In some cases spicules ofbone develop at certain points in the pelvis, projecting into its cavity. They arevery apt to injure the uterus or the descending head. Perforation of the uterusis common under these circumstances. After fracture of the bones irregularcallus may also form projections. Other pelvic tumors are osteosarcomata (), enchondromata, sarcomata, fibromata, cysts, and carcinomata. Their sizewill form the criterion for the difficulty offered in labor. The cysts may be hyda-.
