Final answer:
Excessive stretching of the pelvic ligaments may lead to diastasis symphysis pubis or sacroiliac joint strain. Carpal tunnel syndrome, avascular necrosis, and tennis elbow are not related to pelvic ligament stretching since they involve different body parts.
Step-by-step explanation:
Excessive stretching of the pelvic ligaments may result in diastasis symphysis pubis. This condition involves the separation or abnormal movement of the two sides of the symphysis pubis, which is the joint where the left and right pubic bones meet in the front of the pelvis. It is often associated with pregnancy and childbirth but can also occur due to excessive force or trauma. Sacroiliac joint strain can also occur due to ligament stretch in the pelvic area, as these ligaments support the sacroiliac joints which connect the spine to the pelvis. Conditions such as carpal tunnel syndrome, avascular necrosis, and tennis elbow are not typically associated with stretching of pelvic ligaments as they involve different anatomical regions and etiologies.
