The document summarizes the contracted pelvis, including its etiology, diagnosis, mechanisms of labor, and management. A contracted pelvis is defined as having one or more main diameters reduced below normal. Causes include developmental issues, metabolic diseases like rickets, trauma, and tumors. Diagnosis involves history, examination, and pelvimetry. Management depends on the degree of disproportion, with minor cases attempting vaginal delivery, moderate cases getting a trial of labor followed by c-section if needed, and severe cases proceeding directly to c-section.
