Muscle Trauma
- Due to:
- Direct transection of myofibres
- Compression of myofibres
- Secondary from haemorrhage (bruising)
- 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 regeneration
- Fibrosis (scarring) will compromise function
- During fractures, fragments may cause further trauma if moved
