Muscular Lesion are very common and include:
Acute direct: contusion (stupor, ecchymosis, haematoma, muscolar compression);
Acute indirect: contracture, straining, pulled muscle of muscular strain of I° - II° - III°, muscular injury;
Chronic post traumatic: liquid stratum, post traumatic fibrosis, serum-haematic cyst, muscular calcifications, ossifyng myositis.
The Acute Direct include the contusion: an acute, traumatic lesion of the soft tissues, caused by a violent impact of a body with an even surface.
The Acute Indirect include
Contracture:it is a permanent stiffening of the muscle which, to avoid an excessive lenghthening, presents a “contracture for defence”;
Strain: it is an elongation of the muscular fibres in absence of a real anatomical lesion;
Pulled muscle or muscular sprain: it is a lesion characterized by a discontinuity of the muscular fibres without interruptions of the connective tissue that can be joined up with lesions of the blood vessel structures with consequent ecchymosis or haematoma. Clinically, it is characterized by a sudden pain with a symptomatology both objective and subjective, and a functional impotence which is directly proportional to the seriousness the lesion itself;
Muscular fracture: this is a total or partial interruption of a muscle that can happen because of the action of a contusive body that strikes the muscle while it is actively contracted, or because of a sudden contraction.
The chronic post traumatic generally due to iatrogenic causes (wrong first rescue and therapeutic approach to the lesion, non-indicated or forced massotherapy in some cases, and wrong times of recovery), we can distinguish:
