopoikilia, meleoreostosis, pycnidisostosis,
dysosteosclerosis, scleroosteosis, Paget’s disease;
- frequent bone injuries;
- poisoning of the body with various substances, mainly
heavy metals (lead, strontium, fluorine);
- frequent and prolonged loads on the limbs or spine,
when microtraumas are constantly appearing in the bones
restore bone synthesizing cells;
- osteosclerosis of the joints occurs with a sedentary lifestyle,
which is due to the fact that the nutrition of the articular parts of the bone
comes from joint fluid – while moving;
- chronic bone diseases like chronic
osteomyelitis, bone tuberculosis;
- insufficient nutrient intake – with
malnutrition or some metabolic
- obesity, which in itself represents an increased load
on the bone;
- tumors or bone metastases. Bone metastases are characteristic.
for many types of cancer, especially for lung, prostate, lactic
- osteochondrosis, for example, of the cervical spine;
- transferred vascular diseases when the diet was broken
- weak (untrained or affected) muscles that
separate joints are set in motion;
- blood diseases: leukemia, myelofibrosis;
- transferred operations on the bones.
Types of osteosclerosis
The focus of osteosclerosis can be:
- Physiological (normal) when it appears in the growth zone
bones in a teenager.
- Pathological. It arises as a result of various reasons about
which we talk below.
If osteosclerosis foci are numerous, and they are located
�“Out of tune” (this can be seen on the radiograph), the disease is called
spotty. It can be large-focal and small focal. Can
be with rare or multiple tricks.
If it is clear that one large area of osteosclerosis consists of
many small foci, it is called uniform.
There is also a classification that takes into account the quantity and volume.
compacted bones. Proceeding from it, osteosclerosis happens:
- limited (local, focal): is within one
bones. It is observed mainly in the outcome of inflammatory bone.
- diffuse: uniformly affects the tubular bones, mainly in
areas of their diaphysis (for example, in chronic osteomyelitis);
- common: hit a few bones or a patch
bone system (for example, lower limbs and pelvis, bones
shoulder girdle and so on);
- systemic (generalized): foci of bone
substances are found in the bones of the entire skeleton. It develops with
systemic diseases (leukemia, marble disease).
Depending on the underlying causes, osteosclerosis can be:
- functional: the same as physiological – arises in
areas of growth zones when bone growth stops;
- идиопатическим – связанным с пороками развития bones;
- post-traumatic – resulting from bone healing
after her fracture;
- воспалительным: развившимся в результате воспаления bones;
- reactive – arising in response to a tumor or malnutrition

In addition, bone osteosclerosis is isolated, when lesions are affected.

The latter type of disease is also called osteosclerosis.

The causes of this type of osteosclerosis are an excessive load on
joints, degenerative diseases (deforming osteoarthrosis),
swelling, inflammation. If at the same time a person has vascular
diseases, metabolic disorders, chronic infections –

Symptoms of this condition
The disease does not manifest itself for a long time: a person suffers
degenerative or inflammatory disease of the bone or joint, and
has no idea that smaller or larger portions of it steel bones

Only when the sealing areas become quite large, and

Osteosclerosis of the ileum for a long time is asymptomatic.
You can suspect it by the appearance of pain in the sacrum,
arising from long walking or after a long sitting.

In osteosclerosis of the articular surfaces of the Ilium and

- Massages in the affected areas – if there are no signs
- Exercise therapy with metered load on the affected limbs – in
cases where there is no acute inflammations;
- physiotherapy: magnetic therapy, UHF, electrophoresis,
- a daily calorie diet up to 1800 kcal / day – if
required to reduce body weight.
Surgical treatment is carried out in cases of:
- stenosis of the bone marrow canals (then
bone marrow transplantation);
- if necessary, remove lesions containing necrotic

All that can be done to prevent osteosclerosis –
- avoid hypodynamia;
- sleep on an orthopedic mattress;
- maintain body weight in the normal range;
- perform at least simple exercises;
- eat well;
- time to treat inflammatory and neoplastic diseases;
- to refuse from bad habits.
