Visceral and Muscle Injuries
The important visceral and muscle injuries include:
- Subcapsular hematoma of the liver.
- Suprarenal hemorrhage.
- Sternomastoid Tumor:
- It is a painless firm swelling, around 2 cm in diameter over the middle or lower third of the sternomastoid muscle.
- Stretching of the muscle during delivery → small hematoma which heals by fibrosis.
- In the majority of cases, it resolves spontaneously and needs nothing more than physiotherapy.
- If it persists, torticollis occurs and may need surgical resection of the fibrous band.
