==[[Muscle Trauma]]==

−

*Due to:

−

**Direct transection of myofibres

−

**Compression of myofibres

−

**Secondary from haemorrhage (bruising)

−

***May increase muscle pressure -> [[Muscles Degenerative - Pathology#Ischaemia|ischaemia]] -> [[Muscles Degenerative - Pathology#Necrosis|necrosis]]

−

**Partial rupture - ''e.g.'' of diaphragm in road traffic accident

−

**Complete rupture - ''e.g.'' quadriceps of racing greyhounds

−

**Myorrhexis (tearing) - ''e.g.'' slippery floor causing 'splits' in cattle -> adductor muscle tear

−

*Healing is by [[Muscle Regeneration|regeneration]]

−

*Fibrosis (scarring) will compromise function

−

*During [[Bones Fractures - Pathology|fractures]], fragments may cause further trauma if moved
