Third- and Fourth-Degree Perineal Tear Claims

Third- and fourth-degree perineal tears, also called obstetric anal sphincter injuries (OASI), can have lasting effects. This page explains tear grades, recognition and repair, follow-up, and how legal review approaches them.

The starting point

A perineal tear claim usually focuses less on the tear itself, which can occur despite good care, and more on whether it was recognised, correctly classified, repaired and followed up appropriately, and whether any failure caused lasting harm.

Tear grades

Tears are graded by depth. Third-degree tears involve the anal sphincter muscle, and fourth-degree tears extend further. Pregnancy, Birth and Baby includes tears among recognised birth complications. Exact grading is a clinical matter, and accurate grading at the time of birth is important for repair.

Diagnosis and repair records

Legal review often asks whether a proper examination was done after birth, and whether the tear was identified and graded correctly. It also asks whether repair was performed by an appropriately experienced clinician in suitable conditions.

A tear misclassified as minor may be repaired inadequately.

  • Perineal examination and grading note
  • Repair or theatre record
  • Names and roles of clinicians
  • Records of any instrument use

Follow-up

Experts may examine whether follow-up and referral were arranged after discharge, and how later symptoms were investigated. Delayed recognition of an unrepaired or poorly repaired injury is a common focus of review. This page does not give treatment guidance. Ongoing symptoms should be discussed with your clinicians.

Ongoing effects

Some women recover well, while others have continence, pain, sexual or psychological effects. These can affect work, relationships and decisions about future births. Losses are assessed on actual effects and treatment needs.

Legal review

Obstetric experts consider both standard of care and causation, including whether a different repair or earlier follow-up would probably have produced a better result. Limitation rules vary between jurisdictions and should be confirmed with a local solicitor.

Keep the questions. Gather what you have.

For your next conversation

  • Request the post-birth perineal examination and grading note
  • Request the repair or theatre record
  • Obtain postnatal follow-up and referral records
  • Keep a diary of symptoms and their effect on daily life
  • Record time off work and treatment costs

Common questions

My tear was recorded as second-degree but later found to be worse. Does that matter?

It may be significant. Misclassification can lead to an inadequate repair. Experts would examine whether a reasonable examination at the time should have identified the true extent, and whether correct repair would probably have improved your outcome.

Will a claim affect decisions about future births?

Decisions about future births are clinical and personal, and should be made with your doctors. Expert assessments may consider how the injury affects future birth options as part of understanding your losses.
