Pelvic Condition




PREGNANCY RELATED PELVIC PAIN/DYSFUNCTION:

pelvis-surgeon-cardiff-southwalesPain and discomfort around the symphysis pubis (front of the pelvic ring) and low back and buttock pain is very common during pregnancy.  It is reported that up to 25-30% (a quarter) of pregnant women suffer from pregnancy related pelvic discomfort.  Pregnancy related pelvic pain is believed to be caused by a special hormone called Relaxin which is secreted by the body to loosen the ligaments and to help in the delivery of the baby.  These symptoms are otherwise commonly called SPD (symphysis pubis dysfunction).  Most of the symptoms of SPD are believed to resolve in approximately three to six months from childbirth.   Pelvic floor/core stability exercises, a pelvic support and anti-inflammatory medication have been found to be helpful.







POST-PREGNANCY PELVIC INSTABILITY:

A minority of women will go on to suffer from post pregnancy pelvic instability.  The risk factors described are first pregnancy, Cephalo-pelvic disproportion (big baby v small pelvic capacity), breech presentation, prolonged and traumatic labour, twin pregnancy and instrumented delivery such as forceps and ventouse.  







PATHOLOGY:

Due to traumatic child birth the various ligaments and support of the pelvis are injured and ruptured.  In particular the supporting ligaments of the symphysis pubis (front joint of the pelvis) are either sprained or ruptured.  The sacroiliac joints are unlikely to be ruptured because of strong ligamentous support but they are often sprained.  







SYMPTOMS AND SIGNS:

Women with post pregnancy instability complain of severe symptoms of SPD and often suffer from searing pain in the front of the pelvic ring around the symphysis pubis.  They also complain of buttock pain due to the spraining of the sacroiliac ligament.  The pain commonly radiates to the groin and is associated with burning pain to the inner thighs and legs.  These women also feel symptoms of instability in their pelvic ring and complain of grating sensation particularly when turning in bed and changing position.  They struggle to climb stairs and are often unable to carry out manual activities and activities of daily living.  Physical relationships can also be very unpleasant and painful in this condition.  Women with post pregnancy pelvic instability find ambulation extremely difficult and in extreme cases can become wheelchair bound.

Assessment is initiated by obtaining a thorough history and carrying out some special clinical tests.  These women are typically tender over the symphysis pubis and demonstrate clinical signs of pelvic instability.  They are often unable to perform active straight leg raise (lifting a straight leg off the ground).
